    Full Text Available A huge left renal capsular leiomyoma mimicking retroperitoneal sarcoma presented in a patient as an abdominal mass. Computed tomography displayed a large heterogeneous retro-peritoneal mass in the left side of the abdomen with inferior and medial displacement as well as loss of fat plane with the left kidney. Surgical exploration revealed a capsulated mass that was tightly adherent to the left kidney; therefore, total tumor resection with radical left nephrectomy was performed. Histopathology ultimately confirmed the benign nature of the mass. This is the largest leiomyoma reported in literature to the best of our knowledge.

    We report a case of retroperitoneal cystic lymphangioma in an 65-year-old male. Two years prior to this admission, a mass was incidentally detected by ultrasound during hospitalization for the treatment of lung cancer. Ultrasound study showed a multiloculated cystic mass with debris and CT revealed a fat-fluid level within the mass. On two years follow-up, the mass has changed into a unicameral mass without internal echogenicity on US and homogeneous water-density mass on CT. The mass was removed by surgery and confirmed as retroperitoneal cystic lymphangioma

Case descriptions: A 69-year-old male presented with pain in the left waist and back of 1 month duration. The renal abscess was suspected by magnetic resonance imaging before operation. The perirenal hematoma was cleaned by operation. In another case, the patient had a functional solitary left kidney compressed by a huge retroperitoneal mass and uropenia appeared. Results: The first patient died of adult respiratory distress syndrome after surgery. The second patient died of cardiac insufficiency and pulmonary embolism on the second day after evacuation of retroperitoneal hematoma. Conclusion: Conservative surgery, such as selective arterial embolization, is a reasonable approach in patients with chronic spontaneous retroperitoneal and perirenal space hemorrhage and with poor general condition. We strongly recommend drainage or interventional therapy, but not a major surgery, in patients with poor condition. Keywords: kidney, spontaneous, retroperitoneal, hemorrhage, surgery

    Retroperitoneal leiomyosarcomas are very rare malignant neoplasms. They are built up of smooth muscle cells. They can be found beyond the retroperitoneal space in the uterus, the stomach, the intestines, the blood vessel walls and the skin. This type of tumour grows slowly and gives no characteristic clinical symptoms. This results in late diagnosis, when they grow to a huge size. Retroperitoneal leiomyosarcomas are most frequently described in the literature in the fifth or sixth decade of life. There are no biochemical markers which could suggest the development of leiomyosarcoma. The basic diagnostic examination includes: ultrasound and computer tomography of the abdomen. The fundamental treatment of retroperitoneal leiomyosarcomas consists in aggressive surgical treatment - complete tumour resection. Large size of the tumour can make it difficult to perform radical surgery. In the case presented in this report, our team managed to remove a retroperitoneal leiomyosarcoma completely despite its huge mass and size (300 x 200 mm). Data from the literature indicate that a complete resection of the tumour is the most significant prognostic factor in the case of patients with retroperitoneal leiomyosarcoma. The efficacy of radiotherapy and chemotherapy has not been proved. The other unfavourable prognostic factor in the course of sarcomas is the age of the patient, below 50 years old. The patient presented in the report is a 31-year-old woman, which is associated with a worse prognosis. According to some authors, the size of the tumour is not significant for the fast recurrence of the disease, whereas others state that it is. The case was presented because of such a huge leiomyosarcoma being rarely found in the retroperitoneal space, the age of the patient and the asymptomatic course of the disease. (authors)

    Full Text Available Excision of a suspected retroperitoneal, duodenal duplication cyst was performed in a pre-operatively normotensive patient under combined epidural and general anaesthesia. Intraoperatively, the cystic tumour was discovered to be a retroperitoneal mass, free from duodenal or adrenal origin. Development of severe arrhythmias, ST segment changes and hypertensive spikes during cyst handling and dissection suggested the possibility of a catecholamine-secreting tumour. These were managed effectively with pharmacological agents. Subsequently, histopathology of the specimen revealed a paraganglioma. Vasoactive tumour has to be suspected in every patient undergoing anaesthesia for retroperitoneal cystic lesion.

    Retroperitoneal foregut duplication cyst is an extremely rare congenital malformation. Pathologically, this lesion contains both gastric mucosa and respiratory type mucosa; radiologically, it is often challenging to differentiate it from the other cystic neoplasms that present a similar appearance. We report on a case of retroperitoneal foregut duplication cyst that was lined by both gastric and pseudostratified ciliated columnar epithelium, and it was also accompanied by a pancreatic pseudocyst. Initially, it presented with peripancreatic and intrapancreatic cystic masses in an asymptomatic 30-year-old man, and this man has since undergone surgical resection

    Purpose: To evaluate the different imaging findings (US, CT and MRI) in retroperitoneal schwannoma. Materials and methods: 5 patients (3 male and 2 females) with a diagnosis of retroperitoneal schwannoma were retrospectively evaluated. Ages ranged from 33 to 63 years (means 54 years). The images (US, CT and MR) were analyzed and correlated to histopathologic results. Results: The most frequent clinical finding was abdominal pain (60%). A presumptive diagnosis prior to surgery was suggested in 3/5 cases that had well-defined masses with a predominant cystic appearance. All patients underwent surgery with tumoral resection. Only 2 patients (40%) had recurrence within a three years period of follow-up. Conclusion: Retroperitoneal schwannoma is an infrequent tumor. In our series, no pathognomotic features were observed on US, CT or MRI. However, 3/5 tumors showed high signal intensity on T2-weighted images due to cystic areas. (author)

    Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

    Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults. Neuroblastoma, rhabdomyosarcoma, benign teratoma and lymphoma are the common retroperitoneal neoplasms. In this review, the clinical and CT futures of common retroperitoneal neoplasms in children are described. Coarse, amorphous, and mottled calcification are very common in neuroblastoma. Paraganglioma tends to show marked and early enhancement and may present with clinical symptoms associated with the excess catecholamine. Sarcomas are often very large and have heterogeneous appearance. Imaging cannot be reliably used to identify the type of retroperitoneal sarcomas due to overlapped radiographic features. In children, lipoblastoma is the most common lipomatous tumor in the retroperitoneum. The percentage of visible fat in tumor varies depending on the cellular composition of the lesion. The CT characteristics of teratoma are quite variable, which may be cystic, solid, on a combination of both. Typically teratoma appears as a large complex mass containing fluid, fat, fat-fluid level, and calcifications. Lymphoma is often homogeneous on both enhanced and unenhanced CT scans. Necrosis and calcification are rare on CT. In conclusion, making a final histological diagnosis of retroperitoneal tumor base on CT features is not often possible; however, CT can help to develop a differential diagnosis and determine the size and extent of the retroperitoneal neoplasms.

    Full Text Available Lymphangioma of the pancreas is a rare benign tumor of lymphatic origin. Retroperitoneal lymphangiomas account for 1% of all lymphangiomas. Herein, we report a case of cystic pancreatic lymphangioma diagnosed in 34 year-old female patient who was hospitalized for a slight pain in the epigastrium and vomiting. Radiological imaging revealed a large multiloculated cystic abdominal mass with enhancing septations involving the upper retroperitoneum. During the laparoscopic surgery, a well circumscribed polycystic tumor was completely excised preserving the pancreatic duct. The patient made a complete recovery and is disease-free 12 months postoperatively.

    Primary retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare tumor: its histogenesis and its biological behavior remain speculative. Since most retroperitoneal tumors are malignant, a preoperative diagnosis of benignity is essential and it can be reached through imaging examinations, allowing a conservative management approach. We describe the case of a 52-year-old woman with abdominal pain and a palpable mass. Computed tomography of the abdomen revealed a retroperitoneal cystic mass, which was resected successfully through laparoscopy and diagnosed as PRMC. Although there are no pathognomonic, clinical or radiological findings for PRMC, it should be included in the list of differential diagnoses and its imaging criteria of benignity should always be sought, with the aim to exclude malignant tumors.

    Full Text Available Retroperitoneal primary mucinous tumor is an extremely rare malignancy. To date, only 52 cases of primary retroperitoneal mucinous cystadenocarcinoma (PRMC have been reported in the literature, with the majority being women. Our patient is the 5th known male case. A 57-year-old male patient presented with a two year history of an undefined abdominal pain.Computed tomography demonstrated a 12 x 9.5 cm cystic mass lesion extending superiorly from right iliac fossa, while localizing below the abdominal wall and close to the psoas muscle. According to the laparotomy, iliopsoas muscle was infiltrated by the mass in the retroperitoneal region. Pathological diagnosis was mucinous cystadenocarcinoma . The asymptomatic patient was followed up without applying an adjuvant chemotherapy, since the clinical course of the tumor is known to be slow and postoperative therapy is not recognized as a standardized treatment. The clinical course of PRMC is generally indolent, however, it may manifest an aggressive course, as well. It has no definitive and clear pathogenesis. The treatment is contentious, as well. Diagnosis and treatment require surgical excision but data on adjuvant chemotherapy is limited.

    Full Text Available Primitive neuroectodermal tumor (PNET is a rare “small round blue cell tumor” that is diagnosed by open biopsy or percutaneous biopsy of the lesion under radiologic guidance. In this case report, we present a novel approach to the diagnosis of a retroperitoneal PNET by endoscopic ultrasound- (EUS- guided fine needle aspiration (FNA. A 35-year-old man presented with the history of left-sided flank pain and swelling of 3-weeks duration. Computerized tomography (CT scan of his abdomen revealed a 12.8 × 13 × 12.5 cm cystic and solid mass arising from the retroperitoneum and displacing the third and fourth portions of the duodenum. He underwent EUS which revealed a well-circumscribed heterogeneous mass abutting the inferior portion of the stomach. EUS-FNA of the mass revealed malignant cells consistent with primitive neuroectodermal tumor (PNET/Ewing's sarcoma. EUS-guided FNA is an appropriate technique for diagnosing retroperitoneal PNET/Ewing's sarcoma.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two. Conclusions: US

    Lymphangiomas occurs in children quite frequently. They are most commonly localized in the head, neck, axilla, chest, abdomen, and retroperitoneum. Lymphangiomas of the scrotum are very rare and are usually clinically silent, so they are a challenge for radiologists performing US examination in children. They are obliged to differentiate the following lesions: torsion of the testicle, scrotal hernia, hydrocoele, and epididymal cyst, in addition to the masses of primary extra-testicular localization such as hemagioma, congenital vascular malformations, fibromas, and malignant tumors. Additional difficulties appear in boys who present acute scrotum syndrome. The paper reports the diagnostics and treatment of a huge multicystic lymphangioma situated in he scrotum and retroperitoneum of a 12-year-old boy who had fallen from a bicycle and presented acute scrotum. The lesion of the scrotum was surgically excised. Retroperitoneal lymphangioma was detected during this operation. Subsequent diagnostics was based on ultrasonography, computerized tomography, and magnetic resonance imaging of the abdominal cavity. The lymphangioma of the retroperitoneum was resected. The patient shows no evidence of recurrence after 7 years. Cystic lymphangiomas are rare but benign intra-scrotal, extra-testicular, painless masses in children. They are sonographically multicystic or multiloculated abnormalities and may show infiltrative extension to the perineum, retroperitoneum, or abdomen. Recognition of this entity and its extent is important for correct clinical management and may be for planning treatment. (author)

A mucinous cystadenoma with no malignant cells in peritoneal washing was detected in histopathology examination. This report describes a rare case of a successful vaginal delivery despite a huge cystadenoma of the right ovary complicating the pregnancy.

  8. Ormond's disease or secondary retroperitoneal fibrosis? An overview of retroperitoneal fibrosis

    Retroperitoneal fibrosis represents a rare inflammatory disease. About two thirds of all cases seem to be idiopathic (= Ormond's disease). The remaining one third is secondary and may be ascribed to infections, trauma, radiation therapy, malignant diseases, and the use of certain drugs. Up to 15 % of patients have additional fibrotic processes outside the retroperitoneum. The clinical symptoms of retroperitoneal fibrosis are non-specific. In sonography retroperitoneal fibrosis appears as a retroperitoneal hypoechoic mass which can involve the ureters and thus cause hydronephrosis. Intravenous urography and MR urography can demonstrate the typical triad of medial deviation and extrinsic compression of the ureters and hydronephrosis. CT and MRI are the modalities of choice for the diagnosis and follow-up of this disease. The lesion typically begins at the level of the fourth or fifth lumbar vertebra and appears as a plaque, encasing the aorta and the inferior vena cava and often enveloping and medially displacing the ureters. In unenhanced CT, retroperitoneal fibrosis appears as a mass that is isodense with muscle. When using MRI, the mass is hypointense in T1-weighted images and of variable intensity in T2-weighted images according to its stage: it may be hyperintense in early stages, while the tissue may have a low signal in late stages. After the administration of contrast media, enhancement is greatest in the early inflammatory phase and minimal in the late fibrotic phase. Dynamic gadolinium enhancement can be useful for assessing disease activity, monitoring response to treatment, and detecting relapse. To differentiate retroperitoneal masses, diffusion-weighted MRI may provide useful information. (orig.)

    An 86-year-old man was admitted to our department with complaints of intermittent upper abdominal pain. Ultrasonography of the abdomen showed dilated extrahepatic bile ducts containing stones; however, the gallbladder was not clearly identified. Magnetic resonance cholangiopancreatography showed dilated extrahepatic ducts and choledocholithiasis without gallbladder visualization. The stone extraction was performed with endoscopic sphincterotomy. Three-dimensional images using spiral-computed tomography after intravenous-infusion cholangiography clearly demonstrated an obstruction of the cystic duct. The patient was scheduled for laparoscopic cholecystectomy. At laparoscopy, the gallbladder fossa was not identified on the undersurface of the liver. Despite a thorough examination of the intrahepatic (left-sided within the lesser omentum), retroperitoneal, retrohepatic (within the falciform ligament), retroduodenal, and retropancreatic areas using laparoscopic ultrasonography, the gallbladder was not found. After careful dissection of the hepatoduodenal ligament, the dilated extrahepatic bile duct and a 1-cm length of hypoplastic cystic duct were found. Gallbladder agenesis is usually accompanied by the lack of the cystic duct. The present case is the third report of gallbladder agenesis with a patent or hypoplastic cystic duct.

    Full Text Available Soft tissue sarcomas represent less than 1% of all human neoplasms. One-third of malignant tumors that arise in the retroperitoneum are sarcomas and liposarcoma is the most common retroperitoneal sarcoma and is known to grow to giant sizes, slow progress and few late symptoms. We report the case of a 40 year old woman with a giant retroperitoneal liposarcoma. A laparotomy was performed and a multilobulated tumor of 20 centimeters of diameter arising from retroperitoneum. The histological features were suggestive of pleomorphic liposarcoma weighing 8.5 Kilograms

    Purpose: In relapsing testicular cancer, additional chemotherapy is followed by abdominal CT. If residual lesions are found, retroperitoneal lymphadenectomy is considered. We studied retrospectively whether morphological criteria can help in selected cases in deciding about lymphadenectomy by distinguishing between vital tumor, scarring and mature teratoma. Methods: In 26 patients who had been treated by salvage chemotherapy and retroperitoneal lymphadenectomy for non-seminomatous testicular cancer between 1990 and 1997, abdominal computed tomography and histology were correlated. Results: Histological examination found scarring in 10 patients, vital tumor in 6, mature teratoma in 4, and simultaneous teratoma and vital tumor in 6. A single CT criterion for distinguishing between these histologies was not identified. In two patients with large masses which were partly cystic and partly solid vital tumor and teratoma were verified. Scarrings may be expected in cystic lesions at the level of the renal hilus which are lined by a thin and smooth wall. Size did not matter. Conclusion: Accurate differentiation between vital tumor and necrosis was not possible. Before lymphadenectomy CT, however, localised lesions. (orig.)

    We report on a 16-year-old male with paratesticular rhabdomyosarcoma who underwent retroperitoneal lymph node dissection due to a stage I tumor (normal retroperitoneal computed tomography). The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

    Full Text Available Paratubal cysts are asymptomatic embryological remnants. These cysts are usually diagnosed during adolescence and reproductive age. In general, their sizes are small but can be complicated by rupture, torsion, or hemorrhage. Paratubal cysts are often discovered fortuitously on routine ultrasound examination. We report a 19-year-old female patient who presented with irregular menses and abdominal pain. Ultrasound examination revealed a huge cystic mass at the right adnexial area. The diagnosis was confirmed as paratubal cyst during laporotomy and, hence, cystectomy and right salpingectomy were performed. [Cukurova Med J 2016; 41(3.000: 573-576

    Objective: To analyze CT manifestation of retroperitoneal gigantic liposaxcoma and to improve the image understanding. Methods: Five cases of retroperitoneal gigantic liposarcoma confirmed by surgery and pathology in our hospital were collected. Plain and enhanced CT scan were performed. Results: Of five cases, one was substantive, two was pseudocyst and two was mixed tumor. Several patterns of enhancement such as strip, floccule, irregular patchy or nodular enhancement were revealed inside the lesions on enhanced CT scan. And strip-form of high density enhancement was a typical type. Conclusion: CT examination could determine the tumor's location, size and density, together with the relationship to adjacent organizations CT scan is an important method in diagnosing retroperitoneal gigantic liposarcoma.

    An evaluation of the efficacy of endoscopic methods for the diagnosis and correction of surgical and immunological complications after retroperitoneal pancreas transplantation. From October 2011 to March 2015, 27 patients underwent simultaneous retroperitoneal pancreas-kidney transplantation (SPKT). Diagnostic oesophagogastroduodenoscopy (EGD) with protocol biopsy of the donor and recipient duodenal mucosa and endoscopic retrograde pancreatography (ERP) were performed to detect possible complications. Endoscopic stenting of the main pancreatic duct with plastic stents and three-stage endoscopic hemostasis were conducted to correct the identified complications. Endoscopic methods showed high efficiency in the timely diagnosis and adequate correction of complications after retroperitoneal pancreas transplantation. © 2017 John Wiley & Sons A/S.

    Abstract Rationale: Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. Patient concerns: A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. Diagnoses: CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Interventions: Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. Outcomes: His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Lessons: Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury. PMID:29879068

    The retroperitoneal space (RPS) is an anatomical area bounded dorsally by the sublumbar musculature and ventrally by the peritoneal surface of the abdomen. The RPS communicates with the pelvic space and mediastinum and is subject to primary diseases of the RPS connective tissue and to extension of disease from organs lying within or adjacent to it. Primary diseases include retroperitonitis, pneumoretroperitoneum, non-neoplastic retroperitoneal space-occupying lesions, and primary neoplasms of the RPS. Primary diseases of kidneys, ureters, adrenal glands or retroperitoneal lymph nodes may extend into the RPS, and the RPS may be the site of metastatic neoplastic disease. Clinical signs suggestive of retroperitoneal disease include lumbar pain, pyrexia, lethargy, and signs referable to organs within the RPS

    Full Text Available Cystic fibrosis (CF is the most common autosomal recessive disorder in Caucasian populations. Individuals with CF have seen significant increases in life expectancy in the last 60 years. As a result, previously rare complications are now coming to light. The most common of these is cystic fibrosis-related diabetes (CFRD, which affects 40–50% of CF adults. CFRD significantly impacts the pulmonary function and longevity of CF patients, yet a lack of consensus on the best methods to diagnose and treat CFRD remains. We begin by reviewing our understanding of the pathogenesis of CFRD, as emerging evidence shows the cystic fibrosis transmembrane conductance regulator (CFTR also has important roles in the release of insulin and glucagon and in the protection of β cells from oxidative stress. We then discuss how current recommended methods of CFRD diagnosis are not appropriate, as continuous glucose monitoring becomes more effective, practical, and cost-effective. Finally, we evaluate emerging treatments which have narrowed the mortality gap within the CF patient group. In the future, pharmacological potentiators and correctors directly targeting CFTR show huge promise for both CFRD and the wider CF patient groups.

    The good prognosis of retroperitoneal and lateral pelvic lymphadenectomy has raised the question of whether total mesorectal excision is suitable for adequate staging of rectal adenocarcinoma patients. The aims of this study were to determine the accuracy of dye and probe detection of metastatic retroperitoneal and/or lateral pelvic nodes and to define the upstaging impact of retroperitoneal and lateral pelvic lymphadenectomy in rectal adenocarcinoma patients. Ninety-seven rectal adenocarcinoma patients were submitted to total mesorectal excision and retroperitoneal and lateral pelvic lymphadenectomy. Lymphoscintigraphy using technetium-99 m-phytate and patent blue was performed to detect blue and/or radioactive retroperitoneal and/or lateral pelvic nodes which were examined histopathologically and immunohistochemically with a step-sectioning technique. Mesorectal mean node count was 11.5 and retroperitoneal and/or lateral pelvic node was 11.7. Retroperitoneal and lateral pelvic lymphadenectomy identified metastases in 17.5%, upstaging 8.2%. Variables related to metastatic retroperitoneal and/or lateral pelvic nodes were the following: Stage III in total mesorectal excision specimens (P<0.04), pT3/pT4 tumors (P=0.047), high levels of carcinoembryonic antigen (P=0.014) and large tumors (P=0.03). Marker migration to retroperitoneal and/or lateral pelvic nodes occurred in 37.1%, upstaging 11.1%. The markers' accuracy in the detection of metastatic retroperitoneal and/or lateral pelvic nodes was 100%. Retroperitoneal and lateral pelvic lymphadenectomy detected an important rate of metastatic retroperitoneal and/or lateral pelvic nodes (RLPN), resulting in upstaging. When markers migrated, they were able to detect RLPN metastases. The use of markers should be improved in the identification of RLPN metastases for selective indication of retroperitoneal and lateral pelvic lymphadenectomy. (author)

    The usefulness and safety of imatinibfor neoadjuvant chemotherapy for resectable gastrointestinal stromal tumor(GIST) has not been established. We reported a case of a huge GIST of the stomach that was safely resected following preoperative imatinibtherapy. A 69-year-old man was hospitalized with abdominal fullness which increased rapidly from a month ago. A CT scan showed a huge tumor containing solid and cystic component which was accompanied by an extra-wall nodule. The tumor was strongly suspected to be originated from the stomach and EUS-FNA revealed GIST. We diagnosed GIST of the stomach and initiated preoperative adjuvant chemotherapy with imatinib because there was a risk for the break of tumor capsule and composite resection of the other organs without prior chemotherapy. After the administration of imatinib4 00 mg/day for 6months, the solid component was decreased in size and its' activity by PET-CT had declined, but the size of the cystic component was not changed and the patient's complaint of fullness was not reduced. Then, after a week cessation of imatinib, we performed surgical removal of the tumor with partial gastrectomy without surgical complication during and after the operation. Imatinibwas resumed 2 weeks later postoperatively and 1 year and 8 months has passed since the operation without recurrence. Neoadjuvant chemotherapy with imatinibhas the potential to become an important therapeutic option for the treatment of huge GISTs.

    Full Text Available Echinococcosis is a parasitic infestation caused by Echinococcus granulosus and is an endemic disease in many parts of world. The symptoms and signs depend on the location and size of the cyst. Renal cystic echinococcosis or hydatid cyst (HC disease of the kidney is extremely rare and constitutes only 2-4% of all cases of hydatid disease (HD. We present a 39-year-old male patient who was referred to our outpatient clinic with cystic right kidney mass that was incidentally diagnosed during hepatobiliary ultrasound for chronic hepatitis B evaluation. Routine blood tests were normal without eosinophilia. Indirect haemagglutination test was negative. Abdominal kidneys, ureters, and bladder X-ray showed an 83×95 mm sized curvilinear calcification in the right upper abdominal quadrant. Abdominal computed tomography scan and magnetic resonance imaging demonstrated a 10x9x10 cm sized cystic mass arising from the middle pole of the right kidney, destructing the whole upper pole and extending into the liver. Daughter vesicles were present in the cystic lesion suggesting renal HD. Right retroperitoneal exploration with flank approach and right radical nephrectomy was performed without any complications. Pathology confirmed HC lesion. Following surgery, albendazole 400 mg per os twice daily for 4 weeks was suggested.

    Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit. In particular, the most common retroperitoneal sarcoma subtypes, liposarcoma and leiomyosarcoma, have characteristic imaging appearances which are discussed. This review therefore aims to set the context and guide clinicians through a diagnostic pathway for retroperitoneal masses in adults which arise extrinsic to the solid abdominal viscera.

    Background: Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck and the mediastinum showed that the LLN had lower enhancement values than normal lymph nodes. Purpose: To elucidate the contrast medium enhancement curves of LLN in the retroperitoneum by comparing the curves of LLN with those of normal lymph nodes, to test whether differences between these curves could be of diagnostic value, and to compare the present enhancement curves of LLN of the retroperitoneum with the curves of LLN of the neck and the mediastinum from previous similar investigations. Material and Methods: Twenty-eight consecutive patients with LLN of the retroperitoneum (three with Hodgkin's lymphoma [HL]) and 21 control patients with sarcomas and thus presumably normal retroperitoneal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and the investigation of mediastinal lymph nodes comprised 24 patients with LLN. Results: The enhancement curves of the retroperitoneal LLN had significantly lower attenuation than those of the retroperitoneal control nodes. A combination of peak contrast value and time to peak adjusted to total body weight yielded a diagnostic accuracy which at the best showed a sensitivity of 90.5% with a specificity of 82.6%. The LLN of the retroperitoneum had higher attenuation values than corresponding nodes of the mediastinum but no significant difference was found between LLN of the retroperitoneum and LLN of the neck in previous similar investigations. Conclusion: The comparison of enhancement curves of retroperitoneal LLN with retroperitoneal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck and of the mediastinum. The best diagnostic accuracy was achieved by combining the parameters peak contrast value and time to peak and adjusting these values to the body weight. Peak enhancement of the

    Retroperitoneal fibrosis or Ormond’s disease is an uncommon process characterized by fibrous tissue proliferation in the retroperitoneum, usually involving the aorta, inferior vena cava and iliac vessels. Obstructive hydronephrosis is often observed due to ureteral entrapment. This report presents a case of the peripancreatic location of the disease. The role of CT and MRI in establishing diagnosis of retroperitoneal fibrosis in an atypical site is discussed. A 52-year-old woman with Hashimoto’s thyroiditis was admitted to hospital because of pain suggesting renal colic. The patient was subjected to ultrasound, CT, and MRI which did not confirm urolithiasis but revealed pancreatic infiltration. Partial pancreatectomy, left-sided adrenalectomy and splenectomy were performed. Retroperitoneal fibrosis was diagnosed in the histopathological examination. A few weeks after surgery, a complication such as pancreatitis developed. Repeat CT confirmed it and showed right hydronephrosis secondary to ureteral involvement by a mass adjacent to the common iliac artery (defined as a typical manifestation of retroperitoneal fibrosis). Nephrostomy and conservative treatment improved the clinical state of the patient. No progression of the process was observed in the follow-up examinations. Atypical retroperitoneal fibrosis remains a diagnostic challenge. Imaging techniques CT and MRI are useful tools for evaluating the extent of Ormond’s disease. An unusual distribution of the process (e.g. peripancreatic location reported in this study) requires histopathological assessment to establish the final diagnosis

    Full Text Available Thymoma is an epithelial neoplasm of the thymus, which commonly lies in the anterior mediastinum and recurrences of thymoma generally are locally, and retroperitoneal recurrence is considered to be rare. A 46-year old Asian woman with invasive thymoma had undergone thymectomy 10 years ago. Computed tomography demonstrated a wellcircumscribed mass in the left retroperitoneal space. The patient had not any symptom including myasthenia gravis. Because on the anterior mediastinum area shows no sign of tumor recurrence and the mass adjacent to the vertebral body, neurogenic tumor was suspected. Surgical resection was performed using a retroperitoneal approach, which revealed the tumor adhering neighboring diaphragm. The tumor was histologically diagnosed to be type B1 thymoma according to the World Health Organization classification. The retroperitoneal mass was an unusual local recurrence after thymectomy. The patients whose had under invasive thymectomy should be evaluated carefully when finding retroperitoneal mass during follow-up.

    Retroperitoneal fibrosis (RF) is an uncommon disease characterized by the presence of a chronic inflammatory reaction, with the formation of fibrous tissue that replaces the normal retroperitoneal tissue, trapping vessels and/or ureters. We present a retrospective review of 3 cases of idiopathic RF studied by means of ultrasound, CT scan and MR imaging, and we assess the features of the MR image, as well as its capacity for characterizing the lesion. We compare the findings obtained with 3 imaging techniques, describing the utility of each one, and their advantages and disadvantages in the assessment of this pathology. In MR, idiopathic RF appears as a hypodense mass in SET1, SE-T2 and STIR sequences. (Author) 9 ref

    Full Text Available Solitary bone plasmacytomas and plasma cell myeloma are clonal proliferations of plasma cells. Many patients with solitary bone plasmacytomas develop plasma cell myeloma on follow-up. We present a case of a 70-year-old man who presented with fracture and a lytic lesion in the subtrochanteric region of the left femur and was assigned a diagnosis of solitary bone plasmacytoma. He received local curative radiotherapy. However, 4 months later his serum M protein and β2-microglobulin levels increased to 2.31 g/dL and 5.965 mg/L, respectively. He complained of abdominal fullness and constipation. Ultrasound and non-contrast CT imaging revealed multiple retroperitoneal masses. Colonoscopic examination was normal. Biopsy of the a retroperitoneal mass confirmed it to be a plasmacytoma. Repeat hemogram, blood urea, serum creatinine, skeletal survey, and bone marrow examination revealed no abnormalities. This is an unusual presentation of plasma cell myeloma, which manifested as multiple huge extramedullary retroperitoneal masses and arose from a solitary bone plasmacytoma, without related end organ or tissue impairment and bone marrow plasmacytosis. The patient succumbed to his disease 8 months after the appearance of the retroperitoneal masses. This case highlights the importance of close monitoring of patients diagnosed with solitary bone plasmacytoma with increased serum M protein and serum β2-microglobulin levels, so that early therapy can be instituted to prevent conversion to plasma cell myeloma.

    Laser excision of a huge-sized supraglottic mass nearly obstructing the airway passage is a real challenge to anesthesiologists. Upper airway obstruction due to neoplasm in supraglottic region, is traditionally managed by preoperative tracheostomy, however, such a common procedure can potentially have an impact on long-term outcome. A 26-year-old patient presented with dysphagia caused by left cystic vallecular synovial sarcoma. The airway was successfully secured via fiberoptic bronchoscopy, followed by excision of the supraglottic tumor with CO2 laser surgery. Tracheostomy was not required. The patient was discharged from the hospital on the 4th day of surgery. This case, highlights the possibility to secure the airway passage without performing preoperative tracheostomy resulting in good outcome and short hospital stay. (author)

  19. Retroperitoneal Gastrointestinal Type Schwannoma Presenting as a Renal Mass

    Full Text Available Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrectomy. Histology reported retroperitoneal schwannoma. Malignant forms are rare however treatment for these is surgical excision. Awareness of the existence of these tumors may help in avoiding unnecessary radical surgeries by opting for biopsy preoperatively.

  20. Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum

    Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

    Knowledge of the surgical anatomy of the retroperitoneum is crucial for surgery of the retroperitoneal organs. Surgery is essential for treatment of retroperitoneal pathologies. The list of these diseases is extensive and comprises acute and chronic inflammatory processes (abscess, injury, hematoma, idiopathic fibrosis), metastatic neoplasms, and primary neoplasms from fibroadipose tissue, connective tissue, smooth and striated muscle, vascular tissue, somatic and sympathetic nervous tissue, extraadrenal chromaffin tissue, and lymphatic tissue. The retroperitoneum can be approached and explored by several routes, including the transperitoneal route and the extraperitoneal route. The retroperitoneal approach to the iliac fossa is used for ectopic renal transplantation. Safe and reliable primary retroperitoneal access can be performed for laparoscopic exploration. The anatomic complications of retroperitoneal surgery are the complications of the organs located in several compartments of the retroperitoneal space. Complications may arise from incisions to the somatic wall, somatic nerves, blood and lymphatic vessels, lymph nodes, visceral autonomous plexuses, and neighboring splanchna.

    Endometriosis is a relatively common gynecologic disease affecting women during their reproductive years. For its diagnosis, magnetic resonance imaging has been shown to have greater specificity than other modalities. Although lesions may show variable signal intensity due to numerous stages of bleeding, the characteristic finding of endometrioma which distinguishes it from other ovarian cystic masses is relatively high signal intensity on T1-weighted images and heterogeneous signal intensity with prominent shading on 72-weighted images. We report an atypical case involving a huge endometrioma. Because of varying signal intensity on T1- and T2-weighted images and scanty shading on T2-weighted images, the findings were misinterpreted and mucinous cystadenoma was diagnosed.

    Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury.

    A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13×20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed. The left ovary demonstrated multiple cystic follicles over the cortex. The histologic diagnosis was a mucinous cystadenoma of the right ovary and a matured cystic teratoma of the left ovary. Both obesity and polycystic ovary syndrome (PCOS) are associated with a greater risk of ovarian tumours, where PCOS could be either the cause or as a consequence of an ovarian tumour. We report an obese, perimenarchal girl with bilateral ovarian tumours coexistent with a polycystic ovary and the metabolic syndrome.

    Full Text Available ABSTRACT A 69-year-old man presented at the hospital with complaints of prolonged stomach pain extending from the week prior. Enhanced computed tomography (CT revealed a low density area in the retroperitoneal space. A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis. Upon admission, prednisolone administration was initiated at a dose of 40mg/day. The size of the retroperitoneal soft tissue mass decreased gradually. Although the dose of prednisolone was tapered to 5mg, the patient is doing well without any sign of recurrence.

    Objective: To determine CT and MRI imaging features in patients with a diagnosis of retroperitoneal lipo sarcoma. Material and Methods: Retrospective analysis of 6 cases, studied with CT and/or MRI in patients with retroperitoneal lipo sarcoma during the last 4 years at our institution. We analyzed symptoms, treatment and prognosis with special focus on the CT and MRI findings and their histological correlation. Results: the most frequent histological subtype in our group of patients was the pleomorphic lipo sarcoma (n=3). In the others cases, 2 were well differentiated and one was round-cell type. Retroperitoneal lipo sarcoma, especially the well differentiated, presented certain imaging patterns which allowed to suspect the subtype of tumor. Recurrences occurred in 50% (n=3). Mortality rate was 33.4% (n=2) (follow-up, 16 months). Conclusion: Both CT and MRI are methods which aid in the detection of this rare disorder, as well as in its diagnosis and follow-up. (author)

    Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

    Retroperitoneal liposarcomas usually present as painless, slow-growing abdominal masses. When masses grow large enough to compress surrounding structures, symptoms may occur. Retroperitoneal liposarcoma clinically manifesting as inguinal hernia is a very rare entity; only 11 cases have been reported. Herein, we present radiographic features of a 37-year-old male with a painless palpable mass in the right groin that was identified as dedifferentiated retroperitoneal liposarcoma herniated through the right inguinal canal.

    Full Text Available Background : Early pathological classification of retroperitoneal masses is important for pin-point diagnosis and timely management. Aims : This study was done to evaluate the usefulness and drawbacks of guided fine needle aspiration cytology (FNAC of retroperitoneal masses covering a period of two years with an intention to distinguish between neoplastic and non-neoplastic lesions and to correlate with histologic findings. Materials and Methods : FNAC was done under radiological guidance in all cases using long needle fitted with disposable syringe. Appropriate staining was done and cytology was correlated with histology which was taken as the gold standard for comparison. Results : Fifty-one patients who presented with retroperitoneal masses were studied. Forty-four lesions were malignant cytologically and 7 were inflammatory (tuberculous. According to radiological and cytologic findings, we classified our cases into four groups: renal tumors, retroperitoneal lymphadenopathy, germ cell tumors, soft tissue tumors. Except for cases of non-Hodgkin lymphoma (NHL and metastatic lesions, we had sensitivity and specificity of 100%. In NHL the sensitivity and specificity were both 50%. In cases of metastatic adenocarcinoma, the sensitivity and specificity were 84.6% and 81.8%, respectively. Conclusions : Ignoring the pitfalls, guided FNAC is still an inexpensive and reliable method of early diagnosis of retroperitoneal lesions.

  12. Rare Presentation of Metastatic Cystic Trophoblastic Tumor in a Patient Without Prior Chemotherapy

    2017-07-01

    Full Text Available Cystic trophoblastic tumor (CTT is a rare testicular germ cell tumor (GCT predominantly seen in post-chemotherapy patients. It is prognostically similar to teratoma and requires no additional chemotherapy in the absence of a nonteratomatous GCT component. We report a case of metastatic CTT in a patient with primary testicular teratoma without prior chemotherapy. Retroperitoneal lymph node metastases contained teratoma, embryonal carcinoma, and CTT. The CTT was β-hCG positive and SALL4 negative by immunohistochemistry (IHC. CTT can arise in metastatic testicular GCT in treatment naïve patients. An important differential diagnosis is choriocarcinoma due to treatment implications, and SALL4 IHC may help.

    Retroperitoneal seminoma is a very rare form of cancer, with embryological origin represented by primordial germ cells from the urogenital ridges left behind during the fetal development. Extragenital germ cell tumors can also occur in the mediastinum or the pineal gland. The aim of this paper is to outline the particularities and draw embryological, histopatological and treatment conclusions regarding extragonadal germ cell tumors. A 43-year-old patient without any additional pathology was admitted for anemia of unknown etiology. The clinical examination revealed through deep abdominal palpation a mass in the left flank, and normal testes. Thoraco-abdomino-pelvic computed tomography (CT) scan showed a large retroperitoneal tumor adjacent to the great vessels in the left lumbo-iliac region. The blood work revealed just a low hemoglobin and hematocrit. With the established diagnosis of retroperitoneal tumor, radical surgical removal was decided. During the surgery, we were required to dissect a large solid encapsulated tumor mass from the aorta and the common iliac artery, starting at the renal pedicle all the way to the left iliac bifurcation. The surgical access was obtained through a transperitoneal left subcostal incision prolonged pararectally. Histopathological and immunohistochemical studies revealed a seminoma of the usual type. After the histological findings, the patient's tumor markers were investigated (LDH - lactate dehydrogenase, βHCG - beta-human chorionic gonadotropin, αFP - alpha-fetoprotein), all values being within normal ranges. In addition, the left testicle was thoroughly reexamined, clinically, through ultrasound and magnetic resonance imaging (MRI) scans, and no abnormalities were observed. After the surgery, the patient followed three courses of chemotherapy (BEP - Bleomycin, Etoposide and Cisplatin). The CT scan done 24 months after surgery found no signs of local or distant tumor recurrence. The patient entered a follow-up schedule

    Percutaneous CT-guided radiofrequency ablation (RFA) is becoming more and more established in the treatment of various neoplasms, including retroperitoneal tumors of the kidneys and the adrenal glands. We report the case of RFA in a patient suffering from the third relapse of a retroperitoneal liposarcoma in the left psoas muscle. After repeated surgical resection and supportive radiation therapy of a primary retroperitoneal liposarcoma and two surgically treated recurrences, including replacement of the ureter by a fraction of the ileum, there was no option for further surgery. Thus, we considered RFA as the most suitable treatment option. Monopolar RFA was performed in a single session with a 2-cm umbrella-shaped LeVeen probe. During a 27-month follow-up period the patient remained free of tumor.

    Full Text Available Although cases of lymphoplasmacytic sclerosing pancreatitis (LSP associated with idiopathic retroperitoneal fibrosis have been reported, the association is rare. We describe a 74-year-old man who presented with obstructive jaundice and weight loss. Nineteen months earlier, he had been diagnosed with idiopathic retroperitoneal fibrosis and treated with bilateral ureteric stents. Initial investigations were suggestive of a diagnosis of LSP, however, a malignant cause could not be ruled out. He underwent an exploratory laparotomy and frozen sections confirmed the diagnosis of LSP. An internal biliary bypass was performed using a Roux loop of jejunum, and the patient made an uneventful recovery. This case illustrates the difficulty in distinguishing LSP from pancreatic carcinoma preoperatively.

    Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

    A 34-year-old woman presented with a left-sided suprarenal space-occupying lesion on sonography. Culture of material obtained during sonographic-guided puncture of the retroperitoneal lesion yielded a mixed flora of Actinomyces and Peptostreptococcus. Initially, a misleading diagnosis of an adrenal pheochromocytoma was initiated by highly positive metaiodobenzylguanidine scintigraphy after chemical chemistry vanillylmandelic acid (VMA) test showed elevated values for adrenaline and its derivatives. Retroperitoneal actinomycosis with yet unproven spread into thoracic and cervical compartments is a particular unusual presentation of an infection with these organisms. Because it may mimic subacute infections or malignant masses in terms of clinical and laboratory findings, radiological diagnosis of this entity may be difficult. The diagnosis was based on results of culture and the response of the patient to long-term penicillin-derivate therapy after surgical drainage of the suprarenal abscess formation. (orig.)

    Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor that typically presents in children and young adults. Occurrence outside of the extremities and the head and neck region is exceedingly rare. We report the case of a 9-year-old boy who presented with recurrent retroperitoneal hemorrhage initially thought to be a manifestation of an underlying bleeding disorder. After comprehensive diagnostic work-up, including multiple negative biopsies, the patient underwent surgical resection of an extensively hemorrhagic intramuscular mass and to date remains well. Pathologic examination confirmed AFH with EWSR1 gene rearrangement. This first documented report of an AFH in a retroperitoneal location in a child highlights the diagnostic difficulties and clinical challenges of AFH arising in an atypical location.

    Full Text Available Introduction. Retroperitoneal sarcomas are uncommon large malignant tumors. Methods. Forty-one consecutive patients with localized retroperitoneal sarcoma were retrospectively studied. Results. Median age was 58 years (range 20–91 years. Median tumor size was 17.5 cm (range 4–41 cm. Only 2 tumors were <5 cm. Most were liposarcoma (44% and high-grade (59%. 59% were stage 3 and the rest was stage 1. Median followup was 10 months (range 1–106 months. Thirty-eight patients had an initial complete resection; 15 (37% developed recurrent sarcoma and 12 (80% had a second complete resection. Patients with an initial complete resection had a 5-year survival of 46%. For all patients, tumor grade affected overall survival (=.006. Complete surgical resection improved overall survival for high-grade tumors (=.03. Conclusions. Tumor grade/stage and complete surgical resection for high-grade tumors are important prognostic variables. Radiation therapy or chemotherapy had no significant impact on overall or recurrence-free survival. Complete surgical resection is the treatment of choice for patients with initial and locally recurrent retroperitoneal sarcoma.

    Full Text Available Enteric duplication cysts lacking anatomic association with the gastrointestinal tract are called isolated enteric duplication cysts (IEDCs. We present an atypical case of a retroperitoneal IEDC with a tortuous tubular complex shape that enfolded the surrounding retroperitoneal fat and mimicked a retroperitoneal teratoma. Multiplanar reconstruction images should be used to evaluate such a lesion correctly. A tortuous tubular complex shape could be a key finding to differentiate from other retroperitoneal cysts.

    To describe a step-by-step guide for successful implementation of the retroperitoneal approach to robotic partial nephrectomy (RPN) PATIENTS AND METHODS: The patient is placed in the flank position and the table fully flexed to increase the space between the 12th rib and iliac crest. Access to the retroperitoneal space is obtained using a balloon-dilating device. Ports include a 12-mm camera port, two 8-mm robotic ports and a 12-mm assistant port placed in the anterior axillary line cephalad to the anterior superior iliac spine, and 7-8 cm caudal to the ipsilateral robotic port. Positioning and port placement strategies for successful technique include: (i) Docking robot directly over the patient's head parallel to the spine; (ii) incision for camera port ≈1.9 cm (1 fingerbreadth) above the iliac crest, lateral to the triangle of Petit; (iii) Seldinger technique insertion of kidney-shaped balloon dilator into retroperitoneal space; (iv) Maximising distance between all ports; (v) Ensuring camera arm is placed in the outer part of the 'sweet spot'. The retroperitoneal approach to RPN permits direct access to the renal hilum, no need for bowel mobilisation and excellent visualisation of posteriorly located tumours. © 2014 The Authors.

    Recently, the concept of interfascial planes has become the prevalent theory among radiologists for understanding the retroperitoneal anatomy, having replaced the classic tricompartmental theory. However, it is a little known fact that the concept remains incomplete and includes embryological errors, which have been revised on the basis of our microscopic study. We believe that the concept not only provides a much clearer understanding of the retroperitoneal anatomy, but it also allows further development for diagnosis and treatment of retroperitoneal injuries and diseases, should it become an accomplished theory. We explain the history and outline of the concept of interfascial planes, correct common misunderstandings about the concept, explain the unconsciously applied therapeutic procedures based on the concept, and present future perspectives of the concept using our published and unpublished data. This knowledge could be essential to acute care physicians and surgeons sometime soon.

    Full Text Available The triton tumor was described in 1932 by Masson, as a peripheral nerve sheath malignancy with rabdomioblástica differentiation. The retroperitoneal location is extremely rare, only nine cases have been reported in children. The clinical picture depends on the size of the tumor and the organs involved, their retroperitoneal location is usually asymptomatic. The mainstay of treatment is the surgical excision of the tumor. We report the case of a child with retroperitoneal location of the tumor. A complete resection of it was performed. The patient had an uneventful postoperative course. He is currently under control. There is no evidence of relapse.

Variants of major retroperitoneal vascular structure were present in 10 (9.9 % patients. Supernumerary renal arteries and veins observed in 5 (4.9 % patients; retroaortic left renal vein type I and II – in 3 (3.0 % patients. Double vena cava inferior detected in 1 (1.0 % patient. Patients with variants of retroperitoneal vascular structures hadn’t vessel injury. There was no difference in intraoperative hemorrhage, transfusion red blood cell, rate of intraoperative hemoglobin and removed paraaortic lymph nodes between the groups. Risk factors for intraoperative bleeding in patients with cervical cancer, depending on the presence or absence of anomalies of retroperitoneal vessels had no significant difference.Conclusion. Despite the fact that the variants of retroperitoneal vascular structures are rare (9.9 %, the success of retroperitoneal surgery is associated with the knowledge of vascular variations which decrease serious, life-threatening complications.

  7. Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

    OpenAIRE

    2014-01-01

    IgG4-related autoimmune pancreatitis is frequently accompanied by relevant lesions in the genitourinary tract and retroperitoneal organs, which cause various clinical problems, ranging from non-specific back pain or bladder outlet obstruction to renal failure. The diagnosis of IgG4-related retroperitoneal fibrosis requires a multidisciplinary approach, including serological tests, histological examination, imaging analysis, and susceptibility to steroid therapy. Radiological examinations are ...

    We report on a 16-year-old male with paratesticular rhabdomyosarcoma who underwent retroperitoneal lymph node dissection due to a stage I tumor (normal retroperitoneal computed tomography). The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

  9. Renal fascial network in retroperitoneal extension of pathologic processes

    International Nuclear Information System (INIS)

    Raptopoulos, V.; Kleinman, P.K.; Marks, S.C. Jr.; Davidoff, A.

    1987-01-01

    The concept of the fascial network emerged after careful analysis of CT scans of 100 patients with a variety of retroperitoneal abnormalities, and after correlation of CT scans and anatomic dissections performed on eight unembalmed cadavers in which different-colored barium-mixed liquid latex was injected in various retroperitoneal compartments. Fat lobules are supported and connected with each other by surrounding thin layers of connective tissue. Thicker connective tissue lamellae (septa) connect and support organs and fascia. Thus, a fascial network infrastructure exists in which fat lobules act as mechanical barriers to the spread of pathologic processes, while these processes tend to take the course of least resistance by spreading along or dissecting within fascial and septal planes. The fascial network acts as a roadway, conduit, and barrier to spread in the retroperitoneum and fatty tissue in general. The insights afforded by the fascial network concept unwind the traditional views regarding the dynamics of retroperitoneal pathology

  10. IgG4-related retroperitoneal fibrosis: a newly characterized disease.

    Retroperitoneal fibrosis (RPF) is a rare disease characterized by chronic, nonspecific inflammatory and sclerotic or fibrotic tissue in the periaortic or periiliac retroperitoneum that encases adjacent structures. There will be a series of clinical manifestations once the proliferated fibrous tissues encase the abdominal aorta, iliac arteries and urinary duct. RPF is generally divided into two types: idiopathic retroperitoneal fibrosis (IRPF) without identified pathogenesis, making up about two-thirds of cases, and secondary retroperitoneal fibrosis. Recent studies on Immunoglobulin G4-related disease (IgG4-RD) reveal that abundant infiltration of IgG4 positive plasma cells is found in biopsies on the mass of RPF of some IRPF patients, which is identified as one spectrum of IgG4-RD and is named IgG4-related RPF. IgG4-related RPF is often misdiagnosed as retroperitoneal visceral malignancy and is treated with surgery. In addition, because of its good response to glucocorticoid, early detection and treatment is important. We review the definition, epidemiology, clinical features, diagnostic criteria, treatment and prognosis of IgG4-related RPF in this article to raise awareness of this newly characterized disease. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    Sciatic hernia is a rare condition and its clinical diagnosis is uneasy. Herniation of pelvic organs as well as of retroperitoneal neoplasm has been reported in the literature. Sciatica occurs as a result of compression of the sciatic nerve by the herniated sac. We present a case of retroperitoneal lipoma in a patient who had lower leg complaint and describe the imaging findings.

    2009-11-01

    Embryologically, the retroperitoneal (extraperitoneal) connective tissue includes three strata, which respectively form the internal fascia lining of the body wall, the renal fascia, and the covering of the gastrointestinal viscera. All organs, vessels, and nerves, that lie on the posterior abdominal wall, along with their tissues and surrounding connective and fascial planes, are collectively referred to as the retroperitoneum. The retroperitoneal space is the area of the posterior abdominal wall that is located between the parietal peritoneum and the fascia. Within the greater retroperitoneal space, there are also several small spaces, or subcompartments. Loose connective tissue and fat surround the anatomic entities, and, to a variable degree, occupy the subcompartments. The multilaminar thoracolumbar (lumbodorsal) fascia begins at the occipital area and terminates at the sacrum.

    Extragastrointestinal stromal tumors (EGIST) are relatively rare, and cases originating in the retroperitoneum even rarer. We report a 60-year-old woman who presented with an EGIST originating in the retroperitoneum. Computed tomography results demonstrated a soft tissue mass on the right side of the retroperitoneum. The tumor abutted the duodenum, head of the pancreas, and right kidney. The mass was surgically proven to be a retroperitoneal tumor and histopathologically proven to be a retroperitoneal EGIST.

    Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

    Since its initial description by Mercan et al. laparoscopic posterior retroperitoneal (PR) adrenalectomy has served as an alternaltive to the transabdominal (TL) approach for the treatment of adrenal pathologies. Robotic adrenal surgery has been reported to improve surgeon ergonomics and facilitate dissection. In patients with bilateral adrenal masses, PR adrenalectomy may be the approach of choice. We herein describe the technique, discuss its limitations and present a critical review of the current literature. © 2015 Wiley Periodicals, Inc.

    Abdominal pain is a very common symptom in all age groups but retroperitoneal fibrosis is a rare differential diagnosis suspected in young patients presenting with nonspecific abdominal pain and symptoms of obstructive uropathy. Presented here is a case of a 16-year-old boy who presented with symptoms of persistent abdominal pain and a previous history of swelling in the left leg. A computed tomography (CT) scan suggested retroperitoneal fibrosis and an exploratory laparotomy and histopathological examination were performed for definitive diagnosis. This case report is intended to promote awareness of retroperitoneal fibrosis in young patients among health care providers.

    2013-06-01

    Full Text Available Retroperitoneal fibrosis (RPF is a rare disease of unclear etiology, which is characterized by a chronic non specific inflammation of the retroperitoneum. This inflammation of the retroperitoneum may entrap and obstruct retroperitoneal structures, particularly the ureters. Patients with RPF show non specific clinical symptoms, including poorly localized back pain, general malaise, weight loss, anemia, features of renal failure and occasionally, mild fever. The early symptoms are non specific and an accurate diagnosis is often achieved only subsequent to urological obstruction or the occurrence of renal failure. Although a number of scientific journals devoted to RPF are present in the litera¬ture, there is no accepted diagnostic or therapeutic strategy for this disease. However, there are several therapeutic strate¬gies which have been proven to be effective. Hereby, we reported two cases of retroperitoneal fibrosis which had similar symptoms and findings but different responses to medical treatment .We aimed to discuss challanges of RPF%u2019s diagnosis and the treatment protocol.

    2008-05-01

    Full Text Available Abstract Introduction Spontaneous retroperitoneal hemorrhage is a distinct clinical entity that can present as a rare life-threatening event characterized by sudden onset of bleeding into the retroperitoneal space, occurring in association with bleeding disorders, intratumoral bleeding, or ruptures of any retroperitoneal organ or aneurysm. The spontaneous form is the most infrequent retroperitoneal hemorrhage, causing significant morbidity and representing a diagnostic challenge. Case presentation We report the case of a patient with coronary artery disease who presented with transient ischemic attack, in whom anticoagulant therapy with heparin precipitated a massive spontaneous atraumatic retroperitoneal hemorrhage (with international normalized ratio 2.4, which was treated conservatively. Conclusion Delay in diagnosis is potentially fatal and high clinical suspicion remains crucial. Finally, it is a matter of controversy whether retroperitoneal hematomas should be surgically evacuated or conservatively treated and the final decision should be made after taking into consideration patient's general condition and the possibility of permanent femoral or sciatic neuropathy due to compression syndrome.

    Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal...... sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referrals and diagnostic investigations were collected from clinical files from primary health care, local hospitals, and from the sarcoma centre. Lead times were divided into patient delays and health care...... at the general practitioner, 36 days at local hospitals, and 55 days at the sarcoma centre. Conclusion. Centralization per se is not sufficient for optimized and efficient management. Our findings suggest that delays can be minimized by direct referral of patients from primary health care to sarcoma centers...

  3. Type IV Ehlers-Danlos Syndrome: A Surgical Emergency? A Case of Massive Retroperitoneal Hemorrhage

    2011-01-01

    Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

    Background: Anabolic steroid intake is common among bodybuilders, although it is associated with a number of adverse effects, including tumorgenesis. Case Report: We describe the case of 24-year-old male athletic bodybuilder (weight 110 kg, height 179, BMI 34 kg/m 2 ) admitted to our department with diffused, intermittent, abdominal pain of 4 months duration. The patient had a history of long-term abuse of large doses of anabolic steroids of unknown origin. Computed tomography scans revealed a large, 140 x 100 mm, well-demarcated tumor, located between the left kidney, pancreas and spleen, presumably originating from the left kidney or adrenal gland. The tumor was proven to be hormonally inactive. Retroperitoneal tumor excision was performed with surrounding organs left intact. A final histopathologic examination revealed a well-differentiated 16 cm ganglioneuroma. Despite the rarity of its occurrence, ganglioneuromas must be considered in the differential diagnosis of retroperitoneal tumors. Conclusions: This unique finding raises questions concerning potential development of ganglioneuroma secondary to steroid abuse among bodybuilders. Bodybuilders should be made aware of the serious medical risks of steroid abuse. (authors)

    2009-01-01

    Purpose: To evaluate the applicability of carbon ion radiotherapy (CIRT) for unresectable retroperitoneal sarcomas with regard to normal tissue morbidity and local tumor control. Methods and Materials: From May 1997 to February 2006, 24 patients (17 male and 7 female) with unresectable retroperitoneal sarcoma received CIRT. Age ranged from 16 to 77 years (median, 48.6 years). Of the patients, 16 had primary disease and 8 recurrent disease. Histologic diagnoses were as follows: malignant fibrous histiocytoma in 6, liposarcoma in 3, malignant peripheral nerve sheath tumor in 3, Ewing/primitive neuroectodermal tumor (PNET) in 2, and miscellaneous in 10 patients. The histologic grades were as follows: Grade 3 in 15, Grade 2-3 in 2, Grade 2 in 3, and unknown in 4. Clinical target volumes ranged between 57 cm 3 and 1,194 cm 3 (median 525 cm 3 ). The delivered carbon ion dose ranged from 52.8 to 73.6 GyE in 16 fixed fractions over 4 weeks. Results: The median follow-up was 36 months (range, 6-143 months). The overall survival rates at 2 and 5 years were 75% and 50%, respectively. The local control rates at 2 and 5 years were 77% and 69%. No complications of the gastrointestinal tract were encountered. No other toxicity greater than Grade 2 was observed. Conclusions: Use of CIRT is suggested to be effective and safe for retroperitoneal sarcomas. The results obtained with CIRT were a good overall survival rate and local control, notwithstanding the fact that most patients were not eligible for surgical resection and had high-grade sarcomas.

    2012-01-01

    To describe a rare case of a retroperitoneal duplication cyst that fistulized to the vagina. Case description and discussion of a patient found to have an intestinal duplication cyst. A patient presented for a laparoscopic hysterectomy because of menorrhagia and a fibroid uterus. She also complained of recurrent urinary tract infections (UTIs) and a vaginal discharge. A retroperitoneal intestinal duplication cyst that fistulized to the vagina and caused her recurrent UTIs was identified. Surgical resection of the cyst resolved her complaint of recurrent UTIs. Retroperitoneal intestinal duplication cysts are rare congenital anomalies with vague clinical manifestations. The finding of a fistulous communication to the vagina originating from such a structure can be associated with recurrent UTIs.

    2014-05-01

    Soft tissue sarcomas are a group of heterogeneous neoplasms with more than 50 histological subtypes exhibiting major differences in terms of pathogenesis, genetic alterations and clinical behavior. Sarcomas represent approximately 1% of malignancies with retroperitoneal sarcomas representing 10-15% of all soft tissue sarcomas. Surgery is currently the only modality which offers the chance of cure. Surgery for retroperitoneal sarcomas presents specific challenges due their location in a complex space surrounded by vital structures and visceral organs often prohibiting resection with wide margins. Furthermore, even after complete resection local recurrence is common and the leading cause of death. In this article the authors describe the initial investigations, prognostic factors and optimal surgical management. The evidence and current research as regards the role of multimodality treatment is reviewed and discussed.

    Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

    2013-12-01

    Full Text Available Hydatid disease is one of the oldest diseases known to mankind. In 85-95% of the cases, the liver and/or the lung are involved and in only 5-15% the cyst occurs at the other sites. Echinococcal cysts are mostly found in the liver (60%-70% of cases, followed by the lungs (10%-25%, spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body. 1-3 Retroperitoneal location of hydatid cyst is encountered rarely and only occasional case reports have appeared since Lockhart and Sapinza first reported this entity in 1958. 4-6 Primary retroperitoneal hydatid cyst is extremely rare. Hydatid disease in extrahepatic locations usually remains asymptomatic unless the cyst grows and produces.

    Full Text Available Abscesses are a rare complication of transanal minimally invasive surgery and transanal endoscopic micro surgery. Reported cases have been in the rectal and pre-sacral areas and have been managed with either antibiotics alone or in conjunction with laparotomy and diverting colostomy. We report a case of a large retroperitoneal abscess following a Transanal minimally invasive surgery full thickness rectal polyp excision. The patient was successfully managed conservatively with antibiotics and a percutaneous drain.

    To understand the structure and character of the right retroperitoneal space by analysis of the extension of retroperitoneal hematoma in patients with traumatic right renal injuries. We retrospectively reviewed CT scans of 13 patients with right retroperitoneal hematomas caused by right renal injury. At te renal level, we analyzed the relation of a hematoma contacting psoas muscle with other retroperitoneal compartmental hematomas. At the suprarenal level, a perirenal hematoma and a hematoma contacting the diaphragm were analyzed according to their relation with intrahepatic IVC and pericaval hematoma. Below renal hilar level, all hematomas contacting psoas muscle, observed in eight cases, were connected with retrorenal extension of anterior pararenal hematoma. At the suprarenal level, intrahepatic pericaval hematomas were not, in all 13 cases, connected with a hematoma contacting the diaphragm, but with a perirenal hematoma. At the upper suprarenal level, the only pericaval hematomas containing a medial component of perirenal hematoma extended superiorly to the upper one third of the tenth thoracic vertebral body. The anterior renal fascia envelops perirenal space except in its medial aspect. In the upper suprarenal region, the anterior and posterior planes of the anterior renal fascia unite to fuse with diaphragmatic fascia, but along the medial aspect they fuse with intrahepatic pericaval connective tissue and posteromedial diaphragm, respectively

    Full Text Available Abstract Introduction Persistent lymphatic drainage following retroperitoneal lymph node dissection for testicular tumor is an uncommon complication. Case presentation We describe a 21-year old man of Caucasian origin who had metastatic non-seminomatous germ cell tumor of the testis, and underwent retroperitoneal lymph node dissection, nephrectomy and partial inferior vena cava excision for a residual mass. The patient subsequently developed persistent lymphatic drainage causing foot drop that eventually responded to conservative medical and surgical measures. Conclusion This postoperative condition usually responds well to conservative measures but has the potential for serious morbidity if it is not managed appropriately.

    Recently, the radiological concept of retroperitoneal interfascial planes has been widely accepted to explain the extension of retroperitoneal pathologies. This study aimed to explore embryologically based corroborative evidence, which remains to be elucidated, for this concept. Using serial or semi-serial transverse sections from 29 human fetuses at the 5th-25th week of fetal age, we microscopically observed the development of the retroperitoneal fasciae and other structures in the retroperitoneal connective tissue. A hypothesis for the formation of the interfascial planes was generated from the developmental study and analysis of retroperitoneal fasciae in computed tomography images from 224 patients. Whereas the loose connective tissue was uniformly distributed in the retroperitoneum by the 9th week, the primitive renal and transversalis fasciae appeared at the 10th-12th week, as previous research has noted. By the 23rd week, the renal fascia, transversalis fascia, and primitive adipose tissue of the flank pad emerged. In addition, the primitive lateroconal fascia, which runs parallel to and close to the posterior renal fascia, emerged between the renal fascia and the adipose tissue of the flank pad. Conversely, pre-existing loose connective tissue was sandwiched between the opposing fasciae and was compressed and narrowed by the developing organs and fatty tissues. Through this developmental study, we provided the hypothesis that the compressed loose connective tissue and both opposed fasciae compose the interfascial planes. Analysis of the thickened retroperitoneal fasciae in computed tomography images supported this hypothesis. Further developmental or histological studies are required to verify our hypothesis.

    Full Text Available Introduction. We retrospectively report our experience with the utilization of an original procedure for total laparoscopic hysterectomy based on completely retrograde and retroperitoneal technique for surgical staging and treatment of the endometrial cancer. The surgical, financial, and oncological advantages are here discussed. Methods. The technique used here has been based on a combination of a retroperitoneal approach with a retrograde and lateral dissection of the bladder and retrograde culdotomy with variable resection of parametrium. No disposable instruments and no uterine manipulator were utilized. Results. Intraoperative and postoperative complications were observed in 10% of the cases overall. Operative time length and mean haemoglobin drop value results were 129 min and 125 mL, respectively. Most patients were dismissed on days 3–5 from the hospital. Seventy-eight percent of the patients were alive with no evidence of disease at mean followup of 49 months. Conclusions. Our original laparoscopic technique is based on a retroperitoneal approach in order to rapidly control main uterine vessels coagulation, constantly check the ureter, and eventually decide type and site of lymph nodes removal. This procedure has important cost saving implications and the avoidance of uterine manipulator is of matter in case such as these of uterine malignancy.

    Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

    Patients with metastatic renal cell carcinoma have a reported 5-year survival of 0% to 20%. The ability to predict which patients would benefit from nephrectomy and interleukin-2 (IL-2) therapy before any treatment is initiated would be useful for maximizing the advantage of therapy and improving the quality of life. A retrospective analysis of the x-rays and charts of patients treated at the National Institutes of Health Surgery Branch between 1985 and 1996, who presented with metastatic renal cancer beyond the locoregional area and the primary tumor in place, was performed. Preoperative computerized tomography or magnetic resonance imaging, or radiological reports if no scans were available, were used to obtain an estimate of the volume of retroperitoneal lymphadenopathy. Operative notes were used to evaluate whether all lymphadenopathy was resected or disease left in situ, or if any extrarenal resection, including venacavotomy, was performed. Mean survival rate was calculated from the time of nephrectomy to the time of death or last clinical followup. If patients received IL-2 therapy, the response to treatment was recorded. Mean survival and response rate for IL-2 were compared among patients in 3 separate analyses. Patients without preoperatively detected lymphadenopathy were compared with those with at least 1 cm.3 retroperitoneal lymphadenopathy. Also, the patients who had detectable lymphadenopathy were divided into subgroups consisting of all resected, incompletely resected, unresectable and unknown if all disease was resected. Each subgroup was compared with patients without detectable preoperative lymphadenopathy. Patients with less than were compared to those with greater than 50 cm.3 retroperitoneal lymphadenopathy. Patients undergoing extrarenal resection at nephrectomy (complex surgery) due to direct invasion of the tumor into another intra-abdominal organ were compared with those undergoing radical nephrectomy alone, regardless of lymph node status

    Cystic lesions of the pancreas consist of a broad range of pathological entities. With the exception of the pancreatic pseudocyst, these are usually caused by pancreatic cystic neoplasms. Non-neoplastic pancreatic cystic and cystic-like lesions are extremely rare. In the present article, the surgical experience with these unusual entities over a 14-year period is reported. Between 1991 and 2004, all patients who underwent surgical exploration for a cystic lesion of the pancreas were retrospectively reviewed. Patients with a pancreatic pseudocyst were excluded. There were 106 patients of whom 8 (7.5%) had a final pathological diagnosis consistent with a non-neoplastic pancreatic cystic or cystic-like lesion, including 3 patients with a benign epithelial cyst, 2 with a pancreatic abscess (one tuberculous and one foreign body), 2 with mucous retention cysts and 1 with a mucinous non-neoplastic cyst. These eight patients are the focus of this study. There were six female and two male patients with a median age of 61.5 years (range, 41-71 years). All the patients were of Asian origin including seven Chinese and one Indian. Four of the patients were asymptomatic and their pancreatic cysts were discovered incidentally on radiological imaging for other indications. All the patients underwent preoperative radiological investigations, including ultrasonography, computed tomography or magnetic resonance imaging, which showed a cystic lesion of the pancreas. Three patients, all of whom were symptomatic, were diagnosed preoperatively with a malignant cystic neoplasm on the basis of radiological imaging. Two patients were eventually found to have a pancreatic abscess, one tuberculous and the other, secondary to foreign body perforation. The third patient was found on final histology to have chronic pancreatitis with retention cysts. The remaining five patients had a preoperative diagnosis of an indeterminate cyst; on pathological examination, they were found to have a benign

    Although using fine needle cytology with aspiration (FNC-A) for establishing diagnoses in the retroperitoneal region has shown promise, there is scant literature supporting a role of non-aspiration cytology (FNC-NA) for this region. We assessed the accuracy and reliability of FNC-A and FNC-NA as tools for preoperative diagnosis of retroperitoneal masses and compared the results of both techniques with each other and with histopathology. Fifty-seven patients with retroperitoneal masses were subjected to FNC-A and FNC-NA. Smears were stained with May-Grunwald Giemsa and hematoxylin and eosin stain. An individual slide was objectively analysed using a point scoring system to enable comparison between FNC-A and FNC-NA. By FNC-A, 91.7% accuracy was obtained in cases of retroperitoneal lymph node lesions followed by renal masses (83.3%). The diagnostic accuracy of other sites by FNC-A varied from 75.0%-81.9%. By FNC-NA, 93.4% diagnostically accurate results were obtained in the kidney, followed by 75.0% in adrenal masses. The diagnostic accuracy of other sites by FNC-NA varied from 66.7%-72.8%. Although both techniques have their own advantages and disadvantages, FNC-NA may be a more efficient adjuvant method of sampling in retroperitoneal lesions.

    Immunoglobulin G4 (IgG4)-related disease encompasses a wide variety of immune disorders previously thought be distinct. IgG4-related retroperitoneal fibrosis is one such entity. Metabolic imaging with 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) can be useful in the management of IgG4-related retroperitoneal fibrosis. We here discuss the case of 63-year-old male with IgG4-related retroperitoneal fibrosis and the role, 18 F-FDG PET/CT played in his management

    Retrograde ejaculation is a frequent and permanent complication after bilateral retroperitoneal lymphadenectomy (RPLND). Seminal emission and ejaculation are primarily under sympathetic control. Several studies after RPLND in patients with nonseminomatous testis cancer proved the role of preservation of the efferent fibers originating from the lumbar sympathetic ganglia. Based on the results of anatomical studies, a modified unilateral operative technique and nerve-sparing approach permit to preserve normal anterograde ejaculation without reduction of long-term survival.

    2012-02-01

    Full Text Available Abstract Introduction Retroperitoneal necrotizing fasciitis is a rare, fulminant, and potentially lethal complication of intra-abdominal suppuration. A retroperitoneal origin is very rare and very few cases have been reported in the literature. To the best of our knowledge, this case is only the fourth case reported of successful management following retroperitoneal necrotizing fasciitis. Case presentation A 33-year-old Tamang man presented to our facility with a history of five days of fever and vomiting and eight days of severe left loin pain. On examination, he had features of peritonism. A laparotomy was performed, revealing extensive necrotizing fasciitis of the retroperitoneum extending to the anterior abdominal wall. Our patient survived following extensive debridement of the necrotic tissues and supportive care. Conclusions Retroperitoneal necrotizing fasciitis can rarely present with features of peritonism, and hence should be included as a possible differential diagnosis for anyone presenting with peritonism. Although a fatal condition, early intervention and aggressive management can save the life of a patient.

    The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. Copyright © 2014 Elsevier Inc. All rights reserved.

    • To report our experience with retroperitoneal laparoscopic dismembered pyeloplasty for pelvi-ureteric junction (PUJ) obstruction in children. • Between March 2007 and December 2009, 38 children with PUJ obstruction (mean age 8.3 years, range 3-14) underwent retroperitoneal laparoscopic dismembered pyeloplasty. • A ureteric catheter was inserted into the mid-ureter cystoscopically. During pyeloplasty, the proximal end of the ureteric catheter was extracorporeally sutured to the distal end of the JJ stent with silk. • The ureteric catheter was then pulled down and the stent was pulled antegrade into the ureter and bladder. • The approach was retroperitoneal in all patients except one who required open conversion. The overall mean operative time was 162 min (range 145-210 min) and this appeared to decrease with experience. Mean hospital stay was 4 days (range 3-7 days). • Mean follow-up was 20.2 months (range 6-32 months). Satisfactory drainage with decreased hydronephrosis was documented in all patients on ultrasonography and intravenous urography. • Our study shows that retroperitoneal laparoscopic dismembered pyeloplasty is a feasible and effective alternative to open pyeloplasty with a relatively minimal complication rate in children 3 years of age and older, but it should be undertaken by experienced laparoscopic surgeons. © 2011 THE AUTHORS.

    Optional inferior vena cava (IVC) filters are being increasingly used for protection against pulmonary embolism in patients with deep vein thrombosis where anticoagulation is contraindicated. We describe two cases during retroperitoneal surgery where the IVC filters were found to have perforated the cava wall and were subsequently removed intra-operatively. Cava wall penetration by filter limbs poses a significant danger during retroperitoneal lymph node dissection and filters should be removed preoperatively.

    Full Text Available Introduction. Adrenal hemangioma is a rare disease, with only some 60 cases reported previously. Due to the difficulty of the preoperative diagnosis of adrenal hemangioma, almost all of the cases were diagnosed by a histopathological analysis of surgical specimens. Case Presentation. A 52-year-old man was referred to our department for further examination of his left retroperitoneal tumor. He had received hemodialysis due to chronic renal failure resulting from membranous nephropathy. Computed tomography revealed a mass around his left hilum. Magnetic resonance imaging (MRI and positron-emission tomography (PET-CT were unable to confirm or deny malignancy, and tumor markers, including CEA and CA19-9, showed slight elevation. His tumor grew from 38 mm to 54 mm in diameter in 7 months of follow-up. We therefore planned retroperitoneal tumor resection with left nephrectomy. Histopathologically, hyperplastic small vessels with hemorrhaging and denaturation were seen. The endothelial cells showed no variants or division of the nucleus. Based on this diagnosis, no further therapy was performed. He has had no recurrence in the eight months since the surgery. Conclusion. We herein report a rare case of adrenal hemangioma.

    2008-07-01

    An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

  20. Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

    2014-01-01

    IgG4-related autoimmune pancreatitis is frequently accompanied by relevant lesions in the genitourinary tract and retroperitoneal organs, which cause various clinical problems, ranging from non-specific back pain or bladder outlet obstruction to renal failure. The diagnosis of IgG4-related retroperitoneal fibrosis requires a multidisciplinary approach, including serological tests, histological examination, imaging analysis, and susceptibility to steroid therapy. Radiological examinations are helpful to diagnose this condition, but surgical resection is occasionally unavoidable to exclude malignancy, particularly for patients with isolated retroperitoneal involvement. Steroid therapy is the treatment of choice for this condition, the same as for other manifestations of IgG4-related disease. For patients with severe ureteral obstruction, additional ureteral stenting needs to be considered prior to steroid therapy to preserve the renal function. Some papers have suggested that IgG4-related disease can affect male reproductive organs including the prostate and testis. IgG4-related prostatitis usually causes lower urinary tract symptoms, such as dysuria and pollakisuria. Patients sometimes state that corticosteroids given for IgG4-related disease at other sites relieve their lower urinary tract symptoms, which leads us to suspect prostatic involvement in this condition. Because of the limited number of publications available, further studies are warranted to better characterize IgG4-related disease in male reproductive organs. PMID:25469023

  1. Retroperitoneal unicentric Castleman's disease (giant lymph node hyperplasia: case report

    Jaques Waisberg

    Full Text Available CONTEXT AND OBJECTIVE: Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's disease in the retroperitoneum. CASE REPORT: A 61-year old white male with weight loss and listlessness presented with moderate arterial hypertension and leukopenia. Abdominal tomography revealed a 5 x 4 x 5 cm oval mass of low attenuation, with inner calcification and intense enhancement on intravenous contrast, located in the retroperitoneal region, between the left kidney and the aorta, at the renal hilus. Exploratory laparotomy revealed a non-pulsatile solid oval mass situated in the retroperitoneum, adjacent to the left renal hilus. The retroperitoneal lesion was removed in its entirety. Examination of frozen samples revealed benign lymph node tissue and histopathological examination of the surgical sample revealed hyaline-vascular giant lymph node hyperplasia (Castleman's disease. The patient was discharged on the 12th day without significant events. Two months after the operation, the patient was readmitted with severe cardiac insufficiency, acute renal failure and bronchopneumonia, which progressed to acute respiratory insufficiency, sepsis and death.

    Full Text Available Intra-abdominal infection due to Chryseobacterium meningosepticum is rare, and bacteremia complicated with pleural effusion and retroperitoneal hematoma caused by C. meningosepticum has not been reported previously. A 57-year-old diabetic man presented with bacteremia with retroperitoneal abscess and pleural effusion caused by C. meningosepticum on the 12th day of hospitalization. His clinical condition improved after antimicrobial therapy with levofloxacin and rifampin, debridement of the retroperitoneal hematoma and left-side chest tube insertion. Antibiotics were administered for 1 month, and he was later transferred to a local respiratory care ward under afebrile condition. C. meningosepticum should be included in the list of suspected nosocomial infections, especially in patients with immunocompromised status. Administration of appropriate antibiotics, such as quinolone, minocycline, trimethoprim-sulfamethoxazole or rifampin, and treatment of local infection improve the clinical outcome of patients with C. meningosepticum infection.

    There are very few published reports implicating enoxaparin as a factor in retroperitoneal hematoma. We report a patient who developed a retroperitoneal hematoma after using enoxaparin for paroxysmal atrial fibrillation. A 72 year old man was admitted with a history of low back pain, radiating beyond the back to the buttocks. His medical history was positive for bilateral knee osteoarthritis. On his physical examination his vital signs were: temperature 36.8, blood pressure 100/70 mm Hg, pulse 72/min, respiratory rate 16/min. X-ray of both the knees showed bilateral osteoarthritic changes. Computerized tomography scan of the spine showed lumbar spinal stenosis and he was referred to a Neurosurgeon, who finds the patient not fit surgical intervention. ECG showed atrial fibrillation. He was given enoxaparin one mg/kg every 12 hour and digoxin. Abdominal computed tomography revealed a right retroperitoneal hematoma and no aortic aneurysm was noted and enoxaparin and rofecoxib were discontinued. His general condition improved. The factors that increase the risk of bleeding in patients receiving enoxaparin are use of high doses of enxaparin, advanced stage, renal impairment, and the concomitant use of drugs affecting hemostasis. Retroperotoneal hematoma should be considered in the different diagnosis in patients receiving enoxaparin and experiencing unexplained decreases in hemoglobin and hematocrit. In the order of precedence of radiologic diagnostic procedures for fast diagnosis of a retroperitoneal hematoma, abdominal CT-scan is the preferred method

    Surgery is potentially curative for primary non-metastatic retroperitoneal soft tissue sarcomas (RPS), although patients remain at risk for local recurrence. To reduce this risk, the addition of radiotherapy to radical surgery may be considered. Nevertheless, level I evidence to support radiotherapy is currently lacking. The results from the EORTC-STBSG 62092-22092 studying this question are awaited. This manuscript addresses issues to consider when radiation-oncologists engage in a multidisciplinary treatment approach for RPS patients, including radiotherapy. © 2017 Wiley Periodicals, Inc.

    Objective: To investigate the clinical significance of peritoneal and retroperitoneal edema in patients with de-compensated cirrhosis (DCC). Methods: Forty-four patients, were identified with DCC on the basis of clinic and laboratory examinations, except the cases with mesenteric, omental and retroperitoneal edema caused by inflammatory and malignant diseases. The diagnosis of edema depended upon hyper-density in peritoneal and retroperitoneal. The degree of edema was divided into minor, middle, and sever types based on the extent of edema. Ascites, varices, serum albumin (ALB) levels, and hyaluronic acid (HA) levels were also documented. Correlations between the laboratory and CT findings were analyzed. Results: The severity of peritoneal edema was correlated with decreasing serum ALB (r s = 0.7088, P s = 0.5294, P s = 0.5440, P s = 0.1335, P > 0.05). Conclusion: CT findings of the edema in peritoneal and retroperitoneal may indicate the severity of the liver cirrhosis

    Retroperitoneal fibrosis (RPF) is a rare condition of unclear etiology. It can cause ureteral obstruction. We present the unique case of a 54 years old female, who initially presented with spontaneous perforation of the cecum. Upon exploring the abdomen, the classical glistening white, unyielding retroperitoneal fibrosis was encountered. A right hemicolectomy was performed.Subsequently, the patient presented with bilateral ureteral obstruction, and later on with small bowel obstruction. Ureteral obstruction was treated with stents,and small bowel obstruction was treated with bypass.To our knowledge no case of idiopathic RPF presenting with features of both bilateral ureteral and small bowel obstruction has been reported in the literature.

  17. Management of metastatic retroperitoneal sarcoma: a consensus approach from the Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG).

    Science.gov (United States)

    2018-04-01

    Retroperitoneal sarcoma (RPS) is a rare disease accounting for 0.1%-0.2% of all malignancies. Management of RPS is complex and requires multidisciplinary, tailored treatment strategies at all stages, but especially in the context of metastatic or multifocal recurrent disease. Due to the rarity and heterogeneity of this family of diseases, the literature to guide management is limited. The Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG) is an international collaboration of sarcoma experts from all disciplines convened in an effort to overcome these limitations. The TARPSWG has compiled the available evidence surrounding metastatic and multifocally recurrent RPS along with expert opinion in an iterative process to generate a consensus document regarding the complex management of this disease. The objective of this document is to guide sarcoma specialists from all disciplines in the diagnosis and treatment of multifocal recurrent or metastatic RPS. All aspects of patient assessment, diagnostic processes, local and systemic treatments, and palliation are reviewed in this document, and consensus recommendations provided accordingly. Recommendations were guided by available evidence, in conjunction with expert opinion where evidence was lacking. This consensus document combines the available literature regarding the management of multifocally recurrent or metastastic RPS with the practical expertise of high-volume sarcoma centers from multiple countries. It is designed as a tool for decision making in the complex multidisciplinary management of this condition and is expected to standardize management across centers, thereby ensuring that patients receive the highest quality care.

    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

    Recently accompanying the development of engineering technology, huge systems tend to be constructed. The disaster countermeasures of huge cities become large problems as the concentration of population into cities is conspicuous. To make the expected value of loss small, the knowledge of reliability engineering is applied. In reliability engineering, even if a part of structures fails, the safety as a whole system must be ensured, therefore, the design having margin is carried out. The degree of margin is called redundancy. However, such design concept makes the structure of a system complex, and as the structure is complex, the possibility of causing human errors becomes high. At the time of huge system design, the concept of fail-safe is effective, but simple design must be kept in mind. The accident in Mihama No. 2 plant of Kansai Electric Power Co. and the accident in Chernobyl nuclear power station, and the accident of Boeing B737 airliner and the fatigue breakdown are described. The importance of safety culture was emphasized as the method of preventing human errors. Man-system interface and management system are discussed. (K.I.)

    Patients with a primary pure seminoma in the testis who have elevated serum alpha-fetoprotein are rare and should be treated as patients with nonseminomatous germ cell tumors. However, nonpalpable testicular tumors in this condition have never been reported. We describe a case of nonpalpable pure testicular seminoma with elevated serum alpha-fetoprotein presenting retroperitoneal metastasis. A 29-year-old Asian man was referred to our hospital with right flank pain. Computed tomography showed a mass located between his aorta and inferior vena cava, but a testicular tumor was not detected. His serum levels of lactate dehydrogenase, alpha-fetoprotein, and DUPAN-2 were high. Although no tumor or nodule was palpable in his testis, ultrasonography revealed multiple low echoic lesions in his right testicular parenchyma. He was diagnosed with right testicular cancer with retroperitoneal lymph node metastasis and underwent right high orchiectomy. A pathological examination revealed pure seminoma and no nonseminomatous components were found in the specimen. Three courses of induction systemic chemotherapy (cisplatin, etoposide, and bleomycin) normalized his serum alpha-fetoprotein and DUPAN-2 levels. Three additional courses of chemotherapy (etoposide and bleomycin) were performed, and treatment was completed with laparoscopic retroperitoneal lymph node dissection. Pathology of the dissected specimen showed fibrous and necrotic tissue with no viable cells. He is alive without recurrence 54 months after orchiectomy. We report a case of pure testicular seminoma with elevated serum alpha-fetoprotein and DUPAN-2 presenting retroperitoneal metastasis. We recommend an ultrasound examination of bilateral testes when large retroperitoneal tumors are detected in young men, even if a mass is not palpable in the scrotum.

    The purpose of this study was to introduce a new method for locating the renal artery during retroperitoneal laparoscopic renal surgery. The medial arcuate ligament (MAL) is a tendinous arch in the fascia under the diaphragm that arches across the psoas major muscle and is attached medially to the side of the first or the second lumbar vertebra. The renal artery arises at the level of the intervertebral disc between the L1 and L2 vertebrae. We evaluate the role of the MAL that serves as an anatomic landmark for locating the renal artery during retroperitoneal laparoscopic renal surgery. There is a reproducible consistent anatomic relationship between MAL and the renal artery in 210 cases of retroperitoneal laparoscopic renal surgery. Two main types of the MAL, the "narrow arch" and the "fascial band" types, can be observed. MAL can serve as an accurate and reproducible anatomic landmark for the identification of the renal artery during retroperitoneal laparoscopic renal surgery.

    Malignant nerve sheath tumours (MPNST) are rare neoplasias and retroperitoneal cases are fairly rare and clinically difficult to be detected, but they are very agressive neoplasias. MPNST are frequently seen in head, neck and upper extremities. In patients with NF1; MPNST, a poor-prognostic lesion, may result from a malignant degeneration of a former plexiform neurofibroma. It is necessary to be aware of a potential malignancy in patients diagnosed with plexiform neurofibroma. We present a 21-year-old female with a diagnosis of MPNST. The patient was admited to the hospital because of a tumour in the subcutaneous region on her left buttock. The surgeon's clinical diagnosis was lipoma. After the pathological examination of biopsy specimen, the lesion was identified as "plexiform neurofibroma" and then the patient was diagnosed with Neurofibromatosis Type 1 (NF1). Simultaneously, another mass on the retroperitoneal region was identified as malignant peripheral nerve sheath tumour (MPNST).

    We report three cases of atypical retroperitoneal sarcomas: leiomyosarcoma, embrionary rhabdomyosarcoma and malignant peripheral nerve sheath tumor (previously known as neuro sarcoma and neuro fibrosarcoma). These lesions, which are characterized by large and heterogeneous retroperitoneal masses, are uncommon and usually diagnosed late. Intravenous contrast enhanced computerized tomography is a useful method for the evaluation of these tumors and their relationship with adjacent structures. (author)

    Although retro-peritoneal hematoma accompanying a pelvic fracture has been treated by arterial ligation formerly, it is associated with a high mortality rate and a transcatheter arterial embolization has now become the first choice of treatment. Meanwhile, the usefulness of computed tomography (CT) in traumatized patient has been reported frequently. Our hospital also employs CT positively as an examination following plain radiography in the cases with pelvic fracture. However, while indication of angiography is seen in several reports, the amount of retro-peritoneal hematoma as an index has not been reported. In the present study, we examined 112 patients given CT at the time of examination at the emergency center of our hospital between April 1, 1988, and June 30, 1997, and classified the amount of retro-peritoneal hematoma on CT into 5 groups to discuss indication of angiography. In the cases with moderate or massive amount of retro-peritoneal hematomas, cases with shock state exceeded 60% and the amount of hematoma was considered to reflect the circulation profile to a certain extent. As the amount of retro-peritoneal hematoma increased, the number of cases given embolization also increased; embolization was performed in 29 cases (61.7%) among those which had moderate or massive amount of hematoma. From the above findings, it was predicted that the amount of retro-peritoneal hematoma could be one of the deciding factors for indication of angiography. However, as there are cases falling into a shock state due to gradual increase of hematoma or associated with injuries in other organs, careful observation is needed for the cases judged out of indication.

    In this pictorial essay we present the typical appearances of cystic pancreatic tumours, the wide spectrum of their features, and differential features among cystic pancreatic masses with an emphasis on CT. Pseudocysts are the most common cystic lesion in the pancreas and can be induced by pancreatitis, trauma or surgery. Pseudocysts appear as a round cystic mass with a definite wall. However, they can mimic cystic tumours associated with internal septation and/or necrotic mass of various shapes. Conversely, cystic tumours can appear as a simple cyst lacking any thickening of wall, septation or mural nodule. Pancreatic carcinoma not infrequently induces secondary cysts upstream of the obstructed pancreatic duct. The cysts are pseudocysts or retention cysts in nature. When cysts are formed in the pancreatic parenchyma or adjacent to pancreatic carcinoma they may mimic cystic tumour. (orig./VHE)

    Hydronephrosis is a common disease in children and may be caused by ureteral fibroepithelial polyps (UFP). Ureteral fibroepithelial polyps are rare in children and are difficult to precisely diagnose before surgery. Surgical treatment for symptomatic UFP is recommended. At the present institution, retroperitoneal laparoscopy has been used to treat five boys with UFP since 2006. To highlight the significance of UFP as an etiological factor of hydronephrosis in children and evaluate the applicative value of retroperitoneal laparoscopy in the treatment of children with UFP. Between 2006 and 2013 five boys underwent retroperitoneal laparoscopy at the present institution. They were identified with UFP by review of the clinical database. Detailed data were collected, including: radiographic studies, gross anatomical pathology, and pathology and radiology reports. All boys had been followed up at least every 6 months. All of the boys were aged between 7 and 16 years (mean 9.8 years). The main symptoms were flank pain (all five) and hematuria (three). Radiographic examination showed that all of the boys presented with incomplete ureteral obstruction and hydronephrosis. The ureteral fibroepithelial polyps were located near the left UPJ or the left proximal ureter. All of the boys had the UFP removed: three underwent retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty and polypectomy, and two had retroperitoneal laparoscopic ureteral anastomosis. These polyps were all on the left side and between 15 and 35 mm in length (mean 22 mm) (Figure). All of the boys recovered well and were discharged from hospital. The postoperative histological report confirmed that the specimens were UFP. Hydronephrosis was periodically assessed by ultrasonography (using the same method as pre-surgical ultrasonography) after surgery. Mean follow-up was 33 months (range 6-58 months) and no complications were found afterwards. Ureteral fibroepithelial polyps are rare but rather

    The purpose of this study was to investigate retrospectively the clinical procedural performance of CT-guided needle biopsy for retroperitoneal lesions. CT-guided needle biopsy was performed in 74 consecutive patients (M:F = 44:30; mean age, 59.7 years) with retroperitoneal lesions between April 1998 and June 2009. The target lesion ranged from 1.5 to 12.5 cm in size. The biopsy access path ranged from 3.5 to 11.5 cm in depth. A biopsy specimen was obtained using an 18-gauge core needle under a CT or CT-fluoroscopy guidance and with the patient under local anesthesia. The histopathological diagnoses from the biopsies were obtained. The diagnostic confirmation of the subtype of lymphoma was evaluated. Satisfactory biopsy samples were obtained in 73 (99%) of 74 patients and a pathological diagnosis was made in 70 (95%) of 74 patients. Sixty three lesions were malignant (45 lymphomas, nine primary tumors, nine lymph node metastases) and seven were benign. The subtype of lymphoma was specified in 43 (96%) of 45 patients who were diagnosed with lymphoma. Analysis of the value of CT-guided biopsy in this series indicated 63 true positives, zero false positive, six true negatives and five false negatives. This test had a sensitivity of 93%, a specificity of 100% and an accuracy of 93%. No major complications were seen and minor complications were noted in seven patients (five with local hematomas, two with transient pain at the puncture site). CT-guided needle biopsy for retroperitoneal lesions is highly practical and useful, and particularly for determining the subtypes in patients with lymphoma.

    The purpose of this study was to evaluate the safety and precision of MRI-guided biopsies of retroperitoneal space-occupying tumors in an open low-field system. In 30 patients with indistinct retroperitoneal tumors [paraaortic lesion (n=20), kidney (n=2), suprarenal gland (n=3) and pancreas (n=5)] MR-guided biopsies were performed using a low-field system (0.2 T, Magnetom Concerto, Siemens, Germany). For the monitoring of the biopsies T1-weighted FLASH sequences (TR/TE=160/5 ms; 90 ) were used in all patients and modified FLASH sequences (TR/TE=160/13 ms; 90 ) in ten patients. After positioning of the needle in the tumors 114 biopsy specimens were acquired in coaxial technique with 16-gauge cutting needles (Somatex, Germany). The biopsies were successfully performed in all patients without vascular or organ injuries. The visualization of the aortic blood flow with MRI facilitated the biopsy procedures of paraaortic lesions. The size of the lesions ranged from 1.6 to 7.5 cm. The median distance of the biopsy access path was 10.4 cm. Adequate specimens were obtained in 28 cases (93.3%) resulting in a correct histological classification of 27 lesions (90%). In conclusion, MR-guided biopsies of retroperitoneal lesions using an open low-field system can be performed safely and accurately and is an alternative to CT-guided biopsies. (orig.)

    BACKGROUND: Ganglioneuroma is a rare tumour of neural crest origin, which arises from maturation of a neuroblastoma. While previously considered to be non-functioning, they are now known to be frequently endocrinologically active. AIMS AND METHODS: We report a case of a massive retroperitoneal ganglioneuroma presenting with small bowel obstruction in an adult, 18 years after initial diagnosis. Urinary dopamine levels were elevated, but other catecholamines were within normal limits. This is the first report in the English-language literature of a retroperitoneal ganglioneuroma presenting with or causing intestinal obstruction. We also review the metabolic, radiological, and histological features of these tumours. Relevant publications were identified from a Medline search using the MeSH headings \\'ganglioneuroma\\

    Herein we report a case of retroperitoneal amyloidoma in a 56-year-old man and to describe its imaging findings and pathologic features. Abdomen computed tomography showed multiple nodular masses with amorphous calcifications in the retroperitoneum. On histologic review, these masses were composed of extensive nodular deposition of irregularly shaped amorphous eosinophilic material that was strongly positive on Congo red staining and apple green birefringence under polarizing microscopy, which is diagnostic for amyloidosis.

    Aim: To determine the sensitivity of magnetic resonance imaging (MRI) in the detection of retroperitoneal lymph nodes in patients with testicular germ cell tumours (TGCT). Methods and materials: A prospective study of 52 patients (mean age 34 years, range 18-54 years) was performed. Imaging of the retroperitoneum was performed using multidetector computed tomography (CT) and 1.5 T MRI systems. The CT and MRI images were read independently by three observers. The number, size, and site of enlarged nodes ({>=}10 mm maximum short axis diameter) were recorded. Retroperitoneal nodal detection on MRI was compared to CT. Results: Twenty-two (42%) of the 52 patients had no retroperitoneal disease; in remaining 30 patients 51 enlarged nodes were identified. On a per patient basis readers 1, 2, and 3 identified nodal disease in 28 of 29, 29 of 30, and 24 of 30 patients, respectively, using MRI compared to CT. Thus for experienced radiologists (readers 1 and 2) MRI is comparable to CT for nodal detection (i.e., this study excludes MRI being inferior to CT with 80% power and 5% type 1 error). Conclusion: MRI offers an alternative method for staging the retroperitoneum in young patients being followed for TGCT and has the major advantage of avoiding exposure to ionizing radiation.

    To present our single-center experience with retroperitoneal laparoscopic partial nephrectomy (LPN) and retroperitoneal laparoscopic radical nephrectomy (LRN) for T1 renal hilar tumors and evaluate which one is better. A retrospective review of 63 patients with hilar tumors undergoing retroperitoneal LPN or LRN was performed. The perioperative characteristics, change in estimated glomerular filtration rate (eGFR) from baseline to month 3, and oncologic outcomes were summarized. In total, 25 patients underwent LPN, and 38 patients underwent LRN. The mean tumor size in the LPN and LRN groups was 4.5 and 4.9 cm, respectively. The mean operation time was longer in the LPN group than that in the LRN group (212.5 minutes versus 160.7 minutes, respectively; P  .05). In experienced hands, although retroperitoneal LRN can result in shorter operation times and shorter lengths of stay, retroperitoneal LPN can preserve renal function better than LRN. Retroperitoneal LPN should be the priority in selected patients with T1 renal hilar tumors, especially for patients with renal insufficiency.

    Full Text Available Background. Postpartum haemorrhage from ruptured tissues can usually be diagnosed and managed properly. A problem exists with the occult haemorrhage without evident tissue trauma in which case a haematoma develops. Methods. After a normal delivery of the 41 years old secundipara after a previous caesarean in epidural analgesia a boy was born. Placenta was delivered spontaneously and perineal rupure sutured properly. About an hour after the delivery heavy pain was noted in the lower abdomen. Pelvic exam revealed a paravaginal haematoma and ultrasound scan coagulated and fresh blood behind the uterus. Rupture of the uterus was suspected and laparotomy revision performed. During the laparotomy there was no haemorrhage in the pelvic cavity, no uterine rupture but a large retroperitoneal haematoma extending to mesosigmoidal part of intestinum. Paravaginal heamatoma was evacuated vaginally and after half an hour the retroperitoneal haematoma diminished by 50 %. The patient received two blood transfusions. The blood loss was estimated as about 500 grams. The pulse and blood pressure were normal all the time. The laboratory values of haemoglobin was 96 g/l, haematocrit 0.30 before the operation and 93 g/l and 0.28 respectively 6 hours after. Beside anaemia the postoperative course was uneventful and the patient was dismissed from the hospital the 6th day postpartum. Conclusions. Although the laparotomy seems an excessive treatment it was the only way to exclude uterus rupture after a previous caesarean, heavy pain in the lower abdomen and blood behind the uterus noted on the ultrasound scan. In the non-urgent situation a CT scan could be performed to locate the blood accumulation and possibly exclude uterine rupture.

  20. Connecting slow earthquakes to huge earthquakes.

    Slow earthquakes are characterized by a wide spectrum of fault slip behaviors and seismic radiation patterns that differ from those of traditional earthquakes. However, slow earthquakes and huge megathrust earthquakes can have common slip mechanisms and are located in neighboring regions of the seismogenic zone. The frequent occurrence of slow earthquakes may help to reveal the physics underlying megathrust events as useful analogs. Slow earthquakes may function as stress meters because of their high sensitivity to stress changes in the seismogenic zone. Episodic stress transfer to megathrust source faults leads to an increased probability of triggering huge earthquakes if the adjacent locked region is critically loaded. Careful and precise monitoring of slow earthquakes may provide new information on the likelihood of impending huge earthquakes. Copyright © 2016, American Association for the Advancement of Science.

    Full Text Available BACKGROUND: Retroperitoneal lipoma is an extremely rare neoplasm. AIMS: The authors report a case of giant retroperitoneal lipoma in a 32-year-old white female, with a history of pain and an abdominal mass over a 2-year period. Total abdominal ultrasonography and barium enema showed a large mass located in the retroperitoneal space behind the ascending colon. Laparotomy showed a large encapsulated tumor measuring 20 x 13 x 10 cm and weighing 3.400 g. The histological study revealed a benign neoplasm of fatty cells. CONCLUSION: The patient remains well 17 years after surgery, without recurrentce of the disease.RACIONAL: O lipoma é a neoplasia mesenquimal mais freqüente, raramente localizada no retroperitônio. Na maioria das vezes, o diagnóstico diferencial pré-operatório com os lipossarcomas de baixo grau de malignidade é difícil de ser estabelecido. OBJETIVO: Apresentar um caso de lipoma gigante retroperitoneal em mulher de 32 anos que há 2 anos apresentava história de dor e tumor abdominal palpável. A ultra-sonografia abdominal e o enema opaco mostraram grande massa localizada no retroperitônio, que deslocava o ceco e o cólon ascendente. A laparotomia mostrou tumor encapsulado com 20 x 13 x 10 cm e 3.400 g de peso. O estudo histopatológico mostrou presença de lipoma retroperitonial. A paciente encontra-se bem, sem recidiva da doença, 17 anos após a cirurgia.

    A 70-year-old man was diagnosed with retroperitoneal fibrosis (RPF) complicated by ureteral obstruction 4 months after finishing radiotherapy for prostate cancer. He was treated conservatively with ureteral stent placement. After 3 months, computed tomography scan of the abdomen revealed resolution of RPF without any medical or surgical interventions. Although an uncommon event, the possibility of spontaneous resolution of RPF, as demonstrated by this and previously reported cases, has led some to encourage conservative management.

    Purpose: Local failure is frequent after conventional therapy for patients with retroperitoneal sarcomas. A Phase I/II multimodality approach was used, combining iododeoxyuridine (IdUrd) and radiation therapy, followed by attempted surgical resection, with the goal of improving local control. Methods and Materials: Patients with retroperitoneal sarcomas were treated with three to five consecutive cycles of treatment. Each 14-day cycle consisted of a continuous intravenous infusion of IdUrd on days 1-5, twice a day radiation therapy (1.25 Gy/fraction) on days 8-12, and a break on day 13 and 14. Surgical resection was attempted after three or five cycles. Patients resected after three cycles received an additional two cycles of treatment with radiation directed to the tumor bed. IdUrd dose was escalated in Phase I fashion (1000 mg/m 2 /day, 1333 mg/m 2 /day, and 1600 mg/m 2 /day). The median potential follow-up was 31 months. Results: Sixteen patients (13 with high grade tumors) were treated. The median maximum tumor size was 17 cm. Resection margins were negative in four patients, microscopically positive in four patients, and grossly positive in three patients. Five patients were not resected. The only grade 4 acute toxicity observed was vomiting which occurred in three patients receiving upper abdominal radiation. Postsurgical and long-term complications were rare. Median survival overall and for resected patients were 18 and 32 months, respectively. Local control was observed in three out of four patients with negative margins (9, 40+, and 51+ months), two out of four patients with microscopically positive margins (4 and 22 months), and one out of three patients with grossly positive margins (46+ months). The overall freedom from local progression was 45% at 24 months. Conclusion: Retroperitoneal sarcomas can be resected after preoperative radiation therapy and IdUrd, with encouraging local control in patients resected with negative or microscopically positive

    To perform a bicenter, retrospective study of perioperative outcomes of retroperitoneal versus transperitoneal robotic-assisted laparoscopic partial nephrectomy (RALPN) and assess costs using time-driven activity-based costing (TDABC). We identified 355 consecutive patients who underwent RALPN at University of California Los Angeles and the University of Michigan during 2009-2016. We matched according to RENAL nephrometry score, date, and institution for 78 retroperitoneal versus 78 transperitoneal RALPN. Unadjusted analyses were performed using McNemar's Chi-squared or paired t test, and adjusted analyses were performed using multivariable repeated measures regression analysis. From multivariable models, predicted probabilities were derived according to approach. Cost analysis was performed using TDABC. Patients treated with retroperitoneal versus transperitoneal RALPN were similar in age (P = 0.490), sex (P = 0.715), BMI (P = 0.273), and comorbidity (P = 0.393). Most tumors were posterior or lateral in both the retroperitoneal (92.3%) and transperitoneal (85.9%) groups. Retroperitoneal RALPN was associated with shorter operative times (167.0 versus 191.1 min, P = 0.001) and length of stay (LOS) (1.8 versus 2.7 days, P factoring in disposable equipment, operative time, LOS, and personnel. In two high-volume, tertiary centers, retroperitoneal RALPN is associated with reduced operative times and shortened LOS in posterior and lateral tumors, whereas sharing similar clinicopathologic outcomes, which may translate into lower healthcare costs. Further investigation into anterior tumors is needed.

    This personal series of 44 primary retroperitoneal masses (P.R.P.M.) studied by C.T. is analyzed. The reliability of C.T. in the identification (44/44), characterization (43/44) and origin evaluation (41/44) of P.R.P.M. has been absolutely satisfactory. In particular, those criteria of C.T. diagnosis which may be utilized in the evaluation of the origin of upper abdominal masses are thoroughly described. The evaluation of the involvement (non invasive; invasive) of adjacent viscera has been achieved in 22/38 P.R.P.M. verified at operation. The evaluation of tumour resectability has been less reliable due to the high incidence of under-diagnosis (60% in our personal experience). C.T. may be used in addition as an aid to different diagnostic techniques (percutaneous guided needle biopsy) or to therapy (drainage of retroperitoneal abscesses). C.T. is absolutely necessary in the follow-up of P.R.P.M. after surgery, radiotherapy or chemotherapy.

    2015-02-01

    The authors present the first reported use of the lateral retroperitoneal transpsoas approach for interbody arthrodesis in a patient with achondroplastic dwarfism. The inherent anatomical abnormalities of the spine present in achondroplastic dwarfism predispose these patients to an increased incidence of spinal deformity as well as neurogenic claudication and potential radicular symptoms. The risks associated with prolonged general anesthesia and intolerance of significant blood loss in these patients makes them ideal candidates for minimally invasive spinal surgery. The patient in this case was a 51-year-old man with achondroplastic dwarfism who had a history of progressive claudication and radicular pain despite previous extensive lumbar laminectomies. The lateral retroperitoneal transpsoas approach was used for placement of interbody cages at L1/2, L2/3, L3/4, and L4/5, followed by posterior decompression and pedicle screw instrumentation. The patient tolerated the procedure well with no complications. Postoperatively his claudicatory and radicular symptoms resolved and a CT scan revealed solid arthrodesis with no periimplant lucencies.

    2003-01-01

    Purpose: To describe de imaging features of this unusual localization of Castleman's disease. Materials and methods: Two patients (man: 62 years old, woman: 27 years old) with epigastric abdominal pain were studied. The physical examination was negative in the woman while in the other case a peri umbilical tumor was observed. The laboratory and the tumor markers were negative. Both patients had a history of appendectomy. US, TC and MRI were performed. After surgery the pathological examination included stain techniques with hematoxylin-eosin, Masson's techniques and PAS. Results: Retroperitoneal Castleman's disease in peri pancreatic localization (extremely rare). The US showed slight hypoechoic homogeneous lesions with clear rims. CT without contrast revealed isodense lesions and one of them presented a small calcification, the e.v. contrast CT showed a clear homogeneous reinforcement. MRI demonstrated hypointense lesions on T1, hyperintense on T2, and after the administration of gadolinium these lesions showed a marked reinforcement on the arterial phase, which persisted on the late venous phase. The differential diagnosis with pancreatic tumoral pathology was difficult. The pathological examination revealed a lymphoid angio follicular hyperplasia of hyaline vascular type. Conclusion: Retroperitoneal Castlelman's disease is a rare entity. The different imaging methods did not provide an accurate diagnosis of this entity since there are no pathognomonic features. The pathological examination was required to define the diagnosis in both reported cases. (author)

  10. Localized bilateral perirenal fibrosis, a rare cause of idiopathic retroperitoneal fibrosis

    2014-08-01

    Full Text Available Background: Idiopathic retroperitoneal fibrosis is an infrequent process of unknown aetiology characterised by fibrous tissue proliferation in the retroperitoneum. Even less frequent is a localized form of this disease by a proliferation of fibrous tissue around single or both kidneys.Case report: We describe a case of 46-year old man in whom medical management was started for accidentally discovered arterial hypertension, which turned out to be difficult to control.   During diagnostic work-up of hypertension, an abdominal ultrasound was obtained a year later demonstrating slight bilateral caliectasis without obvious visible cause for it. Laboratory exams have shown significantly impaired renal function, normocytic anaemia, slightly higher sedimentation rate, increased CRP and normal urinalysis. Nephrologist has decided for hospitalisation during which magnetic resonance imaging was performed  showing a few mm wide tissue coats surrounding both kidneys with fluid lying between the coat and kidney capsule. A biopsy of perirenal mass has confirmed a dense cellular lesion consisted of interweaved fascicles of spindle-shaped cells. After exclusion of tumours and other causes, a diagnosis of retroperitoneal fibrosis was confirmed. Clinical picture and laboratory data corresponded to idiopathic form of this disease. A treatment with tamoxifen was started after patient refused treatment with methylprednisolone. During tamoxifen monotherapy, there was gradual significant improvement of general symptoms, notable decline in inflammation markers, improvement of anaemia, normalisation of kidney function, and normalisation of blood pressure. Conclusion: Retroperitoneal fibrosis is still an obscure and multifaceted disease. A proper selection of diagnostic methods is the key to correct and fast diagnosis as well as good grounding for proper treatment.

    2009-01-01

    Aim: To report the magnetic resonance imaging (MRI) features of intracranial cystic meningiomas and compare these features in intra- and peritumoural cyst groups. Materials and methods: Fourteen cases of peritumoural cystic meningiomas were compared with 18 cases of intratumoural cystic meningiomas. All patients were examined using non-enhanced and contrast-enhanced MRI. Tumour location, tumour size, signal intensity, enhancement characteristics, and cystic changes were assessed. The MRI features were compared between the intra- and peritumoural cyst groups. Results: Most cystic meningiomas comprised two or more cysts. The solid parts of the tumours showed moderate or marked enhancement after the injection of contrast material. An enhanced cyst wall was found in six out of 14 cases in the peritumoural cyst group, but not in the intratumoural cyst group. Peritumoural cystic meningiomas were predominately located in the cerebral falx, whereas the intratumoural cystic meningiomas were predominantly found in frontal convexity (X 2 = 7.434, p = 0.024). The cysts were larger in the peritumoural cyst group than in the intratumoural cyst group (t = 5.274, p = 0.0258). Peritumoural oedema was more commonly found in the intratumoural cyst group (X 2 = 6.863, p = 0.008). Cystic meningiomas with solid parts located inside the cyst are reported for the first time. Conclusion: Cystic meningiomas, although uncommon, should be differentiated from other cystic intracranial lesions. Peri- and intratumoural cystic meningiomas have distinct MRI features. The present study provides the first report of two lesions with solid parts located inside the cyst, as well as one lesion with a calcified solid nodule and haemorrhage within the cyst.

    Full Text Available Cellular angiofibroma is a mesenchymal tumor, described in 1997, without gender preference, that usually appears at age 40. The vulvovaginal area is the most common site in women, mimicking vulvar benign tumors, like Bartholin gland cyst. However, there are a few described cases of a deep or extra-pelvic angiofibroma. Excision is the treatment of choice and the recurrence rate appears to be low. We present the case of a woman with a heterogeneous tumor in the right adnexial region. At the surgery, a retroperitoneal tumor was excised and the histopathological tissue analysis revealed a cellular angiofibroma.

    2013-01-01

    The aim is to present the variety of signs and symptoms from the diagnostic imaging methods of atypical neoplasms of the pancreas, presented as a type of cystic lesions. This often leads to unnecessary surgery or inappropriate tracking. In 115 patients (85 men and 30 women) with cystic lesions of the pancreas ultrasonic (US),computer tomography (CT) and magnetic resonance imaging (MRI) were performed and verified through histological and macroscopic pathology preparations. The ultrasound machines equipped with linear and convex transducers, MDCT and MRI imaging systems were used. In 14 of 115 patients atypical neoplasms of the pancreas were diagnosed: two cases with macroscopic serous cystic neoplasms, two nonmucinous cystic neoplasms, two hemorrhagic mucinous neoplasms, two ductal adenocarcinomas with cystic changes, one islet cell cystic tumor, two lymphoepithetial cysts, one lymphangioma, one solid papillary epithelial neoplasm and one mucinous adenocarcinoma. The authors take into consideration and overlapping of clinical symptoms and laboratory tests. Although much of the imaging features and morphological characteristics of cystic neoplasms of the pancreas are well known, should be known about the atypical unusual images in so-called 'typical' cystic neoplasms, cystic images in solid neoplasms and various atypical tumors with cystic lesions.

    2018-01-01

    The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases - underwent open pyelolithotomy. The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon.

    To the best of our knowledge, the formation of a retroperitoneal abscess due to acute appendicitis shortly after administration of chemotherapy for lung cancer has not been previously reported. This is the case report of a 59-year-old male who was admitted to the Mito Medical Center (Mito, Japan) and diagnosed with lung adenocarcinoma with pleuritis carcinomatosis. Although no distant metastasis was identified, combination chemotherapy with cisplatin and pemetrexed was administered. Nine days after initiating chemotherapy, the patient developed right lower quadrant abdominal pain and high fever. Computed tomography (CT) of the abdomen and pelvis revealed the collection of gas and fluid in the retroperitoneum adjacent to the cecum. The abscess was locally drained; however, the infection continued to spread, with subsequent development of a scrotal abscess. Consequently, appendectomy was performed. The patient recovered well and the lung adenocarcinoma was treated with additional courses of chemotherapy following the remission of the local inflammation. Retroperitoneal abscess due to acute appendicitis is an unusual finding; however, this rare complication should be considered during or shortly after chemotherapy in patients with lung cancer.

    Full Text Available Schwannomas are usually benign rare tumors that originating from Schwann cells of peripheral nerve sheaths. Presentation is generally varied and changed in a non-specific range from abdominal mass, flank pain to incidental findings. Herein we report 2 cases of retroperitoneal giant schwannomas with different clinical presentations, of whom one presented with vague abdominal pain, palpable abdominal mass for 4 years, swelling and bilateral hydronephrosis that caused by giant abdominal mass; the other one presented with right flank pain, rectal hemorrhage and lower extremities edema. Two patients were treated by complete surgical excision of masses. The histological and immunohistochemical diagnosis was reported as benign schwannoma. Both of patients are doing well and had no recurrence in 9 years and 28 months follow-up, respectively.

  1. Cystic tumors of the pancreas

    Cystic lesions of the pancreas encompass a broad spectrum of benign, premalignant, and malignant tumors which are primarily cystic or result from cystic necroses of solid neoplasms. Because of the wide use of cross-sectional imaging techniques they are increasingly being identified in asymptomatic patients as well as in patients presenting with abdominal pain, jaundice or pancreatitis. Among these lesions, intraductal papillary mucinous neoplasms, serous cystic neoplasms and mucinous cystic neoplasms represent the majority of cases. With increasing experience with these tumors, a refinement of our understanding of their morphology and of their natural course has emerged. It is important to be familiar with the CT and MR imaging features of these lesions to differentiate these tumors and to orient the diagnosis towards benign or malignant forms. Because characterization of cystic tumors of the pancreas can sometimes be difficult due to overlapping imaging features, additional criteria such as clinical symptoms, localization, age and gender have to be taken into account. If appropriately treated, these tumors can usually be cured by resection and the decreasing risk of pancreatic surgery has led to an increasing number of resections of pancreatic tumors. The management of cystic tumors of the pancreas has not yet been standardized and the correct evaluation and subsequent management of the disease in asymptomatic patients have not been fully defined.

    Many cephalosporin antibiotics have recently been invented and attempts have been made to use them clinically. The choice of which of these drugs should be used has been difficult in gynecology. The efficacies of these drugs depend on their antibacterial spectra, potencies, and concentrations in tissues. This study was designed to investigate the pharmacokinetics of various cephem antibiotics in the exudate of the retroperitoneal space that is formed after radical hysterectomy and pelvic lymphadenectomy. These cephem antibiotics were cefoxitin, cefotiam, cefotetan, cefpiramide, cefminox, cefotaxime, ceftizoxime, cefoperazone, cefmenoxime, cefbuperazone, ceftazidime, cefpimizole, flomoxef, and cefuzonam. The maximum concentrations after administration of a 1-g dose in the exudate of the pelvic retroperitoneal space were 37.9 micrograms/ml with cefminox, 30.3 micrograms/ml with cefpimizole, 21.6 micrograms/ml with flomoxef, 21.5 micrograms/ml with ceftazidime, and 17.6 micrograms/ml with cefbuperazone, which were relatively high. When selecting antibiotics for prophylactic use against infections in the retroperitoneal space after radical hysterectomy and pelvic lymphadenectomy, on the basis of drug transfer, flomoxef, cefminox, cefbuperazone, ceftazidime, and cefpimizole were considered to be the drugs of first choice at a dose of 1 g.

Methods: From 2 646 female patients underwent breast sonography at King Chulalongkorn Memorial Hospital from January 2005 through December 2010, 103 cystic lesions were included. Pathologic confirmation was performed by fine-needle aspiration (n=42, core needle biopsy (n=6, excision (n=54 and mastectomy (n=1. Complex cystic breast masses were classified into 3 types as followings; thick outer wall and/or thick internal septa (type I; thick septation and thick wall were defined as equal or more than 0.5 cm, masses containing mixed cystic and solid components (at least 50% of cystic component (type II, predominantly solid with eccentric cystic foci (at least 50% of solid component (type III. Results: In 103 complex cystic masses, there are 27 lesions (26% classified as type I cystic breast masses, 37 lesions (36% as type II cystic breast masses and 39 lesions (38% type III cystic breast masses, 26 lesions (25.2% are proved to be malignant. All of type I cystic breast masses in our study are benign, and 14 (38% of type II cystic breast masses and 12 lesions (31% of type III cystic breast lesions are proved to be malignant. Conclusions: Type II and III lesions should suggest possibility of malignancy and biopsy should be performed in all lesions. All type I lesion in this study are benign. None of other parameters we included in this study (size or margin can effectively differentiate between benign or malignant cystic breast lesions. Also, grading of the malignant lesions by using type of cystic breast mass cannot be applied.

    To describe CT findings and differential points of cystic thymic lesions. We evaluated retrospectively total 19 masses with well marginated cystic lesions at thymic area on CT scans. They were 10 teratomas, 3 congenital thymic cysts, 2 multilocular thymic cysts(associated with thymoma and myasthenia gravis in each), 2 cysts Assciated with thymic Hodgkin's lymphomas an ectopic parathyroid cyst, and an infected thymic cyst. The radiological abnormalities evaluated were thickness of the wall, presence or abscene of septa, mural nodule, solid component, calcification and fat component. All three cases of congenital thymic cysts and an ectopic parathyroid cyst appeared as thin-walled unilocular cyst with homogeneous internal density and without identifiable solid component. In multilocular thymic cyst, there were thick wall and solid components(n =2), thick internal septa and calcifications(n = 1). The cysts of teratomas manifested thick walls(n = 9), internal septa(n = 4), calcifications(n = 6), fat components(n = 4), and solid components(n = 4). Cysts in Hodgkin's diseases appeared as multilocular or unilocular and had thick wall and septa without calcification. Infected thymic cyst presented with multilocular cystic mass with identifiable wall and septa, calcification, and solid components. The thymic diseases with cystic lesion include teratomas, congenital thymic cysts, multilocular thymic cysts, parathyroid cyst, and Hodgkin's disease. Congenital thymic cyst and ectopic parathyroid cyst are thin-walled unilocular cystic lesions. Cystic lesions associated with teratoma, Hodgkin's disease, and multilocular thymic cyst are thick-walled cystic lesions with or without solid component

    To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilobular emphysema (n = 9), paraseptal emphysema and bullae (n = 16), cystic bronchiectasis (n = 13), and honeycombing (n = 9). Using paired inspiratory and expiratory HRCT scans obtained at the corresponding anatomic level, a total of 270 cystic lesions were selected simultaneously on the basis of five lesions per lung disease. Changes in lung cyst size observed during respiration were assessed by two radiologists. In a limited number of cases (n = 11), pathologic specimens were obtained by open lung biopsy or lobectomy. All cystic lesions in patients with Langerhans cell histiocytosis, lymphangiomyomatosis, cystic bronchiectasis, honeycombing, and confluent centrilobular emphysema became smaller on expiration, but in two cases of paraseptal emphysema and bullae there was no change. In cases in which expiratory CT scans indicate that cysts have become smaller, cystic lesions may communicate with the airways. To determine whether, for cysts and cystic lesions, this connection does in fact exist, paired inspiratory and expiratory HRCT scans are necessary

    1985-01-01

    A new cutting biopsy needle has been used to obtain histologically useful material while causing the minimum of trauma. It permits biopsies of organs, but its small external diameter of 0.8 or 0.95 mm makes it possible to carry out transperitoneal puncture of the stomach, colon or liver and of the retroperitoneal space, using a ventral approach. Tissue samples were obtained in 96% of 63 patients. The risk of complications is no higher than for conventional needles used for cytology. The accuracy with which the material can be obtained is therefore the most important problem. The position of the area to be biopsied should determine whether the biopsy is to be aided by sonography or CT. Biopsies of organs can be appropriately carried out under ultrasound control, but processes in the pelvis and in retroperitoneal-paravertebral and extra-peritoneal positions are best biopsied under CT control.

    A huge maternal hydronephrosis is uncommon in pregnancy and might be mistaken as a pelvic mass. A 21-year-old primigravida was noted at 25th week of gestation to have a visible bulging mass on her left flank. The mass was originally mistaken as a large ovarian cyst but later proved to be a huge hydronephrosis. Retrograde insertion of ureteroscope and a ureteric stent failed, so we performed repeated ultrasound-guided needle aspiration to decompress the huge hydronephrosis, which enabled the patient to proceed to a successful term vaginal delivery. Nephrectomy was performed after delivery and proved the diagnosis of congenital ureteropelvic junction obstruction.

    Objective To determine the prognostic significance of histologic type/subtype in a large series of patients with primary resected retroperitoneal sarcoma. Summary Background Data The histologic diversity and rarity of retroperitoneal sarcoma has hampered the ability to predict patient outcome. Methods From a single-institution, prospective database, 675 patients treated surgically for primary, non-metastatic retroperitoneal sarcoma during 1982–2010 were identified and histologic type/subtype was reviewed. Clinicopathologic variables were analyzed for association with disease-specific death (DSD), local recurrence (LR), and distant recurrence (DR). Results Median follow-up for survivors was 7.5 years. The predominant histologies were well-differentiated liposarcoma, dedifferentiated liposarcoma, and leiomyosarcoma. Five-year cumulative incidence of DSD was 31%, and factors independently associated with DSD were R2 resection, resection of ≥3 contiguous organs, and histologic type. Five-year cumulative incidence for LR was 39% and for DR was 24%. R1 resection, age, tumor size, and histologic type were independently associated with LR; size, resection of ≥3 organs, and histologic type were independently associated with DR. Liposarcoma and leiomyosarcoma were associated with late recurrence and DSD (as long as 15 years from diagnosis). For solitary fibrous tumor, local recurrence was uncommon (sarcoma. Histology predicts the pattern and incidence of LR and DR and will aid in more accurate patient counseling and selection of patients for adjuvant therapy trials. PMID:25915910

    2014-05-14

    People with cystic fibrosis and pancreatic insufficiency are at risk of fat soluble vitamin deficiency as these vitamins (A, D, E and K) are co-absorbed with fat. Thus, some cystic fibrosis centres routinely administer these vitamins as supplements but the centres vary in their approach of addressing the possible development of deficiencies in these vitamins. Vitamin A deficiency causes predominantly eye and skin problems while supplementation of vitamin A to excessive levels may cause harm to the respiratory and skeletal systems in children. Thus a systematic review on vitamin A supplementation in people with cystic fibrosis would help guide clinical practice. To determine if vitamin A supplementation in children and adults with cystic fibrosis:1. reduces the frequency of vitamin A deficiency disorders;2. improves general and respiratory health;3. increases the frequency of vitamin A toxicity. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 07 April 2014. All randomised or quasi-randomised controlled trials comparing all preparations of oral vitamin A used as a supplement compared to either no supplementation (or placebo) at any dose and for any duration, in children or adults with cystic fibrosis (defined by sweat tests or genetic testing) with and without pancreatic insufficiency. No relevant studies for inclusion were identified in the search. No studies were included in this review. As there were no randomised or quasi-randomised controlled trials identified, we cannot draw any conclusions on the benefits (or otherwise) of regular administration of vitamin A in people with cystic fibrosis. Until further data are available, country or region specific guidelines on the use of

    Cystic fibrosis is a common autosomal recessive disorder with drastic respiratory symptoms, including shortness of breath and chronic cough. While most of cystic fibrosis treatment is dedicated to mitigating the effects of respiratory dysfunction, the potential effects of this disease on vocal parameters have not been systematically studied. We hypothesized that cystic fibrosis patients, given their characteristic respiratory disorders, would also present dysphonic symptoms. Given that voice disorders can severely impair quality of life, the identification of a potential cystic fibrosis-related dysphonia could be of great value for the clinical evaluation and treatment of this disease. We tested our hypothesis by measuring vocal parameters, using both objective physical measures and the GRBAS subjective evaluation method, in male and female cystic fibrosis patients undergoing conventional treatment and compared them to age and sex matched controls. We found that cystic fibrosis patients had a significantly lower vocal intensity and harmonic to noise ratio, as well as increased levels of jitter and shimmer. In addition, cystic fibrosis patients also showed higher scores of roughness, breathiness and asthenia, as well as a significantly altered general grade of dysphonia. When we segregated the results according to sex, we observed that, as a group, only female cystic fibrosis patients had significantly lower values of harmonic to noise ratio and an abnormal general grade of dysphonia in relation to matched controls, suggesting that cystic fibrosis exerts a more pronounced effect on vocal parameters of women in relation to men. Overall, the dysphonic characteristics of CF patients can be explained by dysfunctions in vocal fold movement and partial upper airway obstruction, potentially caused by the accumulation of mucus and chronic cough characteristic of CF symptomatology. Our results show that CF patients exhibit significant dysphonia and suggest they may

    1987-01-01

    Renal cystic disease includes a group of lesions with extremely diverse clinical, radiographic, and pathologic findings. The recent development of multiple imaging systems to study renal cystic disease has resulted in considerable interest in correlating the images obtained by different modalities with each other and with the underlying gross pathology. A thorough knowledge of the disturbed morphology and natural history of these diseases will lead to a better understanding of their appearance on radiologic imaging. This refresher course correlates disturbed morphology with appearances on diagnostic imaging, urography, US, angiography, CT, and MR imaging. The advantages and limitations of each imaging method are detailed. A practical classification emphasizing differential features is presented. The presentation is divided into two parts. In the first part typical and atypical cystic masses, including acquired cystic disease (from dialysis), Von Hippel-Lindau disease, and the cystic disease of tuberous sclerosis are discussed. In the second part, polycystic kidney disease (dominant and recessive), medullary cystic disease, medullary sponge kidney, multicycle-dysplastic kidney, renal sinus cysts (peripelvic), and pluricystic kidney disease are discussed

    Purpose: To evaluate the CT findings of skeletal cystic echinococcosis. Material and Methods: CT findings of 7 patients with pathologically confirmed skeletal cystic echinococcosis were evaluated. Results: There were 4 men and 3 women, aged 36-75 years. Hydatid cysts were located in the spine (n=2), a rib (n=3), the pelvis and a vertebra (n=1), the pelvis and the left femur (n=1). The size of the lesions varied from 1 cm to 15 cm. CT showed well defined, single or multiple cystic lesions with no contrast enhancement, no calcification, no daughter cysts, and no germinal membrane detachment. The cystic lesion had a honeycomb appearance in 2 cases, there was pathologic fracture in 2 cases, bone expansion in 5 cases, cortical thinning in 6 cases, cortical destruction in 6 cases, bone sclerosis in 1 case, and soft tissue extension in 6 cases. Conclusion: Preoperative differential diagnosis of skeletal cystic lesions should include cystic echinococcosis, especially in endemic areas, since this diagnosis may easily be missed unless kept in mind.

    Full Text Available We report an extremely rare and unusual case of retroperitoneal and pelvic metastasis from primary squamous cell carcinoma of vallecula. Generally carcinoma oropharynx metastasizes to lungs, liver and bone while retroperitoneal and pelvic metastasis is rarely heard of. To the best of our knowledge this case is one of the scantly reported cases ever of this kind in the world.  A 60-year-old male presented with dysphagia and hoarseness of voice of four month duration.  Computed tomography (CT scan face and neck showed growth right vallecula. Biopsy of lesion showed squamous cell carcinoma. Metastatic work up was negative. He received definitive chemo-radiation. Patient during follow up presented with dyspepsia, abdominal discomfort and weight loss. Whole body positron emission tomography (WB PET scan revealed retroperitoneal and pelvic lymph node deposits which were confirmed as metastasis of squamous cell carcinoma by CT guided fine needle aspiration cytology (FNAC. Patient was exhibited palliative chemotherapy but his general condition deteriorated and he finally succumbed to his metastatic illness. This case is being reported to highlight its extreme rarity, the diagnostic and therapeutic challenges it presented and its overall dismal prognosis.

    Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.

    Objective: To evaluate the early response rate and radiation toxicity of CyberKnife in the treatment of primary or metastatic retroperitoneal tumors. Methods: Twenty-eight patients with retroperitoneal tumors were treated with CyberKnife. The total doses were 2000-6000 cGy (median 4500 cGy) and biological effective doses were 3750-10080 cGy (median 7680 cGy) in 2-10 fractions (median 5). Of all patients, 3 received three dimensional conformal radiotherapy (3DCRT) or intensity modulated radiotherapy (IMRT) boost, 1 was treated as second-course radiotherapy, and others were treated with CyberKnife only. The survival rates were calculated by Kaplan-Meier method and compared with Logrank test. Results: The complete response, stable disease and progression disease rates were 43% (12/28), 6% (10/28), 18% (5/28), 4%, (1/28), respectively. The overall response rate was 96%. The number of patients who were followed up more than 1, 2, 3 years were 17, 9, 7, respectively. The 1-, 2- and 3-year local control rates were 92%, 86%, and 86%, respectively. The 1-, 2- and 3-year overall survival rates were 60%, 49% and 49%, respectively. The difference between local progression-free survival and overall survival was not significant (median 9.5 and 12.0 months, χ 2 =0.17, P=0.680), Moreover, if the patients did not have metastasis elsewhere and local treatment was effective, there was no significant difference between local progression-free survival and progression free survival (median 17 and 11 months, χ 2 =0.13, P=0.720), Acute radiation-induced side effects (≥ 2 grade) such as fatigue, anorexia, nausea, vomiting and epigastric discomfort occurred in 9, 9, 7, 7 and 2 patients, respectively. Intestinal stenosis of 1 grade occurred in 1 patients. Conclusions: Radiotherapy for retroperitoneal tumors with CyberKnife has provided a high response rate with minimal side effects. It is a safe and effective local treatment method for retroperitoneal tumors. (authors)

    In hemodynamically unstable patients, the management of retroperitoneal vascular trauma is both difficult and challenging. Endovascular techniques have become an alternative to surgery in several trauma centers. Between 2004 and 2006, 16 patients (nine men, mean age: 46 years, range: 19-79 years) with retroperitoneal vascular trauma and hemodynamic instability were treated using an endovascular approach. The mean injury severity score was 30.7 ± 13.1. Mean systolic blood pressure and the shock index were 74 mm Hg and 1.9, respectively. Vasopressor drugs were required in 68.7% of cases (n = 11). Injuries were attributable to road traffic accidents (n = 15) and falls (n = 1). The hemorrhage sites included the internal iliac artery or its branches (n = 12) with bilateral injury in one case, renal artery (n = 2), abdominal aorta (n = 1), and lumbar artery (n = 1). In all, 14 coil embolizations and three stent-grafts were implanted. The technical success rate was 75%, as early re-embolization was necessary in one case and three patients died during the perioperative period. Six patients died during the period of hospitalization (37.5%). No surgical conversion or major morbidity was reported. In comparison with particulates, coil ± stent-graft may provide similar efficacy with regard to survival, and thus may be a valuable solution when particulate embolization is not available or feasible.

    Cystic echinococcosis (CE) is a widespread zoonosis caused by the species complex Echinococcus granulosus. Albendazole (ABZ)-the first-line anthelminthic drug for medical treatment of CE-is metabolized in vivo to the active derivative ABZ-sulphoxide (ABZ-SO). Target-site ABZ-SO concentrations in the hydatid cyst mediate the anthelminthic effect in CE. Primary outcome of this systematic review of individual patient data was the intra-cystic ABZ-SO concentration stratified by cyst size, location, calcification status and use of praziquantel. Studies reporting intra-cystic ABZ-SO concentrations in humans were identified by a systematic search. A pooled analysis of individual patient data was performed to assess intra-cystic concentrations. Pharmacokinetic data of 121 individual cysts were analysed. There was no correlation between plasma and intra-cystic ABZ-SO concentrations (rho = -0.03, p = 0.76). Intra-cystic drug concentrations were also not associated with sex and treatment duration. Use of praziquantel in combination with ABZ was associated with higher plasma (median 540 vs. 240 μg/L; p = 0.04) but not intra-cystic ABZ-SO concentrations (median 220 vs. 199 μg/L; p = 0.36). Relative drug concentrations in hepatic cysts were higher than in other cysts (0.8 vs. 0.4; p = 0.05). Intra-cystic concentrations were higher in calcified than non-calcified cysts (median 897 vs. 245 μg/L; p = 0.03). There was a trend towards higher intra-cystic concentrations in smaller sized cysts (β = -17.2 μg/L/cm; 95th CI, -35.9 to 1.6; p = 0.07). This study demonstrates that mean intra-cystic drug concentrations are similar to plasma concentrations on a population level. However, in individual patients plasma concentrations are not directly predictive for intra-cystic concentrations. The use of booster drugs was not associated with higher intra-cystic ABZ-SO concentrations in this analysis.

    Even though laparoscopic cholecystectomy (LC) emerged over 20 years ago, controversies persist with regard to the best method to ligate the cystic duct and artery. We proposed to assess the effectiveness and safety of electrocoagulation to seal the cystic artery and cystic duct after their occlusion with only one absorbable clip. We retrospectively compared the clinical data for 635 patients undergoing LC using electrocoagulation to seal the cystic artery and cystic duct that were occluded with only one absorbable clip (Group 1) and 728 patients undergoing LC using titanium clips (Group 2). In parallel, 30 rabbits randomized into six groups underwent cholecystectomy. After cystic duct ligation with absorbable or titanium clips, the animals were sacrificed 1, 3, or 6 months later, and intraabdominal adhesions were assessed after celiotomy. The mean operative time was significantly shorter (41.6 versus 58.9 minutes, PElectrocoagulation of the cystic artery and cystic duct that were occluded with only one absorbable clip is safe and effective during LC. This approach is associated with shortened operative times and reduced leakage, compared with the standard method using metal clips.

  11. Gastrointestinal Manifestations of Cystic Fibrosis

    Science.gov (United States)

    2016-01-01

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Retroperitoneal uterine leiomyoma is a very rare occurrence and to discover it as a cause of female sexual dysfunction in a teen is unusual. An 18-year-old black woman reported deep dyspareunia, resulting in severe distress. Gynecological and instrumental examinations showed a pelvic mass of 7 cm in diameter. The preoperative diagnosis was uterine fibroid, but the exact location of the leiomyoma was uncertain. Laparoscopic examination showed a pedunculated retroperitoneal cervical leiomyoma in the left pararectal space. After surgical excision of the mass, normal sexual activity was restored. When a teen experiences pain with intercourse, pelvic masses should be part of differential diagnosis of dyspareunia. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    2014-01-01

    We reported a case of spontaneous retroperitoneal hematoma (SRH) simulating a ruptured infrarenal aortic aneurysm. A 72-year-old man with a history of infrarenal aortic aneurysm and end-stage renal disease on hemodialysis presented with malaise and nonspecific central abdominal pain and left loin discomfort. An emergency computed tomography scan showed a large retroperitoneal hematoma and clinical suspicion of ruptured infrarenal aortic aneurysm. However, the hematoma was discontinuous with the aneurysm sac and raised the clinical suspicion on dual pathology. The SRH was treated conservatively with transfusion of blood products, and the aneurysm was treated with nonemergency endovascular repair electively. This case demonstrates the importance of recognizing different clinical and radiological characteristics and be aware of dual pathology. PMID:28031651

    Cystic follicles are a significant cause of infertility in women, dairy cattle and sheep. Sheep were used as a model to identify factors that may elicit formation of cystic follicles. Insulin resistance and elevated LH activity were tested in overweight ewes because of associations among these factors and the formation of cystic follicles. Sheep were synchronized using a progesterone-releasing pessary and insulin resistance was induced during the synchronization period through administration of bovine somatotropin. Following removal of pessaries follicular growth was stimulated by treatment with eCG or eCG and hCG (PG-600). Follicular growth was monitored via daily transrectal ultrasonography and blood samples were collected for hormonal analyses. Six of 18 ewes had a subnormal or absent preovulatory gonadotropin surge and developed cystic follicles. Neither insulin resistance nor elevated LH activity were associated with formation of cystic follicles. Ewes that developed cystic follicles were heavier (93 +/- 4 kg) than ewes that ovulated (81 +/- 3 kg; P = 0.02). Furthermore, following pessary removal and initiation of daily ultrasonography, ewes that developed cystic follicles lost body weight (-3 +/- 1%), while ovulatory ewes continued to gain body weight (1 +/- 1%; P = 0.005). It is speculated that in heavy ewes metabolic factors associated with acute body weight loss inhibit the positive feedback of estradiol and thereby suppress the preovulatory gonadotropin surge leading to formation of cystic follicles.

    Follicular dendritic cell sarcoma is a very rare neoplasm, which is not lymphoma, but originates from a type of immune cells called follicular dendritic cells. We presented a 37-year-old woman who has suffered from obstructive jaundice, weight loss and right upper abdominal pain for 2 months. The contrast CT revealed masses located in the region of pancreatic head and lots of enlarged retroperitoneal lymph nodes, both of which were enhanced on the artery phase of CT images. Meanwhile, Tc-HYNIC-TOC SPECT/CT revealed high activity in the corresponding lesions. After biopsy, the masses were pathologically confirmed as retroperitoneal follicular dendritic cell sarcoma.

    2001-01-01

    Objective: To study the imaging features of meningiomas of ethmoid sinuses. Methods: Six cases of meningiomas of ethmoid sinuses verified pathologically were analyzed retrospectively. Results: CT scans of 6 cases exhibited huge cystic masses (n = 3), huge cystic-solid masses (n = 2), huge solid mass (n = 1). The cystic walls were remarkable osteosclerosis. The density of solid masses were homogeneous, or heterogeneous with calcifications and cystic changes, and prominent contrast-enhancement. MR images of 1 case (1/6) showed a cystic-solid mass, the cystic portion was high signal intensity on T 2 WI and low signal intensity on T 1 WI, while the solid mass was iso-signal intensity on T 1 WI and T 2 WI. The solid portion was enhanced. X-ray plain films of 3 cases (3/6) displayed ethmoid sinuses enlargement and high density. Conclusion: For the meningiomas of ethmoid sinuses, CT finding was specific, MRI was helpful in differential diagnosis, and X-ray plain films was of no qualitative value

    A retroperitoneal myxoid liposarcoma of the renal capsule must be differentiated from renal cell carcinomas, angiomyolipomas, fibrogenous lipomas, fibrolipomas and mixed tumours containing fat tissue. Myxoid liposarcomas can lead to intracavale tumourthromboses, which is often the case with renal cell carcinomas and revealed clinical with Budd-Chiari syndrome. Computed tomography and magnetic resonance imaging give additional information in the diagnosis of intracaval tumourthromboses and show the exact expansion of the topographic-anatomical structure.

    2013-08-01

    To report a rare case of acute intraoperative retroperitoneal hemorrhage secondary to aortic penetration by the suprarenal anchoring barb on a stent-graft. A 75-year-old patient on dual antiplatelet therapy for coronary stents and low-molecular-weight heparin for atrial thrombus underwent elective endovascular repair of a 6.7-cm infrarenal abdominal aortic aneurysm. A device with suprarenal fixation and metal anchoring barbs was implanted, and a molding balloon was used that at no time covered the proximal bare metal stents or barbs. In recovery, the patient became tachycardic and hypotensive. After resuscitation, imaging identified an anterior barb penetrating the aortic wall, causing the acute retroperitoneal hemorrhage. A decision to treat conservatively rather than resort to open surgery was difficult but ultimately influenced by the patients' high risk for open surgery. The patient was treated by aggressive reversal of heparin and platelet transfusion, and the bleed settled spontaneously. Major surgery and subsequent morbidity may be avoided by medical management of what would appear to be a surgical problem.

  1. Cystic fibroepithelioma of Pinkus: two new cases and cystic changes in classical fibroepithelioma of Pinkus

    Zlatko Marusic

    2014-09-01

    Full Text Available We report two new cases of cystic fibroepithelioma of Pinkus together with immunohistochemical features and analyze the presence of cystic changes in a series of 16 classical fibroepitheliomas of Pinkus. Our findings show that the formation of cystic spaces is most probably caused by ischemic degeneration of stromal fenestrations, rather than by central tumor cell necrosis. This finding is supported by lack of CD34 positive blood vessels in edematous and hyalinized stromal fenestrations undergoing transformation into cystic spaces, as opposed to the uninvolved stromal fenestrations. Therefore, it is probably more accurate to refer to this process as pseudocystic stromal degeneration rather than true cyst formation. Also, two out of 16 classical Pinkus fibroepitheliomas exhibited focal pseudocystic changes in 50% and 10% of the tumor, respectively, demonstrating that this degenerative process can be found, rarely and focally, in classical cases as well.

    Full Text Available Introduction: Cystic Fibrosis is the most common recessive autosomic genetic disease among Caucasians. It's caused by mutations in the gene that decodes regulatory protein for transmembrane conductance, resulting in defective transport of chlorine. Objective: Review the literature about Cystic Fibrosis, with emphasis on otorhinolaryngologic manifestations. Method: The online Pub Med databases were researched and we applied the following search terms Fibrosis Cystic and Sinusitis, and Mucoviscidosis and Sinusitis. Conclusions: Although it is not the main cause of death, the otorhinolaryngologic manifestations of the Cystic Fibrosis bring important morbidity to these patients.

    Full Text Available Thornwaldt's bursa, also known as nasopharyngeal bursa, is a recess in the midline of the nasopharynx that is produced by persistent notochord remnants. If its opening becomes obstructed, possibly due to infection or a complication from adenoidectomy, a Thornwaldt's cyst might develop. Here, we present a 53-year-old man who complained of nasal obstruction that had progressed for 1 year. Nasopharyngoscopy showed a huge nasopharyngeal mass. Thornwaldt's cyst was suspected. Magnetic resonance imaging showed a lesion measuring 3.6 × 3.4 cm, intermediate on T1-weighted and high signal intensity on T2-weighted imaging, neither bony destruction nor connection to the brain. The patient underwent endoscopic surgery for this huge mass. Afterwards, his symptoms improved significantly. We present the treatment and differential diagnosis of a nasopharyngeal cyst.

    Teratomas are rare germline tumors that originate from one or more embryonic germ cell layers. Teratoma of the kidney is extremely rare, and less than 30 cases of primary intrarenal teratomas have been published to date. We report the main radiologic features of an unusual case of mature cystic teratoma arising from the left kidney in a two-year-old boy. A left-sided abdominal mass was detected on physical examination and B-Mod Ultrasound (US) examination revealed a heterogeneous mass with central cystic component. Computed tomography (CT) demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa. Nephrectomy was performed and a large, fatty mass arising from the left kidney was excised. The final pathologic diagnosis was confirmed as cystic renal teratoma

It is caused by a parasitic platyhelminth of the genus Echinococcus. We present a patient with a fluctuating lumbar tumor in the retroperitoneal space, secondary to a hepatic cyst. The initial diagnosis was made by identification of rostellar hooks from protoscoleces in the fluid aspirated from the abscess. We herein describe the clinical manifestations, diagnosis and medical and surgical treatment of this unusual case and conclude that the development of an accurate diagnosis required a proper analysis of the patient's epidemiological history, clinical manifestations, imaging studies and laboratory tests. A multidisciplinary approach and differential diagnosis is paramount to be able to establish a cause of the disease to deliver appropriate treatment.

    Graphite is a quasi-two-dimensional semimetal. However, for usual graphite the magnetoresistance is not so high due to its small crystal size and no preferred orientation. Huge positive magnetoresistance up to 85300% at 4.2 K and 4950% at 300 K under 8.15 T magnetic field was found in highly oriented pyrolytic graphite. The mechanism of huge positive magnetoresistance is not only due to ordinary magnetoresistance but also due to magnetic-field-driven semimetal-insulator transition

    Cystic liver lesions incorporate a broad heterogeneous group of mostly benign but also malignant abnormalities. The radiological aim is the non-invasive diagnosis with the use of different imaging modalities to determine the type of lesion. The common generally asymptomatic incidental findings of cystic lesions on ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) must be classified on the basis of specific imaging features. Such a differentiation is essential because the clinical consequences and the appropriate therapy can vary depending on the underlying pathology. Due to the morphological overlap of many cystic lesions, conventional radiological methods are often insufficient. The huge advances in cross-sectional imaging (multidetector CT, MRI with special sequences and different contrast agents and MR cholangiopancreatography) in combination with the clinical history usually enable a non-invasive diagnosis. Pathognomonic morphological and hemodynamic lesion features, as well as a knowledge of the pathomechanisms, help to differentiate this broad spectrum of entities. In this article the different entities of cystic liver lesions, together with the appropriate diagnostic method for detection and distinction and including their strengths and limitations, are demonstrated. A well-founded knowledge about the development of various cystic liver lesions and the suitable choice of imaging method facilitate a non-invasive diagnosis. (orig.)

    CT was undertaken and CT numbers were measured in 47 patients with cystic ovarian lesions. CT features particularly for chocolate cyst revealed the uniform thickness of the whole cystic wall, findings suggesting adhesion to the surrounding organs, circular or oval shape, and higher CT numbers within the cyst than those in the other cystic ovarian lesions. However, because these features are not always observed in cases of chocolate cyst, one should not rely solely on CT findings in the diagnosis of chocolate cyst. (Namekawa, K.)

    Full Text Available Dedifferentiated liposarcoma (DDL is a histologically pleomorphic sarcoma, traditionally defined as well-differentiated liposarcoma with abrupt transition to high grade, nonlipogenic sarcoma. It can occur as part of recurrent well-differentiated liposarcoma, or may arise de novo. DDL most frequently occurs within the retroperitoneum, and while it is prone to local recurrence, it usually has a lower rate of metastasis than other pleomorphic sarcomas. We describe a case of retroperitoneal dedifferentiated liposarcoma in a 63-year-old male, who showed MDM2 amplification with fluorescence in situ hybridization, which displayed unusually aggressive behavior, with brain, lung and subcutaneous soft tissue metastases. As previous reports of metastatic liposarcoma have largely grouped DDL in with other (genetically and clinically distinct liposarcoma subtypes, we highlight and discuss the rare occurrence of brain metastasis in MDM2-amplified retroperitoneal liposarcoma.

    Full Text Available ABSTRACT Objectives The aim of our study is to present early outcomes of our series of retroperitoneal-RAPN (Robot Assisted Partial Nephrectomy. Materials and methods From September 2010 until December 2015, we performed 81 RAPN procedures (44 at left kidney and 37 at right. Average size was 3cm (1-9. Average PADUA score 7.1 (5-10. Average surgical time (overall and only robot time, ischemia time, blood loss, pathological stage, complications and hospital stay have been recorded. Results All of the cases were completed successfully without any operative complication or surgical conversion. Average surgical time was 177 minutes (75-340. Operative time was 145 minutes (80-300, overall blood loss was 142cc (60-310cc. In 30 cases the pedicle was late clamped with an average ischemia time of 4 minutes (2-7. None of the patient had positive surgical margins at definitive histology (49pT1a, 12pT1b, 3pT2a, 2pT3a. Hospital stay was 3 days (2-7. Conclusions The retroperitoneal robotic partial nephrectomy approach is safe and allows treatment of even quite complex tumors. It also combines the already well known advantages guaranteed by the da Vinci® robotic surgical system, with the advantages of the retroperitoneoscopic approach.

    Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

    Background: Cystic duct leakage after cholecystectomy is not uncommon and is a potentially serious complication. The aim of this study was to assess a bipolar sealing system (LigaSure®) for closure of the cystic duct. Methods: The records from consecutive laparoscopic cholecystectomies performed in 2 hospitals with closure of the cystic duct with LigaSure after informed consent were recorded and complications and morbidity registered. The records were compared with those of patients undergoing laparoscopic cholecystectomy with closure of the cystic duct with clips during the same period. Results: During the study period, 218 laparoscopic cholecystectomies were performed; 102 of these were performed with the LigaSure. One patient was excluded due to violation of the protocol. We experienced no cases of cystic duct leakage, but in one patient, bile leakage from the gallbladder bed was observed probably due to a small aberrant duct. Conclusion: The LigaSure system was safe and effective for closure and division of the cystic duct in laparoscopic cholecystectomy. PMID:20412641

    Full Text Available We report a case of immunoglobulin G4 (IgG4-related retroperitoneal fibrosis (RF with complete remission and no relapses after therapy with steroids and Hochuekkito, a Kampo (i.e. traditional Japanese herbal medicine. A 62-year-old Japanese man was admitted to our hospital for treatment of a retroperitoneal mass detected by computed tomography. The mass had a maximum diameter of 11.0 cm; it involved the left ureter and was associated with left hydronephrosis. After inserting a ureteral stent, we performed a biopsy by laparotomy. Histopathology revealed IgG4-related RF. The lesion disappeared after 7 months of steroid therapy. We subsequently used Hochuekkito as an alternative maintenance treatment because of steroid-related complications. The patient has not relapsed in the 3 years since starting the medication. To the best of our knowledge, this is the first case of IgG4-related RF treated with Hochuekkito as a maintenance treatment.

    Pelvic fractures may lead to severe retroperitoneal bleeding. Percutaneous catheter embolisation has become an increasingly important therapeutic alternative to surgical intervention. Most studies dealing with this problem have been small and we have attempted to evaluate the method on the basis of our own experience and a review of the literature. The success rate of percutaneous embolisation appears to be about 94%. The use of blood transfusion dropped from an average of 25.7 units before embolisation to an average of 6.5 units after embolisation. In spite of this, mortality in these patients remains high at 43.3% because of the serious additional injuries. The advantages and disadvantages of various embolising materials are discussed and various techniques of percutaneous embolisation are described. (orig.) [de

    Full Text Available Autoimmune pancreatitis (AIP can be chronic or recurrent, but frequently completely reversible after steroid treatment. A cystic lesion in AIP is a rare finding, and it can mimic a pancreatic cystic neoplasm. Difficulties in an exact diagnosis interfere with treatment, and surgery cannot be avoided in some cases. We report the history of a 63-year-old male presenting with jaundice and pruritus. AIP was confirmed by imaging and elevated IgG4 blood levels, and the patient completely recovered after corticosteroid therapy. One year later, he presented with a recurrent episode of AIP with elevated IgG4 levels, accompanied by the appearance of multiple intrapancreatic cystic lesions. All but 1 of these cysts disappeared after steroid treatment, but the remaining cyst in the pancreatic head was even somewhat larger 1 year later. Pancreatoduodenectomy was finally performed. Histology showed the wall of the cystic lesion to be fibrotic; the surrounding pancreatic tissue presented fibrosis, atrophy and lymphoplasmacytic infiltration by IgG4-positive cells, without malignant elements. Our case illustrates the rare possibility that cystic lesions can be part of AIP. These pseudocysts appear in the pancreatic segments involved in the autoimmune disease and can be a consequence of the local inflammation or related to ductal strictures. Steroid treatment should be initiated, after which these cysts can completely disappear with recovery from AIP. Surgical intervention may be necessary in some exceptional cases.

    2009-07-06

    A new clinicopathological concept of IgG4-related sclerosing disease affecting various organs has recently been proposed in relation to autoimmune pancreatitis. This report describes the case of IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis, which recurred after a long period of spontaneous remission. An 80-year-old Japanese man presented with obstructive jaundice owing to a hepatic hilum bile duct stricture. Coincidentally, a soft tissue mass surrounding the abdominal aorta, suggesting retroperitoneal fibrosis, was identified. Unexpectedly, spontaneous regression of obstructive jaundice together with retroperitoneal fibrosis occurred. The presence of high serum IgG4 concentrations measured later led us to consider a possible association with autoimmune pancreatitis; however, there were no clinical features confirming autoimmune pancreatitis. After a 5-year history of spontaneous clinical remission, there was an elevation of serum IgG4 levels and renal dysfunction owing to bilateral hydronephrosis caused by a reemergence of the retroperitoneal mass. Evaluation by endoscopic retrograde cholangiopancreatography revealed a biliary stricture, suggesting sclerosing cholangitis which was observed without the presence of any pancreatic duct abnormality. The subsequent excellent results obtained using steroid therapy, namely the decrease in serum IgG4 levels and the regression of the retroperitoneal mass, strongly suggested that the present case was an IgG4-related sclerosing disease. Aside from high serum IgG4 concentrations, markedly elevated levels of serum IgE was found retrospectively, although the clinical significance remains unknown. When we encounter fibrotic diseases of unknown etiology, we should measure serum IgG4 concentrations and monitor the disease activity over long periods even after achieving clinical remission.

    This study aims to investigate the application of the modified R.E.N.A.L. nephrometry score system in evaluating the operation difficulty of retroperitoneal partial nephrectomy in T1 renal cell carcinoma patients. A total of 52 patients with T1 renal cell carcinoma were enrolled. They all had retroperitoneal partial nephrectomy. Their clinical data was retrospectively analyzed. R.E.N.A.L. nephrometry score system was modified based on the features of retroperitoneal partial nephrectomy. The specificity, sensitivity and Youden index were compared between R.E.N.A.L. nephrometry score system and the modified R.E.N.A.L. nephrometry score system. The effect of the modified R.E.N.A.L. nephrometry score system on perioperative outcomes was analyzed. Three degrees of operation difficulty were defined by the modified R.E.N.A.L. nephrometry score system, which included the low, medium and high degree of operation difficulty. The specificity, sensitivity and Youden index of the modified R.E.N.A.L. nephrometry score system were better than those of the original R.E.N.A.L. nephrometry score system. Compared with low degree of operation difficulty, patients with medium and high degree of operation difficulty had significantly higher levels of operative time, warm ischemia time, and intraoperative blood loss (P system has a good effect in evaluating the operation difficulty of retroperitoneal partial nephrectomy.

  8. Chronic expanding hematoma in the retroperitoneal space: a case report

    Science.gov (United States)

    2013-01-01

    Background Chronic expanding hematoma is a rare condition that develops after surgery, trauma, or injury. It can also develop at any location in the body in the absence of trauma. Clinical findings and various diagnostic imaging modalities can aid in the differential diagnosis of this condition. In general, hematomas are naturally reabsorbed and rarely cause serious problems. However, hematomas that develop slowly without a history of trauma, surgery, or bleeding disorders could be difficult to differentiate from soft tissue neoplasms. In the present case, we describe a patient, without any history or physical evidence of trauma, who exhibited a large chronic expanding hematoma in the retroperitoneal space that resulted in hydronephrosis because of the pressure exerted on the left ureter. Case presentation A 69-year-old man presented to our hospital with a swollen lesion in the left flank. A mass, 19 cm in diameter, was detected in the retroperitoneal space by computed tomography. We suspected the presence of a chronic expanding hematoma, soft tissue tumor, or left renal artery aneurysm. Surgical treatment was performed. However, postoperative histopathological examination indicated that the mass was a nonmalignant chronic expanding hematoma. No recurrence was observed during a 2-year follow-up period. Conclusion In patients without a history of trauma who present slowly growing masses, the differential diagnosis should include chronic expanding hematoma in addition to cysts and soft tissue tumors. Moreover, the use of magnetic resonance imaging and computed tomography is essential to differentiate between chronic expanding hematoma and soft tissue tumors. PMID:24237992

    The excision of large retroperitoneal masses poses a challenge for every surgeon. Sometimes the urologist must face situations that do not fit to any conventional approach or technique previously described. Obtaining adequate exposure for safe and oncologically correct management of these masses is based, on many cases, in the mobilization of anatomical adjacent structures to generate a sufficient field in abdominal areas of difficult access. Complex visceral mobilization maneuvers derived from multivisceral transplantation organ procurement surgery provides ancillary techniques that used properly facilitate their successful resolution. The main purpose of this paper is the description of these surgical maneuvers essential to increase both exposure and vascular control in addressing the ever-dreaded high-volume retroperitoneal masses.

    Full Text Available Numerous accounts documenting the introduction of foreign bodies into the urinary bladder have been reported. These foreign bodies are typically self-inserted via urethral but migration from adjacent organs by an ulcerative process and penetrating injuries are also reported. However, "contrary" migration of a self-inflicted vesical foreign body to the retroperitoneum was not previously reported in literature. We report here a case of a ballpoint pen self-inserted via urethral by a female patient, which was identified in retroperitoneal position years later.

    To seek for the ultrasound (US) findings of partially cystic thyroid nodules that are associated with malignancy. We reviewed the US characteristics of 22 surgically confirmed partially cystic papillary carcinomas, and compared them with those of 80 benign partially cystic nodules. The review cases were selected in a random order from a total of 1029 partially cystic nodules that were diagnosed with an US-guided fine needle aspiration biopsy over a period of 8 years (June 2003 to October 2010) at our institution. In partially cystic thyroid nodules, a taller-than-wide shape (100%, p<0.001) and spiculated or microlobulated margin (58.3%, p 0.003) were significantly associated with malignancy. In terms of internal solid portion of the nodule, eccentric configuration (68.0%, p<0.001), non-smooth margin (81.3%, p<0.001), hypoechogenecity (30.0%, p<0.042), and microcalcification (89.5%, p<0.001) were more frequently demonstrated in malignant nodules than benign ones. In partially cystic thyroid nodules, understanding the characteristics of US findings is important to make a precise diagnosis of malignant nodules.

    Full Text Available Congenital encephalocele is a neural tube defect characterized by a sac-like protrusion of the brain, meninges, and other intracranial structures through the skull, which is caused by an embryonic development abnormality. The most common location is at the occipital bone, and its incidence varies according to different world regions. We report a case of an 1-month and 7-day-old male child with a huge interparietal-posterior fontanel meningohydroencephalocele, a rare occurrence. Physical examination and volumetric computed tomography were diagnostic. The encephalocele was surgically resected. Intradural and extradural approaches were performed; the bone defect was not primarily closed. Two days after surgery, the patient developed hydrocephaly requiring ventriculoperitoneal shunting. The surgical treatment of the meningohydroencephalocele of the interparietal-posterior fontanel may be accompanied by technical challenges and followed by complications due to the presence of large blood vessels under the overlying skin. In these cases, huge sacs herniate through large bone defects including meninges, brain, and blood vessels. The latter present communication with the superior sagittal sinus and ventricular system. A favorable surgical outcome generally follows an accurate strategy taking into account individual features of the lesion.

    2017-12-01

    Full Text Available Peritoneal dialysis (PD is an accepted modality for managing end-stage kidney disease. We herein report a 75-year-old female patient on chronic PD who was complicated by renal cell carcinoma. She was successfully treated with retroperitoneal laparoscopic radical nephrectomy followed by a prompt resumption of the procedure. Various surgeries disturbing the abdominal wall integrity often disrupt the regular PD schedule, and using minimally invasive approaches is therefore an attractive therapeutic option. Our experience emphasizes the feasibility and safety of a retroperitoneal approach–based laparoscopic technique based on several empirical examples. However, systemic studies on this topic are obviously lacking, so we strongly recommend the accumulation of more cases similar to our own. Several surgical concerns that need to be dealt with among PD patients are also discussed.

    An adenocarcinoma arising from mature teratoma is one form of teratoma with malignant transformation. It is extremely rare but highly malignant. The authors report two patients with adenocarcinomas arising from primary retroperitoneal teratomas. The CT and MRI findings of the tumors are presented with emphasis on imaging features implying the presence of malignant transformation and differing from those of pure benign mature teratoma. Correct diagnosis of the presence of malignant transformation from a benign mature teratoma can be made as early as possible by awareness of the imaging features. (orig.)

    2015-01-01

    Cystic fibrosis is the most common fatal inherited autosomal recessive disease in Caucasians, affecting approximately one out of every 2,000 births. Survival of patients with cystic fibrosis has significantly improved due to advances in respiratory and nutritional care, and their current average life expectancy is 30-40 years. Development of cystic fibrosis-related diabetes is a comorbidity that increases with age and may reach a prevalence up to 50% in adults. Its development is associated to impaired lung function and nutritional status, and early diagnosis and treatment are therefore essential to improve quality of life and performance status. Insulin therapy for diabetes and other early carbohydrate metabolism disorders may improve lung function and nutritional status of patients with cystic fibrosis. Copyright © 2014 SEEN.

    2015-01-01

    Purpose of Review Upper airway disease engenders significant morbidity for patients with cystic fibrosis and is increasingly recognized as having a much greater role in pulmonary outcomes and quality of life than originally believed. Widespread disparate therapeutic strategies for cystic fibrosis chronic rhinosinusitis underscore the absence of a standardized treatment paradigm. This review outlines the most recent evidence-based trends in the management of upper airway disease in cystic fibrosis. Recent Findings The unified airway theory proposes that the sinuses are a focus of initial bacterial colonization which seeds the lower airway and may play a large role in maintaining lung infections. Mounting evidence suggests more aggressive treatment of the sinuses may confer significant improvement in pulmonary disease and quality of life outcomes in cystic fibrosis patients. However, there is a lack of high-level evidence regarding medical and surgical management of cystic fibrosis chronic rhinosinusitis that makes generalizations difficult. Summary Well designed clinical trials with long-term follow-up concerning medical and surgical interventions for cystic fibrosis sinus disease are required to establish standardized treatment protocols, but increased interest in the sinuses as a bacterial reservoir for pulmonary infections has generated considerable attention.

    Evidence suggests that cystic fibrosis liver disease (CFLD) does not affect mortality or morbidity in patients with cystic fibrosis (CF). The importance of gender and age in outcome in CF makes selection of an appropriate comparison group central to the interpretation of any differences in mortality and morbidity in patients with CFLD.

  6. [Genetic counseling in cystic fibrosis].

    Genetic counseling is an important part of health care in patients with cystic fibrosis or respiratory diseases associated with the CFTR (cystic fibrosis transmembrane conductance regulator) gene, including certain types of allergic bronchopulmonary aspergilloses or bronchial diseases (diffuse bronchiectasia). The basic goal is to provide patients with information on the transmission of cystic fibrosis and to asses the risk of recurrence. This risk is determined from molecular biology analyses examining the CFTR gene. Genotyping is the only means of screening for the heterozygous state, frequent in the French population (about 1/30). Because of the large number of mutated alleles not covered entirely by the genetic tests, there remains a question of probability expressed as a residual risk of a heterozygous state. A prenatal genotype diagnosis should be proposed to heterozygous couples who have a 25% risk of having a diseased child. Technically, this is almost always possible and the results are highly reliable. Nevertheless, there remains the risks related to sample taking and the ethical issue about which the patients must be informed. Management of these at risk couples who desire a child must be based on a multidisciplinary approach, particularly important when one of the parents has overt cystic fibrosis.

    2018-01-01

    Retroperitoneal sarcomas (RPS) have fascinated and intrigued physicians both past and present. Operative mortality rates were historically very high and complete resection was not possible for the majority of patients until only the last 2 decades. More recently, changes to the surgical approach and clinical decision-making in RPS have improved patient outcomes. With select integration of nonsurgical therapies, continued RPS-specific research, and ongoing collaborative efforts among major referral centers, the future appears promising. © 2017 Wiley Periodicals, Inc.

    1987-01-01

    We retrospectively analysed CT findings of 47 cystic brain lesions of 44 patients, in which operation, biopsy or follow-up study was needed for their final diagnosis. The results were as follows: 1. The etiologic diseases of cystic brain lesions were 15 cases of brain abscess, 9 cases of astrocytoma, 5 cases of glioblastoma multiforme, 3 cases of meningioma, 5 cases of craniopharyngioma, 1 case of hemangioblastoma, 2 cases of dermoid cyst and 4 cases of metastasis. 2. We analyses the cystic lesions in view of their number, location, shape, perifocal edema, mass effect, wall and its thickness, evenness and characteristics of their inner and outer surfaces, mural nodule, calcification and contrast enhancement. a. 13.3% of brain abscess and 75% of metastases were multiple in number, but the remainder showed single lesion. b. The shape of cystic lesions were round or ovoid in 68%, lobulated in 8.5% and irregular in 23.5%, and no demonstrable difference of shape were noticed in different disease. c. In brain abscess, the wall of cystic lesions tend to be thin, even and smooth in inner surface, but the outer surfaces were equally smooth or irregular. d. Mural nodules were found in nearly half of the cases of astrocytoma, glioblastoma multiforme, metastasis and hemangioblastoma, but the brain abscess and dermoid cyst contained no mural nodule. e. Meningiomas were found to be attached to dura mater and showed thickening of the inner table of adjacent skull or of the falx. f. The presence of preceding infectious disease may be helpful in the diagnosis of brain abscess, but in 20% there were no demonstrable preceding infection. g. Lung cancer was confirmed as primary site in two of the cystic metastatic disease, but other 2 cases showed no demonstrable primary malignancy

    This article presents a narrative review of cystic lesions around the hip and primarily consists of 5 sections: Radiological examination, prevalence, pathogenesis, symptoms, and treatment. Cystic lesions around the hip are usually asymptomatic but may be observed incidentally on imaging examinations, such as computed tomography and magnetic resonance imaging. Some cysts may enlarge because of various pathological factors, such as trauma, osteoarthritis, rheumatoid arthritis, or total hip arthroplasty (THA), and may become symptomatic because of compression of surrounding structures, including the femoral, obturator, or sciatic nerves, external iliac or common femoral artery, femoral or external iliac vein, sigmoid colon, cecum, small bowel, ureters, and bladder. Treatment for symptomatic cystic lesions around the hip joint includes rest, nonsteroidal anti-inflammatory drug administration, needle aspiration, and surgical excision. Furthermore, when these cysts are associated with osteoarthritis, rheumatoid arthritis, and THA, primary or revision THA surgery will be necessary concurrent with cyst excision. Knowledge of the characteristic clinical appearance of cystic masses around the hip will be useful for determining specific diagnoses and treatments. PMID:26495246

  11. Laryngeal adenoid cystic carcinoma: case report

    Directory of Open Access Journals (Sweden)

    André Del Negro

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

    Full Text Available Abstract Background The objective of this study was to develop a modified retroperitoneal laparoscopic nephrectomy and compare its results with the previous technique. Methods One hundred retroperitoneal laparoscopic nephrectomies were performed from February 2007 to October 2011. The previous technique was performed in 60 cases (Group 1. The modified technique (n = 40 included fast access to the renal pedicle according to several anatomic landmarks and early ligation of renal vessels (Group 2. The mean operation time, mean blood loss, duration of hospital stay conversion rate and complication rate were compared between the groups. Results No significant differences were detected regarding mean patient age, mean body mass index, and tumor size between the two groups (P >0.05. The mean operation time was 59.5 ± 20.0 and 39.5 ± 17.5 minutes, respectively, in Groups 1 and 2 (P P P >0.05. Conclusions Early ligature using fast access to the renal vessels during retroperitoneal laparoscopic radical nephrectomy contributed to less operation time and intraoperative blood loss compared with the previous technique. In addition, the modified technique permits the procedure to be performed following the principles of open radical nephrectomy.

    A cystic lesion in the lung is defined as a well-demarcated epithel-lined cavity, that can be mostly filled with air, water, as well as solid material content. This definition includes a wide variety of diseases such as bronchogenic cyst, abscess formation, lymphangioleiomyomatosis, Langerhans cell histiocytosis, emphysema, bronchiectasis, and pneumatoceles. Despite the difficulties in differential diagnosis, there are some diagnostic criteria for CT-scanning helping the radiologist to differentiate between these cystic entities. Moreover, clinical informations are extremely important. The most important clinical parameters include age, sex, clinical history and symptoms. Thus, a better understanding of classic CT appearance of cystic lung disease will allow more definitive diagnosis and could, in some cases, avoid biopsy. (orig.)

    Failure to thrive (FTT) is a state of overall decline. Patients often present with weight loss, poor appetite, malnutrition, and decreased physical functioning. The etiology is multifactorial including chronic diseases, functional impairments, and acute illnesses. Evaluation for reversible causes is paramount, and treatment is aimed at maintaining or improving functional status. We present a case of a 91-year-old woman with a retroperitoneal mass that was found on workup for failure to thrive.

    Self-management education may help patients with cystic fibrosis and their families to choose, monitor and adjust treatment requirements for their illness, and also to manage the effects of illness on their lives. Although self-management education interventions have been developed for cystic fibrosis, no previous systematic review of the evidence of effectiveness of these interventions has been conducted.

    The aim of this study is to review the different histological and clinical characteristics of glioblastoma multiforme (GBM) with and without cysts (cystic and noncystic GBM, respectively). Thirty-seven GBM were collected; these were tumors for which more than 80% of the volume was surgically resected, including a portion of the peripheral parenchyma of the brain. Based on preoperative magnetic resonance (MR) imaging studies, tumors were tentatively classified as cystic GBM if more than 50% of their volume appeared to be liquid; otherwise, they were considered to be noncystic GBM. Tumor volumes were estimated from contrast-enhanced T 1 -weighted MR images. Edema was deduced from the maximum width of contrast-enhanced edges. Peritumoral pathological analysis showed distinct margins, indicating little or no infiltration of tumor cells into white matter. Five cases were classified as cystic and 32 were noncystic GBMs. There was a statistically significant difference in age (Mann-Whitney U test; P<0.05) between the patients with cystic tumors (median, 44 years; range, 26-59 years) and those with noncystic tumors (median, 54 years; range, 26-81 years). Four of the cystic tumors and eight of the noncystic tumors were more than 5 cm in maximum diameter. Cystic GBMs had a well-defined tumor interface and less than 2-cm-thick peritumoral edema compared to the noncystic GBMs (Fisher's exact test; P<0.05). For patients with cystic GBMs, median survival time after surgery was 19.8 months and the 2-year survival rate was 50%. Patients with noncystic GBMs had a median survival time of 12.8 months and a 2-year survival rate of only 17%. Median time to tumor recurrence was 13.3 months for patients harboring cystic GBMs and 8.5 months for those with noncystic GBMs (log-rank test; P<0.05). Thus, the prognosis for cystic GBM was significantly better than that for noncystic GBM, possibly because cystic GBMs showed comparatively little infiltration of the peritumoral brain parenchyma

    To perform arterial or venous spleno-renal anastomoses, surgeons have so far systematically used the transperitoneal way whic is burdened by a high mortality an morbility percentage. On the basis of anatomo-surgical considerations, a retroperitoneal approach has been found reaching the hilus of the spleen via the lumbar region; the first arterial spleno-renal anastomosis by this way was performed in 1972 and the first venous spleno-renal anastomosis due to portal hipertension also by this way was performed in 1974, the alter proving to be the least aggresive by avoiding damaging the páncreas, the most surgical and direct for reaching the splenic vessels thereby enabling a better exposure and an easier performing of the anastomoses. By being retroperitoneal, the loss or infección of the ascitic liquid in the cirrhotic patient is prevented.

    Full Text Available Mucinous cystic neoplasms (MCNs make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian organs such as pancreas, hepatobiliary tract and mesentery. MCNs of the pancreas occur almost exclusively in women. Here, we report a rare case of MCN in a male patient. A 39-year-old man was admitted to our hospital with the chief complaint of back pain. Abdominal computed tomography revealed a multilocular cyctic mass 6.3 cm in diameter in the pancreatic tail. In addition, the outer wall and septae with calcification were demonstrated in the cystic lesion. On magnetic resonance imaging , the cystic fluid had low intensity on T1-weighted imaging and high intensity on T2-weighted imaging. Endoscopic retrograde cholangio-pancreatography (ERCP showed neither communication between the cystic lesion and the main pancreatic duct nor encasement of the main pancreatic duct. Endoscopic ultrasonography revealed neither solid component nor thickness of the septae in the cystic lesion. Consequently, we performed distal pancreatectomy with splenectomy under the diagnosis of cystic neoplasia of the pancreas. Histopathologically, the cystic lesion showed two distinct component: an inner epithelial layer and an outer densely cellular ovarian-type stromal layer. Based on these findings, the cystic lesion was diagnosed as MCN.

    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

    Full Text Available Objective: To assess the incidence of cystic changes in the impacted lower third molar (ILTM in which the pericoronal (follicular space is less than 2.5 mm as measured from the radiograph. The relationship between the cystic changes and patient′s age, sex, and angular position and contact of ILTM with adjacent tooth was also evaluated. Materials and Methods: Follicular space less than 2.5 mm as measured from the panoramic radiograph was included in the study. A total of 73 tissue samples collected during the extraction ILTM were examined histopathologically. Then the data were analyzed for associations with age, sex, angular position, and contact of the ILTM with an adjacent tooth. Results: There were 37 male and 36 female patients, age ranging from 17 to 35 years (mean 23.95 years. Out of 73 specimens, 17 (23.3% showed cystic changes; among them 16 (22.1% showed dentigerous cysts and 1 (1.2% showed odontogenic keratocysts. Most of the cystic changes occurred in the 26-30 year age range. The cystic changes showed male predominance but could not gain statistical significance. The relationship between cystic changes and angular position was statistically significant (P < 0.05. Higher probability was found in distoangular positioned ILTM. The relationship between cystic changes and communication of ILTM with the second molar was not statistically significant. Conclusion: Incidence of cystic changes in ILTM justifies extraction of the impacted tooth associated with symptoms. The decision to extract or not to extract impacted third molar should be individualized, rather than generalized.

  5. Interdisciplinary Management of Cystic Neoplasms of the Pancreas

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Cystic neoplasms of the pancreas are increasingly recognized due to the frequent use of abdominal imaging. It is reported that up to 20% of abdominal cross-sectional scans identify incidental asymptomatic pancreatic cysts. Proper characterization of pancreatic cystic neoplasms is important not only to recognize premalignant lesions that will require surgical resection, but also to allow nonoperative management of many cystic lesions that will not require resection with its inherent morbidity. Though reliable biomarkers are lacking, a wide spectrum of diagnostic modalities are available to evaluate pancreatic cystic neoplasms, including radiologic, endoscopic, laboratory, and pathologic analysis. An interdisciplinary approach to management of these lesions which incorporates recent, specialty-specific advances in the medical literature is herein suggested.

    1987-09-01

    An endothelial cell line derived from a massive recurrent chyle-containing retroperitoneal lymphangioma was isolated in monolayer culture. Scanning and transmission electron microscopy and immunohistochemistry confirmed a close resemblance to blood vascular endothelium with typical cobblestone morphology, positive immunofluorescence staining for endothelial marker Factor VIII-associated antigen and fibronectin, and prominent Weibel-Palade bodies. The endothelial cells also exhibited other ultrastructural features characteristic of lymphatic endothelium, including sparse microvillous surface projections, overlapping intercellular junctions, and abundant intermediate filaments. This endothelial cell line represents a new source of proliferating lymphatic endothelium for future study, including structural and functional comparison to blood vascular endothelium.

    Full Text Available Abstract Soft tissue sarcomas are uncommon tumors, and intraduodenal soft tissue sarcoma manifestation is even more rare. Only three cases of intraduodenal sarcomas have been reported in the literature thus far. Here, we report a case of an intraduodenal recurrence of a retroperitoneal sarcoma causing bowel obstruction. This unusual recurrence pattern likely relates to the patient’s previous resection and radiation treatment, and highlights the benefits, limitations and follow-up strategies after multimodality treatment.

    We consider a test of the Copernican Principle through observations of the large-scale structures, and for this purpose we study the self-gravitating system in a relativistic huge void universe model which does not invoke the Copernican Principle. If we focus on the the weakly self-gravitating and slowly evolving system whose spatial extent is much smaller than the scale of the cosmological horizon in the homogeneous and isotropic background universe model, the cosmological Newtonian approximation is available. Also in the huge void universe model, the same kind of approximation as the cosmological Newtonian approximation is available for the analysis of the perturbations contained in a region whose spatial size is much smaller than the scale of the huge void: the effects of the huge void are taken into account in a perturbative manner by using the Fermi-normal coordinates. By using this approximation, we derive the equations of motion for the weakly self-gravitating perturbations whose elements have relative velocities much smaller than the speed of light, and show the derived equations can be significantly different from those in the homogeneous and isotropic universe model, due to the anisotropic volume expansion in the huge void. We linearize the derived equations of motion and solve them. The solutions show that the behaviors of linear density perturbations are very different from those in the homogeneous and isotropic universe model.

A second test was performed for 492 babies in whom blood IRT levels were found greater than 900 μg/l; retesting revealed persistent elevation in 55. Sweat testing confirmed cystic fibrosis in 43 babies, but results were normal in 12. During the course of this study, a total of 51 cystic fibrosis babies were identified: 43 by newborn screening, 6 because they had meconium ileus; so, early diagnosis was achieved in 49 cases out of 51. Two newborn babies did not have elevated IRT and they were missed by the screening test. Our results confirm that elevated blood IRT is characteristic of newborn babies with cystic fibrosis and show that this test has an excellent specificity (99.7%) and a good sensitivity (95%) when used as a neonatal screening test [fr

    Congenital cystic adnomatoid malformation (CCAM) is rare pulmonary cystic disease. CCAM has been detected on prematurity, stillborn and respiratory distress infant or child by chest X-ray film and CT scan. One case of CCAM diagnosed in utero at gestational age 22 weeks is reported with sonographic findings and autopsy findings. Ultrasonographic findings are large cystic lesion in fetal thorax and fetal hydrops without hydramnios. The survival of these infants is very poor despite accurate prenatal diagnosis and maximal postnatal care

    Fibroadenoma is the most common breast tumor in adolescent and young women. Fibroadenomas that consist of sclerosing adenosis, papillary apocrine metaplasia, epithelial calcifications, and/or cysts greater than 3 mm are considered as complex fibroadenoma. The relative risk of developing breast cancer in patients with complex fibroadenoma is increased, compared to women with noncomplex fibroadenoma. Extensive cystic degeneration in a fibroadenoma, so called "cystic fibroadenoma" is very rare. Herein, we present a case of such a lesion in a 43-year-old female who has been on follow-up for fibrocystic changes of the breast, and discuss both radiological and histopathologic differential diagnosis of this lesion with other cystic lesions of the breast, including cystic papilloma. The patient is free of disease after 17 months of clinical follow-up.

    2011-01-01

    Full Text Available Traditional approach to cystic fibrosis patients treatment doesn’t involve upper respiratory tract assessment, though abnormal changes — consequences of the cystic fibrosis transmembrane conductivity regulator gene mutation- do affect nasal and paranasal mucosa to the same extent. Approximately half of cystic fibrosis patients suffer from chronic rhinosinusitis and/or nasal polyposis that worsens the clinical course of already severe disease. Chronic hyperplasia in paranasal cavities can be quite extensive, recurrent and can lead to destruction of osseous walls of the cavity and of nasal septum. Thus increasing the amount of hospital admissions and and their duration. Low awareness of ENT-specialists working in polyclinics and in hospitals of ENT-pathology in cystic fibrosis patients leads to belated diagnostics, excessive manipulations, ineffective treatment, including surgery. All these lays grounds to implication of the early screening diagnostic program and development of proper treatment methods of ENT-complications of cystic fibrosis — therapeutic as well as surgical, with strict specification of indications and contraindications. Key words: cystic fibrosis, chronic rhino sinusitis, nasal polyposis. (Voprosy sovremennoi pediatrii — Current Pediatrics. — 2011; 10 (5: 49–53.

  15. Cystic Odontoma in a Patient with Hodgkin’s Lymphoma

    2015-01-01

    Full Text Available Cystic odontoma is a rare entity, which is characterized by the association of a cyst with complex/compound odontoma. The aim of this study was to report the case of a 5-year-old male patient diagnosed previously with Hodgkin’s lymphoma and treated successfully with chemotherapy and radiotherapy, who developed a mandibular odontogenic lesion. Physical examination revealed a swelling on the right side of the mandible. Radiographically, a well-defined radiolucent area surrounded by radiopaque material was observed. An incisional biopsy was performed and microscopic analysis showed a cystic lesion consisting of an atrophic epithelium comprising 2-3 cell layers and the absence of inflammation in the cystic capsule. The cyst was decompressed and the lesion was removed after 3 months of follow-up. Microscopic analysis of the surgical specimen showed a cystic hyperplastic epithelium surrounded by an intense chronic inflammatory cell infiltrate, which was in close contact with mineralized tissue resembling dentin and cementum. The final diagnosis was cystic odontoma. Since chemotherapy can affect the growth and development of infant teeth, a relationship between chemotherapy-associated adverse events and cystic odontoma is suggested in the present case.

    Neuroblastoma is the most common neonatal malignant tumor. Hemorrhage and necrosis are usual features of this lesion, but it rarely presents a totally cyst form. We report a case of cystic neuroblastoma detected on prenatal ultrasound and stress the need to include it in the differential diagnosis of cystic abdominal masses in the newborn. Ultrasound is the method of choice for assessing abdominal masses in children. However, magnetic resonance has been shown to be more advantageous for the study and follow-up of neuroblastomas.

    Patients diagnosed with retroperitoneal sarcoma at the Hospital San Juan de Dios were characterized during the years 2007 to 2012. The population framework was taken from the hospital's Pathology service database. A total of 15 patients older than 12 years with a diagnosis of sarcoma or malignant fibrous histiocytoma and that the site of origin of the biopsy was the retroperitoneum were selected. The data of the selected patients were collected through a data collection form. The variables included were: age, sex, origin, dates of importance (income, discharge, surgery, complication), presence and type of complications, pathological staging, type of surgery, comorbidities, presence and date of recurrence, treatment with chemotherapy and radiotherapy, death and causes of death. A descriptive analysis with the calculation of frequency measurements (absolute and relative) was carried out to describe the occurrence of the event. The analysis of proportional risks was performed considering the relationship between death and time, the possible relationship with the service of approach, clinical stage and resection status was also assessed. Information on diagnosis, evaluation, staging and management of retroperitoneal sarcomas is cited in the theoretical framework [es

    The goal of this study was to determine the risk of malignancy of thyroid nodules with minimal cystic changes. A total of consecutive 1,000 thyroid nodules (≥1 cm) with final diagnoses from two institutions were included in this study. The risk of malignancy of thyroid nodules was analyzed according to the internal content, which was categorized as purely solid, minimally cystic (cystic changes ≤10%), and partially cystic (cystic changes >10%). We also assessed the risk of malignancy of nodules with minimal cystic changes depending on echogenicity and presence of any suspicious ultrasonografic (US) features. The overall frequency of purely solid, minimally cystic, and partially cystic nodules was 730/1,000 (73%), 61/1,000 (6.1%), and 209/1,000 (20.9%), respectively, with risks of malignancy of 14.8% (108/730), 3.3% (2/61), and 3.3% (7/209), respectively. The risk of malignancy of nodules with minimal cystic changes was significantly lower than that of purely solid nodules (P=0.013). The risk of malignancy of nodules with minimal cystic changes was also lower than that of purely solid nodules in the group of hypoechoic nodules (P=0.063) and in the group of nodules with suspicious US features (P=0.028), but was not significantly different from that of partially cystic nodules regardless of echogenicity or the presence of suspicious US features (P≥0.652). Thyroid nodules with minimal cystic changes have a low risk of malignancy, similar to that of partially cystic nodules regardless of echogenicity or the presence of suspicious US features. The US lexicon could define solid nodules as nodules with purely solid internal content in order to enhance the accuracy of estimated risks of malignancy

    2017-03-01

    Full Text Available Paragangliomas are rare neuroendocrine tumours, most commonly found in adults. These differ from pheochromocytomas in that their location is extra-adrenal, and they are responsible for about 1% of arterial hypertension aetiologies. We report the case of a 30-year-old female whose past medical history was unremarkable. However, her arterial hypertension led to further examination in search of secondary aetiologies, in which a retroperitoneal mass and an increase in levels of catecholamines were detected; findings that led to the final diagnosis of paraganglioma. A multidisciplinary team, whose approach was to use pharmacological alpha-adrenergic blocking agents and a surgical resection of the lesion, treated the patient. The patient is clinically well but will continue to be monitored as an outpatient, and genetic testing is being encouraged.

    1986-07-01

    A 50-year-old Chinese man was found by ultrasound and computed tomography to have a retroperitoneal mass in the right upper quadrant of the abdomen. At operation, a hemorrhagic cyst was detected at the upper pole of the right kidney adjacent to the adrenal gland. Microscopic examination revealed that the cyst wall was composed of granulomatous tissue loaded with eggs and cross-sections of parasites, identified as Dioctophyma renale. The eggs were characterized by a birefringent striated double wall. The presence of cross sections of adult worms of D. renale in human tissue has not been previously described. Another unique feature of this case was that the right kidney was intact, as examined grossly at laparotomy and by intravenous pyelography. Eggs were not detected in the urine.

    We retrospectively reviewed MRI findings of 17 patients with 3 histologically proven cystic pituitary tumors. They consisted of 10 cystic pituitary adenomas, 4 craniopharyngiomas and 3 Rathke`s cleft cysts. We analyzed the following MRI parameters such as cyst wall appearance, enhancement pattern of cyst wall, location of residual pituitary gland and location of tumor. They were clinically significant parameters for histological differentiation. Even though combinations of such MRI parameters helped for more accurate preoperative diagnosis, the differentiation between craniopharyngioma and Rathke`s cleft cyst was difficult in some cases.

  8. Diagnostic Value of Multislice Computed Tomography and Magnetic Resonance Imaging in the Diagnosis of Retroperitoneal Spread of Testicular Cancer: A Literature Review

    International Nuclear Information System (INIS)

    Hansen, J.; Jurik, A.G.

    2009-01-01

    Testicular cancer is the most frequent malignant disorder in men aged 15-35 years. Generally, diagnosing and follow-up include computer tomography (CT) examinations to detect possible retroperitoneal spread (abdomen and pelvis), resulting in at least eight CT examinations. This patient group is thereby exposed to a non-neglectable radiation dose, increasing the risk of future radiation-induced secondary cancer. This is especially problematic in potentially surgically cured patients with stage 1 testicular cancer. Thus, it can be beneficial to substitute CT with magnetic resonance imaging (MRI), provided there is valid evidence that the diagnostic value of MRI is at least comparable to current multislice CT (MSCT). The purpose of this study was to analyze whether there is evidence to recommend a substitution of MSCT with MRI in the diagnosis of retroperitoneal spread of testicular cancer. A literature search on the diagnostic accuracy, specificity, and sensitivity of MSCT and MRI in the diagnosis of retroperitoneal spread of testicular cancer was performed in the following databases: PubMed, EmBase, and ISI Web of Science. The search was limited to include the period from 2000 to September 2008, and to human and English-language publications. Forty-four publications were obtained for formal review (27 from PubMed, 15 from EmBase, two from ISI Web of Science). None of the publications reviewed encompassed diagnostic specificity and sensitivity of MSCT, and they lacked systematic comparison of MSCT and MRI. Only one study included sensitivity and specificity of MRI compared to single-slice CT. Both methods had a sensitivity and a specificity of approximately 70%. The literature review did not reveal valid data regarding diagnostic accuracy of MRI compared with MSCT for diagnosing retroperitoneal spread of testicular cancer. A prospective blinded comparative study is needed to provide valid evidence

    2012-01-01

    Full Text Available Here we report an incidental huge uterine-cervical diverticulum from a total abdominal hysterectomy specimen in a perimenopausal woman who presented with acute abdominal pain. The diverticulum was mimicking with various cysts present in the lateral side of the female genital tract. Histopathological examination confirmed this to be a cervical diverticulum with communication to uterine cavity through two different openings. They can attain huge size if left ignored for long duration and present a diagnostic challenge to clinicians, radiologists, as well as pathologists because of its extreme rarity. Therefore, diverticula should also be included as a differential diagnosis. Its histopathological confirmation also highlights that diverticula can present as an acute abdomen, requiring early diagnosis with appropriate timely intervention. Immunohistochemistry CD 10 has also been used to differentiate it from a mesonephric cyst.

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck.

    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    Context Cystic fibrosis (CF) is the most widespread autosomal recessive genetic disorder that limits life expectation amongst the Caucasian population. As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator). The hepatic manifestations include particular changes referring to the basic CFTR defect, iatrogenic lesions or consequences of the multisystem disease. Even though hepatobiliary disease is the most common non-pulmonary cause ofmortalityin CF (the third after pulmonary disease and transplant complications), only about the 33%ofCF patients presents clinically significant hepatobiliary disease. Conclusions Liver disease will have a growing impact on survival and quality of life of cystic fibrosis patients because a longer life expectancy and for this it is important its early recognition and a correct clinical management aimed atdelaying the onset of complications. This review could represent an opportunity to encourage researchers to better investigate genotype-phenotype correlation associated with the development of cystic fibrosis liver disease, especially for non-CFTR genetic polymorphisms, and detect predisposed individuals. Therapeutic trials are needed to find strategies of

    Recognition of the congenital cystic masses of the face and neck is important because they are usually benign, and can be completely cured by surgical excision. We retrospective analyzed CT scan of 18 surgically proven congenital cystic masses of the face and neck. The cases included 5 thyroglossal duct cysts, 4 cystic hygromas, 5 dermoid cysts, 1 branchial cleft cyst, and 3 fissural cysts of the face. Of five cases of thyroglossal duct cysts, CT showed either a well-marginated, rim enhancing unilocular cystic mass (n=3), or a diffuse but heterogeneous highly enhancing soft tissue mass (n=2). The latter two cases were confirmed later as infected thyroglossal duct cysts. Four cases of cystic hygromas were seen as either an irregularly-marginated (n=3) or a well-marginated (n=1) rim enhancing multiseptated cystic mass with a fluid-fluid level. Five cases of dermoid cysts appeared as well-marginated rim enhancing unilocular ovoid masses. The content of each mass was predominantly fluid in four cases, of which additional solid components were found in two, and interspersed fat globules in one. One case was composed of a homogeneous fatty density. One case of branchial cleft cyst was in the anterior triangle near the left mandibular angle, and appeared as a well-marginated enhancing cystic mass with a thick rim. In this case displacement of the adjacent structures was noted also. All three cases of fissural cysts of the face were seen as a well-marginated, rim enhancing cystic mass, causing a smooth pressure erosion of the adjacent bones. We conclude that CT is useful for the evaluation of the congenital cystic masses of the face and neck, because it can differentiate various forms of the congenital lesions and is able to clearly reveal the relation of the mass to the adjacent structures

The latter two cases were confirmed later as infected thyroglossal duct cysts. Four cases of cystic hygromas were seen as either an irregularly-marginated (n=3) or a well-marginated (n=1) rim enhancing multiseptated cystic mass with a fluid-fluid level. Five cases of dermoid cysts appeared as well-marginated rim enhancing unilocular ovoid masses. The content of each mass was predominantly fluid in four cases, of which additional solid components were found in two, and interspersed fat globules in one. One case was composed of a homogeneous fatty density. One case of branchial cleft cyst was in the anterior triangle near the left mandibular angle, and appeared as a well-marginated enhancing cystic mass with a thick rim. In this case displacement of the adjacent structures was noted also. All three cases of fissural cysts of the face were seen as a well-marginated, rim enhancing cystic mass, causing a smooth pressure erosion of the adjacent bones. We conclude that CT is useful for the evaluation of the congenital cystic masses of the face and neck, because it can differentiate various forms of the congenital lesions and is able to clearly reveal the relation of the mass to the adjacent structures.

    The benign cystic peritoneal mesothelioma (BCPM) is a rare neoplasm affecting mainly females at reproductive age. The natural history and physiopathology of the BCPM are not entirely known. It is mainly characterized by the lack of malignant elements, no tendency to metastasis and by a pervasive tendency to generate local recurrences after surgical removal. The clinical manifestations are insidious, uncharacteristic; the benign cystic peritoneal mesothelioma is often discovered during a surgical procedure addressing another condition. Imaging tests can raise the suspicion of BCPM but the diagnostic can only be confirmed by histopathological examination corroborated with an immunohistochemical analysis. There are no long term studies dictating a single therapeutic attitude but a high risk of local recurrences and the possibility of transformation into malignant mesothelioma have lead to the current tendency towards an aggressive treatment of the tumor. We present the case of a recurrent benign cystic peritoneal mesothelioma in a 40 years old female patient, emphasizing the therapeutic approach and the role of radical surgery in the treatment of BPCM.

    Physical exercise training may form an important part of regular care for people with cystic fibrosis. This is an update of a previously published review. To assess the effects of physical exercise training on exercise capacity by peak oxygen consumption, pulmonary function by forced expiratory volume in one second, health-related quality of life and further important patient-relevant outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search: 04 May 2017.We searched ongoing trials registers (clinicaltrials.gov and the WHO ICTRP). Date of most recent search: 10 August 2017. All randomised and quasi-randomised controlled clinical trials comparing exercise training of any type and a minimum duration of two weeks with conventional care (no training) in people with cystic fibrosis. Two authors independently selected studies for inclusion, assessed methodological quality and extracted data. The quality of the evidence was assessed using the GRADE system. Of the 83 studies identified, 15 studies which included 487 participants, met the inclusion criteria. The numbers in each study ranged from nine up to 72 participants; two studies were in adults, seven were in children and adolescents and six studies included all age ranges. Four studies of hospitalised participants lasted less than one month and 11 studies were outpatient-based, lasting between two months and three years. The studies included participants with a wide range of disease severity and employed differing levels of supervision with a mixture of types of training. There was also wide variation in the quality of the included studies.This systematic review shows very low- to low-quality evidence from both short- and long-term studies that in people

    Slow earthquakes are characterized by a wide spectrum of fault slip behaviors and seismic radiation patterns that differ from those of traditional earthquakes. However, slow earthquakes and huge megathrust earthquakes can have common slip mechanisms and are located in neighboring regions of the seismogenic zone. The frequent occurrence of slow earthquakes may help to reveal the physics underlying megathrust events as useful analogs. Slow earthquakes may function as stress meters because of th...

    Cortical-sparing adrenalectomy is a suitable treatment for hereditary and sporadic bilateral pheochromocytoma, in cases of low risk of malignancy, to reduce the possibility of adrenal insufficiency assuming the chance of local recurrence. The aim of the study is to analyze the functional results of partial adrenalectomy by retroperitoneal endoscopic approach in single-adrenal patients or patients requiring bilateral adrenalectomy. Prospective study between January 2015 and February 2016 including pheochromocytoma patients diagnosed with low risk of malignant mutations. All patients agreed to be included in the study. Experienced endocrine surgeons who have been trained in minimally invasive endocrine surgery performed the procedure using the same surgical technique. Demographic variables and clinical characteristics were collected, subsequently carrying out the descriptive analysis of the data. A total of 6 patients were registered, four associated with MEN type 2 syndrome and two in the context of VHL syndrome. Retroperitoneoscopic resection was performed without laparoscopic or open conversion and no postoperative complications; the average hospital stay was 2.5 days. Preservation of the functional cortex without corticosteroids was achieved in 5 (83%) of out 6 cases with a follow-up of 26.2 ± 6 months. Today, these 5 patients have a preserved adrenal function without hormone replacement. Cortical-sparing adrenalectomy by the retroperitoneal endoscopic approach, in expert hands, is safe and feasible for the treatment of hereditary and sporadic pheochromocytoma in a context of low malignancy, making it possible to avoid the need for corticoid replacement in most cases.

    Full Text Available Gene therapy is an alternative treatment for genetic lung disease, especially monogenic disorders such as cystic fibrosis. Cystic fibrosis is a severe autosomal recessive disease affecting one in 2500 live births in the white population, caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR. The disease is classically characterized by pancreatic enzyme insufficiency, an increased concentration of chloride in sweat, and varying severity of chronic obstructive lung disease. Currently, the greatest challenge for gene therapy is finding an ideal vector to deliver the transgene (CFTR to the affected organ (lung. Adeno-associated virus is the most promising viral vector system for the treatment of respiratory disease because it has natural tropism for airway epithelial cells and does not cause any human disease. This review focuses on the basic properties of adeno-associated virus and its use as a vector for cystic fibrosis gene therapy.

    Liposarcoma (LS) is a rare and heterogeneous group of malignant mesenchymal neoplasms exhibiting characteristics of adipocytic differentiation. Currently, radical surgical resection represents the most effective and widely used therapy for patients with abdominal/retroperitoneal LS, but the presence of contiguous essential organs, such as the kidney, pancreas, spleen, adrenal glands, esophagus or colon, as well as often reoccurrence of LS in A/RP calls for the enhancement of surgical techniques to minimize resection and avoid LS reoccurrences. Difficulty in detecting the margins of neoplasms due to their affinity to healthy fat tissue accounts for the high reoccurrence of LS within A/RP. Nowadays, the microscopic detection of margins is possible only by use of biopsy, and the minimization of surgical resection of healthy tissues is challenging. In this presentation we'll demonstrate the initial OCT results for the imaging and distinction of LS and normal human fat tissues and clear detection of tumor boundaries.

    Chronic loss of appetite in cystic fibrosis concerns both individuals and families. Appetite stimulants have been used to help cystic fibrosis patients with chronic anorexia attain optimal body mass index and nutritional status. However, these may have adverse effects on clinical status. The aim of this review is to systematically search for and evaluate evidence on the beneficial effects of appetite stimulants in the management of CF-related anorexia and synthesize reports of any side-effects. Trials were identified by searching the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, MEDLINE, Embase, CINAHL, handsearching reference lists and contacting local and international experts.Last search of online databases: 01 April 2014.Last search of the Cystic Fibrosis Trials Register: 08 April 2014. Randomised and quasi-randomised controlled trials of appetite stimulants, compared to placebo or no treatment for at least one month in adults and children with cystic fibrosis. Authors independently extracted data and assessed the risk of bias within eligible trials. Meta-analyses were performed. Three trials (total of 47 recruited patients) comparing appetite stimulants (cyproheptadine hydrochloride and megesterol acetate) to placebo were included; the numbers of adults or children within each trial were not always reported. The risk of bias of the included trials was graded as moderate.A meta-analysis of all three trials showed appetite stimulants produced a larger increase in weight z score at three months compared to placebo, mean difference 0.61 (95% confidence interval 0.29 to 0.93) (P children, appetite stimulants improved only two of the outcomes in this review - weight (or weight z score) and appetite; and side effects were insufficiently reported to determine the full extent of their impact. Whilst the data may suggest the potential use of appetite stimulants in treating anorexia in adults and children with cystic fibrosis

    We report an adult case of cystic lymphangioma treated with OK-432 (Picibanil). A case report and review of the literature concerning the use of OK-432 to treat cystic lymphangioma is presented. A 31-year-old woman developed a cystic lymphangioma four weeks post-partum. This was treated initially by aspiration, for diagnostic purposes. Investigation suggested that surgery would be challenging. A review of the literature demonstrated success with OK-432 in the treatment of this condition, although primarily in the paediatric population. This patient was successfully treated thus, and at the time of writing remained symptom free. A suggested management plan is outlined. Treatment with OK-432 is useful in the management of cystic lymphangiomas in adults and should be considered as first line treatment.

  10. Cystic fibrosis with normal sweat chloride concentration: case report

    2003-01-01

    Full Text Available Cystic fibrosis is a genetic disease usually diagnosed by abnormal sweat testing. We report a case of an 18-year-old female with bronchiectasis, chronic P. aeruginosa infection, and normal sweat chloride concentrations who experienced rapid decrease of lung function and clinical deterioration despite treatment. Given the high suspicion ofcystic fibrosis, broad genotyping testing was performed, showing a compound heterozygous with deltaF508 and 3849+10kb C->T mutations, therefore confirming cystic fibrosis diagnosis. Although the sweat chloride test remains the gold standard for the diagnosis of cystic fibrosis, alternative diagnostic tests such as genotyping and electrophysiologic measurements must be performed if there is suspicion of cystic fibrosis, despite normal or borderline sweat chloride levels.

    The purpose of this study is to analyze the clinical impact of radical nephrectomy on retroperitoneal liposarcoma near the kidney. Data of patients who underwent surgery for unilateral primary retroperitoneal liposarcoma near the kidney were retrospectively collected. Patients were divided into four groups according to whether they underwent nephrectomy and combined resection of other organs. Kaplan-Meier survival analysis was used to estimate disease-free survival and overall survival. Multivariable Cox analysis was used to analyze factors related to disease-free survival and overall survival. Nephrectomy (HR = 0.260, CI = 0.078-0.873, p = 0.029) had a beneficial effect on disease-free survival, while interaction model of nephrectomy*other organ resection (HR = 4.655, CI = 1.767-12.263, p = 0.002) showed poor disease-free survival. Other organ resection was not related to disease-free survival (HR = 1.543, CI = 0.146-16.251, p = 0.718). Operation method (p = 0.007) and FNCLCC grade (p free survival. While combined organ resection without nephrectomy group (HR = 1.604, CI = 0.167-15.370, p = 0.682) and radical nephrectomy with combined organ resection group (HR = 1.309, CI = 0.448-3.825, p = 0.622) did not show significant difference in disease-free survival from the mass excision only group, radical nephrectomy without combined organ resection group (HR = 0.279, CI = 0.078-0.991, p = 0.048) showed superior disease-free survival. Radical nephrectomy of unilateral primary retroperitoneal liposarcoma near the kidney has a beneficial effect on disease-free survival.

    Laparoscopic surgical procedures are increasing in scope and in variety. The benefits of decreased wound morbidity and pain have been well documented for multiple procedures that have traditionally required laparotomy. Although there are few controlled studies to document them, these benefits may be evident from simple clinical observation. Cystic disease of the liver is a condition that is treated largely for symptomatic reasons. The so-called noninvasive or radiographic guided methods of treatment for cystic disease of the liver are fraught with high recurrence rates. We present four cases of cystic disease of the liver treated laparoscopically, followed with pertinent discussion.

    BACKGROUND: Extra-adrenal paragangliomas of the retroperitonium are infrequently diagnosed. Their malignant behaviour cannot be predicted on initial clinical and histological assessment. These tumours have higher propensity for subsequent metastasis compared with pargangliomas at other sites. AIM: We aim to describe a case report of an incidental finding of left retroperitoneal paraganglioma in a young man who presented with right flank pain. We also aim to emphasize the importance of diagnosis and the malignant potential of these tumours. METHOD: Patient\\'s clinical notes, operative findings, imaging studies and laboratory investigations including histology results were reviewed. A literature search was done to look into the incidence, presentation, follow-up plan and treatment options for these tumours. CONCLUSION: Surgical resection is the only available curative option for extra-adrenal paragangliomas. Metastasis is observed years after surgery, hence long-term follow-up is required.

    Two dogs with signs of forebrain disease had hypodense lesions on computed tomography evaluation. Magnetic resonance imaging of the first dog showed a hypointense lesion on the T1-weighted scan and a hyperintense lesion on T2-weighted scanning. At surgery, both dogs had a primary cystic intracranial lesion, and the abnormal tissue adjacent to the cyst had histological features of meningioma. Each dog underwent whole brain irradiation after surgery, and 1 dog lived for 3 years after treatment. While uncommon, meningioma should be considered as a differential diagnosis in dogs with cystic intracranial lesions

    Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

    The most common cystic malformations of the neck are the result of abnormal embryogenesis involving the thyroglossal duct (TGD), lymphatic primordia and the branchial apparatus. When the basic embryology of these structures is considered, a reasonable differential diagnosis - and in some cases a definitive diagnosis - can be achieved based on the location and the imaging characteristics of the cystic mass.

    Aim: To evaluate whether apparent diffusion coefficient (ADC) measurements from diffusion-weighted imaging (DWI) can characterize or predict the malignant potential of cystic pancreatic lesions. Materials and methods: Retrospective review of the magnetic resonance imaging (MRI) database over a 2-year period revealed 136 patients with cystic pancreatic lesions. Patients with DWI studies and histological confirmation of cystic mass were included. In patients with known pancreatitis, lesions with amylase content of >1000 IU/l that resolved on subsequent scans were included as pseudocysts. ADC of cystic lesions was measured by two independent reviewers. These values were then compared to categorize these lesions as benign or malignant using conventional MRI sequences. Results: Seventy lesions were analysed: adenocarcinoma (n = 4), intraductal papillary mucinous neoplasm (IPMN; n = 28), mucinous cystic neoplasm (MCN; n = 9), serous cystadenoma (n = 16), and pseudocysts (n = 13). There was no difference between ADC values of malignant and non-malignant lesions (p = 0.06), between mucinous and serous tumours (p = 0.12), or between IPMN and MCN (p = 0.42). ADC values for low-grade IPMN were significantly higher than those for high-grade or invasive IPMN (p = 0.03). Conclusion: ADC values may be helpful in deciding the malignant potential of IPMN. However, they are not useful in differentiating malignant from benign lesions or for characterizing cystic pancreatic lesions.

    The main aim of this paper was to report reproducible method of lumbar spine access via a lateral retroperitoneal route. The authors conducted a retrospective analysis of the technical aspects and clinical outcomes of six patients who underwent lateral multilevel retroperitoneal interbody fusion with psoas muscle retraction technique. The main goal was to develop a simple and reproducible technique to avoid injury to the lumbar plexus. Six patients were operated at 15 levels using psoas muscle retraction technique. All patients reported improvement in back pain and radiculopathy after the surgery. The only procedure-related transient complication was weakness and pain on hip flexion that resolved by the first follow-up visit. Psoas retraction technique is a reliable technique for lateral access to the lumbar spine and may avoid some of the complications related to traditional minimally invasive transpsoas approach.

  4. Differential Diagnosis of Cystic Lymphangioma of the Pancreas Based on Imaging Features

    Directory of Open Access Journals (Sweden)

    Ting-Kai Leung

    2006-01-01

    Full Text Available Lymphangioma is a benign tumor, which is a consequence of lymphatic malformation with blockage of lymphatic flow. Most lymphangiomas occur in the neck and axillary region, and < 1% occur in the mesentery or retroperitoneum. Lymphangiomas arising from the pancreas are extremely rare. We report the case of a 34-year-old woman with cystic lymphangioma of the pancreas without major symptoms or signs. A 6 × 6 cm intra-abdominal cystic mass was incidentally revealed by sonography during a health examination. It is always a challenge to differentiate the lesion from other possible cystic-like pancreatic neoplasms. Differential diagnosis of cystic lymphangioma from other cystic-like tumors of the pancreas can be performed based on their imaging characteristics, including presence of septa, cystic or wall calcification, soft tissue, wall thickness, single or multiple loculation, and dilatation of the pancreatic duct. Post-gadolinium magnetic resonance imaging is excellent in defining the origin of intra-abdominal cystic mass and intracystic septa.

  5. The role of anaerobic bacteria in the cystic fibrosis airway.

    2016-11-01

    Anaerobic bacteria are not only normal commensals, but are also considered opportunistic pathogens and have been identified as persistent members of the lower airway community in people with cystic fibrosis of all ages and stages of disease. Currently, the role of anaerobic bacteria in cystic fibrosis lower airway disease is not well understood. Therefore, this review describes the recent studies relating to the potential pathophysiological role(s) of anaerobes within the cystic fibrosis lungs. The most frequently identified anaerobic bacteria in the lower airways are common to both cystic fibrosis and healthy lungs. Studies have shown that in cystic fibrosis, the relative abundance of anaerobes fluctuates in the lower airways with reduced lung function and increased inflammation associated with a decreased anaerobic load. However, anaerobes found within the lower airways also produce virulence factors, may cause a host inflammatory response and interact synergistically with recognized pathogens. Anaerobic bacteria are potentially members of the airway microbiota in health but could also contribute to the pathogenesis of lower airway disease in cystic fibrosis via both direct and indirect mechanisms. A personalized treatment strategy that maintains a normal microbial community may be possible in the future.

  9. Constructing Optimal Coarse-Grained Sites of Huge Biomolecules by Fluctuation Maximization.

    Science.gov (United States)

    Li, Min; Zhang, John Zenghui; Xia, Fei

    2016-04-12

    Coarse-grained (CG) models are valuable tools for the study of functions of large biomolecules on large length and time scales. The definition of CG representations for huge biomolecules is always a formidable challenge. In this work, we propose a new method called fluctuation maximization coarse-graining (FM-CG) to construct the CG sites of biomolecules. The defined residual in FM-CG converges to a maximal value as the number of CG sites increases, allowing an optimal CG model to be rigorously defined on the basis of the maximum. More importantly, we developed a robust algorithm called stepwise local iterative optimization (SLIO) to accelerate the process of coarse-graining large biomolecules. By means of the efficient SLIO algorithm, the computational cost of coarse-graining large biomolecules is reduced to within the time scale of seconds, which is far lower than that of conventional simulated annealing. The coarse-graining of two huge systems, chaperonin GroEL and lengsin, indicates that our new methods can coarse-grain huge biomolecular systems with up to 10,000 residues within the time scale of minutes. The further parametrization of CG sites derived from FM-CG allows us to construct the corresponding CG models for studies of the functions of huge biomolecular systems.

    Chemical dissolution and extracorporeal shock wave lithotripsy are promising new methods for the treatment of cholelithiasis without cholecystectomy. Nonsurgical defunctionalization of the gallbladder is now required to prevent recurrent stone formation. The authors consider cystic duct occlusion to be the first step. Ten domestic pigs underwent transcatheter electrocoagulation of the cystic duct via a cholecystostomy under fluoroscopic control. Stricture formation was followed by complete cystic duct occlusion in all ten cases. After a follow-up period ranging from 2 to 17 weeks (mean, 13 weeks), the animals were killed. Histologic studies demonstrated that complete obliteration of the cystic duct lumen was due to fibrous scar formation

    Full Text Available Objective: The aim of this study was to identify predictors of viable germ cell tumor (GCT in postchemotherapeutic residual retroperitoneal masses. Materials and Methods: The pertinent clinical and pathologic data of 16 male patients who underwent postchemotherapeutic retroperitoneal lymph node dissection (PC-RPLND at King Faisal Specialist Hospital and Research Centre between 1994 and 2005 were reviewed retrospectively. It was found that all patients received cisplatin-based chemotherapy for advanced testicular GCT. Results: Out of the 16 male patients, 2 (13%, 8 (50%, and 6 (37% had viable GCT, fibrosis, and teratoma, respectively. Ten (10 of the patients with prechemotherapeutic S1 tumor markers did not have viable GCT, and two of the six patients who had prechemotherapeutic S2 tumor markers have viable GCT. All tumor marker levels normalized after chemotherapy even in patients with viable GCT. Four patients had vascular invasion without viable GCT. Furthermore, four patients had more than 60% embryonal elements in the original pathology, but only 1 had viable GCT at PC-RPLND. Four of the five patients with immature teratoma had teratoma at PC-RPLND but no viable GCT; however, out of the four patients with mature teratoma, one had viable GCT and two had teratoma at PC-RPLND. Of the two patients with viable GCT, one had 100% embryonal cancer in the original pathology, prechemotherapeutic S2 tumor markers, history of orchiopexy, and no vascular invasion; the other patient had yolk sac tumor with 25% embryonal elements and 40% teratoma in the original pathology, and prechemotherapeutic S2 tumor markers. Conclusion: None of the clinical or pathological parameters showed a strong correlation with the presence of viable GCT in PC-RPLND. However, patients with ≥S2 may be at higher risk to have viable GCT. Further studies are needed to clarify this.

    Children with cystic fibrosis liver disease and portal hypertension are at risk of developing acute hepatic encephalopathy. Even in the presence of normal synthetic liver function these children may have porto-systemic shunting. We report a case of an adolosecent who had cystic fibrosis liver disease and presented with life threatening hepatinc encephalopathy. This case illustrates that it is necessary to consider an appropriate dietary regimen in adolosecents with liver disease to prevent hepatic decompensation. Copyright © 2012 Wiley Periodicals, Inc.

    Purpose: The aim of the study concerning congenital cystic lung malformations was to evaluate prenatal diagnoses postnatally to determine prognostic factors as well as to define optimized perinatal management. Materials and Methods: The study is based on 45 prenatal ultrasound examinations depicting fetal cystic lung lesions. 32 of the mothers had follow-up examinations. 5 pregnancies were terminated due to CCAM and additional malformations. Complete regression of the lesions was seen prenatally in 8 cases and postnatally in 5 children. Results: Surgical intervention due to respiratory insufficiency was necessary in 4 neonates. According to the imaging results, CCAM was present in 4 cases and sequestration in 7 patients. No correlation between the imaging findings and the surgical results was found in 3 children: One child suffered from rhadomyoid dysplasia, and in the case of the second child, a left-sided hernia of the diaphragm and additional sequestration were detected. The third child showed AV malformation. The cystic lesions of the 14 children operated upon were proven histologically. The degree of accuracy in the present study was high. Conclusion: Precise perinatal management is warranted in order to determine according to the clinical relevance surgical intervention and to prevent complications after the first year of life. This is performed during the neonatal period for respiratory insufficient neonates and within the first year of life for clinically stable children. (orig.)

    Full Text Available Cystic meningioma is a relatively rare condition, radiological appearance of the cystic-solid components of the mass may create a diagnostic dilemma. The presence of a cyst is not a common imaging feature and this makes it difficult to differentiate it from hemangioblastoma, craniopharyngioma, metastasis and gliomas. Cystic meningiomas are present more commonly in children. We present a 60 year old male who presented with seizures and frontal lobe signs. The lesion was suspected as glioma however, postoperative histopathological examination demonstrated as meningioma. Patient showed remarkable recovery after surgery. Complete cyst resection should be considered if it is technically feasible and safe.

    Microalgae are an emerging research field due to their high potential as a source of several biofuels in addition to the fact that they have a high-nutritional value and contain compounds that have health benefits. They are also highly used for water stream bioremediation and carbon dioxide mitigation. Therefore, the tiny microalgae could lead to a huge source of compounds and products, giving a good example of a real biorefinery approach. This work shows and presents examples of experimental...

    Cystic fibrosis is a common genetic disorder characterized by a severe lung inflammation and fibrosis leading to the patient's death. Enhanced angiogenesis in cystic fibrosis (CF) tissue has been suggested, probably caused by the process of inflammation, as similarly described in asthma and chronic bronchitis. The present study demonstrates an intrinsic pro-angiogenic status of cystic fibrosis airway epithelial cells. Microarray experiments showed that CF airway epithelial cells expressed several angiogenic factors such as VEGF-A, VEGF-C, bFGF, and PLGF at higher levels than control cells. These data were confirmed by real-time quantitative PCR and, at the protein level, by ELISA. Conditioned media of these cystic fibrosis cells were able to induce proliferation, migration and sprouting of cultured primary endothelial cells. This report describes for the first time that cystic fibrosis epithelial cells have an intrinsic angiogenic activity. Since excess of angiogenesis is correlated with more severe pulmonary disease, our results could lead to the development of new therapeutic applications

  19. MicroRNAs in the pathogenesis of cystic kidney disease.

    Phua, Yu Leng; Ho, Jacqueline

    2015-04-01

    Cystic kidney diseases are common renal disorders characterized by the formation of fluid-filled epithelial cysts in the kidneys. The progressive growth and expansion of the renal cysts replace existing renal tissue within the renal parenchyma, leading to reduced renal function. While several genes have been identified in association with inherited causes of cystic kidney disease, the molecular mechanisms that regulate these genes in the context of post-transcriptional regulation are still poorly understood. There is increasing evidence that microRNA (miRNA) dysregulation is associated with the pathogenesis of cystic kidney disease. In this review, recent studies that implicate dysregulation of miRNA expression in cystogenesis will be discussed. The relationship of specific miRNAs, such as the miR-17∼92 cluster and cystic kidney disease, miR-92a and von Hippel-Lindau syndrome, and alterations in LIN28-LET7 expression in Wilms tumor will be explored. At present, there are no specific treatments available for patients with cystic kidney disease. Understanding and identifying specific miRNAs involved in the pathogenesis of these disorders may have the potential to lead to the development of novel therapies and biomarkers.

    Five cystic mass lesions of the pancreas were exemined by MRI. Multiplocular fluid components were demonstrated as areas of various signal intensity in mucinous cystadenoma and cystadenocarcinoma. Gas within the cystic mass was noted in ductectatic mucinous cystadenocarcinoma. Honeycomb pattern and classification were not depicted in serous cystadenoma. Necrotic matter was demonstrated as area of lower signal than liver in pseudocyst. These results were then compared with CT and ultrasound and at present enhanced CT combined with ultrasound is more diagnostic than MRI for cystic mass lesions of the pancreas. (author)

    A case of a surgically confirmed cystic lymphangioma of the spleen is presented. Preoperative imaging consisted of US, contrast-enhanced CT and MRI, all showing a multiloculated lesion with small cystic cavities divided by thin septa, corresponding to dilated lymphatic spaces. Preoperative studies correlated well with the pathologic findings. Cystic lymphangioma of the spleen is a very rare condition and is usually solitary and asymptomatic. Large lymphangiomas may be an indication for splenectomy, since the risk of rupture is high even from minor abdominal trauma. Preoperative diagnosis may be achieved with correlated noninvasive imaging. (orig.)

    Background and purpose: To examine control rates for predominantly cystic craniopharyngiomas treated with intracavitary phosphorus-32 (P-32). Material and methods: 22 patients with predominantly cystic craniopharyngiomas were treated at Indiana University between October 1997 and December 2006. Nineteen patients with follow-up of at least 6 months were evaluated. The median patient age was 11 years, median cyst volume was 9 ml, a median dose of 300 Gy was prescribed to the cyst wall, and median follow-up was 62 months. Results: Overall cyst control rate after the initial P-32 treatment was 67%. Complete tumor control after P-32 was 42%. Kaplan-Meier 1-, 3-, and 5-year initial freedom-from-progression rates were 68%, 49%, and 31%, respectively. Following salvage therapy, the Kaplan-Meier 1-, 3-, and 5-year ultimate freedom-from-progression rates were 95%, 95%, and 86%, respectively. All patients were alive at the last follow-up. Visual function was stable or improved in 81% when compared prior to P-32 therapy. Pituitary function remained stable in 74% of patients following P-32 therapy. Conclusions: Intracystic P-32 can be an effective and tolerable treatment for controlling cystic components of craniopharyngiomas as a primary treatment or after prior therapies, but frequently allows for progression of solid tumor components. Disease progression in the form of solid tumor progression, re-accumulation of cystic fluid, or development of new cysts may require further radiotherapy or surgical intervention for optimal long-term disease control.

    Nutrition is thought to influence disease status in patients with cystic fibrosis (CF). This cross-sectional study sought to evaluate nutrient intake and anthropometric data from 64 adult outpatients with cystic fibrosis. Nutrient intake from food and supplements was compared with the Dietary Reference Intakes for 16 nutrients and outcomes influenced by nutritional status. Attention was given to vitamin D and calcium given potential skeletal implications due to cystic fibrosis. Measurements included weight, height, body composition, pulmonary function, and serum metabolic parameters. Participants were interviewed about dietary intake, supplement use, pulmonary function, sunlight exposure, and pain. The participants’ mean body mass index (±standard deviation) was 21.8±4.9 and pulmonary function tests were normal. Seventy-eight percent used pancreatic enzyme replacement for malabsorption. Vitamin D deficiency [25-hydroxyvitamin D (25OHD)<37.5 nmol/L] was common: 25 (39%) were deficient despite adequate vitamin D intake. Lipid profiles were normal in the majority, even though total and saturated fat consumption represented 33.0% and 16.8% of energy intake, respectively. Reported protein intake represented 16.9% of total energy intake (range 10%–25%). For several nutrients, including vitamin D and calcium, intake from food and supplements in many participants exceeded recommended Tolerable Upper Intake Levels. Among adults with cystic fibrosis, vitamin D deficiency was common despite reported adequate intake, and lipid profiles were normal despite a relatively high fat intake. Mean protein consumption was adequate, but the range of intake was concerning, as both inadequate or excessive intake may have deleterious skeletal effects. These findings call into question the applicability of established nutrient thresholds for patients with cystic fibrosis. PMID:18060897

    Mucocele of the cystic duct remnant is an uncommon hepatobiliary complication of a liver transplant. Current practice usually involves either excising the cystic duct, or incorporating the distal end of the transected cystic duct into the suture line of the biliary anastomosis to ensure drainage. We report a patient who developed cystic duct remnant mucocele after the latter approach was adopted. We believe that this is likely related to delayed anastomotic stricturing, which prevented draining from the remnant cystic duct. We also discuss the incidence, pathology, investigations, and treatment of this condition.

    The concentration of the canceroembryonal antigen (CEA) has been determined in vitro by the radioimmunological analysis of the blood plasma of 70 donors and 130 patients with malignant tumours of the intestine (6 persons), stomach (77), with relapsing gastric carcinoma (12), tumours of the pancreas (7), retroperitoneal space (18) and with inflammatory disease of the gastrointestinal tract (12). It is established that the radioimmunological test in vitro for CEA can be used not only for primary diagnosis of cancer of the rectum but also as a substantial supplement to the clinical diagnosis of carcinoma of the stomach and the pancreas. A relationship revealed between the rise in the content of CEA and the extent of malignancy provides additional information for correct diagnosing the stage of gastric carcinoma and a choice of an adequate method of treatment. Tolerance of the CEA level in the blood in retroperitoneal tumours and inflammatory diseases of the gastrointestinal tract may serve as a criterion for differential diagnosis of malignant newgrowths in the abdominal cavity.

    2014-06-01

    Pseudo-Bartter syndrome (PBS) describes an uncommon but well recognised complication of cystic fibrosis leading to hypochloraemic, hypokalaemic metabolic alkalosis. Pseudo-Bartter syndrome is usually seen at initial presentation or within the first two years of life in children with cystic fibrosis. Risk factors for development of PBS include warm weather conditions, severe respiratory or pancreatic disease and gastrointestinal losses (e.g. vomiting and diarrhoea). PBS is rare in older children and adolescents although epidemics have been associated with heat wave conditions in warmer climates. In this era of climate change, it is crucial that clinicians consider Pseudo-Bartter syndrome when patients with cystic fibrosis present unwell during summer. Copyright © 2014 Elsevier Ltd.

    An analysis of 136 cases of stomach cancer led to the determination of the role and place of gammatopography, echography, computerized X-ray tomography, angiography and laparoscopy in specified preoperative diagnosis of extraorganic spreading of primary tumors. The informative value and shortcomings of certain methods were shown. A high accuracy of the entire set of diagnostic procedures (94.8%) in the preoperative definition of stomach cancer involvement of the abdominal and retroperitoneal organs and tissues was emphasized

    The congenital cystic adenomatoid malformation (CCAM) of the newborn is a particular form among the cystic disorders of the lung. The clinical findings, illustrated by four cases, and especially the roentgenographic symptoms are typical. Different radiologic examinations, including the computertomography, are discussed. The differential diagnosis of the disease is various, and therefore a correct and on time diagnosis is necessary, because the prognosis of the patient depends on an adequate therapy. (orig.) [de

    Cystic change associated with pulmonary tuberculosis is rarely encountered, and few reports are available on the radiologic findings of pulmonary tuberculosis presenting as multiple cystic lesions associated with consolidation or bronchohematogenous nodules. The cystic lesions in our pulmonary tuberculosis patient occurred during steroid treatment without antituberculous chemotherapy and progressively increased in size, but subsequently became smaller after the initiation of antituberculous chemotherapy. Herein, we report the chest radiographic and computed tomographic findings of cystic change in pulmonary tuberculosis in an immunocompetent adult

    1988-10-01

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity.

    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Cystic adventitial degeneration is a rare non-atherosclerotic cause of peripheral arterial occlusive disease, mainly seen in young men without other evidence of vascular disease. Diagnosis will be established by clinical findings and by ultrasound or angiography and can be treated by excision or enucleation of the affected arterial segment or by percutaneous ultrasound-guided aspiration. However, the etiology of adventitial cysts remains unknown. We report a case of cystic adventitial degeneration showing a connection between the joint capsule and the adventitial cyst, supporting the theory that cystic adventitial degeneration may represent ectopic ganglia from adjacent joint capsules.

    We investigated whether it was possible to predict the prognosis of fetuses with cystic hygroma in early pregnancy based on the degree of neck thickening. We retrospectively analyzed 57 singleton pregnancies with fetuses with cystic hygroma who were examined before the 22nd week of pregnancy. The fetuses were categorized according to the outcome, structural abnormalities at birth, and chromosomal abnormalities. Here, we proposed a new sonographic predictor with which we assessed neck thickening by dividing the width of the neck thickening by the biparietal diameter, which is expressed as the cystic hygroma width/biparietal diameter ratio. The median cystic hygroma width/biparietal diameter ratio in the intrauterine fetal death group (0.51) was significantly higher than that in the live birth group (0.27). No significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the structural abnormalities group at birth and the no structural abnormalities group, and no significant difference in the median cystic hygroma width/biparietal diameter ratio was found between the chromosomal abnormality group and the no chromosomal abnormality group. We used receiver operating characteristic analysis to evaluate the cystic hygroma width/biparietal diameter ratio to predict intrauterine fetal death. When the cystic hygroma width/biparietal diameter ratio cut-off value was 0.5, intrauterine fetal death could be predicted with a sensitivity of 52.9% and a specificity of 100%. It is possible to predict intrauterine fetal death in fetuses with cystic hygroma in early pregnancy if cystic hygroma width/biparietal diameter ratio is measured. However, even if cystic hygroma width/biparietal diameter ratio is measured, predicting the presence or absence of a structural abnormality at birth or a chromosomal abnormality is difficult. © 2018 Japanese Teratology Society.

    More than 300 NMR examinations form the basis of the survey presented of the anatomy and topography of the retroperitoneal space. The examinations were done with the Siemens supraconducting magnet system 'Magnetom' (1.0 Tesla), with different planes of imaging chosen, according to clinical approaches (axial, sagittal, frontal). Sectional thicknesses varied between 5 and 10 mm. The spin-echo technique was applied, with repetition times between 0.3 and 2.0s, echo times between 30 and 150 ms. In addition, special means such as high-resolution coils and respiratory gating were applied, and also a contrast medium (gadolinium-DTPA). The possibilities of imaging are explained, referring to the pancreas, kidneys, adrenal glands, lymph nodes, aorta abdominalis, and vena cava inferior. (orig./MG) [de

    Cystic fibrosis, the most common inherited disease of white population, is a disease of CFTR channels, in which mucosal function of many organs especially respiratory tract is impaired. Decreased mucociliary clearance and accumulation of mucus in airways facilitates colonization of infectious microorganisms, followed by infection. Following chronic infection, persistent inflammation ensues, which results in airway remodeling and deterioration of mucociliary clearance and result in a vicious cycle. Here, it is hypothesized that cholera toxin (CT) could ameliorate symptoms of cystic fibrosis as CT could dilute the thickened mucus, improve mucociliary clearance and alleviate airway obstruction. CT strengthens immunity of airway mucosa and it could attenuates bacterial growth and reduce persistency of infection. CT also modulates cellular immune response and it could decrease airway inflammation, hinder airway remodeling and prevent respiratory deterioration. Thereby it is hypothesized that CT could target and ameliorate many of pathophysiologic steps of the disease and it explores new horizons in treatment of CF. Copyright © 2015 Elsevier Ltd.

    2013-03-01

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates

    Cystic Fibrosis is caused by mutations in the Cystic Fibrosis Transmembrane conductance Regulator (CFTR) gene resulting in abnormal protein function. Recent advances of targeted molecular therapies and high throughput screening have resulted in multiple drug therapies that target many important mutations in the CFTR protein. In this review, we provide the latest results and current progress of CFTR modulators for the treatment of cystic fibrosis, focusing on potentiators of CFTR channel gating and Phe508del processing correctors for the Phe508del CFTR mutation. Special emphasis is placed on the molecular basis underlying these new therapies and emerging results from the latest clinical trials. The future directions for augmenting the rescue of Phe508del with CFTR modulators is also emphasized. PMID:26097168

    This paper examines the capability of MR imaging in differentiating cystic lesions in the maxillomandibular region. MR imaging of 34 patients with cystic lesions in the maxillomandibular region was performed prospectively. After T1-weighted axial imaging, T1-weighted axial and sagittal/coronal imaging with Gd-DTPA and T2-weighted axial imaging was performed. The pathologic examinations of the cases showed 9 ameloblastomas, 13 odontogenic keratocysts, and 11 other types of cysts. MR differentiation between ameloblastoma and cysts was possible in all cases but one. MR images of ameloblastoma showed solid and cystic components, multilocularity, irregularly thickened walls, mural nodules, marked Gd-DTPA enhancement of the wall, and low T1-weighted signal fluids. MR differentiation between various kinds of cysts was difficult without information from conventional radiography, except odontogenic keratocysts. MR images of 17 keratocysts showed cystic patterns, regularly thin walls monolocular cysts, weak Gd-DTPA enhancement of the walls, and inhomogeneous intensity of the contents

    Full Text Available The calcifying cystic odontogenic tumor normally presents as apainless, slow-growing mass, involving both maxilla and mandible,primarily the anterior segment (incisor/canine area. It generallyaffects young adults in the third to fourth decades, with no genderpredilection. Computerized tomography images revealed importantcharacteristics that were not detected by panoramic radiography,such as fenestration, calcification and tooth-like structures. Thetypical microscopic feature of this lesion is the presence of variableamounts of aberrant epithelial cells, without nuclei, which arenamed “ghost cells”. In addition, dysplastic dentine can be foundand occasionally the cyst can be associated with an area of dentalhard tissue formation resembling an odontoma. The treatment forcalcifying cystic odontogenic tumor involves simple enucleationand curettage. The purpose of this article is to present two differentmanifestation of calcifying cystic odontogenic tumor in whichcomputerized tomography, associated to clinical features, servedas an important tool for diagnosis, adequate surgical planning andfollow-up of patients.

    Cystic fibrosis is the most common hereditary disorder among Caucasians. Most of the patients are diagnosed as children. However, some cases are going undiagnosed into adulthood and are then often misdiagnosed because the non-pediatricians do not know cystic fibrosis very well and do not consider this diagnosis in adult patients. We present the medical history of a woman, who was diagnosed with cystic fibrosis at the age of 39 years, although she had suffered from bronchiectasis, pancreatic insufficiency and liver cirrhosis since many years. Her medical history was long with some diagnosis, but because of her age nobody considered the final diagnosis. In adult patients with bronchiectasis, liver cirrhosis and pancreatic insufficiency in combination or with only one of these symptoms, cystic fibrosis should be included into the differential diagnosis.

    Significant progress has been achieved in developing precision therapies for cystic fibrosis; however, highly effective treatments that target the ion channel, CFTR, are not yet available for many patients. As numerous CFTR therapeutics are currently in the clinical pipeline, reliable screening tools capable of predicting drug efficacy to support individualized treatment plans and translational research are essential. The utilization of bronchial, nasal, and rectal tissues from individual cystic fibrosis patients for drug testing using in vitro assays such as electrophysiological measurements of CFTR activity and evaluation of fluid movement in spheroid cultures, has advanced the prediction of patient-specific responses. However, for precise prediction of drug effects, in vitro models of CFTR rescue should incorporate the inflamed cystic fibrosis airway environment and mimic the complex tissue structures of airway epithelia. Furthermore, novel assays that monitor other aspects of successful CFTR rescue such as restoration of mucus characteristics, which is important for predicting mucociliary clearance, will allow for better prognoses of successful therapies in vivo. Additional cystic fibrosis treatment strategies are being intensively explored, such as development of drugs that target other ion channels, and novel technologies including pluripotent stem cells, gene therapy, and gene editing. The multiple therapeutic approaches available to treat the basic defect in cystic fibrosis combined with relevant precision medicine models provide a framework for identifying optimal and sustained treatments that will benefit all cystic fibrosis patients.

    Cystic angiomatosis is a rare disorder with a poor prognosis. We describe a case of a 33-year-old woman who presented with longstanding bone pain, hemolytic anemia, and an enlarged spleen. Radiologically, multiple osseous lesions with a mixed pattern of lytic and sclerotic areas were seen within the shoulders, spine, and pelvis. On CT and MRI of the abdomen, the spleen was markedly enlarged, with internal hyperdense foci on non-contrast CT scan, corresponding to low signal intensity areas on all MR pulse sequences. After administration of contrast, a mottled enhancement pattern throughout the entire spleen was seen both on CT and MRI. Cystic angiomatosis was proven by histological analysis of a biopsy specimen of an involved vertebra and histopathological examination of the spleen after subsequent splenectomy. This is the first report of a patient with disseminated cystic angiomatosis with splenic involvement in which the MRI features differ from the previous reports. Instead of the usual pattern consisting of multiple well-defined cystic lesions, a diffuse involvement replacing the entire spleen, with heterogeneous signal intensities on T2-weighted images and heterogeneous enhancement pattern, was seen in our patient.

    To review the feasibility of introducing advanced retroperitoneal renal laparoscopic surgery (RRLS) to a paediatric urology division, using the mentorship-training model. Although the scope of practice in paediatric urology is currently adapting endoscopic surgery into daily practice, most paediatric urologists in North America have had no formal training in laparoscopic surgery. The study included four paediatric urologists with 3-25 years of practice; none had had any formal laparoscopic training or ever undertaken advanced RRLS. An experienced laparoscopic surgeon (the mentor) assisted the learning surgeons over a year. The initial phases of learning incorporated detailed lectures, visualization through videotapes and 'hands-on' demonstration by the expert in the technique of the standardized steps for each type of surgery. Over 10 months, ablative and reconstructive RRLS was undertaken jointly by the surgeons and the mentor. After this training the surgeons operated independently. To prevent lengthy operations, conversion to open surgery was planned if there was no significant progression after 2 h of laparoscopic surgery. Over the 10 months of mentorship, 36 RRLS procedures were undertaken in 31 patients (28 ablative and eight reconstructive). In all cases the mentored surgeons accomplished both retroperitoneal access and the creation of a working space within the cavity. The group was able to initiate ablative RRLS but the mentor undertook all the reconstructive procedures. After the mentorship period, over 10 months, 12 ablative procedures were undertaken independently, and five other attempts at RRLS failed. Although the mentored approach can successfully and safely initiate advanced RRLS in a paediatric urology division, assessing the laparoscopic practice pattern after mentorship in the same group of trainees is warranted. Ablative RRLS is easier to learn for the experienced surgeon, but reconstructive procedures, e.g. pyeloplasty, require a high degree

    Cystic fibrosis is the most common lethal autosomal recessive disorder in the Caucasian population. Although the survival rate in patients constantly improves, lung damage is still the major cause of morbidity and mortality in patients with cystic fibrosis. In clinical practice, evaluation of patients’ pulmonary state is made by combination of monitoring of lung function and more directly by assessing the lung structure in imaging studies. Studies showed that computed tomography findings are more sensitive as compared to the pulmonary function tests. Computed tomography can identify a wide range of morphological abnormalities in patients with cystic fibrosis, such as bronchiectasis (which is progressive, irreversible and probably the most relevant structural change in cystic fibrosis) peribronchial thickening, mucous plugging and many other disorders that occur in the course of the disease. Computed tomography has a crucial role in the assessment of pulmonary damage over time, detecting complications and monitoring treatment effects in patients with cystic fibrosis

    Cystic pancreatic neoplasms are often an incidental finding, the frequency of which is increasing. The understanding of such lesions has increased in recent years, but the numerous types of lesions involved can hinder differential diagnosis. They include, in particular, intraductal papillary mucinous neoplasms (IPMN), serous cystic neoplasms (SCN), and mucinous cystic neoplasms (MCN). Knowledge of their histological and radiological structure, as well as distribution in terms of localization, age, and sex, helps to differentiate such tumours from common pancreatic pseudocysts. Several types of cystic pancreatic neoplasms can undergo malignant transformation and, therefore, require differentiated radiological management. This review aims to develop a broader understanding of the pathological and radiological characteristics of cystic pancreatic neoplasms, and provide a guideline for everyday practice based on current concepts in the radiological management of the given lesions.

    Purpose To determine if 3-T magnetic resonance (MR) neurography-guided retroperitoneal genitofemoral nerve (GFN) blocks are safe and effective for the diagnosis of genitofemoral neuralgia. Materials and Methods Following institutional review board approval and informed consent, 26 subjects (16 men, 10 women; mean age, 42 years [range, 24-78 years]; mean body mass index, 28 kg/m 2 [range, 20-35 kg/m 2 ]) with intractable groin pain were included. By using a 3-T MR imaging system, intermediate-weighted turbo spin-echo pulse sequences, and MR-conditional needles, diagnostic MR neurography-guided GFN blocks were performed in the retroperitoneum. Outcome variables included technical success, procedure time, complications, and rates of positive and negative GFN blocks in association with therapeutic outcomes. For the assessment of a learning curve, Mann-Whitney test was used. P values ≤ .05 were considered to indicate a statistically significant difference. Results In 26 subjects, 30 retroperitoneal GFN blocks were performed. Twelve (40%) were performed with an anterior needle path, 12 (40%) with a lateral needle path, and six (20%) with a posterior needle path. GFN blocks were technically successful in 24 of 26 (92%) subjects, achieving appropriate scrotal anesthesia. No complications occurred. The time required for a GFN block was 40 minutes (range, 18-67 minutes). The rate of a successful GFN intervention after a positive GFN block was 88% (14 of 16). The rate of a successful intervention of an alternative target after a negative GFN block was 71% (five of seven). Conclusion Selective retroperitoneally directed MR neurography-guided GFN blocks are safe and effective with high technical success and positive effect on surgical decision making in patients with presumed genitofemoral neuralgia. © RSNA, 2017 Online supplemental material is available for this article.

  12. Conservative Treatment for Cystic Duct Stenosis in a Child

    Full Text Available Introduction. Few cases of common bile duct stenosis have been reported in the literature, and observations of strictures in the cystic duct are even more rare. Surgical cholecystectomy is the treatment needed in most cases of gallbladder hydrops. This paper describes the diagnosis and successful medical treatment of a rare pediatric case of cystic duct stenosis and gallbladder hydrops. Case Report. A formerly healthy one-year-old girl was admitted with colicky abdominal pain. Blood tests were normal, except for an increase in transaminases. Abdominal ultrasound excluded intestinal intussusception and identified a distended gallbladder with biliary sludge. MR cholangiography revealed a dilated gallbladder containing bile sediment and no detectable cystic duct, while the rest of the intra- and extrahepatic biliary tree and hepatic parenchyma were normal. This evidence was consistent with gallbladder hydrops associated with cystic duct stenosis. The baby was treated with i.v. hydration, corticosteroids, antibiotics, and ursodeoxycholic acid. Her general condition rapidly improved, with no further episodes of abdominal pain and normalization of liver enzymes. This allowed to avoid cholecystectomy, and the child is well 1.5 years after diagnosis. Conclusions. Although cholecystectomy is usually necessary in case of gallbladder hydrops, our experience suggests that surgical procedures can be avoided when the distension is caused by a cystic duct stenosis.

    Monitoring of pulmonary physiology is fundamental to the clinical management of patients with Cystic Fibrosis. The current standard clinical practise uses spirometry to assess lung function which delivers a clinically relevant functional readout of total lung function, however does not supply any visible or localised information. High Resolution Computed Tomography (HRCT) is a well-established current 'gold standard' method for monitoring lung anatomical changes in Cystic Fibrosis patients. HRCT provides excellent morphological information, however, the X-ray radiation dose can become significant if multiple scans are required to monitor chronic diseases such as cystic fibrosis. X-ray phase-contrast imaging is another emerging X-ray based methodology for Cystic Fibrosis lung assessment which provides dynamic morphological and functional information, albeit with even higher X-ray doses than HRCT. Magnetic Resonance Imaging (MRI) is a non-ionising radiation imaging method that is garnering growing interest among researchers and clinicians working with Cystic Fibrosis patients. Recent advances in MRI have opened up the possibilities to observe lung function in real time to potentially allow sensitive and accurate assessment of disease progression. The use of hyperpolarized gas or non-contrast enhanced MRI can be tailored to clinical needs. While MRI offers significant promise it still suffers from poor spatial resolution and the development of an objective scoring system especially for ventilation assessment.

    Intranodular ethanol injection has been used for the past 10 years as an efficient modality for treating patients with thyroid nodules. Several studies have reported the success of this therapy in autonomous and cystic nodules and, more recently, in cold benign nodules. To evaluate the efficacy of this therapeutic modality on the treatment of autonomous and cystic thyroid nodules. 42 patients (26 with cystic and 16 with autonomous nodules) were treated with ultrasound guided intranodular 99% ethanol injection and followed for 6 months. No major complications were observed during or after treatment, however, most of the patients reported slight to moderate pain and/or discomfort after the injection. Most of the nodules showed reduction after the treatment. Autonomous nodules had a mean reduction of 50.3% and cystic nodules of 69.3%. No significant differences in pretreatment serum total T3, total T4 or TSH were observed among the patients in the cystic group. Patients in the autonomous group with hyperfunctioning nodules showed a decrease in serum total T3, total T4 and an increase in serum TSH levels, hence, proving the effectiveness of this therapy. Intranodular ethanol injection is a safe and efficient treatment for autonomous and cystic nodules of the thyroid.

    This article describes the case of a 16-year-old boy with cystic fibrosis who presented with difficulty seeing in the dark. He had a history of bowel surgery at birth, and he developed cystic fibrosis liver disease and osteopenia during his teenage years. He always had good lung function. When his serum vitamin A level was checked, it was undetectable in sample. He was diagnosed with night blindness and commenced on high-dose vitamin A. His symptoms resolved within 3 days. However, it took over 1 year for his vitamin A level to return to normal. This case emphasizes the importance of monitoring vitamin levels in cystic fibrosis to detect deficiency and prevent long-term consequences, and it highlights the challenges encountered during the course of night blindness treatment.

    Full Text Available Retroperitoneal fibrosis (RPF is a rare disease characterized by the presence of fibroinflammatory tissue around the abdominal aorta and ureteral entrapment in most cases. Idiopathic RPF is frequently reported in association with autoimmune diseases; however, there have been few reports of idiopathic RPF associated with Hashimoto's thyroiditis. Here, we report a case of idiopathic RPF with Hashimoto's thyroiditis in a patient with a single functioning kidney, which was successfully treated by corticosteroid therapy and transient intraureteral stent insertion with a double-J catheter.

    2013-01-01

    Cystic fibrosis transmembrane conductance regulator (CFTR) functions as a channel that regulates the transport of ions and the movement of water across the epithelial barrier. Mutations in CFTR, which form the basis for the clinical manifestations of cystic fibrosis, affect the epithelial innate immune function in the lung, resulting in exaggerated and ineffective airway inflammation that fails to eradicate pulmonary pathogens. Compounding the effects of excessive neutrophil recruitment, the mutant CFTR channel does not transport antioxidants to counteract neutrophil-associated oxidative stress. Whereas mutant CFTR expression in leukocytes outside of the lung does not markedly impair their function, the expected regulation of inflammation in the airways is clearly deficient in cystic fibrosis. The resulting bacterial infections, which are caused by organisms that have substantial genetic and metabolic flexibility, can resist multiple classes of antibiotics and evade phagocytic clearance. The development of animal models that approximate the human pulmonary phenotypes—airway inflammation and spontaneous infection—may provide the much-needed tools to establish how CFTR regulates mucosal immunity and to test directly the effect of pharmacologic potentiation and correction of mutant CFTR function on bacterial clearance.

    Pelvic retroperitoneal pneumography (PRP) and pelvic computed tomography (CT) were performed on 33 patients with rectal carcinoma in order to compare the usefulness of the two diagnostic procedures in the preoperative assessment of local malignant extramural invasion. Six PRP-negative patients in whom no free air was visualized in the retroperitoneal space surrounding the mass, were all assessed as having extramural invasion by CT scan and all had histologic evidence of invasion. Of 27 PRP-positive patients in whom free air was seen surrounding the mass, 18 were diagnosed as having extramural invasion on CT, 15 of whom had histologic proof of invasion. In the remaining 9 PRP-positive patients, there was no evidence of extramural invasion on the CT scans, but 5 patients showed evidence of invasion histologically. PRP, when positive, had an unacceptably high rate of being false positive and was therefore unreliable in assessing extramural invasion, whereas CT was able to detect, to some extent, extramural invasion which PRP failed to demonstrate. Based on these findings, we conclude that CT is more useful than PRP in the preoperative assessment of extramural invasion of rectal carcinoma, but is of limited diagnostic value when negative.

    Full Text Available Abstract Introduction The presentation of cystic fibrosis is dependant upon which organs are affected. Common presentations include chronic respiratory infections and malabsorption. Patients with atypical disease tend to present late in childhood or as adults. Eye manifestations of cystic fibrosis are less well known. Case presentation A 14-year-old Caucasian boy presented with tiredness and difficulty seeing at night, over a period of 6 months. Good vision was only described in bright conditions. There was no history of jaundice, steatorrhea or diarrhoea. Conclusion This is the first reported case of newly diagnosed cystic fibrosis-related liver disease in a teenage boy, whose presenting symptom was night blindness secondary to vitamin A deficiency.

  1. A rare case of retroperitoneal malignant triton tumor invading renal vein and small intestine

    Full Text Available Introduction. Malignant Triton tumor is a very rare malignant peripheral nerve sheath tumor with rhabdomyosarcomatous differentiation. Most of those tumors occur in patients with von Recklinghausen’s disease or as a late complication of irradiation and commonly seen in the head, neck, extremities and trunk. Case report. We reported retroperitoneal malignant Triton tumor in a 57-year-old female patient. Skin lesions were not present, and there was no family history of neurofibromatosis or previous irradiation. The presented case is one of a few recorded in the specialized literature that occurs in the retroperitoneal space in sporadic form. In this case, tumor consisted of a multilobular mass was in close relation with the abdominal aorta and inferior vena cava and involved the renal vein with gross invasion of the small intestine. The patient underwent total resection of the tumor and left nefrectomy was performed. The small intestine 10 cm in length was also resected and end-to-end anastomosis was conducted. The postoperative course was uneventful and the patient was discharged from the hospital ten days after the surgery. Conclusion. Diagnostically, it is crucial to recognize this uncommon histological variant because malignant Triton tumor has a worse prognosis than classic malignant peripheral nerve sheath tumor does. The use of the immunohistochemistry is essential in making the correct diagnosis. Only appropriate pathological evaluation supported by immunostaining with S-100 protein and desmin confirmed the diagnosis. Aggressive surgical management treatment improves the prognosis of such cases with adjuvant radiotherapy.

    Cystic hygroma is a benign congenital malformation of the lymphatic system that occurs in infant or children younger than 2 years of age. Although cystic hygroma is well recognized in pediatric practice, it seldom presents de novo in adulthood. These are commonly present in head and neck but can be present anywhere. Cystic hygroma is very rare in adults, but it should be considered in the differential diagnosis of adult neck swellings. Patients presenting with a painless, soft, fluctuant, and enlarging neck mass should have a careful history and physical examination along with radiological imaging to assist with diagnosis. Surgical intervention is the treatment of choice for this rare condition. Here, we are reporting a case of cystic hygroma in a 32-year-old male patient in the neck region. The objectives of this case report are to discuss the clinical presentation, diagnosis, histopathological findings and management of this malformation.

    CT and US were carried out on 81 patients with hepatocellular carcinoma, 20 patients with cholangiocellular carcinoma and 94 patients with metastatic liver cancer. 1) Cystic degeneration was observed in one with hepatocellular carcinoma (1.2%), one with cholangiocellular carcinoma (5.0%) and 12 with metastatic liver cancer (12.8%) by US, but this change was observed in only 5 by CT (1,0,4, respectively). Metastatic liver cancer showed the highest incidence among these tumors. 2) The characteristics of cystic degeneration of the liver tumors were thickened wall and irregularity of the inner surface of the wall. 3) Judging from macroscopic and histopathological findings, liquefactive necrosis in the tumors was shown as ''echoluent'' area. We concluded that cystic degeneration was one of the important findings in metastatic liver cancer and that careful observation by US and CT avoided the confusion with other hepatic cystic diseases.

    Cystic fibrosis is the most common autosomal recessive disease in white populations, and causes respiratory dysfunction in the majority of individuals. Numerous types of respiratory muscle training to improve respiratory function and health-related quality of life in people with cystic fibrosis have been reported in the literature. Hence a systematic review of the literature is needed to establish the effectiveness of respiratory muscle training (either inspiratory or expiratory muscle training) on clinical outcomes in cystic fibrosis. This is an update of a previously published review. To determine the effectiveness of respiratory muscle training on clinical outcomes in people with cystic fibrosis. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials register comprising of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of most recent search: 17 April 2018.A hand search of the Journal of Cystic Fibrosis and Pediatric Pulmonology was performed, along with an electronic search of online trial databases up until 07 May 2018. Randomised controlled studies comparing respiratory muscle training with a control group in people with cystic fibrosis. Review authors independently selected articles for inclusion, evaluated the methodological quality of the studies, and extracted data. Additional information was sought from trial authors where necessary. The quality of the evidence was assessed using the GRADE system MAIN RESULTS: Authors identified 19 studies, of which nine studies with 202 participants met the review's inclusion criteria. There was wide variation in the methodological and written quality of the included studies. Four of the nine included studies were published as abstracts only and lacking concise details, thus limiting the information available. Seven studies were parallel studies and two of a cross-over design. Respiratory

Diagnosis of abdominal cystic echinococcosis was made by ultrasound. All patients received albendazole, 10-15 mg/kg/day. Epidemiological data, symptoms, number, location and outcome of the cysts, serology and treatment received were analyzed. The parameter used to assess treatment response was cyst changes evaluated by ultrasound follow up using the WHO-IWGE classification.A total of 28 patients (with 46 abdominal cysts were included in the cohort. Mean age at enrolment was 9.4 years and mean duration of follow-up, 23.8 months. All patients resided in rural areas and had had contact with dogs. The asymptomatic form of the disease was the most common presentation. All patients received albendazole (mean duration: 142.5 days, with low incidence of adverse events. Albendazole had a positive effect on most of the cysts. Surgery was performed in 13 patients.Treatment with albendazole for uncomplicated cystic echinococcosis cysts is safe and effective, and can potentially reduce the need for surgical intervention.

    The late histopathological effects of intraoperative radiotherapy (IORT) on retroperitoneal tissues, intestine, and bile duct were investigated in dogs. Fourteen adult foxhounds were subjected to laparotomy and varying doses (0-45 Gy) of IORT (11 MeV electrons) delivered to retroperitoneal tissues including the great vessels and ureters, to a loop of defunctionalized small bowel, or to the extrahepatic bile duct. One control animal received an aortic transection and reanastomosis at the time of laparotomy; another control received laparotomy alone. This paper describes the late effects of single-fraction IORT occurring 3-5 years following treatment. Dogs receiving IORT to the retroperitoneum through a 4 X 15 cm portal showed few gross or histologic abnormalities at 20 Gy. At doses ranging from 30-45 Gy, radiation changes in normal tissues were consistently observed. Retroperitoneal fibrosis with encasement of the ureters and great vessels developed at doses ≥30 Gy. Radiation changes were present in the aorta and vena cava at doses ≥40 Gy. A 30 Gy dog developed an in-field malignant osteosarcoma at 3 years which invaded the vertebral column and compressed the spinal cord. A 40 Gy animal developed obstruction of the right ureter with fatal septic hydronephrosis at 4 years. Animals receiving IORT through a 5 cm IORT portal to an upper abdominal field which included a defunctionalized loop of small bowel, showed few gross or histologic abnormalities at a dose of 20 Gy. At 30 Gy, hyaline degeneration of the intestinal muscularis layer of the bowel occurred. At a dose of 45 Gy, internal intestinal fistulae developed. One 30 Gy animal developed right ureteral obstruction and hydronephrosis at 5 years. A dog receiving 30 Gy IORT through a 5 cm portal to the extrahepatic bile duct showed diffuse fibrosis through the gastroduodenal ligament. These canine studies contribute to the area of late tissue tolerance to IORT. 7 refs., 3 figs., 5 tabs

    Spontaneous retroperitoneal hematoma (SRH) is a potentially fatal clinical entity requiring immediate recognition and intervention. The clinical records of 18-year-old and older patients admitted to the University Hospital Marqués de Valdecilla from 2003 to 2013 were reviewed. "Spontaneous" was defined as unrelated to trauma, invasive procedures or bleeding due to aortic aneurysm rupture. Thirty-four patients with SRH (44% were on anticoagulant drugs). One-third of cases had chronic renal insufficiency. Abdominal pain was the most common symptom both in anticoagulated and non-anticoagulated patients (80% in anticoagulated and 89% in non-anticoagulated patients). About one half of the patients developed shock. A CT scan was the most commonly performed diagnostic test, followed by abdominal ultrasound. Most cases were managed conservatively (80%). More than half of the patients (66%) restarted anticoagulation therapy after the acute event with a mean delay of 19 days (range 2-90 days). None of them suffered a new bleeding episode. Restarting the anticoagulation treatment after hematoma resolution seems to be a safe practice. There is an increasing frequency of SRH in non-anticoagulated patients.

    Individuals with cystic fibrosis are at increased risk of colorectal cancer (CRC) compared to the general population, and risk is higher among those who received an organ transplant. We performed a cost-effectiveness analysis to determine optimal CRC screening strategies for patients with cystic fibrosis. We adjusted the existing Microsimulation Screening Analysis-Colon microsimulation model to reflect increased CRC risk and lower life expectancy in patients with cystic fibrosis. Modeling was performed separately for individuals who never received an organ transplant and patients who had received an organ transplant. We modeled 76 colonoscopy screening strategies that varied the age range and screening interval. The optimal screening strategy was determined based on a willingness to pay threshold of $100,000 per life-year gained. Sensitivity and supplementary analyses were performed, including fecal immunochemical test (FIT) as an alternative test, earlier ages of transplantation, and increased rates of colonoscopy complications, to assess whether optimal screening strategies would change. Colonoscopy every 5 years, starting at age 40 years, was the optimal colonoscopy strategy for patients with cystic fibrosis who never received an organ transplant; this strategy prevented 79% of deaths from CRC. Among patients with cystic fibrosis who had received an organ transplant, optimal colonoscopy screening should start at an age of 30 or 35 years, depending on the patient's age at time of transplantation. Annual FIT screening was predicted to be cost-effective for patients with cystic fibrosis. However, the level of accuracy of the FIT in population is not clear. Using a Microsimulation Screening Analysis-Colon microsimulation model, we found screening of patients with cystic fibrosis for CRC to be cost-effective. Due to the higher risk in these patients for CRC, screening should start at an earlier age with a shorter screening interval. The findings of this study

    Cystic fibrosis, like primary ciliary dyskinesia, is an autosomal recessive disorder characterized by abnormal mucociliary clearance and obstructive lung disease. We hypothesized that genes underlying the development or function of cilia may modify lung disease severity in persons with cystic fibrosis. To test this hypothesis, we compared variants in 93 candidate genes in both upper and lower tertiles of lung function in a large cohort of children and adults with cystic fibrosis with those of a population control dataset. Variants within candidate genes were tested for association using the SKAT-O test, comparing cystic fibrosis cases defined by poor (n = 127) or preserved (n = 127) lung function with population controls (n = 3,269 or 3,148, respectively). Associated variants were then tested for association with related phenotypes in independent datasets. Variants in DNAH14 and DNAAF3 were associated with poor lung function in cystic fibrosis, whereas variants in DNAH14 and DNAH6 were associated with preserved lung function in cystic fibrosis. Associations between DNAH14 and lung function were replicated in disease-related phenotypes characterized by obstructive lung disease in adults. Genetic variants within DNAH6, DNAH14, and DNAAF3 are associated with variation in lung function among persons with cystic fibrosis.

    The purpose of this study was to determine the preoperative radiological characteristic and survival differences of glioblastoma multiforme (GBM) with and without cysts. Twenty-one GBMs were collected retrospectively; these tumors were pathologic confirmed as GBM. Based on the preoperative MR imaging, we compared the cystic GBMs with the noncystic GBMs according to the the tumor size, the tumor interface, the tumor wall thickness and peritumoral edema. Seven cases were classified as cystic GBMs and fourteen were noncystic GBMs. The cystic GBMs had a well-defined tumor interface, a less than 2 cm thickness of the tumor wall and less than 40 cm 3 thick peritumoral edema as compared to that of the noncystic GBMs. There was a statistically significant difference in age between the patients with cystic tumors and those with noncystic tumors. For the patients with cystic GBMs and noncystic GBMs, median survival time after surgery was 43.8 months and 12.5 months, respectively. The cystic GBMs had a well-defined tumor interface, a thin wall and minimal edema, as compared with that of the noncystic GBMs. The patients with cystic GBMs were significantly younger and they had more favorable survival outcomes than did the patients with noncystic GBMs

    To estimate the overall prevalence of complementary and alternative medicine use among children with cystic fibrosis, determine specific modalities used, predictors of use and subjective helpfulness or harm from individual modalities. Of 53 children attending the cystic fibrosis clinic in London, Ontario (100% recruitment), 79% had used complementary and alternative medicine. The most commonly used modalities were air purifiers, humidifiers, probiotics, and omega-3 fatty acids. Family complementary and alternative medicine use was the only independent predictor of overall use. The majority of patients perceived benefit from specific modalities for cystic fibrosis symptoms. Given the high frequency and number of modalities used and lack of patient and disease characteristics predicting use, we recommend that health care providers should routinely ask about complementary and alternative medicine among all pediatric cystic fibrosis patients and assist patients in understanding the potential benefits and risks to make informed decisions about its use.

    Poor nutrition occurs frequently in people with cystic fibrosis and is associated with other adverse outcomes. Oral calorie supplements are used to increase total daily calorie intake and improve weight gain. However, they are expensive and there are concerns they may reduce the amount of food eaten and not improve overall energy intake. This is an update of a previously published review. To establish whether in people with cystic fibrosis, oral calorie supplements: increase daily calorie intake; and improve overall nutritional intake, nutritional indices, lung function, survival and quality of life. To assess adverse effects associated with using these supplements. We searched the Cochrane Cystic Fibrosis Trials Register comprising references from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We contacted companies marketing oral calorie supplements.Last search: 18 October 2016. Randomised or quasi-randomised controlled trials comparing use of oral calorie supplements for at least one month to increase calorie intake with no specific intervention or additional nutritional advice in people with cystic fibrosis. We independently selected the included trials, assessed risk of bias and extracted data. We contacted the authors of included trials and obtained additional information for two trials. We identified 21 trials and included three, reporting results from 131 participants lasting between three months and one year. Two trials compared supplements to additional nutritional advice and one to no intervention. Two of the included trials recruited only children. In one trial the risk of bias was low across all domains, in a second trial the risk of bias was largely unclear and in the third mainly low. Blinding of participants was unclear in two of the trials. Also, in one trial the clinical condition of groups appeared to be unevenly balanced at baseline and in another trial there were

    Cystic fibrosis is an autosomal recessive disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator gene. This disorder produces a variable phenotype including lung disease, pancreatic insufficiency, and meconium ileus plus bilateral agenesis of the vas deferens causing obstructive azoospermia and male infertility. Preimplantation genetic diagnosis is an alternative that allows identification of embryos affected by this or other genetic diseases. We report a case of couple with cystic fibrosis; the woman had the I148 T mutation and the man had the Delta F508 gene mutation. The couple underwent in vitro fertilization, associated with preimplantation genetic diagnosis, and with subsequent selection of healthy embryos for uterine transfer. The result was an uneventful pregnancy and delivery of a healthy male baby. PMID:25993078

    Parental overprotection has often been clinically associated with the psychological maladjustment of children with a chronic disease. The purpose of this study was to examine parental care and overprotection in children with cystic fibrosis compared to healthy controls. Results indicated no differences in the level of parental care or overprotection between controls and children with cystic fibrosis. However, a number of significant correlations were found between parental care and overprotection and children's psychosocial functioning. In particular, positive correlations were found between parental overprotection and poor psychosocial functioning in children with cystic fibrosis, whereas, poor psychosocial functioning in healthy children was associated with lack of parental care. Parental overprotection and care appear to play important roles in the emotional and psychological functioning of healthy and chronically ill children.

    As life expectancy increases in patients with cystic fibrosis, it is important to pay attention to extra-pulmonary comorbidities. Several studies have shown signs of myocardial dysfunction in adult patients, but little is known about onset and development of these changes over time. In this prospective study, cardiac function in children with cystic fibrosis was compared to that of healthy children. 33 children, aged 3-12years, with cystic fibrosis were recruited from the Wilhelmina Children's hospital and 33 age-matched healthy children were selected from the WHISTLER study, a population-based cohort study. Measurements of lung function, arterial stiffness, and echocardiography (conventional measures and myocardial deformation imaging) were performed. There were no differences in anthropometrics, lung function and blood pressure between the two groups. The cystic fibrosis children had a higher arterial stiffness compared to the healthy children (pulse wave velocity respectively 5.76±0.57m/s versus 5.43±0.61m/s, p-value 0.049). Using conventional echocardiographic parameters for right ventricular function, Tricuspid Annular Plane Systolic Excursion) and Tissue Doppler Imaging, cystic fibrosis children had a reduced right ventricular systolic function when compared to the healthy children. After adjustment for lung function, global strains of both right and left ventricles were significantly lower in the cystic fibrosis group than in healthy children (linear regression coefficient 1.45% left ventricle, p-value 0.022 and 4.42% right ventricle, p-value cystic fibrosis children than in healthy controls. Our study suggests that already at a very young age, children with cystic fibrosis show an increased arterial stiffness and some signs of diminished both right and left ventricular function.

    A nonerosive form of rheumatoid arthritis (R.A.) was found in 62 patients out of 660 patients with R.A.. These 62 patients exhibit slowly progressive cystic changes in about the same joints in which usually erosions develop in classic R.A.. The E.S.R. is often low, half of the patients remained seronegative and there are 35 males and 27 females in the group. A smaller group of 15 out of these patients could be followed from a stage wherein the radiographs were normal to a stage of extensive cystic changes, over a period of at least 6 years. An attempt is made to delineate this group within the rheumatoid arthritis disease entity. (orig.) [de

    The recent commercial introduction of a method for detecting albumin in meconium makes screening for cystic fibrosis feasible for many hospitals. If the tests is adopted, confirmatory tests should be available. Quantitative analyses of sweat for sodium by flame photometry and for chloride by silver titration and ion-sleective electrodes are now used as confirmatory tests. We compare results of these confirmatory methods applied to presons with cystic fibrosis, respiratory disorders, or digestive disorders, and to control subjects.

    A 51-year-old man was referred to our hospital on May, 24, 1978, with complaints of lower abdominal pain, lower abdominal mass, constipation and pollakisuria. Physical examination revealed a lower abdominal tumor which was smooth, elastic soft and of childs' head size. IVP and urethrography revealed left nonvisualizing kidney, right hydronephrosis and deformity of bladder. CT scan revealed a large intrapelvic mass. Under the diagnosis of retroperitoneal tumor, operation was done on June, 29, 1978. Adhesive changes between the tumor, sacrococcyx and left internal iliac artery was so severe that the tumor could not be resected, and only biopsy-specimen was taken. Pathohistological diagnosis of the tumor was carcinoid tumor. He received postoperative radiation therapy with total dosis of 5000 rad in 5 weeks, and complete remission was obtained. Now, more than 5 years have passed after operation, no recurrence was detected. Carcinoid tumors are rare and generally are not radioeffective, but some cases without carcinoid syndrome, including our case, are radioeffective. So radiation therapy should be the second choice of treatment for carcinoid tumor. (author)

    It has been well known that angiosarcoma (AS), particularly scalp AS, metastasizes to the lungs with multiple air-filled cystic lesions on chest computed tomography scans. Pneumothorax, due to cystic lesion rupture into the pleural space, is frequent;however, we do not exactly know how rapidly the metastatic lesions spread to the lungs or what the exact pathogenetic mechanism for cystic metastasis is. According to our experience, the speed of disease progression in pulmonary metastasis is relatively fast and the entire lungs may be involved within two or three months. The infiltrating spindle cell tumors in the alveolar walls are tethering the adjacent alveolar spaces in order to form a dilated air-filled cystic lesion.

    Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more children with cystic fibrosis have acid neutralization durations during chemical clearance that fall outside the physiological range. Published reference value for acid neutralization duration during chemical clearance (determined using combined impedance/pH monitoring) was used to assess esophageal acid neutralization efficiency during chemical clearance in 16 children with cystic fibrosis (3 to chemical clearance exceeded the upper end of the physiological range in 9 of 16 (56.3%) children with and in 3 of 16 (18.8%) children without cystic fibrosis ( p =0.0412). The likelihood ratio for duration indicated that children with cystic fibrosis are 2.1-times more likely to have abnormal acid neutralization during chemical clearance, and children with abnormal acid neutralization during chemical clearance are 1.5-times more likely to have cystic fibrosis. Significantly more (but not all) children with cystic fibrosis have abnormally prolonged esophageal clearance of acid. Children with cystic fibrosis are more likely to have abnormal acid neutralization during chemical clearance. Additional studies involving larger sample sizes are needed to address the importance of genotype, esophageal motility, composition and volume of saliva, and gastric acidity on acid neutralization efficiency in cystic fibrosis children.

    The purpose of this study is to analyze the CT features of the cystic masses in the neck and to review differential diagnosis. We retrospectively reviewed and analyzed the CT findings of 22 histopathologically proved, cystic neck masses in regard to the location in fascial plane and relationship with adjacent organ. Of 22 cases, ten congenital cysts two ranulas, seven inflammatory lesions, and three solid tumors were included. Ten congenital cystic masses were located in typical locations as branchial cleft cyst (5) in mandibular angle, thyroglossal duct cyst (3) in visceral space embeded within the strap muscles, cystic hygroma (1) and cavernous hemangioma (1) in posterior cervical space with insinuating appearance. Two cases of ranula included one simple ranula localized in sublingual space and a plunging ranula extending to adjacent submandibular space. Seven cases of inflammatory lesions were characterized by multispatial locations and good contrast-enhancement of walls and adjacent tissue. Solid masses of low density mimicking cyst were two pleomorphic adenomas of submandibular gland and one neurilemmoma. It is considered that thorough analysis of the CT findings with attention to typical location, CT appearance, and the relationship with the adjacent structures usually leads to the correct diagnosis.

    Purpose The aim of the study was to evaluate the effect of phosphorus-32 colloid ([32P]) intracavitary irradiation on the treatment of patients with cystic craniopharyngiomas. Methods Twenty patients with predominantly cystic craniopharyngiomas were admitted from 1981 to 2006. Eleven patients had [32P] intracavitary irradiation by stereotactic injection or Ommaya cyst instillation as the primary treatment, and the remaining nine had the same internal irradiation as an adjuvant treatment after tumor resection. A calculated irradiation dose of 400~500 Gy per once was delivered to the cyst wall. Conclusion The patients were followed up ranging from 36 to 336 months; no operative morbidity or mortality was found from [32P] intracavitary irradiation. Fourteen patients (70%) had tumor progression and required further two to four times intracavitary irradiation. All 20 cases achieved tumor shrinkage or stabilization with effective outcome 3–6 months after the last [32P] therapy. For patients with cystic craniopharyngioma, [32P] administration by stereo-tactic injection or Ommaya cyst instillation is a safe and helpful option, which could improve the life quality, prolong the life span, and enhance the survival rate of cystic craniopharyngioma patients.

    To evaluate the radiological and clinical findings of congenital cystic neuroblastomas as compared with those of the cystic presentation of neonatal adrenal hemorrhage. We analyzed the US (n = 52), CT (n = 24), and MR (n = 4) images as well as the medical records of 28 patients harboring congenital cystic neuroblastomas (n = 16) and neonatal adrenal hemorrhagic pseudocysts (n = 14). The history of prenatal detection, location, size, presence of outer wall enhancement, internal septations, solid portion, calcification, turbidity, vascular flow on a Doppler examination, and evolution patterns were compared in two groups of cystic lesions, by Fischer's exact test. All (100%) neuroblastomas and three (21%) of the 14 hemorrhagic pseudocysts were detected prenatally. Both groups of cystic lesions occurred more frequently on the right side; 11 of 16 (69%) for neuroblastomas and 11 of 14 (79%) for hemorrhagic pseudocysts. The size, presence of solid portion, septum, enhancement, and turbidity did not differ significantly (p > 0.05) between the two groups of cystic lesions. However, tiny calcifications (n = 3) and vascular flow on color Doppler US (n = 3) were noted in only neuroblastomas. The cystic neuroblastomas became complex solid and cystic masses, and did not disappear for up to 90 days in the three following cases, whereas 11 of the 14 (79%) hemorrhagic pseudocysts disappeared completely and the three remaining (27%) evolved to calcifications only. Although the imaging findings of two groups of cystic lesions were similar, prenatal detection, the presence of calcification on initial images, vascularity on color Doppler US, and evolution to a more complex mass may all favor neuroblastomas

    Objective: To evaluate the value of diffusion-weighted imaging (DWI) on differential diagnosis of intracranial cystic lesions. Methods: Seventy-six patients with surgically and pathologically confirmed intracranial cystic lesions undergone conventional MRI, DWI and contrast enhanced MRI examination. The signal characteristics of intracranial cystic lesions on DWI were analysed retrospectively, the apparent diffusion coefficient (ADC) values of cystic areas were measured quantitatively. Results: Nineteen brain abscesses showed hyperintense signal on DWI. Among 34 brain tumors, 3 brain gliomas were hyperintense signal, 1 brain glioma was isointense signal and 1 metastasis was hyperintense signal; the other 29 brain tumors showed hypointense signal on DWI. The ADC values of all lesions were: (0.62 ± 0.15) x 10 -3 mm 2 /s in brain abscesses, (2.39 ± 0.78) x 10 -3 mm 2 /s in brain gliomas, (2.68 ± 0.40) x 10 -3 mm 2 /s in brain hemangioblastomas, (2.79 ± 0.79) x 10 -3 mm 2 /s in brain metastases, respectively. There were significant differences between the ADC values of brain abscess and the cystic or necrotic portions of brain glioma, hemangioblastoma, metastasis (P 0.05). Seven intracranial arachnoid cysts showed hypointense signal and 16 epidermoid cysts strikingly hyperintense signal on DWI. The ADC values of arachnoid cysts and epidermoid cysts were (2.96 ± 0.36) x 10 -3 mm 2 /s and (0.94 ± 0.13) x 10 -3 mm 2 /s respectively. There was significant difference between the ADC values of arachnoid cysts and epidermoid cysts (P<0.01). Conclusion: DWI and ADC values have important contribution to the differentiation of brain abscesses from cystic or necrotic tumors, intracranial cystic lesions showing hypointense signal on DWI can exclude brain abscess.

    Although microsurgery remains the first-line treatment, gross total resection of cystic craniopharyngeomas (CP) is associated with significant morbidity and mortality and the addition of external irradiation to subtotal resection proves to achieve similar tumor control. However, concern regarding long-term morbidity associated with external irradiation in children still remains. With this retrospective analysis, the authors emphasize intracavitary brachytherapy using phosphorus-32 (P-32) as a treatment option for children with cystic CP. Between 1992 and 2009, 17 children (median age 15.4 years; range 7-18 years) with cystic CP underwent intracavitary brachytherapy using P-32. Eleven patients were treated for recurrent tumor cysts; 6 patients were treated primarily. MR imaging revealed solitary cysts in 7 patients; 10 patients had mixed solid-cystic lesions (median tumor volume 11.1 ml; range 0.5-78.9 ml). The median follow-up time was 61.9 months (range 16.9-196.6 months). Local cyst control could be achieved in 14 patients (82 %). Three patients showed progression of the treated cystic formation (in-field progression) after a median time of 8.3 months (range 5.3-10.3 months), which led to subsequent interventions. The development of new, defined cysts and progression of solid tumor parts (out-of-field progression) occurred in 5 patients and led to additional interventions in 4 cases. There was neither surgery-related permanent morbidity nor mortality in this study. The overall progression-free survival was 75, 63, and 52 % after 1, 3, and 5 years, respectively. Intracavitary brachytherapy using P-32 represents a safe and effective treatment option for children harboring cystic CP, even as primary treatment. However, P-32 does not clearly affect growth of solid tumor parts or the development of new cystic formations. (orig.) [de

    Objectives: To evaluate the effectiveness of PET in differentiating malignant from benign pancreatic cystic tumors. Methods: Between 2009 and 2010, all patients with pancreatic cystic tumors who had PET, triple phase contrast computed tomography (CT) and endoscopic ultrasound (EUS) were reviewed. Clinicopathological characteristics and final histology were correlated with preoperative PET, CT and EUS to assess the value of each modality in detecting malignant from benign lesions for clinical decision-making. Results: Twenty of a total of 116 patients with pancreatic cystic tumors had 18F-FDG PET because of diagnostic difficulties after evaluation with conventional modalities. Sensitivity and specificity of PET in differentiating malignant from benign pancreatic cystic tumors were 100% and 93.75%, with an accuracy of 95%. PET had the best sensitivity, specificity and accuracy for detecting malignant cystic tumors compared with CT and EUS. In 5 cases, the PET results altered the treatment options completely to follow-up instead of surgery (n = 2), limited resection instead of Whipple's resection (n = 1), and surgery instead of follow-up (n = 2). Conclusions: PET is an accurate, non-invasive method to distinguish malignant from benign pancreatic cystic tumors and can be used as an adjunct to facilitate clinical decision making.

    Full Text Available Abstract Background Persistent dyspnea is a common finding in the cystic fibrosis patient that typically leads to further work up of an alternative pulmonary etiology. Adult cystic fibrosis patients; however, are growing in numbers and they are living into the ages in which coronary artery disease becomes prevalent. Coronary disease should be included in the consideration of diagnostic possibilities. Case presentation A 52-year-old white male with cystic fibrosis was evaluated for exertional dyspnea associated with vague chest discomfort. Diagnostic testing revealed normal white blood cell, hemoglobin and platelet count, basic metabolic panel, fasting lipid profile, HbA1c, with chest radiograph confirming chronic cystic findings unchanged from prior radiographs and an electrocardiogram that revealed sinus rhythm with left anterior fascicular block. Stress thallium testing demonstrated a reversible anteroseptal perfusion defect with a 55% left ventricular ejection fraction. Heart catheterization found a 99% occlusion of the left anterior descending artery extending into the two diagonal branches, with 100% obstruction of the left anterior descending artery at the trifurcation and 70% lesion affecting the first posterior lateral branch of the circumflex artery. Conclusion This case report represents the first description in the medical literature of a cystic fibrosis patient diagnosed with symptomatic coronary artery disease. Applying a standard clinical practice guide proved useful toward evaluating a differential diagnosis for a cystic fibrosis patient presenting with dyspnea and chest discomfort.

    Medical records and radiographs were retrospectively reviewed over a 3-year period (2012-2015) from dogs presented to a private dental referral practice. Medical records were evaluated for the diagnosis of impacted or embedded teeth. The identified dogs' radiographs were reviewed for the presence of radiographically significant cystic lesions that were associated with the impacted or embedded teeth. Radiographic criteria were established by the authors for the purposes of identifying cystic lesions in dogs of different breeds and sizes, using established indices from human dental pathology as a basis. When histopathology results were available, they were reviewed and reported. In this study, 136 dogs ranging in age from 3 months to 17 years were diagnosed with 213 unerupted teeth during the study period. There were 62 (29.1%) of the 213 radiographically apparent cystic lesions identified based on the criteria proposed in this study. In this study, 146 (68.5%) of the 213 unerupted teeth were identified as mandibular first premolar teeth. Histopathology was obtained on 28 (45.1%) of the 62 diagnosed cystic lesions. Dentigerous cysts accounted for 20 (71.4%) of the 28 cystic lesions. Brachycephalic breeds were overrepresented in this study. Boxer, pug, Shih Tzu, and Boston terrier dogs were most likely to present with cystic lesions associated with unerupted teeth. Seventeen (85%) of the 20 cases with a histopathologic diagnosis of dentigerous cyst were found within these 4 brachycephalic breeds.

    Quantitative immunoprecipitation and immunoradiometric assays have been developed for a protein present in the serum of cystic fibrosis homozygotes, and to a lesser extent in the serum of heterozygotes. When tested on a panel of sera from 14 cystic fibrosis patients, 29 heterozygotes and 23 controls, the immunoprecipitation assay allowed correct assignments to be made on 94% of occasions with one batch of antiserum and 95% with another. With the same panel of sera, the immunoradiometric assay allowed 94% correct assignments. It is suggested that such accuracy is the maximum that can be expected in the present state of knowledge of cystic fibrosis. (author)

    A 32-year-old female who suffered from abdominal pain underwent 18 F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) for the diagnostic workup of pelvic mass lesions. Cystic mass lesions in the bilateral ovaries showed wall thickening and intense hypermetabolism along the rim. In addition, multifocal intense hypermetabolic lymphadenopathies were seen in the left paraaortic lymph node (LN), aortocaval LN, and both common iliac LNs. We interpreted these findings as bilateral ovarian cancer with retroperitoneal metastatic lymphadenopathies rather than endometriosis with reactive lymphadenopathies rather than endometriosis with reactive lymphadenopathies. However, Histopathological examination confirmed the ovarian mass lesions as tubo-ovarian abscesses. We report a case that even if simultaneous hypermetabolic retroperitoneal LNs are seen, intense hypermetabolic lesions in both ovaries can be in consequence of inflammatory change

  19. A unique case of a huge mixed squamous cell and glandular papilloma of non-endobronchial origin with a peripheral growth

    Kei Yabuki

    Full Text Available We report a case of a huge solitary non-endobronchial pulmonary tumor in a 76-year-old male smoker. The tumor measured 11 × 10 × 8 cm. It was ill-defined, and it was located periphery of the right lower lobe with the subpleural cystic spaces. He underwent right lower lobectomy with mediastinal lymph node dissection and is free from tumor 30 months after surgery. Microscopically, it was composed of a proliferation of squamous and ciliated columnar epithelial cells with a few mucous cells. These cells were arranged in a papillary growth fashion extending along the fibrously thickened alveolar septa together with metaplastic bronchiolar and squamous epithelia displaying an usual interstitial pneumonia-pattern. Although the histologic features of the tumor were that of a mixed squamous cell and glandular papilloma (MSCGP, it was peripherally located and showed a lepidic growth, and it was much larger than previously reported MSCGPs. It is possible that the tumor developed in association with bronchial metaplasia in the periphery of the lung, and then extended along the surface of the reconstructed air spaces, which resulted in its unique histologic appearance. Further investigations of respiratory papilloma are needed to clarify the pathogenesis of these lesions.

    Adolescents with well-controlled cystic fibrosis, including good lung function and appropriate growth, commonly participate in competitive athletic activities. We present the case of an adolescent male with cystic fibrosis, hyponatremia, dehydration, and rhabdomyolysis after participating in football practice on a summer morning. The patient presented with severe myalgia and serum sodium of 129 mmol/L, chloride 90 mmol/L, and creatine phosphokinase 1146 U/L. Aggressive hydration with intravenous 0.9% saline resulted in clinical improvement with no renal or muscular sequelae. Health care providers need to educate patients with cystic fibrosis about maintaining adequate hydration and sodium repletion during exercise. Research is needed regarding the appropriate amount and composition of oral rehydration fluids in exercising individuals with cystic fibrosis, as the physiology encountered in these patients provides a unique challenge to maintaining electrolyte balance and stimulation of thirst.

    Full Text Available The electromyogram recorded from the diaphragm (EMGdi and parasternal intercostal muscle using surface electrodes (sEMGpara provides a measure of neural respiratory drive (NRD, the magnitude of which reflects lung disease severity in stable cystic fibrosis. The aim of this study was to explore perception of NRD and breathlessness in both healthy individuals and patients with cystic fibrosis. Given chronic respiratory loading and increased NRD in cystic fibrosis, often in the absence of breathlessness at rest, we hypothesised that patients with cystic fibrosis would be able to tolerate higher levels of NRD for a given level of breathlessness compared to healthy individuals during exercise. 15 cystic fibrosis patients (mean forced expiratory volume in 1 s (FEV1 53.5% predicted and 15 age-matched, healthy controls were studied. Spirometry was measured in all subjects and lung volumes measured in the cystic fibrosis patients. EMGdi and sEMGpara were recorded at rest and during incremental cycle exercise to exhaustion and expressed as a percentage of maximum (% max obtained from maximum respiratory manoeuvres. Borg breathlessness scores were recorded at rest and during each minute of exercise. EMGdi % max and sEMGpara % max and associated Borg breathlessness scores differed significantly between healthy subjects and cystic fibrosis patients at rest and during exercise. The relationship between EMGdi % max and sEMGpara % max and Borg score was shifted to the right in the cystic fibrosis patients, such that at comparable levels of EMGdi % max and sEMGpara % max the cystic fibrosis patients reported significantly lower Borg breathlessness scores compared to the healthy individuals. At Borg score 1 (clinically significant increase in breathlessness from baseline corresponding levels of EMGdi % max (20.2±12% versus 32.15±15%, p=0.02 and sEMGpara % max (18.9±8% versus 29.2±15%, p=0.04 were lower in the healthy individuals compared to the cystic

    From June 1980 to May 1993, 52 patients with a mean age of 49, underwent a retroperitoneal pelvic lymph node laparoscopy procedure for cervix carcinoma classified as stage IA (14), IB (12), IIA (6), IIB (14), IIIB(3), IVA (3). Two techniques were used: a retroperitoneoscopy in 16 cases and a panoramic retroperitoneal pelviscopy (PRPP) in 36 cases. The aim was to define, with a better accuracy, the pelvic lymph node status, to adapt the target volume, and to estimate the morbidity.More nodes were biopsied with PRPP than with retroperitoneoscopy (p<0.05). There was a disagreement between the conventional radiologic assessment and the histological results in 28.6%. Specificity is 100%. Intra-operative and post-surgical morbidity was equivalent in the two procedures. One grade 3 urinary late morbidity (3%) was observed among the 33 patients who underwent a pelvic external irradiation. There was no morbidity of the gastro-intestinal tract. Discussion deals with the support offered by the two laparoscopic procedures to define the pelvic lymph node status, to choose the planning target volume, and to precise the lymph node boost.

    To evaluate the efficacy of OK-432 solution for slerotheraphy of cystic lesions of the head and neck. Nineteen cystic lesions comprising ten plunging ranulas, three simple ranulas, three cystic lymphangiomas, one first branchial cleft cyst and two unknown supraclavicular cysts considered to be lymphangiomas were treated by sucking out as much liquid content as possible and then injecting the same volume of OK-432 solution under ultrasound guidance. Patients were followed up clinically and radiologically. Follow-up sonography or CT- performed after a mean interval of nine months showed total or near-total shrinkage of four plunging ranulas. However, six such lesions recurred in spite of more than one (mean, two) sclerotherapy sessions. In cases involving two simple ranulas at the floor of the mouth, failure resulted from extracystic leakage of OK-432 solution via the puncture site. Two unilocular cystic lymphangiomas completely regressed during the follow-up period (mean, seven months), but the multiocular type showed a 65% volume reduction after 12 months. A first branchial cleft cyst was markedly reduced in size, with only a small cystic portion remaining after eight months, follow-up. Two supraclavicular cysts with straw-color fluid did not respond to sclerotherapy. OK-432 sclerotherapy of macrocystic lymphangiomas is an effective and promising alternative to surgery. For other cysts, however, including plunging ranula, efficacy, varied, and 64% of such lesions recurred

    Full Text Available Malignant peripheral nerve sheath tumors (MPNSTs are nonrhabdomyosarcoma soft tissue sarcomas with rare occurrence in children specially in the retroperitoneum. We describe a young child who presented with an abdominal mass. Both ultrasound and computed tomography revealed a large right-sided abdominal mass in the anatomic place of right kidney, while no kidney or ureter was observed at that side. He underwent surgical resection of the tumor with a primary impression of Wilms tumor. To the authors’ knowledge, this is the first case of retroperitoneal malignant peripheral nerve sheath tumor and absent kidney. This case suggests the very rare probability of association of MPNSTs in children with genitourinary tract anomalies such as renal agenesis.

    Previous studies have suggested that the cystic change of pituitary adenoma might be related to the blood supply and metabolism of the tumor; however, the exact pathologic mechanism underlying the cystic change remains unknown. We aimed to assess the features of regional blood supply of pituitary adenoma and examine its relationship with the cystic change of pituitary adenoma. Patients (N = 79) with pituitary adenoma admitted to our hospital were divided into the parenchyma group (n = 40) or the cystic change group (n = 39). Dynamic contrast-enhanced magnetic resonance imaging of the pituitary adenoma was conducted for the parenchyma group and the steepest slopes (SS max , reflecting regional blood supply) at different areas were calculated. The location of cystic change of the pituitary adenoma was recorded and analyzed for the cystic change group. The parenchyma group showed an upper SS max of 2.52 ± 1.18, a lower SS max of 2.89 ± 1.46, a left SS max of 2.71 ± 1.31, and a right SS max of 2.66 ± 1.29. The difference between the upper and lower SS max was statistically significant (P supply is unevenly distributed in the parenchymal pituitary adenoma, with reduced blood supply in the upper than the lower region. Cystic change mainly occurs in the upper region of pituitary adenoma. Copyright © 2017 Elsevier Inc. All rights reserved.

    Cystic lesions of the pancreas encompass a broad spectrum of benign, premalignant, and malignant tumors which are primarily cystic or result from cystic necroses of solid neoplasms. Because of the wide use of cross-sectional imaging techniques they are increasingly being identified in asymptomatic patients as well as in patients presenting with abdominal pain, jaundice or pancreatitis. Among these lesions, intraductal papillary mucinous neoplasms, serous cystic neoplasms and mucinous cystic neoplasms represent the majority of cases. With increasing experience with these tumors, a refinement of our understanding of their morphology and of their natural course has emerged. It is important to be familiar with the CT and MR imaging features of these lesions to differentiate these tumors and to orient the diagnosis towards benign or malignant forms. Because characterization of cystic tumors of the pancreas can sometimes be difficult due to overlapping imaging features, additional criteria such as clinical symptoms, localization, age and gender have to be taken into account. If appropriately treated, these tumors can usually be cured by resection and the decreasing risk of pancreatic surgery has led to an increasing number of resections of pancreatic tumors. The management of cystic tumors of the pancreas has not yet been standardized and the correct evaluation and subsequent management of the disease in asymptomatic patients have not been fully defined.

    Full Text Available Intraductal papillary mucinous neoplasm (IPMN of the pancreas is an intraductal mucin-producing epithelial neoplasm that arises from the main and/or branched pancreatic duct. It usually presents as cystic lesion of pancreas. There are well known differential diagnosis of cystic pancreatic lesion. Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use of abdominal imaging. The diagnosis and treatment of intraductal papillary mucinous tumors (IPMN of the pancreas has evolved over the past decade. IPMN represents a spectrum of disease, ranging from benign to malignant lesions, making the early detection and characterization of these lesions important. Definitive management is surgical resection for appropriate candidates, as benign lesions harbor malignant potential. IPMN has a prognosis, which is different from adenocarcinoma of the pancreas. We report a case of a 58-year-old male with intraductal papillary neoplasm involving main duct and side branches presenting to us with clinical symptoms of chronic pancreatitis with obstructive jaundice and cholangitis treated surgically.

    Mucous retention cysts of the parotid gland are rare, and a coexistent adenoid cystic carcinoma is even an unusual occurrence. Such coexistent adenoid cystic carcinomas with mucous retention cyst of the parotid gland are difficult to diagnose clinically and, at times, stage difficulty in their management. We report a rare case of adenoid cystic carcinoma associated with mucous retention cyst of the parotid gland with its diagnostic and management dilemma in a 14-year-old adolescent girl.

    Full Text Available Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

    A cystic lesion in the lung is defined as a well-demarcated epithel-lined cavity, that can be mostly filled with air, water, as well as solid material content. This definition includes a wide variety of diseases such as bronchogenic cyst, abscess formation, lymphangioleiomyomatosis, Langerhans cell histiocytosis, emphysema, bronchiectasis, and pneumatoceles. Despite the difficulties in differential diagnosis, there are some diagnostic criteria for CT-scanning helping the radiologist to differentiate between these cystic entities. Moreover, clinical informations are extremely important. The most important clinical parameters include age, sex, clinical history and symptoms. Thus, a better understanding of classic CT appearance of cystic lung disease will allow more definitive diagnosis and could, in some cases, avoid biopsy. (orig.)

    Cystic fibrosis (CF) is a multi-systemic disease with major impact on the lungs. Pulmonary manifestation is crucial for the prognosis and life expectancy of patients. Imaging modalities and lung function tests reflect the pulmonary status in these patients. The standard imaging modality for diagnosis and follow-up of pulmonary changes is chest x-ray. The gold standard for the detection of parenchymal lung changes remains high resolution computed tomography (HRCT), but this is not used routinely for CF-patients due to radiation exposure. Magnetic resonance imaging (MRI) used to be of no importance in monitoring cystic fibrosis lung disease, as shown in studies from the 1980s and early 1990s. The continuing improvement of MRI techniques, however, has allowed for an adequate application of this non-radiation method in diagnosing the major pulmonary findings in CF, in addition to the assessment of lung function.

    Full Text Available Background: Cystic papillary thyroid carcinoma (CPTC is a variant of papillary carcinoma that has many mimickers in cytological grounds. Aim: To study the cytomorphologic features of CPTC and compare them to those of other cystic thyroid lesions using fine-needle aspiration cytology (FNAC. We also aimed to identify the cytomorphologic features that distinguish CPTC from other cystic thyroid lesions. Materials and Methods: Seventy-three cases of CPTC were included in the study. The cytomorphologic features of these cases were analyzed. The FNA smears of other thyroid lesions with cystic changes (300 colloid goiters, 290 adenomatoid nodules, 11 follicular neoplasms, and 9 hurtle cell neoplasm were also studied. Results: The smears in CPTC revealed isolated follicular cells, small groups of cells with scalloped margins, cell swirls, small clusters with a cartwheel pattern, papillary clusters, intranuclear inclusions, nuclear grooves, sticky colloid, intracellular colloids, psammoma bodies, multinucleated giant cells, and foamy and hemosiderin laden macrophages. Small groups of cells with scalloped borders, cellular swirls, and small clusters with a cartwheel pattern were seen in CPTC, but not in other cystic lesions. Interestingly, mesothelial-like cells and hemophagocytic cells were seen in five and three cases of CPTC, respectively, but not in other cystic lesions. Conclusion: Mesothelial-like cells and hemophagocytic cells were observed in five and three cases of CPTC, respectively. Similar finding have not been previously reported in the literature.

    Plasma lactoferrin levels have been determined by radioimmunoassay for the different weeks of normal pregnancy, in normal healthy adults and in children with and without cystic fibrosis. The lactoferrin levels were higher in pregnancy than in both male and female normal adults and showed a slight progressive increase up to week 29 and thereafter remained high. Five out of seven children with cystic fibrosis had markedly raised plasma lactoferrin levels from six to 16 times higher than the mean of a control group of children. (Auth.)

    The purpose of the study was to assess the incidence of insomnia in adolescents and young adults with cystic fibrosis and its impact on the quality of life, and to examine whether demographic and clinical factors and negative emotional states are predictors of insomnia in these patients. The study was conducted among 95 cystic fibrosis patients aged 14-25 years. The study used a personal questionnaire survey, the Athens Insomnia Scale, the Cystic Fibrosis Quality of Life Questionnaire, the Hospital Anxiety and Depression Scale, and the Numeric Rating Scale. Insomnia was diagnosed in 38% of cystic fibrosis patients. In patients with insomnia, the level of anxiety (Me: 10 vs. 4; P=0.000) and depression (Me: 6.5 vs. 2; P=0.000) was significantly higher than in the good sleep quality group. The risk of insomnia increases as anxiety (OR: 4.31; 95% CI: 2.20 to 8.41) and depressive symptoms exacerbate (OR: 4.98; 95% CI: 1.84 to 13.43). Insomnia significantly worsens the quality of life in cystic fibrosis patients (ß =-0.5, P=0.000). Insomnia affects a large percentage of cystic fibrosis patients, and anxiety and depression are factors that increase the risk of insomnia. Insomnia decreases the quality of life in cystic fibrosis patients.

    Individuals with cystic fibrosis are at increased risk of colorectal cancer (CRC) compared with the general population, and risk is higher among those who received an organ transplant. We performed a cost-effectiveness analysis to determine optimal CRC screening strategies for patients with cystic fibrosis. We adjusted the existing Microsimulation Screening Analysis-Colon model to reflect increased CRC risk and lower life expectancy in patients with cystic fibrosis. Modeling was performed separately for individuals who never received an organ transplant and patients who had received an organ transplant. We modeled 76 colonoscopy screening strategies that varied the age range and screening interval. The optimal screening strategy was determined based on a willingness to pay threshold of $100,000 per life-year gained. Sensitivity and supplementary analyses were performed, including fecal immunochemical test (FIT) as an alternative test, earlier ages of transplantation, and increased rates of colonoscopy complications, to assess if optimal screening strategies would change. Colonoscopy every 5 years, starting at an age of 40 years, was the optimal colonoscopy strategy for patients with cystic fibrosis who never received an organ transplant; this strategy prevented 79% of deaths from CRC. Among patients with cystic fibrosis who had received an organ transplant, optimal colonoscopy screening should start at an age of 30 or 35 years, depending on the patient's age at time of transplantation. Annual FIT screening was predicted to be cost-effective for patients with cystic fibrosis. However, the level of accuracy of the FIT in this population is not clear. Using a Microsimulation Screening Analysis-Colon model, we found screening of patients with cystic fibrosis for CRC to be cost effective. Because of the higher risk of CRC in these patients, screening should start at an earlier age with a shorter screening interval. The findings of this study (especially those on FIT

    Purpose: To evaluate the ARFI ultrasound imaging with Virtual Touch tissue quantification in studying pancreatic cystic lesions, compared with phantom fluid models. Materials and methods: Different phantom fluids at different viscosity or density (water, iodinate contrast agent, and oil) were evaluated by two independent operators. From September to December 2008, 23 pancreatic cystic lesions were prospectively studied. All lesions were pathologically confirmed. Results: Non-numerical values on water and numerical values on other phantoms were obtained. Inter-observer evaluation revealed a perfect correlation (rs = 1.00; p < 0.0001) between all measurements achieved by both operators per each balloon and fluid. Among the pancreatic cystic lesions, 14 mucinous cystadenomas, 4 pseudocysts, 3 intraductal papillary-mucinous neoplasms and 2 serous cystadenomas were studied. The values obtained ranged from XXXX/0-4,85 m/s in mucinous cystadenomas, from XXXX/0-3,11 m/s in pseudocysts, from XXXX/0-4,57 m/s in intraductal papillary-mucinous neoplasms. In serous cystadenomas all values measured were XXXX/0 m/s. Diagnostic accuracy in benign and non-benign differentiation of pancreatic cystic lesions was 78%. Conclusions: Virtual Touch tissue quantification can be applied in the analysis of fluids and is potentially able to differentiate more complex (mucinous) from simple (serous) content in studying pancreatic cystic lesions.

    With increasing life expectancy, more women with cystic fibrosis and diabetes mellitus become pregnant. We investigated how pre-gestational diabetes (cystic fibrosis-related diabetes) influenced pregnancy outcome and the clinical status of these women. We analyzed all pregnancies reported to the French cystic fibrosis registry between 2001 and 2012, and compared forced expiratory volume (FEV 1 ) and body mass index before and after pregnancy in women with and without pre-gestational diabetes having a first delivery. A total 249 women delivered 314 infants. Among these, 189 women had a first delivery and 29 of these had pre-gestational diabetes. There was a trend towards a higher rate of assisted conception among diabetic women (53.8%) than non-diabetic women (34.5%, p = 0.06), and the rate of cesarean section was significantly higher in diabetic women (48% vs. 21.4%, p = 0.005). The rate of preterm birth and mean infant birthweight did not differ significantly between diabetic and non-diabetic women. Forced expiratory volume before pregnancy was significantly lower in the diabetic group. The decline in forced expiratory volume and body mass index following pregnancy did not differ between the women with and those without pre-gestational diabetes. Pre-gestational diabetes in women with cystic fibrosis is associated with a higher rate of cesarean section but does not seem to have a clinically significant impact on fetal growth or preterm delivery. The changes in maternal pulmonary and nutritional status following pregnancy in women with cystic fibrosis were not influenced by pre-gestational diabetes. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Conclusion: Ovarian cysts in young women who are associated with elevated levels of tumor markers and ascites require careful evaluation. Management of ovarian cysts depends on patient's age, size of the cyst, and its histopathological nature. Conservative surgery such as ovarian cystectomy or salpingo-oophorectomy is adequate in mucinous tumors of ovary. Multiple frozen sections are very important to know the malignant variation of this tumor and helps accurate patient management. Surgical expertise is required to prevent complications in huge tumors has distorted the anatomy, so gynecologic oncologist plays a prominent role in management. In this case, beside of the huge tumor and massive ascites uterine and ovaries were preserved by gynecologist oncologist and patient is well up to now.

Normal growth and development should be achieved in cystic fibrosis, and nutritional counseling is paramount at all ages. Prevention and early detection of growth failure is the key to successful nutritional intervention. The advance in nutritional management is certainly one factor that has contributed to the improved survival in recent decades. This review outlines the major nutritional parameters in the management of the patient with cystic fibrosis, including recent advances in pancreatic enzyme replacement therapy and fat-soluble vitamin therapy. There are sections on complicated clinical situations which directly affect nutrition, for example, before and after lung transplantation, cystic fibrosis-related diabetes, and bone health.Keywords: cystic fibrosis, nutrition, fat-soluble vitamins, pancreatic enzymes

    Respiratory distress and progressive lung destruction in cystic fibrosis can be attributed to bacterial persistence and the accumulation of viscous purulent secretions in the airways. More than 30 yr ago it was suggested that the large amounts of DNA in purulent secretions contribute to its viscosity and that bovine pancreatic DNase I could reduce the viscosity. To evaluate the potential clinical utility of recombinant human DNase I (rhDNase) in the treatment of cystic fibrosis, we have cloned, sequenced, and expressed rhDNase. Catalytic amounts of rhDNase greatly reduce the viscosity of purulent cystic fibrosis sputum, transforming it within minutes from a nonflowing viscous gel to a flowing liquid. The reduction in viscosity is associated with a decrease in size of DNA in the sputum. Inhalation of a rhDNase aerosol may be a simple direct approach that will help individuals with cystic fibrosis and other patients with pneumonia or bronchitis to clear their airways of purulent secretions.

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

    Intracerebral abscess is an uncommon complication of severe cystic fibrosis lung disease. The present report describes a case of fatal multiple intracerebral abscesses in a patient with a severely bronchiectatic, nonfunctioning right lung and chronic low-grade infection. The patient was previously turned down for pneumonectomy. Intracerebral abscess in cystic fibrosis and the potential role of pneumonectomy in the present patient are discussed.

    Although radiation therapy plays an important role in the management of children with brain tumors, radiation-induced brain damage sometimes occurs after radiation therapy. In some pediatric patients who had undergone cranial radiation therapy, we noticed cystic changes in the brain on follow-up MRI. The purpose of this study was to determine the frequency, latency, relationship with patient age, radiation dose, and serial change in the cystic changes in children after cranial irradiation. We retrospectively studied MRI in 33 children who had undergone cranial irradiation for their primary brain tumors. Postirradiation cystic change in the brain on follow-up MRI was defined as a well-demarcated, oval-shaped, CSF-like signal intensity area, and no contrast enhancement. Of the 33 patients, 6 (18.2%) had one or more cystic lesions. The latency of the cystic changes ranged from 1.5 to 7 years (mean 2.6 years). Cystic changes were found in the subcortical, periventricular and other deep white matter and the basal ganglia. The size of the lesions ranged from 1 to 10 mm at their first appearance; eight cystic lesions increased in size. None the cystic lesions reduced in size or resolved with time and none required intervention. All patients with cystic changes had received irradiation when they were 6 years of age or younger. The cystic changes occurred within the radiation field in patients treated with a radiation dose of 36 Gy or more. Asymptomatic brain parenchymal cystic changes appear to occur in children who have undergone cranial irradiation at 6 years of age or younger. (orig.)

    A pseudoaneurysm of the cystic artery is a rare complication of cholecystitis, and is manifested by hemobilia or hematemesis. An early diagnosis is required for the successful treatment by cholecystectomy and ligation of the cystic artery. Herein, we report a case of a pseudoaneurysm of the cystic artery diagnosed by color Doppler ultrasonography and CT, and successfully treated by transcatheter arterial embolization with N-butyl cyanoacrylate in a high-risk surgical patient.

    The incidental finding of pancreatic cysts is becoming more common because of the increased use of cross-sectional imaging. As a result, the perspective from historical series of symptomatic patients is not always applicable to the current cohort of patients with cystic lesions in their pancreas. In this review, the characteristic radiological features that aid diagnosis are highlighted, and the complementary role of different imaging methods and the appropriate use of tissue sampling are identified. Based on the literature regarding the diagnostic role of imaging in characterizing cystic pancreatic lesions, it is possible to recommend a practical imaging algorithm for the diagnosis of cystic pancreatic lesions

    Intestinal permeability was investigated in 14 children with cystic fibrosis making use of [ 51 Cr]EDTA as probe molecule. Ten normal young adults and 11 children served as controls. After oral administration of [ 51 Cr]EDTA, 24 h urine was collected. Urinary radioactivity was calculated and results expressed as percentage of oral dose excreted in 24 h urine. Mean and SEM were as follows: 2.51 +/- 0.21, 2.35 +/- 0.24, and 13.19 +/- 1.72 for control children, normal adults, and cystic fibrosis patients, respectively. The permeability differences between cystic fibrosis patients and either control children or control adults are significant (p less than 0.001)

    Non-tuberculous mycobacteria (NTM) are ubiquitous environmental organisms that can cause chronic pulmonary infection, particularly in individuals with pre-existing inflammatory lung disease such as cystic fibrosis (CF). Pulmonary disease caused by NTM has emerged as a major threat to the health of individuals with CF but remains difficult to diagnose and problematic to treat. In response to this challenge, the US Cystic Fibrosis Foundation (CFF) and the European Cystic Fibrosis Society (ECFS) convened an expert panel of specialists to develop consensus recommendations for the screening, investigation, diagnosis and management of NTM pulmonary disease in individuals with CF. Nineteen experts were invited to participate in the recommendation development process. Population, Intervention, Comparison, Outcome (PICO) methodology and systematic literature reviews were employed to inform draft recommendations. An anonymous voting process was used by the committee to reach consensus. All committee members were asked to rate each statement on a scale of: 0, completely disagree, to 9, completely agree; with 80% or more of scores between 7 and 9 being considered 'good' agreement. Additionally, the committee solicited feedback from the CF communities in the USA and Europe and considered the feedback in the development of the final recommendation statements. Three rounds of voting were conducted to achieve 80% consensus for each recommendation statement. Through this process, we have generated a series of pragmatic, evidence-based recommendations for the screening, investigation, diagnosis and treatment of NTM infection in individuals with CF as an initial step in optimising management for this challenging condition.
