  1. Mature Cystic Renal Teratoma

    International Nuclear Information System (INIS)

    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

    Abstract Teratomas are neoplasms that arise from pluripotent cells and can differentiate along one or more embryonic germ lines. Renal teratoma is an exceedingly rare condition. Teratomas commonly arise in the gonads, sacrococcygeal region, pineal gland, and retroperitoneum. They present mainly as an abdominal mass with few other symptoms. Majority of the tumors are benign, situated on the left side and para renal, occasional lesions are bilateral. If diagnosed early, they are amenable to cur...

    Primary upper abdominal teratomas are extremely rare tumours, most commonly arising in infants. The radiological literature relating to them is sparse. Surgical resection is difficult due to distortion of the vascular anatomy. To reassess the value of preoperative imaging with specific reference to the presence/absence of typical features of teratoma, anatomical location and adjacent vascular anatomy. The histopathology database was used to identify infants with upper abdominal teratoma. Pathological, surgical and radiological data were reviewed. The search of the database identified 12 infants (10 girls, 2 boys) with an abdominal/retroperitoneal teratoma during the period 1993 to 2006. All teratomas were benign. In the majority of infants, typical radiological features of teratoma were demonstrated (fat, calcium). Identification of the major abdominal vessels on CT scan (most commonly the inferior vena cava) was not possible in all infants. Distortion (and commonly encasement) of the adjacent major abdominal vessels was usually evident. Upper abdominal teratomas in infants have typical radiological features. Preoperative delineation of the major vascular anatomy is often imprecise. Significant distortion of vascular anatomy was present in all infants and awareness of this feature impacts on surgical planning. (orig.)

    Retroperitoneum is a relatively uncommon site for pediatric teratomas. Rarely, such tumors can have an intraspinal extension and few cases of retroperitoneal teratomas associated with spinal dysraphism have been reported. Teratomas consist of tissues arising from all three embryonic layers. However, mature renal tissues in the form of glomeruli and tubules are sparingly found in teratomas. A 15-day-old female presented with spina bifida occulta and on evaluation a cystic presacral mass was de...

  7. Primary retroperitoneal teratoma and crossed fused renal ectopia with turner's syndrome -a case report-

    International Nuclear Information System (INIS)

    In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type). The clinical, pathological and radiographical findings are reviewed

    A 74-year-old hypertensive woman presented with abdominal discomfort and a pulsatile abdominal mass. Anterior abdominal angiography during cardiac blood pool, and renal scintigraphic imaging demonstrated a large abdominal aortic aneurysm. 1, 2 Before endovascular repair with an aortoiliac endograft, the abdominal aneurysm measured 7.5 x 7.0 cm on abdominal computed tomography. This study demonstrates that a suspected abdominal aortic aneurysm can be confirmed using the addition of anterior abdominal imaging with normal posterior imaging at the time of renal scintigraphy.

    We report a case of intrarenal teratoma in a 6-year-old boy. Two years before his operation, multicystic masses had been found in the left side of his abdomen. In the operation, three main cystic masses were located in the upper and lower poles of the left kidney, which were removed in pieces. Histologically, the cyst wall was lined mainly with keratinizing squamous epithelium with hair follicles, shafts and sebaceous glands. The adjacent renal parenchyma showed atrophy, with partially dysplastic and angiomyolipoma-like lesions. Based on these findings, the lesion was diagnosed as mature cystic teratoma of dermoid cyst type. Extragonadal teratoma occurs predominantly along the median line of the body. Intrarenal teratoma is extremely rare; however, it should be distinguished from teratoid Wilms' tumor and other renal cystic lesions. PMID:11472570

    Full Text Available Amongst the varied, diverse causes of intraabdominal masses in infancy and early childhood, gastric teratomas (GTs account for a very small proportion. A worldwide literature search reveals only around one hundred cases of GT and also supports the fact that its preoperative diagnosis remains elusive. Here we report the case of a two-month-old male who presented to the pediatric surgery outpatient department of Kasturba Medical College and Hospital, Karnataka, India, with progressive distension of abdomen since birth. Clinically, a large firm, non-mobile and non-tender mass involving all four quadrants of the abdomen was seen. Ultrasound revealed a large solid-cystic mass with internal septations extending from the epigastrium up to the pelvis. Computed tomography revealed a large intraperitoneal fat containing solid-cystic mass lesion showing curvilinear and chunky areas of calcification, with the mass focally indenting the posterior gastric wall and showing focal polypoidal intragastric extension. Exploratory laparotomy revealed a large cystic tumor with a solid component, arising from lesser curvature of the stomach, showing focal intraluminal extension across the posterior gastric wall, and occupying the whole lesser sac and abdominal cavity. The tumor was excised in toto along with the body of the stomach. Histopathological examination showed mature tissue derived from all three germ cell layers and confirmed the diagnosis of mature gastric teratoma. The patient was disease free at one-year follow-up.

    Parasitic ovarian dermoid cysts are very rare. We report a rare case of bilateral ovarian dermoid cysts with parasitic teratoma at the hepato renal space measuring 11x11x6 cm while the other was twisted measuring 10x6x5 cm.Right ovary and tube were absent. The mass found at the hepato renal space was surrounded by and adherent to the omentum with viable tubal fimbria like structure at upper surface. Histopathologically both masses were confirmed as mature ovarian teratoma. The etiology of parasitic teratoma would be due to torsion followed by autoamputation and reimplantation of the right ovarian dermoid cyst. PMID:26744205

  12. Late renal function following whole abdominal irradiation

    International Nuclear Information System (INIS)

    Sixty patients treated with whole abdominal radiotherapy who had remained disease-free since completion of treatment participated in a study to assess the late clinical and biochemical effects of bilateral renal irradiation. Minimum follow-up was 5 years with a maximum of 20 years and a median of 9 years. Fifty-two patients in the study group were treated for primary ovarian cancer. Seven had non-Hodgkins lymphoma arising in the gastrointestinal tract and one patient had a carcinoid tumour arising in small bowel. None of the patients received chemotherapy. Abdominal radiation was given using an open beam technique to a mean dose of 22.92 Gy (range 6.68-27.54 Gy) in 1.02 to 1.25 Gy fractions treated once daily. Posterior kidney shields were used in order to limit the renal dose to <20 Gy. Mean radiation dose to both kidneys (retrospectively calculated) was 19.28 Gy (range 6.68-22.99 Gy). Patients ranged in age from 32-81 years with a median of 61 years. No patient had clinical evidence of renal impairment. Nine patients were hypertensive prior to radiotherapy and a further five patients became hypertensive after treatment. Serum creatinine values ranged from 44-123 μmol/l, with a mean of 87 μmol/l. Creatinine clearance ranged from 0.61-2.38 ml/s (mean 1.28 ml/s). Tubular function tests revealed one borderline high 24-h protein excretion and normal 24-h phosphorous and uric acid. Using a multiple linear regression analysis with creatinine clearance as the endpoint, age was the only significant variable (P < 0.00001) and renal dose and interval from treatment were not independently significant. There was no evidence of late renal toxicity more than 5 years after whole abdominal radiotherapy delivered with this technique and dose/fractionation schedule, and using the clinical and biochemical endpoints assessed in this study

    Full Text Available Introduction. Kidney anomalies present a challenge even for the most experienced vascular surgeon in the reconstruction of the aortoilliac segment. The most significant anomalies described in the surgery of the aortoilliac segment are a horse-shoe and ectopic kidney. Objective. The aim of this retrospective study was to analyze experience on 40 patients with renal anomalies, who underwent surgery of the aortoilliac segment and to determine attitudes on conventional surgical treatment. Methods. In the period from 1992 to 2009, at the Clinic for Vascular Surgery of the Clinical Centre of Belgrade we operated on 40 patients with renal anomalies and aortic disease (aneurysmatic and obstructive. The retrospective analysis involved standard epidemiological data of each patient (gender, age, risk factors for atherosclerosis, type of anomaly, type of aortic disease, presurgical parameter values of renal function, type of surgical approach (laparatomy or retroperitoneal approach, classification of the renal isthmus, reimplantation of renal arteries and perioperative morbidity and mortality. Results. Twenty patients were males In 30 (70% patients we diagnosed a horse-shoe kidney and in 10 (30% ectopic kidney. In the cases of ruptured aneurysm of the abdominal aorta the diagnosis was made by ultrasound findings. Pre-surgically, renal anomalies were confirmed in all patients, except in those with a ruptured aneurysm who underwent urgent surgery. In all patients we applied medial laparatomy, except in those with a thoracoabdominal aneurysm type IV, when the retroperitonal approach was necessary. On average the patients were under follow-up for 6.2 years (from 6 months to 17 years. Conclusion. Under our conditions, the so-called double clamp technique with the preservation of the kidney gave best results in the patients with renal anomalies and aortic disease.

    We present a case of a teratoma with somatic type malignancy (TSM) in the form of papillary renal cell carcinoma (pRCC) within supraclavicular and retroperitoneal lymph node metastases of a testicular pure teratoma. Resection of both masses revealed a teratoma without any other germ cell tumor component. A papillary carcinoma component was also detected intermingled with the teratomatous elements. The carcinoma cells displayed eosinophilic cytoplasm and prominent nucleoli. Groups of foamy histiocytes in the fibrovascular cores was a striking finding that brought pRCC to mind. Immunoreactivity for CK7, PAX8, AMACR, CD10, napsin, and vimentin along with morphologic findings confirmed renal cell differentiation. No radiological evidence of a primary renal cell carcinoma was found in the kidney. Consequently, pRCC arising in a teratoma was diagnosed. TSM is described as teratoma with a malignant component that is typically encountered in other organs and tissues. TSM in the form of pRCC is an extremely rare entity. Our case is the second example of a testicular germ cell tumor metastasis with a somatic malignancy in the form of pRCC. In conclusion, carcinomas of renal cell differentiation should be kept in mind as a rare form of TSM, especially in metastatic germ cell tumors. PMID:26936856

    Retroperitonal teratomas are rare. We report on a case of a retroperitoneal secondary localisation of a gonadal teratoma in a patient who had developed primary testicular teratoma 12 years previously. The retroperitoneal mass was detected with an abdominal CT requested for the management of a non-specific abdominal pain. CT and MRI examinations showed cystic retroperitoneal masses combined with calcifications and peripheral enhancement. Review of the literature is presented, including the common differential diagnoses to be considered. PMID:22338389

    We describe a case of a giant intra-abdominal mature cystic teratoma in a 36-year-old man, which comprised typical features of differentiated teratoma/dermoid cyst but which contained a macroscopic rudimentary penis, with vasoformative erectile tissue-like structures consistent with corpora cavernosa, as well as scrotal-type skin and prostatic tissue. The genitourinary structures were well formed both grossly and microscopically and sharply demarcated from the rest of the neoplasm, which comprised typical differentiated teratoma, without any other macroscopic foci of organoid differentiation or of other histologic differentiation. The plasticity of the cells of differentiated teratoma, which enables it to undergo multidirectional differentiation, is well recognized, but the factors determining this distinct path of differentiation remain to be established.

  4. Renal Atrophy Secondary to Chemoradiotherapy of Abdominal Malignancies

    International Nuclear Information System (INIS)

    Purpose: To identify factors predictive of renal atrophy after chemoradiotherapy of gastrointestinal malignancies. Methods and Materials: Patients who received chemotherapy and abdominal radiotherapy (RT) between 2002 and 2008 were identified for this study evaluating change in kidney size and function after RT. Imaging and biochemical data were obtained before and after RT in 6-month intervals. Kidney size was defined by craniocaudal measurement on CT images. The primarily irradiated kidney (PK) was defined as the kidney that received the greater mean kidney dose. Receiver operating characteristic (ROC) curves were generated to predict risk for renal atrophy. Results: Of 130 patients, median age was 64 years, and 51.5% were male. Most primary disease sites were pancreas and periampullary tumors (77.7%). Median follow-up was 9.4 months. Creatinine clearance declined 20.89%, and size of the PK decreased 4.67% 1 year after completion of chemoradiation. Compensatory hypertrophy of the non-PK was not seen. Percentage volumes of the PK receiving ≥10 Gy (V10), 15 Gy (V15), and 20 Gy (V20) were significantly associated with renal atrophy 1 year after RT (p = 0.0030, 0.0029, and 0.0028, respectively). Areas under the ROC curves for V10, V15, and V20 to predict >5% decrease in PK size were 0.760, 0.760, and 0.762, respectively. Conclusions: Significant detriments in PK size and renal function were seen after abdominal RT. The V10, V15, and V20 were predictive of risk for PK atrophy 1 year after RT. Analyses suggest the association of lower-dose renal irradiation with subsequent development of renal atrophy.

    We report a case in which an immature teratoma developed following three previous resections for mature cystic teratomas. The patient was a 26-year-old nulliparous woman with a regular menstrual cycle. Twelve years earlier, she had consulted a pediatrician for complaints of lower abdominal pain. Bilateral cystic teratomas were suspected and she underwent a left salpingo-oophorectomy and a right cystectomy laparoscopically, and bilateral mature cystic teratomas were diagnosed histologically. She underwent a right cystectomy twice afterwards and mature cystic teratomas were diagnosed. Three years after the third surgery, a regular checkup performed annually for ovarian cyst recurrence revealed a 9.3 cm ovarian cyst by ultrasonography without marker elevation or complaint of symptoms. Magnetic resonance imaging (MRI) showed a 10 cm multilocular cyst, including a part with heterogeneous medium and high-signal intensity on T2-weighted images, which revealed enhancement on dynamic contrast-enhanced MRI unlike the previous images. Ovarian tumors, including immature teratomas and malignancy, were considered. She had a strong wish to undergo laparoscopic surgery. She was diagnosed with an immature teratoma, grade 1 of the right ovary. Although the frequency of recurrence of immature teratomas after resection of mature cystic teratomas is very low, regular checkups are necessary because there may be no associated symptoms.

    Vascular disorders affecting the kidneys are either acquired or congenital. Included in this category are common multiplicity of renal arteries, the rare arteriovenous malformation, stresses due to fibromuscular disease or atherosclerosis including abdominal aortic aneurysms, arterial thrombosis, venous thrombosis, and infarction. In contrast to the group of cystic and neoplastic kidneys where scintigraphic or pathologic are not diagnostic, scintigraphic or pathologic anatomy in vascular disease is often diagnostic by nuclear medicine techniques. The authors present an interesting case of evaluation of acute renal failure in a patient abdominal aortic aneurysmectomy and axillo-bifemoral bypass graft.

Discuss antenatal management of sacrococcygeal teratoma?.......1. Incidence is said to vary from 1 per 50,000 live births to 1 in 35,000 live births. But a population based study from Newcastle upon Tyne, UK has found the incidence to be 1 in 27,000 live births [1]. 2. Various interdependent clinical and epidemiologic variables such as the age at diagnosis, sex, tumor site, histology which all correlate to different cytogenetic and molecular biologic aberrations; are considered to modify biologic behaviour of teratomas. Size of a sacrococcygeal teratoma (average 8 cm, range 1 to 30 cm does not predict its biological behaviour. Histological grading of SCT does not seem to correlate with prognosis [2]. 3.

    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    Full Text Available The purpose of this article was to report our first experience in surgical treatment of aortic aneurism rupture in patient of 55 years old with renal transplant. Aortic aneurism rupture always associated with high mortality, and urgent operative procedure is also rather complicative and has also in bad anatomical conditions. The expectation of good collateral circulation for renal transplant, quick cross-clamp time and easy graft replacement may not always be the case. We believe that trans- planted kidney should be protected when ever feasible, especially in urgent procedure.

    Full Text Available Introduction. Mature teratomas (benign cystic teratomas or dermoid cysts are among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. Teratoma in the intraperitoneal cavity is uncommon and atypical, and it is even more uncommon in adulthood. Case Outline. An 82-year-old female was admitted to our department with clinical signs of abdominal tumour. The ultrasound scan and preoperative laboratory tests were done. Explorative laparotomy revealed tumour with torsion on its pedicle at the greater omentum. After removal of the mass and the incision a tooth and hair were found, characteristics of teratoma. Conclusion. The excision was very effective and also definitive treatment for this case. The patient recovered well and was discharged 3 days later. The patient probably carried the tumour all her life asymptomatically until admission.

    Retroperitoneal teratoma is a congenital retroperitoneal tumor containing three germ layers, with no anatomical connections to reproperitoneal organs. The ultrasonographic findings of 9 pediatric retroperitoneal teratomas were analysed. The most characteristic ultrasonographic pattern was coplex echogenic tumor showing cystic mass containing variable pattern of solid echoes due to calcification, fatty component or other solid component. Calcifications showed high spotty echoes with posterior shadowing and fatty component showed very refractile echoes protruding into the cystic portion. In addition to plain abdominal radiography, the ultrasonographic characteristics of retroperitoneal teratoma is expected to improve diagnostic accuracy

    An epignathus is an extremely rare form of oropharyngeal teratoma that arises from the oral cavity, most commonly from the palate and is associated with a high mortality, secondary to airway obstruction in the neonatal period. We present a case of epignathus, diagnosed on antenatal ultrasound as teratoma. It was associated with polyhydramnios. The mother had presented with preterm labour at 27 weeks of gestation. Astillborn baby girl with a large epignathus was expelled spontaneously 2 hours after admission. Accurate prenatal diagnosis of the condition can be done by prenatal ultrasound including colour Doppler ultrasound, three dimensional ultrasound and MRI. The patient can be managed by EXIT (ex uterointrapartum treatment) procedure immediately after birth. Alternatively, the airway can be secured initially and a more complicated surgery can be undertaken once the patient is stable. Foetal surgery is another theoretical possibility. PMID:27225155

    2013-05-01

    Non-contrast-enhanced MR angiography is a promising alternative to the established contrast-enhanced approach as it reduces patient discomfort and examination costs and avoids the risk of nephrogenic systemic fibrosis. Inflow-sensitive slab-selective inversion recovery imaging has been used with great promise, particularly for abdominal applications, but has limited craniocaudal coverage due to inflow time constraints. In this work, a new non-contrast-enhanced MR angiography method using velocity-selective inversion preparation is developed and applied to renal and abdominal angiography. Based on the excitation k-space formalism and Shinnar-Le-Roux transform, a velocity-selective excitation pulse is designed that inverts stationary tissues and venous blood while preserving inferiorly flowing arterial blood. As the magnetization of the arterial blood in the abdominal aorta and iliac arteries is well preserved during the magnetization preparation, artery visualization over a large abdominal field of view is achievable with an inversion delay time that is chosen for optimal background suppression. Healthy volunteer tests demonstrate that the proposed method significantly increases the extent of visible arteries compared with the slab-selective approach, covering renal arteries through iliac arteries over a craniocaudal field of view of 340 mm.

Like Athena of Greek mythology, she distills wisdom from published literature.Athena is fascinated by the tailbone (coccyx for more than one reason: it is named poetically after the beak of a cuckoo; it is the key Darwinian link between the tail of primates and the tailless Homo sapiens; notwithstanding its tiny size it plays a vital role in anal continence by giving attachment to anal sphincters; and above all it harbors totipotent stem cells giving rise to a peculiar tumor - the Sacrococcygeal Teratoma (SCT. This tumor is peculiar because it is almost always benign to start with and it turns malignant with passage of time. This emphasizes the importance of early surgery and the need to excise coccyx in SCT. Athena believes that studying the natural history of SCT may unravel the secrets of oncogenesis. ...

    Abstract An independent association between acute renal failure(ARF)and intra-abdominal hypertension(IAH)after liver transplantation has not been established previously.The aim of this retrospective study was to understand the role of IAH as an independent risk factor for ARF in the early postoperative period.This study involved 62 subjects who underwent liver transplantation.Intra-abdominal pressure (IAP)was measured in the first three days after surgery by using the urinary bladder technique.An IAP of at least 20 mmHg per day was defined as IAH.Clinical parameters between group IAH and group NO-IAH were compared in terms of the incidence of ARF,blood creatinine levels,blood urea nitrogen (BUN)levels,urine volume per hour and glomerular filtration gradient(GFG).Hemodynamic variations were recorded in the first three postoperative days between group ARF and group NO-ARF.The perioperative suspected risk factors of ARF were determined for statistical evaluation using correlation coefficients and logistic regression analysiIn group IAH.45.8%patients developed ARF as against 7.9in group NO-IAH;GFG was significantly lower at 0-72 h after surgery;and blood creatinine levels,BUN levels,urine volume per hour were significantly different at 24-72 h after surgery compared with group NO-IAH.The patients with ARF were not significantly difierent from those without ARF in terms of central venous pressure,pulmonary artely pressure and mean arterial pressure(MAP) in the first three postoperative days despite a significant increase in heart rate at 24-72h after operation.Postoperative IAH,intraoperative MAP and intraoperative blood transfusion volume of more than 15 U were found to be independent risk factors for ARF.IAH impaired renal function and was an independent risk factor for ARF after liver transplantation.Routine measurement should be taken to monitor IAP every eight hours postoperatively.

    Full Text Available We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

  6. Sacrococcygeal teratoma showed a large cyst on CT scan

    International Nuclear Information System (INIS)

    A newborn case with a sacrococcygeal teratoma is reported. A female baby had been noted at birth to have a small hairy pigmented skin lesion over her sacral region. She had shown acute obstructive ileus and bilateral hydronephrosis before long. A benign teratoma with a large cyst was demonstrated on ultra sound echogram and CT scan. The tumor was apparent externally but the predominant mass was intra-pelvic and extended into the retroperitoncal cavity of abdomen. Sacrococcygeal teratoma is uncommon but early diagnosis and surgery is necessary for aquiring good prognosis because it is almost benign. Abdominal CT scan is very worthy and required for diagnosis of the sacrococcygeal teratoma and the differential diagnosis of anterior myelomenigocele and congenital dermal sinus, etc. When a newborn baby is recognized a skin lesion over the sacral region, even though it is mild, CT scan will be necessary for the correct diagnosis, especially in female cases.

    Growing teratoma syndrome (GTS) is a rare complication of malignant ovarian germ cell tumors. A 52-year old woman was admitted to our Gynecological Oncology Department with metastatic multiple abdominal masses. Her initial gynecological history presented an immature teratoma of the ovary 3 years previously, and she underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic-paraaortic lymphadenectomy and omentectomy. She received three cycles of bleomycin, etoposide and cisplatin (BEP) regimen after surgery. Although the tumor markers were within normal limits, multiple metastatic lesions were detected in the 3rd month of follow-up. The patient was referred to our gynecological oncology department, optimal debulking including resection of the tumoral lesions localized on the liver, diaphragm, peritoneum, sigmoid colon, omentum and retroperitoneum was performed. Histopathology of all samples revealed mature teratoma. This syndrome should be remembered when a tumor is refractory to chemotherapy and growth of the tumor still continues after resection of the initial tumor.

    Teratomas are rare and complex tumors with components from more than one of the three germ cell layers. Teratomas range from benign, well-differentiated (mature) cystic lesions to those that are solid and malignant (immature). The incidence of all teratomas is estimated at 1:10,000-1:20,000 newborns. Gastric teratomas represent only 1-2% of all teratomas.

    Full Text Available Introduction. Teratomas are tumours derived from pluripotent germ cells. They appear most frequently on ovaries. However, other locations are also possible: testicles, retroperitoneum, stomach, neck, and bottom of the mouth cavity. It is not very common to find teratomas in two different body cavities. Case report. A 51-year-old patient visited her doctor complaining of an intensive pain which suddenly appeared in her low back. The computed tomography scan of the abdomen was performed, which revealed cystic formation, 12.5 x 18 cm in size, with remarkable capsule visualization. It had paraaortic, subdiaphragmatic, retropancreatic and suprarenal left localisation with signs of compression and pancreatic dislocation. The cystic formation had a septated appearance filled with clear fluid in all its parts except at the bottom, where it was dense. The intra-operative finding was left retroperitoneal mass placed above the left kidney, dislocating surrounding structures and their infiltration could not be excluded for sure. A tumour mass passed through the diaphragmatic hiatus and continued in the left thoracic space. The cyst was only drained and the fenestration was performed. Three months later, the second operation was performed-splenectomy, left suprarenaladenectomy, left nephrectomy, aortic deliberalisation, the left diaphragmatic crus was opened and tumour mass was completely removed from the thoracic space. The histological examination showed mature teratoma with morphological characterisations of the skin, so the definite diagnosis was dermoid cyst. Conclusion. The patient presented with thoracoabdominal teratoma. Although without malignant transformation, the teratoma required splenectomy, supraadrenalectomy and nefrectomy due to its position and size.

    Proximal infrarenal neck anatomy is a crucial factor in determining outcome of abdominal aortic aneurysm (AAA) repair. Unfavorable or demanding infrarenal neck anatomy significantly increases the complexity of both standard endovascular and open repair resulting in increased rates of morbidity and mortality. While technological improvements and expanding institutional experience have resulted in an increased proportion of patients with an AAA with unfavorable infrarenal neck treated by (fenestrated) endovascular techniques, open repair has also remained a valid technique. The purpose of this manuscript was to describe the wide array of endovascular and open techniques in use to treat patients with an AAA with a demanding infrarenal neck and discuss their results and indications.

To compare the diagnostic performance of CT and MRI for local staging of pediatric renal tumors. The study population was derived from the AREN03B2 study of the Children's Oncology Group. Baseline abdominal imaging performed with both CT and MRI within 30 days of nephrectomy was available for retrospective review in 82 renal tumor cases. Each case was evaluated for capsular penetration, lymph node metastasis, tumor thrombus, preoperative tumor rupture, and synchronous contralateral lesions. The surgical and pathological findings at central review were the reference standard. The sensitivity of CT and MRI for detecting capsular penetration was 68.6% and 62.9%, respectively (P = 0.73), while specificity was 86.5% and 83.8% (P = 1.0). The sensitivity of CT and MRI for detecting lymph node metastasis was 76.5% and 52.9% (P = 0.22), and specificity was 90.4% and 92.3% (P = 1.0). Synchronous contralateral lesions were identified by CT in 4/9 cases and by MRI in 7/9 cases. CT and MRI have similar diagnostic performance for detection of lymph node metastasis and capsular penetration. MR detected more contralateral synchronous lesions; however these were present in a very small number of cases. Either modality can be used for initial loco-regional staging of pediatric renal tumors. (orig.)

    Full Text Available Background: Benign cystic teratoma is the most common tumor of ovary. Though bilateralism is seen in 10-15% of the cases, bilateral and multiple benign cystic teratomas are rare and very few cases have been reported in the literature. Aim: We present a case of bilateral and multiple benign cystic teratomas with a broad ligament leiomyoma. Case findings: A 38 –year- old female presented with lower abdominal pain of 5 months duration. Ultrasonography of abdomen showed bilateral multiple adnexal cystic masses with multiple hyper-echoic solid components. Laparoscopy was done. There were bilateral tumors, two on right side and three on left side. Posterior surface of the uterus showed a fibroid. Ovarian cystectomy and myomectomy was done under general anesthesia with preservation of both ovaries. Report of bilateral and multiple benign cystic teratomas with broad ligament fibroid was given. Conclusion: When teratomas are multiple and bilateral, recurrence in the form of a dermoid cyst (3% or immature teratoma (2-2.6% in the residual ipsilateral ovary is most frequent. Because of the rarity and increased recurrence rate, we are presenting this case.

    Teratomas are the most common germ cell tumors among pediatric and female patients, which originates from germ cells layers and can be located everywhere in bodies. They are diagnosed by ultrasonography (US), which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological im-aging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was per-formed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gyneco-logical diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

    2005-11-01

    Full Text Available Abstract Background Teratomas are manifested with a great variety of clinical and radiological features, while sometimes they simply represent incidental findings. Case presentation A rare case of benign teratoma of the dermoid cyst type, in an adult 40-year-old female patient, is reported. The patient had presented recurrent pulmonary infections for the previous 2 months, persistent cough, and progressively aggravating dyspnea. A chest X-ray showed total atelectasis of the left lung, and the thoracic CT-scan revealed a huge mass, containing multiple elements of heterogeneous density, probably originating from the mediastinum, occupying the whole left hemithorax. The mass compressed the vital structures of the mediastinum, great vessels and airways, and a chest MRI was performed to accurately detect the anatomical relations. The patient underwent left thoracotomy and the tumor was totally resected. The size of the tumor was extremely large although no invasion to the vessels or to the airway had occurred. Adherence to the adjacent left pulmonary artery and left main bronchus was present, but without erosion or fistulization. The postoperative course was uneventful, while the histological examination confirmed a teratoma. Conclusion A teratoma is a non-homogeneous pathological entity, clinically, radiologically or histologically. It is predominantly diagnosed between the second and fourth decade and the incidence is equal for both sexes. Symptoms are absent in one half of the patients. The case reported is noteworthy as the tumor appeared with total atelectasis of the left lung, and symptoms started 2 months prior to diagnosis. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent.

    Teratomas are thought to arise from totipotent primordial germ cells (PGCs) Dehner (1983) which may miss their target destination Moore and Persaud (1984). Teratomas can occur anywhere from the brain to the coccygeal area but are usually in the midline close to the embryological position of the gonadal ridges Bale (1984), Nguyen and Laberge (2000). We report a case of a bipartite anterior extraperitoneal teratoma. This is an unusual position for a teratoma, but one which may support the “mis...

    Teratomas are tumors composed of tissues derived from more than one germ cell line. Pulmonary teratomas are rare and commonly involve the upper lobe of the left lung. Criteria for pulmonary origin are the exclusion of a gonadal or other extragonadal primary site and origin entirely within the lung. We report a case of a giant pulmonary teratoma in a 2-year-old male child and review the relevant literature.

    2003-04-01

    Background: Neonatal nasopharyngeal teratomas are extremely rare and there are few reports describing both CT and MRI features of these lesions. Objective: To describe the CT and MRI appearances of neonatal nasopharyngeal teratoma. Materials and methods: Three neonates with nasopharyngeal teratomas and severe respiratory distress were reviewed. Results: The nasopharyngeal mass resulted in severe respiratory compromise requiring urgent intervention. Characteristic mandibular and pterygoid plate abnormalities demonstrated by CT and MRI are described. Conclusions: Prenatal MRI enables the diagnosis, delineates tumour extent and allows planned delivery. CT and MRI play a key role in differentiating neonatal nasopharyngeal teratomas from other causes of a neonatal neck mass, thus optimising management. (orig.)

    Full Text Available Germ cell tumors are malignant (cancerous or nonmalignant (benign, noncancerous tumors that are comprised mostly of germ cells, the cells that develop in the embryo and become the cells that make up the reproductive system in male and female. Most ovarian tumors are of germ cell origin. A 5-year-old female child was taken to the Paediatrics department at Tawau General Hospital (TGH, Sabah, Malaysia on 10.4.2005 with gradual distension of abdomen which had been noticed by parents for the last 2 months. As bedside ultrasonography (USG showed mixed echogenic mass in the lower abdomen, CT scan of abdomen was requested for further delineation. CT scan of abdomen done on 18.4.2005 showed a very large (about 12 × 9 cm mixed density mass with homogenously enhancing well defined borders in the abdomen extending from the pelvic cavity to the upper abdomen causing significant pressure effect downwards towards urinary bladder and contrast material filled guts outwards and backwards mostly occupying the anterior part of abdominal cavity. The tumor was removed surgically and diagnosed as ovarian teratoma histopathologically.

  5. Cystic struma ovarii: a rare ovarian teratoma

    International Nuclear Information System (INIS)

    Struma ovarii is a unique variant of the monodermal teratomas of the ovary, which is entirely composed of thyroid tissue. It is a rare tumor which comprises 1-4% of all benign ovarian tumors. The age of presentation ranges between 6 to 74 years. It is a benign tumor and is usually unilateral. Clinical symptoms such as pelvic mass, abdominal pain and ascities occur in one third of patients, whereas rarely patients may present with pseudo-meig syndrome. Ultrasonography and computed tomography show a solid cystic mass. Histologically benign struma ovarii contain thyroid follicles of variable sizes filled with colloid. A 53 years old female presented with one month history of lower abdominal pain. The clinical and radiological findings suggested a left ovarian mass measuring 7 x 5 x 3 cm. An exploratory laparotomy was performed and the left ovarian mass was resected. The specimen was sent to AFIP for anatomical diagnosis. On gross examination, the specimen consisted of left ovary measuring 14 x 12 x 6.5 cm and weighing 527 grams. External surface of the ovary showed many multinodular areas with few cystic areas. Largest of the cyst measured 8 x 7 x 4 cm. On opening all the cysts contained yellowish watery fluid. Maximum thickness of the largest cyst wall was 0.5 cm. The solid area in the ovary measured 5 x 4 x 3 cm. On serial slicing the solid areas had whitish variegated appearance and areas of gritty hard consistency. No fallopian tube was found. Representative sections from different areas of the specimen were prepared. Histologically, the sections revealed effacement of the normal ovarian architecture by mature thyroid follicles containing colloid (Fig. 2). Some areas showed degenerated thyroid tissue with hyalinization and areas of calcification. More than 50% of the material examined contained thyroid tissue. No evidence of atypia was seen in the material examined. (author)

    Full Text Available Mature cystic teratoma compromise 20-30% of all ovarian tumours. They are mostly seen in patients between 20 and 40 years of age and are mostly asymptomatic. Malignancy incidence is high in postmenopausal group. Here, we report a case of mature cystic teratoma presenting unusually in a 65 year old postmenopausal woman with pain abdomen. A 65 year old postmenopausal woman presented with lower abdominal pain of 15 days duration. Upon examination, a mass of size 7 and times;8 cm felt on bimanual examination. CT showed the same cyst that has a focal enhancing mural nodule with fat density in it. Total abdominal hysterectomy with bilateral salpingo oopherectomy done. Histopathological examination confirmed mature cystic teratoma. Although mature cystic teratoma is rare after 40 years age, especially in postmenopausal women and are usually malignant in that age group, it can have an unusual age presentation at 65 years with benign nature as in our case.

    Full Text Available Blunt rupture of the renal pelvis is a exceedingly rare injury. Hematuria is absent in one-third of cases. Such injuries are usually caused by desacceleration forces. Despite improved imaging techniques, diagnosis of this injuries is frequently delayed. Diagnosis is suggested by the presence of massive medial extravasation of contrast material at excretory urography or computed tomography. Surgical treatment consists in pyeloplasty or pyeloraphy with stent placement (double J or nephrostomy.

    To evaluate the sonographic findings of fetal congenital intracranial teratoma. From 1994 to 2002, of the 11 fetuses which had been diagnosed with fetal intracranial tumors after second level fetal ultrasonography, the six that were confirmed after autopsy as congenital intracranial teratomas were included in our study. The sonographic findings, including size, homogeneity, echogenicity compared with surrounding normal brain tissues, cystic components, and tumor related calcification, were retrospectively evaluated. The incidence of fetal congenital intracranial teratoma out of all fetal intracranial tumors was 54.5% (6 of 11 cases) during the 8-year period. The mean mass size was 7.4 cm (3.0-15.0 cm). Two thirds of (4/6) of the teratoma cases showed high echogenicity compared with normal brain tissues, and two thirds (4/6) showed heterogeneous echogenicity. Four teratoma cases (67%) showed cysts in the mass with a mean size of 1.9cm. One third (2/6) showed calcifications within the tumor. Out of the six cases, two had oropharyngeal teratoma with extension into the intracranial portion (so called epignathus) and showed homogenous mass without any cysts or calcifications. The typical sonographic appearance of intracranial teratoma was a heterogeneous, hyperechoic mass with cysts. In the epignathus cases, the sonographic appearances differed somewhat from the others. An understanding of the sonographic findings of fetal intracranial teratoma will help in the timely counseling of the parents and in obstetric decision making

    Full Text Available Abstract Background Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. Case presentation We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eighteen month old Nigerian female who presented with a history of noisy breathing associated with recurrent rhinorrhea since birth. Physical examination revealed obstruction of the right nasal cavity by a pale fleshy mass. She underwent a total surgical excision and to date, after thirty one months follow-up, she is free from recurrence. Conclusion The prognosis for benign teratoma of the nasal septum is good following total surgical excision.

    Full Text Available This study considers a unilateral renal agenesia associated with agenesia of the epididymis body and tail and the vas deferens and non-palpable left testicle in a 20-month-year-old patient. During laparoscopic procedure, the testicle was positioned at approximately 5 cm above the inguinal ring. The size was appropriate for the age and the head of the epididymis was situated in its normal position. The decision was made to perform the first step of the Fowler-Stephens’ surgery and the patient presented a good evolution. The association of male duct system agenesia with unilateral renal agenesia in a patient with cryptorchidism diagnosed by laparoscopy is an extremely rare event, however generally in these cases the testicle is of normal size, presents unaltered hormonal function, and must be preserved.

    Teratomas are benign tumors that form after ectopic injection of embryonic stem (ES) cells into mice and contain derivatives of all primitive germ layers. To study the role of beta 1 integrin during teratoma formation, we compared teratomas induced by normal and beta1-null ES cells. Injection of...... normal ES cells gave rise to large teratomas. In contrast, beta 1-null ES cells either did not grow or formed small teratomas with an average weight of <5% of that of normal teratomas. Histological analysis of beta 1-null teratomas revealed the presence of various differentiated cells, however, a much...... lower number of host-derived stromal cells than in normal teratomas. Fibronectin, collagen I, and nidogen were expressed but, in contrast to normal teratomas, diffusely deposited in beta1-null teratomas. Basement membranes were present but with irregular shape and detached from the cell surface. Normal...

    Ultrasonography is a very useful diagnostic modality for the evaluation of clinically suspicious abdominal masses in infants and children, especially in assessing their existence, size, location, origin and internal consistency. Authors analyzed and present ultrasonographic findings of 92 pathologically and/or clinically proven pediatric abdominal masses that were studied and treated in Chonnam University Hospital during recent 4 years. The results were as follows: 1. The most common originating site was kidney (26 cases: 28.3%), followed by gastrointestinal tract (21 cases: 22.8%), genital organ (17 cases: 18.5%), non-renal retroperitoneum (13 cases: 18.5%), hepatobiliary tract (12 cases: 13.0%), and anterior abdominal wall (3 cases: 3.3%) in order to frequency. 2. The most common mass was hydronephrosis (18 cases: 19.6%). Neuroblastoma (7 cases: 7.6%), hepatoblatoma, ovarian teratoma, periappendiceal abscess and abdominal tuberculosis (6 cases: 6.5%, respectively), Wilms tumor (5 cases: 5.4%) were next in order of frequency. 3. The sex distribution is rather similar, that is, male 42 (45.7%) and female 50 (54.3%), but characteristically choledochal cyst (2 cases) and genital mass (17 cases) were found only in females. Considering age distribution, 78 cases (84.8%) were found within the range of one to 15 years of age. The rest, 14 cases (15.2%), were under the age of one year. 4. With ultrasonography, the diagnosis of hydronephrosis could be made easily in every case and we could evaluate its severity and level of obstruction with high accuracy. 5. All Wilms tumor were large, round or oval, sharply marinated and relatively homogeneous solid masses. 6. All neuroblastomas were irregular shaped, poorly defined, heterogeneous solid masses. Tumor calcification and extension across the midline were noted in 6 cases (85.7%) and 5 cases (71.4%), respectively. 7. All periappendiceal abscess had irregular thickened wall and posterior acoustic enhancement; 4 cases (66

    Mature cystic teratomas are benign neoplasms of germ cell tumors that occur most frequently in gonadal sites. The tumors usually contain 2 or 3 well-differentiated elements of endodermal, ectodermal, and mesodermal origin. Although relatively uncommon, teratomas can be composed of mature tissue originating from only 1 germ cell layer. This is known as a monodermal teratoma. Extragonadal teratomas, especially mesenteric teratomas, are extremely rare. Currently, only 21 cases of mesenteric tera...

    Full Text Available Background:Congenital germ cell tumors are uncommon. The most common site of teratoma is in the sacrococcygeal region. Teratoma arising from the head and neck comprises less than 10% of reported cases and of these, nasopharyngeal lesions are rare. Teratomas are generally benign, and have a well recognized clinical and histopathological entity. We present a case of nasopharyngeal teratoma (NPT associated with a wide cleft palate. Case Presentation:A 20 day old female neonate with a teratoma of the nasopharyngeal area, and wide cleft palate was referred to our center. The protruded mass which measured 6×4×3cm, was of soft consistency, blocked the airway, and prevented oral feeding. Preoperative evaluation and imaging was performed and mass was excised 2 days after admission. Pathology revealed a well-differentiated mature solid teratoma (hairy polyp. The patient had no complication in the post-operative period. Cleft palate was surgically repaired when 2 years old. She is now a six year old girl with normal development. Conclusion:Congenital nasopharyngeal teratomas are usually benign. Surgery is the treatment of choice, and should be undertaken on an urgent basis, especially in a patient who presents with signs and symptoms of airway obstruction.

    Full Text Available Teratoma is a tumor that derivatives from all three primitive germ layers and spinal intramedullary teratomas are very rare lesions. The primary treatment modality for these tumors is surgical resection, and total resection should be the aim. However, subtotal resection is a valid alternative to prevent traumatizing adjacent functional neural tissue. In this report, we presented a case of a 12-year-old male patient with spinal teratoma of the conus medullaris. We describe the presentation, evaluation, and treatment of this rare disease.

Here we report a case of malignant retroperitoneal teratoma (dermoid in a 15 year old girl who presented to our hospital - Acharya Vinoba Bhave Rural Hospital (AVBRH. She presented with a tender, large, irregular mass with variegated consistency in the entire left side of abdomen crossing midline. Ultrasound of abdomen suggested a complex intra-abdominal mass with septations and lobulations. It was not feasible to use other imaging modalities for evaluation due to poor socio-economic status and illiteracy. Patient underwent exploratory laparotomy with tumor resection along with left kidney and part of the descending colon which was densely adhered to tumor. Histopathological examination of tumor was suggestive of immature teratoma. Post operative recovery was uneventful and patient was discharged from the institution. Tissue adherence which can be observed in both benign and malignant form of teratomas, requires extended surgery for removal of adhered organ for the completeness of surgery and good prognosis.

  8. Diagnostic imaging of infantile abdominal cystic disease

    International Nuclear Information System (INIS)

    Thirty-seven patients with infantile abdominal cystic disorders were studied by ultrasound (US), computed tomography (CT), or magnetic resonance imaging (MRI). US studies are simple to conduct, and commonly show an echo-free mass, but tend to yield hyperechoic images when fat and blood are present in the cystic fluid. CT studies, which distinctly demonstrate water, fat, soft tissue density and calcification, are very helpful in the diagnosis of cystic tumor, especially cystic teratoma. MR imaging, which is capable of distinguishing the nature of the cystic fluid (e.g., serous, chylous, bloody, fatty, etc.), is useful in the diagnosis of lymphangioma, teratoma, and torsion of ovarian cystic tumor. Based on the results of the present study, US may be considered to be the modality of first choice in the examination of infantile abdominal cystic disorders, and MRI and/or CT should be employed additionally as necessary in that order.

    Teratomas, usually arising in the anterior mediastinum, are very uncommon in the posterior mediastinum. Embryologic development of anterior mediastinal teratoma is thought to be from thymic anlage which descends from the third bronchial cleft and pouch, while that of posterior mediastinal teratoma is thought to be from the remnant of notochord. CT findings of posterior mediastinal teratomas are not different from teratomas elsewhere, containing fat, calcification, soft tissue and thick walled cyst. Ultrasonographic findings are mixed echogenic mass containing cystic portion, highly reflective solid portion and area of acoustic shadowing.

    We reviewed the magnetic resonance imaging(MRI) of intracranial teratoma to defect the characteristic findings. Five patients with intercranial teratoma were evaluated with MRI from January 1988 to December 1990. Four male and one female patients with age ranging from 6 to 14 years were surgically confirmed. MRI was done with 2.0 T superconducting system(Spectro 20000, Goldstar, Seoul) and gadolinium enhancement was done in 4 patients. We retrospectively reviewed the clinical, operative, pathologic, and radiologic findings. Intracranial teratomas showed fatty component, calcification and cystic component filled with sebum or serous fluid. Peripheral rim enhancement was seen in three and irregular enhancement in two cases. There were hydrocephalus in all pineal teratoma, but neither surrounding edema nor surrounding tissue invasion was seen. Low signal intensity rim was noted the solid component of all tumors and they were not enhanced. MRI showed multicomponent of intracranial teratoma including the solid and cystic component, and low signal rim which might be the characteristic finding of the intracranial teratoma.

    Full Text Available Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas. Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG. Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day. Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered.

    Full Text Available : Collision tumors involving ovaries are extremely rare. Here, we report this rare entity in a 23 years old primigravida presented with 12 weeks pregnancy and abdominal pain. Ultrasonography showed large right adnexal mass measuring 20 x 13 cm. having solid area with multiple cysts and bulky left ovary of 6 x 4.6 cm. Normal ovarian tissue was preserved after bilateral ovarian cystectomy. Grossly, right ovarian tissue revealed multiloculation and mucin filled cysts. Left ovarian cyst was filled with hairy pultaceous material. Histological diagnosis of collision tumor of right ovary comprising hemorrhagic mucinous cystadenoma and benign cystic teratoma along with dermoid cyst in left ovary was rendered. The pathogenesis of association of mature cystic teratoma with a mucinous cystadenoma has yet to be answered and the choice of management necessitates a weighing of risks based on characterization of the adnexal mass and gestational age.

    2009-06-01

    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin.

    Full Text Available Teratomas are germ cell tumors, manifested with a great variety of clinical features; the most common extragonadal site is the anterior mediastinum. In this case, we report the patient with a large mature mediastinal teratoma with several components of ectodermal and endothermal epithelium. A 24-year-old female patient presented with history of persistent chest pain and progressively aggravating dyspnea for the previous 3 months. A chest X-ray showed a large opacity of the entire left hemithorax. Transcutaneous needle aspiration revealed a purulent fluid. The tube thoracostomy was introduced and the effusion was evacuated. Some weeks later, patient was seen in emergency for persistent cough and lateral chest pain. CT scan revealed a mass of the left hemithorax. The mass showed heterogeneous density, without compressing mediastinum great vessels and left hilar structures. Lipase value was elevated in needle aspiration. The patient underwent a total resection of the mediastinum mass via a left posterolateral thoracotomy. Microscopy revealed a mature teratoma with cystic structures. The patient subsequently made a full recovery. This case provide benign mediastinal teratoma with total atelectasis of left lung and elevated lipase value in needle transcutaneous aspiration; this event is explained by pancreatic component in the cystic tumor. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent.

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

  7. Case report: Varicosity of the communicating vein between the left renal vein and the left ascending lumbar vein mimicking a renal artery aneurysm: Report of an unusual site of varicose veins and a novel hypothesis to explain its association with abdominal pain

    2011-01-01

    Full Text Available A communicating vein between the left renal vein and the left ascending lumbar vein has only rarely been reported in the imaging literature. There are very few reports of varicosity of this communicating vein. Nonetheless, awareness about this communicating vein is of utmost importance for surgeons performing aortoiliac surgeries and nephrectomies as it may pose technical difficulties during surgery or cause life-threatening retroperitoneal hemorrhage. Varicosity of this venous channel may be mistaken for paraaortic lymphadenopathy, adrenal pseudo-mass, or renal artery aneurysm. We report a case of a patient with varicosity of this communicating vein, which mimicked a left renal artery aneurysm. A novel hypothesis is also proposed to explain the relationship with abdominal pain.

    Full Text Available Teratomas are germ cell tumors containing one or more of the three embryonic layers (endoderm, mesoderm, and ectoderm. In neonates, the sacrococcygeal region is the most frequent site of origin, followed by the gonads and mediastinum. While most mediastinal teratomas are anterior, approximately 3–8% are found within the posterior mediastinum. Here we report the case of an infant who presented in the second week of life with frequent emesis followed by choking, dyspnea, and perioral cyanosis. An esophagram demonstrated a large pedunculated polypoid mass within the lumen of the esophagus. CT confirmed a 5 × 1.8 cm intraluminal mass with a stalk originating from the posterior wall of the esophagus at C6. Endoscopic retrieval was not possible due to its large size. The mass was operatively resected via a right-sided, 2 cm transverse cervical incision. An oblique esophagotomy was made; the polypoid mass was grasped and eviscerated using serial traction sutures. The mass was excised along with a rim of normal esophageal mucosa. Final pathology demonstrated a mature and solitary esophageal teratoma. To our knowledge, this is the first reported case of an intraluminal cervical esophageal teratoma, and the youngest patient in which a pedunculated esophageal polyp has been described.

    Full Text Available Anti-NMDAR (N-methyl-D-aspartate receptor encephalitis is an immune-mediated encephalitis. It has been predominantly described in young women and is commonly associated with an ovarian teratoma. We report a case of anti-NMDAR encephalitis associated with a 7 mm ovarian teratoma that was completely resected by laparoscopic surgery. An 18-year-old woman suddenly presented with personality changes requiring her admission to the department of neurology. After that, she also showed involuntary movements, disturbance of consciousness, and central hypoventilation. As an abdominal image revealed the possibility of a right ovarian teratoma of 5×7 mm, a laparoscopic operation was performed. The macroscopic appearance of the right ovary did not show any abnormalities; nevertheless, we performed a partial resection of the right ovary, with reference to the image diagnosis, in order to spare the ovarian reserve. The 22×22 mm partially resected ovary contained an intact 5×7 mm cystic tumor. The pathological diagnosis was mature cystic teratoma with components of brain tissue. An anti-NMDAR-antibody test proved positive in both serum and cerebrospinal fluid 1 month after the surgery. From these results, she was diagnosed with anti-NMDAR encephalitis. By the administration of cyclophosphamide in addition to the operation, she recovered drastically without any of the symptoms shown before.

    Full Text Available Spontaneous ovarian teratoma was found in a seven-week-old female Chunky broiler chicken that was slaughtered for food. On post-mortem inspection, a spherical tumor mass attaching to a juvenile ovary was found in the abdominal cavity. Histopathologically, the tumor was comprised of immature mesenchymal stroma and a variety of mature tissue elements of mesodermal and ectodermal origin. In addition, there were multiple indistinguishable tissue elements, which showed no malignant cytological features but were unidentifiable as to corresponding embryological layer of origin. These heterogeneous teratoma tissues consisted of a variety of glandular, cystic, duct-like, and tubular structures, some of which exhibited a lining by a mixture of both keratinizing/non-keratinizing stratified squamous epithelial cells and cuboidal/columnar epithelial cells. The ovarian tetatoma was considered a benign and congenital one. The highly diverse differentiation of the teratoma might have manifested a morphological aspect of intrinsic character of the pluripotential germ cells during tumorigenesis.

Methods: MRI appearances of 52 cases of ovarian cystic teratoma confirmed by surgery and pathology were analyzed retrospectively. Results: All of 52 cases were confirmed as mature cystic teratoma by pathology. Of the 52 cases, 43 were unilateral, 9 cases bilateral. And 61 lesions were totally found. The diameter of lesions was 12.8 cm-2.7 cm. The appearance of MRI was mainly cystic. The cystic area of the lesion showed low signal intensity on T1WI and high signal intensity on T2WI. The wall of the cyst was smooth and enhanced after contrast medium administration. MRI revealed that 52 cases were mixed intensity and containing variety of fat signal intensity area. The accuracy of MRI diagnosis in ovarian cystic teratoma was 100%. Conclusion: Ovarian teratoma has characteristic appearances in MRI. Pelvic MRI examination for ovarian teratoma can make exact diagnosis. (authors)

    Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, m...

    Nasopharyngeal teratomas are rare congenital tumors which mainly cause neonatal respiratory difficulty or feeding problems. We report an extremely rare case of nasopharyngeal teratoma in which a 34-year-old woman experienced a foreign body sensation. Simple radiographs and CT scans revealed the presence of an exophytically growing mass with a region of fatty attenuation and a well-formed tooth in the nasopharyngeal wall. The mass was surgically removed, and found at histopathology to be a mature teratoma.

    Full Text Available Intrapericardial teratomas are rare causes of mediastinal masses in children. Pericardial teratoma is a potentially curable lesion that may become life threatening when it induces mediastinal compression and fetal hydrops. Majority of the reported cases have been diagnosed prenatally. We report a case of an infant with intrapericardial immature teratoma, which was detected in a newborn infant presenting with respiratory distress. The tumor was excised completely, and histopathological examination of the resected tumor was suggestive of immature teratoma. The patient was asymptomatic three months postoperatively.

    Full Text Available The occurrence of malignancies in somatic elements of mature cystic teratoma of ovary is rare. The malignancies that may be encountered in dermoid cyst include squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, melanoma, sarcoma, carcinoid, and germ cell neoplasms. The development of transitional cell carcinoma (TCC in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-year-old postmenopausal multiparous female patient. She presented with pain and gradual swelling of abdomen for 1 month. Abdominal computed tomography revealed a solid space occupying lesion with few cystic components at right pelvis, raising the possibility of an ovarian neoplasm. The level of CA-125 was slightly raised (56∙45 U/ml. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed. Microscopic examination showed cyst wall lined by stratified squamous epithelium. Beneath the cyst wall, a tumor mass was present, histological features of which resembled that of high-grade TCC (stage pT1aNXMX. On immunohistochemical analysis, the tumor was found to be positive for CK7 and CK20 and negative for WT-1. These results were consistent with a diagnosis of TCC arising in urothelium of mature cystic teratoma. Reporting of such extremely rare cases is important for the assessment of prognostic factors and treatment protocols.

    Retroperitoneal teratomas can have characteristic roentgenographic findings. Three children with that neoplasm had roentgenographic assessments of the tumor which revealed similar ''shard-like'' calcifications. The effect of the tumor on the kidneys produced hypertension in all the patients which abated post-operatively. Extensive imaging evaluations in similar patients seems unnecessary since the findings are virtually pathognomonic. Only a single urinary tract study and plain film investigation of the abdomen are advised prior to expeditious surgery. (orig.).

    Abstract Germ cell tumors (GCTs) represent a well-recognized group of heterogeneous neoplasms with diverse clinical, histopathological, diagnostic, and prognostic characteristics. We present a rare case of a locally aggressive, chemotherapy-resistant immature mediastinal teratoma with a peculiar histological finding of a multilineage somatic-type malignant degeneration. A 21-year-old male patient presented with a 3-week history of persistent, blood-tinged productive cough and shortness of breath. A contrast-enhanced computed tomography (CT) scan of the chest showed a heterogeneous mass occupying the right hemithorax and abutting on adjacent structures. CT-guided biopsy was consistent with immature teratoma. Combination chemotherapy with bleomycin, etoposide, and cisplatin was initiated, albeit without success; the mass showed interval progression in size, and surgical resection through clamshell incision was performed. Histological assessment of the resected mass confirmed the diagnosis of immature teratoma and revealed an extensive multilineage malignant differentiation into sarcomatous, carcinomatous, and melanomatous components. The patient underwent an uneventful recovery but presented 2 months later with extensive liver and bone melanomatous metastases. In this report, relevant findings from the literature are also highlighted. Despite being exceptionally rare, such tumors carry poor prognosis. Understanding the clinicopathological characteristics and biological behavior of such tumors may provide an insight into interventions tailored to improve the otherwise dismal disease outlook.

    Abdominal pain is one of the most common complaints by patients, and assessment of abdominal pain and associated symptoms can be challenging for home healthcare providers. Reasons for abdominal pain are related to inflammation, organ distention, and ischemia. The history and physical examination are important to narrow the source of acute or chronic problems, identify immediate interventions, and when necessary, facilitate emergency department care.

    Full Text Available Abstract Background Primary carcinoid tumor arising within mature teratoma of the kidney is extremely rare, and their clinicopathologic features are not well described. Our objective was to further define the clinical features and pathologic spectra of primary carcinoid tumor arising within mature teratoma of the kidney. Methods Six previously reported case reports were identified using MEDLINE and a subsequent bibliographic search of all pertinent reports and reviews was performed. We also searched the electronic medical archival records of our institution and identified one additional unreported case. Data were extracted on the demographics, predisposing factors, clinical presentation, radiographic features, gross pathology, microscopic pathology, immunophenotype, therapy, and outcome of each of these seven cases. Results Primary carcinoid tumor arising within mature teratoma of the kidney was found at a mean age of 41.4 years. Of the 7 cases, 3 were female and 4 were male. Two of the 7 cases (28.6% were associated with horseshoe kidney. It typically presented with abdominal pain without carcinoid syndrome. It typical radiologic appearance was well circumscribed partly calcified Bosniak II-III lesion. Histologically, the carcinoid tumor showed monotonous small round cells arranged in classic anastomosing cords/ribbons intermixed with solid nests. Surgery was curative, no additional treatment was required, no local recurrences occurred, and no metastases occurred in all 7 cases. The 3 cases with available outcome data were alive at the time of publication of their respective cases (mean, 5 months. Conclusion Primary carcinoid tumor arising within mature teratoma of the kidney is a rare tumor that typically presents with abdominal pain without carcinoid syndrome. It is not associated with local recurrence and metastasis, is surgically curable, and has excellent prognosis.

  5. Abdominal trauma

    International Nuclear Information System (INIS)

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

  6. Abdominal trauma

    International Nuclear Information System (INIS)

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

    International Nuclear Information System (INIS)

    To review abdominal ultrasonography in Yersinia Pseudotuberculosis(YP) infection. From June 1993 through June 1994, abdominal ultrasonograms were reviewed in 36 patients with YP infection. The age of patients was from 4 to 14 years. A diagnosis of YP infection was made on the basis of isolation of YP from stool (n=15/36, 41.7%) and by documenting at least a minimum agglutination antibody titer of 1;160 or greater (n=34/36, 94.4%). Abdominal US findings were identified in 33/36 (91.7%) of patients with YP infection. US abnormalities included right lower quadrant abdominal lymphadenopathy in 28/36 (77.8%) of cases: increased bilateral renal cortical echogenecity with renal enlargement, 11/36 (30.6%) of cases:hepatosplenomegaly, 6/36 (16.7%) of cases: bowel wall thickening in termnal ileum and cecum, 4/36 (11.1%) of cases:and ascites, 2/36 (5.5%) of cases. Three patients revealed no abdominal sonographic finding. We conclude that abdominal US can help in the diagnosis of YP infection when US demonstrates multiple right lower quadrant abdominal lymphadenopathy, increased renal cortical echogenecity with renal enlargement, hepatosplenomegaly, intestinal wall thickening or ascites

    To compare CT and US features of immature and mature teratomas of the ovary. We retrospectively reviewed CT and US findings of 11 patients with immature teratoma and 18 patients(20 cases) with mature teratoma. The tumors were classified into three groups on the basis of image findings : predominantly cystic(type I), predominantly solid(type II), and mixed cystic and solid(type III). All eleven cases of immature teratoma were of the mixed type(type III), showing multiple small(less than 2cm) nodular and linear calcifications and fatty nodules within the solid component and adjacent to the septa of the cystic component of the masses. In contrast, mature teratomas were predominantly cystic in six cases, predominantly solid in eight, and mixed in six cases. In five of six mixed type mature teratomes, calcified fatty nodules were fewer and larger than in immature teratomas. Immature teratoma may be diagnosed by the demonstration on CT or US of multiple small(less than 2cm) nodular and linear calcifications and fatty nodules in the solid and cystic components of the tumor.

    Malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. These tumors are rapidly growing and can metastasize. We report a case of 13-yr-old girl who presented at SHKM GMC, Nalhar, Mewat, Haryana, India in December 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature teratoma and embryonal carcinoma. This report illustrates the aggressiveness of this tumor and emphasises the need of early diagnosis and treatment. PMID:26870146

  19. US Diagnosis of Mature Cystic Teratomas of the Ovary:Morphologic Analysis of 112 Pathologically Proven Cases

    International Nuclear Information System (INIS)

    To establish the morphologic US classification of mature cystic teratoma of the ovary and document the reliable sonographic features in the diagnosis of this neoplasm. The study subjects comprised 103 patients with 112 pathologically proven, mature cystic teratomas. All patients underwent preoperative pelvic US in trans abdominal and/or trans vaginal approach. One radiologist retrospectively analyzed the US findings and the tumors were classified into 6 groups based on the morphologic US features. For each tumor, additional US findings, including posterior sonic shadowing, fat-fluid level and vascularity, were also evaluated. The common US patterns were hyper echoic area within a cyst (type IV: 36 tumors,32.1%), solid and cystic mass (type V: 32 tumors, 28.5%), and a diffusely hyper echoic mass (type VI: 25 tumors, 22.3%). All solid and cystic masses (type V) showed hyperechogenicity in at least one solid portion, resulting in hyperechogenicity within a mass being seen in 93 of the 112 tumors (83.0%), with pure cystic masses (types I-III) accounted for the remaining 19 tumors (17.1 %). Of the 112 tumors, 68 (67.1%) showed posterior sonic shadowing which was demonstrated only in the hyper echoic area of types IV-VI. Any adnexal masses representing a hyper echoic area within a cyst, solid and cystic tumors containing hyperechogenicity or diffusely hyper echoic mass, especially when accompanied by posterior sonic shadowing, should be suspected as indicative of mature cystic teratoma

    Teratomas are among the most common tumors of childhood, but craniofacial teratomas are rare. They can be diagnosed antenatally. Craniofacial teratomas may cause airway obstruction in the newborn. We present a case of a newborn male child who was diagnosed to have a facial tumor in the 8th month of gestation. He was delivered normally and had no respiratory or feeding difficulties. He was also found to have a cleft palate. Serum alpha fetoprotein levels were normal. He underwent excision on day of life 9. At 11 months follow-up, he is well with no evidence of recurrence and good functional outcome.

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Mature teratoma of the pancreas is an unusual tumor. Like all teratomas it results from abnormal embryonal development of toti potent cells. Their contents may vary and may consist of ectodermal, endodermal, and mesodermal tissues. The radiologic appearance of these lesions depends on the proportions of various tissues of which they are composed. We report, to our knowledge, the first description of its CT and MR appearances.

    Ovarian teratomas (OTs) are the most common germ cell neoplasm. They include mature cystic teratomas, monodermal teratomas (neural tumors, struma ovarii, carcinoid tumors) and immature teratomas. Teratomas are the most common benign ovarian neoplasms in women less than 45 years old. OTs are usually characterized by ultrasound (US) and magnetic resonance (MR) whereas they are usually an incidental finding on CT. The purpose of this paper is to review the most common types of teratomas and to describe CT, US and MR imaging features of the various types of mature and immature OTs.

    Full Text Available Abstract Introduction Teratoma is a tumor that usually arises from one or more germ layers. They are most commonly found in the sacrococcygeal region and have a female preponderance. We present a very rare case of a boy with a benign cystic teratoma in the lumbosacral region. Case presentation A 16-year-old Indian boy presented to our hospital with a history of a lump in the lower back region since birth. Initially, it was small, but its size increased gradually over time to a size of 15 cm × 15 cm at presentation. There were no other associated abnormalities. Investigations revealed the lump to be a benign cystic teratoma. The patient underwent surgery, and the whole tumor, from its base to the vertebrae, was excised. Bisection of the tumor revealed that it contained hair and pultaceous material consistent with a teratoma, which was later confirmed by histopathologic examination. Conclusion Benign cystic teratomas should be diagnosed and managed aggressively because they generally have a greater tendency to progress toward malignancy. After extensively searching the case report database, we arrived at the conclusion that this was a rare case of a benign cystic teratoma in the lumbosacral region in a boy.

    Full Text Available ABSTRACT : Teratomas are the germ cell tumors composed of mul tiple cell types derived from one or more of the three germ layers.Teratomas rang e from benign well differentiated [mature] cystic lesions to those that are solid and malignan t [immature].Additionally, teratomas may be monodermal and highly specialized. Rarely, within so me mature teratomas, certain elements like squamous component undergo malignant transform ation.Teratomas are known to occur at birth and are derived from pleuripotent germ cells and embryonic cells. Teratomas of embryonic origin are congenital and are seen in the midline of the body – skull, neck, mediastinum, retroperitoneum, and coccyx.Teratomas d erived from the germ cells are seen in testis in men and ovaries in women. AIMS: This prospective and retrospective study was conducted to determine the frequency of the teratom as occurring in various sites along with their histomorphological presentations. MATERIALS AND METHODS : The study was conducted at Rajarajeswari Medical College and Hospi tal between January 2010 to December 2012 in the Department of Pathology. Morphological an d histopathological features of teratomas were studied. RESULTS: Teratomas were more common in females between 25- 35yrs.Most of the teratomas were seen in ovaries f ollowed by retroperitoneum and sacrococcygeal region.87% of teratomas diagnosed we re of mature cystic teratoma with histologic grading 0 and remaining 13% showed malig nant transformation. CONCLUSION: Mature teratomas are typically benign and found mor e frequently in women and there is risk of malignant transformation.

    Roughly 1% of mature cystic teratomas undergo malignant transformation. In particular, cutaneous-type adnexal neoplasms may occur in mature cystic teratomas. Sebaceous carcinomas, which arise from mature cystic teratomas, have rarely been observed, with only seven cases previously reported. Here, we present a case of a 69-year-old female who had pelvic pain for two weeks and who subsequently underwent bilateral salpingo-oophorectomy and hysterectomy. Her left ovary showed a unilocular cyst, measuring 22.0 cm in diameter, filled with sebaceous material and a few hairs. A luminally-protruding solid mass measuring 4.0 cm in diameter was also noted. Microscopic findings revealed lobular or diffusely arranged basophilic, atypical sebaceous cells connected to a typical mature cystic teratoma. Tumor cells demonstrated positive immunoreactivity for high molecular weight cytokeratin, cytokeratin 7, cytokeratin 19, epithelial membrane antigen, and carcinoembryonic antigen. Here, we present a case of sebaceous carcinoma arising from a mature cystic teratoma along with a review of previously published reports. PMID:24009635

    Primary malignant mediastinal teratoma is a rare tumour previously regarded as inevitably fatal. In a series of eight male patients with a mean age of 24 years five remain alive and well. All patients showed raised serum concentrations of human chorionic gonadotrophin or alpha fetoprotein. The patients were treated with intermittent combination chemotherapy that included cisplatin. Six patients responded to chemotherapy with a fall in human chorionic gonadotrophin or alpha fetoprotein to near normal levels and they then had radical excision of the remaining tumour. Living malignant tumour was found in four of the specimens and these patients received postoperative chemotherapy. One patient died after eight months and the remaining five patients are alive and well 13-136 months after the start of treatment. The two patients who did not undergo surgery died at one month and 15 months. Intermittent combination chemotherapy and carefully timed radical excision of these tumours would appear to have produced better results than have been reported in other series. PMID:6198739

    Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI. (orig.)

    Full Text Available Mature teratomas are the most common type of mediastinal germ cell tumors. They typically occur in young adults (15 to 35 years and 95% of these teratomas occur in the anterior mediastinum. Herein, we report a case of a huge mediastinal teratoma in a 16-year-old boy who presented with a history of chest pain, cough, exertional dyspnea, and fever. Chest X-ray and spiral computed tomography (CT revealed a bulky mass of 20×15 cm in the right side of the posterior mediastinum. The operative finding was a large cystic mass in the posterior mediastinum adherent to the neighbor organs. The cyst was filled with sebum, hair and calcified materials. The resected tumor was in the posterior mediastinum, although most of these tumors occur in the anterior mediastinum. To the best of our knowledge, this is the first documented report in Iran.

We report the first use of radiofrequency coblation in the management of such tumours. Case Report. A premature baby with a perinatal diagnosis of a large, obstructing nasooropharyngeal mass was referred to the ENT service for further investigations and management. The initial biopsy was suggestive of a neuroblastoma, but the tumour demonstrated rapid growth despite appropriate chemotherapy. In a novel use of radiofrequency coblation, the nasooropharyngeal mass was completely excised, with the final histopathology revealing a congenital nasopharyngeal teratoma. Conclusion. We report the first use of radiofrequency coblation to excise a congenital nasopharyngeal teratoma and discuss its advantages.

Results A literature search yielded 9 cases of stage III adenocarcinoma with malignant transformation. Six of these 9 patients died within 12 months after diagnosis. Of the 8 patients who underwent postoperative chemotherapy, 3 survived for over 39 months. The review indicates that prognosis of adenocarcinoma is as poor as that for squamous cell carcinoma arising from a MCT. Conclusions In general, as with this case, prognosis of advanced adenocarcinoma associated with a MCT is poor. However, we should be aware that not all patients are resistant to chemotherapy.

    A teratoma is a benign tumor containing a mixture of differentiated tissues and organotypic derivatives of the three germ layers, while a teratocarcinoma also contains embryonal carcinoma cells (EC cells). Experimental teratomas and teratocarcinomas have been derived from early mammalian embryos transplanted into the adult animal (ectopic sites). In the rat, the pluripotency of the transplanted epiblast was demonstrated and a quantifiable restriction of developmental potential persisted after subsequent transplantation of chemically defined cultivated postimplantation embryos. The rat is nonpermissive for teratocarcinoma development and rat pluripotent cell lines have been established only recently. Transplantation of mouse embryos, epiblast, or embryonic stem cells (mESCs) gave rise to teratocarcinomas. The pluripotency of reprogrammed human cells has been tested by a 'gold standard' trilaminar teratoma assay in immunocompromised mice in vivo. Human pluripotent stem cells proposed for use in regenerative medicine such as human embryonic stem cell (hESC), human nuclear-transfer/therapeutic cloning embryonic stem cell (NT-ESC), or human induced pluripotent stem cell (hiPSC) lines, once differentiated in vitro to the desired cell type, should be again tested in a long-term animal teratoma assay to exclude their malignancy. Such an approach led to a recently implemented human therapy with retinal pigmented epithelium. For greater biosafety, the teratoma assay should be standardized and complemented by assessments of mutations/epimutations, RNA/protein expression, and possible immunogenicity of autologous pluripotent cells. Furthermore, the standardized teratoma assay should be directed more to the assessment of EC/malignant cell features than of differentiated tissues, especially after a unique case of human therapy with neural stem cells was found to lead to malignancy.

    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.)

    2013-09-01

    Full Text Available Giant mature teratomas (>20 cm in diameters sometimes may contain malignant immature elements or tissues. These small foci of immature tissues could be missed at frozen section resulting inadequate initial surgical intervention. There is no large series in the literature either showing the accuracy of frozen section on huge ovarian teratomas or concerning the adequate surgical approach at the initial surgery for giant immature teratomas diagnosed as mature cystic teratomas at frozen section in patients with elevated tumor markers. We presented a case with unilateral giant immature ovarian teratoma and peritoneal gliomatosis which diagnosed as mature cystic teratoma at frozen section. Although elevated tumor markers (CA-125, AFP, CA-19,9 CEA, and lactate dehydrogenase, ascites and peritoneal implants were suggested malignant disease, staging surgery was not performed due to the benign report of frozen section. Since the patients having peritoneal implants of mature glial tissue have an excellent prognosis regardless of the grade of the ovarian teratomas, it may be suggested that surgical staging at the initial operation may not be performed in patients with giant immature teratoma diagnosed as mature teratoma at frozen section despite to the elevated tumor markers, presence of ascites or mature peritoneal implants. seems that using it in infertile patients has beneficial effects.

    We report our experience with prostatic-type tissue in ovarian teratomas, and in particular we highlight a case of prostatic-type adenocarcinoma arising within a mature cystic ovarian teratoma in a 32-yr-old woman. On gross examination, the cyst consisted of typical features of a dermoid cyst. Closer examination revealed a single 1.5-cm solid nodule within the cyst. Microscopically, it was composed of a small cyst-like structure lined by urothelium and to one side glandular and stromal tissue consistent with prostate parenchyma. Within the prostatic-type tissue, there were malignant glands morphologically and immunohistochemically supportive of prostatic-type adenocarcinoma Gleason score 3+3=6. There were also areas consistent with high-grade prostatic intraepithelial neoplasia. Although there are several reports in the literature of benign prostatic-type tissue arising within ovarian as well as testicular teratomas, to our knowledge, prostatic-type adenocarcinoma arising in a mature ovarian teratoma is an extremely rare phenomenon, with only 1 previous report in the literature.

    Teratomas are very rare intracranial tumors and cytogenetic information on this group remains rare. We report a case of a mature teratoma with abnormal +21 trisomy in tumor karyotype ocurring in a non-Down syndrome(DS) infant. Additionally, the evidence for the contribution of chromosome 21 trisomy in this neoplasia are briefly reviewed. The 6-month-old male baby presented with a posterior fossa tumor. Histological evaluation of tumor specimen showed a mature teratoma composed of fully differentiated ectodermal, mesodermal and endodermal components. Although somatic karyotyping of the index case was normal, composite tumor karyotype depicted 47,XY,+21[6]/46,XY[6]. Besides previous reports of children with DS and intracranial teratomas, this is the first report to describe the occurrence of an isolated chromosome 21 trisomy within the tumor of a non-DS child. The participation of chromosome 21 in this rare pediatric tumor, either somatic or restricted to tumor specimen,may deserve special interest and further investigation. PMID:24812702

    To differentiate mature and immature ovarian teratomas, using CT findings. The CT findings of ten mature ovarian teratomas (in one patient, bilateral) and ten which were immature were compared, using statistical analysis. Images were evaluated for size, margins, architecture, contents (mural nodules, fat, calcification), septa, local invasion and distant metastasis. These findings were compared with pathologic findings. Of the ten mature tumors, nine were well defined and predominantly cystic in internal architecture, and one was mixed. Mural nodules were found in six tumor, fat in all, distinct calcification in seven, and regular septa in three lesions. Of the ten immature humors, eight had irregular margins. Seven were predominantly solid in internal architecture and irregularly enhanced, two were mixed, and one was mainly cystic. Fat was detected in five lesions, indistinct scattered calcification in six, irregular septa in three, and local invasion of distant metastasis in four patients. Compared with mature ovarian teratomas, those that are immature tend to show CT findings of marginal irregularity, solid mass with irregular enhacement, scattered indistinct calcifications, septal irregularity, local invasion or distant metastasis. Our experience suggests that these findings may be helpful in differentiation of mature and immature ovarian teratomas.

  7. Abdominal trauma

    International Nuclear Information System (INIS)

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

  9. CT of hemodynamically unstable abdominal trauma

    International Nuclear Information System (INIS)

    This article is an appraisal of the use of CT in the management of patients with unstable abdominal trauma. We examined 41 patients with abdominal trauma using noncontrast dynamic CT. In 17 patients a postcontrast dynamic CT was also carried out. On CT, 25 patients had hemoperitoneum. Thirteen patients had splenic, 12 hepatic, 6 pancreatic, 8 bowel and mesenteric, 12 renal and 2 vascular injuries. Seven patients had retroperitoneal and 2 patients adrenal hematomas. All but five lesions (three renal, one pancreatic, and one splenic) were hypodense when CT was performed earlier than 8 h following the injury. Postcontrast studies (n = 17), revealed 4 splenic, 3 hepatic, 1 pancreatic, 3 renal, and 2 bowel and mesenteric injuries beyond what was found on noncontrast CT. Surgical confirmation (n = 21) was obtained in 81.81 % of splenic, 66.66 % of hepatic, 83.33 % of pancreatic, 100 % of renal, 100 % of retroperitoneal, and 85.71 % of bowel and mesenteric injuries. The majority of false diagnoses was obtained with noncontrast studies. Computed tomography is a remarkable method for evaluation and management of patients with hemodynamically unstable abdominal trauma, but only if it is revealed in the emergency room. Contrast injection, when it could be done, revealed lesions that were not suspected on initial plain scans. (orig.)

The reported incidence of malignant transformation in MCT is approximately 2%. A case of squamous cell carcinoma arising in a dermoid cyst of the ovary presenting at an early stage is presented here. A 53-year-old postmenopausal lady, presented with the complaint of pain in right lower abdomen since one month and a large complex abdomino-pelvic mass on examination and investigations. Final histopathology was reported as squamous cell carcinoma of left ovary arising from dermoid cyst and a benign dermoid cyst in the right ovary. The patient was assigned to squamous cell carcinoma of the ovary arising in a mature cystic teratoma, surgical stage Ic2. In view of the poor prognosis, adjuvant chemotherapy was started.

  4. MR appearance of fat distribution in ovarian teratoma. Pathologic correlation

    International Nuclear Information System (INIS)

    Magnetic resonance (MR) imaging was performed in 45 patients with 52 surgically proved ovarian teratomas. MR findings of these tumors were classified into three types depending on the degree of fatty proportions in the tumor. The majority of teratomas were filled with fatty tissue in the cystic cavity (n = 43, 82.7%). In 5 tumors (9.6%), fatty tissue was seen at the edge or within the cyst wall. Fatty tissue could not be seen in any part of the tumor in 4 cases (7.7%). The tumors without a fatty component on MR images tend to have fewer sebaceous glands and less fatty tissue within the cyst wall than tumors with an abundant fatty component. Demonstration of fatty tissue is pathognomonic for these tumors. However, tumors with a small amount of fatty tissue may be indistinguishable from cystic ovarian tumors on MR images. (author)

    Full Text Available The nephrotic syndrome (NS has been associated with a variety of malignancies in a number of reports in the literature, but has been reported in only nine cases associated with ovarian neoplasms. Membranous nephropathy is the most common glomerular pathology causing the NS in patients with solid tumors. There has been only one report of an ovarian neoplasm associated with minimal change disease (MCD. We describe the case of a 36-year-old woman who presented with the NS secondary to biopsy-proven MCD, likely secondary to mature ovarian teratoma. Treatment by tumor removal and prednisone led to remission of the NS. To the best of our knowledge, this is the first report of an ovarian teratoma and the second report of an ovarian neoplasm associated with MCD.

    A 36-year-old woman had presented with dry cough for 2 months. Thoracic computed tomography (CT) scan showed a 12 cm × 8 cm ×5 cm mass in the anterior mediastinum. Due to intimately involving the aortic arch, tumor was removed incompletely. Residual tumor remained approximate 2 cm × 3 cm × 4 cm. Histologic diagnosis was a mature cystic teratoma containing a carcinoid. Subsequently, radiotherapy (RT) was administrated on residual tumor for a total dose of 50 Gy at 2 Gy/d fraction in 25 fractions. At 2-year follow-up, the patient had stable disease. In conclusion, adjuvant radiotherapy with 50 Gy is an effective approach for residual tumor of mediastinal carcinoid teratoma. PMID:23585961

    A teratoma of the pineal region in a 20-year-old Australian Aborigine is presented in which an unusual location of the straight sinus and tentorium cerebelli suggests that the tumor arose before 4 months of gestation. In addition, this case provides some insight into the development of the falx cerebri, which might arise from the midline fusion of the left and right tentoria cerebelli caused by the dorsal development of the telencephalon.

    Full Text Available Aim: To analyse the outcome of neonatal sacrococcygeal teratomas (SCT in our setup.Materials and Methods: Hospital records of 10 neonates, who were operated for SCT during 14 years time period, were retrieved and analysed. Letters were sent to 6 parents/ caretakers of children who were lost to follow up; none of them responded.Results: Seven girls and 3 boys with a mean age of 9 days (range 1- 30 days underwent excision of SCT in the neonatal period. Antenatal pickup rates were poor (2/10. Two patients presented with tumor rupture. Though all had an obvious mass at birth, only half of them presented on day 1 of life. The remaining 5 patients came late at a mean age of 11 days. Half of the SCTs were 10 cm or larger in size. One patient was misdiagnosed as meningomyelocoele. All underwent complete excision with coccygectomy by posterior approach in prone position. There were only 2 patients who could be classified as Altman Type II, the rest were all Altman Type I. Histopathology (HPE revealed mature cystic teratoma (n=8, grade 1 immature teratoma (n=1 and grade 3 immature teratoma (n=1. There was no mortality; and complications were seen in 3/10 patients (1 neurogenic bladder, 1 major wound infection with ventriculitis and 1 minor wound infection. The mean follow up was 25 months (range 1 month to 6 years in 4 patients with no recurrence.Conclusions: Neonatal SCTs are usually benign with a good outcome after complete surgical excision with a low complication rate. Although long term follow up has been advocated, the follow up was poor in this series.

    Teratomas are neoplasms characterised by an abnormal growth of tissues derived from the three germinal layers. The term ‘teratoma’ is derived from the Greek root ‘teratos’, meaning monster. Germ cells develop in the embryo and subsequently become the cells that make up the reproductive system. During fetal development, these cells follow a midline path and descend into the pelvis as ovarian cells or the scrotal sac as testicular cells. The presence of germ cells in extragonadal sites is becau...

    Full Text Available In this report we aimed to present a case with testicular mature cystic teratoma via clinical, surgical, and histopathological findings. A 10-years-old boy complaining of left scrotal swelling for the last two years admitted to our department. Physical observation revealed a painless, firm, smooth surfaced scrotal swelling. The distention of the left hemiscrotum did not allow the palpation of the testicle. At the preoperative period the case was considered as a non-communicating hydrocele. Surgical exploration was done via a left sided inguinal incision. Surgical exploration revealed a thick capsulated mass with a diameter of 10x8x6 cm. The mass was containing hairy pieces, gelatinous fluid and tooth like calcifications no testicular tissues present. The mass was totally excised. Histopathological examination of the specimen revealed a mature cystic teratoma. If testes could not be palpated or the swelling of the scrotum could not allow making the physical examination, mature cystic teratoma that is a rare cause of testicular mass should be considered.

  12. Angiographic assessment of renal artery pathology: how reliable

    International Nuclear Information System (INIS)

    The accuracy of the angiographic interpretation of the histologic type of renal artery stenosis was assessed using a renal pathologist's diagnosis as the gold standard. The angiograms of 42 renal artery stenoses were interpreted without other information, except age and gender, independently by six angiographers. This assessment indicated that angiography is not an accurate means by which to distinguish between the individual types of fibromuscular disease of the renal artery. However, it is a fairly accurate means by which to distinguish fibromuscular disease in general from atherosclerosis of the renal artery, 207 (82%) correct interpretations of 252. In addition, in the presence of renal artery stenosis, the absence of abdominal aortic atherosclerosis on angiography is an excellent predictor of fibromuscular renal artery disease, 17 (94%) of 18 specimens. Likewise, in the presence of a renal artery stenosis, angiographically demonstrable abdominal aortic atherosclerosis is a fair predictor of atherosclerotic renal artery disease, 16 (76%) of 21 specimens

    2016-01-01

    This article focuses on various cancerous lesions that are found beyond organs in the intra-abdominal fat and can be visualized with ultrasonography. These lesions are divided into five groups. The first group includes primary benign tumors containing adipocytes, such as lipoma, lipoblastoma, hibernoma and other lesions with an adipose tissue component, such as myolipoma, angiomyolipoma, myelolipoma and teratoma. The second group comprises primary malignant adipocytecontaining tumors, including liposarcoma and immature teratoma. The third group contains primary benign tumors without an adipocyte component that are located in intra-abdominal fat. This is a numerous group of lesions represented by cystic and solid tumors. The fourth group encompasses primary malignant tumors without an adipocyte component that are located in intra-abdominal fat. These are rare lesions associated mainly with sarcomas: fibrosarcoma, malignant fibrous histiocytoma, hemangiopericytoma and leiomyosarcoma. An epithelioid tumor at this site is mesothelioma. The last but not least group includes secondary malignant tumors without an adipocyte component located in intra-abdominal fat. This is the most numerous group with prevailing carcinoma foci. For each of these groups, the authors present ultrasound features of individual lesions and discuss their differential diagnosis. In the vast majority of cases, the material for cytological and histological analysis can be obtained during ultrasound-guided procedures. This is the advantage of this imaging modality.

    Teratomas are a unique class of tumors composed of ecto- meso- and endodermal tissues, all foreign to the site of origin. In humans, the most common teratoma is the ovarian teratoma. Not much is known about the molecular and genetic etiologies of these tumors. Female carriers of the Tgkd transgene are highly susceptible to developing teratomas. Ovaries of Tgkd/+ hemizygous female mice exhibit defects in luteinization, with numerous corpora lutea, some of which contain central trapped, fully-g...

  17. Evaluation of abdominal CT in the initial treatment of abdominal trauma

    International Nuclear Information System (INIS)

    During the last four years 102 patients with abdominal trauma were examined by CT for preoperative evaluation in our hospital. In 35 patients (34 %), the CT scans revealed no abnormal findings. They were all managed conservatively except for one case of perforated small bowel. In 67 patients (66 %) CT revealed evidences of substantial abdominal or retroperitoneal trauma. In 30 of them CT findings were confirmed by surgery. Hepatic injury is usually easily recognized by CT. CT is also useful for the detection of renal or splenic injuries. The majority of those parenchymatous organ injuries were successfully managed with conservative therapy, despite apparent traumatic lesions revealed by CT. Repeat CT scans is proved to be very useful to follow the changes of these traumatic lesions. In conclusion, application of abdominal CT is extremely useful for the initial decision making in treatment of patients with abdominal trauma and for the follow-up observation of injured lesions.

    To evaluate the enhancing solid component within mature ovarian teratomas on pelvic MR examinations. Thirty-two women with surgically proven mature cystic teratomas underwent preoperative pelvic MR examinations. Five cases had an enhancing solid component within mature cystic ovarian teratomas on MR images. The MR images were retrospectively analyzed by two radiologists by consensus, focusing on the enhancing portion of tumor and the tumor itself. The study subjects include 5 patients (15.6%) with enhancing solid components within the mature ovarian cystic teratomas. The mean tumor size was 9.8 cm and they were all unilateral. The enhancing solid components of the tumors had a variable appearance and were located in the peripheral region. No cases were found to have a transmural extension or direct invasion of the neighboring pelvic organ. An enhancing solid component associated with mature ovarian teratomas is not uncommon. This finding does not however, necessarily indicate malignant transformation.

    Full Text Available Apresentamos uma revisão sobre trauma renal, com ênfase na avaliação radiológica, particularmente com o uso da tomografia computadorizada, que tem se tornado o exame de eleição, ao invés da urografia excretora e arteriografia. O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.We present a revision of the renal trauma with emphasis in the radiographic evaluation, particularly CT scan that it has largely replaced the excretory urogram and arteriogram in the diagnostic worh-up and management of the patient with renal trauma. The successful management of renal injuries depends upon the accurate assessment of their extent in agreement with Organ Injury Scaling classification. The conservative therapy managed by careful continuous observation, bed rest, appropriate fluid ressuscitation and prophylactic antibiotic coverage after radiographic staging for severely injured kidneys can yield favorable results and save patients from unnecessary exploration and possible renal loss. The indications for immediate exploratory laparotomy were acute abdomen, rapidly dropping hematocrit or associated injuries as determinated from radiologic evaluation.

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

  8. Renal trauma in adults - a pictorial review

    International Nuclear Information System (INIS)

    Full text: This review provides a framework for understanding the classification and features of renal trauma. Computed tomography (CT) is now the modality of choice in prompt diagnosis and staging of renal trauma. A retrospective review of the CT scans of all patients with blunt abdominal trauma sustaining renal injury that presented to our hospital within the last 2 years was undertaken. The patient list was obtained from our Trauma Registry database at the Trauma Services Unit. Representative cases of each category of renal injury are displayed on a poster, accompanied by explanatory notes. We also reviewed the literature on renal trauma between 1985-2001 on Medline. The indications for radiological assessment and the management of renal trauma remain controversial. Staging of renal trauma with CT imaging, when integrated with clinical information helps to facilitate appropriate management plan. Renal injuries are classified into four grades on the basis of imaging: - Grade 1: Minor cortical contusion, minor laceration with limited perinephric hematoma, and small cortical infarct. - Grade 2: Major renal lacerations extending to the medulla with or without involvement of the collecting system and segmental renal infarct. - Grade 3: Catastrophic injury which include multiple renal lacerations and injury to the renal vascular pedicle. - Grade 4: Ureteropelvic junction injuries. Diagnostic imaging and staging plays a major role in assessing patients with renal injuries and affects clinical management decisions. Understanding the radiologic classification of traumatic renal injuries and integrating the findings with clinical information assist in developing an optimal management plan.

    Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.

  13. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    Science.gov (United States)

    Stagnitti, Franco

    2009-01-01

    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

  14. Teratoma Formation by Human Embryonic Stem Cells is site-dependent and enhanced by the presence of Matrigel

    2008-01-01

    When implanted into immunodeficient mice, human embryonic stem cells (hESC) give rise to teratoma, tumour-like formations containing tissues belonging to all three germ layers. The ability to form teratoma is a sine qua non characteristic of pluripotent stem cells. However, limited data is...... available regarding the effects of implantation site and the methods employed for implantation on the success rate of teratoma formation. In the present study, the rate of teratoma formation in immunodeficient mice was site-dependent: sub-cutaneous (25-100%), intratesticular (60%), intra-muscular (12.......5%) and under the kidney capsule (100%). Co-injecting the hESC with Matrigel increased subcutaneous teratoma formation efficiency from 25% to 100%. We did not observe site-specific differences in the teratoma composition. However, subcutaneous teratomas were quite distinct, easy to remove and caused...

Intermittent claudication dissappeared in six of seven cases, the femoral pulse reappeared in all five; ankle/arm indices increased in seven cases; elevated blood pressure normalized in seven of eight cases. Seven patients were followed for 3 to 28 months. They were all free of symptoms from the lower extremities. In three patients with or without renal artery stenosis and with hypertension, the blood pressure decreased after PTA of the abdominal aorta only. PTA may be a valuable treatment in Takayasu's arteritis and stenosis of the abdominal aorta. (orig.)

    Postoperative acute renal failure (ARF) is a serious complication which can result in a prolonged hospital stay and a high mortality and morbidity. Underlying renal disease, cardiac diseases, nephrotoxin exposure and renal hypoperfusion are the possible predisposing risk factors which can create a high probability for the development of ARF. The incidence of ARF is highest after major vascular, cardiac and high-risk thoraco-abdominal surgery. Among the various renal protection strategies, ade...

  17. CT diagnosis of abdominal ectopic pheochromocytoma

    International Nuclear Information System (INIS)

    Objective: To discuss the value of CT in diagnosis of abdominal ectopic pheochromocytoma. Methods: CT findings of 5 cases surgically and pathologically proved with ectopic pheochromocytoma were retrospectively analyzed. Results: Soft tissue mass with light asymmetry enhancement was found between the abdominal aorta and the inferior vena ca-va in one case. 1 case was completely cystic with light enhancement of the cystwall located in front of the left side of the abdominal aorta. 1 case of large solid mass occurred between the renal hilum and the tail of pancreas, with irregular shape, unclear boundary, central necrosis, calcification and obviously enhancement at the solid part. 2 cases showed as oval soft lump with even density, moderate strengthening located before the abdominal aorta. Paroxysmal hypertension occurred in 3 cases and didn't in 2 cases. Hypertension happened in 1 case during the operation because of stimulation. Blood pressure appeared in 1 case during and after operation. Blood and urinary catecholamine increased significantly in 4 cases. Conclusion: Ectopic pheochromocytoma mainly located surround the abdominal aorta with diverse CT performance. It is helpful for diagnosing when finding a lesion locates at the specified sites combined with typical clinical presentation. CT can not only depict small tumor, but also can show the relationship with surrounding structure, and it provides important information for the operation and prognosis. (authors)

  18. Value of dynamic contrast-enhanced MRI for tissue characterization of ovarian teratomas: Correlation with histopathology

    International Nuclear Information System (INIS)

    Aim: To analyse the value of double contrast-enhanced (DCE) magnetic resonance imaging (MRI) in addition to conventional MRI to characterize ovarian teratomas subtypes with histological correlation. Materials and methods: From January 2005 to December 2008, 38 women undergoing MRI and subsequent resection of ovarian teratomas were identified [40 mature cystic teratomas (MCT), two struma ovarii, three immature teratomas]. MRI images were analysed blindly by two radiologists according to morphological and vascular abnormalities. An experienced histopathologist reviewed all slides to determine the presence and histological composition of Rokitansky protuberances. Results: Thirty-one MCT (77%) had at least one small, regular Rokitansky protuberance presenting at an acute angle with the cyst wall. Ten out of 31 MCT did not display any enhancement on contrast-enhanced MRI related to sebaceous glands, adipose lobules, keratin, and pilosebaceous adnexa at histology. Three different time–intensity curve (TIC), types 1, 2, and 3, were related to presence of smooth muscular cells and fibrous, neuroglial, or thyroid tissue, respectively, found at histology of MCT. Type 3 TIC was also present in one struma ovarii and two immature teratomas. Conclusion: TIC types are related to the specific content of the solid tissue of ovarian teratomas but cannot be used to differentiate benign and malignant ovarian teratomas

  19. MR diagnosis of infantile teratoma in sacrococcygeal region

    International Nuclear Information System (INIS)

    Objective: To discuss the MR manifestations of infantile teratoma in sacrococcygeal region and to evaluate the diagnostic value of MR. Methods: Retrospective analysis was adopted on the MR results of 15 affected infants. Results: The tumors in 2 cases located in hip, which is mainly cystic, circular or ellipse shaped with septum and fat signal can be seen. The wall and septum of the cysts can be reinforced in contrast enhanced imaging. The tumor in 1 case located total in pelvic cavity, presenting cystic and solitary mixed signal. The solitary part, cystic wall and septum can be obviously unequally reinforced in contrast enhanced imaging. In the rest 12 cases, the most parts of tumors located in pelvic cavity and small parts in hip presenting mainly cystic and partly solitary mixed signal. The solitary part, cystic wall and septum can be reinforced in contrast enhanced imaging. Conclusion: MR can accurately display the location and shape of teratoma in sacrococcygeal region and is contribute to diagnose and differentiate benign or malignant lesion, in order to help clinician to choose operation method.

    International Nuclear Information System (INIS)

    MRI provides diagnostic information in multiple abdominal diseases in childhood. Additional information to sonographic findings can be achieved in the diagnosis of abdominal malformation as well as in several inflammatory processes. In childhood cancer imaging MRI is essential at the beginning as well as during therapy to assess response to therapy. Because of radiation protection MRI has to replace CT in abdominal imaging in children. Some technical details have to be considered when children are examined. (orig.)

  1. Abdominal ultrasound in AIDS patients

    International Nuclear Information System (INIS)

    To analyze the ultrasonography findings in abdomen in the AIDS patients in our hospital, as well as the indications for this exploration, assessing the role of abdominal ultrasound (AU). The ultrasonographic and clinical findings in 527 patients who underwent a total of 715 explorations between 1992 and 1996 were studied. Hepatomegaly and/or splenomegaly, usually homogeneous, were observed in nearly half of the studies (45%); one third of the patients with marked splenomegaly presented visceral leishmaniasis. Focal lesions in liver and/or spleen, corresponding to angiomas, abscesses, lymphomatous lesions and metastasis, were detected in 5.7% of the explorations. Thirty-five percent of the AU revealed the presence of lymphadenopathy; nodes measuring over 2.5 cm were usually related to potential treatable infection or neoplasm. Thickening of the gallbladder wall did not usually indicate the presence of acute cholecystitis unless Murphy''s sign was also detected. Bile duct dilation and wall thickening was related to opportunistic cholangitis, and the increase in the echogenicity of the renal parenchyma was linked to AIDS-related nephropathy. Despite the fact that many of findings with AU are nonspecific, we consider that this approach should be the principal diagnostic technique in AIDS patients with suspected abdominal pathology or fever of unknown origin.

    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

    Full Text Available Abstract Introduction The discovery of a mature teratoma (dermoid cyst of the ovary during ovarian stimulation is not a rare event. Conversely, we could not find any reported cases of immature teratoma in such a situation. Clinical and ultrasound arguments for this immature form are scarcely or poorly evaluated. Case Presentation We describe the case of a 31-year-old Caucasian woman with primary infertility, who developed an immature teratoma during an in vitro fertilization ovarian stimulation cycle. Conclusions Ultrasound signs of an atypical cyst during ovarian stimulation allowed us to adopt a careful medical attitude and to adapt the required surgical oncological treatment.

    Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Primary retroperitoneal teratomas are rare and present challenging management options. We report a case of unilateral primary retroperitoneal mature cystic teratoma mimicking as an adrenal mass in 54-year-old male patient. Adrenal mass complete resection was performed by flank approach using the 11th rib resection. Because of the risk of malignancy, follow-up radiographic studies were performed to ensure the oncologic efficacy of resection. The patient has been free of recurrence for longer than 12 months.

    Full Text Available Aim: Immature teratoma (IT of the ovary represents 1% of all ovarian cancers and 20% of malignant ovarian germ cell tumors. This retrospective study of 28 such cases aims to look at its morphological spectrum and to study the correlation of the grade and stage of the tumor with prognosis. Materials and Methods: A retrospective study of 28 cases of IT of the ovary was done. Neuroepithelium was graded as grade I, II and III according to the standard criteria. The presence of immature mesenchyme was also looked for and similarly graded. Results: The median age for the cases was 19 years and abdominal pain was the commonest symptom. Neuroepithelium was seen in 26 cases (6 were grade I, 13 were grade II, and 7 were grade III; and two showed immature mesenchymal tissue (IM only. IM was seen in all 28 cases, but no correlation with the grade of the IT of the ovary is found. The follow up is available in 23 cases ranging from 6 months to 78 months (median 33 months. Of these, 13 were stage I, 3 were stage II and 7 were stage III ITs. Out of 23 patients, 17 patients were alive without evidence of disease recurrence during the last follow up. Adverse events in the form of death and local recurrence occurred in 6 patients. One patient died of the disease at 7 months duration from the disease onset (stage III, grade II IT. Conclusion: Morphological spectrum of IT of ovary is varied. Immature mesenchyme was seen in all the cases of IT of ovary and its presence should prompt a careful search for immature neuroepithelium. Stage I IT of ovary has better prognosis. Combination of surgery and chemotherapy can give longer survival even in recurrent disease.

  8. Abdominal masses in infants and children: Analysis of 92 cases with special reference to radiological findings and differential diagnosis

    International Nuclear Information System (INIS)

    The abdominal tumors in children are different from those of adults in respect to age brackets, basic tumor types, sites of origin and clinical manifestations. In children carcinoma are exceedingly uncommon. Most of the tumors are embryonal in origin and teratoma make up the bulk of the remaining neoplasms. Abdominal tumors are usually silent until they have assumed tremendous size. Early detection and aggressive philosophy of management became important as the trend to cure with radiation and chemotherapy increased. In a child with an abdominal mass x-ray exams are useful and often diagnostic. The 92 cases of abdominal masses in infants and children under the age of 16, who had been treated at Severance Hospital for the duration of 14 years from 1960 to 1973 were reviewed in respect to their basic type of tumors, site of origin, age incidence as well as radiographic findings. The results may be briefly summarized as follows; 1. The commonest tumor was ovarian cyst being 25 cases which were largely encountered over the age of 12. The next common tumors were Wilms' tumor, 17 cases, hepatoma, 9 cases, neuroblastoma and hydronephrosis, 8 cases each, teratoma 6 cases, etc. 2. The retroperitoneal space including kidneys were the most commonly involved site (43.5%), of which Wilms' tumor was the commonest. 3. About 2/3 of tumors developed under the age of 6 and the commonest lesions was Wilms' tumor and the next being neuroblastoma, teratoma, ovarian cyst and so forth. 4.In all tumors except ovarian tumors and choledochal cyst, male was more frequently affected. 5. In plain abdominal 75% of neuroblastoma crossed the mid line while in Wilms' tumor only 2 cases (14%) showed midline cross. Calcific density was present in all 6 cases of teratoma (100%) as dense and discrete ossification, in 3 cases of neuroblastoma (38%) characteristically in diffuse stippled appearance and in one case of Wilms' tumor (6%), in which calcification was nonspecific. 9.

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    Objective To investigate the diagnosis and treatment of saerocoecygeal teratoma in adults. Methods The clinical data of 17 patients with sacrococeygeal teratoma confirmed by pathological examination, 9 males and 8 females, aged 20 -53, were analyzed retrospectively. Result Correct diagnosis was made pre-operatively in 13 of the 17 patients. Two cases were misdiagnosed as with leiomyoma, and 2 cases as with saerococcygeal cyst. Pathological examination confirmed the diagnosis of teratoma in all 17 cases. Thirteen patients were followed up for 1 -5 years post-operatively. Malignant change was seen in 1 case, and 1 patient died 1 year after operation. Two patients suffered a relapse and then fully recovered after re-operation, and the other 15 patients all recovered without relapse. Conclusion Saerocoeeygeal teratoma in adults usually has no typical clinical symptom and signs and is often misdiagnosed. The pathologic examination is the base to make a definite diagnosis. Complete excision is necessary to prevent local recurrence and potential malignant transformation.

    2014-01-01

    Full Text Available Mature ovarian cystic teratomas are common benign ovarian neoplasm derived from germ cells. With increasing availability of ultrasound services even in developing countries, the diagnosis of benign ovarian tumour is made earlier and the size of the ovarian tumour at diagnosis is relatively small. It is unusual to find an ovarian cystic teratoma larger than 10 cm. We report a huge mature ovarian cystic teratoma in a multipara with a history of Hansen’s disease. We conclude that, in circumstances where women have restricted access to health care, the unusual finding of mature ovarian cystic teratoma larger than 10 cm is possible due to delayed presentation for diagnosis and treatment.

  16. Computed tomography and nonoperative treatment for blunt abdominal trauma

    International Nuclear Information System (INIS)

    Studies were undertaken to determine if computed tomography (CT) could reliably assist physical examination in the initial assessment of blunt abdominal trauma, and also to examine how various abdominal injuries were managed with the guidance of CT. A total of 255 patients underwent emergency abdominal CT following blunt abdominal trauma over a period of seven years. One hundred and fifty two patients had abnormal CT scans, including 58 hepatic, 36 renal, 25 splenic and 9 pancreatic injuries as well as 67 patients with intra-abdominal hemorrhage and 21 patients with free abdominal air. A comparative study on the detection of pneumoperitoneum revealed CT to be far superior to plain radiography. One hundred and three patients had normal CT scans, all of whom were managed nonoperatively, except for three false-negative cases and two nontherapeutic cases. The patients with injury to the parenchymal organs were given nonoperative treatment if they had stable vital signs and no evidence of associated injuries demanding immediate surgery and the majority of these patients were managed well nonoperatively. CT was thus found to be a useful adjunct in the management of victims of blunt abdominal trauma, since in a rapid and noninvasive fashion, CT accurately defined the extent of parenchymal organ injury and also disclosed any other abdominal injuries.

    A 43-year-old woman was referred to our hospital for an abnormal shadow on chest X-ray. Computed tomography revealed a tumor with calcification of 9.8 cm in size at the anterior mediastinum. The infiltration into the left brachiocephalic vein and superior vena cava by tumor was suspected. Surgery was performed under a diagnosis of mature teratoma. The tumor was found to adhere firmly to superior vena cava (SVC), left brachiocephalic vein, right phrenic nerve, and the arch of the azygos vein. To ensure the blood flow, an artificial blood vessel was placed between left brachiocephalic vein and right atrium. Then SVC was clamped and the tumor was resected with the part of SVC.

    Full Text Available Ex utero intrapartum treatment (EXIT is a procedure performed during caesarean section with preservation of fetal-placental circulation, which allows the safe handling of fetal airways with risk of airways obstruction. This report aimed at describing a case of anaesthesia for EXIT in a fetus with cervical teratoma. A 30-year-old woman, 70 kg, 160 cm, gravida 2, para 1, was followed because of polyhydramniosis diagnosed at 24 weeks′ gestation. During a routine ultrasonographic examination at 35 weeks′ gestation, it was noticed that the fetus had a tumoral mass on the anterior neck, the mass had cystic and calcified components and with a size of was 10 x 6 x5 cm. The patient with physical status ASA I, was submitted to caesarean section under general anaesthesia with mechanically controlled ventilation for exutero intrapartum treatment (EXIT. Anaesthesia was induced in rapid sequence with fentanyl, propofol and rocuronium and was maintained with isoflurane in 2.5 at 3 % in O 2 and N 2 O (50%. After hysterotomy, fetus was partially released assuring uterus-placental circulation, followed by fetal laryngoscopy and tracheal intuba-tion. The infant was intubated with an uncuffed, size 2.5 endotracheal tube. Excision of the mass was performed under general anaesthesia. After surgical intervention, on the fourth postoperative day, the infant was extubated and the newborn was discharged to the pediatric neonatal unit and on the seventh day postoperatively to home without complications. Major recommendations for EXIT are maternal-fetal safety, uterine relaxation to maintain uterine volume and uterus-placental circulation, and fetal immobility to help airway handling. We report one case of cervical teratoma managed successfully with EXIT procedure.

A.TH(H-2t2) and A.TL(H-2t1) strains showed significantly greater tumor weights than A.BY(H-2b) and A.SW(H-2s) strains. The A(H-2a) strain was intermediate in tumor size. A comparison of the genic constitution of the H-2 complex in each congenic strain suggested that the H-2D locus and/or its distal regions affected the growth of embryo-derived teratomas. The teratoma induced in the B10.A(H-2a) strain was smaller than that in the A(H-2a) strain, indicating that the genetic background of the A strain is favorable for teratoma growth. Histological observations demonstrated that the existence of embryonal carcinoma cells was necessary for the growth of teratomas. A radiation-sensitive immunological factor in the recipient probably plays a role in stimulating teratoma growth.

    Mature cystic teratoma is a germ cell tumor of the ovaries and is often observed in clinical practice. However, extragonadal teratomas are rare tumors and have been reported outside the ovaries, (e.g., in the greater omentum). The mechanism underlying the development of extragonadal teratomas remains unknown. We encountered a case of extragonadal teratoma in the pouch of Douglas that appeared to be a parasitic dermoid cyst. From our experience and the literature review, we discuss the potential mechanism leading to the development of extragonadal teratomas. A 41-year-old nonpregnant woman was referred to our department due to myoma and anemia. A 4-cm asymptomatic mass in the pouch of Douglas was observed, and the patient was diagnosed with ovarian mature cystic teratoma. She underwent laparoscopic surgery, and intraoperative findings revealed that the fallopian tube was injured and torn, and a residual small ovary was observed in the left side of the ovary. A tumor measuring approximately 4 cm observed in the pouch of Douglas was extracted without rupturing. The tumor was diagnosed as a parasitic dermoid cyst by macroscopic and histopathological findings. Auto-amputation could be the underlying mechanism that leads to an isolated parasitic dermoid cyst in the pouch of Douglas. PMID:26205577

    Horseshoe kidney is a common urology anomaly, while its association with infrarenal abdominal aortic aneurysm represents a very rare condition. Surgical approach remains controversial however, we believe that the left retroperitoneal approach should be preferred in order to avoid isthmus resection with any subsequent renal infarction, urinary tract damage and to facilitate renal arteries reimplantation, when required. We present a case of voluminous infrarenal abdominal aortic aneurysm associated with horseshoe kidney, successfully treated through a left retroperitoneal approach on the retro-renal space.

  12. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    LENUS (Irish Health Repository)

    Sugrue, Michael

    2012-01-31

    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

    Full Text Available Hydronephrosis is a condition that results from complete or partial obstruction of the urinary flow. This paper reports the case of a two-year-old, mixed-breed dog diagnosed with hydronephrosis of the left kidney six months after being kicked in the thoraco-abdominal region. The diagnosis was based on radiographic and ultrasonographic examinations. Percutaneous antegrade pyelography was also performed and allowed the visualization of opacification of the left kidney, which confirmed the diagnosis. Because the exams indicated that the patient had normal renal function, nephrectomy was performed. The patient remained in good health during the postoperative period and in subsequent evaluations.

  19. Abdominal tuberculosis: Imaging features

    International Nuclear Information System (INIS)

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis

  1. Coarctation of the aorta and renal artery stenosis in tuberous sclerosis

    International Nuclear Information System (INIS)

    Among neurocutaneous disorders, coarctation of the abdominal aorta and renal artery stenosis have traditionally been associated with neurofibromatosis. We report a 5-year-old girl who was discovered to have bilateral renal artery stenosis, coarctation of the abdominal aorta, renal cysts and typical skin lesions of tuberous clerosis during the evaluation of asymptomatic hypertension. Renal vascular hypertension has not been reported previously in tuberous sclerosis. We conclude that the tuberous sclerosis complex should be expanded to include vascular malformations and the hypertension should not be assumed to be secondary to renal hamartomata or cysts in patients with tuberous sclerosis.

    Renal oncocytomas are benign tumours, often asymptomatic, and picked incidentally on radiological imaging. We present a case report of a symptomatic giant renal oncocytoma in a 61-year old man having lower back\\/right flank pain. A large right renal mass was identified on abdominal CT scan. Radiological features were not sufficient to differentiate this lesion from renal cancer. Right radical nephrectomy was performed. Typical features of oncocytoma, without evidence of malignancy, were seen on histological examination of the specimen. In this report, we discuss literature review of radiological, genetic, and pathological characteristics of renal oncocytoma.

    International Nuclear Information System (INIS)

    Out of 75 patients who were admitted to our hospital because of abdominal trauma and were undergone the procedures such as ultrasonography and/or CT scan within 24 hours of abdominal trauma due to suspected abdominal organ injury. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. We analyzed the results of 38 patients who were confirmed of diagnosis by operation, follow-up CT scan or ultrasonography. 1. In the abdominal organ injury, solid organ injury consists of 8 cases of spleen laceration, 1 of splenic subcapsular hematoma, 7 of hepatic laceration, 7 of pancreas laceration, 3 of renal laceration, and 3 of subcapsular hematoma of kidney. 2. In addition, there were 7 bowel and/or mesenteric laceration, 2 diaphragmatic hernia, and 1 urethral rupture. 3. 2 cases of retroperitoneal hematoma and 1 case in which hemo peritoneum occurred without abdominal organ injury were confirmed by follow-up CT or ultrasonography. 4. In all of the 4 patients with multiple organ injury, pancreatic laceration was associated. 5. In abdominal trauma patients, ultrasonography or CT can be used to survey rapidly the entire abdomen for possible associated injury, and be of great help to clinicians in identifying the patients who need immediate surgery or in minimizing the incidence of unnecessary emergency abdominal exploration.

    Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura.

    Full Text Available Teratomas mediastinais representam 8 a 13% dos tumores nesta região. Uma paciente de 27 anos apresentou-se com dor torácica e dispnéia de evolução arrastada. O radiograma de tórax revelou opacidade quase total do hemitórax direito, levando à suspeita de derrame pleural. A tomografia de tórax evidenciou coleção pleural heterogênea, de contornos regulares (10,1 x 11,7 cm, nos dois terços inferiores do hemitórax direito, sem envolvimento de estruturas adjacentes. Na toracotomia exploradora, pela hipótese de teratoma cístico benigno do mediastino, realizou-se ressecção total da lesão, com boa evolução pós-operatória. A apresentação atípica e grande crescimento do tumor dificultaram o diagnóstico pré-operatório.Teratomas account for 8-13% of all mediastinal tumors. A 27-year-old patient presented with chest pain and dyspnea of prolonged evolution. A chest X-ray revealed near total opacification of the right hemithorax. On a tomography scan of the chest, a collection of heterogeneous fluid, with irregular borders and 10.1 x 11.7 cm in size, was seen in the pleura of the lower two-thirds of the right hemithorax but was not encroaching on any of the adjacent structures. Based on the hypothesis that these findings represented a benign mediastinal teratoma, an exploratory thoracotomy was performed, during which such a teratoma was found and completely excised. The post-operative evolution was favorable. The atypical presentation and considerable growth of the tumor hindered the pre-operative diagnosis.

    The knowledge of vascular variations like other anatomical variations, is important during the operative, diagnostic, and endovascular procedures in abdomen. This report describes multiple variations in the upper abdominal vessels as found during the routine dissection in a 60-year-old male cadaver. The variations found were; presence of a celiaco-mesenterico-phrenic trunk, a common inferior phrenic trunk, 2 right renal arteries originating from abdominal aorta, 2 suprarenal arteries originating from the lower right renal artery, 3 right renal veins opening separately into inferior vena cava, and termination of right testicular vein into the lowest vein among the 3 right renal veins. The existence of a celiaco-mesenterico-phrenic trunk has not been reported yet. Although, other variations reported in this case exist as individual variations, a concomitant variation of them has not been reported yet. The knowledge of such variations is quite useful in planning any upper abdominal surgery. PMID:17143371

    We aimed to evaluate the risk factors for recurrence of surgically managed ovarian mature cystic teratoma (MCT). A total of 178 women with MCT managed surgically at our clinic were included in this retrospective study. The cases were followed for a minimum of 34 months. Risk factors recorded were age, gravidity, diameter of MCT, tumour markers, bilaterality, operation time and recurrence time. One hundred forty-one women (79.2%) underwent laparoscopy and the other thirty-seven patients (20.8%) underwent laparotomy. The mean age of patients with cyst recurrence was significantly lower than that of patients without recurrence (p = 0.02). There was a significantly lower median gravidity and parity in this group. The capacity of younger age, lower gravidity and parity in predicting the recurrence of ovarian MCT was analysed using receiver operating characteristic curve analysis. The cut-off value of age, number of gravidity and parity was 26, 1 and 0, respectively. In conclusion, younger age and lower gravidity and parity were predictive of recurrence due to a more conservative approach in young and nulliparous patients. Therefore, we suggest regular follow-up visits during the postoperative period, especially for younger patients and those with lower numbers of gravidity and parity. PMID:26470593

Do sexo masculino, de 22 anos de idade, com lombalgia à esquerda com algumas semanas de evolução. Recorreu ao médico assistente que solicitou estudo imagiológico por ecografia abdominal. Detectada imagem sugestiva de aneurisma da aorta abdominal. Este achado motivou a transferência para o nosso Hospital onde foi admitido consciente e orientado, hemodinamicamente estável, apresentando uma massa pulsátil epigástrica, com frémito e sopro sistólico à auscultação. Angio-TC revelou um aneurisma da artéria renal esquerda com 16 cm de diâmetro. Dada a estabilidade clínica e topografia lesional optou-se por tentar embolizar, sem sucesso, o tronco da artéria renal esquerda antes da abordagem cirúrgica. O doente foi então submetido a Nefrectomia total esquerda por via toraco-abdominal. Pós-operatório sem complicações, locais ou sistémicas. Alta ao 8ºdia, mantendo boa função renal e com níveis normais de hemoglobina. Diagnóstico de aneurisma da artéria renal confirmado por estudo anátomo-patológico da peça operatória.One case of a large left renal artery aneurysm in a young patient 22 years old is presented. He appealed to his assistant physician a few weeks after development of left back pain. Abdominal ultrasound imaging study has been requested. Suggestive abdominal aortic aneurysm was detected. This finding led to the transfer to our hospital where he was admitted conscious and hemodynamically stable. A pulsatile epigastric mass with a systolic murmur on auscultation and thrill were detected. Angio-CT scan revealed a left renal artery aneurysm, 16 cm in diameter. Given the clinical stability and lesional topography we decide a previous embolization of left renal artery, unsuccessfully. The patient underwent then left total nephrectomy, through thoraco-abdominal incision. No local or systemic complications in the postoperative

    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

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

    Teratoma formation is the gold standard assay for testing the capacity of human pluripotent stem cells to differentiate into all embryonic germ layers. Although widely used, little effort has been made to transform this qualitative assay into a quantitative one. Using gene expression data from a wide variety of cells, we created a scorecard representing tissues from all germ layers and extraembryonic tissues. TeratoScore, an online, open-source platform based on this scorecard, distinguishes pluripotent stem cell-derived teratomas from malignant tumors, translating cell potency into a quantitative measure (http://benvenisty.huji.ac.il/teratoscore.php). The teratomas used for the algorithm also allowed us to examine gene expression differences between tumors with a diploid karyotype and those initiated by aneuploid cells. Chromosomally aberrant teratomas show a significantly different gene expression signature from that of teratomas originating from diploid cells, particularly in central nervous system-specific genes, congruent with human chromosomal syndromes.

    Percutaneous radiofrequency ablation (PRFA) of renal malignancies is currently a therapeutic option for patients who are not able to undergo surgery. Some authors consider PRFA as the therapeutic standard in the treatment of renal neoplasms in non-operable patients due to comorbid conditions and in patients with mild-moderate renal failure, to preserve residual renal functionality. The use of PRFA has become more and more widespread due to a rise in the incidental detection of renal cell carcinomas with the ever-increasing use of Imaging for the study of abdominal diseases. Clinical studies indicate that RF ablation is an effective therapy with a low level of risk of complications, which provides good results in selected patients over short and medium term periods of time, however up to now few long-term studies have been carried out which can confirm the effectiveness of PRFA.

    Intra-abdominal hypertension (IAH) contributes to organ dysfunction and leads to the development of the abdominal compartment syndrome (ACS). IAH and ACS are relatively frequent findings in patiens with severe acute pancreatitis (SAP) and are associated with deterioration in organ functions. The most affected are cardiovascular, respiratory and renal functions. The incidence of IAH in patients with SAP is approximately 60-80%. There is an accumulating evidence in human and animal studies that changes of perfusion, particularly to the microvasculature, are crucial events in the progression of acute pancreatitis (AP). The perfusion of the small and large intestine is impaired due to reduced arterial pressure, increased vascular resistence and diminished portal blood flow. Bacterial translocation has been described in patients with ACS, and this may apply to patients with SAP. Approximately 30-40% of SAP patients develop ACS because of pancreatic (retroperitoneal) inflammation, peripancreatic tissue edema, formation of fluid collections or abdominal distension. Surgical debridement was the preferred treatment to control necrotizing pancreatitis in the past. However, the management of necrotizing pancreatitis has changed over the last decade. The main objective of this article is to describe the association between IAH and AP and to emphasize this situation in clinical praxis as well (Fig. 1, Ref. 38). PMID:23406186

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

    2013-11-01

    Full Text Available Growing teratoma syndrome (GTS is defined as metastatic masses during or after chemotherapy for germ cell tumors, which contain only mature teratoma components. The peritoneum of the pelvis and abdomen and the retroperitoneum are the most frequent sites of metastasis. We report a case of GTS of the ovary showing three patterns of metastasis: dissemination, lymphogenous metastasis, and hematogenous metastasis. The patient initially presented 5 years ago with a mixed germ cell tumor of the left ovary and positive cytology of ascites. After surgery and chemotherapy, mature teratomas recurred as pelvic peritoneal dissemination, a para-aortic lymph node mass, and a lung mass. Our case highlights the importance of long-term follow-up and a whole-body search. We think that our case is suggestive regarding the mechanism of critical GTS.

    Type IV sacrococcygeal teratoma is a rare pediatric tumor that is confined to the presacral area with no external component. The signs and symptoms often arise due to mass effect and compression of adjacent organs. Urinary retention is an uncommon presenting symptom in these patients. A wide spectrum of imaging findings may be encountered in cases with sacrococcygeal teratoma because of variability of tumor size and components. We hereby present a unique magnetic resonance urography finding in a type IV sacrococcygeal teratoma which caused bladder displacement. A meticulous and complete resection of tumor with special attention to the pelvic plexus led to preservation of normal voiding function and normal bowel function in this patient. PMID:27413571

    Full Text Available Abstract Background Late relapses of testicular germ cell tumor are uncommon. We report a case of cervical mature teratoma appeared 17 years after treatment of testicular teratocarcinoma. Case presentation A 20- year- old patient underwent left sided orchiectomy followed by systemic therapy and retroperitoneal residual mass resection in 1989. He remained in complete remission for 200 months. In 2005 a huge left supraclavicular neck mass with extension to anterior mediastinum appeared. Radical surgical resection of the mass was performed and pathologic examination revealed mature teratoma. Conclusion This is one of the longest long-term reported intervals of a mature teratoma after treatment of a testicular nonseminoma germ cell tumor. This case emphasizes the necessity for follow up of testicular cancer throughout the patient's life.

    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

    Full Text Available Paraneoplastic encephalomyelitis (PEM is a well-characterized neurological syndrome. Its association with ovarian teratoma is rare. A young lady presented with features suggestive of encephalomyelitis with predominant cerebellar syndrome. Magnetic resonance imaging brain was normal. Cerebrospinal fluid showed lymphocytic pleocytosis. Computerized tomography scan of the pelvis revealed a complex left ovarian cyst. With a clinical diagnosis of PEM she underwent a left salpingo-oopherectomy. This was followed by total recovery of the PEM in two weeks. The histopathology revealed immature teratoma. The interesting feature was the clinicopathological correlation between the finding of fetal cerebellar tissue in the tumor and the PEM with predominant cerebellar features.

  15. Mature and immature ovarian teratomas: US, CT and MR imaging features

    International Nuclear Information System (INIS)

    Mature cystic ovarian teratomas, also called dermoid cysts, are one of the most frequent ovarian tumors of younger female patients and are suggested when a fat-containing cystic tumor is identified on imaging. However, the presence of fat is not pathognomonic for dermoid cyst, and it may also be identified in immature teratomas, whose prognosis and treatment are different. Some imaging features are helpful to differentiate between both tumors, including the presence of enhancement on CT and MRI. Knowledge of the imaging features of these tumors allows for a confident diagnosis to be made in most cases. A few rare and less typical imaging features should also be recognized. (authors)

    Congenital teratoma is a rare condition and is a germ cell tumor composed of elements from one or more of the embryonic germ layers and contain tissues usually foreign to the anatomic site of origin. We report a case of a neck tumor diagnosed during pregnancy, initially thought to be a goiter. After birth the neck mass kept growing until it compressed the trachea and produced respiratory failure. The infant had a difficult tracheal intubation because of the compressing mass. The staff decided to surgically remove the neck mass. After that, the infant became eupneic. The histological analysis showed a mature teratoma with no atypias. PMID:26664704

    The computed tomography appearance of WT has been described by Fishman et al. and has some variation. In their series of 25 children with WT, only two tumors had regions of fat identified on computed tomography. In contrast, teratomas are composed of multiple tissues and frequently contain radiographically apparent fat as well as calcifications. This report was prompted by our recent experience with a child in whom the fat apparent on CT and ultrasound studies suggested that the mass demonstrated within a horseshoe kidney was a teratoma rather than a Wilms' tumor.

  20. Computed tomography of pediatric abdominal masses

    International Nuclear Information System (INIS)

    Ultrasonography is a very useful diagnostic modality for evaluation of the pediatric abdominal masses, due to faster, cheaper, and no radiation hazard than CT. But CT has more advantages in assessing precise anatomic location, and extent of the pathologic process, and also has particular value in defining the size, relation of the mass to surrounding organs and detection of lymphadenopathy. We analyzed CT features of 35 cases of pathologically proven pediatric abdominal masses for recent 2 years at Ewha Woman's University Hospital. The results were as follows: 1.The most common originating site was kidney (20 cases, 57.1%); followed by gastrointestinal (5 cases, 14.3%), nonrenal retroperitoneal (4 cases, 11.4%), hepatobiliary (3 cases, 8.6%), and genital (3 cases, 8.6%) in order of frequency. 2.The most common mass was hydronephrosis (11 cases, 31.4%), Wilms' tumor (7 cases, 20.0%), neuroblastoma, choledochal cyst, periappendiceal abscess (3 cases, 8.6%, respectively), ovarian cyst (2 cases, 5.7%) were next in order of frequency. 3.Male to female ratio was 4:5 and choledochal cyst and ovarian cyst were found only in females. The most prevalent age group was 1-3 year old (12 cases, 34.3%). 4.With CT, the diagnosis of hydronephrosis was easy in all cases and could evaluate of its severity, renal function and obstruction site with high accuracy. 5.Wilms' tumor and neuroblastoma were relatively well differentiated by their characteristic CT features; such as location, shape, margin, middle cross, calyceal appearance and calcification, etc. 6.Ovarian and mensentric cysts had similar CT appearance. 7.In other pediatric abdominal masses, CT provided excellent information about anatomic detail, precise extent of tumor and differential diagnostic findings. So, CT is useful imaging modality for the demonstration and diagnosis of abdominal mass lesions in pediatric patients

    Full Text Available Objective: This study aims to highlight the clinical features, investigations and treatment outcome of retroperitoneal teratomas (RPT in children. Materials and Methods: A total of eight patients (six males and two females, age range between 6 months−10 years of RPT admitted in the department of Paediatric Surgery, PGIMS, Rohtak, between 1996−2008, were studied. The patients were investigated with hematology, x-ray, ultrasound, and computerised tomography (CT of abdomen and serum alpha-fetoprotein levels in pre and postoperative period. All patients underwent complete surgical resection. In one patient, the tumour had malignant component (yolk sac and was given postoperative chemotherapy. Postoperative follow-up included serum alpha-fetoprotein in addition to clinical examination and radiological assessment to detect recurrences. Results: The tumours were located on both sides in almost equal proportion (four on right, three on left, and one bilateral]. All tumours could be excised completely preserving the kidneys in all patients. But in one patient injury to inferior vena cava (IVC occurred which was repaired successfully. Majority (7 out of 8 were histological benign, and in one yolk sac tumour was malignant component which needed chemotherapy. All children were on follow-up and one patient with malignancy lost to follow-up after three cycles of chemotherapy. In rest there was no tumour recurrence. Conclusion: RPT are rare paediatric neoplasms. As majority are benign, a complete excision preserving the kidneys, is usually curative. Serum alpha-fetoprotein is a reliable method of assessing recurrence. Malignancy in the tumour may warrant further chemotherapy.

    Human stem cells are promising sources for regenerative therapy. To ensure safety of future therapeutic applications, the differentiation potency of stem cells has to be tested and be widely opened to the public. The potency is generally assessed by teratoma formation comprising differentiated cells from all three germ layers, and the teratomas can be inspected through high-quality digital images. The teratoma assay, however, lacks consistency in transplantation protocols and even in interpretation, which needs community-based efforts for improving the assay quality. Here, we have developed a novel database OpenTein (Open Teratoma Investigation, http://opentein.hgc.jp/) to archive and freely distribute high-resolution whole-slide images and relevant records. OpenTein has been designed as a searchable, zoomable and annotatable web-based repository system. We have deposited 468 images of teratomas derived by our transplantation of human stem cells, and users can freely access and process such digital teratoma images. Approximately, the current version of OpenTein responds within 11.2 min for processing 2.03 gigapixel teratoma images. Our system offers valuable tools and resources in the new era of stem cell biology. PMID:26496950

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

    2016-04-01

    Renal elastography has become available with the development of noninvasive quantitative techniques (including shear-wave elastography), following the rapidly growing field of diagnosis and quantification of liver fibrosis, which has a demonstrated major clinical impact. Ultrasound or even magnetic resonance techniques are leaving the pure research area to reach the routine clinical use. With the increased incidence of chronic kidney disease and its specific morbidity and mortality, the noninvasive diagnosis of renal fibrosis can be of critical value. However, it is difficult to simply extend the application from one organ to the other due to a large number of anatomical and technical issues. Indeed, the kidney exhibits various features that make stiffness assessment more complex, such as the presence of various tissue types (cortex, medulla), high spatial orientation (anisotropy), local blood flow, fatty sinus with variable volume and echotexture, perirenal space with variable fatty content, and the variable depth of the organ. Furthermore, the stiffness changes of the renal parenchyma are not exclusively related to fibrosis, as renal perfusion or hydronephrosis will impact the local elasticity. Renal elastography might be able to diagnose acute or chronic obstruction, or to renal tumor or pseudotumor characterization. Today, renal elastography appears as a promising application that still requires optimization and validation, which is the contrary for liver stiffness assessment. PMID:26976058

Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

  9. The blunt abdominal trauma

    International Nuclear Information System (INIS)

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

    Full Text Available Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50-75 ml with an ejection fraction of 4-6% and an output of 750-1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61+/-0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57+/-0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    Full Text Available Background: Teratomas are tumors comprised of tissues from all three germ layers. Teratomas within the spine are exceedingly rare especially in the absence of either spinal dysraphism, congenital abnormalities of the spine, spinal surgery, or history of lumbar punctures. Virchow was the first to describe this occurrence in the spine in 1863 and since then, only a handful of cases have been reported. Case description: A 41-year-old male presented with a longstanding history of difficulty initiating micturition and lower back pain with recent onset of saddle paraesthesia and bilateral leg pain. He did not have a history suggestive of spinal trauma nor congenital abnormalities. Neurological examination was unremarkable. Magnetic resonance imaging (MRI confirmed the presence of an intradural extra axial lesion in the region of the cauda equine. At surgery, the lesion was found to be densely adherent to the conus and a subtotal resection was performed. Histological examination confirmed the lesion to be a mature teratoma. Postoperatively, he made a good recovery and there is no evidence of recurrence at one year follow-up. Conclusion: This case demonstrates that a teratoma without immature elements can be subtotally excised to reduce the risk of neurological morbidity.

    Full Text Available From the research point of view, –ovarian teratomas, especially mature ones, are an interesting group of germ-cell tumors of the ovary. The WHO classification, which is not simple but includes all tumors that arise from germ cells, emphasizes the complexity of this group. Their complex pathophysiology is also very interesting from the clinical point of view because of their frequent occurrence, especially among young women of reproductive age. Mature ovarian teratomas are benign germ-cell tumors, but in rare cases, especially when they contain solid elements, peritoneal implants may be present which can stimulate malignant processes. Dermoid cysts, a subtype of ovarian teratomas, arise from totipotential germ cells and may therefore contain elements of all three germ layers, although ectodermal structures usually predominate. Radical surgical treatment is not necessity for this type of tumor because conservative surgery usually brings full recovery. However, they make perfect material for gaining interesting information regarding oocyte maturation and such critical cellular functions as proliferation, migration, differentiation, and apoptosis. There are still no unequivocal conclusions related to the role of mutation in genes which influence the mechanisms involved in control of the cell cycle and which may play important roles in the development of ovarian teratomas. In this review the roles of the Patched/Hedgehog and PI3K/Akt pathways and cyclin D protein in the neoplastic transformations of the germ cells are described.

    The most frequent ovarian germ cell tumors are mature cystic teratomas (MCTs), composing 10–25% of all ovarian neoplasms. MCTs have the potential of undergoing malignant transformation, typically in postmenopausal women, with a frequency of 0.17–3%, with squamous cell carcinoma being the most common malignant tumor arising from MCT.

    Full Text Available An adolescent girl with raised alpha-fetoprotein (AFP levels presented with a left-sided large solid ovarian mass. Microscopically, the tumor was composed of a variety of immature and mature tissues derived from the three germ layers having very sparse (single focus of immature neuroepithelium. Few areas also showed the presence of a reticular pattern of yolk sac tumor (YST. Hence, the tumor was diagnosed as immature teratoma with microscopic foci of yolk sac elements. After 6 months of cisplatin-based chemotherapy, she developed a recurrence which was composed of mature teratoma on histology. In this case, the single focus of immature neuroepithelium caused a difficulty in labeling this tumor as an immature teratoma which otherwise resembled a mature teratoma. The raised AFP levels suggested the presence of yolk sac element, the classical form of which was seen at microscopy in only a few areas. As compared to the markedly elevated serum AFP levels, the classical yolk sac tumorous area was very limited thus advocating the view that differentiated glands with subnuclear vacuoles similar to immature endoderm represent well-differentiated forms of YST.[1

    Full Text Available Teratomas are neoplasms of the embryonic tissues that typically arise in the gonadal and sacrococcygeal regions of adults and children. Primary adult retroperitoneal teratomas are rare and demand challenging management options. We report a case of a unilateral primary retroperitoneal mature cystic teratoma mimicking an adrenal mass in a 28-year-old female patient. Complete resection of the mass was performed by a laparotomy approach. Because of the risk of malignancy, follow-up radiographic studies were performed to ensure the oncologic efficacy of resection. The patient remains free of recurrence to date.

    Teratomas are benign tumors containing cells from ectodermal, mesodermal and endodermal layers. They occur in about 1 in every 4,000 births and most commonly in the sacrococcygeal region, followed by the ovaries. Congenital epignathus teratomas are rare embryological neoplasms localised in the region of head and neck. An epignathus is found in approximately 1:35,000–1:200,000 live births. This accounts for 2–9% of all teratomas. Size and location of the neoplasm in the oronasopharynx is varia...

  6. Minimally Invasive Treatment of Small Renal Tumors: Trends in Renal Cancer Diagnosis and Management

    International Nuclear Information System (INIS)

    Renal cell carcinoma is a common malignancy causing significant mortality. In recent years abdominal imaging, often for alternate symptomatology, has led the trend toward the detection and confirmation of smaller renal tumors. This has permitted the greater use of localized and nephron-sparing techniques including partial nephrectomy and image-guided ablation. This article aims to review the current role of image-guided biopsy and ablation in the management of small renal tumors. The natural history of renal cell carcinoma, the role of renal biopsy, the principles and procedural considerations of thermal energy ablation, and the oncological outcomes of these minimally invasive treatments are discussed and illustrated with cases from the authors' institution. Image-guided ablation, in particular, has changed the treatment paradigm and, by virtue of its increasingly evident efficacy and low morbidity, now favors the treatment of smaller tumors in patients previously unfit for surgery.

    Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures. Purpose: To retrospectively determine the prevalence of nutcracker phenomenon and nutcracker syndrome seen in MDCT in consecutive patients. Material and Methods: The institutional review board approved the study and waived the requirement for informed consent. Abdominal contrast-enhanced MDCT scans were reviewed from 1000 consecutive patients. MDCT scan assessment included renal vein diameter measurements and evaluation for the presence of anterior or posterior left renal vein entrapment. Electronic medical records and urine analysis reports of patients with left renal vein entrapment were reviewed. Student's t test was used to assess differences in renal vein diameter in patients with left renal vein entrapment. Results: Left renal vein entrapment was observed in 10.9% (109), retroaortic left renal vein in 6.5% (65), entrapment of left renal vein between superior mesenteric artery and aorta in 4.1% (41), and circumaortic left renal vein in 0.3% (3) of patients. Mean diameters of right (8.8 {+-} 1.9 mm) and unentrapped left (8.9 {+-} 1.8 mm) renal veins were not significantly different (P = 0.1). The mean diameter of anterior entrapped left renal veins (10.3 {+-} 2 mm) was significantly greater (P = 0.04) than contralateral renal veins (8.6 {+-} 2.1 mm) in their widest portion. In 8.8% of patients with the left renal vein entrapment, urine analysis showed isomorphic hematuria or proteinuria with no other known cause. Varicocele and pelvic congestion were seen in 5.5% of patients with the left renal vein entrapment. Conclusion: Left renal vein entrapment is not a rare entity and renal nutcracker phenomenon might be underdiagnosed.

    To determine diagnostic values of ultrasonography in evaluation of renal colic, ultrasonographic study of 35 patients in whom renal colic was clinically suspected was undertaken. The sonographic criterion for a positive finding consisted of visualization of urinary tract calculus with posterior acoustic shadowing, with or without ureterectasis. Renal colic was correctly diagnosed by ultrasonography in 28 patients of 33 patients with proven ureteric stone, for an accuracy of 85%. Of the 33 patients with proven ureteric stone, there were 3 cases with ureteropelvic junction stone, 4 cases with abdominal ureter stone, 4 cases with iliac ureter stone, 4 cases with pelvic ureter stone and 18 cases with ureterovesical junction stone. The results show that ultrasonography in an effective initial screening test when renal colic is clinically suspected.

    Wenceslao M. Calonge, MD

    2015-02-01

    Full Text Available Summary: The upper limit of intra-abdominal pressure after closure of gastroschisis has been suggested around 20 mm Hg. An acute abdominal compartmental syndrome may produce intestinal ischemia with perforation and hepatic or renal failure. We present a case of a baby born with gastroschisis and ileal atresias 2 decades ago. The closure of the defect entailed a borderline abdominal compartmental syndrome with caval occlusion and development of collateral venous circulation. This was evidenced by a phlebographic study at the age of 8. At the age of 19, the patient continued to show a superficial, varicose net and some aesthetic concerns. This minor condition seems not previously reported. The authors intend to raise awareness about current methods for indirect assessment of intra-abdominal pressure when performing abdominal reconstruction for a gastroschisis defect.

    Full Text Available The variation in origin of the testicular artery is not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. The renal artery is known to exhibit variations in its number and position. The knowledge of this variation will help the radiologists and surgeons in avoiding clinical complication during interventions. During routine dissection teaching to first year MBBS students at Sapthagiri Medical College, Bangalore we found variation in vascular pattern of testicular and renal artery associated with renal cyst. Photographs of the variations were taken. There was high origin of left testicular artery and accessory left renal artery associated with bilateral simple renal cyst in adult Male cadaver aged around 60years.There was also prehilar division of right renal artery associated with renal cyst. Anomalies in the origin, course and number of testicular artery were observed in 4.7 percent of cases. Additional renal vessels are known as the accessory renal artery and their incidence varies between 9-76%. In the present case there was high origin of left testicular artery associated with accessory renal artery and renal cyst. This anatomical knowledge of the presence of accessory renal artery and high origin of testicular artery in this case is important for radiologists, surgeons and urologist in their clinical practice.

    Full Text Available Background. Conventional sonography is the primary imaging tool for these pregnant women who present with an ovarian teratoma. In some cases, however, sonography diagnosis is difficult. We report a case of ovarian teratoma during pregnancy diagnosed by three-dimensional Power Doppler. The cyst was removed via laparotomy without fetal or maternal complications. Three-dimensional ultrasound with multiplanar view can better discriminate a benign ovarian teratoma from complex ovarian lesions or malignant tumors. Its role is significant especially during pregnancy as it may assist in determining which patients are requiring surgery and which are not. The results of three-dimensional sonography and magnetic resonance (MR were equal but the role of MR imaging is limited in early pregnancy. Conclusions. Three-dimensional technique is a reliable diagnostic modality for preoperative assessment of an ovarian teratoma as it can be performed during the first trimester of pregnancy.

    Full Text Available Teratomas originate from the 3 germ layers, the endoderm, mesoderm and ectoderm, with varying rates of involvement . Congenital teratoma, observed in approximately 1:20.000-40.000 live births, are very rarely located in the area of the head and neck and the majority are benign malformations. The main cause of morbidity and mortality from cervical teratoma is the tumor size and its compression of the airway. This pathology may require emergency intervention postpartum and if not treated mortality-morbidity may be high. As a result prenatal diagnosis and monitoring is very important. Here we present the case of a cervical teratoma, prenatally diagnosed on 2- and 3-D (dimensional ultrasound, which required an emergency operation postpartum due to development of respiratory distress.

    The authors report a case of bilateral malignant teratoma of the mediastinum in a 40 year old female presenting with chest pain. Two separate bilateral soft tissue masses were noted in the mediastinum at imaging. On the right side, the mass was heterogeneous with large calcification and infiltration of the pericardium. On the left side, the mass was well defined heterogeneous and without evidence of local invasion. The analysis of samples obtained by US guided puncture biopsy and surgical specimen of the two masses confirmed the diagnosis of pluri-cellular malignant teratoma. Mediastinal malignant teratomas represent 1 to 5% of all mediastinal tumors. To our knowledge, no case of synchronous bilateral mediastinal teratoma has never been reported. (authors)

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    Full Text Available Primary renal osteosarcoma is an uncommon disease, which, unlike its skeletal counterpart, presents mostly in adults, and is generally diagnosed late due to its non-specific features and intra-abdominal location. Even if the disease is localized at diagnosis, it follows an aggressive course despite radical surgery and adjuvant treatment. We report a case of renal osteosarcoma in a 65-year-old female, who developed regional recurrence, and lung and bone metastases soon after radical nephrectomy for localized disease. Chemotherapy was ineffective in controlling systemic disease.

  9. Practical pediatric abdominal CT

    International Nuclear Information System (INIS)

    This course is designed to help the radiologist in a hospital setting successfully approach abdominal CT in the infant and child. Emphasis is placed on techniques necessary for a high-quality examination of the upper abdomen, as applied to common pediatric problems such as trauma, tumor, and infection. Material is presented on technical considerations, including patient sedation, preparation, and potential pitfalls and helpful hints for imaging. An emphasis is placed on dynamic scanning with table incrementation. The section on trauma focuses on an approach to imaging the abdomen in the injured child, typical injuries, patterns of injury in the upper abdomen, and why CT is the best imaging modality for blunt upper abdominal trauma. The discussion of tumor imaging reviews the appearance of typical childhood neoplasia including Wilms tumor, neuroblastoma, non-Hodgkin and Burkitt lymphoma, and disseminated solid tumors such as rhabdomyosarcoma. The authors emphasize what to look for and where, both on initial and on later (for recurrences) examinations. The discussion of infection addresses detection of abscesses and occult infections in children, as well as imaging of abscesses prior to intervention

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    Cervical teratomas are rare germ cell tumors affecting the fetus that are associated with significant morbidity and mortality due to an increased risk of airway obstruction at delivery. These tumors can commonly produce polyhydramnios that results from the fetus' impaired ability to swallow amniotic fluid. Improved rates of prenatal diagnosis through comprehensive evaluations and imaging have dramatically impacted the perinatal management of infants with this condition. Here, we report a patient diagnosed with polyhydramnios whose fetus was discovered to have a giant cervical teratoma on imaging studies. The child underwent surgical resection after having the airway secured under the uteroplacental support as part of an ex utero intrapartum treatment procedure performed at 37 weeks. The following gross pathological and magnetic resonance images demonstrate this condition and its currently accepted treatment. PMID:27468407

  2. Radiographic evaluation of the renal injuries

    International Nuclear Information System (INIS)

    Adequate radiologic demonstration of the extent of renal injury following abdominal trauma is an important guide to therapy. In general, renal injuries were classified as minor, major or catastrophic based on a combination of radiological and clinical findings. Diagnostic methods were plain abdominal film, IVP, renal angiography and rapid noninvasive methods, such as ultrasonography and CT. This study was carried out to analyze about each diagnostic modalities including the specific findings of various types and extent of trauma and correlation of these studies for the determination of best diagnostic approach. Case materials were 100 cases of renal injuries during our 5 years experience. The results were as follows: 1. Among 100 patients, men predominated over women; men 82, women 18. About one half (44 cases) of these occurred between the age of 11-30. 2. Nonpenetrating blunt trauma account for 98% of cases. Penetrating injuries were only 3 cases. 3. Associated injuries were noted in 23 cases. 4. Renal injuries were classified into 4 categories. Grade I is contusion (33 cases), II parenchymal injury without pelvocalyceal system involvement (24 cases), III parenchymal injury with pelvocalyceal system involvement (29 cases) and IV injuried involving renal pedicle (15 cases). 5.. IVP is the most common initial diagnostic modality and good for screening of patient, but only 30% of specificity is noted. 6. Renal angiography has many advantage with accurate assesment of variety of lesion and be a good guidance for decision of prognosis and therapy. 7. Ultrasonography and CT are rapid noninvasive study, valuable in assessing the specific type and extent of injury and easily evaluated the entire abdomen. But for the vascular lession, angiography is perfected than ultrasonography or CT. 8. Conservative management was done in 68 cases. Operation were performed in 33 cases and 28 cases of them were major injuries

  4. Immature teratoma of the ovary: correlation of MR imaging and pathologic findings

    International Nuclear Information System (INIS)

    The objectives of this study were to describe MR imaging findings of immature teratoma and to correlate imaging findings with histopathologic findings. The MR findings of ten patients (age range 12-29 years, mean age 19.0 years) with pathologically proven immature teratoma were retrospectively reviewed for tumor size, presence and characteristics of fatty content, presence and characteristics of solid components, and presence of ascites and implants. The MR findings were compared with gross (n=3) and microscopic (n=10) findings. Comparisons between relative amounts of solid components and histologic grades were evaluated by Spearman rank-order correlation. On MR images all lesions appeared to be fat-containing tumors with solid components consisting of numerous cysts of various sizes. Solid tissue exhibited a wide variety of signal intensities on T2-weighted images. Punctate foci of fat were identified in all lesions, whereas fatty fluid was observed only in two. Predominant fluid content exhibited signal intensities similar to simple fluid in nine lesions. Ascites was observed in six lesions, and peritoneal dissemination in three. Pathologic studies confirmed scattered foci of adipose tissue in the solid portions of all cases, and revealed numerous cystic structure formations in these solid components. The correlation coefficient between the amount of solid tissue and the tumor grade was not significant (rs=0.266). The MR images of immature teratoma tended to show aqueous fluids and the solid components consisting of numerous cysts with punctate foci of adipose tissue, whereas predominant fluid is sebaceous fluid in the vast majority of mature cystic teratomas.

The development of transitional cell carcinoma (TCC) in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-...

    An adolescent girl with raised alpha-fetoprotein (AFP) levels presented with a left-sided large solid ovarian mass. Microscopically, the tumor was composed of a variety of immature and mature tissues derived from the three germ layers having very sparse (single focus of) immature neuroepithelium. Few areas also showed the presence of a reticular pattern of yolk sac tumor (YST). Hence, the tumor was diagnosed as immature teratoma with microscopic foci of yolk sac elements. After 6 months of ci...

    Full Text Available Background Mature cystic teratoma (MCT, usually known as dermoid cysts derived from primordial germ cells. Comparing with different other types of germ cell tumors like dysgerminomas, and endodermal sinus tumors, they are most commonly observed. The aim of this study was to evaluate the prevalence, clinical and pathological characteristics; and complications of MCT of the ovary in Chitwan district, central region of Nepal. Methods A retrospective, hospital based study was carried out in all histopathologically proven cases of MCT from July 2011 to June 2014. Relevant data were retrieved from the records of Pathology Department of Chitwan Medical College-Teaching Hospital. According to the guidelines of World Health Organization (WHO, classification of ovarian tumors was done mainly based on histogenetic principles. Results Seventy four MCTs were studied from 62 patients. Majority of the patients (74.19% were in reproductive age group of 21-40years. Chief complaint was abdominal pain. Ascites was the most common complication found in 6.45% patients. The rate of torsion was 4.84%; larger tumors underwent torsion more frequently than smaller tumors (P <0.05. Right-sided tumors outnumbered the left-sided tumors. The bilaterality rate was 19.35%. Conclusion Integrated MCT accounts for 49% of all ovarian neoplasm and occur principally during the reproductive years. Postmenopausal women or children sometimes affected. Prevalence rates of torsion were relatively less. Larger tumors have more risk of undergoing torsion than smaller tumors.

  18. Comparison of radiography and ultrasonography in the evaluation of renal lesions in the dog

    International Nuclear Information System (INIS)

    Survey abdominal radiographs, excretory urograms, and nephrosonograms were obtained from 14 dogs with renal lesions. Renal enlargement was suspected on survey radiographs and confirmed by excretory urography in 13 dogs. Radiographic differentiation between a solid and cystic renal lesion was not possible in 9 dogs. Ultrasonography determined the presence of solid masses in 12 dogs, established the presence of a renal cyst in the opposite kidney in 1 dog, and revealed hydronephrosis in 2 dogs. Ultrasonography appeared to be more sensitive than radiography in differentiating the internal characteristics of renal lesions

    Full Text Available INTRODUCTION: Sacrococcygeal teratoma (SCT is an uncommon pediatric condition (1 case per 27,000 live births, nevertheless, it is the most frequent neoplasia diagnosed at fetal age. Higher access to obstetric ultrasound allows prenatal diagnosis, appropriate planning, study and multidisciplinary treatment of these patients. CASE REPORT: In a routine obstetric evaluation, patient presented a heterogeneous, cystic mass in the sacrococcygeal region. A SCT was suspected, and an elective cesarean delivery was planned to term gestational age. The patient was delivered without complications, with a 15 cm sacrococcygeal mass. Imaging revealed an Altman II SCT, and serum tumor markers were measured. By the ninth day of life, surgery was performed with tumor and coccyx complete resection, pelvic floor reconstruction and primary closure. Postoperatively, the patient made a good recovery without digestive or neurological complications. The biopsy revealed a mature teratoma with minor immature neuroepithelial foci, without atypical cells. DISCUSSION: The prenatal diagnosis in SCT allows appropriate counseling of parents, derivation to specialized centers, and could identify high-risk patients for early interruption of gestation, taking into account a mortality rate as high as 16%. Preoperative classification is important for both treatment and prognosis. There is not enough evidence to recommend chemotherapy for the treatment of mature or immature benign teratomas. In this case, close long-term follow-up will be important to rule out recurrence, and urinary and fecal incontinence.

  20. Suprasellar Mature Cystic Teratoma: An Unusual Location for an Uncommon Tumor

    2013-01-01

    Full Text Available Intracranial germ cell tumors are uncommon and account for only 0.3–3.4% of all intracranial tumors. Teratomas are a subset of these neoplasms, and their finding in brain structures is exceptionally rare, and occurrence within the skull base is quite novel. The authors report the case of a 57-year-old male patient who presented with vision changes, incontinence, ataxia, and altered mental status of 1 week’s duration. Imaging revealed a large intrasellar mass with suprasellar extension, involvement of the ventricular system, and marked hydrocephalus with the enlargement of the lateral and third ventricles. The patient underwent a pterional craniotomy/transsylvian approach for resection of the mass. Postoperative histological examination of the resected mass was confirmatory for a mature cystic teratoma. This was followed by radiotherapy, stereotactic radiosurgery, and adjuvant radiotherapy. At the most recent followup, approximately 4 years later, the patient is doing well with improved vision since the operation. This report highlights our experience with a teratoma in a very unusual location, and we review the relevant literature.

    2016-08-01

    Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10-12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade), arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area. PMID:27508272

  2. Repair of Ischemic Injury by Pluripotent Stem Cell Based Cell Therapy without Teratoma through Selective Photosensitivity

    2015-12-01

    Full Text Available Stem-toxic small molecules have been developed to induce selective cell death of pluripotent stem cells (PSCs to lower the risk of teratoma formation. However, despite their high efficacies, chemical-based approaches may carry unexpected toxicities on specific differentiated cell types. Herein, we took advantage of KillerRed (KR as a suicide gene, to selectively induce phototoxicity using visible light via the production of reactive oxygen species. PSCs in an undifferentiated state that exclusively expressed KR (KR-PSCs were eliminated by a single exposure to visible light. This highly selective cell death in KR-PSCs was exploited to successfully inhibit teratoma formation. In particular, endothelial cells from KR-mPSCs remained fully functional in vitro and sufficient to repair ischemic injury in vivo regardless of light exposure, suggesting that a genetic approach in which KR is expressed in a tightly controlled manner would be a viable strategy to inhibit teratoma formation for future safe PSC-based therapies.

  3. Blunt renal trauma in children with pre-existing renal abnormalities.

    2015-01-01

    The kidneys are the most commonly injured genitourinary organ in children following blunt abdominal trauma. Though the retroperitoneal location affords the kidneys some protection from the forces experienced in blunt abdominal trauma, the kidneys are at greater risk of injury when a disease process exposes them from their normal shielded location. In such cases, the injuries may appear to be disproportionate in relation to the severity of the trauma history, confusing the imaging findings. Recognition of both the underlying disease process as well as the manifestations of acute trauma is important; therefore, we present a pictorial essay of traumatized kidneys in children with pre-existing renal abnormalities.

    Chronic renal failure is characterised by a gradual and sustained decline in renal clearance or glomerular filtration rate (GFR). Continued progression of renal failure will lead to renal function too low to sustain healthy life. In developed countries, such people will be offered renal replacement therapy in the form of dialysis or renal transplantation.

  5. CT differentiation of renal tumor invading parenchyma and pelvis: renal cell carcinoma vs transitional cell carcinoma

    International Nuclear Information System (INIS)

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

  6. Should blunt segmental vascular renal injuries be considered an AAST grade 4 renal injury?

    2013-01-01

    Background Renal segmental vascular injury (SVI) following blunt abdominal trauma is not part of the original AAST renal injury grading system. Recent recommendations support classifying SVI as an AAST grade 4 injury. Our primary aim was to compare outcomes following blunt renal SVI and blunt renal collecting system lacerations (CSL). We hypothesize that renal SVI fare well with conservative management alone and should be relegated a less severe renal AAST grade. Methods We retrospectively identified patients with SVI and G4 CSL admitted to a Level 1 trauma center between 2003–2010. Penetrating trauma was excluded. Need for surgical intervention, length of stay, kidney salvage (>25% renal preservation on renography 6–12 weeks after injury), and delayed complication rates were compared between the SVI and CSL injuries. Statistical analysis utilized chi squared, Fisher exact, and t-test. Results 56 patients with SVI and 88 patients with G4 CSL sustained blunt trauma. Age, injury severity score, and length of stay were similar for the two groups. Five patients in each group died of concomitant, non-renal injuries. In the G4 CSL group, 15 patients underwent major interventions and 32 patients underwent minor interventions. Only one patient in the SVI group underwent a major intervention. The renal salvage rate was 85.7% following SVI versus 62.5% following CSL (p=0.107). Conclusions Overall surgical interventions are significantly lower among the SVI cohort than G4 CSL cohort. Further analysis using a larger cohort of patients is recommended before revising the current renal grading system. Adding SVI as a grade 4 injury could potentially increase the heterogeneity of grade 4 injuries and decrease the ability of the AAST renal injury grading system to predict outcomes, such as nephrectomy rate.

    Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome. PMID:18949188

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    Objective: To analyze MRI manifestations of ovarian teratomas to improve its diagnosis. Methods: MRI findings of 70 pathologically-proved ovarian teratomas in 68 patients were retrospectively analyzed. Results:Of 70 lesions,65 were matured,4 were immatured, and the remaining 1 was struma ovarii. All of the 65 mature teratomas were cystic, of which unilocular cyst was seen in 46 (71%),bilocular cyst in 11 (17%) .incompletely separated cyst in 3 (4%) and multi-locular cyst in 5 (8%). The lipid component was found in all mature teratomas with prominent lipid component in 58 tumors,main aqueous fluid cyst with small fat in 7 tumors. Rokitansky nodule, debris and hair,and calcification or tooth were seen in 38 (58%) ,58 (89%) and 20 (31%) mature teratomas respectively. All of the 4 immature teratomas were heterogeneous, predominantly solid lesion with scattered small foci of fat, cystic spaces and calcifications. One struma ovarii demonstrated a bilocular cyst without lipid component, with very low signal in one loculation on T2W imaging. Conclusion: The majority of ovarian teratomas can be diagnosed by its characteristic MRI manifestations,whereas the minority without or with small adipose material can be nonspecific.%目的:分析卵巢畸胎瘤的MRI表现,提高MRI诊断的准确性.方法:搜集经手术和病理证实的68例共70个卵巢畸胎瘤,对其MRI表现作回顾性分析.结果:70个畸胎瘤中,成熟性畸胎瘤65个,未成熟性畸胎瘤4个,卵巢甲状腺肿1个.65个成熟性畸胎瘤均为囊性,其中单房46个(71%),双房11个(17%),多房5个(8%),不完全分隔3个(4%);65个成熟畸胎瘤均见脂肪成分,其中58个(89%)肿瘤以脂肪成分为主,7(11%)个瘤内舍少量脂肪成分;38个(58%)见头结节;20个(31%)瘤内见钙化或牙齿;58个(89%)瘤内见碎屑及毛发.增强后囊壁和较大头结节强化.4个未成熟性畸胎瘤均为囊实性,为混杂实性、液性、少量脂肪和钙化信号.1个

    Purpose: To retrospectively demonstrate the specific CT findings of retroperitoneal neoplasms to diagnosis and differential diagnosis renal and non-renal tumors within the perirenal space in infants and children. Materials and methods: We retrospectively reviewed the clinical data and CT images of 42 consecutive patients with surgically and pathologically proven retroperitoneal neoplasms within the perirenal space. The patients were divided into renal tumors group (n = 16) and non-renal tumors group (n = 26). The former included nephroblastoma (n = 15) and renal lymphoma (n = 1), while the latter included neuroblastoma (n = 12), retroperitoneal teratoma (n = 6), adrenal ganglioneuroma (n = 4), retroperitoneal lymphoma (n = 2), ectopic pheochromocytoma (n = 1) and adrenal cortical carcinoma (n = 1). The clinical information of these patients and the major CT imaging findings which were related to lesion localization in the two groups were compared and statistically analyzed using Pearson Chi-Square Test and Risk Estimate. Results: The mean diameter of tumors was 9.82 {+-} 6.13 cm (n = 42 range: 2.3-32 cm). The demographic data and chief clinical symptoms between the renal tumor group and the non-renal tumor group showed no statistically significant differences (P > 0.05). 30.8% (8/26) of non-renal tumor patients presented elevated urinary vanillylmandelic acid (VMA) level, while no patient showed elevated VMA in renal tumor group (P < 0.05). Some CT imaging signs of the renal tumors including 'crescent sign' (odds ratio, OR = 52), 'beak sign' (OR = 84), 'embedded organ sign' (OR = 84), and 'prominent feeding artery sign' (OR = 36) showed significantly higher incidence when compared to the non-renal tumors (P < 0.001). The sign of 'renal displacement and renal axis rotation' (OR = 0.059) was seen in 23 of 26 (88.5%) non-renal tumors, but in only 5 of 16 (31.3%) renal tumors (P < 0.001). The sign of 'extra-renal

  1. Retroperitoneal neoplasms within the perirenal space in infants and children: Differentiation of renal and non-renal origin in enhanced CT images

    International Nuclear Information System (INIS)

    Purpose: To retrospectively demonstrate the specific CT findings of retroperitoneal neoplasms to diagnosis and differential diagnosis renal and non-renal tumors within the perirenal space in infants and children. Materials and methods: We retrospectively reviewed the clinical data and CT images of 42 consecutive patients with surgically and pathologically proven retroperitoneal neoplasms within the perirenal space. The patients were divided into renal tumors group (n = 16) and non-renal tumors group (n = 26). The former included nephroblastoma (n = 15) and renal lymphoma (n = 1), while the latter included neuroblastoma (n = 12), retroperitoneal teratoma (n = 6), adrenal ganglioneuroma (n = 4), retroperitoneal lymphoma (n = 2), ectopic pheochromocytoma (n = 1) and adrenal cortical carcinoma (n = 1). The clinical information of these patients and the major CT imaging findings which were related to lesion localization in the two groups were compared and statistically analyzed using Pearson Chi-Square Test and Risk Estimate. Results: The mean diameter of tumors was 9.82 ± 6.13 cm (n = 42 range: 2.3-32 cm). The demographic data and chief clinical symptoms between the renal tumor group and the non-renal tumor group showed no statistically significant differences (P > 0.05). 30.8% (8/26) of non-renal tumor patients presented elevated urinary vanillylmandelic acid (VMA) level, while no patient showed elevated VMA in renal tumor group (P < 0.05). Some CT imaging signs of the renal tumors including 'crescent sign' (odds ratio, OR = 52), 'beak sign' (OR = 84), 'embedded organ sign' (OR = 84), and 'prominent feeding artery sign' (OR = 36) showed significantly higher incidence when compared to the non-renal tumors (P < 0.001). The sign of 'renal displacement and renal axis rotation' (OR = 0.059) was seen in 23 of 26 (88.5%) non-renal tumors, but in only 5 of 16 (31.3%) renal tumors (P < 0.001). The sign of 'extra-renal central plane of tumor' (OR = 0.038) was displayed in 24

    Surgical exploration has been the standard of care for abdominal gunshot injuries. The authors report a case of a 28-year-old man who sustained a transabdominal gunshot injury, which entered the anterior abdominal wall and exited adjacent to the T12 vertebra posteriorly with a tangential trajectory. On presentation, the patient was haemodynamically stable with no peritoneal signs. Based on trajectory of the bullet, intra-abdominal injury was suspected. Therefore a CT scan abdomen with intravenous and rectal contrast was performed. The CT scan revealed no extravasation of the rectal contrast but showed free air specks behind the descending colon. Delayed renal images of the left ureter were also normal. Based on the clinical findings, the patient was managed non-operatively with nothing per oral, intravenous antibiotics and frequent abdominal assessments. He made an uneventful recovery without necessitating laparotomy. PMID:24272989

  8. Magnetic resonance angiography (MRA) of the abdominal veins

    International Nuclear Information System (INIS)

    On the basis of the time-of-flight effect in 18 normal volunteers and 119 patients with different diseases of the abdominal veins (inferior vena cava, portosplenic systems, renal/hepatic/iliac veins) magnetic resonanced (MR) angiograms were compared with the DSA, CT and US results. The MR technique included a series of 2D gradient-echo (Flash) images obtained which the patients held their breath and projection angiograms (PA) (MIP algorithm). PA of the inferior vena cava and renal veins had a sensitivity of 90% and a specificity of 88.8%. The results demonstrate that in all cases diseases of the large veins could be detected using all the MR information available. It is suggested that this method is so far not satisfactory in the evaluation of small vessels and slow intravascular flow conditions. (orig.)

  9. Rupture of the ureter following blunt abdominal trauma

    International Nuclear Information System (INIS)

    Two male and one female patients, between the ages of four and 25 years, involved in road traffic accidents, sustained isolated ruptures of the right proximal ureter in addition to severe injuries to the skull and extremities. The typical urographic finding of an absent ureter was seen only once. In one incomplete rupture of the ureter from a solitary kidney; the ureter filled with contrast and there was no dilatation of the renal pelvis and in another case, the appearance of the ureter was simulated by a peri-ureteric contrast leak. Ultrasound examinations following abdominal trauma should be directed at finding peri-renal fluid; this should be followed by an urogram in order to recognize ureteric rupture at an early stage, when there may be few symptoms.

  12. Updates on abdominal desmoid tumors

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

    Full Text Available Teratomas are characterized by containing tissue from all three germinal cell layers. Occasionally, somatic type malignancies develop within a mature cystic teratoma. We reported here a rare case of enteric type adenocarcinoma, with associated dysplastic epithelial precursor lesion, arising within a mature cystic teratoma in the retroperitoneum of a 30-year-old woman status post vaginal delivery 11 weeks earlier. The mass is 17.5 cm and cystic. A polypoid mass component measuring 4.7x4.2x2.5 cm was located inside the cystic component. Microscopically, the majority of the specimen was a mature cystic teratoma with all three germinal cell layers. The polypoid mass component was an adenocarcinoma with an adjacent dysplastic epithelial precursor lesion. The adenocarcinoma was diffusely positive for CK20 and CDX-2, and focally positive for CD7, indicating enteric differentiation. A brief review of retroperitoneal mature cystic teratomas with associated somatic type malignancy was performed.

  16. The role of the plain radiograph and renal tract ultrasound in the management of children with renal tract calculi

    International Nuclear Information System (INIS)

    AIMS: The aim of this retrospective study was to assess the relative efficacy of plain abdominal radiographs and detailed renal tract ultrasound (US) examination in the diagnosis and follow-up of children with renal tract calculi. METHODS: The records and imaging studies of 28 paediatric patients who had presented with proven renal tract calculi over a period of 5 years were examined. RESULTS: In 23 (82%) patients, US was the first investigation. All these patients also had plain radiographs. Plain radiographs were the first investigation in five (18%) patients. All renal calculi (100%) visible on plain films were demonstrated on US. Furthermore, detailed US often provided other clinically significant findings that were not apparent on plain films. CONCLUSION: As a result of this study it is recommend that detailed US should be the investigation of choice in children with suspected renal tract calculi. Smith, S.L. (2000)

  17. Plain abdominal radiography: A powerful tool to prognosticate outcome in patients with zinc phosphide poisoning

    International Nuclear Information System (INIS)

    Aim: To evaluate the clinical features of zinc phosphide poisoning and to investigate whether outcome could be prognosticated based on abdominal radiography on presentation. Materials and methods: All zinc phosphide-poisoned patients who were referred to Loghman-Hakim Hospital between March 2011 and September 2013 were retrospectively reviewed. Data regarding patients' demographic characteristics, characteristics of the poisoning, abdominal radiography results, and patients' outcome were recorded. Results: In 102 patients, the most common presenting signs/symptoms were nausea and vomiting (60%). Four patients died and another seven had developed complications during their hospitalization (metabolic acidosis, liver abnormalities, or acute renal failure). Nineteen patients had radio-opaque abdominal radiographs, nine of whom had died or developed complications (p = 0.001). Plain abdominal radiography had a sensitivity and specificity of 81% and 89% in predicting the patients' death or further development of complications. The positive and negative predictive values were 47% and 97%, respectively. Conclusion: Plain abdominal radiography is a very good tool for prognostication in patients with zinc phosphide poisoning. Immediate abdominal radiography can help stratify patients into high- or low-risk groups and determine treatment strategies. - Highlights: • ZP poisoning may cause severe symptoms or death although less frequent compared to ALP. • ZP-poisoned patients may deteriorate within the first 72 hours post-ingestion. • Abdominal radiography is a good tool to predict death/complications in these patients

    Sclerotic bone lesions are often seen on chest CT in adults with tuberous sclerosis complex. To characterize bone lesions at abdominal MRI in children with tuberous sclerosis complex. This retrospective review included 70 children with tuberous sclerosis complex who had undergone abdominal MRI for renal imaging. An additional longitudinal study was performed in 50 children who had had two or more MRI scans. Abdominal CT (eight children) and radiographs (three children) were reviewed and compared with MRI. A total of 173 sclerotic bone lesions were detected in 51/70 children (73%; 95% confidence interval: 0.61-0.82) chiefly affecting vertebral pedicles. New lesions appeared in 20 children and growth of previous sclerotic bone lesions was documented in 14 children. Sclerotic bone lesions were more frequent in girls and in children with more extensive renal involvement. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. They usually affect posterior vertebral elements and their number and size increase with age. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed in childhood, recognition of these lesions is useful. (orig.)

  19. Computed tomographic evaluation of renal injuries

    International Nuclear Information System (INIS)

    Adequate radiographic demonstration of the extent of renal injury following blunt abdominal trauma is an important guide to therapy. The diagnostic evaluation of renal injuries usually begins with excretory urography, but not provide detailed information about the extent of injury. The need for a more accurate noninvasive modality led us to investigate the use of computed tomography. We evaluated with computed tomography and excretory urography 30 selected patients suspected of having major renal injury. Of these patients 11 were also underwent arteriography for assessment of renal arterial injuries. In this paper, we wish to analyze the result of the above modalities, particularly angiography and computed tomography. The brief results were as follow. 1. Among 30 patients, 21 cases were male and 9 cases were female. About one third of these occurred between the age of 20-29. 2. All cases were non penetrating blunt traumas. 3. Renal injuries were categorized into 3 groups. Category I is minor renal injuries (14 cases), II is major renal injuries (13 cases), and III is catastrophic renal injuries (3 cases). 4. IVP is the most common initial diagnostic modality and good for screening of patients, but lack of specificity. In our study the specificity is about 33%. 5. CT is more accurate in detecting hematoma, parenchymal laceration, fracture and extravasation of urine, but angiography is more confirmative in diagnosis of vascular injuries. 6. Conservative management was done in 19 cases; 13 cases of category I and 6 cases of II. Operation was performed in 11 cases; 1 case of category I, 7 cases of II and 3 cases of III. 7. Associated injuries were noted in 17 cases (57%).

  20. PET/CT Interpretation: Abdominal Anatomy

    International Nuclear Information System (INIS)

    bifurcate at the pelvic brim into internal and external iliac arteries. The major branches of the abdominal aorta are celiac trunk, superior and inferior mesenteric arteries. The inferior vena cava (IVC) lies to the right of the aorta. Lymph Nodes: Normal nodes are oblong and are oriented parallel to their accompanying vessels. Abdominoaortic nodal group surround the aorta and IVC. Visceral nodes drain adjacent organs and include mesenteric, hepatic, splenic and pancraticoduodenal nodal groups. Size is the major CT criterion for diagnosis of abnormal nodes. 10 mm in short axis for abdominal or pelvic nodes or 6 mm in the retrocrural or porta hepatic are used as the cutoff. Multiple 8-10 mm nodes in the abdomen or pelvis are considered suspicious. Interpretation should be made in the clinical context and metabolism by PET and anatomic criteria by CT. Liver: The vascular anatomy of the liver defines the surgical approach to hepatic resection. A three dimensional hepatic anatomy is essential to correlate lesion location with cross sectional imaging. An international numbering system developed by Couinaud is commonly used in PET/CT report for accurate communication. There are eight functionally independent liver segments and segment 4 is divided into 4A and 4B. The middle hepatic vein divides the liver into right and left lobes. The right hepatic vein divides the right lobe of liver into anterior and posterior segments. The left hepatic vein divides the left lobe into medial and lateral part. Portal vein divides the liver into upper and lower segments. The liver segments are named in a clock wise manner. Retroperitoneal Spaces: The retroperitoneal space between the diaphragm and pelvic brim is divided into anterior pararenal, perirenal and posterior pararenal compartments by the anterior and posterior renal fascia. The pancreas, duodenal loop, ascending and descending colon are in the anterior pararenal space. The perirenal space contains the kidneys, proximal ureter and
