    Full Text Available ’n Elektrokardiogram (EKG meet die elektriese aktiwiteit van die hart op die veloppervlak. Volumegeleidingsmodelle van die toraks kan ontwerp word om hierdie metings te simuleer. ’n Generatorfunksie, wat die elektriese aktiwiteit van die hart beskryf, word benodig om hierdie simulasies aan te dryf. Hoewel soortgelyke simulasies van variërende kompleksiteit in die literatuur bespreek word, is daar ’n behoefte aan ’n vereenvoudigde, dog omvattende benadering wat kan dien as inleiding tot die onderwerp of vir gevalle waar ’n eerste-orde-benadering tot die probleem voldoende is. In hierdie artikel word ’n oorsig gegee oor die vektorinterpretasie van die EKG, ook bekend as ’n vektorkardiogram (VKG, in die tweedimensionele menslike frontale vlak. Die afleiding van die ekwivalente elektriese dipool (met ander woorde die kardiale vektor vanaf die VKG, wat gebruik kan word as ’n stroombron-generatorfunksie vir volumegeleidingsmodelle wat die EKG simuleer, word bespreek. ’n Prosedure om so ’n volume-geleidingsmodel met die eindige-element-tegniek te implementeer en die vereenvoudigde tweedimensionele generatorfunksie te gebruik, sowel as die resultate daarvan, word bespreek. Die algemene kenmerke van gemete EKG-afleidings stem ooreen met dié wat deur die eenvoudige model voorspel word.

    Choledochal cyst is a rare disease with a considerably higher incidence found in the Asian population. Although its etiology is not completely known, the disease is believed to be associated with anomalies in the anatomy of the biliary tract. While being a benign unit, it is considered as a precancerosis with the risk of conversion to the biliary tract carcinoma. Radical surgical removal with biliary tract reconstruction is the only curative solution. The authors present the case report of a patient with choledochal cyst type I according to Todani

  17. Arachnoid cysts

    Energy Technology Data Exchange (ETDEWEB)

    Agnoli, A.L.; Ellams, E.T.

    1984-11-01

    The clinical features and neuroradiological and computertomographic findings in 125 patients with cystic intracranial processes, which were neither due to tumour nor of vascular origin, have been analysed. The intrathecal injection of iodinated contrast media is absolutely essential for the differential diagnosis of congenital cysts. CT demonstration using 2 mm. slices and coronal and sagittal reconstruction makes it possible to relate the lesions to surrounding brain structures. Additional anomalies of the brain can be diagnosed and considered when planning treatment. Air studies are no longer necessary, but plain films remain the first diagnostic step. In view of modern micro-surgical techniques, angiography remains of value in order to diagnose vascular anomalies at a pre-operative stage.

  15. Calcifying odontogenic cyst with ameloblastic fibroma: report of three cases.

    Science.gov (United States)

    Lin, Cheng-Chung; Chen, Chung-Ho; Lin, Li-Min; Chen, Yuk-Kwan; Wright, John M; Kessler, Harvey P; Cheng, Yi-Shing Lisa; Ellis, Edward

    2004-10-01

    Although it is a rare event, odontogenic tumors such as ameloblastoma, ameloblastic fibroma (AF), ameloblastic fibro-odontoma, and odontoma have been reported associated with calcifying odontogenic cyst (COC). There are only four cases of COC with AF cited in the English literature. However, three of these four cases were either included in a review of a series of cases or reported as an abstract, and limited clinical and histological information was provided. We present three additional cases of COC with AF and discuss the management for this combined lesion. Because COC is known for its histologic diversity and variable clinical behavior, and the clinical significance of an association of COC with AF is still unknown, we think it is valuable to report COC with AF with detailed clinical and pathological documentation.

    Full Text Available Epidermoid cyst occurring within the tongue is rare. A 5 year old male child was brought to OPD with a tongue mass which was gradually increasing in size. There was associated difficulty in speech and mastication as the swelling increased in size. Intraoral examination revealed moderately tender, fluctuant and enlarged tongue. A diagnosis of dermoid cyst was made and the patient was booked for surgery. Excision of the cyst was done under general anaesthesia. Post-operative histopathology was done. The histopathological findings confirm the diagnosis of an epidermoid cyst, characterized by the presence of: (I a cyst cavity lined by stratified squamous epithelium with keratinization on the surface; and (II connective tissue with a mild inflammation. The proposed treatment was considered successful as the case was solved and there was no recurrence. Keywords: dermoid; epidermoid cyst;tounge. | PubMed

    A 66-year-old woman, having no complaint, admitted our clinic, because of a mass in the right superior mediastinum detected three years ago on chest X-ray. The operation was performed through the right thoracotomy in December of 1989. The thin-walled cyst located adjacent to the trachea between superior vena cava and back bones, occupied from beneath the innominate artery to the right main bronchus. The tumor (7 x 5 x 5 cm) weighing 80 grams had a smooth surface and contained watery fluid. Histological examination showed a cyst lined a monolayer of cuboidal epithelium. The cyst wall consisted of parathyroid tissue. Mediastinal parathyroid cyst is very rare. Since the first report of DeQuervain, 15 cases have been reported. These reports are reviewed.

    Full Text Available Simple bone cysts (SBC are pseudocysts occurring less commonly in the maxillofacial region. The uncertain and unclear etiopathogenesis led to numerous synonyms to refer this particular cyst. These cysts are devoid of an epithelial lining and are usually empty or contain blood or straw-colored fluid. In jaws initially it mimics a periapical cyst and later can lead to cortical bone expansion warranting for radical approach, which is seldom required. SBC is predominantly diagnosed in first two decades of life. Here we report a case of solitary bone cyst mimicking a periapical cyst of a mandibular molar in a 37-year-old patient.

    Background and Objectives: Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure. Methods: A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively. Results: Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate. Conclusion: When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

  4. Pancreas and cyst segmentation

    Dmitriev, Konstantin; Gutenko, Ievgeniia; Nadeem, Saad; Kaufman, Arie

    2016-03-01

    Accurate segmentation of abdominal organs from medical images is an essential part of surgical planning and computer-aided disease diagnosis. Many existing algorithms are specialized for the segmentation of healthy organs. Cystic pancreas segmentation is especially challenging due to its low contrast boundaries, variability in shape, location and the stage of the pancreatic cancer. We present a semi-automatic segmentation algorithm for pancreata with cysts. In contrast to existing automatic segmentation approaches for healthy pancreas segmentation which are amenable to atlas/statistical shape approaches, a pancreas with cysts can have even higher variability with respect to the shape of the pancreas due to the size and shape of the cyst(s). Hence, fine results are better attained with semi-automatic steerable approaches. We use a novel combination of random walker and region growing approaches to delineate the boundaries of the pancreas and cysts with respective best Dice coefficients of 85.1% and 86.7%, and respective best volumetric overlap errors of 26.0% and 23.5%. Results show that the proposed algorithm for pancreas and pancreatic cyst segmentation is accurate and stable.

  10. Bone cysts: unicameral and aneurysmal bone cyst.

    Science.gov (United States)

    Mascard, E; Gomez-Brouchet, A; Lambot, K

    2015-02-01

    Simple and aneurysmal bone cysts are benign lytic bone lesions, usually encountered in children and adolescents. Simple bone cyst is a cystic, fluid-filled lesion, which may be unicameral (UBC) or partially separated. UBC can involve all bones, but usually the long bone metaphysis and otherwise primarily the proximal humerus and proximal femur. The classic aneurysmal bone cyst (ABC) is an expansive and hemorrhagic tumor, usually showing characteristic translocation. About 30% of ABCs are secondary, without translocation; they occur in reaction to another, usually benign, bone lesion. ABCs are metaphyseal, excentric, bulging, fluid-filled and multicameral, and may develop in all bones of the skeleton. On MRI, the fluid level is evocative. It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. Treatment in non-threatening forms consists in intracystic injection of methylprednisolone. When there is a risk of fracture, especially of the femoral neck, surgery with curettage, filling with bone substitute or graft and osteosynthesis may be required. ABCs are potentially more aggressive, with a risk of bone destruction. Diagnosis must systematically be confirmed by biopsy, identifying soft-tissue parts, as telangiectatic sarcoma can mimic ABC. Intra-lesional sclerotherapy with alcohol is an effective treatment. In spinal ABC and in aggressive lesions with a risk of fracture, surgical treatment should be preferred, possibly after preoperative embolization. The risk of malignant transformation is very low, except in case of radiation therapy.

    Spinal hydatid cysts account for 1% of all cases of hydatid disease; primary intradural hydatid cysts are uncommon. We present a case of pathologically confirmed intradural spinal cyst hydatid in an otherwise healthy patient who showed no other evidence of systemic hydatid cyst disease. The patient presented with back pain, paraparesis, and weakness. An intradural extramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be a hydatid cyst by histopathologic examination after surgical removal. To our knowledge, this is the 25th case of hydatid cyst at an intradural extramedullary location reported in the literature.

    Accurate preoperative staging of ovarian chocolate cysts is very important because recent hormonal therapy has been effective in low stage patients. However, it has been difficult to assess the preoperative stage of ovarian chocolate cysts. We evaluated the diagnostic potential of MRI in preoperative staging of 15 overian chocolate cysts. It was well known that the older the ovarian chocolate cyst was the more iron content it had. We examined the iron contents effect on T1 and T2 relaxation times in surgically confirmed chocolate cysts (stage II: 3 cases, stage III: 3 cases and stage IV: 9 cases by AFS classification, 1985) employing the 0.15-T MR system and 200 MHz spectrometer. There was a positive linear relation between T1 of the lesion using the MR system (T1) and T1 of the resected contents using the spectrometer (sp-T1); r = 0.93. The same relation was revealed between T2 and sp-T2; r = 0.87. It was indicated that T1 and T2 using the MR system was accurate. There was a negative linear relation between T1 and the iron contents ( r = -0.81) but no relation between T2 and the iron contents. T1 was 412 +- 91 msec for stage II, 356 +- 126 msec for stage III and 208 +- 30 msec for stage IV. T1 for stage IV was shorter than that for stage II and III, statistically significant differences were noted (p < 0.05). Thus, T1 was useful in differentiating a fresh from an old ovarian chocolate cyst. We concluded that T1 relaxation time using the MR system was useful for the staging of an ovarian chocolate cyst without surgery.

    Anderson, Jada Jean; Connor, Gregory F.; Helms, Clyde A. [Duke University Medical Center, Durham, NC (United States)

    2010-12-15

    The purpose of this study was to determine the incidence of meniscal cysts, assess the frequency of various magnetic resonance (MR) imaging characteristics, and emphasize radiographic observations not commonly reported. A total of 2,095 consecutive knee MR imaging reports from a 22 month period were retrospectively reviewed for the presence of meniscal cysts. Two musculoskeletal radiologists reviewed the cases where cysts were reported. A meniscal cyst was considered present if abnormally increased signal was identified within an enlarged meniscus (i.e., intrameniscal cyst) or if a loculated fluid-intensity lesion with a clear connection to the adjacent meniscus was identified (i.e., parameniscal cyst). Presence or absence of a meniscal tear, intrameniscal and parameniscal signal intensity, patient age, sex, location of meniscal cyst, presence of discoid meniscus, and size of the parameniscal cyst component were recorded. All knee imaging examinations were performed on a 1.5T MR unit. Imaging findings were correlated with arthroscopic reports when available. A total of 167 cases (8.0%) of meniscal cysts were diagnosed in 161 patients. Of the 167 cysts, 69 (41.3%) were located in the lateral meniscus and 98 (58.7%) in the medial meniscus. In 6 patients (3.7%), meniscal cysts were present in both menisci of the same knee. Twelve (7.2%) meniscal cysts were associated with discoid menisci. Ninety-seven (57.8%) meniscal cysts were associated with meniscal tears. Of the total number of meniscal cysts, 104 (62.3%) had a parameniscal cyst. An isolated intrameniscal cyst was present in 63 (37.7%) cases. One hundred (96%) of the parameniscal cyst components were isointense to fluid on T2-weighted FSE images. All cysts exhibited abnormal intrameniscal signal. Only 14 (8.4%) of the intrameniscal components were isointense to fluid on T2-weighted FSE images. The arthroscopic reports of 88 of the 161 (54.7%) patients were available for review and correlation. A tear extending to

    Neurenteric cysts are extremely rare congenital anomalies, often presenting in the first 5 years of life, and are caused by an incomplete separation of the notochord from the foregut during the third week of embryogenesis. They are frequently accompanied with spinal or gastrointestinal abnormalities, but the latter may be absent in adults. Although usually located in the thorax, neurenteric cysts may be found along the entire spine. We present a 24-year-old woman admitted for epigastric pain, nausea, vomiting, low grade fever and leucocytosis. She underwent cystgastrostomy for a loculated cyst of the distal pancreas at the age of 4 years, which recurred when she was at the age of 11 years. Ultrasound and computer tomograghy (CT) scan revealed a 16cm×15cm cystic mass in the body and tail of pancreas, with a 6-7 mm thickened wall. Laboratory data and chest X-ray were normal and spinal radiographs did not show any structural abnormalities. The patient underwent a complete cyst excision, and after an uneventful recovery, remained symptom-free without recurrence during the 5-year follow-up. The cyst was found to contain 1200mL of pale viscous fluid. It was covered by a primitive singlelayered cuboidal epithelium, along with specialized antral glandular parenchyma and hypoplastic primitive gastric mucosa. Focal glandular groups resembling those of the body of the stomach were also seen. In addition, ciliary respiratory epithelium, foci of squamous metaplasia and mucinous glands were present. The wall of the cyst contained a muscular layer, neuroglial tissue with plexogenic nerve fascicles, Paccini corpuscle-like structures, hyperplastic neuroganglionar elements and occasional psammomatous bodies, as well as fibroblast-like areas of surrounding stroma. Cartilagenous tissue was not found in any part of the cyst. Immunohistochemistry confirmed the presence of neurogenic elements marked by S-100, GFAP, NF and NSE. The gastric epithelium showed mostly CK7 and EMA

    Full Text Available The calcifying odontogenic cyst (COC is reported to be associated with odontoma in 24% of cases. Separation of the cases of calcifying odontogenic cyst associated with odontoma (COCaO may lead to a better understanding of the pathogenesis of this lesion. The literature revealed 52 cases of COCaO. The male to female ratio was 1:1.9, with a mean age of 16 years. Most common location was the maxilla (61.5%. The radiographic appearance of most cases (80.5% was a well-defined, mixed radiolucent-radiopaque lesion. Histologically, the lesions consisted of a single large cyst with tooth-like structures as an integral part, giving the impression of a single lesion. In addition to the unique histologic features, differences in gender and distribution were found between the cases of COCaO and those of simple COC. COCaO may be regarded as a separate entity and classified as a benign, mixed odontogenic tumor. The term odontocalcifying odontogenic cyst is suggested.

    Sacral perineurial (Tarlov) cysts are rare lesions. Over a seven year period 4000 patients underwent surgery for lumbar disk herniation. In three patients neurological symptoms were caused by large sacral perineurial cysts. Methods of choice for diagnosis of Tarlov cysts are lumbosacral magnetic resonance imaging and computerized tomography myelography. The majority of Tarlov cysts are asymptomatic. In case of large (> or = 1.5 cm) and symptomatic perineurial cyst, as in three patients reported in this article, microsurgical treatment was successful. Although rare, perineurial (Tarlov) cysts must be taken into consideration when approaching to patient with low back and radicular pain. Authors review the medical literature, pathological and pathophysiological features and treatment options of sacral perineurial cysts.

  12. [Arachnoid cysts: Embriology and pathology].

    Science.gov (United States)

    García-Conde, Mario; Martín-Viota, Lucia

    2015-01-01

    There is still great controversy surrounding the origin of the arachnoid cyst. The most accepted theory in the case of congenital cysts explains how they are formed from an anomalous development of the arachnoid membrane, which is unfolded allowing the accumulation of cerebrospinal fluid inside and creating a cyst. This theory seems to explain the origin of convexity and sylvian cistern arachnoid cysts, whereas those in other locations might be due to other mechanisms. In the anatomopathological analysis, the arachnoid cyst wall can be seen as having few differences from normal, although thickened due to an increase quantity of collagenous material. A description of the embryological development of the arachnoid layer and cyst formation is presented, describing the main anatomopathological findings.

These are usually located within the pancreas but they can occur at other sites as well, including the mediastinum, neck, pelvis and rarely in the liver as in our case. The diagnosis of intrahepatic pancreatic pseudocyst relies on the demonstration of a high amylase level in the sampled cystic fluid in the absence of infection or neoplasm. Case report A 60-year-old man with a history of chronic pancreatitis presents with a clinical and laboratory picture suggestive of acute exacerbation of his pancreatitis. A computed tomogram (CT scan of the abdomen revealed a pancreatic pseudocyst and a cystic lesion involving both lobes of the liver. CT diagnostic aspiration of the intrahepatic cyst revealed high amylase level (greater than 20,000 U/L. The cyst was treated with percutaneous drainage with complete resolution of the cyst. Conclusion In the setting of pancreatitis, intrahepatic pancreatic pseudocyst should be considered in the differential diagnosis of cystic lesion of the liver.

  8. Neurenteric cysts of the spine

    Directory of Open Access Journals (Sweden)

    J J Savage

    2010-01-01

    Full Text Available Neurenteric cysts account for 0.7-1.3% of spinal axis tumors. These rare lesions result from the inappropriate partitioning of the embryonic notochordal plate and presumptive endoderm during the third week of human development. Heterotopic rests of epithelium reminiscent of gastrointestinal and respiratory tissue lead to eventual formation of compressive cystic lesions of the pediatric and adult spine. Histopathological analysis of neurenteric tissue reveals a highly characteristic structure of columnar or cuboidal epithelium with or without cilia and mucus globules. Patients with symptomatic neurenteric cysts typically present in the second and third decades of life with size-dependent myelopathic and/or radicular signs. Magnetic resonance imaging and computed tomography are essential diagnostic tools for the delineation of cyst form and overlying osseous architecture. A variety of approaches have been employed in the treatment of neurenteric cysts each with a goal of total surgical resection. Although long-term outcome analyses are limited, data available indicate that surgical intervention in the case of neurenteric cysts results in a high frequency of resolution of neurological deficit with minimal morbidity. However, recurrence rates as high as 37% have been reported with incomplete resection secondary to factors such as cyst adhesion to surrounding structure and unclear dissection planes. Here we present a systematic review of English language literature from January 1966 to December 2009 utilizing MEDLINE with the following search terminology: neurenteric cyst, enterogenous cyst, spinal cord tumor, spinal dysraphism, intraspinal cyst, intramedullary cyst, and intradural cyst. In addition, the references of publications returned from the MEDLINE search criteria were surveyed in order to examine other pertinent reports.

    Full Text Available Hydatid disease is caused by the tapeworm Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis . Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease occurs either through direct ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%, followed by the lungs (18-35%. Bone hydatidosis however is very rare (3%. We present herein a case of hydatid cyst of the fibula, which is an uncommon site for the occurrence of this disease.

  13. Simple cyst of urinary bladder.

    2014-07-01

    Simple cysts are rare in the urinary bladder and can pose a diagnostic dilemma to both the urologist and the histopathologist. No case study was found in the database of Elsevier Science Direct, Spring-Link, or PubMed. We present two cases of subserous cyst in the bladder and discuss the diagnosis and treatment of the condition. The cystic lesion at bladder dome was detected by radiologic examination and confirmed by cystoscopy. In case 1, transurethral resection was first performed which was followed by partial cystectomy; In case 2, the cyst was removed with the urachus using laparoscopic surgery. The patients recovered uneventfully and the histopathology showed cysts in subserous layer of urinary bladder. The bladder cyst should be distinguished from urachal tumor, and laparoscopic partial cystectomy is the preferred operative procedure.

    Carlos Eduardo Molinari Nardi

    Full Text Available CONTEXT: Parathyroid cysts are rare clinical and pathological entities, with less than 300 cases reported. The inferior parathyroid glands are most commonly involved, with left-side predominance. Parathyroid cysts may be functional or nonfunctional, depending on their association with hypercalcemia. CASE REPORT: A 25-year-old man presented a palpable asymptomatic left-side neck mass. Ultrasound revealed a cystic structure contiguous with the left thyroid lobe. Serum ionic calcium was normal. The patient underwent left thyroid lobectomy plus isthmectomy with excision of the cyst. The histological findings revealed a parathyroid cyst. Parathyroid cysts typically present as asymptomatic neck masses, and surgical excision appears to be the treatment of choice.

    Full Text Available The paraurethral or Skene’s duct cyst, is a rare diagnostic entity in a newborn. It represents less than 0,5 % of congenital malformations of the urinary tract. All over the world it is reported an incidence of 1:2000 to 1:7000 in female births. In the newborn, the paraurethral cyst is caused by retention of secretions in the Skene's gland due to the obstruction of its ducts. Most of these cysts decrease in size during the first four to eight weeks, but they may cause symptoms of infection or urinary obstruction. They can also get formed from persistent embryonic remains of the mesonephric ducts (Wolffian duct, known as Gartner cysts and from the occlusion of unfused paramesonephric ducts (Müllerian. The case of a 25-day-old female, diagnosed with paraurethral cyst that underwent surgery and evolved successfully is presented.

    Background Echinococcosis is still endemic in many countries, including China, where it is especially prevalent in the northwest. The aim of this study was to enrich the international literature about the treatment of intracranial hydatid cysts.Methods We retrospectively reviewed the clinical features, radiological manifestations, and surgical outcome of 97 patients with intracranial hydatid cysts, who received surgical treatment at the Neurosurgical Department of First Affiliated Hospital of Xinjiang Medical University from 1985 to 2010 and followed up the patient via sending a questionnaire or telephone contact. Clinical outcome was evaluated using the Karnofsky Performance Scale Index.Results Headache and vomiting were the most common initial symptoms in our patients. Neurological deficits caused by the mass effect of the cysts were seen in 82 cases. On the X-ray, significant bone erosion was seen in only two cases with epidural hydatid cysts. Round-shaped and thin-walled homogeneous low-density cystic lesions without surrounding edema and enhancement were the main findings on computerized tomography (CT) in 95 patients with intraparenchymal hydatid cysts, while two cases with epidural hydatid cysts presented as a heterodensity lesions. On magnetic resonance imaging (MRI), hydatid cyst presented as a round-shaped low signal lesion in T1-weighted images and high signal lesion in T2-weighted images, without enhancement after contrast media injection, while the two cases with epidural cysts presented as mixed signal masses. Surgical removal of cyst was performed in all cases. Total removal was achieved in 93 cases without rupturing the cyst wall. Only two cysts ruptured during the dissection, resulting in two surgery-related mortalities. There was no other additional neurological deficit caused directly by surgery. In 97.2% of the patients, the Karnofsky Performance Scale score was 80 to 90 at the last follow-up.Conclusions Intracranial hydatid cyst is still a

    Epidermal cysts also known as epidermoid cysts, is one of the common benign tumours presenting anywhere in the body. However, epidermal cyst in the penis is very rare. This condition in children is usually congenital due to abnormal embryologic closure of the median raphe; hence, it is termed as median raphe cysts (MRCs). Penile epidermal cysts may occur in adults following trauma or surgery due to epidermal elements being trapped within closed space. During wound healing, trapped squamous epithelium, undergoing keratinisation leads to cyst formation. Here, we report a rare case of patient with a penile epidermoid cyst whose main complaints was discomfort during coitus. PMID:27437298

    In Western Siberia (Russia) there are about 100 Artemia lakes with total area over 1 600 km2. Geographically these lakes are located between 51°-56°N and 61°-82°E. In general these lakes are shallow (depth less than 1.5 m), small or medium size (0.1 to 10 km2); they are chloride; their total salinity is from 40 to 250 g/L. The harvesting of cysts per year is only in 20-40 lakes. In Russia 550 tons of dry Artemia cysts (14%-18% of the world production) were harvested annually. This includes about 350 tons in the Altai region and 200 tons in other regions. During our regular 20-year study period the cyst harvest was: 95 tons in Kurgan; 65 tons in Omsk, 20 tons in Novosibirsk, 20 tons in Tyumen. Ways of increasing cyst harvest in Russia are considered in this article. During the last 30 years the harvest of cysts in Russia has increased from 7-20 to 500-600 tons. A significant influence of dryness of the year was found on productivity in selected lakes, but taken for all the lakes together, the relationship was not significant. The optimal salinity for productivity of cysts in the lakes was determined. Analysis of productivity of the lakes and the harvesting results showed that the stocks of cysts are underutilized by approximately 1.7 times.

    A 52 year-old construction worker presented with progressive painful blurring of vision in the left eye associated with redness for past 1 month. There was a history of penetrating injury in the same eye 10 years ago and he underwent primary wound toilet and suturing, lens removal with intraocular lens implantation. Slit lamp examination revealed a corneal scar at 9’oclock, a large transilluminant iris cyst superotemporally and adherent to corneal endothelium. It was extended from angle of the pupil and obstructing the visual axis. The patient underwent excision of an iris cyst through superior limbal incision. Viscodissection was done to separate the cyst from the corneal endothelium and underlying iris stroma. Trypan blue ophthalmic solution was injected into the cyst to stain the cyst capsule. Post operatively 7 days, vision improved to 6/7.5 without complication. There was no recurrence up to 1 year postoperation. Histopathological finding revealed a benign cyst mass lined by simple cuboidal to non-keratinized stratified squamous epithelium. We had achieved a good surgical outcome with no complication to date for our case study. We advocate this modified surgical method to completely remove iris cyst.

    The preoperative diagnosis of intracranial arachnoid cysts has been simplified, and made more rapid and accurate with computed tomography (CT). Using CT cisternography, detailed anatomic and physiologic information of arachnoid cysts could be obtained. CT features of pathologically proven 21 arachnoid cysts that were examined at Chonnam National University Hospital from June 1983 to May 1987 were analyzed. The results were as follows: 1.Prevalent age group was the 1st decade (8 cases) and male to female ratio was 17:4. 2.Clinical features were related to the location of arachnoid cyst, common symptoms were headache (53.3%), convulsion, mental change and walking disturbance. 3.Location of the arachnoid cyst were in supratentorial region (15 cases) most in middle cranial fossa (12 cases), and infratentorial region (6 cases), common at the retrocerebellar cisternal space (3 cases). 4.Shapes of arachnoid cyst were biconvex with straight inner margin (8 cases), spherical (7 cases), simple biconvex (3 cases) and others (3 cases). 5.Size of the arachnoid cyst, in the greatest dimension, was ranged from 2cm to 9cm and commonly distributed between 3cm to 5cm (14 cases). 6.Of all 14 cases, who did CT cisternography using metrizamide (11 cases) and iopamidol (3 cases), 2 cases had communication with the subarachnoid space.

    To evaluate the incidence and characteristic findings of pineal cyst incidentally detected on magnetic resonance (MR) imaging. Brain MR images obtained in 2432 patients were retrospectively reviewed to determine the incidence and MR findings of pineal cysts, which were evaluated according to their size, shape, location, signal intensity, interval change, contrast enhancement and mass effect on adjacent structures. Cysts were encountered in 107(4.4 %) of 2432 patients evaluated. their size ranged from 1 X 1 X 1 to 15 X 8 X 9 (mean, 5.97 X 3.82 X 4.82)mm. All were spherical (n=53) or oval (n=54) in shape. Their margin was smooth and they were homogeneous in nature. On T1-weighted images, the cysts were seen to be hyperintense (n=57) or isointense (n=50) to cerebrospinal fluid, but less so than brain parenchyma. T2-weighted images showed them to be isointense (n=51)or hyperintense (n=56) to cerebrospinal fluid. The cysts were centrally located in 65 cases and eccentrically in 42. Compression of the superior colliculi of the tectum was demonstrated in 17 cases (15.9 %). NO patients presented clinical symptoms or signs related to either pineal or tectal lesions. Peripheral enhancement around the cyst after Gd-DTPA injection was demonstrated in 51 cases(100 %). Follow-up examinations in 19 cases demonstrated no interval change. The incidence of pineal cysts was 4.4 %. The MR characteristics of simple pineal cysts include: (1) an oval or spherical shape, (2) a smooth outer margin and homogeneous nature, (3) isosignal or slightly high signal intensity to cerebrospinal fluid on whole pulse sequences, (4) ring enhancement after contrast injection, (5) an absence of interval change, as seen during follow up MR study. These MR appearances of pineal cysts might be helpful for differentiating them from pineal tumors.

    Objective: Ovarian cysts are the most frequently encountered intra-abdominal masses in females in utero. They may, at times, require perinatal intervention. Using magnetic resonance imaging (MRI) as an adjunct to ultrasonography (US) in prenatal diagnosis, we sought to demonstrate the ability to visualize ovarian cysts on prenatal MRI. Materials and methods: This retrospective study included 17 fetal MRI scans from 16 female fetuses (23-37 gestational weeks) with an MRI diagnosis of ovarian cysts after suspicious US findings. A multiplanar MRI protocol was applied to image and to characterize the cysts. The US and MRI findings were compared, and the prenatal findings were compared with postnatal imaging findings or histopathology. Results: Simple ovarian cysts were found in 10/16 cases and complex cysts in 7/16 cases, including one case with both. In 11/16 (69%) cases, US and MRI diagnoses were in agreement, and, in 5/16 (31%) cases, MRI specified or expanded the US diagnosis. In 6/16 cases, postnatal US showed that the cysts spontaneously resolved or decreased in size, and in 1/16 cases, postnatal imaging confirmed a hemorrhagic cyst. In 4/16 cases, the prenatal diagnoses were confirmed by surgery/histopathology, and for the rest, postnatal correlation was not available. Conclusion: Our results illustrate the MRI visualization of ovarian cysts in utero. In most cases, MRI will confirm the US diagnosis. In certain cases, MRI may provide further diagnostic information, additional to US, which is the standard technique for diagnosis, monitoring, and treatment planning.

    Full Text Available Paradental cy st is an inflammatory odontogenic cyst arising in association with partially erupted third molars affected with pericoronitis. The common location is on the buccal aspect of the molar teeth. Radiographically, the characteristic presen­ tation is a well defined radiolucency superimposed on the roots. Histologically, cysts were lined with nonkeratinized epithelium. The various concepts underlining the origin/pathogenesis of this rare entity is discussed and critically apprised.

    2016-06-01

    Full Text Available The urachus is an embryological tubular structure extending from the umbilicus to the urinary bladder apex, which usually gets obliterated but may persist uncommonly in adults. Rarely, the urachus may be the primary site of benign and malignant neoplasms. Urachal malignancies are rare and represents less than 1% of all bladder neoplasms. CASE REPORT A 39-year-old female presented with pain and lump in the lower abdomen for 6 months’ duration. No other symptoms. History of caesarean section 8 years back. On examination, a lower midline scar present. A vague swelling of size 6 x 5 cm present in the left lower abdomen adjacent to scar, surface smooth, firm, non-tender and non-reducible. Provisional diagnosed as irreducible, nonobstructing incisional hernia. Routine investigations were normal. Ultrasonogram abdomen was equivocal. CT abdomen plain and oral contrast confirmed a urachal cyst with subcutaneous component, so we planned for diagnostic laparoscopy and exploration. Intra-operatively, a 4x4 cm midline cystic mass infra-umbilical, well away from bladder dome. Abdominal component was mobilized laparoscopically using monopolar hook. A connecting component was identified entering the linea alba close to umbilicus into subcutaneous plane. Further laparoscopic dissection abandoned. A small mid-midline incision was made and both components excised in-toto. The final histopathology report came as fibrocollagenous, fibromyxoid, fibrofatty cyst wall lined by cuboidal to polygonal epithelial cells with focal atypia. Features consistent with urachal cystadenoma with focal atypia. CONCLUSION Rarely described in literature, it should be treated as mucinous cystadenoma of undetermined malignant potential which has the tendency for local recurrence should be completely excised. Followup of these tumours is mandatory, as it presents with focal atypia

    DEFF Research Database (Denmark)

    Bruus, Marianne; Dupont, Yoko Luise; Grant, Ruth;

    Både i Danmark og andre steder er der observeret en nedgang i de insekter, der bestøver landmandens afgrøder og de vilde planter. Tilbagegangen falder sammen med, at landbrugsdriften er blevet mere intensiv, og anvendelsen af pesticider er øget. Vi ved imidlertid ikke, hvilken rolle pesticiderne...... vigtige for bestøvningen af fx kløver og mange vilde planter. Da humlebier og andre vilde bier har en anden adfærd og placerer deres reder andre steder end honningbierne, er det ikke givet, at de er beskyttet mod pesticideksponering, selv om honningbierne er. I pilotprojektet ”Betydningen af pesticider...... for forekomsten af vilde bier og honningbier” har Aarhus Universitet på to landbrugsbedrifter gennemført en indledende undersøgelse af, om humlebier udsættes for pesticider i danske landbrugsområder.

    Maxillary cysts are a diverse group of entities that include benign and malignant odontogenic tumors. Information on the prevalence of this disease is limited. It is more common among males, and usually occurs in the second and third decade of life. The proportion of 6 to 7 year old patients with dentigerous cysts is only 9.1%. Dentigerous cysts encompass the crown of a permanent and unerupted impacted teeth. They are usually slow growing asymptomatic lesions that are not discovered until they affect surrounding organs. The aim of this study is to present an unusual case of dentigerous cyst and to inform the pediatrician about the management of a unilateral maxillary tumor in a healthy child, underlining the importance of a multidisciplinary approach of this disease.

    Full Text Available Epidermoid cysts are benign slow growing more often extra-axial tumors that insinuate between brain structures, we present the clinical, imaging, and pathological findings in 35 years old female patients with atypical epidermoid cysts which was situated anterior, middle & posterior cranial fossa. NCCT head revealed hypodense lesion over right temporal and perisylvian region with extension in prepontine cistern with mass effect & midline shift and MRI findings revealed a non-enhancing heterogeneous signal intensity cystic lesion in right frontal & temporal region extending into prepontine cistern with restricted diffusion. Patient was detoriated in night of same day of admission, emergency Fronto-temporal craniotomy with anterior peterousectomy and subtotal resection was done. The histological examination confirms the epidermoid cyst. The timing of ectodermal tissue sequestration during fetal development may account for the occurrence of atypical epidermoid cysts.

    Full Text Available A case of hydatid cyst of the tibia, which manifested as a pathologic fracture is being reported. Pain and swelling of left lower limb with inability to bear the weight were the main features. Tender swelling was also noted at the upper and middle third of tibia.

    2009-03-01

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    2014-01-01

    Purpose This is a clinco-histopathological study of different varieties of conjunctival cysts where modification of surgical technique was done as per requirement for intact removal of cysts to minimise recurrence rate. Materials and methods Retrospective study of 40 cases of conjunctival cysts. A thorough ocular examination and basic haematological work up was done for all patients. B-scan USG and MRI was done wherever required to see the posterior extent. All patients underwent surgical excision of cyst followed by histo-pathological examination. Results The various types of conjunctival cysts found in our study were primary inclusion cyst 12 (30%), secondary inclusion cyst 6 (15%), pterygium with cysts 15 (37.5%), parasitic cyst 4 (10%), lymphatic cyst 2 (5%), and orbital cyst with rudimentary eye 1 (2.5%). The common symptoms noted were progressive increase in size of cyst (39.45%), cosmetic disfigurement (26.23%), foreign body sensations (27.86%), proptosis (1.6%), ocular motility restrictions (3.2%) and decreased visual acuity (1.6%). The patients were followed till one year after surgical excision for any recurrence and complications and no recurrence was seen. Conclusion Careful and intact removal of conjunctival cyst is important to prevent recurrence. Minor modifications in surgical technique according to the size, site and nature of cyst help in intact removal and prevent recurrence. PMID:25892928

    Wagner, Michael

    Det amerikanske automobilfirma Ford Motor Company med hovedkvarter i Detroit begyndte at drive forretning i Danmark omkring 1906. De første aktiviteter blev konsolideret samme år ved udnævnelsen af motorforhandleren F. Bülow & Co. til salgsagent i Danmark og importør af Ford automobiler til det...... skandinaviske marked. Dermed havde Ford tidligt fået et stærkt fodfæste i Nordeuropa, som udviklingen i salget af Ford autobiler de næste årtier til fulde skulle demonstrere. Ford Motor Company er i dag den fjerde største bilproducent på verdensmarkedet, men går man tilbage til 1920'rne var selskabet førende...... med en markedsandel på mere end 50%. En position som Ford måtte afgive til General Motors i løbet af årtiet. I Danmark var mere end hvert andet indregistreret automobil i 1930 antageligt af mærket Ford, og helt frem til verdenskrigens udbrud var Ford Motor Company et brand, som spillede en meget...

    Paraurethral or Skene's duct cysts are rare causes of interlabial masses in neonates. The diagnosis of Skene's duct cysts in the neonatal period is based on its location, in relation to the urethra, and the demonstration of transitional epithelium in the cyst wall. The distinguishing features of paraurethral cysts are the displacement of urethral meatus by the mass and a cyst containing milky fluid. Thus, we report a case of a Skene's duct cyst in a newborn which was treated by incision and drainage. PMID:24049387

    1984-06-01

    Anamnesis and treatment of two cases of arachnoid cysts extending into the subarachnoid space are described. No traumatic incident was discovered in the previous history of these two patients. The causal genesis of neurological signs of deficiency in patients with arachnoid and acquired cysts is discussed. However, the cause of the development of a subdural hygroma in arachnoid cysts remains unclarified. CT findings of arachnoid cysts with a hypodense zone between brain surface and the vault of the cranium always require an investigation into the possibility of a spontaneous emptying of the cyst or of a congenital and not only localised extension of the cyst itself.

    2013-07-01

    Full Text Available Introduction: Dermoid cysts are congenital tumors caused by entrapment of ectoderm during embryogenesis. The most common localization are the gonads and less than 10% are in the head and neck. They are slow growing and generally observed between the second and third decades of life, being unusual in chilhood. Description: We report a case of a 5 year old male with recurrent respiratory infections, mouth breathing and snoring with apneas and daytime sleepiness. On physical examination tonsillar hypertrophy and a 4 cm sublingual tumor are detected. As complementary tests are performed overnight polysomnography with AHI of 18.3 / h and ultrasonography, reported as cystic mass with multiple rounded echogenic structures inside. Results: The patient was diagnosed with severe OSA and tonsillectomy and intraorally enucleation of tumor (as diagnosis and treatment were performed; with histopathological diagnosis of dermoid cyst. In the postoperative control we check the resolution of respiratory events and snoring. Discussion: Dermoid cysts of the oral cavity (where sublingual localization is the most common represent only 0,01% of all cysts and 1,6% of all dermoid cysts. Usually present as slow-growing asymptomatic mass, even if they reach large size can compromise swallowing, speech or breathing and eventually cause, as in our case, a severe OSA. The surgical treatment allows to confirm the diagnosis an avoid the risk of infectious complications and eventual malignant transformation.

    2007-08-01

    Perineural cysts have become a common incidental finding during lumbosacral magnetic resonance (MR) imaging. Only some of the symptomatic cysts warrant treatment. The authors describe the successful operative treatment of a patient with, to the best of their knowledge, the largest perineural cyst reported to date. A 29-year-old woman had been suffering from long-standing constipation and low-back pain. During an obstetric investigation for infertility, the clinician discovered a huge presacral cystic mass. Computed tomography myelography showed the lesion to be a huge Tarlov cyst arising from the left S-3 nerve root and compressing the ipsilateral S-2 nerve. The cyst was successfully treated by ligation of the cyst neck together with sectioning of the S-3 nerve root. Postoperative improvement in her symptoms and MR imaging findings were noted. Identification of the nerve root involved by the cyst wall, operative indication, operative procedure, and treatment of multiple cysts are important preoperative considerations.

    Goh, Rachel L Z; Hardy, Thomas G; Williams, Richard A; McNab, Alan A

    2016-10-01

    To describe post-traumatic and congenital respiratory epithelial cysts in the orbit, which are rare lesions with only 5 and 13 published cases, respectively. We reviewed all cases of respiratory epithelial cysts diagnosed at three institutions (two tertiary referral hospitals, one private clinic) between 1995 and 2015. We describe 10 cases of post-traumatic respiratory epithelial cyst (age range 23 - 82), presenting a mean of 17.4 years after their original trauma; and 3 congenital cases (age range 17-34). All but one case underwent surgical excision of the cyst and its lining, along with any surgical implant within the cyst. Two were recurrent after incomplete excision. Three presented with acute infection within the cyst. Respiratory epithelial orbital cysts are probably commoner than the paucity of published reports would suggest. Post-traumatic cysts often present many years after trauma, and may become secondarily infected. Complete surgical removal is recommended to prevent future recurrence.

    1995-01-01

    Between 1974 and 1993, 22 patients with bronchogenic cysts were operated on in our hospital; there were 14 men and 8 women, ranging in age from 11 to 62 years, The cyst locations were mediastinal in 13 (59.1%) and intrapulmonary in 9 (40.9%). There were symptoms (chest pain and recurrent bronehiolits) in 20 patients (91%). The preoperative complications included infection in the lung and in the cyst and dysphagia due to esophageal eornpression. Chest pain was the main symptom in mediastinal cyst and recurrent infection of lung in intrapulmonary cyst. Plain chest radiograms showed that a rousd shadow, occasional air-fluid levels, and peripheral calcification may be found in cysts. An operation is the best treatment for cysts. All cysts were completely excised. No postoperative complieations, late complica-tions, or recurrence developed in our patients.

    Første gang sammenhængen mellem caries (huller i tænderne) og fluoridindholdet i drikkevand blev diskuteret i vandværkskredse i Danmark var ved årsmødet i 1958. Her blev det oplyst, at fluorid i drikkevand beskytter mod caries, men man konstaterede også, at der nok ikke var stemning for fluorid......-tilsætning til drikkevandet (fluoridering). Siden da er emnet ikke taget op. Formålet med dette indlæg er at besvare spørgsmålene: 1. Er der behov for fluoridering af drikkevandet i Danmark? 2. Er der alternativer? Hvordan påvirker blødgøring af vand og andre vandbehandlingsmetoder dental caries hos børn og unge......? Som baggrund herfor vil vi redegøre for resultaterne af et netop afsluttet studium af sammenhængen mellem caries og drikkevandets sammensætning, specielt m.h.t. luoridindholdet og vandets calciumindhold (hårdhed).

    Most of Tarlov or perineurial cysts remain asymptomatic throughout the patient's life. The pathogenesis is still unclear. Hemorrhage has been suggested as one of the possible causes and trauma with resultant hemorrhage into subarachnoid space has been suggested as an origin of these cysts. However, Tarlov cysts related to spontaneous subarachnoid hemorrhage has not been reported. The authors report a case of Tarlov cyst which was symptomatic following spontaneous subarachnoid hemorrhage.

    Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomograghy (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space.

    Full Text Available Arachnoid cysts are rare, usually benign, space-occupying central nervous system lesion. They are the results of an accumulation of cerebrospinal-like fluid between the cerebral meninges and diagnosed prenatally as a unilocular, simple, echolucent area within the fetal head. They may be primary (congenital (maldevelopment of the meninges or secondary (acquired (result of infection trauma, or hemorrhage. The primary ones typically dont communicate with the subarachnoid space whereas acquired forms usually communicate. In recent years, with the development of radiological techniques, the clinical detectability of arachnoid cysts seems to have increased. We report a case of primary arachnoid cyst that were diagnosed prenatally by using ultrasonography and magnetic resonance imaging . [Cukurova Med J 2016; 41(4.000: 792-795

    Objective. To evaluate the surgery in simple ovarian cysts.Methods. From Jan. 1994 to Dec. 1999, 221 women with simple ovarian cysts were admitted into ourhospital. The diameter of cysts was <5 cm in 76 cases, and was≥5 cm in 145 cases ultrasonically.One hundred and eighty-four patients underwent laparosocopy, and thirty-seven underwent laparotomy.Results. Histological findings showed no malignancy in this series. Simple cysts, paraovarian cystsand corpus luteum were found histologically in 90.8% of cases with cysts <5 cm, and 60% of those withcysts >7 cm respectively, their difference was significant (X2=-37.13, P<0.001). The simple cysts, paraovar-ian cysts and corpus luteum cysts were found in 81.5% of postmenopausal women and 84.0% of pre-menopausal women. Conclusion. Patients with cysts >7 cm are indicated for surgical procedures, while a period of fol-lowup is acceptable for patients with cysts <7 cm, and surgery is advisable if the cyst is persistent dur-ing followup. Postmenopausal women with cysts should have operations.

    Mediastinal parathyroid cysts are very rare. Since the first report by DeQuervain, 19 cases have been reported. We encountered a case of mediastinal parathyroid cyst presenting as displacement of the trachea. The cyst originated in the lower portion of the left lobe of the thyroid gland and extended to the mediastinum, displacing the trachea and the esophagus. The monolocular mass was a thin walled cyst, and mognetic imaging indicated that it contained watery fluid. The left lobe of the thyroid gland was found to be displaced upward by the tumor, on thyroid scintigram done with technetium-99, which suggested that the cyst originated in the parathyroid gland.

    Full Text Available Epidermoid cysts are common cystic lesions in the skin, ovaries, and testicles, but their occurrence in the oral cavity is uncommon. They consist of cysts delimited by a fibrous capsule without cutaneous annexes and are lined by stratified squamous epithelium. The differential diagnosis includes ranula, dermoid cysts, and lingual thyroid. Despite their benign presentation, these cysts can cause functional limitations, requiring special clinical attention for extensive lesions located in regions that preserve vital structures. This paper aims to report a case of epidermoid cyst in patient with swallowing and breathing difficulty, highlighting the clinical and surgical planning.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion and are usually asymptomatic. Symptomatic sacral perineural cysts are uncommon but sometimes require surgical treatment. A 69-year-old male presented with pain in the buttock. He was diagnosed as having a sacral cyst with magnetic resonance imaging. For the nonoperative diagnosis and treatment, caudal peridurography and block were performed. After the treatment, the patient's symptom was relieved. We suggest a caudal peridural block is effective in relieving pain from a sacral cyst.

    Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used.

  10. New insights about suprapatellar cyst

    Directory of Open Access Journals (Sweden)

    Tomislav Crnkovic

    2012-02-01

    Full Text Available bursa is located between the quadriceps tendon and femur, and it develops before the birth as a separate synovial compartment proximal to the knee joint. By the fifth month of fetal life there is a suprapatellar septum between the knee joint cavity and suprapatellar bursa which later perforates and involutes in a way that a normal communication between the cavity of bursa and knee is established. A small portion of the embrionic septum can later lag as more or less expressed suprapatellar plica. In case when suprapatellar plica has a small communication with valve mechanism or in case of complete septum, bursa becomes a separate compartment and potential location for the suprapatellar cyst development. Magnetic resonance imaging is recognised as the gold standard in diagnosis of knee cysts because of its ability to show cystic nature of the lesion, its relationship with other anatomic structures, as well as to establish whether other knee pathologies are present. Considering treatment possibilities, majority of cysts around the knee resolve spontaneously and should be treated by aspiration and application of corticosteroids. Suprapatellar cyst is a very rare knee pathology and it can in some occasions be treated using open or arthroscopic surgery.

  11. Symptomatic Tarlov cyst: report and review.

    Tarlov or perineural cysts are nerve root cysts found most commonly at the sacral spine level arising between covering layers of the perineurium and the endoneurium near the dorsal root ganglion. The cysts are relatively rare and most of them are asymptomatic. Some Tarlov cysts can exert pressure on nerve elements resulting in pain, radiculopathy and even multiple radiculopathy of cauda equina. There is no consensus on the appropriate therapeutic options of Tarlov cysts. The authors present a case of two sacral cysts diagnosed with magnetic resonance imaging. The initial symptoms were low back pain and sciatica and progressed to cauda equina syndrome. Surgical treatment was performed by sacral laminectomy and wide cyst fenestration. The neurological deficits were recovered and had not recurred after a follow-up period of nine months. The literature was reviewed and discussed. This is the first reported case in Thailand.

  20. Congenital cervical bronchogenic cyst: A case report

    Directory of Open Access Journals (Sweden)

    Kiralj Aleksandar

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Hydatid disease is a zoonosis that can involve almost any organ in the human body. After the liver, the lungs are the most common site for hydatid disease in adults. Imaging plays a pivotal role in the diagnosis of the disease, as clinical features are often nonspecific. Classical radiological signs of pulmonary hydatid cysts have been described in the literature, aiding in the diagnosis of the disease. However, complicated hydatid cysts can prove to be a diagnostic challenge at times due to their atypical imaging features. Radiography is the initial imaging modality. Computed tomography can provide a specific diagnosis in complicated cases. Ultrasound is particularly useful in peripheral lung lesions. The role of magnetic resonance imaging largely remains unexplored.

    Full Text Available Intraosseous ganglia are benign cysts that usually can be seen in lower extremity; especially around ankle. These cysts have fewer incidences in upper extremity, mainly around the wrist. They are extremely rare in olecranon. These lesions are often asymptomatic. Patient was a 75-year-old man who had trauma many years ago. When he came to our clinic, he complained of severe pain around his elbow that he could not do ordinary activity. He had local tenderness in elbow and 30 degree limitation in extension. In radiography, lytic, multiloculated lesion existed in region of olecranon. After excisional biopsy was done, cavity was cleaned completely with curette and was filled with autogenous bone. At 10-year follow-up, the patient was completely asymptomatic. Control radiograph showed cavity filled completely by bone; there was no evidence of relapse.

    Full Text Available In the oro-facial region cystic lesions of different etiologies are encountered owing to the presence of the teeth in the jaw bones. A bewildering variety of developmental, odontogenic and non-odontogenic cysts are seen. Epidermoid cyst is a rare developmental cyst of the oro-facial region which results from entrapped epidermal elements without adnexal appendages. Dermoid and epidermoid cysts occur in oro-facial region with an incidence of 6.9-7% and represents less than 0.01% of all oral cavity cysts. Here we report two cases of epidermoid cysts occurring at unusual locations involving upper left maxillary region lateral to the nose and pinna of the ear.

    Full Text Available Lymphoepithelial cysts are benign, slowly growing unilocular or multilocular lesions that appear in the head and neck. They are also called Branchial cyst. The head and neck sites are the salivary glands(more commonly parotid and rarely submandibular gland and the oral cavity (usually the floor of the mouth. there are various methods of investigation available today, of which Fine needle aspiration cytology (FNAC can be used to provide an immediate diagnosis of a lymphoepithelial cyst. The other investigations include, Ultrasonogram,and Computed tomography.It usually occurs due to the process of lymphocyte-induced cystic ductular dilatation and the confirmatory diagnosis is always made postoperatively by histopathological examination. The mainstay in the treatment of a lymphoepithelial cyst remains the surgical approach, which includes complete enucleation of the cyst along with total excision of the involved salivary gland. This is a report of a lymphoepithelial cyst involving the submandibular salivary gland and its management.

    Perineural cysts are common and usually detected incidentally during magnetic resonance imaging of the lumbosacral spine. Treatment is indicated only when the cyst is symptomatic. We report one such patients presented with cauda equina syndrome and another with low back pain with claudication. They underwent excision and duraplasty; both motor and sensory fibres were carefully separated from the cyst wall using a nerve root retractor and penfield. There was no nerve root damage or neural deficit. Symptoms were relieved postoperatively.

  6. A Case Report of Enterogenous Cyst

    Directory of Open Access Journals (Sweden)

    M. Amini, M.D.

    2007-09-01

    Full Text Available Foregut cysts are various congenital lesions originated from emberyonic foregut. Bronchogenic, enterogenous and neuroenteric cysts are the most frequent forms of foregut cysts. They create different clinical symptoms based on their location. Enterogenous cysts comprise 4-5 percent of posterior mediastinal cysts and include esophageal, gastric and enteric cysts. A 61 year old woman referred to surgical clinic with dysphasia and regurgitation 6 months ago whose illness aggravared over the last 3 months. In physical examination, a lesion was seen in the right site of posterior mediastinum. Surgical excision was done and a ciliated columnar epithelium with two thin muscular layers were reported in pathology. In reality, the distinction between esophageal and bronchogenic cysts is not always clear. Both cysts present in mediastinum and their epithelial tissues are non-specific, however presence or lack of muscle layer in cyst-wall, proximity to gastrointestinal tract or tracheobronchial tree, adaption of clinical symptoms with paraclinic results and observations during surgical procedure can reveal certain diagnosis.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident.

    Echinococcosis is endemic in various regions of Turkey. Cardiac involvement in echinococcosis is rare, and lone cardiac hydatid cysts are even more unusual. Because cardiac hydatid disease can be fatal, even asymptomatic patients are optimally referred for surgical treatment. We present a rare case of a lone, primary, mobile hydatid cyst in the left atrium of a 62-year-old woman. The cyst caused dyspnea from left ventricular inflow obstruction. In addition to reporting the patient's fatal case, we discuss cardiac hydatid cysts in terms of the scant medical literature. PMID:27303247

    Spinal bronchogenic cysts are rare congenital lesions. The authors describe their experience in the treatment of a 17-year-old boy who presented with back pain and paresthesia in both lower extremities. Lumbar MR imaging revealed the presence of an intramedullary cystic lesion at the conus medullaris and histopathological analysis revealed a bronchogenic cyst. To the best of the authors' knowledge, this is the first report of an intramedullary spinal bronchogenic cyst arising at the conus; all previously reported spinal bronchogenic cysts were either intradural extramedullary or not located at the conus.

    Dermoid cyst of the parotid gland is a rare clinical entity. Definitive clinical diagnosis is often difficult to determine preoperatively because of the lack of pathognomonic features. The most frequent location of a parotid dermoid cyst is a triangular area lying above the pinna. Imaging studies do not definitely diagnose a parotid dermoid cyst. Although parotid dermoid cyst is (generally) well-encapsulated, complete removal of the cyst wall is not sufficient to cure it, so it is mandatory to perform careful excision of the cyst by parotidectomy, in terms of preserving facial nerve integrity. Histopathology of the parotid gland tumor removed by parotidectomy makes a diagnosis of certainty, by revealing a cyst wall with keratinization of the squamous epithelium and the presence of skin annexes (hair follicles, sweat glands, sebaceous glands). We present a rare case of parotid dermoid cyst in a 21-year-old male patient with symptoms and imaging rather suggestive of arch I branchial cyst and a brief review of data in the medical literature of the last 20 years.

    Full Text Available Danmarks Pædagogiske Universitetsskole ved Aarhus Universitet har siden 2006 eksperimenteret med systematisk videooptagelse og -streamning af undervisning på udvalgte kandidat- og masteruddannelser. De studerende er begejstrede for denne praksis og de muligheder, dette giver de studerende for at understøtte deres læring. Men selvom de studerende har vist sig at bruge den videostreamede undervisning på en endog særdeles hensigtsmæssig måde, har der, både blandt studerende og især blandt underviserne, været modstand mod dels overhovedet at optage, dels at gøre optagelserne af undervisningen offentligt tilgængelige for studerende og andre interesserede. Der kan således iagttages nogle barrierer i forhold til ibrugtagning af videooptaget undervisning på universitetsniveau, idet underviserne for en umiddelbar betragtning tilsyneladende for det første har nogle forbehold af psykologisk, for det andet af juridisk karakter og for det tredje af organisatorisk art. Et af de centrale spørgsmål i denne forbindelse synes således at være, om optagelse af undervisning muliggør en ledelsesmæssig evaluering af den enkelte undervisers undervisningspraksis. Et andet centralt spørgsmål er tilsyneladende, om optagelse af undervisningen, der muliggør genbrug, gør underviserne overflødige. Forfatterne til denne artikel er imidlertid af den opfattelse, at undervisernes modstand følger af en anden, og mere grundlæggende, diskrepans, nemlig diskrepansen mellem det at forske og det at undervise. Efter en indledende begrebsafklaring, præsenterer forfatterne i denne artikel erfaringerne med tilbud af videostreamet og podcastet universitetsundervisning til studerende på Danmarks Pædagogiske Universitetsskole med henblik på en diskussion af de potentialer og især de barrierer, der kan iagttages i forhold til en mere systematisk, large-scale brug af castet universitetsundervisning.

    Symptomatic sacral perineural cysts are uncommon. Several hypotheses have been proposed to explain the etiologies of perineural cysts, but the accurate etiologies remain unclear. We experienced two cases of symptomatic sacral perineural cysts (Tarlov cysts) in one family, who presented with perianal paresthesia. Both of them were operated and postoperatively their symptoms were disappeared immediately. We experienced the excellent treatment outcome with the surgical management of symptomatic perineural cysts in the sacral region. We assume that the theory of congenital origin including a familial tendency is the most plausible of the hypotheses that have been proposed.

    temadagen præsenteres nye resultater og metoder til at vurdere stress hos mink. I en metode måles koncentrationen af nedbrydningsprodukter af hormonet cortisol i gødning fra mink. Der er en række fordele ved denne metode, frem for blodprøvetagning. Forsøg viste, at hovedparten af cortisol udskilles i fæces...... (83 %) frem for i urin (17 %), samt at omsætningen af radioaktivt mærket cortisol ikke er forskellig mellem mink med hhv. lav og høj forekomst af stereotypi. Denne viden kan bruges til bedre at forstå koblingen f.eks. unormal adfærd og stress hos mink.......Sammendrag Stress indgår som et element ved vurdering af dyrevelfærd. Endvidere kan stress mål anvendes i undersøgelser, hvor forskellige typer af avl, burmiljø og pasning af mink sammenlignes. Men hvad er stress egentlig og hvordan måles det?

    Full Text Available I denne artikel undersøger vi potentialerne for at lære matematik gennem programmering af robotter. Vi foreslår en model med tre indbyrdes afhængige læringspotentialer, som programmering fordrer. Det omfatter elevens evne til at; (1 tænke i algoritmer, (2 producere viden og artefakter gennem brug af matematik og (3 foretage abstraktion og indkapsling. Programmering er blevet en del af grundskolens læringsmål i flere lande. I Danmark er programmering et læringsmål i forenklede fælles mål for Fysik/Kemi og desuden en del af den nationale undervisningsvejledning for matematik. En analyse af potentialerne i at anvende programmering i forbindelse med disse fag er derfor væsentlig. I denne artikel fokuserer vi på samspillet mellem matematik og programmering gennem litteraturstudier og analyse af empiriske situationer fra undervisning i programmering af LEGO Mindstorms. Teoretisk anvendes den instrumentelle tilgang til teknologi i matematikundervisning. Analysen viser en række måder, hvorpå didaktisk opmærksomhed på epistemisk forhandling kan understøtte læring af matematik gennem programmering.

    Institute of Scientific and Technical Information of China (English)

    Jianjun Sun

    2016-01-01

    A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for different cysts, such as congenital, trauma, bleeding, inflammatory, instability, hydrostatic pressure, osmosis of water, secretion of cyst wall, and one-way-valve effect, etc. Up to now, many treatment methods are available for these different spinal canal cysts. One operation method can be applied in cysts with different types. On the other hand, several operation methods may be utilized in one type of cyst according to the difference of location or style. However, same principle should be obeyed in surgical treatment despite of difference among spinal canal cysts, given open surgery is melely for symptomatic cyst. The surgical approach should be tailored to the individual patient.

    Background Parathyroid cyst is an infrequent and unsuspected disease. There are more than 300 hundred cases reported in the world literature, a few of them are from Latin America. The experience of our centers and a review of the cases are presented. Methods Case report of a series of patients with parathyroid cyst from our institutions according to the CARE guidelines (Case Reports). A search of Medline, Embase, BIREME (Biblioteca Regional de Medicina) LILACS (Literatura Latinoamericana y del Caribe en Ciencias de la Salud), Google Scholar and Scielo (Scientific Electronic Library on Line) databases and telephonic or email communications with other experts from Latin-America was performed . Results Six patients with parathyroid cyst were found in our centers in Colombia. Most of them were managed with aspiration of the cyst. Two of them required surgery. Only one case was functional. Twelve reports from Latin America were found for a total of 18 cases in our region adding ours. Conclusions Parathyroid cysts are uncommonly reported in Latin America. Most of them are diagnosed postoperatively. Suspicion for parathyroid cyst should be raised when a crystal clear fluid is aspirated from a cyst. The confirmation of the diagnosis may be easily done if parathyroid hormone (PTH) level is measured in the cyst fluid. PMID:28149800

    Full Text Available Background: Different research groups reported a negative correlation between cancers and parasitical infections. As an example, the prevalence of a hydatid cyst among patients with cancer was significantly lower than its prevalence among normal population. Tn antigens exist both in cancer and hydatid cyst. This common antigen may be involved in the effect of parasite on cancer growth. So in this work, common antigens between hydatid cyst and cancers have been investigated. Materials and Methods: Different hydatid cyst antigens including hydatid fluid, laminated and germinal layer antigens, and excretory secretory antigens of protoscolices were run in SDS PAGE and transferred to NCP paper. In western immunoblotting, those antigens were probed with sera of patients with different cancer and also sera of non-cancer patients. Also, cross reaction among excretory secretory products of cancer cells and antisera raised against different hydatid cyst antigen was investigated. Results: In western immunoblotting, antisera raised against laminated and germinal layers of hydatid cyst reacted with excretory secretory products of cancer cells. Also, a reaction was detected between hydatid cyst antigens and sera of patients with some cancers. Conclusion: Results of this work emphasize existence of common antigens between hydatid cyst and cancers. More investigation about these common antigens is recommended.

  9. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    2010-01-01

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

    Background: Different research groups reported a negative correlation between cancers and parasitical infections. As an example, the prevalence of a hydatid cyst among patients with cancer was significantly lower than its prevalence among normal population. Tn antigens exist both in cancer and hydatid cyst. This common antigen may be involved in the effect of parasite on cancer growth. So in this work, common antigens between hydatid cyst and cancers have been investigated. Materials and Methods: Different hydatid cyst antigens including hydatid fluid, laminated and germinal layer antigens, and excretory secretory antigens of protoscolices were run in SDS PAGE and transferred to NCP paper. In western immunoblotting, those antigens were probed with sera of patients with different cancer and also sera of non-cancer patients. Also, cross reaction among excretory secretory products of cancer cells and antisera raised against different hydatid cyst antigen was investigated. Results: In western immunoblotting, antisera raised against laminated and germinal layers of hydatid cyst reacted with excretory secretory products of cancer cells. Also, a reaction was detected between hydatid cyst antigens and sera of patients with some cancers. Conclusion: Results of this work emphasize existence of common antigens between hydatid cyst and cancers. More investigation about these common antigens is recommended. PMID:26962511

    Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simple fenestration was done with immediate regression of symptom. When a disease develops in oculomotor cistern, precise evaluation with proper MRI sequence should be performed to rule out tumorous condition and prevent injury of the oculomotor nerve.

    2013-03-01

    During Acanthamoeba castellanii trophozoite-cysts differentiation, four morphological stages were identified by scanning electron microscopy: trophozoite, precyst, immature cysts, and mature cysts. Fluorescence microscopy reveals the presence of small cumulus of actin in the cytoplasm of precysts after treatment with rhodamine phalloidin. By the contrary, in mature cysts, fluorescence was not observed. However, when excystation was induced, large fluorescent patches were present. By transmission electron microscopy, encysting amebas showed small cytoplasmic vesicles containing fibrillar material, surrounded by a narrow area of thin fibrils. Similar appearance was observed in pseudopods and phagocytic invaginations. In addition, large aggregates of rod-shape elements, similar to the chromatoid bodies, described in other amebas, were present in the cytoplasm. These cysts presented large areas with orange fluorescence after treatment with acridine orange.

  16. Pilonidal cyst on the vault: case report

    Full Text Available Pilonidal cysts and sinuses are described as dermoid cysts which contain follicles of hairs and sebaceous glands. They clinically present as a classic case of inflammation which comes with pain, local infection and redness. The origin of pilonidal disease remains controverse. There are many hypothesis as lack of hygiene on the affected area and a penetration and growth of a hair in the subcutaneus tissue caused by constant friction or direct trauma on the damaged area. The option for clinical treatment is very frequent. However, taking into consideration the incidence and the possibility of recidive, surgical treatment is presently recommended. Complications include cellulitis and abscess formation. Pilonidal cysts are mostly found on the sacral region. In the literature is found description of pilonidal cysts on the penis, interdigital region on the hands as well as on the cervical region. We present a case of pilonidal cyst located on the vault biparietal region, without malignant degeneration.

    2011-01-01

    Spinal intramedullary epidermoid cyst is a rare condition. Recurrent epidermoid cyst in the spine cord is known to occur. The authors describe a case of recurrent conus medullaris epidermoid cyst in a 24-year-old female. She initially presented at 7 years of age with bladder disturbance in the form of diurnal enuresis and recurrent urinary tract infection. MRI lumbar spine revealed a 4 cm conus medullaris epidermoid cyst. Since the initial presentation, the cyst had recurred seven times in the same location and she underwent surgical intervention in the form of exploration and debulking. This benign condition, owing to its anatomical location, has posed a surgical and overall management challenge. This occurrence is better managed in a tertiary-care centre requiring multi-disciplinary treatment approach.

    2012-07-01

    The pathogenesis of cysts that arise in the jaws is still not certain, and the underlying mechanisms of epithelial proliferation are not fully understood. Cysts of the jaw may involve a reactive, inflammatory, or neoplastic process. Cytogenetics, the study of the number and structure of chromosomes, has provided valuable information about the diagnosis, prognosis, and targeted treatment in many cancers, including oral squamous cell carcinoma. Cytogenetics can also provide information about the possible aetiology or neoplastic potential of a lesion, though to our knowledge no studies of this technique have been used for cysts in the jaws. In this pilot study we used cytogenetics in a series of 10 cysts (3 radicular, 4 dentigerous, 2 of the nasopalatine duct, and 1 dermoid). In all cases we found normal karyotypes. Further work and larger numbers are needed for a definitive study, but we can hypothesise from this pilot study that these cysts do not have cytogenetic aberrations and so have no neoplastic potential.

    Full Text Available A case of intraprostatic cyst is reported. The patient presented with a completely evacuated hydatid cyst of the prostate. The intraprostatic cystic cavity that was communicating with the urethra developed urinary stones. The patient had transurethral resection of the prostate, the stones in the cyst were pushed into the bladder and fragmented using a ballistic lithotripter. Pathological examination concluded to a prostatic hydatid cyst that had evacuated through the urethra and was complicated by stone formation within the residual cavity. Postoperative course was uneventful and follow-up did not show evidence of recurrence. This is the first case of hydatid cyst of the prostate to present as an intraprostatic stone pouch.

    1991-03-01

    Case 1: A lower abdominal large painful mass was recognized by palpation, CT scan and ultrasonography in a 64-year-old house wife. Urine cytology was negative. The mass at the dome of bladder was covered with normal epithelium cystoscopically. Aspiration cytology of the lower abdominal mass demonstrated no malignancy and total excision of urachal remnant with a portion of bladder wall was carried out. Histologically, the mass was an urachal cyst with granulomatous change infected with C group beta-streptococcus. Case 2: A 46 year-old male engineer complained of asymptomatic hematuria. Cystoscopic examination revealed a small bleeding lesion at the dome of bladder. Urine cytology was negative. CT scan and ultrasonography revealed a tiny cystic mass lesion with irregular density. Biopsy or aspiration cytology appeared difficult because of the size and localization of the mass. En bloc segmental resection of urachal remnant was carried out. Since intraoperative rapid histological examination of the specimen confirmed no malignancies, dissection of pelvic lymph node was not performed. Urachal cysts presented above were suspicious of malignant degeneration from findings of imaging examination. Either preoperative or intraoperative histological examination in such cases appears to be indispensable to avoid unnecessary extensive operation as well as to perform radical operation required for malignant lesions.

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    2015-01-01

    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

    Full Text Available Abstract Background It is acknowledged that total cyst excision is a safe and ideal surgical treatment for congenital biliary duct cyst, compared to simple internal drainage. The aim of this study was to determine the optimal operation occasion and the effect of laparoscopy on congenital biliary duct cyst based upon total cyst excision. Methods From January 2002 to January 2011, 217 patients were admitted to Southwest Hospital for congenital biliary duct cyst. To determine the optimal surgery occasion, we divided these subjects into three groups, the infant group (age ≤ 3 years, the immaturity group (3 18 years, and then evaluated the feasibility, risk and long-term outcome after surgery in the three groups. To analyze the effect of laparoscopic technique on congenital biliary duct cyst, we divided the patients into the laparoscopy and the open surgery groups. Results Among the three groups, the morbidity from cholangiolithiasis before surgical treatment had obvious discrepancy (p 0.05. Similarly, no significant discrepancy was observed in the morbidity from postoperative complications or long-term postoperative complications (p > 0.05 between the laparoscopic and the open surgery groups. Conclusions We conclude that total cyst excision should be performed as early as possible. The optimal treatment occasion is the infant period, and laparoscopic resection may be a new safe and feasible minimally invasive surgery for this disease.

  11. Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum

    Directory of Open Access Journals (Sweden)

    Safak Ozturk

    2014-01-01

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

    2016-01-01

    The authors report the case of a giant medial meniscal cyst in an osteoarthritic knee of an 82-year-old woman that was successfully treated with only arthroscopic cyst decompression. The patient noticed a painful mass on the medial side of the right knee that had been gradually growing for 5 years. Magnetic resonance imaging showed an encapsulated large medial cystic mass measuring 80×65×40 mm that was adjacent to the medial meniscus. An accompanying horizontal tear was also detected in the middle and posterior segments of the meniscus. The medial meniscus was resected up to the capsular attachment to create bidirectional flow between the joint and the cyst with arthroscopic surgery. Magnetic resonance imaging performed 14 months postoperatively showed that the cyst had completely disappeared, and no recurrence was observed during a 2-year follow-up period. An excellent result could be obtained by performing limited meniscectomy to create a channel leading to the meniscal cyst, even though the cyst was large. Among previously reported cases of meniscal cysts, this case is the largest to be treated arthroscopically without open excision.

    2011-02-15

    The purpose of this study is to assess the prevalence of abnormal CT findings in patients with surgically proven ruptured endometriotic cysts, as compared with those abnormal CT findings of ruptured ovarian functional cysts. This study included 13 retrospectively identified patients with surgically confirmed ruptured ovarian endometriotic cysts and who had also undergone preoperative CT scanning during the previous seven years. As a comparative group, 25 cases of surgically confirmed ruptured ovarian functional cysts were included. We assessed the morphologic features of the cysts and the ancillary findings based on CT. For the endometriotic cysts, the mean maximum cyst diameter was significantly larger than that of the functional cysts (70.1 mm versus 36.4 mm, respectively, p < 0.05). The endometriotic cysts frequently had a multilocular shape and a thicker cyst wall, as compared to that of functional cysts, and these differences were statistically significant. Among the ancillary findings, endometriotic cysts showed a significantly higher prevalence of loculated ascites, ascites confined to the pelvic cavity without extension to the upper abdomen, and peritoneal strandings and infiltrations (p < 0.05). Although 11 of the 25 cases of functional cysts showed active extravasation of contrast material at the ovarian bleeding site, only one of 13 cases of endometriotic cysts showed active extravasation. The diagnosis of ruptured endometriotic cyst should be suspected for a woman in whom CT reveals the presence of multilocular or bilateral ovarian cysts with a thick wall and loculated ascites confined to the pelvic cavity with pelvic fat infiltrations

    Full Text Available Abstract Epidermoid and dermoid cysts represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are found, and teratoid cysts when other tissue such as muscle, cartilage, and bone are present. In this article, we present the case of an epidermoid cyst, with an oral as well as a submental component, in an 11 year old boy who presented with complaints of a mass in the oral cavity, difficulty chewing and swallowing of solid foods for about 3 years. He was admitted to the otolaryngology department. On examination, a mass displacing the tongue superiorly and posteriorly was noticed. An MRI scan was done and showed a 40 × 35 mm well-circumscribed non-enhancing cystic mass extending from the sublingual area to the level of the thyroid notch. The content of the cyst was homogenous. On examining the neck, a firm swelling was also noticed in the submental area, extending down to the thyroid notch. Under general anesthesia and with nasotracheal intubation, the patient underwent surgical removal of the mass. Extraorally, a midline submental horizontal incision was performed through the mucosa overlying the swelling and the cyst was dissected from the surrounding tissues and removed. On histological examination, acidophilic stratum corneum and basophilic dot like staining of stratum granulosum, which is the hallmark of an epidermoid cyst, were seen. The patient did well postoperatively, and no recurrence was noticed at the 6-months follow-up.

    Full Text Available The first prenatal detection of an ovarian cyst was by Valenti in 1975. Since then antenatal and neonatal ovarian cysts are encountered more frequently due to the improvement of imaging techniques as well as routine antenatal ultrasound scanning. We discuss here the laparoscopic management of three cases of neonatal ovarian cysts. This approach is well tolerated by neonates, and it may overcome the controversy between the ′wait and see′ policy and early surgical intervention, as laparoscopy has both diagnostic and therapeutic value with minimal morbidity, and ovarian salvage whenever possible.

    17-year-old and 14-year-old brothers were referred for evaluation of the cystic lesions on the mandibular anterior area with no symptoms. Neither their mother nor the brothers could recall any past trauma to those areas. Panoramic and intraoral radiographs revealed moderately defined cystic lesions on their mandibular anterior areas. Biopsies on both lesions revealed simple bone cysts. Hereditary cause or familial history of simple bone cysts could not be found in literature review. This case may have been a coincidence. However, further investigation is needed to find the cause of simple bone cysts occurring in patients those are closely related.

    Full Text Available Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction. Because of cosmetic problems, they are often diagnosed at an early stage. These lesions are mostly revealed unilaterally but also can be seen on both sides. In this case report, a patient who complained of nasal obstruction and then diagnosed with bilateral nasoalveolar cysts and treated by sublabial excision is presented and clinical features and treatment approaches are discussed with the review of literature.

    We recently encountered two large intrasellar arachnoid cysts extending to the suprasellar region. The intensity of the cyst contents was identical to that of the cerebrospinal fluid on both T1- and T2-weighted MRI. On contrast-enhanced MRI, the pituitary gland was compressed posteroinferiorly and flattened in the sella turcica. In this report of rare intrasellar arachnoid cysts the discussion is focused on dislocation of the pituitary gland. (orig.)

    Pulmonary multi-vesicular hydatid disease (HD) with Echinococcus granulosus is rare. A 28-year-old woman presented to our center with cough and respiratory distress. Chest x-ray and computerized tomography scan revealed bilateral giant cysts with water-lily sign (ruptured hydatid cysts). The left cyst was in vicinity of heart. With thoracotomy cysts of both lungs were removed. Thousands of translucent, homogenized small daughter cysts were discovered from the left side cyst. Pathologic examinations revealed the ruptured hydatid cysts of both lungs with daughter cysts on the left lung cyst. To best of our knowledge probably this is the first report of multi-vesicular HD in lung. We suppose that the heart pulsation was effective in the formation of daughter cysts.

    2012-01-01

    Full Text Available Botryoid odontogenic cyst (BOC is considered to be a polycystic variant of the lateral periodontal cyst (LPC as the specimen resembled a cluster of grapes. It is a non-inflammatory odontogenic cyst. The BOCs can be unicystic or multicystic. These cysts have potential to extend in the bone and become multilocular and they have a high recurrence rate. Till now, only 73 cases of BOC have been reported. The pathogenesis of BOC is still debatable. We review different pathogenesis proposed for BOC and discuss a rare case of BOC developing from lining of an abnormally large LPC which showed aggressive behaviour in terms of growth and size.

    Background: A rare cause of spinal cord compression is spinal arachnoid cysts. Symptoms are caused by spinal cord compression, however, asymptomatic patients have been also reported. Treatment options depend upon symptom severity and clinical course. Case Description: We report the case of a 47-year-old patient who developed an intramedullary arachnoid cyst after removal of an intradural extramedullary cyst. Conclusion: Surgery should be considered early in a symptomatic disease course. Longstanding medullary compression may reduce the possibility of neurological recovery as well as secondary complications such as intramedullary cyst formation. PMID:27512608

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    Four perineurial cysts cases (Tarlov's cysts) are reported. The purpose of this study is to describe and to compare them with data from a literature review. The evaluation was performed among 88 adult patients with symptoms of radiculopathy, sacral pain, low back pain. Four patients revealed Tarlov's cysts (4.5%). The diagnosis was made by magnetic resonance imaging. Four cases underwent sacral laminectomy. Following surgery, the claudication pain resolved with no motor or sensory deficits. Tarlov's cysts should be considered as a differential diagnosis of sacral radiculopathy, sacral or lumbar pain syndromes and mainly to the lumbar disc prolapse. The goal of the surgical treatment is to relieve the neural compression and stop bone erosion.

    The purpose of this study was to investigate the surgical outcomes and to determine indicators of the necessity of surgical intervention. Twelve consecutive patients harboring symptomatic sacral perineural cysts were treated between 1995 and 2003. All patients were assessed for neurological deficits and pain by neurological examination. Magnetic resonance of imaging, computerized tomography, and myelography were performed to detect signs of delayed filling of the cysts. We performed a release of the valve and imbrication of the sacral cysts with laminectomies in 8 cases or recapping laminectomies in 4 cases. After surgery, symptoms improved in 10 (83%) of 12 patients, with an average follow-up of 27 months. Ten patients had sacral perineural cysts with signs of positive filling defect. Two (17%) of 12 patients experienced no significant improvement. In one of these patients, the filling defect was negative. In conclusion, a positive filling defect may become an indicator of good treatment outcomes.

    The hydatid cyst of kidney is rare, it ranks third among all visceral localisations. The authors report a series of 90 cases renal hydatid cyst from 1972 to 2000. The middle age is 36 years with female predominance. Renal hydatid cyst often has a suggestive clinical presentation; flank mass in 84%, pain in 74% and sometimes a specific presentation hydaturia in 29%. The hydatid serology is positive in 55% and preferring ultrasonography and computed tomography in diagnosis of renal hydatid cyst. Surgical treatment is now well defined. Conservative treatment occupes a predominant place 84% and resection of the proeminent dome is usually efficient. Total nephrectomy should only be considered in the case of a completely destroyed kidney (16%) of cases. Post-operative course is generally uneventful and reexpansion of renal parenchyma is observed in 93% indicating the benign nature of this disease.

    Purpose: To describe the findings of sacral meningeal cysts (SMCs) on MR myelography and assess its value for the diagnosis of SMCs. Material and Methods: We evaluated the MR images and MR myelograms obtained from 10 patients with SMC. MR myelograms were obtained using a 2D or 3D single-shot fast spin-echo sequence. In 5 patients, X-ray myelograms and postmyelographic CT images were compared with the MR myelograms. Results: A total of 33 SMCs were diagnosed within the spinal canal and/or sacral foramen. MR myelograms clearly revealed each cyst as a well-defined mass showing hyperintensity (10 cysts) or isointensity (23 cysts) compared to cerebrospinal fluid. MR myelograms demonstrated SMCs better than X-ray myelograms and postmyelographic CT images in 3 of the 5 patients. Conclusion: MR myelography can be an adjunct to conventional imaging techniques when surgical treatment is indicated, because it can precisely delineate the extent of SMCs. (orig.)

    Full Text Available A 21-year-old male with developmental delay presented with abdominal pain of two days' duration. He was afebrile and his abdomen was soft with mild diffuse tenderness. There were no peritoneal signs. Plain x-ray demonstrated a large air-filled structure in the right upper quadrant. Computed tomography of the abdomen revealed a 9×8 cm structure adjacent to the hepatic flexure containing an air-fluid level. It did not contain oral contrast and had no apparent communication with the colon. At operation, the cystic lesion was identified as a duplication cyst of the sigmoid colon that was adherent to the right upper quadrant. The cyst was excised with a segment of the sigmoid colon and a stapled colo-colostomy was performed. Recovery was uneventful. Final pathology was consistent with a duplication cyst of the sigmoid colon. The cyst was attached to the colon but did not communicate with the lumen.

    1999-10-01

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    Echinococcosis is a cyclozoonosis characterized by cystic lesions usually situated inside or outside the liver. We discuss the case of a 77-year-old woman with a recurrent hydatidosis with a cyst arising from the liver, growing through the lateral right abdomen wall, and reaching the subcutaneous tissue of the lumbar region. In the literature, rare subcutaneous or muscular localizations of hydatid cysts are described, however, there is no mention of a cyst growing over the abdominal wall muscles, shaped like an hourglass, partially in the liver and partially in the subcutaneous tissue, as in our case.We have not found any pathogenetic explanation for this growth pattern which is not typical of the biological behaviour of a hydatid cyst.

    Epidermoid cysts are malformations that are rarely observed in the submental region. Imaging has an important role in surgical planning according to the size and location of the cyst in relation to geniohyoid and mylohyoid muscles. This article reports the case of a 15-year-old female patient complaining of submental swelling. The differential diagnosis included infection, tumor, ranula, and abnormalities during embryonic development. The lesion was surgically excised using an extra-oral approach. The histopathological examination revealed a cyst wall lined with stratified squamous epithelium with the presence of several horny scales consistent with the diagnosis of an epidermoid cyst. No recurrences were found after 1 year of follow-up. PMID:27547744

    The cistern of the velum interpositum is a space located between the corpus callosum dorsally and the roof of the third ventricle ventrally. Lesions located within the velum interpositum are rare and include meningiomas, pilocytic astrocytomas, atypical teratoid/rhabdoid tumors and arachnoid cysts. Epidermoid cysts in this location have not been reported previously. We report the clinical and radiological features of two patients with epidermoid cysts located in the velum interpositum. The patients presented with gait difficulty and features of raised intracranial pressure and magnetic resonance imaging demonstrated large tumors in the velum interpositum with intensities suggestive of epidermoid cysts. There was ventral displacement of the internal cerebral veins and dorsal displacement of the corpus callosum in keeping with a mass in the velum interpositum. Tumors of the third ventricle displace the internal cerebral veins dorsally. A transcallosal approach was used in both patients to effectively excise the tumors.

    An air-filled paratracheal cyst is a common radiological finding. It may be a congenital defect or an acquired lesion. 'Acquired paratracheal cyst' is the term given to the acquired abnormalities, which usually arise in adults. They result from a weakness of the tracheal wall, and they may be caused by trauma, infection, high pressure injuries, long lasting tracheostomy, and obstructive tracheal disease. Majority of the paratracheal air cysts are asymptomatic and are discovered incidentally on radiological images. Also, the management is primarily conservative treatment. Here, we report a case of an infected paratracheal air cyst on the right posterolateral wall of the trachea, which developed into an abscess and was visualized on follow-up multidetector computed tomography and was surgically removed due to persistent symptoms.

    The testicular epidermoid cyst is an uncommon benign tumor that represents 1% to 2% of resected testicular masses. The observation of the characteristic ultrasonographic features of these lesions facilitates their diagnosis and may make it possible to perform enucleation, obviating the need for orchidectomy. We present two cases in which the testicular epidermoid cysts were diagnosed preoperatively and their presence confirmed after conservative surgery. We review the literature concerning imaging studies and the management of these lesions. (Author) 9 refs.

    Dentigerous cysts form from accumulation of fluid between reduced enamel epithelium and the crown of an unerupted tooth. They cause several difficulties such as swelling, non-eruption of the involved teeth, and displacement of adjacent teeth, and thus require early detection and prompt treatment. Treatment ranges from marsupialisation to enucleation. Enucleation is rarely used in children compared with marsupialisation. This paper discusses successful use of enucleation for treating a dentigerous cyst and explains the need for such a radical procedure.

    Cysts arising in the penis are uncommon and can be found anywhere from the urethral meatus to the root of the penis involving glans, foreskin, or shaft. Median raphe cysts account for the majority of penile cystic lesions reported in the literature. As their name suggests, they arise on the ventral midline of the penis that extends from the urethral meatus to the scrotum and perineum. Proposed hypotheses for their origin as well as their diverse morphology are discussed.

    Full Text Available Pericardial cysts are rare benign congenital mediastinal lesions. It accounts 30% of all mediastinal cysts. They are usually asemptomatic. They can produce the compression of the mediastinal structures typically caused the symptoms of dyspnea, thoracic pain, tachicardia and cough due to the unusual large size of the cyst. It can performed symptoms of lung atelectasia. The case was a sixty-five years old woman followed with a diagnosis of COPD for seven years. The patient was admitted to our center with the diagnosis of elevation of the right hemidiaphragm on chest radiography. The computed tomography revealed a cystic lesion adjacent to the right hemidiaphragm and cyst excision was performed via right thoracotomy. Patient%u2019s postoperative clinical findings indicated that the symptoms of COPD regressed completely and the patient did not require any further bronchodilator therapy. The aim of this case report is to demonstrate that the pericardial cysts can be missed in chest radiographs and impression of cysts may cause COPD like symptoms in these patients.

  12. Primary hydatid cyst in gastrocnemius muscle

    2012-01-01

    Full Text Available Cystic echinococcosis, which is caused by the larval stages of Echinococcus granulosus, results from the presence of one or more massive cysts or hydatids, and can involve any organ, including the liver, lungs, heart, brain, kidneys, and long bones. Muscle hydatidosis is usually secondary in nature, resulting from spread of larval tissue from a primary site after spontaneous or trauma-induced cyst rupture or after release of viable parasite material during invasive treatment procedures. Primary muscle hydatidosis is extremely uncommon, because implantation at this site would require passage through the filters of the liver and lung. Intramuscular hydatid cyst can cause a variety of diagnostic problems, especially in the absence of typical radiologic findings. We present an unusual case of a primary hydatid cyst found in the popliteal fossa of the right knee of a 52-year-old woman, presenting as an enlarging soft-tissue tumor for 6 months associated with pain. The mass initially was diagnosed to be Backer′s cyst by ultrasonography, but later it was confirmed postoperatively through histopathological studies to be due to hydatid disease. In regions where hydatidosis is endemic, hydatid cyst should be included in the differential diagnosis of any unusual muscular mass.

    In a grid investigation, dinoflagellate cysts were collected from sediments in Xiamen Western Harbor in May of 2000,from which five species of cysts were identified: Alexandrium tamarensis, A. minutum, Lingulodinium polyedra,Gonyaulax scrippsae and Gymnodinium catenatum, account for about 21% in the species composition. The quantitative analysis of the sediments shows that the number of dinoflagellate cysts varies from 51 to 256 cysts/g of sediment, the highest value (>200 cysts/g) being recorded at the stations of the central part of the bay, while the lowest (<100 cysts/g) at the bay mouth. A good linear relationship is found between cyst amount and fine-grained sediments. Complex physiognomies on the seabed, topographty in the bay and weak water exchange are the main factors not only in cyst accumulation but also in their distribution pattern, and have resulted in the difference in cyst densities between the inner bay and the outer bay in the harbor.

    BACKGROUND: Choledochal cysts are classiifed into ifve types based on the location of the cyst. Mixed types of choledochal cysts are extremely rare. Only ifve cases of mixed typeⅠ andⅡ choledochal cysts have been reported, of which one was an adult case. We report a mixed typeⅠandⅡ choledochal cyst in a 25-year-old man. METHODS: The unusual nature of the choledochal cyst, suspected on magnetic resonance cholangiopancreatography RCP to be typeⅠ initially, was conifrmed by laparotomy to be a mixed typeⅠ+Ⅱ cyst. Excision of the cyst and hepaticojejunostomy were performed. RESULT: The operation was uneventful, and the patient recovered well. CONCLUSIONS: Mixed type choledochal cysts are rare, and may be missed on imaging, unless careful evaluation is done. The operative method may not need to be modiifed signiifcantly, as in the management of our case.

    Palatal cysts are always confusing by deifning their exact nomenclature or conclusive diagnosis. One of these presentations is globulomaxillary cyst which requires to be categorized under appropriate head for the management point of view. Though this entity appears to be of odontogenic in origin but because of its anatomical relation and histo-pathological background this is placed in non odontogenic group. Though the mechanism of its formation remains the same but this cyst cannot be mixed up with nasopalatine cyst as per their location. Globulomaxillary cyst appears as inverted pear shaped radiolucency in all radiological procedures. This remains asymptomatic for a long time and rarely gets infected. We present a 29-year-old male who reported with one year history of asymptomatic right side hard palate swelling. He was subsequently diagnosed as globulomaxillary cyst with the help of radiological modalities like computerized tomography and magnetic resonance imaging. This article will highlight mainly the clinical and radiological features of these cysts with particular reference to globulomaxillary cyst which is our presenting case.

    Full Text Available Paraurethral or Skene′s duct cysts are rare causes of interlabial masses in neonates. The diagnosis of Skene′s duct cysts in the neonatal period is based on its location, in relation to the urethra, and the demonstration of transitional epithelium in the cyst wall. The distinguishing features of paraurethral cysts are the displacement of urethral meatus by the mass and a cyst containing milky fluid. Thus, we report a case of a Skene′s duct cyst in a newborn which was treated by incision and drainage.

    Acanthamoeba castellanii, a free-living amoeba, causes a sight-threatening form of keratitis. Even after extensive therapies, corneal damage can be severe, often requiring corneal transplantation to restore vision. However, A. castellanii cysts are not eliminated from the conjunctiva and stroma of humans and can excyst, resulting in infection of the corneal transplant. The aim of this study was to determine whether elements of the innate immune apparatus, neutrophils and macrophages, were capable of detecting and eliminating A. castellanii cysts and to examine the mechanism by which they kill the cysts. Results show that neither innate immune cell is attracted chemotactically to intact cysts, yet both were attracted to lysed cysts. Both macrophages and neutrophils were capable of killing significant numbers of cysts, yet neutrophils were 3-fold more efficient than macrophages. Activation of macrophages with lipopolysaccharide and interferon-gamma did not increase their cytolytic ability. Conditioned medium isolated from macrophages did not lyse the cysts; however, prevention of phagocytosis by cytochalasin D inhibited 100% of macrophage-mediated killing of the cysts. Conditioned medium from neutrophils did kill significant numbers of the cysts, and this killing was blocked by quercetin, a potent inhibitor of myeloperoxidase (MPO). These results indicate that neither macrophages nor neutrophils are chemoattracted to intact cysts, yet both are capable of killing the cysts. Macrophages killed the cysts by phagocytosis, whereas neutrophils killed cysts through the secretion of MPO.

    2012-01-01

    A 5-year-old neutered male domestic shorthair cat was presented for examination of a subcutaneous mass in his tail. The mass was firm, non-painful, oval, and approximately 2.5 × 3.5 cm. Surgical exploration revealed a well-circumscribed, encapsulated mass. The mass was removed and sectioned for histopathological examination. In gross section, it was filled with numerous dark hairs. Histologically the mass was consisted of haired skin with dermal cystic structures lined by stratified squamous epithelium. The cyst lumen contained squamous debris and filled with keratinous material. Numerous hair shafts were extended from the wall of the cyst. The sebaceous and apocrine gland adnexal structures were also observed which confirmed the diagnosis of dermoid cyst. No tumor recurrence was observed after surgery in fallowing checkups. Cutaneous or subcutaneous cysts of all types are considered rare in cats and to our knowledge this is the third reported case of cutaneous dermoid cyst of cats in veterinary literature which is different from the other cases because it occurred in dorsal midline in tail area whereas others occurred in flank area.

    2010-01-01

    Full Text Available Surgical options for suprasellar arachnoid cyst are cystoperitoneal shunt, craniotomy fenestration and endoscopic fenestration. Endoscopic management has been found to be safe and effective. We report our experience with endoscopic management in 12 (male five, female seven; age range 8 months to 42 years patients with suprasellar arachnoid cyst. The endoscopic procedure included lateral ventricle puncture by precoronal burr hole and superior and inferior wall of the cyst was communicated with the lateral ventricle and the interpeduncular cistern respectively. All patients had hydrocephalus. Four pediatric patients had macrocephaly. All adult patients had visual disturbances. One adult patient presented with psychomotor disturbance along with features of raised intracranial pressure. All cases improved following endoscopic treatment. There were no complications or death. One patient required VP shunt. Postoperative MRI showed significant reduction in cyst volume in 11 patients. Follow-up ranged from 6 months to 6 and a half years. Our study suggests that endoscopic technique is a safe and effective alternative treatment for suprasellar arachnoid cyst. It prevents complications such as subdural effusion and intracranial hematoma, which are not uncommon with craniotomy fenestration.

  4. Cerebellar ependymal cyst in a dog.

    2008-11-01

    An 11-week-old, male, Staffordshire Bull Terrier had a history of generalized ataxia and falling since birth. The neurologic findings suggested a localization in the cerebellum. Magnetic resonance imaging of the brain was performed. In all sequences the area of the cerebellum was almost replaced by fluid isointense to cerebrospinal fluid. A complete necropsy was performed after euthanasia. Histologically, the lesion was characterized by extensive loss of cerebellar tissue in both hemispheres and vermis. Toward the surface of the cerebellar defect, the cavity was confined by ruptured and folded membranes consisting of a layer of glial fibrillary acidic (GFAP)-positive glial cells covered multifocally by epithelial cells. Some of these cells bore apical cilia and were cytokeratin and GFAP negative, supporting their ependymal origin. The histopathologic features of our case are consistent with the diagnosis of an ependymal cyst. Its glial and ependymal nature as demonstrated by histopathologic and immunohistochemical examination differs from arachnoid cysts, which have also been reported in dogs. The origin of these cysts remains controversial, but it has been suggested that they develop during embryogenesis subsequent to sequestration of developing neuroectoderm. We speculate that the cyst could have been the result of a pre- or perinatal, possibly traumatic, insult because hemorrhage, and tissue destruction had occurred. To our knowledge, this is the first description of an ependymal cyst in the veterinary literature.

    Full Text Available The purpose of this study is to describe transient macular cysts in an infant and correlate their occurrence with normal development events. A newborn Caucasian girl presented with a protruding corneal mass in her left eye at birth. She underwent a complete ophthalmic examination. A keratinized staphylomatous malformation involving the entire cornea and precluding further visualization of the anterior and posterior segment was observed in the left eye. Spectral domain optical coherence tomography (SD-OCT of the right eye performed when the child was approximately 6-week-old had revealed an unexpected finding of macular cysts involving the inner nuclear and outer retinal layers. Corneal transplant in the left eye was performed a month later. Ocular examination under anesthesia just prior to surgery revealed normal intraocular pressure, anterior segment and retina in the right eye. SD-OCT was normal in both eyes and showed complete resolution of the cysts in the right eye. The patient had not been on any medications at that time. Although clinical retinal examination might be unremarkable, SD-OCT may reveal cystic spaces in the macula. In the absence of conditions known to be associated with macular edema, transient macular cysts may arise due to a developmental incompetence of the blood-retinal barrier or may represent transient spaces created during normal migration of retinal cells. Further study is warranted to delineate the entity of transient macular cysts in infancy.

    Liu, Roy; Adler, Douglas G

    2014-07-01

    Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts. Endoscopic ultrasound (EUS) has been widely used as a modality for the evaluation and diagnosis of duplication cysts. EUS is the diagnostic tool of choice to investigate duplication cysts since it can distinguish between solid and cystic lesions. The question of whether or not to perform EUS-fine needle aspiration (EUS-FNA) on a lesion suspected of being a duplication cyst is controversial as these lesions can become infected with significant consequences, although EUS-FNA is often required to obtain a definitive diagnosis and to rule out more ominous lesions. This manuscript will review the literature on duplication cysts throughout the body and will also focus on the role of EUS and FNA with regards to these lesions.

    We describe a case of sacral perineural cyst presenting with complaints of low back pain with neurological claudication. The patient was treated by laminectomy and excision of the cyst. Tarlov cysts (sacral perineural cysts) are nerve root cysts found most commonly in the sacral roots, arising between the covering layer of the perineurium and the endoneurium near the dorsal root ganglion. The incidence of Tarlov cysts is 5% and most of them are asymptomatic, usually detected as incidental findings on MRI. Symptomatic Tarlov cysts are extremely rare, commonly presenting as sacral or lumbar pain syndromes, sciatica or rarely as cauda equina syndrome. Tarlov cysts should be considered in the differential diagnosis of patients presenting with these complaints.

    Seemingly intact cysts and sequential stages of disintegrating cysts of Toxoplasma were identified immunohistologically within developing microglial nodules in a Panamanian night monkey (Aotus lemurinus). This monkey had been successfully immunized and challenged 5 months earlier. This supports the hypothesis that glial nodules unassociated with Toxoplasma tachyzoites may represent the tombstone of a Toxoplasma cyst. Disintegration of cysts may give rise to clinical encephalitis in the presence of apparently adequate immunity.

    2014-04-01

    A less invasive transsphenoidal approach with a keyhole dural opening for intrasellar arachnoid cysts is described. This approach was used to address seven sellar cystic lesions with suprasellar extension; they were six intrasellar arachnoid cysts (IACs) and one Rathke's cleft cyst (RCC). In all cases, preoperative MRI revealed cerebrospinal fluid (CSF) intensity on both T1- and T2-weighted images. On preoperative contrast-enhanced MRI, five of the six IACs manifested posterior displacement of the flattened pituitary gland toward the dorsum sellae; one of the six IACs and the RCC exhibited a flattened pituitary gland on the anterior surface of the cyst. Wide cyst cisternostomy through a keyhole dural opening was carried out safely using a microscope with the support of a thin angled endoscope (30° and/or 70°, diameter 2.7 mm). As we aimed to avoid iatrogenic injury of the pituitary function, we found it difficult to obtain a sufficiently wide and precise opening of the cyst wall when the pituitary gland was located on the anterior surface of the cyst wall. Our approach facilitates safe cyst cisternostomy as wide as that obtainable by transcranial manipulation. In addition, CSF leakage is prevented by dural plasty using the fascia lata and stitching with 6-0 monofilament sutures. This technique can be adapted to address various sellar cystic lesions. However, as the posterior or anterior displacement of the normal pituitary gland in the presence of IACs or RCCs, respectively, affects the width of the cyst opening, our technique is more suitable for IACs than RCCs.

    2015-01-01

    Full Text Available Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50 mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

    Meniscal cysts are a rare disease constantly combined with a horizontal meniscal lesion. Currently, nuclear magnetic resonance (MRI) is the main diagnostic tool, because of its high sensitivity and specificity, and decompression arthroscopy combined with selective meniscectomy is the treatment of choice. The Authors report a case of a voluminous medial meniscal cyst where instrumental examination, MRI, was fundamental for the preoperative diagnosis of the horizontal meniscal lesion causing the cystic degeneration of the meniscus. The treatment performed was selective meniscectomy of the body and posterior horn of the medial meniscus and decompression of the voluminous cyst by arthroscopy. Physical examination after six months showed the complete resolution of swelling at the medial hemirima, no walking pain and normal range of motion.

    A case of phaeohyphomycosis is reported in a male renal transplant recipient with a nodular lesion in the right leg who was treated with immunosuppressing drugs. The lesion consisted of a purulent cyst with thick walls. The cyst was excised surgically, and the patient did not receive any antifungal therapy. One year later he remains well. Histological study of the lesion showed a granulomatous reaction of epithelioid and multinucleate giant cells, with a central area of necrosis and pus. Fontana-Masson staining demonstrated the presence of pigmented hyphal elements. The fungus Colletotrichum crassipes was grown in different cultures from the cyst. The in vitro inhibitory activities of eight antifungal drugs against the isolate were tested. Clotrimazole and UR-9825 were the most active drugs. This case represents the first known reported infection caused by this rare species. PMID:11376082

    Large type 1 cysts are prone to perforation. Furthermore, insufficient drainage with subsequent abscess is a frequent problem of large cysts. We report here a case of a 19-year old man who was admitted to the hospital with pain in the right upper quadrant and epigastric region. An asymmetrical right upper quadrant enlargement was detected on physical examination. Ultrasonography and computerized tomography revealed a type 1 giant hydatid cyst in the right hepatic lobe, measuring 16 cm in diameter. During operation, partial cystectomy and drainage were done. The large dead space was obliterated by the 'sandwich' method. Omentum and gelatin sponges were used to fill the cavity. The postoperative period was uneventful and the patient was discharged on the 5th postoperative day.

    Full Text Available Hydatidosis due to Echinococcus granulosus is an endemic parasitic zoonosis characterized by worldwide distribution particularly in Mediterranean countries. The most commonly involved anatomical locations are the liver and lung. Occasionally the cyst may progressively increase in size, mimicking gross ascites or intrabdominal tumor. Herein, are reported a case of a 40-year-old patient with a giant exophytically expanded hepatic echinococcus cyst, misdiagnosed as an abdominal malignancy during formal investigation. The patient was admitted to the hospital complaining for mild diffuse abdominal tenderness, moderate abdominal pain, nausea, diarrhoea, and vomiting. A CT scan revealed the presence of a giant abdominal mass 25×21×14 cm, resembling a tumor, adherent to the liver edges and parietal peritoneum, displacing intestinal loops. During the ensuing days the patient’s clinical condition worsened, and he became febrile. Exploratory laparotomy was performed, and an exophytically grown giant liver hydatid cyst was removed, despite the radiological findings and the preoperative clinical suspicion.

    Full Text Available Increased radiological tests have facilitated the discovery of kidney cysts, which sometimes do not meet clear criteria for benignity or malignancy. Among these lesions, the hyperdense cysts pose a challenge to all those responsible for their diagnosis and treatment. For such reasons we decided to present the case of a 23-year-old female patient with a history of sickle cell anemia, who attended the emergency department of the Dr. Gustavo Aldereguía Lima University General Hospital due to colic-like pain in the left lumbar region unresponsive to analgesics. She was diagnosed with category II renal cyst according to Bosniak classification using computed tomography with and without intravenous contrast.

    Full Text Available Postoperative maxillary cyst is a quite rare delayed complication of surgical intervention associated with maxillary sinuses. It occurs many years after surgery. This paper describes a 54-year-old woman presenting with swelling of left cheek for seven-years duration. The orthopantomograph revealed a unilocular cystic radiolucency with well-defined margins in left maxillary sinus. In the computerized tomography, the cyst had a sclerotic wall with bony condensations. Aspiration cytology revealed many neutrophil leukocytes. Cyst was drained and enucleated. Histopathologically, it had a fibrous wall with inflammation and focal reactive bone formation and lined by a respiratory-type epithelium. In the clinical history, it is learned that she had a maxillary sinus surgery 8 years ago and the diagnosis was made considering the clinical and histopathological findings.

    2015-09-01

    Full Text Available Hydatid cyst is especially prevalent in parts of Eurasia, north and east Africa, Australia, South America. Hydatid disease is a zoonotic infection caused by adult or larval stages of the cestode Echinococcus granulosus and affects both humans and mammals. The infection is transmitted to dogs when they are fed on infected viscera of sheep or other ruminant during the home slaughter of animals. In the present case series four cases of hydatid cyst occurring at the lung and liver sites are discussed. The symptoms and signs may be caused by a toxic reaction to the parasite or by local and mechanical effects, depending on the location and nature of the cysts and the presence of complications. Early diagnosis and proper treatment will help to reduce the complication rate and prevent recurrence.

  13. Intracranial neurenteric cyst traversing the brainstem

    2015-01-01

    Full Text Available Neurenteric cysts (NECs, also called enterogenous cysts, are rare benign endodermal lesions of the central nervous system that probably result from separation failure of the notochord and upper gastrointestinal tract. Most frequently they are found in the lower cervical spine or the upper thoracic spine. Intracranial occurrence is rare and mostly confined to infratentorial compartment, in prepontine region [51%]. Other common locations are fourth ventricle and cerebellopontine angle. There are few reports of NEC in medulla or the cerebellum. Because of the rarity of the disease and common radiological findings, they are misinterpreted as arachnoid or simple cysts until the histopathological confirmation, unless suspected preoperatively. We herein report a rare yet interesting case of intracranial NEC traversing across the brainstem.

    A case of phaeohyphomycosis is reported in a male renal transplant recipient with a nodular lesion in the right leg who was treated with immunosuppressing drugs. The lesion consisted of a purulent cyst with thick walls. The cyst was excised surgically, and the patient did not receive any antifungal therapy. One year later he remains well. Histological study of the lesion showed a granulomatous reaction of epithelioid and multinucleate giant cells, with a central area of necrosis and pus. Fontana-Masson staining demonstrated the presence of pigmented hyphal elements. The fungus Colletotrichum crassipes was grown in different cultures from the cyst. The in vitro inhibitory activities of eight antifungal drugs against the isolate were tested. Clotrimazole and UR-9825 were the most active drugs. This case represents the first known reported infection caused by this rare species.

    AF1Q, a mixed lineage leukemia gene fusion partner, is identified as a poor prognostic biomarker for pediatric acute myeloid leukemia (AML), adult AML with normal cytogenetic and adult myelodysplastic syndrome. AF1Q is highly regulated during hematopoietic progenitor differentiation and development but its regulatory mechanism has not been defined clearly. In the present study, we used pharmacological and genetic approaches to influence chaperone-mediated autophagy (CMA) and explored the degradation mechanism of AF1Q. Pharmacological inhibitors of lysosomal degradation, such as chloroquine, increased AF1Q levels, whereas activators of CMA, including 6-aminonicotinamide and nutrient starvation, decreased AF1Q levels. AF1Q interacts with HSPA8 and LAMP-2A, which are core components of the CMA machinery. Knockdown of HSPA8 or LAMP-2A increased AF1Q protein levels, whereas overexpression showed the opposite effect. Using an amino acid deletion AF1Q mutation plasmid, we identified that AF1Q had a KFERQ-like motif which was recognized by HSPA8 for CMA-dependent proteolysis. In conclusion, we demonstrate for the first time that AF1Q can be degraded in lysosomes by CMA. - Highlights: • Chaperone-mediated autophagy (CMA) is involved in the degradation of AF1Q. • Macroautophagy does not contribute to the AF1Q degradation. • AF1Q has a KFERQ-like motif that is recognized by CMA core components.

    AIM: To determine the immunocytochemical pattern of expression of transforming growth factor (TGF) alpha, epidermal growth factor (EGF), and TGF beta in the three most common types of odontogenic jaw cyst. METHODS: Growth factor expression was detected in paraffin wax sections of odontogenic cysts (27 odontogenic keratocysts, 10 dentigerous cysts, and 10 radicular cysts) using a streptavidin-biotin peroxidase technique with monoclonal antibodies directed against TGF alpha (clone 213-4.4) and TGF beta (clone TB21) and a polyclonal antibody directed against EGF (Z-12). RESULTS: The epithelial linings of all cysts showed reactivity for TGF alpha which was mainly localised to basal and suprabasal layers. Odontogenic keratocyst linings expressed higher levels of TGF alpha than those of dentigerous and radicular cysts, with 89% (24/27) of odontogenic keratocysts exhibiting a strong positive reaction compared with 50% (five of 10) of dentigerous and radicular cysts, respectively. EGF reactivity was similar in all cyst groups, weaker than that for TGF alpha and predominantly suprabasal. TGF alpha and EGF were also detected in endothelial cells, fibroblasts and inflammatory cells within the cyst walls. The most intense TGF beta staining in odontogenic cysts was extracellular within the fibrous tissue capsules, irrespective of cyst type. CONCLUSIONS: These results, together with previous studies of EGF receptor, indicate differential expression of TGF alpha, EGF and their common receptor between the different types of odontogenic cyst, suggesting that these growth factors (via autocrine or paracrine, or both, pathways) may be involved in their pathogenesis.

    Full Text Available Introduction: The purpose of this study is to evaluate the distribution, clinical features, and treatment modalities of arachnoid cyst in our department. The study was carried out between April 1, 1996 and October 1, 2006 at the neurosurgery department, Ghaem hospital, Mashhad university of medical sciences. Material and Methods: Twenty patients with arachnoid cyst underwent surgery between April 1, 1996 until October 1, 2006, consisting of 12 males and 8 females ranging in age 5 to 68 years (mean age 32.4 years. Twelve patients underwent surgery and one patient underwent endoscopic fenestration, and cystoperitoneal shunting (medium pressure was performed in 7 patients. All patients were followed for minimum of 6 months after surgery. Results: During the study period, 20 patients were investigated. The cysts had strong predilection for the middle cranial fossa in 12 patients (60%, suprasellar region in 1 patient (5%, the cerebral convexity in 1 patient (5%, posterior cranial fossa in 2 patients (10%, cerebellopontine angle in 3 patients (15%, quadrigeminal cisterns in 1 patient (5%. All of 20 cysts had clearly unilateral distribution, 12 (60% were located on the left side and 8 (40% on the right side. The most common symptoms on presentation were epileptic seizures (46%, increased intracranial pressure (34%, visual impairment (5%, headache (10%, cerebellar sign (5%. Conclusion: Arachnoid cysts have a strong predilection for the middle cranial fossa that may be explained by a meningeal maldevelopment theory. We also conclude that the major indication for surgery in patients with arachnoid cyst is the presence of intractable seizures, increased intracranial pressure, and compression of neuronal tissues. Headache only is not a surgical indication.
