    Full Text Available A cross sectional study was conducted from October 2010 to March 2011 to assess the prevalence, cyst viability, organ distribution and financial losses of bovine hydatidosis in cattle slaughtered at Dessie municipal abattoir. Postmortem inspection, cyst characterization and financial loss estimations were conducted. Out of 610 inspected cattle, 83 (13.61% were harbouring a single or multiple hydatid cysts. Significantly (P<0.05 higher infection rate was observed in poor (22.89% than medium (12.99% and good (10.40% body condition scorings but significant variation (P>0.05 was not observed in different age groups. Anatomically, the cysts were distributed 68.67% in the lung, 14.46% in the liver, 6.02% in the kidneys, 1.2% in the heart and 9.64% were found both in the lung and liver. Of the total examined cysts (195 for fertility and viability, 27 (13.85% were fertile, 44 (22.56% were calcified, 124 (63.59% were sterile. The rate of cyst calcification was higher in the liver (78.14% than other organs whilst the fertility percentage was higher in the lung (14.65%. Of the total 27 fertile cysts subjected to viability test, 13 (6.67% were viable. Size assessment made on 195 cysts indicated that 153 (78.46% were small, 41 (21.03% were medium and one (0.51% were large sized cysts. In the present study, the total annual economic loss from organ condemnation and carcass weight loss due to hydatidosis was estimated as 681,333.87 Ethiopian birr which is about 39157.12 United States dollar per annum based on the local market prices in the study period. The result of this study revealed that hydatidosis is an economically important disease of cattle which necessitates designing of appropriate strategies for its control. [Vet.

    The viability of Acanthamoeba cysts after they have been stored in water at 4 degrees C for a period of 24 years was determined and to estimate their present degree of virulence as compared to its primary values. The viability of 17 amoebae isolates was examined using the eosin exclusion and in vitro excystation on agar plates (NNE). After the period of 24 years, only 3 isolates were found dead. The remaining 14 isolates after inoculation on NNE gave rise to new subcultures, although the percentage of living cysts measured by eosin exclusion was low (0-5%). Separate groups of mice were inoculated intranasally with 10 subcultures characterised by varying primary virulence. It was found that in 8 groups the mice were invaded (at varying degree), and some of them died. Taking into consideration the fact that some of the examined isolates completely lost their virulence only after 8 years of the in vitro cultivation, the obtained results are very intriguing. On the ground of these results one can assume that in the natural environment the period of viability for a cyst may be not shorter than 25 years, and, which is even more essential, they can maintain their invasive properties.

    A lesional study on human hydatidosis (localization, fertility of cysts, protoscolex viability, and histological structure) focused on 63 human hydatid cysts from patients operated at CHN of Nouakchott was conducted during the period 1997-2007. The authors report the following results: the annual surgical incidence rate was in the order of 1.2% per 100,000 inhabitants. The lung was the primary localization of cyst (52%) followed by the liver (33%), spleen (4%), brain (3%), heart (2%), breasts (2%), kidney (2%), diaphragm (1%), and peritoneum (1%). The pulmonary cysts were larger and more fertile (76%) with protoscoleces also more viable (70%) compared with liver cysts (67-62%). The histology of hydatid cysts revealed in most cases a histological structure consistent with that described in the literature: thick cuticle, membrane proligeous, and capsules visible.

    Odontogenic cysts (OC) are the most frequent lesions of the jaws and their constant epidemiological update is necessary and indispensable. Therefore the principal objective of this report was To determine prevalence and clinical-demographical characteristics of OC in a Mexican sample. 753 cases of OC coming from the archive of a head and neck histopathological teaching service, from January 2000 to December 2013, were included. OC cases were re-assessed according 2005 WHO classification. Chi square test was used to establish possible associations ( p pulpar necrosis and impacted teeth, radicular cyst and dentigerous cyst could be prevenible. Therefore, it is necessary to establish preventive strategies to diminish dental decay and programs of prophylactic extractions of impacted teeth, to in consequence decrease the prevalence of odontogenic cysts. Key words: Cyst, dentigerous cyst, mexican, odontogenic cyst, radicular cyst.

    Full Text Available Background Cystic echinococcosis (CE is a cosmopolitan zoonotic infection which is considered as a significant public health and economic concern. Livestock is the main intermediate host for Echinococcus granulosus. Objectives This study was conducted to evaluate the prevalence and fertility rate of hydatid cyst among livestock in Hamadan area, western Iran. Methods A total of 10626 livestock carcasses were examined through visual inspection in order to detect hydatid cyst in Hamadan industrial slaughterhouse, during 2015 - 2016. The viability and fertility of hydatid cyst were determined microscopically by flame cell activity and eosin dye uptake. Results The carcasses, including 8684 sheep, 1110 goats and 832 cattle were inspected in order to detect hydatid cyst. An overall CE was detected in 3% of the inspected carcasses with a prevalence rate of 5.3% in cattle, 3% in sheep and 1% in goats (P < 0.001. The prevalence rate of infection in the females (2.7% was more than males (0.3% (P < 0.001. All of the infected animals were aged one year or more. The highest rate of infection in internal organs was found in the lungs (47.2%. The highest and the lowest fertility rate of hydatid cyst were observed in sheep (69.3% and cattle (6.8%, respectively. The most of hydatid cysts which obtained from cattle (79.6% were suppurative or calcified. Conclusions This study shows that the prevalence rate of CE is considerable in the area and sheep appear to be the most important intermediate hosts for E. granulosus tapeworm.

    Specimens of Virginia opossums (Didelphis virginiana) in Michigan were examined over 1 year to document the presence of Besnoitia darlingi cysts. Cyst morphology, prevalence, seasonal variation, and tissue sites of isolation were studied. Histology and ultrastructural features of the detected cysts and bradyzoites were consistent with B. darlingi. In the opossums, B. darlingi had intracellular tissue cysts. Tissue cysts had a mean diameter of 560 microm and were separated from the host tissue by a thick (5-20 microm) cyst wall. Overall prevalence of B. darlingi cysts in opossums was 10.9% (15/137). Variations in the prevalence were detected during spring (3/17; 17.6%), summer (10/34; 29.4%), and fall (2/60; 3.3%). No cysts were detected in the specimens examined during winter (0/26; 0%). Numerous B. darlingi cysts were detected in ears, conjunctiva, tongue, abdominal muscles, diaphragm, stomach, heart, liver, kidney, lung, and spleen. Cysts were detected mainly in adult female opossums that were debilitated. Ear was the most frequent organ from which the cysts were reported (10/15; 66.7%) when compared individually with other body tissues (P<0.05).

    AIM: To provide a definitive evaluation of the prevalence of simple renal and hepatic cysts using spiral computed tomography (CT). PATIENTS AND METHODS: Contrast-enhanced abdominal CT studies from 617 patients (295 women, 322 men) attending for investigations unrelated to renal or hepatic pathology were included. The number of renal cysts, their location and the diameter of the largest cyst were recorded. Hepatic cysts were recorded as being either present or absent. RESULTS: Two hundred and fifty-four patients (41%) were found to have simple renal cysts and 110 patients were found to have simple hepatic cysts (18%). Both renal and hepatic cysts became more common with age. Renal cysts were significantly more common at all ages in men (p=0.001), and increased in both size (p=0.02) and number (p<0.05) with age. CONCLUSION: A major discrepancy has, until now, existed between autopsy prevalence of renal cysts and prevalence as reported by in-vivo third-generation CT or sonography studies. Using newer spiral CT machines, we have generated prevalence data closer to post-mortem findings. We have also shown a significant, but age dependent, association between the presence of simple hepatic and simple renal cysts (p=0.001)

    Objective. The purpose of this study was to determine the prevalence of Baker's cysts on MR images in a paediatric orthopaedic population, to investigate the association of Baker's cyst with joint fluid and joint disorders in children, and to compare the MR appearance of Baker's cysts in children with that previously reported in adults. Materials and methods. Reports from 393 MR studies of the knee performed in children aged from 1 to 17 years were retrospectively reviewed for the presence of a Baker's cyst, joint effusion, meniscal tear, anterior cruciate ligament tear, or any other joint disorder. Results. A Baker's cyst was identified in 6.3 % (25/393) of patients. The MR images and clinical charts of patients with a Baker's cyst were reviewed. None of the 25 patients with a Baker's cyst had an associated anterior cruciate ligament tear or meniscal tear. Two patients had osteochondritis dissecans and two others had synovial disease (infection and juvenile rheumatoid arthritis). Joint fluid was demonstrated in 16 % (4/25) of patients with a Baker's cyst. There was no statistically significant association between presence of a Baker's cyst and presence of joint fluid. Conclusions. Baker's cyst is less prevalent in a paediatric orthopaedic population than in an adult population. In children, it seems that Baker's cyst is seldom associated with joint fluid, meniscal tear, or anterior cruciate ligament tear. On MR images, a communication between the Baker's cyst and the joint was not demonstrated in any of the patients. In addition, the presence of debris and cyst leakage was not observed. (orig.)

    Full Text Available Dentigerous cyst is an odontogenic cyst that surrounds the crown of an impacted tooth, caused by fluid accumulation between the reduced enamel epithelium and the enamel surface, usually associated with mandibular third molars. The purpose of this study was to find out the prevalence of dentigerous cyst caused by impaction of mandibular third molar at the oral and maxillofacial surgery department of Hasan Sadikin hospital Bandung. This study was a descriptive survey study. Samples were taken from the data of patient’s medical record from July 2006 until June 2011. The result of this study showed the number of oromaxillofacial cyst cases in the period was as much as 316 (0.78%. Dentigerous cyst was the most common odontogenic cyst (48,64%. Dentigerous cyst most commonly caused by impaction of the mandibular third molar (13,89%. The amount of male and female patients with dentigerous cyst was the same (50% each. The most age group that suffered dentigerous cyst due to impaction of the mandibular third molars was the age group of 41-50 years (40%. The most chosen therapy was enucleation (100%. From the results of this study can be concluded that dentigerous cyst due to impaction of mandibular third molars was the most common case, with the same frequency found in both male and female, the most age group of impacted was the age group of 41-50 years old, and the most chosen therapy was enucleation.

    Although subpleural cysts are known to be associated with Down syndrome, their etiology and prevalence remains unknown. To determine the prevalence of subpleural cysts in children with Down syndrome and the association with prematurity, congenital heart disease (CHD), extracorporeal membrane oxygenation (ECMO), and chronic ventilator support. A review of the CT examinations of 25 children with Down syndrome was performed to determine the presence, location, and distribution of cysts along with associated abnormalities. Charts were reviewed and coexistent diagnoses and past treatments were recorded. The prevalence of subpleural cysts was 36% with no significant association with CHD, ECMO, or chronic ventilator support. An association was found in the two children with a history of prematurity. The cysts were most commonly found in the anteromedial portion of the lung. Subpleural cysts are common in Down syndrome and should not be confused with another pathological process. An association with prematurity was found, but the low number of children in this study makes the connection uncertain. The etiology remains unclear, but it has been hypothesized that the cysts are associated with lung hypoplasia. (orig.)

    Background: To evaluate the prevalence and characteristics of paratracheal air cysts and their association with emphysema and gender in a general population using low-dose computed tomography scanning of the chest. Materials and methods: We retrospectively enrolled a total of 924 patients (584 women, 340 men; mean age, 59.73 years; range, 37–89 years) who had received low-dose computed tomography scanning for health examination during the period January 1, 2010 to June 30, 2010. Computed tomographic images were evaluated for the presence of paratracheal air cysts. If paratracheal air cysts were identified, the lungs were reconstructed as a three-dimensional model on a commercial workstation. An emphysema index, an objective quantification of the extent of emphysematous changes on CT imaging, was defined as the percentage area of lung with attenuation values below −950 Hounsfield units. Results: A total of 60 patients with paratracheal air cysts were included in this study (estimated prevalence, 6.5%; 12 men, 48 women; mean age, 59.85; range 45–89 years). Emphysema index differed significantly between genders (P < 0.0001). The prevalence of paratracheal air cysts in men was significantly lower than that in women (P = 0.005); however, the emphysema index in patients of both genders showed no evidence of emphysema. The majority (95%) of paratracheal air cysts were at the level of the seventh cervical to the second thoracic vertebrae. Conclusion: The presence of paratracheal air cysts is a common condition in general populations and should not be misdiagnosed as abnormal paratracheal free air. Paratracheal air cysts are more common in woman than in man. In our study, there is no patient with paratracheal air cysts has CT evidence of emphysema.

    The bloom-forming dinoflagellate Alexandrium fundyense has been extensively studied due its toxin-producing capabilities and consequent impacts to human health and economies. This study investigated the prevalence of resting cysts of A. fundyense in western Greenland and Iceland to assess the historical presence and magnitude of bloom populations in the region, and to characterize environmental conditions during summer, when bloom development may occur. Analysis of sediments collected from these locations showed that Alexandrium cysts were present at low to moderate densities in most areas surveyed, with highest densities observed in western Iceland. Additionally, laboratory experiments were conducted on clonal cultures established from isolated cysts or vegetative cells from Greenland, Iceland, and the Chukchi Sea (near Alaska) to examine the effects of photoperiod interval and irradiance levels on growth. Growth rates in response to the experimental treatments varied among isolates, but were generally highest under conditions that included both the shortest photoperiod interval (16h:8h light:dark) and higher irradiance levels (~146-366 μmol photons m -2 s -1 ), followed by growth under an extended photoperiod interval and low irradiance level (~37 μmol photons m -2 s -1 ). Based on field and laboratory data, we hypothesize that blooms in Greenland are primarily derived from advected Alexandrium populations, as low bottom temperatures and limited light availability would likely preclude in situ bloom development. In contrast, the bays and fjords in Iceland may provide more favorable habitat for germling cell survival and growth, and therefore may support indigenous, self-seeding blooms.

    A survey on the prevalence of intestinal protozoan cysts was conductcd in Jeonlanam Do (Province), Korea in 1981. A total of 4,116 specimens was collected from 2,035 male and 2,086 female inhabitants in 4 urban and 7 rural areas. Each case was selected randomly to represent 1,000 inhabitants referred to the census in 1980. Formalin-Ether sedimentation technique was employed to concentrate the cysts and one Lugol's iodine stained smear was examined for each case. The results were summarized as follows: 1. The cases who passed out protozoan cysts of any kind were 9.1 % out of total 4,116 examined, and cumulative positive rate was 11.0 %. Among the positive cases, 16.5 % were infected by two or more species of protozoa. 2. Total 5 species of cysts were detected and the positive rates were as follows; Entamoeba histolytica 1.4 %, E. Coli, 4.9 %, Endolimax nana 2.5 %, Iodamoeba butschlii 0.4 % and Giardia lamblia 1.9 %. 3. The cyst positive rates varied greatly by the surveyed area. The positive rate in rural area was 11.6 % compared with 5.7 % in urban area. The highest rate was found 14.5 % in Gurye Gun (County) and the lowest 3.6 % in Mogpo Si (City). 4. Female showed much higher positive rate than male as 11.8 % compared with 6.4 % and the cumulative rate 14.2 % and 7.6 % respectively. By age group, the rate was highest as 13.9 % in 40~49 years and next 12.5 % in over 60 years group. The cyst prevalence rate diminished remarkably in Jeonlanam Do compared to previous records. However, the finding that 20.2 % of females of 40 years were the carrier of protozoan cysts was an important information in public health point of view.

    Full Text Available Objective To determine the prevalence of liver cysts and hemangiomas in the general population and in cirrhotic patients. Materials and Methods Retrospective, observational, and cross-sectional study selecting consecutive magnetic resonance imaging studies performed in the period from February to July 2011. A total of 303 patients (187 women and 116 men with mean age of 53.3 years were included in the present study. Patients with previously known liver lesions were excluded. The images were consensually analyzed by two observers in the search for simple liver cysts and typical liver hemangiomas, according to universally accepted imaging criteria. Lesions prevalence, diameters and location were determined in both cirrhotic and non-cirrhotic individuals. Results The authors observed prevalence of 8.6% for hemangiomas and 14.5% for simple cysts. No statistically significant difference was observed in relation to prevalence of hemangiomas and cysts among cirrhotic and non-cirrhotic patients (p = 0.954; p = 0.472. Conclusion In the present study, the prevalence of cysts and hemangiomas was higher than the prevalence reported by autopsy series. No influence of cirrhosis was observed on the prevalence and appearance of such incidental lesions.

    Cystic echinococcosis is one of the most widespread zoonoses, causing morbidity and mortality in humans and huge economic losses in livestock. It is caused by metacestodes of the tapeworm Echinococcus granulosus. The metacestodes cause hydatid cysts in the lungs, liver and other organs of intermediate hosts. A study was made from December 2010 through March 2011 to determine the prevalence, organ distribution and characteristics of hydatid cysts in cattle slaughtered at Shashemanne Municipal Abattoir in Oromia, Ethiopia. Antemortem examination of 384 cattle was followed by standard postmortem inspection of their internal organs including lungs, liver, kidneys, spleen and heart for the presence of hydatid cysts. The overall prevalence of hydatid cysts recorded in cattle slaughtered at Shashemanne Municipal Abattoir was 49.5% (190/384). Hydatid cyst prevalence was significantly higher in cattle more than 7 years old compared with those aged 7 years or less, in male cattle compared with female cattle (51.9% vs 31.9%), and in cattle with a body condition score of lean or medium rather than fat (54.05% and 83.2% vs 22.9%). The greatest proportions of cysts were recorded in the lungs (71.6%) and liver (24.1%). Lungs and liver were more commonly infected (95.5%) than other organs. Of the cysts recorded, 15.9% were fertile, 71.7% sterile and 12.2% calcified. The percentage of fertile cysts in the lungs was higher than that in any other organ. Our study showed widespread occurrence of cystic echinococcosis in cattle, which may have a role in the lifecycle of this serious zoonosis.

    Purpose To evaluate the rate of malignancy in incidentally detected simple adnexal cysts at computed tomography (CT) to determine if simple-appearing cysts require follow-up. Materials and Methods In this HIPAA-compliant, institutional review board-approved retrospective cohort study, an institutional database was searched for abdominal and pelvic CT studies performed between June 2003 and December 2010 in women reported to have adnexal cysts. Adnexal cyst characterization was determined by prospective report description as well as image review by a research fellow and by a fellowship-trained abdominal radiologist for examinations with disagreement between the original report and the research fellow's assessment. Patients with known ovarian cysts or ovarian cancer at time of the index CT examination were excluded. Clinical outcome was assessed by using follow-up imaging studies, medical records, and the state cancer registry. Benign outcome was determined by benign findings at surgery, a decrease in size or resolution of a simple-appearing cyst at follow-up imaging, or stability of the cyst for at least 1 year. Descriptive statistics and 95% confidence intervals (CIs) were calculated. Results Among 42 111 women who underwent abdominal and pelvic CT examinations in the study period, 2763 (6.6%; 95% CI: 6.3%, 6.8%) (mean age, 48.1 years ± 18.1; range, 15-102 years) had a newly detected finding of ovarian cyst described in the body or impression section of the report. Median cyst size was 3.1 cm (range, 0.8-20.0 cm). Eighteen (0.7%; 95% CI: 0.4%, 1.0%) of 2763 patients were found to have ovarian cancer after an average follow-up of 5.1 years ± 3.8 (range, 0-12.8 years). None (95% CI: 0%, 0.4%) of 1031 women with simple-appearing cysts were given a diagnosis of ovarian cancer. This included none (95% CI: 0%, 0.4%) of 904 women with simple-appearing cysts with an adequate reference standard for benign outcome. Conclusion The prevalence of previously unknown adnexal

    Full Text Available Giardia duodenalis, Cryptosporidium spp. and Toxoplasma gondii are protozoan parasites that have been highlighted as emerging foodborne pathogens by the Food and Agriculture Organization of the United Nations and the World Health Organization. According to the European Food Safety Authority, 4786 foodborne and waterborne outbreaks were reported in Europe in 2016, of which 0.4% were attributed to parasites including Cryptosporidium, Giardia and Trichinella. Until 2016, no standardized methods were available to detect Giardia, Cryptosporidium and Toxoplasma (oocysts in food. Therefore, no regulation exists regarding these biohazards. Nevertheless, considering their low infective dose, ingestion of foodstuffs contaminated by low quantities of these three parasites can lead to human infection. To evaluate the risk of protozoan parasites in food, efforts must be made towards exposure assessment to estimate the contamination along the food chain, from raw products to consumers. This requires determining: (i the occurrence of infective protozoan (oocysts in foods, and (ii the efficacy of control measures to eliminate this contamination. In order to conduct such assessments, methods for identification of viable (i.e. live and infective parasites are required. This review describes the methods currently available to evaluate infectivity and viability of G. duodenalis cysts, Cryptosporidium spp. and T. gondii oocysts, and their potential for application in exposure assessment to determine the presence of the infective protozoa and/or to characterize the efficacy of control measures. Advantages and limits of each method are highlighted and an analytical strategy is proposed to assess exposure to these protozoa.

    Full Text Available The objectives of this study are to investigate the prevalence of Baker’s cyst (BC in patients with knee pain, and to assess the correlation between BC and severity of osteophytes and joint effusion. A retrospective study was conducted on a group of patients with knee pain referred to our outpatient clinic for ultrasonography of the knee between January 2010 and February 2011. Patients underwent an ultrasonographic exam of the knees to assess the presence of marginal femorotibial osteophytosis, joint effusion and BC. A dichotomous score was assigned to each item (1 present, 0 absent and severity of US signs of osteoarthritis and joint effusion were also graded semiquantitatively. Collected data were processed using logistic regression analysis to evaluate the correlation between degree of osteophytosis and joint effusion and BC. Patients affected by inflammatory joint conditions or with history of joint surgery or recent trauma were excluded. A total of 399 patients with knee pain were studied (299 women, in the age range 18-89 years (mean 56.2, SD 16.3 years. 293 patients (73.4% showed sonographic features of osteoarthritis and 251 (62.9% joint effusion. BC was found in 102 patients (25.8% together with a positive association with sonographic features of osteoarthritis and joint effusion. Our data show a prevalence of BC of 25.8% in a population of patients with knee pain, and suggest that BC is positively related to osteoarthritis and joint effusion. Ultrasonographic examination of knee is worthwhile in patients with painful osteoarthritis or evidence of effusion.

    Full text: In patients referred for PET assessment of myocardial viability on clinical grounds, qualitative and polar map analysis of 13 N ammonia blood flow and 18 F-fluorodeoxyglucose metabolic studies was performed to determine the prevalence and extent of hibernating myocardium. Positron emission tomography studies were acquired in 40 consecutive patients, 36 men and four women (mean age 59 y: range 39-81) over a six-month period to February 1995.The left ventricle was segmented into the three vascular territories and apex. Two independent blinded observers interpreted each myocardial segment for the presence of perfusion metabolism match or mismatch. Mismatched defects were assigned a score to reflect the extent of the abnormality (mild, moderate or severe). Discordant readings were resolved by a third observer. The inter-observer agreement was high (150/160 segments). The observers identified 14 mismatches (11 patients), agreeing on their presence in eleven and extent in eight. In no mismatched segment was disagreement >1 grade. Following resolution of discordant readings, there were eight mild and six moderate mismatches (9 LCx, 3 RCA, 2 Apex). In only two patients was more than one segment involved and moderate mismatches were present in five patients. The frequency of moderate mismatched metabolic abnormalities in this series is lower than previously described. This may reflect enhanced detection of hibernating myocardium using thallium imaging protocols optimised for viability

    Intratesticular cysts, once thought to be a rarity, are now being reported with an increasing prevalence as a result of the wider use of scrotal ultrasound scanning. Despite greater understanding of intratesticular cysts, their management remains unclear. Treatment has included enucleation and even radical orchiectomy over fear of the possibility of an associated malignancy. A more conservative approach with serial ultrasound scanning has been advocated if a clear distinction can be made between neoplastic and non-neoplastic testicular cysts. However, in view of the benign nature of such cysts, even repeated ultrasound scanning may not be necessary and may be considered over-treatment. In this study we present clinical and morphological characteristics of multiple cysts in the right testicle in a 62-year-old patient, where a slightly nodular lesion in the right testicle was detected.

    Highlights: •Secretin improved visualization of ductal communication of a cystic pancreatic lesion. •No association between cysts and gender, ethnicity or type of high risk. •Incremental value of secretin could offset the added cost and time. -- Abstract: Purpose: We investigated the incremental diagnostic yield of S-MRCP in a population with high prevalence of small pancreatic cysts. Methods: Standard MRCP protocol was performed with and without secretin using 1.5 T units in subjects undergoing pancreatic screening because of a strong family history of pancreatic cancer as part of the multicenter Cancer of the Pancreas Screening-3 trial (CAPS 3). All studies were reviewed prospectively by two independent readers who recorded the presence and number of pancreatic cysts, the presence of visualized ductal communication before and after secretin, and the degree of confidence in the diagnoses. Result: Of 202 individuals enrolled (mean age 56 years, 46% males), 93 (46%) had pancreatic cysts detected by MRCP, and 64 of the 93 had pre-and post-secretin MRCP images available for comparison. Data from the 128 readings show that 6 (6/128 = 4.7%) had ductal communication visualized only on the secretin studies compared to pre-secretin studies (odds ratio 1.28, p = 0.04). In addition, there was a statistically significant increase in confidence in reporting ductal communication after secretin compared to before secretin (p < 0.0005). Conclusion: At 1.5 T MRI, the use of secretin can improve the visualization of ductal communication of cystic pancreatic lesions.

    Cystic kidney diseases is a heterogeneous group of developmental, hereditary and acquired disorders that result in the occurrence of one or more cysts on one or both kidneys, and are relatively common. Cystic kidneys can also occur as one of various syndromes of malformations. Kidney cysts can have several classifications, depending on the properties taken in consideration. Some patients remain symptom free for life, whereas others develop serious clinical symptoms that may sometimes be life threatening. It is important to keep in mind the existing classifications, differentiate their succession, clinical course, treatment and prognosis, as well as potential complications. The objective of this paper is to present the most prevalent types of cysts with accompanying clinical symptoms and point out their importance, prevalence and possible association with other serious medical conditions.

    To determine prevalence of complex liver cysts in Autosomal Dominant Polycystic Kidney Disease (ADPKD). Abdominal MRI in 186 ADPKD subjects were evaluated by two independent observers to determine prevalence of complex liver cysts. 23 (12%) of subjects, had at least 1 complex cyst. Only 8 (4%) were reported to have a complex cyst prospectively, representing an under-reporting rate of 65%. Median total cyst volume was 66-times greater for subjects with complex cysts compared to subjects without (p<0.0001). Complex hepatic cysts were observed in 12% of ADPKD cases, occurring more frequently in livers with extensive cystic involvement. Copyright © 2017 Elsevier Inc. All rights reserved.

    Epidermoid cysts represent the most common cutaneous cysts. They are usually small and benign; however, sometimes they can grow to giant epidermoid cists, and occasionally malignancies develop. Giant epidermoid cysts at the earlobe have never been described but in other locations. We describe a case of a giant epidermoid cyst at the earlobe, a location where such a large cyst has never been reported before. The mass was completely resected and the wound of the pedunculated base was sutured with four stitches of nylon 5/0. Histopathology confirmed the presumptive diagnosis of an epidermoid cyst. Six months after the resection, the patient did not have any relapse of the epidermoid cyst. The earlobe is a potential location for giant epidermoid cysts. Although the clinical diagnosis could be enough, due to the possibility of malignancy and to ensure appropriate diagnosis, we consider that all cysts should be sent to the anatomic pathology laboratory for histological evaluation.

    Full Text Available Back ground: Aneurysmal bone cysts have raised intra-cystic pressures which are dynamic and diagnostic in nature. Aneurysmal bone cysts could be diagnosed from other benign cystic lesions of bone by recording their intra-cystic pressures with a spinal manometer. Raised intra-cystic pressures in aneurysmal bone cysts are maintained as long as the periosteum over the cyst is intact even in those with pathological fractures. Even though its pathology is definite its aetio-pathology is not clear Method: Fourteen out of 16 radiologically benign cystic lesions of bone were subjected to intra-cystic pressure recordings with spinal manometer. Other two cysts had displaced unimpacted pathological fractures and so their intra-cystic pressures could not be recorded. All 16 cysts were subjected to histo-pathological examination to confirm their diagnosis and to find out for any pre-existing benign pathology. All the cysts were surgically treated. Results: Fourteen benign cystic lesions of bone were diagnosed as aneurysmal bone cysts preoperatively by recording raised intra-cystic pressures and confirmed by histo-pathology. In addition, histo-pathology revealed pre-existing benign pathology. All cysts were successfully treated surgically. Conclusions: Since, there is appreciable rise in intra-cystic dynamic pressures, the aneurysmal bone cyst is considered to be due to either sudden venous obstruction or arterio-venous shunt. Pre-operative intra-cystic pressure recordings help not only to diagnose aneurysmal bone cysts but also to assess the quantum of blood loss and its replacement during surgery.

    Cysts of spleen are rare entities. Congenital splenic cysts are even more uncommon comprising of only 10% of benign non-parasitic cysts. We report a case of 22 years old female who presented with history of 2 years abdominal pain and gradual distension. Ultrasound and computed tomography (CT) both were suggestive of splenic cyst. Laboratory tests show thrombocytopenia with platelets count of 97000 per cubic millimeter and anemia with hemoglobin 8.7 gram per deciliter. Serological tests were negative for parasitic infection. Splenectomy was done and the weight of the spleen was found to be 1.5 kilogram. Histopathological findings are consistent with splenic epithelial cyst. The aetiology, diagnostic modalities and treatment options are discussed in the case report. (author)

    2017-07-01

    We systematically evaluated the Bosniak classification system with malignancy rates of each Bosniak category, and assessed the effectiveness related to surgical treatment and oncologic outcome based on recurrence and/or metastasis. In a systematic review according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies) criteria, we selected 39 publications for inclusion in this analysis and categorized them into 1) surgical cohorts-all cysts treated surgically and 2) radiological cohorts-cysts with surgical treatment or radiological followup. A total of 3,036 complex renal cysts were categorized into Bosniak II, IIF, III and IV. In surgical and radiological cohorts pooled estimates showed a malignancy prevalence of 0.51 (0.44, 0.58) in Bosniak III and 0.89 (0.83, 0.92) in Bosniak IV cysts, respectively. Stable Bosniak IIF cysts showed a malignancy rate of less than 1% during radiological followup (surveillance). Bosniak IIF cysts, which showed reclassification to the Bosniak III/IV category during radiological followup (12%), showed malignancy in 85%, comparable to Bosniak IV cysts. The estimated surgical number needed to treat to avoid metastatic disease of Bosniak III and IV cysts was 140 and 40, respectively. The effectiveness of the Bosniak classification system for complex renal cysts was high in categories II, IIF and IV, but low in category III, and 49% of Bosniak III cysts was overtreated because of a benign outcome. This surgical overtreatment combined with the excellent outcome for Bosniak III cysts may suggest that surveillance is a rational alternative to surgery. This will require further study to assess whether surveillance of Bosniak III cysts will prove safe. Copyright © 2017 American Urological Association Education and Research, Inc.

Transthoracic echocardiography revealed a large, round cystic lesion with multiple daughter cysts without any obvious intraluminal detached membranes with mass effect on the left ventricular outflow tract. After total excision, residual tissue was closed with Teflon patch. Germinative membrane and hundreds of daughter cysts were seen. Following total excision of the cyst from myocardium, myocardial cavity was washed thoroughly with 10% Betadine solution. Pathological examination confirmed the diagnosis of hydatid cyst. Preoperatively started albendazole was continued for 4 weeks even after the operation. On follow-up after 4 weeks, the patient is doing well and cardiac imaging showed normal contours of the heart.

    Pineal cysts are common incidental findings in children undergoing magnetic resonance imaging (MRI). Several studies have suggested MRI follow-up if the cyst is larger than 10 mm. However, cysts do not usually change during follow-up. Prevalence, growth, and structure of the pineal cysts were analyzed to decide if follow-up MRI is necessary. A retrospective review between 2010 and 2015 was performed using 3851 MRI examinations of children aged 0-16 years to detect pineal cysts having a maximum diameter ≥ 10 mm. Eighty-one children with pineal cysts were identified and 79 of them had been controlled by MRI. Cysts were analyzed for the size, growth, and structure. A total of 1.8% of the children had a pineal cyst with a diameter ≥ 10 mm. Cysts were present in 48 girls (59.3%) and 33 boys (40.7%). Most pineal cysts (70/79) did not significantly grow during the follow-up (median 10 months, range 3-145 months). A total of 11.4% (9/79) of the cysts grew with the biggest change measured from the outer cyst wall sagittal anteroposterior dimension (mean 3.4 mm ± 1.7 mm). Only one cyst grew more than 5 mm. We found no factors correlating with the cyst growth among 9 cysts that grew > 2 mm. A majority of pineal cysts remained unchanged during the MRI follow-up. Results of this study suggest that routine MRI follow-up of pineal cysts is not necessary in the absence of unusual radiological characteristics or related clinical symptoms. (orig.)

    Authors described a case of 60 year-old woman with multiple lateral neck cysts. 4 cysts were located in the supraclavicular region of lateral neck triangle. During histopathological studies of postoperative specimens a cystic hygroma diagnosis was established. The fact, that cystic lymphangioma occurred in an adult woman, was interesting. The authors stress the necessity of preoperative evaluation of tumor size in view of the possibility of its penetration into the thorax. The CT examination may be useful in these cases. (author)

    Gingival cyst of newborn is an oral mucosal lesion of transient nature. Although it is very common lesion within 3 to 6 weeks of birth, it is very rare to visualize the lesion thereafter. Presented here is a case report of gingival cyst, which was visible just after 15 days of birth. Clinical diagnoses of these conditions are important in order to avoid unnecessary therapeutic procedure and provide suitable information to parents about the nature of the lesion.

    The production of viable cysts by Giardia is essential for its survival in the environment and for spreading the infection via contaminated food and water. The hallmark of cyst production (also known as encystation) is the biogenesis of encystation-specific vesicles (ESVs) that transport cyst wall proteins to the plasma membrane of the trophozoite before laying down the protective cyst wall. However, the molecules that regulate ESV biogenesis and maintain cyst viability have never before been identified. Here, we report that giardial glucosylceramide transferase-1 (gGlcT1), an enzyme of sphingolipid biosynthesis, plays a key role in ESV biogenesis and maintaining cyst viability. We find that overexpression of this enzyme induced the formation of aggregated/enlarged ESVs and generated clustered cysts with reduced viability. The silencing of gGlcT1 synthesis by antisense morpholino oligonucleotide abolished ESV production and generated mostly nonviable cysts. Interestingly, when gGlcT1-overexpressed Giardia was transfected with anti-gGlcT1 morpholino, the enzyme activity, vesicle biogenesis, and cyst viability returned to normal, suggesting that the regulated expression of gGlcT1 is important for encystation and viable cyst production. Furthermore, the overexpression of gGlcT1 increased the influx of membrane lipids and fatty acids without altering the fluidity of plasma membranes, indicating that the expression of gGlcT1 activity is linked to lipid internalization and maintaining the overall lipid balance in this parasite. Taken together, our results suggest that gGlcT1 is a key player of ESV biogenesis and cyst viability and therefore could be targeted for developing new anti-giardial therapies.

    Full Text Available Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of retroperitoneal bronchogenic cysts written in English. Anatomopathological criteria for inclusion were pseudo stratified, ciliated, columnar epithelium together with the presence of at least one of the following: cartilage, smooth muscle or seromucous glands. In addition, the embryology, pathogenesis, radiological, clinical and suggested treatment modalities are reviewed. We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a non-functioning left adrenal mass. Our review of literature revealed only 62 potential cases of retroperitoneal bronchogenic cysts. After applying the strict anatomopathological criteria, only 30 cases of true retroperitoneal bronchogenic cysts could be identified. Retroperitoneal location of a bronchogenic cyst is rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Only histology can confirm definitive diagnosis. Surgery remains the recommended treatment of choice.

    Choroidal fissure cysts are often incidentally discovered. They are usually asymptomatic. The authors report a case of growing and hemorrhagic choroidal fissure cyst which was treated surgically. A 22-year-old female presented with headache. Cranial MRI showed a left-sided choroidal fissure cyst. Follow-up MRI showed that the size of the cyst had increased gradually. Twenty months later, the patient was admitted to our emergency department with severe headache. MRI and CT showed an intracystic hematoma. Although such cysts usually have a benign course without symptoms and progression, they may rarely present with intracystic hemorrhage, enlargement of the cyst and increasing symptomatology.

    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. (author)

    Full Text Available Dentigerous cysts are the most common bony lesions of the jaws in children. It is one of the most prevalent types of odontogenic cysts associated with an erupted or developing tooth, particularly the mandibular third molars; the other teeth that are commonly affected are, in order of frequency, the maxillary canines, the maxillary third molars, and rarely the central incisors. Radiographically, the cyst appears as ovoid well-demarcated unilocular radiolucency with a sclerotic border. Careful evaluation of the history and the clinical and radiographical findings help clinicians to currently diagnose the condition, identify the etiological factors, and administer the appropriate treatment.

    Acanthamoeba cysts are highly resistant to contact lens disinfecting solutions. Acanthamoeba cyst wall is partially made of 1,4 β-glucan (i.e., cellulose) and other complex polysaccharides making it a hardy shell that protects the resident amoeba. Here, we hypothesize that targeting the cyst wall structure in addition to antiamoebic compound would improve the efficacy of marketed contact lens disinfecting solutions. Using chlorhexidine as an antiamoebic compound and cellulase enzyme to disrupt cyst wall structure, the findings revealed that combination of both agents abolished viability of Acanthamoeba castellanii cysts and trophozoites. When tested alone, none of the agents nor contact lens disinfecting solutions completely destroyed A. castellanii cysts and trophozoites. The absence of cyst wall-degrading enzymes in marketed contact lens disinfecting solutions render them ineffective against Acanthamoeba cysts. It is concluded that the addition of cyst wall degrading molecules in contact lens disinfecting solutions will enhance their efficacy in decreasing the incidence of Acanthamoeba effectively.

    2011-05-01

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    To (1) synthesize the terminology used to classify extramedullary spinal cysts in dogs to clarify some of the commonly reported misconceptions, and (2) propose a classification scheme to limit confusion with terminology. Literature review. An online bibliographic search was performed in January 2013 for articles relating to extramedullary spinal cysts in dogs using PubMed (http://www.pubmed.gov/) and Google Scholar (http://scholar.google.com/) databases. Only peer-reviewed clinical literature describing cystic lesions pertaining to the spinal cord and associated structures was included. From 1962 to 2013, 42 articles were identified; 25 (95 dogs) reported meningeal cysts, 10 (24 dogs) described 60 extradural cysts, 3 reports (18 dogs) described discal cysts or acute compressive hydrated nucleus pulposus extrusions (HNPE). Spinal cysts were categorized by location based on cross-sectional imaging as meningeal or extradural non-meningeal. Sub-classification was then performed based on surgical findings and pathology. Meningeal cysts included arachnoid diverticulae and Tarlov (perineural) cysts. Extradural non-meningeal cysts included intraspinal cysts of the vertebral joints, ligaments and discs. Discal cysts also fit this category and have been reported extensively in humans but appear rare in dogs. Extramedullary spinal cysts should be first classified according to location with a sub-classification according to pathologic and surgical findings. Previous canine cases of discal cysts appear to represent a different disease entity and the term acute compressive HNPE is therefore preferred. © Copyright 2014 by The American College of Veterinary Surgeons.

    Subchondral cysts have always been taught to be one of the cardinal radiological features of knee osteoarthritis but are not well understood. We aimed to evaluate the radiological prevalence and epidemiology of subchondral cysts in patients with knee osteoarthritis to determine if they are truly a cardinal radiological feature. All patients of a single surgeon with symptoms of knee osteoarthritis were selected for this study. All patients had failed a trial of conservative therapy and were planned for total knee arthroplasty. Patients with symptoms of and documentary evidence of inflammatory arthritis, other neurological and orthopaedic problems causing functional deficits were excluded from this study. A total of 806 plain radiographs were analyzed with the aid of an atlas for the presence of narrowed joint space, osteophytes, subchondral sclerosis and subchondral cysts. The radiological prevalence of each feature was then calculated. Demographics and pre-operative measurements were compared between patients with and without radiological evidence of subchondral cysts. Subchondral cysts were only present in 30.6% of the study population. Narrowed joint space was present in 99.5%, osteophytes in 98.1% and subchondral sclerosis in 88.3% of all radiographs. The differences in prevalence were statistically significant. There was a higher proportion of females in patients with radiological evidence of subchondral cysts. These patients also had a greater varus deformity preoperatively. With a radiological prevalence of 30.6%, subchondral cysts should not be considered a cardinal radiological feature of osteoarthritis. Subchondral cysts may be associated with the female gender and genu varum.

    Many pathological causes are responsible for the sonographic presentation of myometrium cysts and cyst-like lesions, where the distinction between these etiologies is required. The current work is aimed at discerning between different etiologies of myometrium cysts and cyst-like lesions for an optimum management. In the course of daily practice of gynecological transvaginal ultrasound, 66 cases of myometrium cysts and cyst-like lesions have been discerned, where all were examined with endovaginal ultrasound using a multifrequency endocavitary probe having color Doppler capability. Adenomyosis uteri detected in 15 cases, invasive mole in 4 cases, congested arcuate veins in 20 cases, incidental cysts in 4 cases, cystic degeneration of myoma in 3 cases, C-section scar cysts and cyst-like lesions in 13 cases, interstitial ectopic pregnancy in 2 cases, incomplete abortion with congested myometrium vessels in 4 cases, and arteriovenous malformation in 1 case. The number of cases with cervical nabothian cysts was not considered since they were too frequent. Endosonography is an important tool in differentiating between the various diseases that are responsible for benign myometrium cysts and cyst-like lesions, which are all important since some of them are visualized as serious clinical situations and others turn out to be of little clinical significance.

    Full Text Available Second branchial cleft cysts are almost always located in the neck; thus, their presence in the nasopharynx is extremely rare. A 44-year-old man was referred to our department because a cystic mass was fortuitously found in the right lateral nasopharyngeal wall during transnasal esophagogastroscopy. He had suffered from intermittent right-sided nasal obstruction since childhood. T1- and T2-weighted magnetic resonance imaging revealed hyperintense signals. Marsupialization was performed by diode laser via an endoscopy-guided approach. No immediate postoperative complications occurred, and there was no recurrence 6 months following surgery. When a cystic lesion presents in the lateral nasopharynx, branchial cleft cyst should be considered in the differential diagnosis. In our experience, marsupialization by diode laser via an endoscopy approach is a safe and straightforward method of treating nasopharyngeal branchial cleft cyst, with no adverse effects.

    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.

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

    The purpose of this study is to differentiate endometrial cysts from hemorrhagic cysts on the basis of MR findings. The MR findings of twelve patients with endometrial cysts (15 cases) and of nine patients with hemorrhagic cyst (12 cases) were retrospectively evaluated. Fourteen patients were surgically confirmed and seven with hemorrhagic cysts were clinically diagnosed by resolution of the cysts during ultrasound follow up. Sixteen patients underwent MR imaging using a 1.5T system (Magnetom Vision, Siemens, Germany), and for five patients a 2.0 T system (Spectro 2000, Goldstar, Korea) was used. MR images were retrospectively evaluate with respect to size and signal intensity of the cyst, uni/multilocularity, shading, the hematocrit effect, clot fluid-fluid level and septum, and thickness, signal intensity and enhancement of the cyst wall. Uni/multilocularity, septum, and signal intensity and enhancement of the cyst wall were useful for the differentiation of endometrial from hemorrhagic cysts. Signal intensity of the cyst, shading, the hematocrit effect and clot were not helpful. (author). 20 refs., 3 tabs., 5 figs

    We report an extremely rare case of an epidermoid cyst in the kidney of a 74-year-old man who had presented with painless hematuria. Radiologic examination revealed a cyst in the kidney that was thought to be neoplastic. The patient underwent surgery to remove the cyst, and we received the nephrectomy specimen. A 6-cm cyst with no solid areas was seen. On histologic examination, this was an epidermoid cyst. We reviewed the published data and discuss the possible theories of origin of this rare condition.

    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.

    The purpose of this study was to review the MRI criteria for the distinction of meniscal cysts from other cystic lesions in the knee so that appropriate treatment may be planned. A retrospective review of 62 knee MRI scans possibly showing meniscal cysts was performed. The type of meniscal tear, the appearance of the connection between the cyst and the meniscal tear, and the location, size, morphology, and signal characteristics of the meniscal cysts were recorded. Other types of fluid collections that had been mistaken for meniscal cysts were described. MRI can be used to distinguish meniscal cysts from other fluid collections that may mimic meniscal cysts. Pitfalls can be avoided by familiarity with the normal bursal and capsular anatomy, and by the application of the specific diagnostic criteria. (orig.)

  11. Assessment of myocardial viability.

    Travin, Mark I; Bergmann, Steven R

    2005-01-01

    The prevalence of left ventricular (LV) dysfunction and resultant congestive heart failure is increasing. Patients with this condition are at high risk for cardiac death and usually have significant limitations in their lifestyles. Although there have been advances in medical therapy resulting in improved survival and well being, the best and most definitive therapy, when appropriate, is revascularization. In the setting of coronary artery disease, accounting for approximately two thirds of cases of congestive heart failure, LV dysfunction often is not the result of irreversible scar but rather caused by impairment in function and energy use of still viable-myocytes, with the opportunity for improved function if coronary blood flow is restored. Patients with LV dysfunction who have viable myocardium are the patients at highest risk because of the potential for ischemia but at the same time benefit most from revascularization. It is important to identify viable myocardium in these patients, and radionuclide myocardial scintigraphy is an excellent tool for this. Single-photon emission computed tomography perfusion scintigraphy, whether using thallium-201, Tc-99m sestamibi, or Tc-99m tetrofosmin, in stress and/or rest protocols, has consistently been shown to be an effective modality for identifying myocardial viability and guiding appropriate management. Metabolic imaging with positron emission tomography radiotracers frequently adds additional information and is a powerful tool for predicting which patients will have an improved outcome from revascularization, including some patients referred instead for cardiac transplantation. Other noninvasive modalities, such as stress echocardiography, also facilitate the assessment of myocardial viability, but there are advantages and disadvantages compared with the nuclear techniques. Nuclear imaging appears to require fewer viable cells for detection, resulting in a higher sensitivity but a lower specificity than stress

  12. Synovial cyst of the lumbar spine: CT and MR findings

    Vives, Daniel A.; Bauni, Carlos E.; Mendoza, Monica E.

    2000-01-01

    The purpose of this revision article is to show the images of intraspinal synovial cysts, using MR and CT. The synovial cyst is an infrequent entity that predominates in the lower lumbar spine. It shows a prevalence on the L4-L5 level, and is uncommon before the age of 30 years. The cyst communicates with the adjacent apophysial joint, and these joints are frequently altered by osteoarthritis. The simple X-ray and the myelography do not contribute to the diagnosis. The CT and MR are the most accurate methods for this anatomical alteration. The synovial cysts have similar behavior: iso-hypointense in T1 weighted and hyperintense in T2 weighted in the MR examinations and some of them show the classical calcification of their wall in the CT studies.

    2016-01-01

    Fabry disease is an inherited, X-linked lysosomal storage disorder caused by deficiency of the enzyme alpha galactosidase A (alpha-GLA A), which leads to glycosphingolipid accumulation, mainly globotriaosylceramide, in tissues. Disease prevalence and the index of suspicion are both low, which tends to result in delayed diagnosis and treatment. We present the case of a male Fabry disease patient who manifested no angiokeratoma lesions but presented multiple parapelvic cysts and renal failure. The genetic study revealed an alpha-GLA A gene mutation that had not been recorded in the mutations registry. The de novo mutation was not found in his relatives and it was not transmitted to his offspring. The large number and peculiar appearance of the parapelvic cysts led to the diagnosis.

    2015-01-01

    Full Text Available "Hydatid" is a Greek word which means "a drop of water." Hydatid cysts occur in hydatid disease or echinococcosis, which is one of the most geographically prevalent zoonosis. This zoonotic infection in humans is mainly caused by infection by the larval stage of the dog tapeworm Echinococcus granulosus. This tapeworm infestation is widespread in sheep, goats, cattle, and dogs. This chronic disease is present worldwide among herding populations who live in close proximity to dogs and herd animals. It is a serious and potentially fatal condition and symptoms may occur a long time after the early infection. The most frequently affected organs are liver, lungs, followed by bones and brain, and extremely unusual occurrence has been found in the oral cavity, which was noticed in the present case. So hereby, we reveal a very rare case of intraoral hydatid cyst in a 20-year-old female patient.

    We studied 37 intradiploic epidermoid cysts, reviewing typical and atypical radiological features and the differential diagnosis. The most common clinical feature was a long standing lump in the scalp, occurring in 25 patients (67.7 %). Plain films were the most cost-effective radiological technique in diagnosis. The typical finding was a well-defined lytic lesion with sclerotic border, seen in 29 cases (78 %). Atypical lesions were those larger than 5 cm and/or with an ill-defined edge, being observed in 8 cases (22 %). CT and MRI were the best methods for assessing atypical ones. In all cases with typical radiological findings a preoperative diagnosis of intradiploic epidermoid cyst was suggested. (orig.). With 8 figs., 3 tabs

    2015-01-01

    Full Text Available A dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth. Through various cases that have been reported, it is observed that 95% of this cyst is associated with permanent dentition while only 5-6% is in association with supernumerary teeth. Mesiodens, a supernumerary tooth situated between the maxillary central incisors, has a prevalence of 0.15-1.9%. Here, a dentigerous cyst in association with a pair of impacted mesiodens is reported in a 56-year-old female patient.

    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.

    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.

  4. Nonfunctional parathyroid cyst: case report

    Directory of Open Access Journals (Sweden)

    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 Methicillin-resistant Staphylococcus aureus (MRSA is a major nosocomial pathogen worldwide. Malta is one of the countries with the highest MRSA prevalence in Europe, as identified from hospital blood cultures [1]. However, community prevalence of MRSA has never previously been investigated. This study aimed at establishing the prevalence of community MRSA nasal colonization in Maltese individuals and identifying the clonal characteristics of the detected isolates. Nasal swabs were collected from 329 healthy individuals who were also asked to complete a brief questionnaire about risk factors commonly associated with MRSA carriage and infection. The swabs were transported and enriched in a nutrient broth supplemented with NaCl. The presence of MRSA was then determined by culturing on MRSA Select chromogenic agar and then confirming by several assays, including catalase, coagulase and PBP2a agglutination tests. The isolates were assayed for antibiotic susceptibilities and typed by microarray analysis to determine the clonal characteristics of each strain. The prevalence of MRSA nasal colonization in the healthy Maltese population was found to be 8.81% (95% confidence interval [CI], 5.75–11.87%, much higher than that found in other studies carried out in several countries. No statistical association was found between MRSA carriage and demographics or risk factors; however, this was hindered by the small sample size. Almost all the isolates were fusidic-acid resistant. The majority were found to belong to a local endemic clone (CC5 which seems to be replacing the previously prevalent European clone UK-EMRSA-15 in the country. A new clone (CC50-MRSA-V was also characterized. The presence of such a significant community reservoir of MRSA increases the burdens already faced by the local healthcare system to control the MRSA epidemic. Colonization of MRSA in otherwise healthy individuals may represent a risk for endogenous infection and transmission to

    To investigate the prevalence and anatomy features of iridociliary body cysts in patients with narrow anterior chamber angle. Retrospective case series study. The prevalence and anatomy features of iridociliary body cysts in 223 patients (402 eyes) were analyzed retrospectively with ultrasound biomicroscopy (UBM). All of the patients were examined for susceptive narrow anterior chamber angle without complaint. The age of the patients, the site, diameter and number of cysts, the anterior chamber angle and the central anterior chamber depth were measured. Iridociliary body cysts were found in 19 patients (23 eyes) out of 223 patients (402 eyes), the prevalence is 5.7%. Fifteen patients were unilateral and four patients bilateral. Two cases originated from the ciliary process, eighteen cases from the iris root, and three from both the root and posterior surface of the iris. Twenty one cases were single cysts while two cases were multiple cysts. The diameter of the cysts ranged from 0.5 to 3.1 mm, averaged (0.71 ± 0.53) mm. The average age and the central anterior chamber depth of the eyes with iridociliary body cysts were (55.32 ± 10.74) years and (2.25 ± 0.39) mm, with no significant difference (t = 0.534, 0.783; P > 0.05) as compared to that of patients without cysts, which were (57.46 ± 10.52) years and (2.14 ± 0.34) mm. The anterior chamber angle in iridociliary body cysts group was 8.2° (21.0°, 0.0°), with no significant difference (Z = -0.062, P > 0.05) as compared to that of patients without cysts, which was 8.9° (21.4°, 0.0°). The prevalence rate of iridociliary body cysts in this study is 5.7%, central anterior chamber depth and anterior chamber angle in patients with cysts do not differ form patients without cysts.

    Retroareolar cysts present in female adolescents with palpable subareolar masses that can have concomitant inflammatory changes. The purpose of this study was to report our cases of retroareolar cysts and thus to contribute to a better knowledge and understanding of this entity. Forty-six girls were diagnosed with retroareolar cysts between December 2000 and July 2002. A retrospective chart review is presented with the clinical and ultrasonographic findings. Age at presentation was 10 to 20 years. The reason for consultation was acute mastalgia and inflammation in 31 cases and palpable nodule in 15 cases. Two patients had areolar discharge. Ultrasonographic imaging in the 46 girls showed retroareolar simple cysts, either multiple or bilateral. The cysts had thin walls and were round, oval, or elongated with a variable diameter always less than 20 mm. They had liquid content with an echogenic or calcific sediment. When retroareolar cysts presented with inflammatory changes, antibiotics and nonsteroidal anti-inflammatory drugs were used. Inflammatory changes disappeared in approximately seven days. All patients experienced favorable outcomes. Retroareolar cysts are a benign form of breast disease in the adolescent. Further investigation is needed to completely understand the pathophysiology, epidemiology, and natural history of this diagnosis.

    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.

    Craniotomy and an examination of the maximal extent of extirpation of the cystic membrane were performed under an operative microscope in a series of 30 consecutive cases of intracranial arachnoid cysts. From these clinical features and a histological examination of the membrane, the etiologies of the arachnoid cysts may be divided into three fundamental categories: arachnoid cysts due to local brain atrophy or malformation (Category I), arachnoid cysts due to a malformation of the local arachnoid membrane itself (Category II), and arachnoid cysts due to acquired etiology (Category III). The postoperative reduction rates were investigated by means of a serial CT examination over a follow-up period of from 1 month to 6.5 years (average 2 years) in 27 cases. The postoperative reduction rates of 5 cases were less than 20% (Group A), 15 cases had rates from 30 to 80% (Group B), and 7 cases had rates of more than 90% (Group C). Cases of females, large cysts, round-shaped cysts, and cases with positive mass signs and poorly communicating cysts are revealed by metrizamide CT examination seemed to have a tendency for cystic cavity to be reduced well, judging from the postoperative analysis of the clinical findings. Furthermore, from the standpoint of our hypothesis concerning the etiology of the arachnoid cysts, Group A fit in almost all cases in Category I, though a few cases of Group A who had severe secondary local brain damage were in Category II. Group C fit in Category III in almost all cases, though a few cases of Group C who had minimal local brain damage were in Category II. Cases of Group B were considered to show some changes in the local cerebrum of various degrees in the cases of Categories II and III. (J.P.N.)

    On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%), indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases.

    Full Text Available Caroli diseaseis a rare congenital disorder that classically causes saccular dilatation of the bile ducts. The complications of Caroli include choledochal cysts with recurrent cholangitis, abscess formation, septicaemia, intrahepatic lithiasis and amyloidosis.We report a rare case of a young female with Caroli disease pointing out the intrahepatic lithiasis as a rare complication of the disease. Learning points Caroli disease is an uncommon condition that should be considered in the differential diagnosis of hepatic essential cysts. Clinically, it is characterized of recurrent episodes of fever and pain. The correct and early diagnostic is important because of the different complications and treatment unlike the essential hepatic cysts.

    Full Text Available Os cistos de Baker localizam-se na região posteromedial do joelho, entre o ventre medial do músculo gastrocnêmio e o tendão semimembranoso. No adulto, esses cistos estão relacionados a lesões intra-articulares, quais sejam, lesões meniscais ou artrose. Nas crianças, geralmente são achados de exame físico ou de exames de imagem, apresentando pouca relevância clínica. O exame de ultrassonografia é adequado para identificar e mensurar o cisto poplíteo. Para o tratamento, a abordagem principal deve ser relacionada ao tratamento da lesão articular. Na maioria dos casos não há necessidade de se abordar diretamente o cisto. Os cistos no joelho são, quase na sua totalidade, benignos (cistos de Baker e cistos parameniscais. Porém, a presença de alguns sinais demanda que o ortopedista suspeite da possibilidade de malignidade: sintomas desproporcionais ao tamanho do cisto, ausência de lesão articular (ex.: meniscal que justifique a existência do cisto, topografia atípica, erosão óssea associada, tamanho superior a 5cm e invasão tecidual (cápsula articular.Baker's cysts are located in the posteromedial region of the knee between the medial belly of the gastrocnemius muscle and semimembranosus tendon. In adults, these cysts are related to intra-articular lesions, which may consist of meniscal lesions or arthrosis. In children, these cysts are usually found on physical examination or imaging studies, and they generally do not have any clinical relevance. Ultrasound examination is appropriate for identifying and measuring the popliteal cyst. The main treatment approach should focus on the joint lesions, and in most cases there is no need to address the cyst directly. Although almost all knee cysts are benign (Baker's cysts and parameniscal cysts, presence of some signs makes it necessary to suspect malignancy: symptoms disproportionate to the size of the cyst, absence of joint damage (e.g. meniscal tears that might explain the

    2016-01-01

    Full Text Available Odontogenic cysts have a high prevalence in the dental clinic population, with dentigerous cyst being one of the most frequent ones and whose aetiology involves accumulation of fluid between the reduced enamel epithelium and the crown of an unerupted tooth. In the diagnostic process of these lesions, one should consider complementary imaging exams such as conventional radiography and computed tomography, which are commonly used for providing anatomical information on the tissues compromised by the lesion, but not on the nature of it. Magnetic resonance imaging (MRI scans are noninvasive modalities which, due to their unique acquisition characteristics, can provide distinct information on the nature of the lesion. This study reports on a case of dentigerous cyst in the mandible of a 9-year-old patient, documented by means of different imaging modalities. MRI played an important role in both diagnosis of the lesion and differential diagnosis between neoplastic lesions presenting similar imagenological behaviour under other techniques of radiography.

    The prevalence of hepatic cysts is 0.1% to 0.5% based on autopsy studies, and 2.5% based on US examinations. Percutaneous therapies are a new alternative to surgery. They include simple percutaneous aspiration, catheter drainage alone, and catheter drainage with sclerotherapy. We present an 11-year-old boy admitted to hospital because of abdominal pain. A diagnosis of simple hepatic cyst was made, which was treated with aspiration and tetracycline hydrochloride solution (5%) injection into the cystic cavity. Complete regression was seen on US and MRI examination at 3 months, with total collapse and deflation of the cyst. The cyst regressed totally, leaving a hyperechoic linear scar on US examination at 1 year. On the basis of the clinical and imaging results obtained, percutaneous sclerotherapy of hepatic cysts can be recommended as the treatment of choice and as a valid alternative to laparoscopy in children.

    Mesenteric cysts (MC) are benign cystic tumors that grow within mesentery or omentum tissue. We have reviewed the cases of MC reported and operated on in our centre. Retrospective review of clinical records of MC cases during the period 2002-2012 RESULTS: A total of 7 patients were found. Mean age was 5.3 years (range 3-11). Abdominal ultrasound was the diagnostic tool in all cases, except for one, which was diagnosed during laparotomy. All presented abdominal pain, 5 (71.4%) vomiting, 4 (57%) gross abdominal distension, 3 (42.8%) fever, and none presented complete abdominal obstruction, although 2 patients (28.6%) had slight sub-occlusion symptoms. All MC were pedicled or sesil, except for our last case, which extended into the retroperitoneum. All specimens were reported as Limphatic Malformation. None recurred. MC in children are mostly Lymphatic Malformations of mesentery or omentum origin, and clinical presentation varies from chronic abdominal pain to sudden-onset peritonitis or volvulus. About 50-60% require intestinal resection and anastomosis. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    2017-12-01

    The term resilience has become extremely fashionable and there had been many attempts to provide operational definition and in fact metrics going beyond a set of more or less ad-hoc indicators. The viability theory (Aubin and Saint-Pierre, 2011) have been used to give a rather precise mathematical definition of resilience (Deffuant and Gilbert, 2011). However, it does not grasp the multiscale nature of resilience that is rather fundamental as particularly stressed by Folke et al (2010). In this communication, we first recall a preliminary attempt (Tchiguirinskaia et al., 2014) to define multifractal resilience with the help of the maximal probable singularity. Then we extend this multifractal approach to the capture basin of the viability, therefore the resilient basin. Aubin, J P, A. Bayen, and P Saint-Pierre (2011). Viability Theory. New Directions.

    The book is an almost self-contained presentation of the most important concepts and results in viability and invariance. The viability of a set K with respect to a given function (or multi-function) F, defined on it, describes the property that, for each initial data in K, the differential equation (or inclusion) driven by that function or multi-function) to have at least one solution. The invariance of a set K with respect to a function (or multi-function) F, defined on a larger set D, is that property which says that each solution of the differential equation (or inclusion) driven by F and issuing in K remains in K, at least for a short time.The book includes the most important necessary and sufficient conditions for viability starting with Nagumo's Viability Theorem for ordinary differential equations with continuous right-hand sides and continuing with the corresponding extensions either to differential inclusions or to semilinear or even fully nonlinear evolution equations, systems and inclusions.

    Endodermal cysts (EC) of the central nervous system are very uncommon lesions predominantly located in the spinal canal. Although rare, intracranial EC have been mainly described in the posterior fossa, with the supratentorial location considered exceptional. Apart from the low frequency of these lesions, their pathoembriology still remais unknown. We report a patient with a huge frontal EC and review the literature. A 62-year-old man presented with abnormal behaviour, disorientation and decreased level of consciousness after moderate head injury. Initial cranial CT scan revealed a large cyst in the left frontal region with marked midline shift. Emergency puncture and decompression of the cyst demonstrated a milky fluid with high protein levels. Cranial MRI after patient improvement confirmed the existence of the cystic lesion with less mass effect. Delayed surgery was performed with craniotomy and total removal of the cyst. Pathological examination confirmed the presence of a typical EC. Patient made a complete recovery on follow-up with no recurrence on postoperative MRIs. Differential diagnosis of EC based on radiological data is quite difficult. As aggresive behaviour of this condition has been described following incomplete resections, the treatment of choice is a radical removal of the cyst in one or two stages depending on patient clinical condition.

    A cross-sectional study was conducted from November 2010 to May 2011 to estimate the prevalence of camel hydatidosis, associated risk factors and financial loss in Jijiga municipal abattoir, Somali Regional State, Eastern Ethiopia. Accordingly, of the total 400 inspected camel, 92 (23 %) camels and 109 organs were positive for hydatid cyst with the highest proportion recorded in lung (56 %) followed by liver (33.9 %), spleen (7.3 %) and kidneys (2.8 %). The prevalence of hydatidosis significantly varied among age categories (P < 0.05), sex (P < 0.05) and body condition score (P < 0.05) of camels. Hence, there is higher likelihood for occurrence of camel hydatidosis among the older age groups (OR 1.8, 95 % CI 1.2, 3.3), in female camels (OR 2.8, 95 % CI 1.7, 4.7) and in poor body conditioned camels (OR 4.1, 95 % CI 2.2, 7.9) than younger camels, males and camels with good body condition score, respectively. Of the total 288 examined cysts for fertility and viability, 59.7 % (172/288) were fertile while the rest 24.0 % (69/288) cysts were sterile. Of the 172 fertile cysts 69.8 % (n = 120) were viable and 30.2 % (n = 52) were non-viable. The rest 16.3 % (47/288) cysts were found dead. It was also observed that the pulmonary and hepatic cysts had fertility rate of 63.7 % (116/182) and 57.4 % (54/94), respectively. The total annual direct financial loss recorded in this study as result of organs condemnation due to hydatid cyst, was 12,147.75 Ethiopian birrs ($714.57 or $7.77/camel). If this value could be extrapolated to the infected camel population of the region, financial loss due to hydatidosis could be enormous. In conclusion, this study showed the importance of hydatidosis and the associated direct financial loss due to the condemnation of organs affected by hydatid cyst in the study area.

    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.

    A 56-year-old man presented himself for an intracranial glioblastoma multiforme excision. After being routinely monitored, he was preoxygenated. We induced anesthesia and paralysis with 200 mg propofol, 50 μg fentanyl and 9 mg vecuronium. Direct laryngoscopy with a Macintosh 3 blade revealed a 2x2 cm cyst, pedunculated, arising from the right side of the vallecula preventing the endotracheal intubation. While the patient remained anesthetized, we urgently consulted an otolaryngologist and aspirated the cyst with a 22-gauge needle and syringe under direct laryngoscopy. We aspirated 10 cc of liquid content. This was followed by an uneventful tracheal intubation with a 9.0 enforced spiral cuffed tube. An alternative to fiberoptic intubation may be careful cyst aspiration to facilitate the intubation.

    Hydatid cyst disease may develop in any organ of the body, most frequently in the liver and lung, but occasionally can affect other organs such as the thyroid gland. Although the prevalence of thyroidal cyst disease varies by region, literature data suggest that it ranges between 0% and 3.4%. The aim of this report was to share 2 cases with thyroid hydatid cyst. Two female patients aged 26 and 57 years were admitted to our outpatient clinic with different complaints. While the first case presented with front of the neck swelling and pain, the second case presented with hoarseness, sore throat, and neck swelling. Both patients were living in a rural area in the southeastern region of Turkey and had had a long history of animal contact. Both patients had undergone previous surgeries for hydatid cyst disease. Both patients presented with a clinical picture consistent with typical multinodular goiter, and both underwent total thyroidectomy after detailed examinations and tests. The exact diagnosis was made after histopathologic examination in both patients. They both had a negative indirect hemagglutination test studied from blood samples. They both have had no recurrences during a 4-year follow-up. In conclusion, although thyroid gland is rarely affected, hydatid cyst disease should not be overlooked in differential diagnosis of cystic lesions of thyroid gland in patients who live in regions where hydatid cyst disease is endemic and who had hydatid cysts in other regions of their body.

    Cysts of the bile duct or choledochal cysts are rare diseases in our area. The aetiology is unknown, with the most accepted hypothesis being a pancreatobiliary maljunction anomaly. To analyse the clinical data, diagnosis and treatment of a number of patients with choledochal cyst, as well as presenting an update on this condition. A retrospective descriptive study was performed on paediatric patients diagnosed with choledochal cyst in the last 20 years in a tertiary hospital. A total of 4 choledochal cyst cases in childhood, predominantly female, are pre- sented. The most frequent reason for consultation was vomiting, and presenting with jaundice and choluria in all cases. Patients with choledochal cyst were classified as type I in 3 cases, and one case of type IVa. In all cases surgical treatment was performed; any patient had complications to date. Cysts of the bile ducts have a low prevalence. The treatment of choice is surgical, requiring close monitoring due to the risk of cholangiocarcinoma. Copyright © 2015 Sociedad Chilena de Pediatría.

    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.

  7. New insights about suprapatellar cyst

    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.

    The authors have experienced 11 cases of radiologically or surgically proven choledochal cyst during the period of 4 years, and reviewed radiological and clinical features. The results are as follows: 1. The sex ratio of female to male was 2.7:1. Four were children under 10, and seven were adults over 30 years of age. 2. The most frequent symptom was abdominal pain (45%), which was followed by jaundice (36%) and palpable abdominal mass (27%). 3. Morphologically, 4 cases were type A of Kimura classification (segmental cystic dilatation involving common bile duct; pure type A of Alonso-Lej). The other 7 patients showed some dilatation in the intrahepatic bile ducts as well; i.e. type A' of Kimura classification. 4. The union between the common bile and main pancreatic ducts was at a high position in 5 of 6 patients in whom both ducts were adequately opacified with ERCP, PTC and/or operative cholangiography, forming an abnormally long common channel. 5. Associated choledocholithiasis was reported with increasing frequency. We experienced 4 cases (36.3%) which had multiple stones in the choledochal cyst. 6. Adenocarcinoma were combined in 2 patients; both were females of 38 and 45 years of age. 7. Ten cases were correctly diagnosed preoperatively with ultrasonography. Specific ultrasound diagnosis of a choledochal cyst could be made by identifying two bile ducts entering into the large cyst which was separated from the gallbladder and extended deep onto the portal hepatic. Dilatation of intrahepatic ducts could be easily identified.

    Full Text Available A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

    Intraspinal bronchogenic cysts are rare congenital cystic lesions. In all the reported cases, the cysts have been located in the cervical, upper thoracic or thoracolumbar segments. We report the case of an intraspinal bronchogenic cyst in the sacral location. We present the case of a 5-month-old female with a skin dimple in the midline over the sacral vertebra. Magnetic resonance image of the lumbar and sacral vertebra revealed a dermal sinus tract and an epidural cystic mass at the S2 level. The patient underwent the removal of the dermal sinus tract and the cyst. The cystic mass was shown to be connected to the subarachnoid space through a slender pedicle from the dura. The cyst was diagnosed to be a bronchogenic cyst based on the results of the histopathological examination. We conclude that intraspinal bronchogenic cysts may appear in the sacral location.

    Full Text Available Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts. Unlike a mucocele, which is surrounded by granulation tissue, the salivary duct cyst is lined by epithelium. Salivary duct cysts are more common in the oral minor salivary glands and rarely occur in the major salivary glands, show a marked predilection for the superficial lobe of the parotid, and represent 10% of all salivary gland cysts. Neoplastic differentiation of the lining of the salivary duct cyst has been reported. We report a case of a salivary duct cyst of the left parotid gland, with a review of radiographic and histopathologic features.

    2007-01-01

    Full Text Available Dentigerous cysts are the most common bony lesions of the jaws in children. It is one of the most prevalent types of odontogenic cysts associated with an erupted or developing tooth, particularly the mandibular third molars; the other teeth that are commonly affected are, in order of frequency, the maxillary canines, the maxillary third molars and, rarely, the central incisor. Radiographically, the cyst appears as ovoid well-demarcated unilocular radiolucency with a sclerotic border. The present case report describes the surgical enucleation of a dentigerous cyst involving the permanent maxillary right central incisor; the surgery was followed by oral rehabilitation. Careful evaluation of the history and the clinical and radiographical findings help clinicians to correctly diagnose the condition, identify the etiological factors, and administer the appropriate treatment.

    To determine the prevalence and geographical distribution of hydatidosis and investigate factors that might be expected to influence the prevalence of hydatids in cattle in Queensland north of the Tropic of Capricorn. To determine the effect of natural levels of infection on carcase weight and subsequent economic loss. An abattoir survey conducted in 1981 provided information on the distribution, prevalence and viability of hydatid cysts in cattle from all shires north of the Tropic of Capricorn in Queensland. Livers, lungs and spleens from 10,382 cattle were palpated at abattoirs in Cairns, Townsville and Rockhampton to detect hydatid cysts. Prevalence of infection in cattle in each shire was estimated from results of the abattoir study together with reports of infection in a further 22,185 cattle obtained from abattoir records. Linear modelling was used to define the effect of geographical origin, age, breed and sex on prevalence of infection. Differences in the weights of carcases between infected and non-infected cattle of the same age, sex, breed and property of origin were examined. The economic loss to the beef industry in the region surveyed was estimated. Cattle infected with hydatids originated almost entirely from regions to the east of the Great Dividing Range. The mean prevalence inside this zone was 28% compared with 3% in other areas. Viable protoscoleces were found in 0.7% of cysts. Geographical origin and age of the cattle were the most significant factors influencing prevalence. Infection with hydatids had no effect on carcase weight. Economic loss was limited to that associated with condemnations of organs at meat inspection, estimated to be 0.5 million dollars per annum in 1981 and 6 million dollars in 2004. The distribution of hydatids in Queensland north of the Tropic of Capricorn corresponded most closely with the distribution of small wallabies such as Macropus dorsalis (black-striped wallaby), M parryi (whiptail wallaby) and M rufogriseus

    Sclerotherapy for renal cysts was performed, using 50% acetic acid as new sclerosing agent. We report the methods and results of this procedure. Fifteen patients underwent sclerotherapy for renal cyst, using 50% acetic acid. Because four patients were lost to follow-up, only 11 of the 15 were included in this study. The renal cysts, including one infected case, were diagnosed by ultrasonograpy (n=3D10) ormagnetic resonance imaging (n=3D1). The patient group consisted of four men and seven women(mean age, 59 years; range, 23-77). At first, the cyst was completely aspirated, and 25 volume% of aspirated volume was replaced with 50% sterile acetic acid through the drainage catheter. During the follwing 20 minutes, the patient changed position, and the acetic acid was then removed from the cyst. Finally, the drainage catheter was removed, after cleaning the cyst with saline. After treatment of infection by antibiotics and catheter drainage for 7 days, sclerotherapy in the infected case followed the same procedure. In order to observe changes in the size of renal cysts and recurrence, all patients were followed up by ultrasound between 2 and 8 months. We defined response to therapy as follows:complete regression as under 5 volume%, partial regression as 5-50 volume% and no response as more than 50 volume% of initial cyst volume. No clinically significant complication occured during the procedures or follow-up periods. All cysts regressed completely during follow-up of 8 months. Complete regression occurred as follows: two cysts at 2 months, seven cysts at 4 months, two cysts at 6 months. Two cysts showed residues at the last follow-up, at 4 and 6 months, respectively. The volume of residual cysts decreased to under 5 volume% of initial volume, however. Completely regressed cysts did not recurr during follow-up. Acetic acid sclerotherapy for renal cysts showed good results, regardless of the dilution of sclerosing agent with residual cyst fluid, and no significant

    A cross-sectional study was conducted from December 2008 to March 2009 to assess the status of cystic hydatidosis in cattle slaughtered at Hawassa Municipal abattoir. Out of the total 632 cattle examined visually and manually (palpation and incision), 333 (52.69%) were found harboring hydatid cysts. A significantly higher infection was detected in older cattle (P 0.05, chi(2) = 2.148) was observed as the prevalence was 54.55% for lean cattle followed by medium (53.83%) and fat (46.88%). Of the total 333 infected, 123 (36.9%) had hydatid cysts only in the lung, 23 (6.9%) in the liver, 12 (3.6%) in the spleen, five (1.5%) in the heart, and three (0.9%) in the kidney while the rest 167 (50.2%) had multiple organ infections. Of the 530 viscera harboring hydatid cysts, the highest (52.83%) was lung followed by liver (34.15%), spleen (9.06%), heart (3.39%), and kidney (0.56%). Size assessment made on 874 cysts indicated that 308 (35.3%) were small, 251 (28.7%) medium, 89 (10.2%) large, and 226 (25.9%) were calcified. The distribution of characterized cysts in different organs based on their size was found to be statistically significant (P fertile, 47.3% sterile, and 25.9% calcified or purulent cysts. There was a significant difference in fertility of cyst from different organs (P fertile. Likewise, out of the 121 fertile cysts subjected for viability test, 68 (56.2%) were viable. Considering the current result, the total annual economic loss from organ condemnation and carcass weight loss due to bovine hydatidosis at Hawassa Municipal abattoir was estimated at 1,791,625.89 Ethiopian Birr (ETB; 1USD = 12.93ETB). Results in the study were discussed in light of the situation in different parts of Ethiopia and abroad, and finally, relevant recommendations were forwarded.

    Cystic lesions derived from the synovial and ligamentous structures of the spine have varied histologic appearances. Not uncommonly, there is discrepancy between the clinico-radiologic diagnosis and histology. Therefore, we sought to characterize the histologic features of tissue submitted as "synovial cysts" of the spine. Resected specimens of the spine labeled "synovial cysts" and "lumbar cysts" were histologically evaluated and classified based on histopathologic features. 75 histologic samples of spinal cysts were identified. 31 were classified as synovial cysts (definite synovial lining), 28 showed pseudocystic degeneration of the ligamentum flavum, 7 showed pseudocyst formation without evidence of synovial lining or degeneration of the ligamentum flavum, 8 showed cyst contents only or no histologic evidence of cyst wall for evaluation. Twenty-five cases (33%), especially those showing pseudocystic degeneration of the ligamentum flavum were associated with very characteristic tumor calcinosis-like calcium deposition with surrounding foreign-body giant cell reaction. Histology of "synovial cysts" of the spine shows varied types of cysts; a large proportion are not synovial lined cysts but rather show pseudocystic degenerative changes of the ligamentum flavum often associated with very characteristic finely granular calcifications and foreign body giant cell reaction. This may have implications, not only in understanding the pathogenesis of these lesions, but also in their varied response to non-surgical interventions. This article is protected by copyright.

    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.

    Ectopy is the most common embryogenetic defect of the thyroid gland, representing between 48 and 61% of all thyroid dysgeneses. Persistence of thyroid tissue in the context of a thyroglossal duct remnant and lingual thyroid tissue are the most common defects. Although most cases of ectopic thyroid are asymptomatic, any disease affecting the thyroid may potentially involve the ectopic tissue, including malignancies. The prevalence of differentiated thyroid carcinoma in lingual thyroid and thyroglossal duct cyst is around 1% of patients affected with the above thyroid ectopies. We here review the current literature concerning primary thyroid carcinomas originating from thyroid tissue on thyroglossal duct cysts and lingual thyroid. Copyright © 2016 SEEN.

    Apical periodontitis can appear clinically as apical granulomas or radicular cysts. There is evidence that immunologic factors are involved in the pathogenesis of both pathologies. In contrast to radicular cysts, the dentigerous cysts have a developmental origin. Macrophage polarization (M1 vs M2) is a main regulator of tissue homeostasis and differentiation. There are no studies comparing macrophage polarization in apical granulomas, radicular cysts, and dentigerous cysts. Forty-one apical granulomas, 23 radicular cysts, and 23 dentigerous cysts were analyzed in this study. A tissue microarray (TMA) of the 87 consecutive specimens was created, and CD68-, CD11c-, CD163-, and MRC1-positive macrophages were detected by immunohistochemical methods. TMAs were digitized, and the expression of macrophage markers was quantitatively assessed. Radicular cysts are characterized by M1 polarization of macrophages while apical granulomas show a significantly higher degree of M2 polarization. Dentigerous cysts have a significantly lower M1 polarization than both analyzed periapical lesions (apical granulomas and radicular cysts) and accordingly, a significantly higher M2 polarization than radicular cysts. Macrophage cell density in dentigerous cysts is significantly lower than in the periapical lesions. The development of apical periodontitis towards apical granulomas or radicular cysts might be directed by macrophage polarization. Radicular cyst formation is associated with an increased M1 polarization of infiltrating macrophages. In contrast to radicular cysts, dentigerous cysts are characterized by a low macrophage infiltration and a high degree of M2 polarization, possibly reflecting their developmental rather than inflammatory origin. As M1 polarization of macrophages is triggered by bacterial antigens, these results underline the need for sufficient bacterial clearance during endodontic treatment to prevent a possible M1 macrophage-derived stimulus for radicular cyst

    To determine whether batch solar disinfection (SODIS) can be used to inactivate oocysts of Cryptosporidium parvum and cysts of Giardia muris in experimentally contaminated water. Suspensions of oocysts and cysts were exposed to simulated global solar irradiation of 830 W m(-2) for different exposure times at a constant temperature of 40 degrees C. Infectivity tests were carried out using CD-1 suckling mice in the Cryptosporidium experiments and newly weaned CD-1 mice in the Giardia experiments. Exposure times of > or =10 h (total optical dose c. 30 kJ) rendered C. parvum oocysts noninfective. Giardia muris cysts were rendered completely noninfective within 4 h (total optical dose >12 kJ). Scanning electron microscopy and viability (4',6-diamidino-2-phenylindole/propidium iodide fluorogenic dyes and excystation) studies on oocysts of C. parvum suggest that inactivation is caused by damage to the oocyst wall. Results show that cysts of G. muris and oocysts of C. parvum are rendered completely noninfective after batch SODIS exposures of 4 and 10 h (respectively) and is also likely to be effective against waterborne cysts of Giardia lamblia. These results demonstrate that SODIS is an appropriate household water treatment technology for use as an emergency intervention in aftermath of natural or man-made disasters against not only bacterial but also protozoan pathogens.

    To determine the efficacy of solar disinfection (SODIS) in disinfecting water contaminated with poliovirus and Acanthamoeba polyphaga cysts. Organisms were subjected to a simulated global solar irradiance of 850 Wm(-2) in water temperatures between 25 and 55 degrees C. SODIS at 25 degrees C totally inactivated poliovirus after 6-h exposure (reduction of 4.4 log units). No SODIS-induced reduction in A. polyphaga cyst viability was observed for sample temperatures below 45 degrees C. Total cyst inactivation was only observed after 6-h SODIS exposure at 50 degrees C (3.6 log unit reduction) and after 4 h at 55 degrees C (3.3 log unit reduction). SODIS is an effective means of disinfecting water contaminated with poliovirus and A. polyphaga cysts, provided water temperatures of 50-55 degrees C are attained in the latter case. This research presents the first SODIS inactivation curve for poliovirus and provides further evidence that batch SODIS provides effective protection against waterborne protozoan cysts.

    Full Text Available Primary hydatid disease of spine is rare and spinal hydatitosis constitute only 1% of all hydatitosis. We report a case of recurrent primary intraspinal extradural hydatid cyst of the thoracic region causing progressive paraparesis. The patient was operated 16 years ago for primary spinal hydatid disease involvement and was instrumented dorsally for stabilization.

    A soft tissue aneurysmal bone cyst located in the right gluteus medius of a 21-year-old man is reported. On conventional radiography, the lesion demonstrated a spherically trabeculated mass with a calcific rim. On CT scan, it showed a well-organized peripheral calcification resembling a myositis ossificans. On MRI, it presented as a multilocular, cystic lesion with fluid-fluid levels. The lesion had no solid components except for intralesional septa. Although findings on imaging and histology were identical to those described in classical aneurysmal bone cyst, diagnosis was delayed because of lack of knowledge of this entity and its resemblance to the more familiar post-traumatic heterotopic ossification (myositis ossificans).

    The authors have experienced 11 cases of radiologically or surgically proven choledochal cyst during the period of 4 years, and reviewed radiological and clinical features. The results are as follows: 1. The sex ratio of female to male was 2.7:1. Four were children under 10, and seven were adults over 30 years of age. 2. The most frequent symptom was abdominal pain (45%), which was followed by jaundice (36%) and palpable abdominal mass (27%). 3. Morphologically, 4 cases were type A of Kimura classification (segmental cystic dilatation involving common bile duct; pure type A of Alonso-Lej). The other 7 patients showed some dilatation in the intrahepatic bile ducts as well; i.e. type A' of Kimura classification. 4. The union between the common bile and main pancreatic ducts was at a high position in 5 of 6 patients in whom both ducts were adequately opacified with ERCP, PTC and/or operative cholangiography, forming an abnormally long common channel. 5. Associated choledocholithiasis was reported with increasing frequency. We experienced 4 cases (36.3%) which had multiple stones in the choledochal cyst. 6. Adenocarcinoma were combined in 2 patients; both were females of 38 and 45 years of age. 7. Ten cases were correctly diagnosed preoperatively with ultrasonography. Specific ultrasound diagnosis of a choledochal cyst could be made by identifying two bile ducts entering into the large cyst which was separated from the gallbladder and extended deep onto the portal hepatic. Dilatation of intrahepatic ducts could be easily identified.

    The incidence of epidermoid tumors is between 1% and 2% of all intracranial tumors. The usual locations of epidermoid tumor are the parasellar region and cerebellopontine angle, and it is less commonly located in sylvian fissure, suprasellar region, cerebral and cerebellar hemispheres, and lateral and fourth ventricles. Epidermoid cysts located in the posterior fossa usually arise in the lateral subarachnoid cisterns, and those located in the brain stem are rare. These epidermoids contain cheesy and flaky white soft putty like contents. Epidermoid cysts are very slow growing tumors having a similar growth pattern of the epidermal cells of the skin and develop from remnants of epidermal elements during closure of the neural groove and disjunction of the surface ectoderm with neural ectoderm between the third and fifth weeks of embryonic life. We are presenting an interesting case of intrinsic brainstem epidermoid cyst containing milky white liquefied material with flakes in a 5-year-old girl. Diffusion-weighted imaging is definitive for the diagnosis. Ideal treatment of choice is removal of cystic components with complete resection of capsule. Although radical resection will prevent recurrence, in view of very thin firmly adherent capsule to brainstem, it is not always possible to do complete resection of capsule without any neurological deficits.

    On the basis of the studies listed in the bibliography, this dissertation reports on the pathology, clinical symptoms and radiology of cysts of the semilunar cartilage. The author analyses 118 cases of his own, with special regard to the results of pneumo-arthrographic investigations carried through according to a special technique by Schaefer. In the course of this work, measurements of the meniscal base are for the first time used as radiological criteria indicating the presence of a cyst of the semilunar cartilage. Furthermore the well-known radiological signs of cysts, such as bone defects according to Albert and Keller, light central spot in the meniscal body, as well as Rauber's sign and horizontal rupture, are investigated as to the frequency of their incidence. For that purpose all the X-ray pictures were subjected to a further dose scrutiny. A list of all the 118 cases with their clinical and radiological data is found in the annex, together with the results of the operations and patho-anatomical investigations. (orig.) [de

    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.

    CT is indispensable in the evaluation of renal masses, providing noninvasive and clear transverse images. With wider clinical application of CT, renal cysts have been found more frequently. CT examinations on 500 patients, who underwent CT for the diagnosis of renal diseases except for renal cysts, have been reviewed and analysed. The incidence of renal cysts was 9.6 % without prediction for sexes, but the incidence and sizes of the cysts increased with the advancing age. The upper portion of the kidneys was more frequently involved, but there was no relationship between number, sex and age of the patients. Since renal cysts produce mass effect in the kidneys, understanding of the nature and incidence of the renal cysts is important in diagnosing renal mass lesions. (author)

    Splenic cysts are rare diseases that are diagnosed incidentally during imaging studies. When cysts are recognized, surgical treatment is recommended adapted to the particular case, depending on the size and location of the cyst and the age of the patient in order to avoid dangerous complications such as spleen rupture or cyst infection with abscess. We report 2patients with symptomatic splenic epidermoid cyst treated by laparoscopic cleavage. Laparoscopic cleavage is a surgical option for splenic cyst, with the goal of reducing postoperative complications while preserving splenic function.

    The presence of cysts in the white matter of the central nervous system of patients with tuberous sclerosis (TS) is an uncommon finding that has been reported only recently in neuroimaging studies. This article assesses the prevalence of these lesions in a large series of patients studied by magnetic resonance imaging (MRI) and their relationship to other epidemiological and imaging findings. MRI studies were performed in 46 patients (23 males and 23 females) with a mean age of 12.7 years, and the results were examined retrospectively in the search for cortical tubers, subependymal nodules and white matter nodules, lines and cysts. Nine patients (19.6%) presented cysts in white matter. Seven had only one cyst and the remaining two patients each had two. Multiple regression analysis relating the presence of the cysts with other neuroimaging findings in these patients revealed a statistically significant relationship only with white matter nodules (odds ratio: 7.5; p=0.006). White matter cysts are small, supratentorial lesions of deep location. There is a statistically relationship between the presence of these cysts and that of nodular lesions in the white matter. This finding supports the theory that the cyst originate from white matter nodules. (Author) 17 refs.

    The jaws are host to a variety of cysts due in large part to the tissues involved in tooth formation. Odontogenic cysts (OCs) are unique in that they affect only the oral and maxillofacial region. There are few studies from sub-Saharan Africa. This study was aimed at describing the pattern of various types of cysts in the oral and maxillofacial region in a Kenyan population. This was done at the Departments of Oral and Maxillofacial Surgery and Oral Medicine and Pathology, University of Nairobi Dental Hospital. This was a retrospective audit. All histopathologic records were retrieved from 1991 to 2010 (19 years) and were counted. The following information was extracted and recorded in a data sheet: age, sex, and the type of cystic lesions. There were 194 cysts (4.56%) diagnosed of 4257 oral and maxillofacial lesions. Of these, 64.4% were from male and 35.6% were from female patients with an age range of 1 to 70 years (mean, 23.76 [SD, 14.05] years; peak and median of 20 years). The most common OCs (57.2%) were dentigerous and radicular, whereas the most common nonodontogenic cyst (42.8%) was nasopalatine duct cyst. Other soft tissue cysts reported were epidermoid, branchial, thyroglossal, dermoid, and cystic hygroma. Oral and maxillofacial cysts are not uncommon in this population, the majority being the OC, dentigerous cyst, followed by the nonodontogenic cyst, nasopalatine cyst. The cysts are male predominant and occur 10 to 15 years earlier compared with those in the white population.

    Popliteal (Baker) cysts, meniscal cysts, proximal tibiofibular joint cysts, and cruciate ligament ganglion cysts are cystic masses commonly found about the knee. Popliteal cysts form when a bursa swells with synovial fluid, with or without a clear inciting etiology. Presentation ranges from asymptomatic to painful, limited knee motion. Management varies based on symptomatology and etiology. Meniscal cysts form within or adjacent to the menisci. These collections of synovial fluid are thought to develop from translocation of synovial cells or extravasation of synovial fluid into the meniscus through a tear. Joint-line pain and swelling are common symptoms. Management entails partial meniscectomy with cyst decompression or excision. Proximal tibiofibular joint cysts are rare, and their etiology remains unclear. Pain and swelling secondary to local tissue invasion is common, and management consists of surgical excision. Cruciate ligament ganglion cysts have no clear etiology but are associated with mucoid degeneration of the anterior and posterior cruciate ligaments, knee trauma, and synovial translocation into these ligaments. Knee pain and limited range of motion, especially with exercise, are common presenting symptoms. In symptomatic cases, arthroscopic excision is commonly performed.

    Full Text Available Epidermoid cyst is a common benign cutaneous swelling frequently encountered in surgical practice. It usually presents as a painless lump frequently occurring in hairbearing areas of the body particularly the scalp, scrotum, neck, shoulder and back. Giant epidermoid cysts commonly occur in hairy areas such as the scalp. We present here the case of a rare occurrence of a giant epidermoid cyst in the less hairy area of the right upper thigh mimicking a soft tissue sarcoma. Steps are highlighted for the management of this unusual cyst.

    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 The present study was conducted with an objective to extract all possible interrelated etiological factors of cystic ovary and to evaluate the best treatment protocol in dairy cattle under field condition of temperate region. A total of 54 cattle (47 cows and 7 heifers, suffering from ovarian cyst were retrospectively used to study prevalence and outcome of the disease over a period of 5 years. Highest prevalence was recorded in crossbred Jersey, in 2nd lactation and during summer. Major clinical signs showed by the animals with ovarian cysts (OC were either repeat breeding or anestrus. In case of repeat breeding, irregular cycle (sometimes short and sometimes long in the same cow in 23.33% (7/30, nymphomania in 13.33% (4/30, short cycle (10-15 days in 23.33% (7/30 and long cycle (23-30 days in 10% (3/30 cases were noticed. In remaining 30% cases (9/30 normal cycles were noticed. Right ovary affected more than left one and mean number of cysts recorded were 1.17 per animal. Follicular cysts could be treated with GnRH in 75% (9/12 cases, and, luteal cysts with cloprostenol in 83.33% (10/12 cases. However, in cases where cyst could not be differentiated by rectal palpation, administration of cloprostenol 9 days after HCG treatment was found 66.67% (8/12 effective in curing the disease. It is concluded that both follicular and luteal cysts can be treated successfully with GnRH/hCG and prostaglandin or its analogue, respectively.

    Full Text Available Up to now, no complete study was carried out about the prevalence and location of periapical granuloma and radicular cysts from the point of view of clinical symptoms (e.g. pain and swelling fistula in Iran. The data was collected from the files available in the Department of Pathology, faculty of Dentistry, Tehran University of Medical Sciences. With a consideration on different therapeutic methods. a proper method was selected. Radicular cyst occurred in 59.3 percent of 324 cases while 45.7 percent were granuloma. The most common incidence of these lesions was in the range of 24-25 years old. The most common location of lesions was the maxillary anterior. Sinus tracts occurred in 74 of all cases. 47.3 percent of these patients have been previously received root canal therapy. It is noticeable that 24 percent of all patients were treated endodontically before surgery. Higher incidence of granuloma occurred in small lesions while cysts were more common in large lesions. 232 of all cases showed one of the clinical symptoms, 16% pain, 35.8% swelling and 22.8% fistula. No symptoms were found in 92 cases.

    García Escudero, D; Torres Roca, M; Hernández Contreras, M E; Sánchez Rodríguez, C; Oñate Celdrán, J

    Hypertension is a prevalent disease in developed countries. Adrenal masses, and especially adrenal cysts, are a rare and usually asymptomatic finding, which can go unnoticed or be detected as incidental findings in imaging tests. These circumstances make the multidisciplinary approach mandatory. The case is presented on a 72 year-old woman with uncontrolled high blood pressure referred to the Urology Department due to the incidental finding of a right retroperitoneal mass. A functional and imaging study was performed, establishing a diagnosis of adrenal cyst causing hypertensive symptoms. A literature search was performed in order to assess diagnostic and therapeutic approaches. With the diagnosis of adrenal cyst causing uncontrolled high blood pressure, a right laparoscopic adrenalectomy was performed. After surgery the patient has maintained blood pressure within the normal range. A multidisciplinary approach is necessary for the management of rare diseases. The surgical approach, if possible, should be laparoscopic. Copyright © 2017 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.

  10. Nonsurgical root canal therapy of large cyst-like inflammatory periapical lesions and inflammatory apical cysts.

    2009-05-01

    It is a general belief that large cyst-like periapical lesions and apical true cysts caused by root canal infection are less likely to heal after nonsurgical root canal therapy. Nevertheless, there is no direct evidence to support this assumption. A large cyst-like periapical lesion or an apical true cyst is formed within an area of apical periodontitis and cannot form by itself. Therefore, both large cyst-like periapical lesions and apical true cysts are of inflammatory and not of neoplastic origin. Apical periodontitis lesions, regardless of whether they are granulomas, abscesses, or cysts, fail to heal after nonsurgical root canal therapy for the same reason, intraradicular and/or extraradicular infection. If the microbial etiology of large cyst-like periapical lesions and inflammatory apical true cysts in the root canal is removed by nonsurgical root canal therapy, the lesions might regress by the mechanism of apoptosis in a manner similar to the resolution of inflammatory apical pocket cysts. To achieve satisfactory periapical wound healing, surgical removal of an apical true cyst must include elimination of root canal infection.

    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. 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 . 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. 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.

    Full Text Available An epidermoid cyst is a benign cyst that can occur in any part of the body. The most common age group for this cyst is 20–40 years. It's extremely rare in oral cavity accounting for only 1.6%. The cyst develops from the ectodermal tissue. It represents the most common cutaneous cysts. A 6 years old female patient presented with a complaint of swelling in the floor of the mouth. It measured 4 × 5 cm in size. Surgical excision with primary closure was performed. We present this case because of its rare location, mistaken for other entities, like a ranula and its occurrence at an early age. After excision, an oval-shaped mass of 4 × 5 cm has been described in this case. The histopathological report confirms the diagnosis of epidermoid cyst. The epidermoid cyst commonly occurs in middle-aged adult group, especially over the face, scalp & trunk area. Surgical excision is the treatment of choice in such case. Epidermoid cyst of the oral cavity is an uncommon entity. Although it's common in middle-aged adult but sometimes it may occur in pediatrics age group.

  1. Giant Presternal Dermoid Cyst: An Adult Case

    African Journals Online (AJOL)

    Dermoid cysts are benign lesions located in the subcutaneous tissue containing epidermis and epidermal appendages. They are commonly found in the head and neck region (1,2). The differential diagnosis includes other subcutaneous cystic lesions such as sebaceous cyst and in the African context, tuberculous abscess.

  2. Orbital dermoid and epidermoid cysts: Case study

    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.

    Full Text Available INTRODUCTION: Hydatid disease has a worldwide distribution and causes health problems in endemic countries. The parasite has a "dog - sheep" cycle with man as an intermediate accidental host. When humans ingest the eggs of the tapeworm, the embryos that emer ge penetrate the intestinal mucosa and are transported via the circulation to various organs. Most commonly they reach the liver, lungs and the other organs are rarely affected. Primary hydatid cyst of skeletal muscle is rare, occurring in 1 - 3% of all case s. (1,2 The prevalence of intramuscular hydatid disease is reported to be less than 0.5% , because muscle is an unfavourable site for infestation because of high levels of lactic acid in muscle. (3 The diagnosis is difficult because of the unusual location, low prevalence and complicated cysts may mimic solid or complex lesions. (4 The differential diagnosis in these cases must include malignant soft - tissue tumors such as myxoid liposarcoma, soft tissue abscesses and chronic hematoma. (5 Hydatid disease of h umans caused by Echinococcus granulosus has been recognized as a major public health problem. It is found in all sheep - raising countries of the world. In India, the highest prevalence is reported from Andhra Pradesh and Tamil Nadu. (6 Injudicious approach in the management of these rare presentations may be the root cause of severe anaphylactic shock and systemic dissemination. We report an unusual case of primary hydatidosis of the paraspinal muscles

    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.

    2013-04-01

    Full Text Available Reports on keratinous cysts involving the tarsal plate are very rare. Herein, we present a 69-year-old male patient with a giant tarsal keratinous cyst of the right upper eyelid who was misdiagnosed as chalazion of the eyelid. Interventional case report with cytopathologic correlation. Due to recurrence after the surgery for presumed chalazion, the patient was referred to our clinic for tumor evaluation. In the second surgery, which was performed in our clinic, the lesion was found to have a fine capsule and was totally excised. Histopathologic examination revealed keratinous cyst of the tarsal plate. Keratinous cyst must be considered in the differential diagnosis of tarsal plate lesions, as the curettage of the keratinous cyst might result in multiple recurrences.

    Full Text Available Background. A six-year-old boy presented with a large progressive intracorneal and scleral cyst. Two years before, bilateral cataract surgery through a 6.5-mm corneal incision was performed elsewhere.Methods. The posterior wall of the cyst could be excised, as well as the anterior wall in the sclera. Upon histo-pathology the cyst wall was lined by epithelium. The epithelial cells of the anterior side in the cornea were removed with a curette and a corpus alienum drill. Three and a half years after removal of the cyst, there was no recurrence. Visual acuity was 0.8. Conclusions. An intracorneal and scleral inclusion cyst was successfully removed by surgical excision and the removal of epithelial cells by a curette and a corpus alienum drill.

    1995-12-01

    The calcifying odontogenic cyst (COC) is a rare lesion that involves the jaws which, at times, may evolve into a solid, benign, tumor-like mass. There is no significant sex predilection, but it is probably more common in later life. The diagnosis is base only on histologic examination that represents, in the best of cases, the only way to differentiate the COC from other pathologies. Such lesions include: odontogenic cyst, residual cyst, globulomaxillary cyst, lateral periodontal cyst, ameloblastoma (multicystic and unicystic), odontogenic mixoma, and still with calcifying odontogenic epithelial tumor (Pindborg tumor) and adenomatoid odontogenic tumor. The authors report a case of COC, starting point for a review of the clinical, radiographic and histomorphologic features of the lesion.

    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.

    The purpose of this study was to evaluate the CT findings of thyroglossal duct cysts. Sixteen patients with pathologically proved thyroglossal duct cysts were included in the study. CT scans were assessed retrospectively for shape, size, location, density of the central portions, septations, rim enhancement, changes in the adjacent fascial planes and investment within the strap muscles in the infrahyoid cysts. Thirteen cases of thyroglossal duct cysts were seen as round or oval cystic masses, two cases of them were seen as irregular-shaped lobulated cystic masses, and one case was seen as ovoid soft tissue mass. The cysts were from 1.4 to 5.7 cm in diameter (mean, 2.6 cm). The cyst was infrahyoid in 15 cases and suprahyoid in one case. The cyst was located in midline in eight cases, off midline in four cases, and both midline and off midline in four cases. The density of the central portions ranged from 15 to 82HU (mean, 32HU). Septations were noted in four cases. Rim enhancement was seen in 14 cases (93%), and heterogeneously enhancing soft tissue mass was seen in one case. In four cases, abnormal fascial planes were observed. All but one of the infrahyoid cysts (14/15) were embedded within the strap muscles, and one case of them was located anteriorly to strap muscles. CT permits one to make the diagnosis a thyroglossal duct cyst with a high degree of accuracy, as it can differentiate thyroglossal duct cysts from the other anterior neck masses by their typical location, characteristic morphology, and investment within the strap muscles.

    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.

    The authors evaluated six cases of surgically proven choledochal cysts diagnosed by real time ultrasonography. The results were as follows: 1. The male to female ratio was 1:5, and the age distribution was 5 cases in adult and one in 5 year old girl. 2. The most frequent symptom was abdominal pain, which was followed by palpable mass and thin jaundice in frequency order. 3. All of them were type A' of Kimura classification, morphologically. 4. Of 5cases, 2 cases showed markedly distended gallbladder. Remaining one case was received cholecystectomy 15 years before this study. 5. Associated choledocholithiasis was reported to be rare, but we found 2 cases of multiple stones and 2 cases of single stone. 6. Combined other lesions were found in 3 cases - - chronic pancreatitis,pancreatic cancer, and ascites by bile leakage. 7. Ultrasonography can easily evaluate intrahepatic bile duct as well as extrahepatic bile duct, so the authors correctly diagnosed choledochal cyst type A' of Kimura classification by ultrasonography alone in 3 cases among 6

    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.

    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.

    To evaluate the characteristic sonographic findings of Baker's cyst and to find out the possible factors which can influence the decision of treatment plan we performed a retrospective analysis of ultrasonograms of 21 proved Baker's cyst in 20 patients. The cysts were ovoid (52%) or elongated (48%) in shape. In 90.5%, there was tail-likelapering end toward the joint space of the knee. In 19%, there was tail-like tapering end toward the joint space of the knee. In 19%, there was fine or coarse eye-catching within the cyst. The coarse internal eye-catching was confirmed as hemorrhage within the cyst. In 62%, the connecting stalk could be traced to the head of gastrocnemiusmuscle. It was sharp in 69.2% and blunt in 30.8%. Fifty percent of cysts with blunt connecting stalk developed post-operative recurrence. In conclusion, ultrasonography of Baker's cyst should be performed with special emphasis on the internal eye-catching for the evaluation of the possible complication and on the connecting stalk for the decision of the surgical approach

    Ganglion cysts of the temporomandibular joint are very rare and always misdiagnosed as synovial cyst, parotid gland tumor, or other cystic lesions. They present with pain, swelling, or dysfunction. Image studies could facilitate to identify the tumor mass from the adjacent soft tissue, but a definitive diagnosis could be made from the pathologic report.A 59-year-old woman presented to the clinics with a chief complaint of a painless swelling mass in the right preauricular region of 3-month duration. Computed tomography was performed, which showed a small radiolucent lesion adjacent to the right condyle. Local excision was performed, and the specimen was sent for histologic examination.Microscopic examination showed a cystic space walled by dense fibrous connective tissue without epithelial or endothelial lining. Immunohistochemical staining of these lining cells showed positivity for vimentin and negativity for cytokeratin. These findings were consistent with the diagnosis of ganglion cyst.Ganglion cysts present as unilobulate or multilobulate cysts that arise from the collagenous tissue and is filled with highly viscous fluid. It does not communicate with the joint cavity. In contrast, synovial cyst is a true cyst lined by cuboidal or flattened cells from the synoviocytes and is filled with gelatinous fluid. It may or may not communicate with the joint cavity. Excision is the treatment of choice of symptomatic cystic lesions. Incomplete excision of these lesions may cause further recurrence or infection. Thus, injection of hydrocortisone or aspiration may be considered as an alternative management.

    The aim of this retrospective study was to investigate uveal cysts in domestic cats by identifying prevalence, predispositions, location, presumed etiologies, and sequelae. The clinical databases of two referral hospitals (The Animal Health Trust in the UK and Animal Eye Care in Australia) were searched to identify cats that had been diagnosed with uveal cysts, either as an incidental finding or as the reason for referral. Thirty-six cases were found. The signalment of the patients was recorded, along with any relevant previous clinical history, treatment, follow-up, and sequela. The data were compared with the unaffected feline populations examined by ophthalmologists in the two hospitals over the same 10-year time period. Thirty-six cats were affected, from a total examined population of 5017 (prevalence 0.72%). Twenty-one of the 36 cats were Burmese. The two centers examined 516 Burmese cats in the same time period, giving an incidence in Burmese cats of 4.1%. The mean age of affected cats at presentation was 10.25 years (SD = 4.12 years), and female cats accounted for 23 of 36 of the cases. Only 2 of 36 cats had concurrent intraocular disease. Uveal cysts in domestic cats are rare ophthalmic findings, and in most cases, they do not cause any clinical problems The Burmese breed is overrepresented in the data, with a relatively high prevalence of uveal cysts. © 2016 American College of Veterinary Ophthalmologists.

  9. Posttransplant epidermoid cysts secondary to small graft hair transplantation.

    1995-10-01

    Epidermoid cysts sometimes result from small-graft hair transplantation. Although hair transplant surgeons are aware of this complication, it has not been reported to date. Our purpose is to report the clinical and histological features of posttransplant epidermoid cysts. Four patients with posttransplant cysts, and the histological features of two of these cysts, were reviewed. All cysts occurred at the site of a recent micro- or minigraft, and were small; one had become infected. Serial sectioning of one scalp biopsy showed a micrograft lying in the subcutaneous tissue in close proximity to an epidermoid cyst. The cyst apparently arose from the follicular infundibulum of the graft. Posttransplant epidermoid cysts are examples of epidermal inclusion cysts. They are treated by conservative excision, and may require drainage for secondary infection. Careful operative technique should prevent some of these cysts.

  10. Ligamentum flavum cyst: An uncommon but recognizable and surgically correctable category of juxtafacet cyst

    Directory of Open Access Journals (Sweden)

    Waseem Mehmood Nizamani

    2018-02-01

    Full Text Available Ligamentum flavum cyst is considered as a category of juxtafacet cyst and is recognized to be rare cause of cord compression and radiculopathy. The pathogenesis of these cysts is not yet fully understood, but it has been proposed that continuous stress to this ligament due to minor repetitive trauma, such as in spondylolisthesis and degenerative disc disease, may lead to the development of cyst. Intraspinal cyst can encroach and displace neural structures that can lead to neurologic symptoms. Although a rare entity, intraspinal cyst should be included in the causative factors of neurogenic claudication or lumbar radiculopathy based on typical magnetic resonance imaging appearance. Timely diagnosis is also imperative in this condition due to a better surgical outcome.

    Full Text Available An unilateral corneal epithelial inclusion cyst in a 7-year-old male Boxer dog is reported. The cyst had been observed for thirty days, was unique, not congenital and only one eye was involved. Seven months prior to the referral the dog had manifested indolent corneal ulcer treated with grade keratotomy and third eyelid flap. The cyst was removed by superficial keratectomy followed by a conjunctival pedicle graft. Recovery was uncomplicated and there wasn?t recurrence seven months after the surgery.

    Full Text Available Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond with hyperintense signal on T1-weighted MRI. We present a case of an adult patient with rupture of an intracranial dermoid cyst, precipitated by minor trauma.

    The calcifying odontogenic cyst is rare lesion having features of both cyst and neoplasm. Clinically it frequently occurs in young adult and more frequent in the anterior area of the jaw. Radiographically, this lesion has several radiopaque foci within unilocular or multilocular radiolucency. The authors experienced cystic and neoplastic types of calcifying odontogenic cysts in the anterior area of the mandible in a 16-year-old male and 21-year-old female patients who suffered from pain, swelling, and teeth displacement on the affected area. And we discussed the clinical , radiological and histopathological features with a brief review of the literatures.

    2012-02-01

    Parathyroid cysts are rare causes of neck swelling accounting for 0.6% of thyroid and parathyroid lesions. They may be functional, resulting in the release of parathyroid hormone, or non-functional. Non-functional cysts may be cosmetically unacceptable or cause dysphagia, dyspnoea or recurrent laryngeal nerve palsy as a result of compression. This article presents a young woman who was diagnosed with a thyroid cyst both on examination and imaging. However, the final histology confirmed this to be parathyroid in origin and this should be considered in the differential of such neck swellings.

    2016-01-01

    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.

    Endodermal cysts are rare congenital intracranial lesions. Although histologically benign, they can become symptomatic as a result of mass effect and cause neurological deficits. We report a 30-year-old woman who presented with paresis of her right oculomotor nerve. Magnetic resonance imaging showed a 13 x 8-mm cystic lesion originating from the right oculomotor nerve at its exit from the mesencephalon. She underwent craniotomy, biopsy, slit resection, and drainage of the cyst. To our knowledge, endodermal cysts have not been previously described in relation to the oculomotor nerve. (orig.)

    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.

    Infertility is a medical and psychosocial problem with a high prevalence. There are different treatments for this problem in Iranian traditional medicine. A 28-year-old woman presented with the complaints of 4 emergency operations of the left ovarian cyst during 4 years and infertility. Diagnostic laparoscopy showed an ovarian cyst, adhesion, and endometriosis. Hysteroscopy was unremarkable. After 2 months of letrozole administration, the ovarian cyst ruptured again. Considering the failure of conventional treatments, Iranian traditional medicine products were administered to the patient. After 3 months, the patient conceived and delivered a healthy boy through normal vaginal delivery. These compounds may help with pregnancy as a uterine tonic, vitalizer, and aphrodisiac with brain and cardiac tonic properties. PMID:27932523

    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.)

    Swelling of upper lip can results from various diseases such as salivary tumors, infections and inflammatory diseases and cyst, typically involving unerrupted teeth, are sometimes associated with supernumerary teeth in the maxillary anterior incisor region called the mesiodens. Mesiodens with dentigerous cyst is actually a rare case in the world and of course in Bangladesh. The overall prevalence of this type of cyst is only 0.15-1.9% of the total population. Recently we have experienced this kind of case like dentigerous cyst with mesiodens in the department of dentistry, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) Hospital. The patient was 24 years old male young complaining of slow growing painless swelling on the upper lip region for the last several years. Clinical examination revealed a soft intra oral swelling in the labial surface of maxillary incisor region and there was also extra orally upper lip swelling. Radiographic examination demonstrated a large radiolucent area with a mesiodens extending to the root of both lateral incisors. The patient was treated surgically by enucleation of total cysts and surgical extraction of mesiodens under local anesthesia.

    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.

    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.

    Full Text Available The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagnosis is primarily made clinically; if necessary, this is complemented by imaging. This paper reports the case of a 39-year-old male patient who complained of pain in the right upper premolar region and poor aesthetics due to a firm tumor in the right wing of the nose. Initially, this was thought to be due to an odontogenic abscess; however, the differential diagnosis was that a nasolabial cyst was communicating with the apex of teeth 14 and 15. Surgical treatment was carried out, followed by histopathological examination and concomitant endodontic treatment of the teeth involved.

    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.

    Full Text Available Bronchogenic cysts are congenital foregut malformations forming from abnormal budding of the bronchial tree between the 4th and 6th weeks of embryonic development. While identified primarily in children, the cysts are often asymptomatic and may not be identified until adulthood. Most (70% are within the middle mediastinum and contain fluid or proteinaceous material. When involving the parenchyma, they generally do not communicate with the tracheobronchial tree. Communication with the airways may develop following infection, procedures, or trauma and may result in lesions with an air-fluid level (Figures 1 and 2. Bronchogenic cysts may be complicated by infection, bleeding, fistula formation, or most concerning, by malignant transformation. Unless the cyst contains air, it may manifest as a solitary pulmonary nodule on plain radiographs. Computed tomography or T2-weighted MRI images are used to confirm the diagnosis.

    Full Text Available Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly.

    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.

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

    Arachnoid cysts are very common lesions in paediatric patients, with treatment depending on their location and symptomatology. They are usually solitary cysts but may be associated with other central nervous system diseases such as tumours and congenital deformities. We describe the case of a neonate diagnosed with an arachnoid cyst of the quadrigeminal cistern treated by endoscopy. After the operation, the child's condition worsened; a CT scan revealed a midline posterior fossa tumour not visible in the preoperative neuroradiological tests. The tumour, a medulloblastoma, was partially removed. Given the child's age and the poor prognosis, oncological treatment was not undertaken. The association between medulloblastoma and arachnoid cyst is very rare, and we could find only one such case in the literature. Copyright © 2012 Sociedad Española de Neurocirugía.

    Full Text Available Epidermal inclusion cysts are uncommon in the breast, but the consequences can besevere when these cysts occur in the breast parenchyma. Here,we report two suchcases. The patient in case 1 was an 37-year-old woman with a 3-cm palpable mass inthe right breast. Mammography revealed a round and smoothly outlined mass, whichindicated a benign tumor, and sonography showed an irregularly shaped and heterogeneoushypoechoic mass, fibroadenoma was suspected on the basis of clinical andimage findings, but excisional biopsy revealed an epidermal inclusion cyst. The patientin case 2 was a 50-year-old woman with a 2.5-cm lesion in the left breast. Mammographyrevealed a round, dense, smoothly outlined mass, and sonography showeda well-defined, central hyperechoic mass. . Breast cancer was suspected on the basisof the sonographic findings and the age of the patient, but the resected specimen revealedan epidermal inclusion cyst. Although epidermal inclusion cysts are benign,occasionally they may play a role in the origin of squamous carcinoma of the breast. .Mammographic and sonographic features of an epidermal cyst may mimic a malignantlesion. Malignant change appears to occur more frequently in epidermal inclusioncysts in the mammary gland, compared to common epidermal inclusion cysts,and this may be associated with origination of mammary epidermal inclusion cystsfrom squamous metaplasia of the mammary duct epithelium.Epidermmoid inclusion cyst of the breast is potentially serious, although such cystsare rare, and differentiation from a malignant or benign breast tumor is required. Excisionis probably the most appropriate treatment, and can eliminate the possible riskof malignant transformation.

    Probiotics are viable by definition, and viability of probiotics is often considered to be a prerequisite for the health benefits. Indeed, the overwhelming majority of clinical studies in the field have been performed with viable probiotics. However, it has also been speculated that some of the mechanisms behind the probiotic health effects may not be dependent on the viability of the cells and, therefore, is also possible that also non-viable probiotics could have some health benefits. The efficacy of non-viable probiotics has been assessed in a limited number of studies, with varying success. While it is clear that viable probiotics are more effective than non-viable probiotics and that, in many cases, viability is indeed a prerequisite for the health benefit, there are also some cases where it appears that non-viable probiotics could also have beneficial effects on human health.

    1991-01-01

    This paper reports on the diagnosis of mediastinal foregut cysts which are difficult to establish even with CT, because these lesions often have high attenuation numbers similar to tumors. This study was undertaken to determine the value of MR imaging in the diagnosis of foregut cysts. MR imaging of 58 mediastinal masses was performed between 1986 and 1991 at 0.5 T, with T1- and T2-weighted images obtained. Seven foregut cysts were identified. Five were pathologically proven; in two cases the diagnosis was based on clinical findings and radiologic stability. Signal characteristics were compared with those of 52 pathologically proven mediastinal masses: six thymomas, 10 thyroid goiters and carcinomas, 11 neurogenic tumors, 15 lymphomas, and 10 miscellaneous masses. Fat and muscle were used as internal standards of signal intensity (SI). All foregut cysts were very bright on T2-weighted images. On T1-weighted sequences, two had low SI, but the remaining five showed high SI. These differences reflected variability in cyst protein content, high SI indicating the presence of mucus. On T1-weighted images, low SI was identified in most other mediastinal masses, but uniform high SI was specific for foregut cysts. Our series did not include any fatty lesions, as these were easily recognized on CT scans

    Spinal meningeal cysts are a rare benign disease that can cause myelopathy. In most cases, spinal meningeal cysts consist of an arachnoid membrane. To the best of our knowledge, few articles have report on intradural spinal meningeal cyst consisting of dura mater. A 58-year-old man presented to our institute with aggravation of clumsy hands and dysesthesia of the feet. Magnetic resonance imaging of the entire spine revealed a cystic lesion compressing the spinal cord posteriorly. Cyst fenestration and placement of the cyst-subarachnoid shunt was performed via an anterior approach. Postoperatively, the histopathologic results revealed that the cyst wall consisted of a dura mater-like membrane. The patient's symptoms resolved without the appearance of any new neurologic deficits. The etiology of spinal meningeal cysts remains unclear. Spinal meningeal cysts consisting of dura mater (spinal dural cysts) are extremely rare. Treatment with only decompression with laminectomy causes enlargement of the dural cyst later.

    Chrysophytes, also known as the golden-brown algae (classes Chrysophyceae and Synurophyceae), often form an essential component of phytoplankton in oligotrophic northern waters. All chrysophytes are believed to produce siliceous resting stages which are often well preserved and abundant in the sediments of most lakes. These resting stages also known as stomatocysts or simply cysts have recently been used in a variety of palaeoenvironmental studies linking cyst assemblages to certain environmental variables such as temperature, pH, salinity and ice cover times. For most of the cysts the cyst producing chrysophyte species is still unknown. Cyst identification is based on the size, shape, ornamentation and the pore morphology of the cyst. The problem however is the minuscule surface structure of the cyst which can often be detected only using a Scanning Electron Microscope (SEM). The use of a SEM is usually expensive and time-consuming but leaves an image of each cyst counted for future reference. The problem with using a SEM is the fact that, unlike with a light microscope, you cannot see through the cyst if the pore is not visible and therefore you are left with a large number of cysts which in some cases have several different identity options. The use of a light microscope is faster but cysts often have to be put into collective categories which can lead into problems in palaeoreconstructions if cysts in the same group have different environmental preferences. More problems in identification arise when cysts are corroded in the sediment or not fully developed. Since no larger scale chrysophyte cyst studies have previously been carried out in Finland (or Fennoscandia), the sediment material also contains many previously undescribed cyst morphotypes. Here we discuss the challenges of cyst identification and the use of chrysophyte cysts in paleoclimatic reconstructions based on circa 15000 SEM images of cysts in Finnish lakes.

    Full Text Available Hydatid cyst is a zoonotic infection usually caused by Echinococcus granulosus. Hydatid cysts are most often localized in the liver and lungs. Isolated cases of hydatid cyst in soft tissue is very rare. The incidance of isolated soft tissue hydatid cyst is 2.3% in endemic areas. Medical treatment is successful in 30-40% of cases. The first choice of treatment is surgery, especially in atypical localization of hydatid cyst. We aimed to present our patient with ankle hydatid cyst, a rare case in the literature.

    Abdennour, S; Allag, S; Benhalima, H

    2014-12-01

    An amygdaloid cyst is a rare high laterocervical cystic tumor arising from the second branchial cleft. It accounts for 2% of laterocervical tumors and up to 85% of second branchial cleft abnormalities [1]. The incidence of intracystic squamous cell carcinoma ranges from 4 to 22% [2]. The diagnosis of primary carcinoma or intracystic metastasis is a controversial issue. We report a rare case of degenerate amygdaloid cyst meeting the diagnostic criteria for intracystic squamous cell carcinoma determined by Martin and Khafif. A 73-year-old female patient consulted for a left cervical swelling in 2010; the diagnosis was an amygdaloid cyst. She had a history of squamous cell carcinoma of the hard palate (T1NoMo) surgery and radiation therapy in 2009, without recurrence. Three years later, the swelling increased to a large size without any cervical node involvement. An exploratory cervicotomy with histological study revealed intracystic squamous cell degeneration. Primary squamous cell carcinoma location in the wall of an amygdaloid cyst is extremely rare and a highly controversial issue. The challenge is to be able to discriminate between a cystic metastasis of squamous cell carcinoma of the aerodigestive tract and a primary squamous cell carcinoma located in the wall of an amygdaloid cyst. Martin and Khafif defined specific criteria to confirm the diagnosis of primary branchiogenic carcinoma. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    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.

  11. Postmenopausal Vaginal Endometriotic Cyst: A Case Report

    Directory of Open Access Journals (Sweden)

    Esengul Turkyilmaz

    2016-07-01

    Full Text Available A seventy-three-year-old patient%u2019s vaginal examination revealed a semi-mobile cystic structure visualised at the middle third portion of the posterior vaginal wall. The cyst was excised and the cyst wall was sent for pathological examination. The histopathological examination of the cyst with CD10 staining and tests for nuclear estrogen receptor positivity and nuclear progesteron receptor positivity revealed that the cyst wall contained endometrial stromal cells, endometrial surface epithelial cells, and hemosiderin-laden macrophages. Endometriosis externa was diagnosed based on the above findings. The case we report here, of an isolated vaginal endometriotic cyst, is unique because of its presentation in a postmenopausal woman without any history of infertility, any gynecologic surgery, or hormone replacement therapy. The reasonable explanation for this case might include certain mechanisms such as the self-sustaining existence of endometriotic cells that were implanted during the premenopausal period to the vagina and that maintain local estrogen production. No single hypothesis can explain the pathophysiology of endometriosis, given all of its various forms and presentations.

  12. Cytogenetics of jaw cysts - a pilot study.

    Manor, Esther; Brennan, Peter A; Bodner, Lipa

    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.

  13. Pathogenesis of odontogenic cysts: an update.

    Science.gov (United States)

    Chindia, M L

    1991-04-01

    This article briefly reviews the origin, classification and pathogenesis of the various odontogenic cysts. Keratocysts and follicular cysts are said to be developmental lesions arising from the remnants of the dental lamina and the cell rests of the dental follicle respectively. The radicular cysts are the most commonly occurring lesions associated with the apices of non-vital teeth. They are said to arise from proliferation of the cell rests of Malassez in chronically inflamed granulomata. It is noted that bone resorption is the major requirement for any bony lesion to expand; hence the interest in the role of diverse cellular and chemical mediators of bone resorption in disease. The current concepts of the role, in cyst initiation and growth, of enzymes including cellular metabolites and cytokines are presented. Evidence on the activities of collagenase, arachidonic acid metabolites, leukotrienes, hydroxyeicosatetraenoic acids, interleukin--1 and prostaglandins is cited. It is observed that the understanding of these cellular and molecular biological behaviour patterns may yield more appropriate information necessary for the development of more effective management modalities for such tissue degrading lesions as odontogenic cysts.

    The viability of bacteria in oligotrofic bogs and fens was determined by the luminescent microscopy method with the help of a two-component fluorescent dye (L7012 LIVE/DEAD). Living bacterial cells were found in the entire peat profiles. Their portion was maximal (up to 60%) in the upper layers and did not exceed 25% in the lower layers. The portion of dead bacterial cells varied from 3 to 19%, and dormant cells constituted 25 to 95% of the total number of bacterial cells. The numbers of dormant cells increased down the profiles irrespectively of the peat type. The portion of nanoforms did not exceed 5% of the total. The cells of the nanoforms, unlike the bacteria of typical sizes, were characterized by their high viability (93-98%).

    The objective of this study was to investigate the value of cyst fluid carcinoembryonic antigen (CEA) in combination with cytology and viscosity for the differential diagnosis of pancreatic cysts. We retrospectively reviewed our data for patients who underwent endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and cyst fluid analysis. We investigated the sensitivity, specificity and accuracy of the combination of cyst fluid CEA, cytology and viscosity testing. A total of 177 patients underwent EUS-FNA and cyst fluid analysis. Of these, 48 subjects were histologically and clinically confirmed to have pancreatic cysts and were therefore included in the analysis. Receiver operator curve analysis demonstrated that the optimal cutoff value of cyst fluid CEA for differentiating mucinous versus nonmucinous cystic lesions was 48.6 ng/mL. The accuracy of cyst fluid CEA (39/48, 81.3%) was greater than the accuracy of cytology (23/45, 51.1%) or the string sign (33/47, 70.2%). Cyst fluid CEA in combination with cytology and string sign assessment exhibited the highest accuracy (45/48, 93.8%). Cyst fluid CEA was the most useful single test for identifying mucinous pancreatic cysts. The addition of cytology and string sign assessment to cyst fluid CEA increased the overall accuracy for the diagnosis of mucinous pancreatic cysts.

    2013-11-01

    Supratentorial endodermal cysts are very rare pathological entities. Their pathoembryology is largely unknown and they can represent a diagnostic challenge. A research performed on the PubMed database in December 2010, to screen for supratentorial endodermal cyst studies, demonstrated that since 1960 only 31 supratentorial endodermal cysts have been described in the literature, including our case: a 42-year-old woman with a parasellar endodermal cyst. These lesions are usually benign. As with other types of brain cysts, the signs and symptoms caused by supratentorial endodermal cysts are mainly linked to the compression or irritation of surrounding neural structures. Upon neuroimaging examination, they typically appear as a round or lobulated mass. The signal intensity may vary depending on the protein content of the cyst. The majority of reported supratentorial endodermal cysts were completely excised with good or excellent results. Incomplete excision can result in an increased risk of recurrence, infection, and dissemination. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available 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.

    Full Text Available Background: Echinococcosis/hydatidosis is considered endemic in Mauritania. The aim of this study is to present an epidemiological study on the echinococcosis in man and animals in the Nouakchott region. Methods: The internal organs from livestock carcasses were inspected for research of hydatid cysts. The hydatid fluid was examined for research of the protoscoleces. Dogs were necropsied for the collect of Echinococcus granulosus.Results: In the Nouakchott Hospital, 24 surgical operation of human hydatid cysts have been per­formed, out of which 50% were localised in the lung, 33% in the liver and 17% elsewhere. Then, the incidence rate would be of 1.2% per 100 000 inhabitants in Mauritania. In the dog, the prevalence rate is 14%. The average number of E. granulosus on the whole dogs is 172 and 1227 on the positive dogs. Concerning the livestock, hydatid cysts found in 30.1% of the dromedary, 5.5% of the cattle and 6.5 of the sheep. The fertility rate of hydatid cysts in humans (75% and camels (76% was significantly higher than that of sheep (24% and cattle (23% (P<0.0001. Hydatid infestation is characterized globally by the dominance of pulmonary localiza­tions in hu­mans (50% and camels (72.7% and in the liver in sheep (76.1% and cattle (82.3%.Conclusion: The differences between prevalence rates, the fertility of hydatid cysts and diversity sites localization observed in humans and camels of one hand and the sheep and cattle on the other hand, depends possibly the strain(s diversity of E. granulosus.

    Full Text Available Disc cysts are uncommon intraspinal cystic lesions located in the ventrolateral epidural space. They communicate with the nucleus pulposus of the intervertebral disc and cause symptoms by radicular compression. We report a unique case of lumbar disc cyst that was associated with disc herniation and contralateral radiculopathy. A 22 year old male presented with one month history of back-ache radiating to the left leg. Magnetic Resonance Imaging (MRI showed L3-L4 disc herniation with annular tear and cystic lesion in the extradural space anterior to the thecal sac on right side, which increased in size over a period of 3 weeks. L3 laminectomy and bilateral discectomy and cyst excision was done with partial improvement of patients symptoms.

    Three patients with roentgenographic evidence of smooth, round mediastinal mass were evaluated by computerized tomographic scanning. The density readings from these three lesions were interpreted as equivalent to solid tissues. However, thoracotomy revealed all 3 lesions were thin-walled bronchogenic cysts containing thick viscid fluids. Histological examination of the cystic walls showed no specific findings such as calcium deposits, just showing histology of the bronchial wall. Chemical analysis of the fluids was not carried out in all three cases. The cause of high CT numbers in these cysts was unclear. Diagnostically, a smooth, round mediastinal mass with high CT number in the paravertebral area medical to the head of the rib might be a bronchogenic cyst.

    Full Text Available The objective of this study was to describe a case of a lymphoepithelial cyst in the palatoglossus arch. A 16-years-old black man said that he was observed a lesion in his mouth. On the physical exam, a pedicled, consistent, smooth surface 1.5 x 1 cm lesion, similar in color to the adjacent mucosa, was found. The lesion was surgically removed and the microscopic exam showed mucosal fragments with pedicled lesion; the cystic cavity sometimes lined with pseudostratified cylindrical epithelium and others with stratified squamous flat interface of the epithelium. Around the cyst, a well-delimited mass of lymphoid tissue, presenting lymphoid follicles, was also seen. Lymphoepithelial cyst has clinical characteristics similar to those of others lesions that occur in the oral cavity. The diagnosis should be based on conservative biopsy, with total removal of lesion.

    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.

    To accurately describe patient characteristics and the clinical presentation of fatal colloid cysts. A systematic literature search of 3 popular databases was performed. Inclusion criteria were individuals with sudden-onset death and colloid cysts identified on imaging and/or autopsy. The cause of death must have been ascribed to the colloid cyst to be eligible for data extraction. Deaths precipitated by lumbar puncture were excluded. Clinical data were extracted and descriptive statistics were ascertained. Subgroup analyses were performed to compare adults with pediatric patients. A total of 107 patients were included in the quantitative synthesis. The mean age was 28.5 years (standard deviation 13.3, range 6-79 years). Male and female patients were affected equally. Headache was the most frequent symptom (n = 86, 80%). There were 6 patients (5 adults and 1 child) who reported positional headaches. The mean duration of signs and symptoms was shorter in adults versus pediatric patients (2.1 days vs. 6.5 days, P = 0.02), and more adults presented with signs and symptoms for less than 24 hours than did pediatric patients (38% vs. 6%, P = 0.01). Colloid cyst mean diameter was 2.0 cm (standard deviation 1.1, range 0.5-7.9 cm) and 96% measured 1 cm or larger. Our data suggests that the prodrome preceding sudden death in the setting of a colloid cyst may be shorter in adults. Also, most fatal colloid cysts measured 1 cm or larger. Copyright © 2017.

    1995-03-01

    Lymphoepithelial cysts are developmental, but their pathogenesis is unknown. The classical explanation is that they are derived from remnants of the branchial arches or clefts. This has been disputed, and it is likely that most arise from epithelium, possibly of tonsillar or salivary origin, that becomes entrapped by lymphoid tissue. This report describes a lymphoepithelial cyst in a 29-year-old man. The cyst was situated on the right side of the floor of the mouth adjacent to the lingual frenum. Its appearance supports both branchiogenic and the entrapment theories.

    A formerly healthy 41-year-old male with monosymptomatic swelling of his left testicle was diagnosed with testicular cancer (seminoma). During staging of the cancer a computed tomography showed left renal agenesis and an 8 x 6 cm retrovesical space-occupying lesion in the left side of the pelvis....... The lesion was interpreted as a group of enlarged lymph nodes, but PET/CT and MRI later demonstrated that it was a left seminal vesicle cyst. An association between congenital seminal vesicle cysts and ipsilateral renal agenesis is rare and can be explained by their common embryologic origin....

    Cyst of Nuck is an infrequent disease originated in the inadequate obliteration of the processus vaginalis during the embrionary life of the woman. Clinically usually appears as a slowly growth inguinal tumor, painless, smooth, soft, fluctuant and irreducible. Differential diagnosis must include inguinal hernia and other etiologies of inguinal tumor, for which echography is the main diagnostic test. Treatment consists on surgical extirpation and local reparation. It is exposed a case of a patient with cyst of Nuck clinically typical. It is made a review of clinical, diagnostic and therapeutic approach of this disease.

    Full Text Available A 35-year-old male patient presented with a right upper eyelid mass with mechanical ptosis. The patient gave no history of trauma or surgery. On examination, there was a huge cystic mass fixed to the tarsal plate. Excisional biopsy with tarsectomy was done. Histopathology sections demonstrated a keratin-filled cyst arising from the tarsus. A thorough Pubmed search did not reveal an epidermal cyst of the tarsal plate of this size which was successfully managed. The incision was made in such a way that postoperative ptosis would be avoided. Excess skin was removed during the surgery.

    When there's a diagnosis of follicular cyst. In front of lesions of advanced decay in deciduoud teeth about which is possible to presume chronical apical infection, we have to evaluate carefully the choice of treatment: pulpectomy or exodontia and the placement of a space maintainer. In this article there's a case in which a non-indicated pulpectomy was practised and caused a follicular cyst which is a menace to the formation and position of the unerupted permanent teeth. After the surgery we proceeded to exodontia and subsequently to place a space maintainer.

    The odontogenic keratocysts had traditionally been considered as a developmental odontogenic cyst. The characteristics exhibited by this pathology such as its clinical behavior, the high rate of recurrence, its association with the syndrome nevoid basal cell carcinoma, high mitotic activity shown by the epithelial lining and the presence of 'cysts daughter' in capsule of fibrous connective tissue, as well as the discovery of genetic abnormalities caused the World Health Organization (WHO) reclassified as a benign neoplasm and will use the term odontogenic keratocyst tumor to name it.

    Primary amenorrhea is a common problem. Diagnosis is usually by going through systematic approach of history, examination and investigations. This case had bilateral large endometriotic cysts in the adnexal region. Uterus was normal sized with well-formed endometrium. She underwent laparotomy followed by drainage of endometriotic cysts, stripping and reconstruction of ovaries was performed. Patient was given a trial of combined oral contraceptive pills for two consecutive cycles to observe withdrawal bleeding, but it failed. Till now we are unable to find out such case in literature. Exact case of primary amenorrhea could not be found. (author)

    Lung agenesis and gastric duplication cysts are both rare congenital anomalies. Gastric duplication cysts can present with nausea, vomiting, hematemesis, or vague abdominal pain. Unilateral pulmonary agenesis can present with respiratory distress which usually occurs due to retention of bronchial secretions and inflammations. We report the unique case of right pulmonary agenesis associated with gastric duplication cyst.

    Jaw cyst lining cells have an active transporting mechanism for Na+ ion and K+ion, a secreting mechanism and a selecting mechanism, and they allow permeation of electrolytes, lipids and protein into cysts. The components within the cysts have a controlling metabolism, and keep the system stable. Tumour wall cells of cystic ameloblastoma have only a passive transporting mechanism for various substances. Their nature differs from that of jaw cyst lining cells.

In children, simple liver cysts are described as small, asymptomatic, and rarely hemorrhagic. We report an adolescent male presenting with an unusually large hepatic cyst that did not have typical imaging characteristics. The imaging findings and histology are displayed along with the differential diagnoses of complex liver cysts.

    Full Text Available The category B agent of bioterrorism, Entamoeba histolytica has a two-stage life cycle: an infective cyst stage, and an invasive trophozoite stage. Due to our inability to effectively induce encystation in vitro, our knowledge about the cyst form remains limited. This also hampers our ability to develop cyst-specific diagnostic tools.Three main aims were (i to identify E. histolytica proteins in cyst samples, (ii to enrich our knowledge about the cyst stage, and (iii to identify candidate proteins to develop cyst-specific diagnostic tools.Cysts were purified from the stool of infected individuals using Percoll (gradient purification. A highly sensitive LC-MS/MS mass spectrometer (Orbitrap was used to identify cyst proteins.A total of 417 non-redundant E. histolytica proteins were identified including 195 proteins that were never detected in trophozoite-derived proteomes or expressed sequence tag (EST datasets, consistent with cyst specificity. Cyst-wall specific glycoproteins Jacob, Jessie and chitinase were positively identified. Antibodies produced against Jacob identified cysts in fecal specimens and have potential utility as a diagnostic reagent. Several protein kinases, small GTPase signaling molecules, DNA repair proteins, epigenetic regulators, and surface associated proteins were also identified. Proteins we identified are likely to be among the most abundant in excreted cysts, and therefore show promise as diagnostic targets.The proteome data generated here are a first for naturally-occurring E. histolytica cysts, and they provide important insights into the infectious cyst form. Additionally, numerous unique candidate proteins were identified which will aid the development of new diagnostic tools for identification of E. histolytica cysts.

    Liver cysts are divided into congenital and acquired. Congenital cystic lesions include polycystic liver disease, simple cysts, duct related and ciliated hepatic foregut cysts. Acquired cystic lesions are divided into infectious and non-infectious. The infectious cysts are the hydatid cyst, the amoebic abscess, and the pyogenic abscess, whereas the non-infectious cysts are neoplastic cysts and false cysts. While modern medicine provides a lot of minimally invasive therapeutic modalities, there has emerged a pressing need for understanding the various types of liver cysts, the possible minimal therapeutic options along with their indications and complications. We aim is to clarify the role of minimally invasive techniques in the management of hepatic cysts. A literature review was performed using the MEDLINE database. The search terms were: liver cyst, minimally invasive, laparoscopic, percutaneous, drainage and fenestration. We reviewed 82 English language publications articles, published until October 2017. Minimally invasive management of liver LC is an emerging field including many therapeutic modalities ranging from the percutaneous aspiration of pyogenic abscesses to laparoscopic hepatectomy for hepatic cystadenomas. The most used techniques are percutaneous drainage, laparoscopic fenestration, and laparoscopic hepatectomy. The application of the various minimally invasive approaches, as well as their indication and complications, depend on the type of the cystic lesion, its size and its position in the liver. Percutaneous drainage is mostly used in simple cysts, hydatid cysts, pyogenic abscesses and bilomas. Laparoscopic fenestration is mostly used in simple cysts and polycystic liver disease. Finally, laparoscopic hepatectomy is mostly used in polycystic liver disease, hydatid cysts, and cystadenomas.

    The cyst stage of Entamoeba histolytica is a promising therapeutic target against human amoebiasis. Our research team previously reported the production in vitro of Cyst-Like Structures (CLS) sharing structural features with cysts, including rounded shape, size reduction, multinucleation, and the formation of a chitin wall coupled to the overexpression of glucosamine 6-phosphate isomerase, the rate-limiting enzyme of the chitin synthesis pathway. A proteomic study of E. histolytica trophozoites, cysts, and in vitro-produced CLS is reported herein to determine the nature of CLS, widen our knowledge on the cyst stage, and identify possible proteins and pathways involved in the encystment process. Total protein extracts were obtained from E. histolytica trophozoites, CLS, and partially purified cysts recovered from the feces of amoebic human patients; extracts were trypsin-digested and analyzed by LC-MS/MS. In total, 1029 proteins were identified in trophozoites, 550 in CLS, and 411 in cysts, with 539, 299, and 84 proteins unique to each sample, respectively, and only 74 proteins shared by all three stages. About 70% of CLS proteins were shared with trophozoites, even though differences were observed in the relative protein abundance. While trophozoites showed a greater abundance of proteins associated to a metabolically active cell, CLS showed higher expression of proteins related to proteolysis, redox homeostasis, and stress response. In addition, the expression of genes encoding for the cyst wall proteins Jessie and Jacob was detected by RT-PCR and the Jacob protein identified by Western blotting and immunofluorescence in CLS. However, the proteomic profile of cysts as determined by LC-MS/MS was very dissimilar to that of trophozoites and CLS, with almost 40% of hypothetical proteins. Our global results suggest that CLS are more alike to trophozoites than to cysts, and they could be generated as a rapid survival response of trophozoites to a stressful condition

    This book presents a forecasting mechanism of the price intervals for deriving the SCR (solvency capital requirement) eradicating the risk during the exercise period on one hand, and measuring the risk by computing the hedging exit time function associating with smaller investments the date until which the value of the portfolio hedges the liabilities on the other. This information, summarized under the term “tychastic viability measure of risk” is an evolutionary alternative to statistical measures, when dealing with evolutions under uncertainty. The book is written by experts in the field and the target audience primarily comprises research experts and practitioners.

    We report a case of renal hydatid cyst in a 25-year-old male who presented with hydatiduria. Intravenous pyelography revealed presence of a space-occupying lesion in the lower pole of right kidney with curvilinear calcifications. Ultrasound, computed tomography and MRI were suggestive of hydatid cyst in the right kidney. Patient underwent right-sided nephrectomy. Passage of hydatid cysts in urine is an exceedingly rare occurrence. Urinary tract involvement develops in 2–4% of all cases of hydatid cyst. Hydatiduria is an extremely rare manifestation of renal hydatid cyst. We report such a case with emphasis on IVU, sonographic, CT and MRI findings. PMID:22470646

    Congenital urachal abnormalities are more common in children, but urachal cyst is more frequently seen in adults. Infection within a cyst produces significant symptoms, which may explain the fact that three times as many infected cysts as uninfected urachal cysts are detected in adults. We report here on a case of infected urachal cyst with a fish bone and also the fistular formation between the ileum and urachus in a 63-year-old male with a history of urinary frequency and a tender mass at the lower abdominal quadrant.

    The most common cause of echinococcosis in humans is Echinococcus granulosus. Although hydatid cyst is most frequently localized in liver (more than 65% of cases) and lung (25%) by means of portal and systemic circulation, it may involve other tissues and organs. Cardiac hydatid cysts account for only 0.5%-2% of all hydatid cysts, even in endemic areas. Of all cardiac hydatid cysts, the left ventricle accounts for 60%, right ventricle 10%, pericardium 7%, pulmonary artery 6%, left atrial appendage 6%, and interventricular septum 4%. We report the case of a myocardial hydatid cyst of the left ventricle in a 9-year-old boy. (author)

    Pericardial cysts are rare and generally benign intrathoracic lesions, most frequently located in the cardiophrenic angles, but other locations have been described. We present a case of a pericardial cyst in a previously undescribed site. Our patient presented with a cyst in the interventricular septum which was discovered as an incidental finding. After surgical excision of the cyst, it was described pathologically as a simple mesothelial pericardial cyst. The explanation of this rare condition is uncertain, but some hypotheses can be outlined. Copyright © 2016 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U.

    Large adrenal cysts usually occur in the fifth and sixth decades of a patient's life but are rare in the first two decades. This paper presents the clinical, cross-sectional imaging, surgical, pathological and follow-up data of three teenage girls with large adrenal cysts. Two had vague upper abdominal pain and, in the other, the cyst was found incidentally. The cysts were surgically removed in two patients, while in the third, follow-up imaging has shown no change in the cyst over a 4-year period, suggesting that conservative management is a reasonable option.

    Full Text Available Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. There is usually no pain or discomfort associated with the cyst unless there is acute inflammatory exacerbation. Management of dentigerous cyst in primary dentition needs special consideration regarding the preservation of the developing permanent tooth buds. Here, we report a case of dentigerous cyst in primary dentition in a 10-year-old male patient and its management.

    Full Text Available Purpose: We report a case of iris pigment epithelial cysts in a newborn and discuss the importance of an accurate diagnosis for prevention of amblyopia.Methods: We describe a case of an abnormal red reflex seen on a newborn exam.Results: A full-term female born via normal spontaneous vaginal delivery without any complications was seen in the newborn nursery. She was noted to have an abnormal eye exam. Pupils were large with circular dark excrescences of the iris pigment epithelium. She was referred to a pediatric ophthalmologist where she was noted to fixate and follow faces. No afferent pupillary defect was seen. OD red reflex was normal whereas OS red reflex was blocked mostly by dark excrescences. A 2– dark brown lesion was seen in the OD iris and a 3–5 mm dark brown lesion was seen in the OS iris, consistent with a pupillary iris pigment epithelial cyst. Central visual axis was clear OU. Glaucoma was not present and patching was not performed. Observations and clinical photographs were recommended with follow-up in three months.Conclusion: Iris pigment epithelial cysts are uncommonly seen in children. The primary care provider first seeing a newborn must be aware of lesions obscuring a red reflex with appropriate follow-up. Follow-up in three months with IOP measurements is recommended. Iris pigment epithelial cysts in children may be a cause of amblyopia, thus prompt evaluation is important for prognostic purposes and the prevention of amblyopia.

Patients presenting with pancreatitis were older when compared to the non-pancreatitis group (5.1 vs. 1.2 years, P = 0.005). Nine out of 16 (53%) patients with Type IV-A cysts presented with pancreatitis compared to five (33%) of Type I fusiform and three (17%) of Type I cystic. There was however no statistically significant association between Todani types and the development of pancreatitis (Type I fusiform, P = 1.0; Type I cystic, P = 0.063; Type IV-A, P = 0.053). The rate of complications was similar in both groups. Pancreatitis was a common presentation in children with a choledochal cyst, however, there was no clear statistically significant association with Todani types and pancreatitis. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    2014-07-01

    Full Text Available Background. Choledochal cyst is a rare abnormality. Its esti- mated incidence is of 1:100,000 to 150,000 live births. Todani et al. in 1981 reported the main objection for performing a simpler procedure, i.e., hepaticoduodenostomy, has been the risk of an “ascending cholangitis”. This hazard, however, seems to be exaggerated. Methods: A laparoscopic procedure was performed in 8 consecutive patients with choledochal cyst between January 2010 and Septem- ber 2012; 6 females and 2 males mean age was 8 years. Results. Abdominal pain was the main symptom in everyone, jaundice in 1 patient and a palpable mass in 3 patients. Lapa- roscopic surgical treatment was complete resection of the cyst with cholecystectomy and hepaticoduodenostomy laparoscopy in every patient. Discussion and conclusion. A laparoscopic approach to chole- dochal cyst resection and hepaticoduodenostomy is feasible and safe. The hepaticoduodenal anastomosis may confer additional benefits over hepaticojejunostomy in the setting of a laparoscopic approach. The creation of a single anastomosis can decrease operative time and anesthetic exposure.

    We present our experience in the management of choledochal cysts from 1999 to 2009. A retrospective review of all charts with a diagnosis of choledochal cysts in our institution in this ten-year period. Data was collated using Excel. A total of 17 patients were diagnosed with choledochal cyst: 9 females and 8 males. The average age at diagnosis was 28 months (range from 0 to 9 years). The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

    Full Text Available Dermoid and epidermoid cysts in the oral cavity frequently develop in the midline or sublingual region of the floor of the mouth. Here, we report a rare case of an epidermoid cyst in the submandibular region. The patient was a 69-year-old man with a chief complaint of a mass in the right submandibular region. A mobile, elastic, relatively soft mass without tenderness was palpable in this region. The skin covering the mass was normal. MRI showed a cystic lesion measuring 3.5 × 3.0 cm under the platysma in the right submandibular region. Cystectomy was performed under general anesthesia. There was no adhesion to surrounding tissue and the right submandibular gland was preserved. The surgical specimen was cystic and contained soybean cord-like materials. Histopathologically, the cyst wall was lined by stratified squamous epithelium with no skin appendage, suggesting an epidermoid cyst. The postoperative course was uneventful and without recurrence after 28 months.

    Epidermoid cyst is a benign and rare tumor, that evolves slowly. We describe the case of a 55 years-old woman, who came to our consultation for atypical trigeminal neuralgia of left V1 and V2 nerves. Brain MRI found two tumors: T1W hypointense with no appreciable enhancement after gadolinium injection and T2W and diffusion hyperintense. This last feature was in favour of an epidermoid cyst, but the multiplicity of cerebral lesions was definitely not in favor of such a diagnos­tic. They were located behind the right eye and in the left Meckel’s cave (trigeminal cave). The surgical strategy consis­ted in removal the retro orbital tumor witch was the most acces­si­ble of both the diagnostic of epidermoid cyst was retaned thanks to the anatomopathology report. As these lesions had the exact same characteristics, we concluded that they were simi­lar. The second epidermoid cyst was not removed because of surgical risk, its benign nature and low evolutionary potential.

    We discussed six cases with dorsal cyst malformations listing their neuroradiological observations and proposed to differentiate between the holosphere and hemisphere as defined by Yokota (1984). The cases were divided into holospheric and hemispheric groups depending on the continuity of their frontal lobe midlines. Cases 1, 2 and 3 were placed in the holospheric group because of their unseparated frontal lobe sbeneath the partially formed anterior interhemispheric fissures. Cases 4, 5 and 6 were grouped in the hemisphere due to the completion of the interhemispheric fissures. There has been a tendency in recent years for most cases of cerebral malformations having an endogenous dorsal cyst with monoventricular configuration to be diagnosed as holoprosencephaly. However, we believe that only patients who have a dorsal cyst in the holospheric brain should be included, and the others in the hemispheric brain, which is capable of completing hemispheric cleavage, should not. Therefore, we emphasize the importance of correctly identifying the holospheric state in the dorsal cyst malformations for diagnosing holoprosencephaly. (author)

    Cervical thoracic duct cysts are a rare anomaly. To report a case of cervical thoracic duct cyst, and perform a literature review. A 78-year-old female, with a one-year history of a left-sided asymptomatic supraclavicular cystic mass. Computerized tomography revealed a cystic mass 42mm in diameter. We performed a fine needle aspiration puncture, obtaining a thick, milky, whitish liquid. The patient underwent surgery; finding a left-sided supraclavicular cystic mass, with some lymph vessels heading towards the jugulo subclavian venous junction. We performed a ligation of these lymph vessels and resection of the mass. The histopathologic study confirmed the diagnosis of thoracic duct cyst. Diagnosis of cervical thoracic duct cyst should be suspected with a cystic lesion in the left supraclavicular region, which when perforated exudes a very distinctive thick milky, whitish liquid with a high content of lymphocytes and triglycerides. Treatment should be complete removal with ligation of the lymphatic afferent vessels. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    Splenic cysts are rare lesions with around 800 cases reported in the world literature. Traditionally splenectomy was the treatment of choice. However, with the recognition of the important immunological function of the spleen, new techniques to preserve splenic function have been developed. This case emphasizes that in selected cases splenic preservation is appropriate.

    Objective: To analyze the characteristics of spinal meningeal cyst in low-field MRI and to discuss its classification, subtype, clinical presentation, and differential diagnosis. Methods: Forty-two patients (20 male, 22 female) were examined with sagittal T 1 -and T 2 -, axial T 2 -weighted MR imaging. Twelve patients were also examined with contrast-enhanced MRI. Results: The cysts were classified using Nakors' classification as type Ia extradural meningeal cysts (4 patients), type Ib sacral meningeal cysts (32), type II extradural meningeal cysts with spinal nerve root fibers (4), and type III spinal intradural meningeal cysts (2). All 42 spinal meningeal cysts had well-defined boundaries with low T 1 and high T 2 signal intensities similar to cerebral spinal fluid. In type Ia, the lesions were often on the dorsum of mid-lower thoracic spinal cord compressing the spinal cord and displacing the extradural fat. In type Ib, the lesions were in the sacral canal with fat plane between the cyst and dural sac. In type II, the lesions contained nerve roots and were lateral to the dural sac. In type III, the lesions were often on the dorsum of spinal cord compressing and displacing the spinal cord anteriorly. Conclusion: Low-field MRI can clearly display the spinal meningeal cyst. Types Ia and Ib spinal meningeal cysts had typical features and can be easily diagnosed. Types II and III should be differentiated from cystic schwannomas and enterogenous cysts, respectively.

    2012-01-01

    Acute bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worsening confusion over a 3-week period. Brain CT scan findings were highly suggestive of a third ventricular colloid cyst with intraventricular rupture. He underwent cyst excision and histopathology, which confirmed the radiological diagnosis with evidence of haemorrhage within the cyst. A ventriculo peritoneal shunt was performed for delayed hydrocephalus. Surgical management of these patients must include emergency ventriculostomy followed by prompt surgical removal of the haemorrhagic cyst.

    2013-01-01

    Three cases of symptomatic extradural arachnoid cyst were treated by surgery. Total excision of the cyst followed by tight closure of the fistula by suture was achieved in all 3 cases. Surgery improved the neurological deficits but urinary incontinence persisted in all three patients. Obliteration of the fistula is considered to be important at surgery from the etiological perspective of the cyst. There are many surgical options, but surgical removal of the cyst and obliteration of the communication usually leads to prompt improvement in neurological deficits. Instability, malalignment, and worsening scoliosis are well-recognized postoperative complications of excessive laminotomy, but the exposure should be wide enough to cover the cyst completely at the operation. Wide exposure of the entire cyst is preferable to avoid missing the fistula and to identify any adhesions or fistula between the cyst and the dura. Identification of the fistula location based on preoperative imaging studies is also important.

    Full Text Available Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopathological similarities. Materials and methods. In this cross-sectional, analytical study the subjects were 22 ameloblastomas, 13 dentigerous cysts, 10 keratocystic odontogenic tumors (KCOT, 4 adenomatoid odontogenic tumors (AOT, 3 orthokeratinized odontogenic cysts, 3 calcifying odontogenic cysts (COC and one glandular odontogenic cyst (GOC. All the samples were examined for CD56 immunoreactivity. Data were analyzed using chi-square test. Results. Twenty cases (91% of ameloblastomas, 3 (75% AOT, 4 (40% KCOT and one case of GOC were positive for CD56. None of the dentigerous cysts, COC and orthokeratinized odontogenic cysts was CD56-positive. There was a significant difference in the CD56 expression between ameloblastoma and dentigerous cyst, as well as COC. Also, KCOT showed significantly higher expression than orthokeratinized odontogenic cyst. Conclusion. In this study CD56 expression was limited to the odontogenic tumors and more aggressive cystic lesions. This marker can be a useful aid for distinguishing cysts and tumors from similar lesions.

    In the present study, we sought to: (a) analyze the p53 gene status in dentigerous cysts (DC) associated with supernumerary teeth (ST) in a pair of siblings with ST, of whom one developed a DC; and (b) conduct a narrative review of the literature on ST associated with DC. Blood samples were obtained, and the isolated DNA was used to amplify exons 4-8 of the p53 gene using specific primers, and subsequently sequenced. No mutations were identified in the coding regions of the p53 gene. A review of the literature revealed a prevalence of DC associated with ST to be as high as 13.6%, and that 83% of the case reports performed enucleation of DC and removal of ST. Dentigerous cysts associated with ST in one sibling demonstrated that variations in phenotypes exist, and the absence of mutations cannot eliminate the potential influence of genetic risk factors. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available Abstract Background: Resistance of Acanthamoeba cysts causes recurrence of the disease; so, the patient should be monitored regularly ،The aim of the study was to examine the effect of a few herbal materials on Acanthamoeba cysts in vitro. Materials and Methods: Essential oils (EOs of Zataria, Mint, and Oregano were prepared by steam distillation. The EOs and Hypericum perforatum extract were prepared in three concentrations (0.6%, 1% and 10%، Acanthamoeba cysts in various time intervals (30, 60, 120, 180 and 1440 minutes were exposed with plant extracts. Then, the viability of parasite was investigated by eosin 0.1%. Results: Comparison of the parasite mortality rate between control and case groups showed that the mortality of Acanthamoeba cysts was higher in the case groups that exposed to herbal materials. At the equal concentration (10% and time (24 h, the Zataria and mint EOs produced the highest (22% and lowest (4% mortality, respectively. The results showed the mortality rate of Acanthamoeba was time-dependent. Conclusion: Zataria showed the most fatality effect against Acanthamoeba cysts. In this respect, clinical trial studies are suggested.

    Using carcinoembryonic antigen in discriminating between benign and malignant disease remains controversial. We aim to evaluate the diagnostic accuracy of cyst fluid carcinoembryonic antigen in predicting malignant pancreatic cystic lesions. We performed a literature search of MEDLINE and EMBASE. We included studies that compared the diagnostic accuracy of carcinoembryonic antigen with histology. Pooled estimates of diagnostic precision were calculated using random-effects models. Eight studies (504 patients) were included. The carcinoembryonic antigen cutoff level for determining a malignant cyst ranged from 109.9 to 6000 ng/mL. Pooled estimates of carcinoembryonic antigen in malignant cysts prediction were poor: pooled sensitivity of 63%, pooled specificity of 63%. The positive likelihood ratio was 1.89 and the negative likelihood ratio was 0.62. The diagnostic odds ratio was 3.84. The area under the summary receiver-operating characteristic curve was 0.70. In subgroup analysis of patients with mucinous cysts (mucinous cystic neoplasm and intraductal papillary mucinous neoplasm; 5 studies, 227 patients), pooled sensitivity was 65%, pooled specificity 66% and diagnostic odds ratio 4.74 respectively. This meta-analysis suggests that the accuracy of carcinoembryonic antigen in differentiating "between benign and malignant" pancreatic cysts was poor. The decision to perform surgical resection for pancreatic cystic lesions should not be based solely on carcinoembryonic antigen level. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l.

    Both symptomatic Rathke's cleft cyst and intrasellar abscess are exceedingly rare. We present a case of intrasellar abscess developed in a Rathke's cleft cyst. A 60-year-old man was admitted to our hospital with complaints of polyuria, polydipsia, headache, and remittent fever. On admission, his neurological and ophthalmological examination was normal. Panhypopituitarism was revealed by endocrine testing. Plain-skull X-ray films showed no abnormalities, but a CT scan showed a small cystic lesion with a ring-like enhancement in the sella turcica and paranasal sinusitis. Further sagittal reconstruction of the CT scan demonstrated that the diaphragma sellae protruded upwards and that the pituitary stalk was markedly enhanced and enlarged. After the sinusitis improved, transsphenoidal surgery was carried out. Approximately 1 ml of the purulent contents were aspirated from the intrasellar region. The postoperative course was uneventful. A histological examination of the abscess wall revealed a ciliated columnar epithelium and inflammatory-cell infiltration beneath the epithelium. (author)

    Full Text Available Background: Echinococcosis or hydatidosis, caused by the larval stage of Echinococcus granulosus (E. granulosus, is an important public health problem in many areas of the world  and  Iran is a country of endemic situation for hydatidosis In the present study, we evaluated epidemiological, complications and clinical characteristics of hydatidosis at three University Medical Centers in Tehran over a 10-year period.Materials and Methods: This is a descriptive cross-sectional study performed in patients with hydatid cysts. Information about age, gender, number of cysts, organ involvement, morbidity and mortality and relapse were collected from medical records of hydatid patients. Paraclinic information such as CT Scan, MRI, ultrasound, complete blood count, pathological diagnosis and complication of disease were collected.Results: Overall, 81 patients, 35 (43.2% male and 46 (56.8% female, who were diagnosed as having hydatid cyst by clinical and radiological findings, with pathologic documentation were studied in three university medical center registries over a 10-year period (2003- 2012 in Tehran. Fourteen patients (17% of cases had complications resulting from this disease. Patients' age ranged from 5 to 86 years, and the peak prevalence of the disease was between 20 and 40 (34% of cases.Conclusion: Iran  is a country of endemic situation for hydatidosis. Prevalence rate of hydatidosis in Iran was reported to be 0.61-2 in 100000 populations. The highest  rate of infection and complications were in patients of 20-40 years age. Clinical examination revealed that abdominal pain was the most common complaint and was present in 51.7% of the cases. Other most common complain were cough, abdominal mass, dyspnea, icterus, chest pain, dyspepsia, back pain and seizure; and it was result of occupying effect of cysts in organs. This is similar with previous studies in Iran

  13. Spiniferites cruciformis: a fresh water dinoflagellate cyst?

    Kouli, K; Brinkhuis, H; Dale, B

    2001-04-01

    Palynological studies of cored lacustrine sediments from the late Quaternary of Lake Kastoria, northern Greece, revealed a Late Glacial interval with abundant dinoflagellate cysts. Cyst assemblages include two identifiable species, Spiniferites cruciformis and Gonyaulax apiculata. The presence of the fresh water species G. apiculata is consistent with the lacustrine setting of these deposits, but that of S. cruciformis is anomalous. Previously, this species has only been recorded in abundance from presumed brackish marine sediments from the Black Sea and Marmara Sea sediments where geochemical data clearly record brackish salinities. Therefore, it has been regarded as a low salinity cyst type with a wide range of morphological variation that some workers have suggested to reflect salinity fluctuations. Specimens from Greece display only part of the range of morphological variability previously described from these (brackish) marine settings. Encountered morphological variation includes ellipsoidal/pentameral and cruciform endocyst shapes with rare intermediate shapes, and highly variable septa development. Specimens characterized by extremely reduced ornamentation known from (brackish) marine environments have not been recorded. Our records of S. cruciformis indicate that: (1) it could thrive in fresh water conditions; and (2) that apparently most of the strong morphological variations of the cysts are an intrinsic phenomenon for this taxon, and may only partly be linked to salinity variations as suggested earlier. We suggest that S. cruciformis essentially is a fresh water taxon, and that its records in (brackish) marine environments, with the exception of specimens with strongly reduced ornamentation, may be due to transportation, to short-lived fresh water surface conditions in such environments, or to tolerance of the species to brackish conditions.

    Traumatic bone cyst is a pathologic cavity that is not lined with epithelium. It is, therefore, not a true cyst. It may be a normal variant rather than a disease process. The etiology of the condition is unknown. This condition is occurred widely ranging ages(2 to 75 years), however, most are found during the second decade of life. Radiographically, this condition is radiolucent lesion with well-defined outline, scalloping of superior margins. Cyst enucleation and curettage is the treatment of choice. The authors compared and analyzed the clinicoradiologic features of the five cases of traumatic bone cyst, diagnosed at the Dental college hospital in Chosun University, Kwangju, Korea. The five cases were shown the followed results; 1. 3 cases occurred in second decade of life and no significant sex differences (M:F, 2:3) All cases occurred in mandible. 2. Two patients complained symptoms, but three cases had no symptom with encountering during routine examination. 3. In 3 of 5 cases, teeth vitality existed except one tooth and no checking of teeth vitality in two cases. 4. All cases didn't have any accurate trauma history, but one case was in orthodontic treatment, another case was postextraction site area. 5. Radiologically, 'scalloping appearance' were evident in all cases; in 3 cases, multilocular tendency and only one case seen intact mandibular canal image. 6. Histologically, all section showed bone trabeculae with ballistic activity, 2 cases showed no epithelial lining, and other 2 cases were seen inflammatory cell infiltration in edematous tissue. 7. Surgical intervention (curettage) was that treatment of choice.

  18. The Toxoplasma gondii cyst wall protein CST1 is critical for cyst wall integrity and promotes bradyzoite persistence

    Toxoplasma gondii infects up to one third of the world’s population. A key to the success of T.gondii is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. We have identified CST1 (TGME49_064660) as a 250 kDa SRS (SAG1 related sequence) domain protein with a large mucin-like domain. CST1 is responsible for the Dolichos biflorus Agglutinin (DBA) lectin binding characteristic of T. gondii cysts. Deletion of CST1 results in a fragile brain cyst phenotype revealed by a thinning and disruption of the underlying region of the cyst wall. These defects are reversed by complementation of CST1. Additional complementation experiments demonstrate that the CST1-mucin domain is necessary for the formation of a normal cyst wall structure, the ability of the cyst to resist mechanical stress and binding of DBA to the cyst wall. RNA-seq transcriptome analysis demonstrated dysregulation of bradyzoite genes within the various cst1 mutants. These results indicate that CST1 functions as a key structural component that reinforces the cyst wall structure and confers essential sturdiness to the T. gondii tissue cyst.

    A case of a ruptured dermoid cyst presenting headaches and dizziness as the only symptoms is presented. A 60-year-old woman was admitted to our hospital after complaining of headaches for 5 years and of dizziness for 1 week. The results of physical and neurological examinations were normal. An X-ray of the skull revealed an intracranial calcification in the left frontal region. CT disclosed calcification and a large low-density area in the left parasellar region and the frontal lobe. The mass consisted of two different areas of density. There were multiple, isolated, low-density spots in the left Sylvian fissure and the interpeduncular cistern. No abnormal enhancement was seen by CECT. Angiograms showed an elevation of the A 1 portion of ACA and a lateral shift of MCA. A left fronto-temporal craniotomy was performed. Chronic or past leptomeningitis was suspected because of the arachnoid-membrane thickening. Multiple fatty globules were present in the left Sylvian fissure. A large, soft, fatty tumor was completely removed. The histologic diagnosis was a dermoid cyst. After this operation, the headaches and dizziness were reduced. It is unclear whether the headaches were caused by the compression of the tumor or by the meningeal irritation of the fatty debris. According to the findings on the arachnoid membrane, however, it seems likely that fatty debris detached from the tumor spilled out intermittently from the cyst into the subarachnoid space, resulting in meningeal irritation.

    Full Text Available Introduction. Epidermoid inclusion cysts are usually composed of epidermal elements implanted into the dermal layers. Patients are seen in the outpatient clinics with a mass. Most of the complaints are mechanical and cosmetic problems. Case Outline. A 34-year-old female patient was admitted to our clinic because of swelling and pain in her right foot. A palpable mass was detected in the first web. On the x-rays of the foot no osseous lesion was detected. There was a soft tissue mass in the first web according to MRI report. Soft tissue mass was excised and sent to pathology. According to pathology report the mass was an epidermoid cyst 5Ч2Ч1.5 cm in size. There were no problems during follow-up of the patient for 6 months after surgery. The patient had no swelling in the foot and had no additional complaints on checkup. Conclusion. In the differential diagnosis, we should take into consideration epidermoid cyst of large soft tissue masses of the foot. Surgical excision should be done within the appropriate limits.

    A young soldier was brought to the emergency of Combined Military Hospital (CMH), Multan in a collapsed state with two day's history of chest pain. He was resuscitated and placed on ventilator. While the rest of examinations were normal, ultrasound examination of the abdomen revealed a cystic mass in liver most likely to be hydatid. The patient was fully conscious the next day and was put on tab albendazole (200 mg BID). CT scan of the abdomen revealed a large cystic mass having inner undulating wall with watery content diagnosed as hydatid cyst in right lobe of liver. Since anaphylaxis was considered consequent to hydatid cyst perforation, surgery was carried out. Approximately 100 ml of haemorrhagic fluid was aspirated and 10% hypertonic saline instilled. After re-aspiration, cyst cavity was opened and endocyst completely removed. Portion of ectocyst projecting away from the liver edge was also excised. He made an uneventful postoperative recovery and was discharged with the advice to continue tab albendazole 200mg BID for four weeks and weekly follow-up in surgical OPD. He is doing well now.

    Extradural arachnoid spinal cysts are unfrequent lesions that are associated with spinal trauma, surgery and less frequently with congenital anomalies. The clinical manifestations are similar to those seen with other compressive spinal cord lesions. Magnetic resonance techniques allow to diagnose correctly this pathology and to define its thopographic situation. The pathologic history of the patient is essencial to establish the ethiology. Surgery is the elective treatment in most cases. The patient is a 35 years old man who has a medical history of penetrating spinal trauma two years ago. In that instance he suffered an unilateral spinal cord section at D2-D3 level with the corresponding Brown Sequard syndrome. A small wound was detected at the skin dorsal level and it was closed without difficulties. At the beginning, he improved his motor right leg function with rehabilitation and vitamins. After two years of good recovery he came to our hospital suffering a neurological deterioration of six months of evolution. The physical examination revealed an spastic paraparesis. Magnetic resonance was performed demonstrating a cystic extradural collection compressing the spinal cord at D3-D4 level. Surgical decompressive treatment allowed to excise the cyst and it was possible to define a dural tear that was closed successfully. The outcome was good with restoration of the initial motor function that he had after the spinal trauma. Surgical management of postraumatic epidural arachnoid spinal cyst allows to detect the meningeal tear and to close it, which is highly effective on these kinds of lesions.

    Case report. We report a rare case that a ganglion cyst compressed the sciatic nerve and caused sciatica and claudication in a 51-year-old male. Sciatica and claudication commonly occurs in spinal stenosis. To our knowledge, only 4 cases have been reported on sciatica resulting from posterior ganglion cyst of hip. A 51-year-old male had a 2-month history of radiating pain on his right leg. He could only walk 20 to 30 m before stopping and standing to rest for 1 to 3 minutes. Interestingly, he was able to walk longer distances (about 200 m) when walking slowly in small steps, without any rest. He had been treated as a case of lumbar disc herniation, but conservative treatment was ineffective. On buttock examination, a round, hard, and fixative mass was palpated at the exit of the sciatic nerve. MR imaging of hip revealed a multilocular cystic mass located on the posterior aspect of the superior gemellus and obturator internus, compressing the sciatic nerve. On operation, we found that the cyst extended to the superior gemellus and the obturator internus, positioned right at the outlet of the sciatic nerve. At 18 months of follow-up, the patient continued to be symptom free. He returned to comprehensive physical activity with no limitations. For an extraspinal source, a direct compression on the sciatic nerve also resulted in sciatica and claudication. A meticulous physical examination is very important for the differential diagnosis of extraspinal sciatica from spinal sciatica.

    Full Text Available Paediatric penile cysts are uncommon. We report a five-year-old child with an asymptomatic progressively growing cyst on the ventral aspect of the penis after a hypospadias repair. The patient presented to the Cooper Health Clinic, Dubai, United Arab Emirates, in March 2012. A complete excision of the cyst was performed. Histology results delineated a capsulated benign trichilemmal cyst. No recurrence or complications were reported in the 26 months following the excision. We recommend an early and complete excision of all penile cysts to prevent the risk of urethral obstruction, infection, inflammation and rare malignant changes. This is the first reported case of a penile trichilemmal cyst in a child.

    Splenic cysts are relatively uncommon, and are usually asymptomatic. They are benign, typically treated conservatively and followed up with ultrasound examination, with few reported complications. We report a case of a simple splenic cyst that was followed up on imaging over a seven-year period. During that time, the cyst gradually enlarged from 5 cm to 12 cm in diameter, however the patient remained asymptomatic. After seven years, the patient was admitted with abdominal pain and a pelvic mass. The spleen was located within the pelvis, which was felt to be due to the weight of the cyst which caused the spleen to migrate out of its normal position. This case illustrates an extremely unusual complication, and suggests that while most splenic cysts may be managed conservatively, enlarging cysts may be prone to gravitational effects and prophylactic treatment should be considered.

    To describe the US findings of corpus luteum cyst rupture in order to elucidate the associated clinical features. Twenty patients with proven corpus luteum cyst rupture were included in this study. The US findings of these patients were retrospectively analyzed in terms of the presence of designable cyst, size of the cyst, thickness and blood flow of the cyst wall, extension and echogenicity of peritoneal fluid, and involved site (right or left ovary). We also surveyed the clinical features such as the onset period according to the menstrual cycle, and the presence of suspectable cause. Fourteen of the 20 patients revealed designable cysts (mean diameter of 2.6 cm) with thick walled cysts (mean thickness, 4.6 mm, 2.4-6.8 mm) and increased blood flow. Six patients didn't reveal any cyst but only hematoma in adnexa. All patients had hemoperitoneum in the pelvic cavity, and the hemoperitoneum was extended to Morrison's pouch in 8 patients and to the subphrenic space in 6. The cysts occurred in the right adnexa in 15 patients and in the left in 5. Mean interval from the last menstrual period (LMP) was 26 days (13-44 days) and 6 of the 8 patients for whom it had been possible to obtain detailed history taking had had coitus just before the occurrence of symptom. When women who are hospitalized for acute abdomen and who are in luteal phase reveal US findings of hematoma or thick-walled cyst in adnexa and hemoperitoneum, a corpus luteum cyst rupture is highly suspected. In our case study the corpus luteum cyst rupture predominantly occurred in the right side, and the most suspectable cause was trauma such as coitus in the luteal phase

    Scrotum's sebaceous cyst is an usual pathology, not life threatening, but susceptible of infection, producing abscess with their associated cosmetic and psychological disturbance. The classical management is the complete excision, under local anaesthesia, to prevent its recidive. Until today, the use of de Nd-YAG laser for the management of the scrotum's sebaceous cysts as not been reported. We report a case of a young man with several scrotum's sebaceous cysts, treated successfully with the use of a Nd-YAG laser.

The approach to be followed in the case of this extremely rare disease is briefly discussed, underlining that the present is the third such case to date reported in the literature.

  19. Economic viability of anaerobic digestion

    Energy Technology Data Exchange (ETDEWEB)

    Wellinger, A. [INFOENERGIE, Ettenhausen (Switzerland)

    1996-01-01

    The industrial application of anaerobic digestion is a relatively new, yet proven waste treatment technology. Anaerobic digestion reduces and upgrades organic waste, and is a good way to control air pollution as it reduces methane and nitrous gas emissions. For environmental and energy considerations, anaerobic digestion is a nearly perfect waste treatment process. However, its economic viability is still in question. A number of parameters - type of waste (solid or liquid), digester system, facility size, product quality and end use, environmental requirements, cost of alternative treatments (including labor), and interest rates - define the investment and operating costs of an anaerobic digestion facility. Therefore, identical facilities that treat the same amount and type of waste may, depending on location, legislation, and end product characteristics, reveal radically different costs. A good approach for evaluating the economics of anaerobic digestion is to compare it to treatment techniques such as aeration or conventional sewage treatment (for industrial wastewater), or composting and incineration (for solid organic waste). For example, the cost (per ton of waste) of in-vessel composting with biofilters is somewhat higher than that of anaerobic digestion, but the investment costs 1 1/2 to 2 times more than either composting or anaerobic digestion. Two distinct advantages of anaerobic digestion are: (1) it requires less land than either composting or incinerating, which translates into lower costs and milder environmental and community impacts (especially in densely populated areas); and (2) it produces net energy, which can be used to operate the facility or sold to nearby industries.

    A pineal cyst is a benign affection of the human pineal gland on the borderline between pathology and normality. Only a small percentage of patients present with symptoms and a surgical treatment is indicated in highly selected cases. A melatonin secretion in patients with a pineal cyst before and after a pineal cyst resection has not been studied yet and the effect of surgery on human metabolism is unknown. The present study examined melatonin, cortisol and blood glucose secretion profiles perioperatively in a surgical group of 4 patients. The control group was represented by 3 asymptomatic patients with a pineal cyst. For each patient, 24-h circadian secretion curves of melatonin, cortisol and glycemia were acquired. An analysis of melatonin profiles showed an expected diurnal pattern with the night peak in patients before the surgery and in the control group. In contrast, melatonin levels in patients after the surgery were at their minimum throughout the whole 24-h period. The cortisol secretion was substantially increased in patients after the surgery. Blood glucose sampling showed no statistically significant differences. Clinical results demonstrated statistically significant headache relief measured by Visual Analogue Scale in patients after the surgery. Despite the small number of examined patients, we can conclude that patients with a pineal cyst preserved the physiological secretion of the hormone melatonin while patients who underwent the pineal cyst resection experienced a loss of endogenous pineal melatonin production, which equated with pinealectomy. Surprisingly, cortisol secretion substantially increased in patients after the surgery. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2005-01-01

    Purpose. This paper presents a modification of the known method for percutaneous treatment of hydatid cyst, the PAIR technique. It aimed to achieve safe aspiration of large symptomatic cysts and cysts with a danger of impending rupture. Methods. We designed a coaxial catheter system to achieve concomitant evacuation of cyst contents while infusing scolicidal agent. Hypertonic saline is used to wash out cyst contents and to kill protoscolices. This was followed by injection of a sclerosant (ethyl alcohol 95%) into the residual cyst cavity to prevent formation of a cyst collection after the procedure. Seventeen cysts in 14 patients were successfully aspirated. Follow-up plain radiographs, ultrasonography and CT were performed weekly in the first 4 weeks and then at 3, 6 and 12 months for all patients. Seven patients (9 drained cysts) were followed up for 2 years and 1 patient for 3 years. Results. All cysts were successfully aspirated. The following morphologic changes were noticed: a gradual decrease in cyst size (17 cysts, 100%), thickening and irregularity of the cyst wall due to separation of endocyst from pericyst (7 cysts, 41%), development of a heterogeneous appearance of the cyst components (8 cysts, 47%) and development of pseudotumor (2 cysts, 12%). None of the treated cysts disappeared completely. No significant procedure-related complications were encountered. Conclusion. This modified PAIR technique is a reliable method for percutaneous treatment of risky and symptomatic hydatid cysts

    2017-12-01

    Objective Laryngeal cysts may occur at any mucosa-lined location within the larynx and account for 5% to 10% of nonmalignant laryngeal lesions. A number of proposed classifications for laryngeal cysts exist; however, no previously published classification aims to guide management. This review analyzes contemporary laryngeal cyst management and proposes a framework for the terminology and management of cystic lesions in the larynx. Data Sources PubMed/Medline. Review Methods A primary literature search of the entire Medline database was performed for all titles of publications pertaining to laryngeal cysts and reviewed for relevance. Full manuscripts were reviewed per the relevance of their titles and abstracts, and selection into this review was according to their clinical and scientific relevance. Conclusion Laryngeal cysts have been associated with rapid-onset epiglottitis, dyspnea, stridor, and death; therefore, they should not be considered of little significance. Symptoms are varied and nonspecific. Laryngoscopy is the primary initial diagnostic tool. Cross-sectional imaging may be required, and future use of endolaryngeal ultrasound and optical coherence tomography may revolutionize practice. Where possible, cysts should be completely excised, and there is growing evidence that a transoral approach is superior to transcervical excision for nearly all cysts. Histology provides definitive diagnosis, and oncocytic cysts require close follow-up. Implications for Practice A new classification system is proposed that increases clarity in terminology, with the aim of better preparing surgeons and authors for future advances in the understanding and management of laryngeal cysts.

    2017-10-01

    Full Text Available Theca lutein cysts can occur in 20-25% of molar pregnancies. These cysts can undergo complications such as torsion, rupture, and haemorrhage. As these are functional cysts, when there are complications such as torsion they can be managed conservatively by aspirating the cysts under ultrasound guidance or by detorsion at the time of laparoscopy. By simple detorsion, ovaries can be preserved in 80-90% of cases. In order to prevent recurrence adnexal fixation can be undertaken by plicating the ovarian ligament.

    Six patients with acquired spinal subarachnoid cysts secondary to epidural anesthesia were evaluated with MR imaging (seven patients) and intraoperative US (three patients). The cysts were located in the lower cervical and thoracic spine. Adhesions and irregularity of the cord surface were frequently noted. Associated intramedullary lesions, including intramedullary cysts and myelomalacia, were seen in two of the patients. Arachnoiditis was unsuspected clinically in three patients, and MR imaging proved to be the diagnostic examination that first suggested the cause of the patients symptoms. The underlying mechanism for the formation of these cysts is a chemically induced arachnoiditis

    Full Text Available Cardiac hydatid cyst is rare and usually occurs in the setting of disseminated disease. Herein, we reported a case of isolated right atrial hydatid cyst misdiagnosed clinically as a tumor. A 65-year-old woman diagnosed as having large right atrial mass suspected of malignancy underwent resection of the cardiac mass. Histopathological examination showed laminated membrane and protoscolices of Echinococcus Granulosus. However, all other work-ups failed to document systemic diseases. Therefore, isolated cardiac hydatid cyst was diagnosed. Hydatid cysts should be considered in differential diagnosis of any cardiac mass, especially in endemic areas.

    2011-01-01

    Cysts of Naegleria fowleri present an external single-layered cyst wall. To date, little information exists on the biochemical components of this cyst wall. Knowledge of the cyst wall composition is important to understand its resistance capacity under adverse environmental conditions. We have used of a monoclonal antibody (B4F2 mAb) that specifically recognizes enolase in the cyst wall of Entamoeba invadens. By Western blot assays this antibody recognized in soluble extracts of N. fowleri cysts a 48-kDa protein with similar molecular weight to the enolase reported in E. invadens cysts. Immunofluorescence with the B4F2 mAb revealed positive cytoplasmic vesicles in encysting amebas, as well as a positive reaction at the cell wall of mature cysts. Immunoelectron microscopy using the same monoclonal antibody confirmed the presence of enolase in the cell wall of N. fowleri cysts and in cytoplasmic vesicular structures. In addition, the B4F2 mAb had a clear inhibitory effect on encystation of N. fowleri. © 2011 The Author(s). Journal of Eukaryotic Microbiology © 2011 International Society of Protistologists.

    Full Text Available Popliteal cyst commonly presents as an ellipsoid mass with uniform low signal intensity on T1-weighted magnetic resonance images and high signal intensity on T2-weighted images. Here, we describe a popliteal cyst with unusual appearance on magnetic resonance imaging, including heterogeneous intermediate signal intensity on T2-weighted images. Arthroscopic cyst decompression revealed that the cyst was filled with necrotic synovial villi, indicative of rheumatoid arthritis. Arthroscopic enlargement of unidirectional valvular slits with synovectomy was useful for the final diagnosis and treatment.

    A 63-year-old male presented with a round-shaped floater and visual obscuration in the right eye. Clinical evaluation showed a nonpigmented vitreous cyst connected to a lattice degeneration by a stalk. Immunostaining of the vitreous cyst obtained from vitrectomy showed its origin of retinal neuroepithelium. The cyst was formed by continuous vitreous traction, which might tear up the disrupted retina at the area of lattice degeneration. This report added the lattice degeneration to the list of causes for the acquired vitreous cyst. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:856-858.]. Copyright 2017, SLACK Incorporated.

    Full Text Available Hydatid cyst disease is a parasitic infection caused by Echinococcus granulosus . Hydatid cyst disease is endemic in our country. This disease is most commonly detected in the liver and lung. Primary soft tissue involvement is very rare, causing a diagnostic challenge. Turkey is an endemic area for hydatid cyst disease and we should bear this disease in mind as a differential diagnosis in all cystic lesions. In this study, we mentioned a hydatid cyst case in gluteus maximus muscle without any primary lesion.

    Cyst adenocarcinoma of the salivary glands is a very rare, slow growing, and low-grade malignant neoplasm. It is characterized by predominantly cystic growth with or without the intraluminal papillary component. However, it lacks of any additional specific histopathologic features that characterize other types of salivary carcinomas showing cystic growth. Therefore, definite diagnosis of the cyst adenocarcinoma is difficult and it is often misdiagnosed. It is conceptually the malignant counterpart of the benign cyst adenoma. We present a cyst adenocarcinoma on the palate of a 49-year-old man with special emphasis on magnetic resonance imaging.

    This study describes the pathological changes associated with an experimental infection of captive wallabies with Echinococcus granulosus. Adult and juvenile tammar wallabies (Macropus eugenii) were infected orally with 0, 1,000, 2,500 or 8,000 E. granulosus eggs. Lung cyst progression was monitored by chest radiography every 4 months until 16 months p.i. Animals were necropsied from 9 to 16 months after infection. Cysts were detected radiographically from 4 months onwards. The number of cysts per animal varied from one to 10 and the majority (36/40) of cysts established in the lungs. Infection rate was low (35.5%), but cyst development was more rapid and onset of fertility much earlier than has been recorded in sheep. Cyst growth resulted in loss of functional lung capacity, up to an estimated 28% within 14 months of infection. Degenerative changes in cysts were less common in tammars than has been reported in sheep, with gross degeneration of cysts identified in only two animals. Complications associated with lung cyst development included fatal anaphylaxis, pneumothorax and atelectasis. Seven of the 11 infected tammars died or were euthanased as a result of infection during the experiment. From the parasite's perspective, infection of this host allows a shortened life cycle and correspondingly greater biotic potential. We believe this is the first published study that demonstrates the susceptibility of tammar wallabies to hydatid disease and confirms their suitability as a laboratory model for studying the disease in macropodids.

    Despite their names, simple bone cysts are no longer categorized as cysts since they lack an epithelial lining. However, their nature remains controversial. The internal structure is totally radiolucent, sometimes showing multilocular appearance, although the lesion does not contain true septa and the ridges of bone is produced by the scalloping effect. We presented two cases of histopathologically confirmed simple bone cyst. Radiographic features such as multilocular appearance and significant buccal and lingual expansion are not usual findings for simple bone cyst, whereas evident in our presented cases.

    Full Text Available Objective. To describe an atlantoaxial degenerative cyst associated with instability. Animal. Chihuahua, male, 5 years old. Methods. Ever since colliding with a large dog two years prior to presentation, the dog suffered recurrent episodes of intractable cervical pain. Over time, the pain attacks increased in frequency and intensity. On presentation, pain was clinically localized to the high cervical region. No neurological deficits were observed. CT and MRI revealed an atlantoaxial degenerative articular cyst associated with instability, causing cervicomedullary compressive myelopathy. On MRI the cyst appeared hypointense in T1W and hyperintense in T2-weighted sequences, with rim enhancement. The dog was treated surgically by cyst fenestration and ventral stabilization using a 1.5 mm Butterfly Locking plate and cancellous bone graft placed within the atlantoaxial joint after cartilage removal. Histological examination of a sample of the cyst wall confirmed a degenerative articular cyst. The dog recovered uneventfully after surgery and remained pain free throughout the 2-year followup. Conclusion. Atlantoaxial degenerative articular cyst associated with instability is a rare finding in dogs. Clinical Relevance. The presence of an atlantoaxial degenerative articular cyst appears not to worsen the prognosis of instability treatment. Atlantoaxial fusion and cyst fenestration may provide good long-term results.

    Full Text Available Parathyroid cysts constitute 0.08–3.41% of all parathyroid masses. Intrathyroidal parathyroid cysts, however, are rare conditions with only a few cases being reported. Most of the parathyroid cysts are found to be nonfunctional and functional cysts are generally thought to be due to cystic degeneration of parathyroid adenomas. A cystic, smooth contoured lesion of 24 × 19 × 16 mm was observed in left thyroid lobe of a 76-year-old woman during ultrasonography which was performed as routine workup for primary hyperparathyroidism. It was defined as a cystic thyroid nodule at first. Tc99m sestamibi scintigraphy was performed to see any parathyroid lesions, but no radioactive uptake was observed. Intact parathormone (iPTH level was found to be >600 pg/mL in cyst aspiration fluid. Left lobectomy was performed, with a diagnosis of primary hyperparathyroidism due to functional parathyroid cyst. Serum iPTH level was decreased >50% postoperatively and histopathological evaluation was consistent with an encapsulated parathyroid adenoma with a cystic center. Parathyroid cysts are among rare causes of primary hyperparathyroidism. Diagnosis is made by markedly increased iPTH level in cyst fluid and observation of parathyroid epithelium lining the cyst wall.

    Full text: 24 hour 201 TI reinjection imaging improves myocardial viability detection when compared to standard 3-4 hour redistribution imaging, however, it is a time-consuming approach and some images do not provide adequate quality due to high background activity on the delayed scan. We tested whether sensitivity of redistribution and same day reinjection imaging could be improved by giving short-acting nitrates immediately prior to redistribution and reinjection imaging. Eighteen patients underwent a stress test (exercise or pharmacological) and 4 hour redistribution 201 TI SPECT study. Immediately after redistribution imaging, each patient was given 600 μg of sublingual glyceryl trinitrate and reimaged 15-20 minutes later (nitrate augmented image). Immediately following nitrate augmentation imaging, each patient was reinjected with 30 MBq of 201 TI and reimaged 20 minutes later (nitrate augmented reinjection images). Each patient returned 24 hours later and was reinjected with 40 MBq of 201 TI and imaged 20 minutes later (24 hour reinjection images). In all, each patient had five SPECT images as follows: stress/redistribution/ nitrate augmented redistribution/nitrate augmented same day reinjection/ 24 hour reinjection. The myocardium was divided into 11 segments and perfusion to each segment was scored by consensus method (2 blinded assessors) on a 4 point graded scale (0 = no perfusion, 1 = minimal perfusion, 2 = moderate perfusion, 3 = normal perfusion). Perfusion scores were analysed on a segment by segment basis; as well, each patient was given an overall perfusion score equal to the sum of the perfusion score for each segment. 150 segments with reduced perfusion were identified, of these 23 (15.3%) showed improvement in the redistribution images, 60 (40%) segments improved in the nitrate augmented images, 49 (32.7%) improved in the nitrate augmented reinjection images and 52 (34.7%) improved in the 24 hour reinjection images.

    Full Text Available Dentigerous cyst is the most commonly occurring odontogenic cyst after radicular cyst and accounts for 15% of all true cysts in the jaws. The cyst is more common in mandible than in maxilla. The dentigerous cyst is commonly associated with impacted mandibular third molars. In maxilla, the incidence is rare. Dentigerous cyst in maxillary sinus in association with an impacted third molar is an uncommon entity. We present a case of dentigerous cyst associated with an impacted third molar, completely obliterating the maxillary sinus in a 28-year-old female.

    Full Text Available Background. Differentiating branch duct from mixed intraductal papillary mucinous neoplasm (BD-IPMN is problematic, but clinically important as mixed IPMNs are managed surgically, while some BD-IPMN may be followed. Inflammatory mediator proteins (IMPs have been implicated in acute and chronic inflammatory and malignant pancreatic diseases. Aim. To compare IMP profile of pancreatic cyst fluid collected endoscopically from BD-IPMN and mixed IPMN. Methods. Pancreatic cyst fluid from ten patients (5 BD-IPMN and 5 mixed IPMN was collected by endoscopic ultrasound-guided fine needle aspiration or endoscopic retrograde cholangiopancreatography. Concentrations of 89 IMPs in these samples were determined using a multiplexed bead-based microarray protein assay and compared between BD-IPMN and mixed IPMN. Results. Eighty-six of 89 IMPs were detected in at least one of the 10 samples. Fourteen IMPs were detected only in mixed IPMN, while none were only in BD-IPMN. Of these, TGF-β1 was most prevalent, present in 3 of 5 mixed IPMNs. Seventy-two IMPs were detected in both BD-IPMN and mixed IPMNs. Of these, only G-CSF (P<0.05 was present in higher concentrations in mixed IPMNs. Conclusion. TGF-β1 and G-CSF detected in endoscopically collected pancreatic cyst fluid are potential diagnostic biomarkers capable of distinguishing mixed IPMN from BD-IPMN.

    Echinococcus granulosus is a cestode parasite. The metacestode stage causes cystic echinococcosis (CE) mainly in the human liver and lung. Current chemotherapy against CE is based on mebendazole and albendazole. However, benzimidazoles result in a low cure rate or are ineffective in many patients; therefore, novel compounds for the treatment of this disease have been studied. Mefloquine was reported to be dramatically effective on cultured Echinococcus multilocularis metacestodes in vitro. And, nitazoxanide has a prominent protoscolicidal effect. However, these compounds have no impact on the growth of cysts harbored in mice. In this study, we investigated the in vitro and in vivo efficacy of mebendazole, mefloquine, and nitazoxanide against E. granulosus protoscoleces, germinal cells, and infected mice. The effect of mebendazole on protoscoleces and germinal cell was proved to be dose-dependent in vitro. And, a reduction of the cyst weight was also the found after oral application of mebendazole to infected mice. Mefloquine (5 and 10 μg/ml) caused death within 24 h of protoscoleces and germinal cells in vitro, whereas a lower concentration of 1 μg/ml was ineffective. In mice infected with E. granulosus, oral mefloquine (200 and 400 mg/kg twice weekly for 2 weeks) showed no reduction in parasite weight. Without affecting the viability of germinal cells and the growth of hydatid cysts, nitazoxanide only showed protoscolicidal effects in infected mice. In conclusion, mebendazole, mefloquine, and nitazoxanide showed various effects on E. granulosus under different conditions. These drugs could be useful to some extent in the treatment of CE.

    Sarcocystosis is a zoonotic disease caused by Sarcocystis spp. with obligatory two host life cycle generally alternating between an herbivorous intermediate host and a carnivorous definitive host. Some species of this coccidian parasite can cause considerable morbidity and mortality in cattle. The present study was set to investigate the prevalence of Sarcocystis spp. and type of cyst wall in slaughtered cattle of Karaj abattoir, Iran. For this purpose 125 cattle (88 males and 37 females) were investigated for the presence of macroscopic and microscopic Sarcocystis cysts in muscular tissues. No macroscopic Sarcocystis cysts were found in any of the samples. In light microscopy, 121 out of 125 cattle (96.8 %) had thin-walled cysts of Sarcocystis cruzi, while 43 out of them (34.4 %) had thick-walled Sarcocystis cyst. In this survey, the most infected tissue was esophagus and heart and the less was diaphragm. Thin-walled cysts (S. cruzi) mostly found in heart and skeletal muscle showed the less. However, thick-walled cyst (S. hominis or S. hirsuta) mostly were detected in diaphragm, heart muscle showed no thick-walled cyst. No significant relation was observed between age and sex and the rate of infection. The results showed that Sarcocystis cyst is prevalent in cattle in the North part of Iran and the evaluation of infection potential can be useful when considering control programs.

    Full Text Available Lymphoepithelial cyst (LEC is the most commonly encountered congenital neck pathology in the lateral part of the neck. A 66-year-old woman presented to the ENT clinic due to difficulty in swallowing persisting for approximately 1 year. Magnetic resonance imaging revealed a cystic mass at right tonsil. Surgery was performed due to this unilateral tonsillar mass, which was excised together with the right tonsil. LEC was diagnosed at histopathological examination. LEC in the palatine tonsil is rare, and only a few cases have been reported in the literature. We report a rare case of LEC in the palatine tonsil.

    A patient is presented with widespread primary hydatid cysts in spinal-paraspinal locations, secondary to Echinococcus granulosus. An alternative mechanism to explain how the embryos gained access to the body is proposed: The embryos penetrated the intestinal muscle and may have directly entered into the inferior vena cava system through small venous connections between this system and portal circulation. Various conditions in daily life associated with Valsalva maneuver might have caused such an atypical passage of the embryos to the inferior caval system toward the retroperitoneum and spinal-paraspinal structures via lumber epidural venous plexuses.

    Twelve cases of subchondral synovial cysts (intra-osseous ganglion) have been seen and their clinical features, radiological findings and differential diagnosis are described. The lesion is a benign cystic tumour-like mass in the subchondral portion of a synovial joint. Our findings in respect of age, sex and localisation are compared with those of other authors. The aetiology and pathogenesis of the lesion is not completely understood. There is an increased incidence in middle life and joints with high dynamic and static stress are favoured, particularly in the lower extremities. Chronic stress or microtrauma, causing damage to the involved joint, therefore appears to be a plausible explanation. (orig.) [de

    We report two children who presented with multiple renal cysts involving only one kidney and in whom there was no family history of renal disease and who did not have syndromes known to be associated with renal cystic disease. This unilateral involvement may represent a distinct entity, which has only been previously described in three cases; however, long-term follow-up will be needed to confirm this hypothesis. We illustrate the sonographic and computed tomographic findings, and the differential diagnosis is discussed. (orig.)

    A 20-year old woman with a 2-month history of epigastric pain, progressive jaundice and obstructive liver biochemistry underwent imaging of the biliary tract, carried out using ultrasonography, CT-scan and MRI. Abdominal ultrasound showed a dilation of the choledochal duct. CT-scan and MRI revealed a cystic dilation of the choledochal duct. Because of possible malignant degeneration, en-bloc cholecystectomy and resection of the cyst were performed, with Roux-en-Y hepaticojejunostomy reconstruction. This case demonstrates the diagnostic value of MRI and MRCP in a pathology that is rather rare in Western countries.

  17. A contribution to the diagnosis of the small dentigerous cyst or the paradental cyst

    2001-01-01

    Full Text Available The aim of this study was to verify the relationship between the radiographically measured width of the pericoronal space (PS and the microscopic features of the follicle in order to contribute to the diagnosis of small dentigerous cysts and paradental cysts. One hundred and thirty unerupted teeth (UT and thirty-five partially erupted teeth (PET were radiographed and extracted. The radiographic analysis consisted of measuring the width of the PS. The results of the radiographic analysis were compared with those of the histopathologic examination of the dental follicle. The width of the PS ranged from 0.1 to 5.6 mm. The most frequently observed lining of the follicles was a reduced enamel epithelium (REE (68.4% in UT and a hyperplastic stratified squamous epithelium (HSSE (68.5% in PET. Inflammation was present in 36.1% of the UT and in 82.8% of the PET. There was a statistically significant association between the presence of stratified squamous epithelium (SSE and PS enlargement for UT (p < 0.05. There was a tendency of association between inflammation and PS enlargements in PET and, possibly, in UT, despite the absence of statistical significance. Surgically, we did not detect bone cavitation or luminal cystic contents in pericoronal spaces smaller than 5.6 mm. We suggest that the first radiographic diagnosis for a PS enlargement, in most of the routine clinical cases, should be of "inflammation of the follicle". The hypothesis of "dentigerous cyst" or "paradental cyst" is suggested as a second diagnosis. The final differential diagnosis between a small dentigerous or a paradental cyst and a pericoronal follicle depends on clinical and/or surgical findings, such as the presence of bone cavitation and cystic content.

    Advanced wastewater treatment processes are applied to prevent the environmental dissemination of pathogenic microorganisms. Giardia lamblia causes a severe disease called giardiasis, and is highly prevalent in untreated wastewater worldwide. Monitoring the microbial quality of wastewater effluents is usually based on testing for the levels of indicator microorganisms in the effluents. This study was conducted to compare the suitability of fecal coliforms, F+ coliphages and sulfide reducing clostridia (SRC) as indicators for the reduction of Giardia cysts in two full-scale wastewater treatment plants. The treatment process consists of activated sludge, coagulation, high rate filtration and either chlorine or UV disinfection. The results of the study demonstrated that Giardia cysts are highly prevalent in raw wastewater at an average concentration of 3600 cysts/L. Fecal coliforms, F+ coliphages and SRC were also detected at high concentrations in raw wastewater. Giardia cysts were efficiently removed (3.6 log 10 ) by the treatment train. The greatest reduction was observed for fecal coliforms (9.6 log 10 ) whereas the least reduction was observed for F+ coliphages (2.1 log 10 ) following chlorine disinfection. Similar reduction was observed for SRC by filtration and disinfection by either UV (3.6 log 10 ) or chlorine (3.3 log 10 ). Since F+ coliphage and SRC were found to be more resistant than fecal coliforms for the tertiary treatment processes, they may prove to be more suitable as indicators for Giardia. The results of this study demonstrated that advanced wastewater treatment may prove efficient for the removal of Giardia cysts and may prevent its transmission when treated effluents are applied for crop irrigation or streams restoration.

  9. Pancreatic cyst development: insights from von Hippel-Lindau disease

    Full Text Available Abstract Pancreatic cysts are a heterogeneous group of lesions, which can be benign or malignant. Due to improved imaging techniques, physicians are more often confronted with pancreatic cysts. Little is known about the origin of pancreatic cysts in general. Von Hippel-Lindau (VHL disease is an atypical ciliopathy and inherited tumor syndrome, caused by a mutation in the VHL tumor suppressor gene encoding the VHL protein (pVHL. VHL patients are prone to develop cysts and neuroendocrine tumors in the pancreas in addition to several other benign and malignant neoplasms. Remarkably, pancreatic cysts occur in approximately 70% of VHL patients, making it the only hereditary tumor syndrome with such a discernible expression of pancreatic cysts. Cellular loss of pVHL due to biallelic mutation can model pancreatic cystogenesis in other organisms, suggesting a causal relationship. Here, we give a comprehensive overview of various pVHL functions, focusing on those that can potentially explain pancreatic cyst development in VHL disease. Based on preclinical studies, cilia loss in ductal cells is probably an important early event in pancreatic cyst development.

  6. A rare presentation of lower back swelling as tailgut cyst

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Retrorectal cystic hamartoma, also known as tailgut cyst, is a rare congenital developmental lesion arising from postnatal primitive gut remnants in the retrorectal space. The rarity of the lesion and its anatomical position usually leads to difficulty in diagnosis and surgical management. This cyst predominantly occurs in women (female to male ratio, 3:1. Tailgut cysts can present as incidental findings during the routine examination but over half of the patients are thought to present with symptoms. Computed tomography or magnetic resonance imaging has a crucial role in diagnosing these misdiagnosed cysts. Complete surgical excision is the treatment of choice for tailgut cysts as this provides a definitive diagnosis, relieves symptoms, and prevents possible complications such as infection, fistula formation, and malignant degeneration. We present a case of a 40-year-old female, who presented to us with lower back swelling (7 cm × 5 cm for last 2 years, which had become more prominent to her while sitting. The patient was investigated. Ultrasonography demonstrated ill-defined large cystic lesion (8 cm × 7 cm, posterior to the uterus. Fine needle aspiration cytology suggested sebaceous cyst. A lumbosacral contrast-enhanced computed tomography demonstrated well-defined fluid density mass/collection with enhancing walls in the retrorectal, presacral, precoccygeal area, and suggested tailgut duplication cyst/retrorectal cystic hamartoma. Surgical complete excision of the cystic mass was done with both anterior (transabdominal and posterior approach. Histopathology confirmed a tailgut cyst.

    2015-03-01

    Full Text Available Several types of intraspinal cyst develop within the spinal canal from the craniovertebral junction to the sacrum. These lesions occur in both children and adults. Arachnoid cysts are one of them and are more frequent in the paediatric population, being a relatively uncommon lesion in adults. The arachnoid cyst may be located intradurally or extradurally. The intradural type may be congenital or from spinal trauma, infection or spondylosis. Although intradural arachnoid cysts are often asymptomatic, they may give early symptoms when they exist with synchronous pathologies constricting the spinal canal gradually as in cervical spondylosis.  In this report, a 60-year-old man with an arachnoid cyst of the cervicothoracic spine is presented. His cyst remained undiagnosed because of the nonspecific nature of the symptoms. It was only when he developed right hemiparesis that a posterior fluid collection compressing the spinal cord was found in Magnetic resonance imaginig. An intradural extramedullary cyst was removed with successful surgery and cord compression and symptoms were reversed. We discuss radiological diagnosis and surgical treatment of an arachnoid cyst in this report.

    2010-10-01

    Full Text Available Introduction & Objectives: Zoonotic parasites are large groups of zoonoses among which the most important are hydatid cyst, liver trematodes and sarcocystis.These zoonoses are of considerable importance regarding both human health and economy. The objective of this study was to determine the prevalence of tissue zoonotic parasites and their epidemiologic status in Hamadan and to estimate the health and medical burden they impose on the society.Materials & Methods: In this cross sectional study, viscera (including liver, lung, kidney, heart,… and muscles of 2590 sheep, 420 cattle, and 490 goats were macroscopically inspected for hydatid cysts, liver flukes, cysticercus , and microscopically (for Sarcocystis in the Hamadan abattoir. The data were presented by descriptive tables and analyzed by 2 statistical test. Results: The infection rate for hydatid cyst, Fasciola, Dicrocoelium and Sarcocystis were found 12.3%, 4.9%, 6.5%, and 5.5% respectively. The high infection rates for hydatid cyst and Fasciola were found in cattle (16.2% and 9.5% and for Dicrocoelium and Sarcocystis were found in sheep (6.9%. Infection rate of lungs was higher (41.2% than liver (36.6% and liver and lung simultaneously were 22.2% in the infected animals. Infection to Sarcocystis and Cysticercus were not found in the cattle. Conclusion: This study indicated that infection rate of tissue zoonotic parasites are relatively high in the domestic animals of Hamadan , however, the rate is lower in comparison to the previous studies. These parasites had imposed considerable economic burden on the society through reduction in the dairy production and increased the risk of infection in the population as well.

    2007-03-01

    Full Text Available Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. When observed with erupted and complete dentition the diagnosis is a surprise; as about 95% of dentigerous cysts involve the permanent dentition and only 5% are associated with supernumerary teeth. The usual age of clinical presentation of dentigerous cyst due to supernumerary tooth is during the first four decades. Mesiodens is a supernumerary tooth situated between the maxillary central incisors. More frequently the mesiodens occurs unilaterally, but it may also be bilateral, while three or more supernumerary teeth in the median region of the palate are more rarely found. We report a rare case of dentigerous cyst in association with multiple mesiodens in a 14-year-old female patient.

    The authors have interpreted one patient's full mouth intra-oral films, oblique-lateral film of the left mandible and orthopantomograph which revealed 6 radicular and 1 residual cysts. As results of interpretation of these serial films, we have drawn following conclusions: 1. Radicular cyst arose from the cell rests contained in an apical granuloma which was sequel to advanced pulpitis due to dental caries. 2. Radicular cyst was developed from remaining cell rests after the extraction of a tooth with such a radicular cyst of apical dental granuloma. 3. Cyst grew in size by absorption of fluid into cystic cavity due to difference in osmotic pressure between the cystic fluid and adjacent tissue fluid.

    2008-01-01

    Ciliated hepatic foregut cyst is the only ciliated cystic lesion known to occur in the liver. It is an extremely rare, benign and solitary cyst that probably arises from remnants of the embryonic foregut in the liver. We report a 16-month-old girl who underwent surgical excision of a hepatic cyst discovered during antenatal ultrasonography. Surgical exploration and excision were performed because of the uncertain aetiology of the cyst and because on postnatal follow-up US the size of the mass had increased causing extrinsic biliary obstruction. Pathology revealed a ciliated hepatic foregut cyst. This is the fourth child affected by this lesion reported in the literature, the second undergoing surgical excision, and the second with antenatal diagnosis. (orig.)

    We report a case of renal hydatid cyst in a 25-year-old male who presented with hydatiduria. Intravenous pyelography revealed presence of a space-occupying lesion in the lower pole of right kidney with curvilinear calcifications. Ultrasound, computed tomography and MRI were suggestive of hydatid cyst in the right kidney. Patient underwent right-sided nephrectomy. Passage of hydatid cysts in urine is an exceedingly rare occurrence. Urinary tract involvement develops in 2-4% of all cases of hydatid cyst. Hydatiduria is an extremely rare manifestation of renal hydatid cyst. We report such a case with emphasis on IVU, sonographic, CT and MRI findings.

    Holinger, L.D.; Torium, D.M.; Anandappa, E.C.

    1988-01-01

    The congenital subglottic hemangioma typically appears as an asymmetric subglottic narrowing or mass on frontal neck radiograph. Therefore, soft tissue neck radiography has been advocated as a definitive non-operative approach for diagnosing these lesions. However, we have noted similar asymmetric subglottic narrowing in patients with acquired subglottic cysts. These retention cysts occur following long-term intubation in the neonate. The mechanism probably involves subglottic fibrosis which obstructs glands with subsequent cyst formation. Acquired subglottic cysts typically appear as an asymmetric narrowing on frontal or lateral soft tissue neck radiographs. These lesions may produce airway compromise but are effectively treated by forceps or laser removal. Acquired subglottic cysts must be included in the differential diagnosis of asymmetric subglottic narrowing. The definitive diagnosis is made by direct laryngoscopy, not soft tissue neck radiograph.

    2013-01-01

    Full Text Available Epidermoid cysts are slow- growing, benign tumors that result from proliferation of epidermal cells within a confined space. Epidermoid cysts of the eyelid typically present during adolescence through adulthood as a solitary, elevated, round, freely mobile subcutaneous mass with smooth overlying skin. The most common site for the sebaceous or epidermoid cysts is the meibomian glands of the upper tarsus due to retention of meibomian gland material. We report a case of a 32- year- old male who presented with chief complains of painless swelling on the right upper lid since 1 year. It was an extrameibomian site, i.e., at the lateral superior aspect of the eyelid. It is a rare site for the epidermoid cyst to grow to such an extent. The lesion was excised completely, and histopathology confirmed the diagnosis of epidermoid cyst.

  8. Imaging of meniscal cyst of the knee in three cases

    1989-01-01

    Three cases of solitary meniscal cyst in the knee have recently been diagnosed in our departments using ultrasound and nuclear magnetic resonance (MRI). Two cysts involved the lateral and one the medial meniscus. The appearance of these lesions on ultrasound and MR images is shown. All three cysts had low intensity on T1-weighted images and high intensity on T2-weighted images and clearly communicated with a large horizontal tear in the meniscus. Ultrasonography showed a relatively hypoechoic lesion and, in the two cases of lateral meniscal cyst, focal areas of relatively increased echoes which are probably due to meniscal debris. Ultrasound showed the abnormal meniscus in both of these cases. MRI is the best way of showing the cyst and an accompanying meniscal tear but, where MRI is not available, ultrasound may be an easy and inexpensive way of making a diagnosis whether or not it is used in conjunction with positive contrast arthrography.

    The cyst of Entamoeba histolytica is responsible for amebiasis infection. However, no axenic in vitro system exists that promotes mass encystation for studying this process of this human-infecting parasite. Cyst-like structures of E. histolytica obtained in this work were induced using TYI-S-33 media in combination with enterobacterias Escherichia coli and Enterococcus faecalis conditioned media, high CO2 tension and histamine. Cyst-like structures showed the same characteristics of a typical E. histolytica cyst: aggregation, resistance to 0.15% sarcosyl for 10 min, high signal of fluorescence under UV light when stained with 10% calcofluor M2r and the surface topology showed a wrinkled wall. In addition these structures are multinucleated with condensed chromatin attached to nuclear membrane, contain big vacuoles and ribonucleoproteic helices in the cytoplasm and also present a thin cell wall. Last all characteristics are all the same as a typical of E. histolytica cyst.

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

    Calcaneal bone cysts with pathological fractures are rare. There is no clear consensus on their management with a few reports of open curettage, bone grafting and internal fixation in the treatment of pathological calcaneal fractures. No minimally invasive management has been reported before. We reviewed our experience in treating five patients with pathologic calcaneus fractures associated with pre-existing bone cysts who underwent percutaneous cyst curettage, fracture reduction, screw fixation and calcium sulfate cement injection between 2004 and 2009. All of the pathologic fractures healed with satisfactory radiological results. There were no soft tissue complications or cyst recurrences. Partial weightbearing with plaster cast immobilization was allowed at 4 weeks postoperatively and full weightbearing was allowed at 6 weeks postoperatively. This percutaneous technique provided a minimally invasive option for treatment of a calcaneal bone cyst with pathologic fracture.

    The nasolabial cyst is defined as nonodontogenic soft tissue lesion, rare and with occurrence in sagittal plane, between midline and nasal cartilage. Because its soft tissue composition, there is no radiographic presentation in conventional radiographic examination, being indicated evaluation through computed tomography and magnetic resonance imaging. In the present study, two cases are discussed, being one in white female subject, 72-year-old, and other in a black male subject, 24-year-old. The authors discuss about relevant aspects related to differential diagnosis through computed tomography and magnetic resonance imaging, as well as atypical features founded in one of the cases, like bilateral occurrence with different signal intensity in magnetic resonance imaging and determinant factors for differential diagnosis of soft tissues pathologies of maxillofacial complex, as fissure cysts with central occurrence (sagittal cysts), as dermoid cysts, palatine and nasopalatine and lateral fissure cysts.

    Synovial cysts in an intraspinal location, associated with facet joint osteoarthritis, have been diagnosed using CT. Surgical removal of the cyst, when believed to be the cause of radiculopathy, has resulted in symptomatic relief. The authors have applied a nonoperative treatment method consisting of CT-guided needle placement in the facet joint adjacent to the cyst, followed by injection of contrast material and corticosteroids. Three patients were treated without complications and with complete relief of symptoms in two cases and partial relief in one, although no decrease in the size of the cysts was demonstrated on follow-up CT scans. The preliminary results indicate a possible role for this treatment technique in patients with intraspinal synovial cysts

    Full Text Available In May 1993, surface sediment samples from the west coast of the Iberian Peninsula were collected with the aim of studying the geographic distribution of G. catenatum resting cysts. The sampling area ranged from 40º 39´ N (Portugal to 42º 38´ N (Galicia, Spain. Cysts with exactly the same morphology as G. catenatum were found in a maximum concentration of 504 cysts.cm-3 of sediment. Similar cysts but smaller (24-36 µm were found in a maximum concentration of 4488 cysts.cm-3 of sediment. A bimodal size distribution of microreticulate cysts from the sediment indicates the probable existence of two cyst species. Differences in the microreticulation of the paracingulum were also observed. We compared the cysts from the sediment with G. catenatum cysts produced in cultures. The study on the distribution of cysts in the sediment also showed significant differences in the vertical profile concentrations of both cyst types. Differences in both the size and microreticulation morphology of the cysts found in the sediment of the continental shelf of Galicia and Portugal are also observed in the literature concerning other countries. The cysts of this species cited for the coasts of Northern Europe present characteristics similar to the cysts referred to in this communication as G. catenatum-like or small microreticulate cysts. The need to clarify the identity of cysts with microreticulation in the wall is discussed in order to identify the geographical distribution of the G. catenatum cyst.

    Thyroid cysts are rare in cats and poorly documented. To report distinguishing clinical features and treatment responses of cats with thyroid cysts. Forty client-owned cats. Retrospective review of medical records for cats with thyroid cysts confirmed by scintigraphy, ultrasound, magnetic resonance imaging, or necropsy at 4 referral centers between 2005 and 2016. Signalment, clinical findings, diagnostic testing, treatment, and outcome were recorded. Cats ranged in age from 8 to 20 years with no apparent breed or sex predilection. 37 of 40 (93%) cats were hyperthyroid (duration, 1-96 months). Clinical findings included palpable neck mass (40/40, 100%), weight loss (15/40, 38%), dysphagia (8/40, 20%), decreased appetite (5/40, 13%), and dyspnea (4/40, 10%). Cysts were classified as small (≤8 cm 3 ) in 16 (40%) and large (>8 cm 3 ) in 24 (60%) cats. Of 25 cats treated with radioiodine, hyperthyroidism resolved in 23 (92%), whereas thyroid cysts resolved in 12 (50%). Radioiodine treatment resolved small cysts in 8 of 13 (62%) cats and large cysts in 4 of 11 (36%) cats. Eight cats, including 2 euthyroid cats, underwent thyroid-cystectomy; 3 with bilateral thyroid involvement were euthanized postoperatively for hypocalcemia. Excised cystic thyroid masses were identified as cystadenoma (4) and carcinoma (4). Thyroid cysts are encountered in hyperthyroid and euthyroid cats with benign and malignant thyroid tumors. Radioiodine treatment alone inconsistently resolved thyroid cysts. Thyroid-cystectomy could be considered in cats with unilateral thyroid disease or when symptomatic cysts persist despite successful radioiodine treatment of hyperthyroidism.

    Full Text Available BACKGROUND Trichilemmal cysts or pilar tumours are slow growing scalp lesion commonly found in elderly women. These slow growing lesions may cause morbidity and even mortality. Recurrence of the lesions after local excision is common. These trichilemmal cyst usually indolent with benign nature or may transform to proliferating trichilemmal cyst or Proliferating Pilar Tumour (PPT or may show malignant transformation. The aim of the study is to study the radiological and pathological evaluation of trichilemmal cysts of scalp. MATERIALS AND METHODS A hospital-based cross-sectional retrospective study was conducted. The study group comprised of 20 patients presenting to the Departments of Radiodiagnosis, Radiotherapy, General Surgery, Plastic Surgery and Dermatology in a tertiary care hospital from July 2015 to August 2017. All patients were initially evaluated clinically followed by cross-sectional imaging modality like Computed Tomography (CT or Magnetic Resonance Imaging (MRI. RESULTS In 20 patients, a total of 51 trichilemmal cysts were evaluated where 46 (90.2% were benign trichilemmal cysts and 5 (9.8% showed malignant transformation. The mean age of presentation was 47.9 yrs. ± 1.5 (SD with male:female ratio of 1:3.The mean duration of presence of trichilemmal cyst was 5.9 yrs. ± 3.2 (SD. Out of 5 malignant trichilemmal cysts 3 patients (15% showed bony calvarial erosion and 2 patients (10% showed intracranial extensions. Statistical significance with ‘p’ value of 0.003 was noted between the size of largest dimension of trichilemmal cyst and their histopathology without any statistical significance between duration of swelling and their histopathology. CONCLUSION Even though, the trichilemmal cysts of scalp are denoted as benign lesion, as they usually shows recurrence and its affinity to become locally aggressive and turn into malignancy is there. Hence, clinical, radiological and pathological correlation isnecessary to decreased

    Although heterotopia of pancreatic tissue is a developmental anomaly found in approximately 2% of all autopsies, pancreatic tissue within the thorax and mediastinum is uncommon. In most of these instances, the pancreatic acini and islets are components of gastroenteric duplication cysts, intralobar pulmonary sequestrations, or teratomas. We describe the clinicopathologic features and hormonal profile of a patient with an anterior mediastinal cyst formed entirely by pancreatic tissue. To our knowledge, the English literature reveals only two previous examples of this lesion. The patient, a previously healthy 16-year-old girl, was found to have a cystic lesion in the anterior mediastinum during investigation of an asymptomatic heart murmur. The lesion measured 12 cm in maximal diameter and contained dark, turbid fluid. The wall was fibrotic and contained a haphazard mixture of ducts, exocrine acini, and islets. In many areas, the ducts and islets formed ductuloinsular complexes resembling those seen in diffuse nesidioblastosis. Immunohistochemical examination showed that the islets contained an increased number of B and PP cells, recapitulating the hormonal profile of the ventral anlage of the fetal pancreas. The similarity between this lesion and a fetal pancreas was further supported by the presence of a significant number of islet cells containing gastrin. The histogenesis of this lesion is unclear; we think that this lesion represents a derivative of the ventral (anterior) primitive foregut, but unidirectional differentiation of a benign cystic teratoma cannot be excluded.

    Five viruses were previously discovered infecting soybean cyst nematodes (SCN; Heterodera glycines) from greenhouse cultures maintained in Illinois. In this study, the five viruses [ScNV, ScPV, ScRV, ScTV, and SbCNV-5] were detected within SCN greenhouse and field populations from North Carolina (NC) and Missouri (MO). The prevalence and titers of viruses in SCN from 43 greenhouse cultures and 25 field populations were analyzed using qRT-PCR. Viral titers within SCN greenhouse cultures were similar throughout juvenile development, and the presence of viral anti-genomic RNAs within egg, second-stage juvenile (J2), and pooled J3 and J4 stages suggests active viral replication within the nematode. Viruses were found at similar or lower levels within field populations of SCN compared with greenhouse cultures of North Carolina populations. Five greenhouse cultures harbored all five known viruses whereas in most populations a mixture of fewer viruses was detected. In contrast, three greenhouse cultures of similar descent to one another did not possess any detectable viruses and primarily differed in location of the cultures (NC versus MO). Several of these SCN viruses were also detected in Heterodera trifolii (clover cyst) and Heterodera schachtii (beet cyst), but not the other cyst, root-knot, or reniform nematode species tested. Viruses were not detected within soybean host plant tissue. If nematode infection with viruses is truly more common than first considered, the potential influence on nematode biology, pathogenicity, ecology, and control warrants continued investigation.

    The potential for recovery of left ventricular dysfunction after myocardial revascularization represents a practical clinical definition for myocardial viability. The evaluation of viable myocardium in patients with severe global left ventricular dysfunction due to coronary artery disease and with regional dysfunction after acute myocardial infarction is an important issue whether left ventricular dysfunction may be reversible or irreversible after therapy. If the dysfunction is due to stunning or hibernation, functional improvement is observed. But stunned myocardium may recover of dysfunction with no revascularization. Hibernation is chronic process due to chronic reduction in the resting myocardial blood flow. There are two types of myocardial hibernation; 'functional hibernation' with preserved contractile reserve and 'structural hibernation' without contractile reserve in segments with preserved glucose metabolism. This review focus on the application of F-18 FDG and other radionuclides to evaluate myocardial viability. In addition the factors influencing predictive value of FDG imaging for evaluating viability and the different criteria for viability are also reviewed

    Full Text Available Hemifacial Spasm (HS occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom.

    Full Text Available The lateral periodontal cyst is an uncommon, but well-recognized type of developmental odontogenic cyst. Lateral periodontal cysts are defined as non-keratinized and non-inflammatory developmental cysts located adjacent or lateral to the root of a vital tooth. It is a relatively uncommon lesion found mostly in adults (5th to 7th decades and it is rare in young people under 30 years of age. A common site of occurrence is the mandibular premolar region. It does not have a predilection for any race or sex. Histopathologically, the lateral periodontal cyst lining is characterized by a thin cuboidal to stratified squamous non-keratinizing epithelium, ranging from one to five cell layers and presence of one or more epithelial thickenings or plaques.The purpose of this article is to report a case of interradicular radiolucent cystic lesion in a thirteen-year-old girl, located in a rare site of the maxillary premolar area, mimicking clinical and radiographical features of a residual cyst, but histopathologically proven to be a lateral periodontal cyst.

    A pineal cyst is a benign affection of a pineal gland on the borderline between a pathological lesion and a variant of normality. Clinical management of patients with a pineal cyst remains controversial, especially when patients present with non-specific symptoms. An online questionnaire consisting of 13 questions was completed by 110 neurosurgeons worldwide. Responses were entered into a database and subsequently analysed. Based on data from the questionnaire, the main indication criteria for pineal cyst resection are hydrocephalus (90 % of the respondents), Parinaud's syndrome (80 %) and growth of the cyst (68 %). Only 15 % of the respondents occasionally operate on patients with non-specific symptoms. If surgery is indicated, improvement is expected in 88 % of the patients. The vast majority of the respondents favour a supracerebellar infratentorial approach to the pineal region. Most (78 %) of the respondents regarded the patient registry as a potentially useful instrument. This survey sheds light on the current practice of pineal cyst management across the world. Most of the respondents perform surgery on pineal cysts only if patients are presenting with symptoms attributable to a mass effect. Surgery for patients with non-specific complaints (headache, vertigo) is not widely accepted, although it may prove effective. A prospective patient registry might be useful in the decision-making process in the clinical management of pineal cysts.

  9. Epidermoid/Dermoid cysts mimicking odontogenic infections: review of literature

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Introduction: Dermoid/Epidermoid cysts are rare pathologic lesions that may involve the floor of the mouth. Infection and inflammation of the cyst can produce a clinical picture very similar to the submandibular and submental abscesses with odontogenic origin. Dermoid/epidermoid cysts are on the floor of the mouth with submental or submandibular component can be mistaken for odontogenic infections. Methods: Four biopsy proven dermoid/epidermoid cysts operated in the Mashhad University of Medical Sciences, Ghaem hospital (2012-2013, were reviewed. Results: Four patients, including two classic cases and two infected dermoid/epidermoid cysts, were erroneously diagnosed as odontogenic infection. Discussion: The lesions located solely below mylohyoid muscle need to be removed through anextraoral approach but the lesions above the mylohyoid muscle or those that have both supra- and infra-mylohyoid components can be removed through an intraoral incision.Conclusion: Dermoid/epidermoid cysts should be considered in the differential diagnosis of submental/submandibular swellings. In the absence of an odontogenic cause of infection, fine-needle aspiration biopsy and appropriate imaging evaluation techniques with sonography, CT or MRI are mandatory for correct diagnosis and surgical treatment planning. The clinicians should be very cautious to differentiate odontogenic infections from infected dermoid/epidermoid cysts.

    The purpose of this research was to retrospectively characterize paralabral cysts of the hip as seen at MR arthrography. After Institutional Review Board approval, 704 patients who had MR arthrography were identified over a 3-year period and 40 patients were identified as having a cyst or fluid collection at the hip by MR report. MR images from these 40 patients were retrospectively reviewed by three radiologists where 18 were found to have a paralabral cyst, which were characterized as follows: location, configuration, contrast filling, size of the cyst, extent, direction, and whether associated osseous changes were present. In addition, the acetabular labrum was assessed for tears and, if present, the location and pattern were characterized. Paralabral cysts were located anterosuperiorly in 56%, anteriorly in 22%, posterosuperiorly in 17%, and anteroinferiorly in 6% of cases. The vast majority (94%) were multilocular and filled with intra-articular contrast medium. The average dimensions were 8 x 7 x 11 mm. The paralabral cyst demonstrated extracapsular extension in 72% of cases, with 39% located between the ilium and gluteus minimus, and 22% between the ilium and iliopsoas. Remodeling of the ilium adjacent to the cyst was observed in 50% of these cases. A labral tear was at the base of the labrum adjacent to the cyst in 78% of cases, while the tear was isolated to the body of the labrum in 22%. Tears were most commonly anterosuperior (55%) or anterior (28%) in location. Our results show that paralabral cysts of the hip are most commonly located anterosuperiorly, are multilocular, fill with intra-articular contrast medium, have average dimensions up to 11 mm, and often extend extracapsularly between muscle and bone where they may remodel the adjacent ilium.

    1980-09-01

    The clinical and pathologic features of 25 cases of phaeomycotic cyst, collected at the Armed Forces Institute of Pathology between 1959 and 1978, are described. Phaeomycotic cyst is infection of the deep dermis and subcutaneous tissue by dematiaceous (brown) fungi. Species of Phialophora were most frequently isolated from these lesions. Synonyms for phaeomycotic cyst are--among others--phaeomycosis and phaeosporotrichosis. Phaeohyphomycosis includes phaeomycotic cyst and some other mycoses. The term "phaeo" is derived from the Greek phi alpha iota omicron sigma, meaning grey or black, and refers to the brown color in vivo and in vitro of these fungi. Phialophora species are world-wide saprophytes, common in soil, decaying wood, and vegetation. They have low virulence and low pathogenicity, and are inoculated along with slivers whose retention is probably an important causal factor in establishing infection. Proliferation of the fungi provokes a mixed suppurative and granulomatous reaction which remains localized. Early the characteristic histopathologic picture is one of multiple stellate abscesses. These progress to a single circumscribed lesion with a central cavity filled with pus and surrounded by a fibrous wall. There are no systemic signs or symptoms, regional lymph nodes are not involved, nor has any patient had systemic spread. The infection is rare but tends to be more common in warm climates. No race, sex, or age group is predisposed, but patients with immune deficiency or debilitating disease are at increased risk. In older publications phaeomycotic cysts have been described as variants of chromomycosis, sporotrichosis, and mycetoma. Phaeomycotic cysts, however, do not provoke hyperplasia of the epidermis or ulceration--characteristic features of both chromomycosis and sporotrichosis, nor do phaeomycotic cysts form sinus tracts or contain grains--both typical features of mycetoma. The strictly localized abscess or "cyst" is the characteristic feature of

    Full Text Available Meniscal cysts are a relatively uncommon occurrence that may result in pain and disability in the knee. It is widely believed that meniscal cysts are secondary to fluid extrusion from a meniscus tear. Typically, diagnosis of a meniscal cyst typically requires magnetic resonance imaging (MRI to delineate the cyst and any associated injuries. With improvements in sonographic technology, ultrasound has emerged as a sensitive modality for detection of meniscal cysts. We present a patient with a contraindication to MRI who was diagnosed with a lateral meniscal cyst by musculoskeletal ultrasound and treated with an ultrasound-guided lateral meniscal cyst aspiration and injection.

    Full Text Available Intracranial neurenteric cysts are exceedingly rare congenital intracranial lesions that result from disorder of gastrulation. Still, more rarely, the cyst contents may leak into the CSF and give rise to recurrent episodes of chemical meningitis. We present a case of chemical meningitis due to a leaking posterior fossa neurenteric cyst in a young female, with emphasis on its imaging features. The final diagnosis was achieved by sufficiently characteristic imaging features; histopathologic documentation could not be achieved as the patient denied surgery.

Excisional biopsy of the mass was performed and histopathological findings were consistent with those of trichilemmal cyst. We report a rare case of trichilemmal cyst of the eyelid which was masquerading as chalazion for which the patient had undergone multiple surgeries. Wide excision was done and diagnosis was confirmed on histopathology. There was no recurrence seen till 2 months of postoperative period. Trichilemmal cyst, although rare, should be considered as differential diagnosis of recurrent chalazion.

    Incomplete urethral duplication with cyst formation was diagnosed in a dog that had soft, fluctuant, subcutaneous swellings in the ventral perineal and penile areas and a history of nocturia and incontinence during recumbency that were unresponsive to treatment with antibiotics. Retrograde urethrocystography, voiding urethrography, double-contrast cystography, radiography after direct administration of contrast medium into cystic structures, and excretory urography were performed to evaluate the urinary tract. Communication between the cysts and the urethra was demonstrated radiographically only after intralesional injection of contrast medium. Nocturia and incontinence resolved after surgical removal of the urethral duplication and cysts. The dog was clinically normal 1 year after surgery

    Full Text Available Trauma to the deciduous teeth may have severe consequences. Pulp necrosis is the commonly observed sequel in traumatized primary teeth and is one of the possible etiologic factors for the development of dentigerous cyst. Dentigerous cyst is more commonly seen in mandibular third molar and maxillary canine region and is rarely associated with other teeth. This article addresses a case of dentigerous cyst associated with the germ of upper permanent central incisor, an uncommon site of occurrence, which was impacted, dislodged from its natural site of eruption after trauma to the predecessor incisor.

    Full Text Available Odontomas are considered to be hamartomatous malformations rather than true neoplasms. This most common odontogenic lesion results from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblasts and odontoblasts. Dentigerous cyst is an epithelium-lined sac enclosing the crown of an unerupted tooth. Apparently, the dentigerous cyst arises by the accumulation of fluid between reduced enamel epithelium and the tooth crown. Occasionally it is associated with supernumerary tooth or odontoma. We report a case of dentigerous cyst associated with complex composite odontoma and an impacted lateral incisor in a 30-year-old male patient.

    Full Text Available The calcifying odontogenic cyst (COC is a rare odontogenic cyst. Only 2% of all odontogenic cysts and tumors are COC. COC associated with odontoma (COCaO reported in 24% of COCs. COCaO presents a greater incidence in female, with a ratio of 2 to 1. The highest incidence of COCaO occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%. Here, we describe a classic case of COCaO of the maxillary incisor-canine region in 17-year-old girl, and discuss the clinicopathological features and immunohistochemical finding of this tumor.

    Odontomas and dentigerous cysts are common findings for practicing dental professionals. However, simultaneous occurrence of pathologies like odontoma and dentigerous cyst are uncommon and their diagnosis based on the radiographic appearance alone is a challenge to overcome. They together are a potential for complications like attaining large size, root resorption, destruction of the jaw bones and sometimes neoplastic changes like ameloblastoma. This paper presents a case of complex odontoma associated with dentigerous cyst in relation to a retained deciduous tooth in the maxillary anterior region and confirming its diagnosis histopathologically.
