a 14 years old boy who had a ventriculo-peritoneal shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. in abdominal ct and sonographic evaluation, pancreatic pseudocyst or mesentric cyst were suspected. evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudocyst at the peritoneal end of the shunt. the pati...

BACKGROUND/AIMS Management of pancreatic pseudocysts can be challenging. Endosonography-guided drainage of the pseudocysts is an important treatment modality. In this study, we evaluated the results of endosonography-guided transmural endoscopic drainage of these lesions. MATERIALS AND METHODS We performed drainage of the pancreatic pseudocysts through the stomach or duodenum using a linear e...

Pancreatic cystic lesions are usually inflammatory pseudocysts (90%) or, infrequently, neoplastic processes [1]. A lymphoepithelial cyst (LEC) of the pancreas is a rare true cyst of this organ and is lined by squamous epithelial tissue surrounded by lymphoid tissue with germinal centers [2]. This rarely seen lesion should be considered in the differential diagnosis of cystic neoplasms of the pa...

Retroperitoneal bronchogenic cyst is detected extremely rarely and often masquerades as other diseases. Here, we report 2 cases of retroperitoneal bronchogenic cyst mimicking pancreatic mucinous tumor. Histologically, both cysts were composed of ciliated respiratory-like epithelium with abundant mucin content, smooth muscle bundles and mature cartilage, compatible with the diagnosis of retroper...

INTRODUCTION Primary pancreatic hydatid cyst is extremely rare and may be a causative factor for obstructive jaundice. CASE PRESENTATION A 27-year-old woman presented with obstructive jaundice, vomiting, pruritus, abdominal pain and an epigastric mass. A diagnosis of a pancreatic cyst causing a compression of the common bile buct was established by ultrasonography and CT scan before surgery. ...

The gastrointestinal duplication of stomach is uncommon congenital anomalies of gastrointestinal tract. Herein a rare case of gastric duplication with newborn is being reported. A 14-day-old term female baby was admitted to our clinic with intermittent bilious vomiting and abdominal distention. In evaluation, abdominal cystic mass was detected in the left upper quadrant. The cyst which was atta...

Histopathological study of the endoscopically resected specimen revealed the presence of a unilocular cystic lesion under the rectal mucosa (Figure 1A). Smooth muscle bundles were recognized around the entire cyst (Figure 1A), and no connection with surface rectal mucosa was noted. The cyst wall was covered by pseudostratified ciliated epithelium (Figure 1B), and accumulation of neutrophils was...

Choledochal cyst is the congenital abnormality that almost invariably requires surgical intervention to prevent hepaticobiliary & pancreatic complications. Although majority of these patients present in infancy & childhood, about 20 – 30% are diagnosed in adults. This study was both retrospective & prospective in 30 patients from Jan, 2011 to Feb. 2014 admitted in the Department of General Surg...

Diagnosing Pancreatic Cysts Doctors use computed tomography (CT) or magnetic resonance imaging(MRI)scanstodiagnosepancreaticcystsanddeterminetheir type. These tests can also identify features of the cysts that suggest an increased risk of cancer. If imaging scans cannot identify the typeof cyst or if the cyst has aconcerningappearance,doctorsmayalsouseanendoscopicultrasound procedure. This invo...

S6 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 50–85 months) of the 114 patients with CR, only two patients (1.7%) showed cyst recurrence. Based on multivariate analysis, the absence of septa (odds ratio [OR], 7.12; 95% confidence interval [CI], 2.72–18.67) and cyst size <35 mm (OR, 2.39; 95% CI, 1.11–5.16) predicted CR. Conclusion: Among patients with pancreatic cysts who ach...
