Schwannomas are derived from Schwann cells, the most common sites being upper extremiteis, trunk, retroperitoneum, head and neck, mediastinum. However they can arise from the gastrointestinal tract too, including the biliary system. We present a case of a 40 year old gentleman, who presented with obstructive jaundice whose computed tomography of the abdomen was suggestive of mass lesion at the ...

While previous studies did indeed advance novel treatment methods for NSCLC, the team in Bangkok Hospital found it curious that even in a recent study published in April 2012, the most advanced staging evaluation methods used were mediastinoscopy or mediastinotomy (following bronchoscopy, bone scan, computed tomography (CT) scan of the chest) to acquire biopsy samples from lymph nodes. A random...

A 34-year-old male was referred to our hospital for drainage of symptomatic pancreatic fluid collections (PFCs) secondary to an acute pancreatitis. He was affected by gastro-duodenal and biliary obstruction. CT scan images revealed 1 perigastric pseudocyst (well-defined wall, without necrosis content, 70 x 120 mm) and 1 periduodenal walled-off pancreatic necrosis (WOPN) (thickened wall, partial...

We report the case of a 35-year-old female patient with a metastasized carcinoid of the papilla of Vater which is a rare lesion. 96 cases have been published in world literature previously. The carcinoid of the papilla of Vater appears typically as a hormone inactive tumor. It becomes symptomatic by cholestasis and jaundice in most cases and not by carcinoid-syndrome. An association with von Re...

A 50-year-old man was admitted to our department, complaining of epigastric pain and high fever. CT revealed a pseudocyst at the pancreatic head with upstream dilatation of the pancreatic duct (PD) and fluid collection surrounding the pancreas. Endosonography-guided PD drainage (ESPD) was performed because of unsuccessful ERCP. With a curved linear array echoendoscope, a 7.2 F catheter was plac...

Endoscopic ultrasound (EUS) is considered a valuable diagnostic tool during the workup of malignant gastric lesions, including primary gastric lymphomas (PGL). Although endoscopy combined with multiple biopsies remains essential in the establishment of PGL diagnosis, EUS utilization in locoregional disease staging has been well documented in the literature. Data also support the possible role o...
