Alpha-fetoprotein (AFP) is a common tumor marker for hepatocellular carcinoma (HCC). We report a unique case of an AFP-producing gastric cancer in an elderly man with known chronic hepatitis B (HBV) and a markedly elevated AFP. Thorough diagnostic imaging failed to reveal a HCC, but a gastric adenocarcinoma was found on endoscopy. After successful resection, the serum AFP normalized. On histopa...

We present a case of a 55-year-old woman with pontine infarction and fenestration of the basilar artery that was demonstrated using virtual endoscopy. The patient had motor weakness of the right side with sudden onset. Diffusion- and T2-weighted MR images revealed high signal intensities in the left pontine regions, and an MR angiographic examination showed the double-lumen sign of the basilar ...

introduction rhinoliths are uncommon nasal masses. they are mineralized masses found within the nasal cavity. they have various clinical presentations. case presentation we report a 13-year-old boy with long-standing nasal obstruction, yellowish nasal discharge and intermittent and minimal nasal bleeding for a few weeks, who had been treated as rhinosinusitis twice. due to the presence of long-...

Obscure gastrointestinal bleeding is a common disorder and may account for as many as 5% of all gastrointestinal hemorrhages. It is often caused by lesions in the small intestine, which were very complicated to examine prior to the advent of wireless capsule endoscopy. Here we present the case of a 31-year-old woman with obscure gastrointestinal bleeding as a complication of radiation enteritis...

Narrow band imaging (NBI), in conjunction with magnifying endoscopy (ME), has arisen more and more attention in the area of advanced endoscopy. By enhancing the mucosal microvascular architecture and surface pattern, it is feasible to use ME-NBI to identify subtle changes associated with gastric inflammation, atrophy, intestinal metaplasia, and early gastric cancer. The new technique thus plays...

A 28-year-old man diagnosed with Charge syndrome and no history of NSAIDs ingestion was referred due to the presentation in the previous 24 h of melenic stools with a negative upper endoscopy. Physical examination was unremarkable, although laboratory tests showed anemia. On the second day, significant painless rectal bleeding and the decrease of hematocrit levels responding to blood transfusio...

The diagnosis of neuroendocrine malignant tumor in the small bowel is difficult [J Oncol 2008;2008:212067]. It is usually found intraoperatively during intestinal resection and confirmed by subsequent histological examination. We reported a case of jejunum neoplasm which was misdiagnosed as Crohn's disease by capsule endoscopy. Capsule endoscopy was stuck in the jejunum stricture and was remove...

A 60-year-old male presented with renal failure and right coronary myocardial infarction. Transesophageal echocardiography showed many tumors (Fig. 1). Endoscopy showed multiple ectopic calcifications in a line on the mitral annulus (Fig. 2). Ectopic calcifications were removed and mitral valve annu-plasty was performed. Histopathologic examination confirmed these were dense calcifications. Fig...

Here, we present a case of a 78-year-old man that underwent gastrointestinal endoscopy because of one- month history of dysphagia to liquids and solid foods with accompanying weight loss. On endoscopy, there was distal esophageal stenosis. Multiple biopsies were obtained. Histologic examination of the samples revealed normal tissue. The stenosis was treated by dilatation and abdomino pelvic com...

Radiation enteritis is a complex clinical entity secondary to the affectation of intestinal epithelial cells as a result of radiation in the management of pelvic malignancies that may occasionally cause intestinal strictures. We present the case of a 60 year-old woman who had been diagnosed ten years before with endometrial adenocarcinoma, and who underwent hysterectomy with double adnexectomy ...
