Endoscopic Ultrasonographic Features of a Gastric Aberrant Pancreas without Central Dimpling / 대한소화기내시경학회지

BACKGROUND/AIMS: A gastric aberrant pancreas can be easily diagnosed through con- ventional endoscopy and radiologic modalities due to its characteristic features such as central dimpling. However, in cases involving an aberrant pancreas without the central dimpling, the differential diagnosis has been some troublesome. As for differential diag- nosis of gastric submucosal tumors, endoscopic ultrasonography (EUS) allows us to visu- alize the structures underlying the gastrointestinal wall in a non-invasive manner, and has a great advantage over conventional modalities such as conventional endoscopy or the UGI series. METHODS: We studied the EUS findings of a gastric aberrant pancreas without the central dimpling. We compared EUS features in 10 cases involving a gastric aberrant pancreas without the central dimpling to those in 16 cases with the central dimpling.

Esophagus, Stomach & Intestine; A Case of Adenomyoma of Duodenum / 대한소화기내시경학회지

Adenomyoma of the gastrointestinal tract has been considered to be a form of pancreatic heterotopia. Heterotopic pancreatic tissue in the gastrointestinal tract is a relatively not uncommon abnormality, but adenomyoma is a rarely reported tumor and its ineidence is difficult to determine. Adenomyoma is similar to aberrant pancreas in both appearance and location, and cannot be differentiated endoscopically or radiographically. Histologically, adenomyoma is primarily composed of smooth muscle and undifferentiated duct like structures. It is usually of no clinical importance and incidentally detected, but according to its location and size of the mass, it may become a serious clinical problem. Its real importance lies in the recognition of its existence, to facilitate a timely diagnosis, We present a case of adenomyoma of the duodenum with a brief literature review.
