超音波内視鏡が診断上有用であった胃隆起性病変の一例

Abstract

A 70-year-old female visited a nearby physician with a complaint of discomfort in the upper abdomen that had lingered for two weeks. X-ray examination revealed the possibility of a gastric tumor. She was referred to the O. P. D. of this hospital in April, 1987. The endoscopic examination showed a beaded elevated lesion with smooth surface on the posterior wall of the upper corpus of the stomach. This finding suggested either varices or submucosal tumor, but a definite diagnosis was not entablished. In November, 1987, endoscopic ultrasonography was carried out and the diagnosis of gastric varices was established. This type of gastric varices is rarely found in that position. No other varices were found in the esophagus or cardiac region of the stomach. Despite carrying out various examinations, we failed to clarify the cause of this lesion. This lesion was probably due to some kind of vascular malformation. We should recognize the usefulness of endoscopic ultrasonography for differential diagnosis of gastric elevated mass as in such a case as this.
