A Case of Pseudolipomatosis in the Gastric Mucosa / 대한소화기내시경학회지

ABSTRACT

Mucosal pseudolipomatosis is a recently described endoscopic finding consisting of benign transient lesions. This condition, resembling fatty infiltration, is characterized by the presence of small gas voids in the gastrointestinal wall, particularly in the mucosa. The frequency of colonic pseudolipomatosis is higher than the frequency of pseudolipomatosis of the stomach. Both mechanical and chemical theories have been offered to explain the pathogenesis of colonic pseudolipomatosis. The mechanical theory pertains to an air pressure-related complication of the colonoscopy procedure. The chemical theory concerns a drug-related complication of the detergent used during colonoscopies. However, the pathogenesis of gastric pseudolipomatosis is still unclear. Recently, we had a patient who experienced gastric pseudolipomatosis after endoscopoy and biopsy procedures. In the following report we discuss this interesting case of gastric pseudolipomatosis.
