Prolapsing inflammatory pseudopolyp-fold complex of the oesophagogastric region

This article describes a series of 12 adult patients in whom a prominent and mobile polypoid fold of the oesophagogastric region was demonstrated radiologically. Subsequent endoscopic and histopathologic studies confirmed the presence of an inflammatory pseudopolyp at the squamocolumnar junction and contiguous with a thick gastric rugal fold. The clinical and radiographic features of this entity and the mechanisms of its formation are reviewed. (orig.)
