Cystic Lesions of the Gastrointestinal Tract: Multimodality Imaging with Pathologic Correlations

Abstract

The cystic lesions of the gastrointestinal (GI) tract demonstrate the various pathologic findings. Some lesions may present a diagnostic challenge because of non-specific imaging features; however, other lesions are easily diagnosed using characteristic radiologic features and anatomic locations. Cystic masses from the GI tract can be divided into several categories: congenital lesions, neoplastic lesions (cystic neoplasms, cystic degeneration of solid neoplasms), and other miscellaneous lesions. In this pictorial review, we describe the pathologic findings of various cystic lesions of the GI tract as well as the radiologic features of GI cystic lesions from several imaging modalities including a barium study, transabdominal ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging.

Imaging, endoscopy, and pathologic findings of primary gastritis cystica polyposa: description of a rare entity in a small case series

“…The solid portion was relatively obvious (mucosal polypoid hyperplasia) and was often accompanied by fine pointlike cystic changes internally [4][5][6][7][8][9][10]12]. However, this cohort only had one case similar to the reports in the literature, whereas the remaining cases were primarily dominated by the cystic component, with thick mucosal hyperplasia on the surface.…”

AIRP Best Cases in Radiologic-Pathologic Correlation: Gastritis Cystica Polyposa

“…A definite diagnosis is difficult to establish radiologically, since imaging features are often nonspecific. Cystic gastrointestinal masses can be broadly divided into congenital lesions, neoplastic lesions (including both cystic lesions and cystic degeneration of solid tumors), and other rare lesions such as GCP and Brunner gland hyperplasia (21). Submucosal gastric lesions include heterotopic pancreas (typically along the antrum), duplication cyst (uncommon), GIST, and schwannoma (18,21,22).…”

Gastritis Cystica Polyposa in the Unoperated Stomach: A Case Report

“…Gastritis cystica polyposa (GCP) is a rare condition, which is histologically characterized by polypoid hyperplasia of the gastric mucosa with cystic dilation of glandular structures (1).…”

“…Chronic mucosal irritation, by bile reflux and increased mucosal mobility in the operated stomach, are thought to play important roles in the pathogenesis of GCP (3). Nevertheless, GCP is rarely found in patients without any prior history of gastric surgery (1,4,5).…”

“…In these cases, GCP is thought to be related to chronic gastritis or ischemia (1). To the best of our knowledge, there are only a few reports of GCP arising from the unoperated stomachs.…”
