Intramuscular Bronchogenic Cyst of Gastric Body: A Case Report

Developmental foregut cysts, whether bronchogenic, esophageal, gastroenteric or pericardial, are frequently encountered in the mediastinum, and are also occasionally found in the upper abdomen, where they can mimic adrenal, pancreatic, renal or gastric masses. We present the computed tomographic (CT) and histologic findings of an intramuscular bronchogenic cyst of the gastric body, mimicking a retroperitoneal cystic mass. CT scanning demonstrated the presence of a relatively hyperattenuating cystic mass without enhancement. Histologic examination revealed a bronchogenic cyst secreting mucoid materials.

Cystic Lesions in the Stomach

Cystic lesions of the stomach are rare and usually detected incidentally during surgery or autopsy. Amongseven cases of cystic masses, duplication cysts accounted for four, retension cysts of ectopic pancreas for two,and cystic lymphangioma remaining one. In the upper gastrointestinal series, all were submucosally, whileendoscopic ultrasonography showed that the location of cystic masses was also submucosal. Except for two cases ofduplication cyst and cystic lymphangioma which were thin-walled, lesions were well-defined and showed lowattenuation. In addition, abdominal CT scanning showed two cases of retension cyst of ectopic pancreas.
