Introduction
Bronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection.
Case presentation
A 40-year-old North African man was admitted to our hospital with a gastric submucosal mass. An endoscopic ultrasound revealed a unilocular cystic mass located in the muscular layer. Its content was echogenic suggestive of mucus. Magnetic resonance imaging confirmed the liquid nature of the cyst and showed a high ratio of proteins. Based on these observations, the diagnosis of bronchogenic cyst was confirmed. An endoscopic monitoring was decided rather than surgery because of the small size of the cyst and the absence of symptoms.
Conclusion
Although gastric bronchogenic cysts are rare, they should be well known and considered in all differential diagnoses of gastric tumors. We report a new case of gastric bronchogenic cyst and highlight the contribution of morphological tests that currently allow a non-invasive diagnosis.
