RATIONALE: Bronchogenic cyst (BC) is a congenital disease characterized by an anomaly of the foregut in the embryonic stage. Gastric BC is exceedingly rare and has never been accurately diagnosed prior to surgery; it is often misidentified as gastric stromal tumor, with the definitive diagnosis confirmed through postoperative specimens. Although gastric BC is considered a benign lesion, its prognosis remains uncertain, underscoring the importance of accurate preoperative identification. PATIENT CONCERNS: The present study reported the case of a 64-year-old female who presented with 2 incidentally detected lesions of the gastric corpus and antrum. Computed tomography and magnetic resonance imaging showed cystic lesions with delayed enhancement of the cyst wall and no enhancement of the cyst contents. INTERVENTIONS AND DIAGNOSES: The patient underwent a laparoscopic partial gastrectomy. BC was diagnosed by histopathology and immunohistochemistry after surgery. OUTCOMES: The patient had an uneventful hospital course and was discharged on the eleventh postoperative day. No recurrence or metastasis was observed after 33 months. LESSONS: BC of the stomach is mostly ovate in shape with well-defined margins. The cyst wall shows prolonged enhancement and calcification may occur at the edges. The density and signal of the cyst content varied with composition. These imaging features are helpful for differentiating diagnoses from other diseases.
