Preoperative diagnosis of pancreatic body and tail cyst: a case of gastric bronchogenic cyst and literature review.

Bronchogenic cyst is a condition arising from congenital abnormalities in the respiratory system. It can be classified into intrapulmonary, mediastinal, and ectopic types depending on its location. Ectopic types are rare, and diagnosis typically depends on pathological examination. This paper presents a case of a female patient admitted to our hospital with abdominal pain. Preoperative imaging revealed a mass in the tail of the pancreas, which was surgically excised. Postoperative pathology confirmed the diagnosis of a gastric bronchogenic cyst. Based on the patient's diagnosis and treatment, it is recommended that the diagnosis of gastric bronchogenic cysts be supported by auxiliary examinations, such as imaging, with final confirmation achieved through postoperative histopathology, as suggested by a review of the relevant literature. Surgical treatment is the preferred approach for gastric bronchogenic cysts.
