title: Gastric bronchogenic cyst diagnosed by endosonographically guided fine needle aspiration biopsy.
abstract: We report a case of a gastric bronchogenic cyst diagnosed via endosonographically guided fine-needle aspiration (EUS-FNA) biopsy. A 60-year-old woman was referred to our hospital for an endoscopic ultrasound (EUS) examination because of a gastric subepithelial lesion detected by upper gastrointestinal endoscopy. EUS examination revealed a lesion that appeared to originate from the gastric submucosa but seemed to extend beyond the gastric wall. The latter finding raised concerns that the lesion might represent a cystic neoplasm rather than a simple cyst. Subsequently, EUS-FNA was performed to establish a definitive diagnosis and to guide further management. Cytologic evaluation of aspirated material revealed the presence of benign-appearing ciliated columnar epithelial cells within a mucinous background. Based on imaging and EUS-FNA findings, a diagnosis of gastric bronchogenic cyst was made and surgical resection was avoided.
