An abdominal bronchogenic cyst

An 18-year-old woman presented with aggravated vomiting for 10 months, without remarkable past history. Both her physical examination and laboratory were normal. Upper endoscopy showed a soft spherical bulge with smooth surface in the gastric cardia and fundus (Fig. 1a). Endoscopic ultrasound demonstrated that the lesion was an extrinsic compression. Enhanced computed tomography scan was performed, revealing a low dense cystic lesion with wall enhancement (Fig. 1b, arrows). The lesion was found to be located in the abdomen, and was completely excised by laparoscopic surgery. Histologic findings reported the presence of ciliated pseudostratified columnar epithelium in the cyst wall (Fig. 1c, H&E 400×), thus an abdominal bronchogenic cyst was finally diagnosed. The patient was discharged without any complications. Her symptom was gone during follow-up.

Bronchogenic cysts below the diaphragm are extremely rare.¹ Although most of them are benign and asymptomatic, symptoms can be developed owing to compression of adjacent organs, cyst rupture or secondary infection. Malignancy changes can be also noted.² As retained cyst wall will cause a recurrence, complete excision of the cyst is of vital importance.
