RESUMO
Bronchogenic cysts are congenital foregut dysplasia that occur mostly in the lungs and mediastinum. Here, we report a rare case of retroperitoneal bronchogenic cyst, the location, relationship to adjacent structures and blood supply of which were determined by computed tomography (CT) recombination technology and resected by laparoscope. The case was a 41-year-old female patient. The patient came to the hospital because of intermittent lumbar back discomfort for 1 month. CT scanning revealed a cystic mass of 3.9 cm × 3.2 cm × 3.0 cm behind the left peritoneum. The mass was close to the left adrenal gland, and a branch artery from the left renal artery was revealed to supply the mass. The cystic mass was excised by laparoscopy and confirmed as bronchogenic cyst on histopathology.
