title: Challenge in preoperative diagnosis of retroperitoneal mucinous cyst in a pediatric patient.
abstract: Mucinous cystic lesions of the retroperitoneum can be either neoplastic or non-neoplastic. It is very important to make a correct diagnosis, or at least, an accurate classification, to proceed with an optimal treatment strategy. In spite of advantage of ultrasound and X-ray image examinations, it is still a challenge to make differential diagnosis of retroperitoneal mucinous cyst from gangliocytoma because both tumors have similar density under the image assessment. In this article, we reported an asymptomatic 8-year-old boy with multiple bronchogenic cysts in both lung and adrenal area on the left side, the latter was considered to be a gangliocytoma preoperatively by ultrasound and computed tomography, but confirmed as bronchogenic cyst by histopathology post laparoscopic resection. The differential diagnosis, imaging features and treatment of bronchogenic cyst are discussed and the relative literatures are reviewed.
