Abstract
Abdominal bronchogenic cysts are very rare with less than 20 published cases. We report the case of a retroperitoneal bronchogenic cyst in a 12-year-old boy, who initially presented with a primitive neuroectodermal tumor of the pelvis. Computed tomography (CT) showed a small, hyperdense nonenhancing mass adjacent to the right crus of the diaphragm. Follow-up CT after chemotherapy showed a decrease in CT attenuation of this mass, but a slight increase in size. At surgery the mass was loosely attached to the diaphragm and final pathology confirmed the diagnosis of a bronchogenic cyst.
