Transdiaphragmatic jejunal duplication: a report of five cases

Five infants with intrathoracic transdiaphragmatic duplication cysts are presented. Diagnosis was possible from the combination of several features on plain chest radiographs: (a) right-sided cystic areas lying posteriorly in the chest, (b) lower cervical or upper dorsal spinal dysraphism, and (c) unusual gas collection beneath the right hemidiaphragm. Barium studies, positive-contrast myelography, and computed tomography were helpful in preoperative assessment.
