title: Cystic intra-abdominal testicular torsion in an infant.
abstract: We report on a 3-month-old infant with cystic intra-abdominal testicular torsion. He presented with abdominal distension and pain. Physical examination showed a movable, well delineated mass in the right iliac and lumbar fossae. Exploration revealed that the mass was connected to the abdominal aorta by a thin vascular cord that was twisted before reaching the mass. The histological study showed that the mass corresponded to a testis with cystic formations. The testicular parenchyma was necrotized, although isolated seminiferous tubules were found. The cystic cavities were filled by hematic and necrotic material, and exhibited no epithelial lining. A fibrous layer in continuity with interstitial hemorrhage surrounded the cysts. The twisted vascular cord corresponded to a spermatic cord with dilated pampiniform plexus veins. The differential diagnosis and the etiopathogenesis of the lesion are discussed.
