Retroperitoneal lymphatic malformation and transverse testicular ectopia: A unique clinical presentation


      This case report presents a fetal patient diagnosed in utero with a retroperitoneal lymphatic malformation by ultrasound and followed through gestation. At birth the child was noted to have a right inguinal hernia with two palpable testicles. Plan for partial resection and hernia repair with postoperative sclerotherapy was made. At the time of hernia repair, transverse testicular ectopia was diagnosed, and subsequent extraperitoneal transposition orchiopexy was performed following partial resection of the lymphatic malformation. Delayed sclerotherapy in combination with partial resection afforded definitive treatment of the residual lymphatic malformation as the patient demonstrates no recurrence over one year later. This is the first reported case to suggest a direct relationship between transverse testicular ectopia and a retroperitoneal lymphatic malformation.
