A Prenatally Detected Paratesticular Cyst Associated With Intra-abdominal Testis

Abstract

We report on a neonate with a paratesticular cyst associated with intra-abdominal testis. A large abdominal cyst was detected by prenatal ultrasonography at 34 weeks of gestation. Preoperative diagnostic imaging demonstrated a cystic lesion 6×4×3 cm in size in the left suprapubic area. Left testis was nonpalpable in the inguino-scrotal region. He underwent operation at the age of 21 days. At operation, a large cyst accompanied by left spermatic vessels and vas deference was confirmed laparoscopically. Laparoscopic-assisted orchiectomy was performed. Histopathological diagnosis was a mesothelial cyst arising from paratesticular tissue. His postoperative course was uneventful.
