A case of lymphatic malformation/lymphangioma of the scrotum
A 12-year-old boy presented to our hospital with a swollen right scrotum without tenderness. He had a surgical history of bilateral inguinal hernia, uncal hernia, and scrotal hydrocele at 2 years old. Ultrasonographic examination revealed a well-defined multicystic mass in the right scrotum. Color Doppler examination showed no blood flow in the septum of the cysts (Fig. ). Bilateral testes were normal. Magnetic resonance imaging revealed a multicystic mass (6.5 × 6.5 × 9.0 cm) with multiple thin septae and locules located in the right scrotal sac. The mass showed high intensity on T2-weighted imaging and low intensity on T1-weighted imaging. On diffusion-weighted imaging, the mass showed no restriction of diffusion. The mass had displaced the right testis to the left. No evidence of any extrascrotal extension into the abdomen was noted (Fig. ). The radiological diagnosis was multiple scrotal hyadrocele or lymphatic malformation/lymphangioma. Since right scrotal swelling was progressing, surgery was performed.\nSurgical findings showed that the mass existing in the right scrotum had probably originated from the internal spermatic fascia. Microscopic examination revealed membranous tissue with some hemorrhage. Tissue thought to represent a thin wall of the cystic mass was identified as fibrous tissue with hemorrhage. Infiltration of lymphocytes around the small vessels was detected. Pathological findings were consistent with lymphatic malformation/lymphangioma.
