成人に発生した陰嚢内リンパ管腫の1例

Abstract

We reported a rare case of intrascrotal lymphangioma in an adult. A 31-year-old man visited a urological clinic with a chief complaint of left scrotal swelling since a few days ago, and was pointed out to have a left intrascrotal cystic mass. The patient was sent to our hospital for further examination in 23 April 2008. The left scrotal mass was palpated elastic hard below the left testis and its surface was irregular. Light transillumination test showed positive. Ultrasonography revealed a cystic mass 7.0×4.4×4.5 cm with multiseptate accumulation at the lower pole of the left testis. Magnetic resonance imaging showed low intensity by T1WI and high intensity by T2WI, suggesting a protein-rich component. We suspected left intrascrotal lymphangioma and extirpated the scrotal mass under lumbar anesthesia. Pathological examination demonstrated lymphangioma. The patient had no evidence of recurrence after 1 year.
