Role of Doppler sonography in the diagnosis of cystic lymphangioma of the scrotum.
Cystic lymphangioma is a congenital lymphatic malformation that is a rare cause of extratesticular scrotal masses in children; it is frequently misdiagnosed preoperatively. Complete excision is curative, but recurrence may result from incomplete excision. We report a case of cystic lymphangioma of the scrotum in a 3-year-old boy, which had been previously diagnosed as a hydrocele. Gray-scale sonography showed a multicystic extratesticular lesion; color Doppler sonography further characterized the lesion by showing blood flow within the septa. CT scanning ruled out extrascrotal involvement. The cystic mass was surgically resected. The appearance of the lesion both macroscopically and microscopically was consistent with a diagnosis of cystic lymphangioma. The child recovered uneventfully and was discharged on the third day after surgery; no evidence of recurrence was found in 6 months of follow-up. In such cases of scrotal masses in children, gray-scale and color Doppler sonography, followed by CT or MRI, are useful in diagnosing cystic lymphangioma, differentiating it from other lesions, and defining its extent, thus allowing proper surgical planning.
