Lymphangioma presenting as a small renal mass during childhood.

Abstract

Renal lymphangioma is a very rare lesion. A case of lymphangioma that presented as a small, hyperechoic renal mass on sonography in a child is reported. On CT, the lesion appeared as a low-density, enhancing renal mass. Despite its rarity, lymphangioma should be considered in the differential diagnosis of such a lesion. A suspected lymphangioma may be evaluated by percutaneous biopsy.
