MRI features of a solid mass-like renal lymphangioma: case report

Renal lymphangioma typically manifests as a unilocular or multilocular cystic mass in the parapelvic or perirenal spaces. A solid mass-like lymphangioma rarely occurs and thus is hard to differentiate from a renal cell carcinoma. We encountered a case of a solid mass-like renal lymphangioma that was confirmed using percutaneous biopsy. The purpose of our case report was to describe magnetic resonance imaging features, to show the differential diagnoses, and to discuss the role of percutaneous renal mass biopsy.
