title: [Uncommon renal tumor in children].
abstract: We experienced six rare cases of solid renal tumor, which include two benign (CMN, MLCN) and four malignant tumors (CCSK 2, MRTK2). CMN is the most common benign solid tumor in the neonate. MLCN has typical US or CT findings manifested by multilocular cysts and thick wall septa. CCSK and MRTK are rare malignant neoplasms, which present characteristic clinical findings such as bone metastasis or intracranial metastasis. It is important for the radiologist to understand those characteristic clinical presentation of these tumors, because differential diagnosis is often impossible just on the basis of imaging.
