title: PNET/Ewing's sarcoma of the kidney: imaging findings in two cases.
abstract: The CT-imaging findings of primary renal PNET/Ewing's sarcoma in two patients were retrospectively assessed. A large renal mass with heterogenous contrast enhancement and necrotic and hemorrhagic areas were the predominant characteristics. In adolescents or young adults presenting with a large renal mass, PNET/Ewing's sarcoma may be included in the differential diagnosis.
