Complex renal mass in 50-year-old male: T 2WI (A) show internal hypointense contents and linear structures with no definite post-contrast enhancement on post-gadolinium (B) images. Ultrasonography (C) showed a complex mass with echogenic solid-appearing area showing no colourflow on Doppler. In absence of daughter vesicles, maternal matrix and detached membranes, diagnosis of hydatid seemed unlikely. The histopathological diagnosis was papillary renal cell carcinoma. T 2WI, T 2 weighted imaging.
