Magnetic Resonance Imaging Findings of Multilocular Cystic Renal Cell Carcinoma and Clinical-pathologic Comparison.

Objective: Multilocular cystic renal cell carcinoma (RCC) is a unique type of renal carcinoma characterized by multi-loculated cystic masses. The aim of this study was to retrospectively evaluate the magnetic resonance imaging (MRI) findings of multilocular cystic RCC. Materials and Methods: All patients were examined by MRI. Two radiologists retrospectively evaluated MRI features, and compared radiological findings and Bosniak category with histopathological findings. Results: The patient population comprised seven men and three women with a mean age of 52.9 years (range:37-61 years). The margins of the multiloculated cystic masses were well defined in all patients, and there was no sign of infiltration of the adjacent tissue and metastatic lymphadenopathy. Conclusion: Multilocular cystic RCC exhibits non-malignant behavior and frequently has a long survival. The size of the lesion at diagnosis is variable, but there is no evidence of infiltration and metastasis in patients at diagnosis. [ABSTRACT FROM AUTHOR]
