Eosinophilic Solid and Cystic Renal Cell Carcinoma: Imaging Features of a Novel Neoplasm

Eosinophilic solid and cystic renal cell carcinoma (ESC RCC) is a recently described entity with distinct clinical, pathological and molecular features. However, the radiologic aspects of ESC RCC have not been characterized.

In this report, we describe the imaging findings of two ESC RCC's. We found two distinct imaging patterns that varied depending on histopathologic features (solid or cystic predominance). In conclusion, it is important to know the imaging characteristics and pathological correlation of this novel neoplasm to increase its recognition and improve the decision-making process.
