The vast majority of primary malignant renal tumors are clear cell carcinomas (RCC). However, there are various other tumors including papillary, chromophobe, medullary and translocation related RCC. Further, there are also rare mesenchymal renal malignancies including lymphoma and sarcoma. The purpose of this educational exhibit is to describe the imaging spectrum and management of primary renal neoplasms.

Educational Goals / Teaching Points
This educational exhibit will describe the incidence and histopathological features of primary renal neoplasms, discuss the typical and atypical imaging features, discuss the role of MRI and PET CT in staging of these tumors, and describe the current management of the primary renal neoplasms.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
CT and MRI are the most commonly used imaging modalities used to assess primary renal neoplasms. We will discuss the imaging protocol for evaluation of primary renal neoplasms. Imaging features of the various histological subtypes will be discussed in this exhibit.

Imaging plays a very important role in the diagnosis and follow-up of primary renal neoplasms. Although nonclear cell RCCs are rare, radiologists should be aware of the clinical and multimodality imaging features that will aid in the early detection and optimal management of patients with these primary renal neoplasms.
