  • Oncocytic Neoplasms: Facts
    - Fairly common diagnosis (9% of SRMs)
    - No technique to differentiate oncocytic RCC from oncocytoma with 100% reliability from imaging or biopsy
    - Hybrid tumors: oncocytoma and RCC coexist in one tumor in up to 17% of “oncocytomas”
  • CT Urography: Indications
    - Hematuria
    - High risk of upper urinary tract malignancy
         - New bladder carcinoma patients
