Management of Metastatic Nonclear Renal Cell Carcinoma: What Are the Options and Challenges?

Abstract

A 68-yr-old female patient presented to the accident and emergency department following a car accident with head injury. Computed tomography (CT) of the head revealed a mass in the lateral region of the skull. No further findings were evidenced within the brain structures. The patient had a history of breast cancer with positive lymph nodes, for which she received adjuvant chemotherapy and combined hormonal therapy following mastectomy. She underwent surgical excision of the skull mass. Histology confirmed a poorly differentiated carcinoma of unknown origin. A fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT scan revealed an avid 2 cm mass on the left kidney
