ABSTRACT: Sunitinib is one of the most commonly used multikinase inhibitors for metastatic renal cell carcinoma. Myositis is one of the rarest known adverse effects of sunitinib. Presenting herewith one such case with its relevant imaging findings on FDG PET/CT and ultrasound.

ABSTRACT: We herein present a case of carcinosarcoma gallbladder with osteosarcomatous differentiation in a middle-aged woman. This is seen on 18F-FDG PET/CT study as an intensely FDG-avid mass in the gallbladder with foci of calcification due to the presence of osteoid. This is a rare malignancy with poor prognosis.

Secondary involvement of inferior vena cava is a common presentation in aggressive solid malignancies, especially arising from kidneys, adrenals, and hepatobiliary system, mostly resulting from local infiltration. Rarely, primary tumors are seen arising from vascular tissue. The Ewing family of tumors commonly arises from bone, but there is a high propensity of these tumors to originate from nonosseous sites of mesenchymal cell origin. We would herewith demonstrate a rare presentation of Ewing sarcoma, seen originating from inferior vena cava, presenting as extensive intravascular tumor thrombosis, evaluated on FDG PET/CT imaging in a 12-year-old girl.
