Figure 1: 18F-fl ruorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) revealing well-encapsulated lesions arising from both the kidneys with no signifi cant radiotracer uptake consistent with renal angiomyolipomas (a and b; bold arrow). Another large lobulated mass with nonuniform radiotracer uptake was noted in mid and lower pole of the left kidney (b and c) which demonstrated heterogenous contrast enhancement on contrast-enhanced CT (CECT) in arterial phase (d and e) and delayed washout on venous phase (f and g). The hypoenhancing areas of the lesion on delayed venous fi lling demonstrated highest radiotracer uptake refl ecting perfusion-metabolism mismatch (c, e, and g; line arrow)
