Oncocytoma. An 83-year-old female with melanoma of the right arm. ¹⁸F-FDG PET/CT (A) revealed a strongly glucose avid lesion in the right parotid gland. The lesion shows heterogeneous signal intensity on both T1- (B) and T2-w (C) images. The coronal turbo inversion recovery magnitude (TIRM) image (D) shows the slightly lobulated structure. There is heterogeneous enhancement of the lesion on the T1-w fat saturated image after gadolinium injection (E) and slight diffusion restriction as seen on the b800 image (F) with high signal intensity and corresponding low signal intensity (o) in the ADC map (G)
