Figure 12.

Sagittal (a) and axial (b) T₂W images of an exophytic uterine lesion with a narrow base. The lesion demonstrates bridging vessels (White arrow) and cystic peripheral changes. The central area of enhancement and peripheral poor enhancement is seen on the T1 fat saturated imaging without (c) and with gadolinium contrast medium (d). DWI (e) and ADC (f) demonstrate central restricted diffusion within the lesion. Pre-operatively imaging suggested a torted large subserosal leiomyoma. However, on histology, a smooth muscle tumour of uncertain malignant potential was diagnosed. ADC, apparent diffusioncoefficient; DWI, diffusion-weighted imaging
