Uterine Intravenous Leiomyomatosis with Cardiac Extension: Radiologic Assessment with Surgical and Pathologic Correlation

Figure 3

On MR images, the uterine tumor, approximately  cm in size, extensively involved the myometrium as a poorly demarcated diffuse lesion. (a) Axial T2-weighted image showed the lesion involving a few hypointense nodules (arrow) as having inhomogeneous high signal intensity (SI). (b) Axial T1-weighted image showed the lesion with a number of hyperintense tiny foci (arrow) as having low SI similar to that of the myometrium. (c) On the axial fat-suppressed T1-weighted image, the hyperintense foci within the lesion on T1-weighted images were suppressed (arrow), reflecting a lipomatous tumor. (d) On the contrast-enhanced fat-suppressed T1-weighted image, the lesion demonstrated strong contrast enhancement but contained several poorly demarcated hypointense areas, reflecting degenerative or necrotic changes. ((e), (f)) On diffusion-weighted images (e) and the ADC map (f), the lesion showed slightly high SI.
