MRI Findings of Uterine Lipoleiomyoma Correlated with Pathologic Findings

OBJECTIVE: Our objective was to describe the MRI findings of uterine lipoleiomyoma and to correlate them with histopathologic findings. CONCLUSION: Uterine lipoleiomyoma typically presents as a well-demarcated mass showing hyperintensity with hypointense amorphous bundles on T1- and T2-weighted images with chemical shift artifacts. The hyperintense region suppressed on chemical shift fat-suppressed sequences and the hypointense bundles enhanced by contrast material pathologically correspond to mature fat tissue and smooth muscle tissue, respectively. Even in an atypical case with a small volume of fat tissue in the mass, a fat-suppression MRI sequence is especially useful for the diagnosis.
