Imaging Appearances of Uterine Lipoleiomyoma With Pathological Correlation—Report of Two Cases and Literature Review

In Brief Lipoleiomyomas are benign uterine neoplasms arising from the myometrium and composed of smooth muscle cells and mature adipocytes. We describe imaging and pathologic features of these rare neoplasms. In the first case, postcontrast computed tomography showed a well-demarcated mass with a large central core of fatty tissue. The tumor in the second case showed atypical magnetic resonance imaging findings. Fat content was minimal and followed the signal intensity of subcutaneous fat, appearing hyperintense on T1-and T2-weighted sequences. Fat-suppression sequences are useful in such cases for confirming the diagnosis. We have described the computed tomography and magnetic resonance imaging features of uterine lipoleiomyomas and the role of imaging in the diagnosis and surgical planning.
