These may be diagnosed with ultrasound, computed tomography (CT) or magnetic resonance (MR) imaging. On ultrasound, the mass appears quite echogenic, a pathognomonic finding. There is accompanying posterior acoustic shadowing.
CT demonstrates lipoleiomyomas as low attenuation lesions (< 20 HU). MR reveals a lesion that follows subcutaneous fat signal on all sequences. It is important to differentiate a lipoleiomyoma from a cystic ovarian teratoma, as the latter necessitates excision.
