===Choice of modality===
*'''Ultrasonography of superficial soft tissues''' is the investigation of choice in stable superficial soft tissue masses of unknown origin, at least in flexion surfaces of large joints (groin, popliteal fossa, armpit and cubital fossa).
*'''MRI''' is the imaging modality of choice in suspected lipoma, with superior sensitivity of distinguishing it from liposarcoma as well as mapping the surrounding anatomy.<ref>{{cite web|url=https://radiopaedia.org/articles/lipoma|title=Lipoma|author=Rohit Sharma and A.Prof Frank Gaillard et al.|accessdate=2018-09-27|website=Radiopaedia}}</ref>
