Locations

For the abdominal wall, see Ultrasonography of the abdominal wall.

Planning

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.[1]

Evaluation

Possible findings:

Lymph nodes

Lipoma/Liposarcoma

The latter case demonstrates the inaccuracy of ultrasound to properly distinguish lipomas from liposarcomas, so this case should have had MRI as a first investigation.
