  • within superficial part of vastus lateralis muscle
  • abutts fascia
  • separate from bone


  • hypoechoic without calcification / cystic changes
  • lobulations present
  • posterior acoustic enhancement present

The lesion is a solid tumor with vascularity involving muscle of thigh. There was echogenic cap at proximal and distal end of lesion which is described in myxoma; however, there were few points against that diagnosis.

Surgical excision was done. Histopathological diagnosis: Schwannoma.
