- Trauma possible

Patient
7
21-year-old female with recent history of trauma.

| 1. |
Axial
T1W MR image reveals intermediate signal intensity mass in
the region of the vastus intermedius muscle in the proximal
left thigh.
|
| 2. |
Axial
(FSE) T2W MR image reveals high signal intensity inhomogenous
mass with areas of decreased signal intensity coursing through
mass and surrounding edema. This finding has been reported
in early myositis ossificans correlating with cellular central
fibroblastic proliferation and a myxoidstroma.
