F 62, left hip pain. Suspected impingement.
There’s a subchondral / subcortical bone lesion at the anterior aspect of the left femoral head with cystic and fatty components, possibly also some calcification.
To me it doesn’t look like a typical impingement lesion / herniation pit.
More like cystic degeneration of an intraosseous lipoma, or an LSMFT.
She also has chondropathy with subchondral cysts and mild trochanter bursitis (not shown).
