35 African Female 4 months Hip pain, hx asthma and IBD, ? Incidental Finding, please help MRI

Based on the history I presume I was looking for AVN, but there is no AVN,
just normal cellular red marrow.
There is a small cortically based stress fracture deep to the anterior base
of the femoral neck (white arrows), with minimal BME, presumably chronic,
consistent with history.
She has a tiny apical labral tear at 2:00 I don’t show.

What is the smooth stripe of bright PDFS signal along the anterior femoral
neck, red arrows?
It seems incidental, but I don’t know what it is. Do you?
