Patient Data

Age: 20 years
Gender: Male
mri

Femoral head-neck asphericity with anterosuperior fibrocystic change. Anterosuperior perilabral sulcus.

Direct head rectus femoris origin is normal. Muscle belly edema of iliopsoas for a craniocaudal length of approx. 7.5 cm, approx 2.5 cm fiber disruption, involving 10-25% cross-sectional diameter, and extending to the iliacus myotendinous junction. Distal iliopsoas free tendon is intact. No iliopsoas bursal effusion. 

Gluteus minimus and medius tendons are intact. No trochanteric bursal effusion. Hamstring origin complex is intact. No ischial bursal effusion.

Case Discussion

The injury is a moderate iliopsoas muscle injury (BAC grade 2b). There is also cam morphology with fibrocystic change at the anterosuperior femoral neck, whether this is significant requires clinical assessment but is worthwhile raising in the young athlete.
