Patient History
24-year-old male with lateral hip pain and no known injury.
Findings
SKELETAL: Extensive osteoedema throughout the femoral head is confluent and extends along the lateral aspect of the femoral neck, supratrochanteric region, and to a lesser extent the trochanteric region. Growth plates are closed. No fatigue, stress, or insufficiency fracture.
PELVIS: The remainder of the pelvis is uninvolved. Normal red marrow hyperplasia for age.
JOINTS: Trace to 1+ joint effusion. No intra-articular synovitis.
ACETABULUM/LABRUM: Diminutive anterosuperior labrum seen only sagittally is a thin horizontal microtear and not likely related to the femoral head osteoedema.
MUSCLES/TENDONS/LIGAMENTS: Normal.
OTHER/SOFT TISSUE: Normal.
Conclusions
Diffuse osteoedema of the femoral head with trace hip effusion consistent with transient osteoporosis of the hip despite a slightly atypical demographic. Diminutive anterosuperior labrum.
