Male, 29 years old. Follow-up femoral neck stress fracture. Continued pain despite healed femoral neck fracture on x-ray and immobility. ACETABULAR LABRUM: Acetabular labrum is intact without evidence of tear.ARTICULAR CARTILAGE AND BONE: At the level of the lesser trochanter, there is decreased signal on T1 sequences which likely represents sclerosis with a punctate focus of increased signal (series 801, image 10) which may represent a nidus. Adjacent to the presumed sclerosis is bone marrow edema along the medial femoral neck. Alignment of the hip joint is anatomic. The articular cartilage is intact. SOFT TISSUES: The visualized soft tissues are unremarkable. ADDITIONAL
Apparent sclerosis along the medial femoral neck with a possible small nidus and adjacent bone marrow edema. Given that the patient's symptoms do not correlate with activity and have not improved with rest, these findings are highly suspicious for an osteoid osteoma or less likely a persistent stress fracture of the femoral neck.
