Figure 2 (A-F): (A) A 10 year old female child with Stage II of Idiopathic Chondrolysis of Hip, presented with right loin pain for 8 weeks. (A), Fat suppressed coronal T2 weighted image shows a wedge shaped hyperintensity in the middle third of proximal right femoral epiphysis. Acetabular oedema was seen around the triradiate cartilage involving ilium and ischium. Altered signal intensity noted in the joint space, Pelvic tilting , Synovial thickening and joint effusion is also noted. (B) Axial T2 weighted image shows geographical hyperintensity in the anteromedial femoral head. surrounding muscles appear normal. (C and D) Coronal and Sagittal T1 weighted image with fat suppression after contrast shows mild heterogenous enhancement of the abnormal right femoral head area and junctional zone of the articular cartilage with bone. Visualised left hip shows no abnormal enhancement. (E and F) The followup MRI shows near complete restoration of the joint space and decreased wedge shaped abnormal focus in the femoral head.
