From the case: Tuberculous arthropathy (right hip joint)
Images show superolateral migration of the right femoral head with narrowing of the right hip joint space. The right femoral head is flattened with irregular cortical outline and cartilage erosions. The apposing articular surface of the right acetabulum also shows irregular cortical outlines. STIR hyperintense and T1W hypointense signals are seen in the right femoral head, neck and proximal shaft as well as in the right acetabulum and surrunding hip muscles. T1W hypointense and T2W hyperintense reticular or lace-like patterns are seen in the subcutaneous fat at the lateral aspect of the right hip.
