Magnetic resonance images of osteitis pubis A

Coronal T1 and matching fat-suppressed coronal PD-weighted magnetic resonance images demonstrate subarticular marrow changes of symphyseal degeneration and athletic osteitis pubis. Note areas of subchondral sclerosis (arrow), fatty change (Modic Type 2 signal abnormality identified by arrowheads), and signal hyperintensity indicating 'osteitis' (Modic Type 1 signal abnormality identified by thick arrows). These changes are bilateral but asymmetric.
