The previously described lesion appears lobulated of intermediate signal intensity on T1WI with a peripheral rim of low signal, inhomogeneous high signal intensity on T2WI with areas of low signal intensity (due to hemosiderin or fibrosis) with intense and heterogeneous enhancement following IV contrast. A cortical rupture is noted at the anteroinferior aspect of the femoral neck with mild periosseous extension as well as adjacent bone marrow. mild joint effusion is noted.
