View larger version (196K): [in a new window]   FIG 1. Fluid-attenuated inversion recovery MR images of the brain acquired 9 days after a repair of long-bone fractures show multiple focal lesions in the periventricular, deep, and subcortical white matter. These are characteristic of CFE.

View larger version (183K): [in a new window]   FIG 2. Contrast-enhanced MR images of the brain show focal enhancement in many of the white matter lesions.

View larger version (179K): [in a new window]   FIG 3. T2*-weighted gradient-echo MR images of the brain show a single focus of susceptibility (arrow in C) in the left frontal white matter. This finding suggests a preexisting focus of hemorrhage from axonal shear injury or CFE or both. However, hemorrhage was not a predominant feature of the multiple white-matter lesions arising from CFE in this case.
