An ill defined cortical and subcortical lesion of altered signal is seen involving the left inferior frontal gyrus centered on pars triangularis (Broca's area). The lesion displays low T1, bright FLAIR signal intensity and mixed signal on DWI/ADC. On post contrast study the lesions shows gyral pattern of enhancement. There is no significant mass effect. MRS reveals mild reduction of NAA and marked elevation of lactate peaks. No significant rise of Cho peak.
