Male, 61 years old, with altered mental status. Image quality is degraded by motion artifact.No restricted diffusion is seen. There is a large region of encephalomalacia involving the left frontal lobe. More mild signal abnormality and encephalomalacia affect the posterior left parietal lobe. Nonspecific periventricular T2 hyperintensity is also seen.No large parenchymal or extra-axial hemorrhage is suspected, though image quality is not adequate to exclude the possibility of microhemorrhage. The ventricular system is within normal limits for size and morphology.
Within the limitations of a significantly motion degraded exam, no definite acute intracranial abnormality is detected.Areas of encephalomalacia and signal abnormality involving the left frontal and, to a lesser degree, the left parietal lobe suggest prior ischemic injury.
