 There is no evidence of intracranial hemorrhage or mass. There are punctate foci of restricted diffusion in the left superior frontal sulcus and precentral gyrus. There is otherwise a small area of encephalomalacia in the left precentral gyrus. Additional scattered punctate foci and confluent areas of T2 hyperintensity within the periventricular and subcortical white matter without associated restricted diffusion. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There are bilateral maxillary osteointegrated dental implants and sinus lift surgery.
1. Punctate foci of restricted diffusion in the left superior frontal sulcus and precentral gyrus may reflect acute to early subacute ischemia superimposed upon an otherwise small chronic infarct involving the left precentral gyrus and a background of diffuse mild chronic small vessel ischemic disease.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
