Status post cardiac arrest with no movement of LUE. Focal neurological signs. Status post intubation.There is an area of focal low density in the right occipital lobe with loss of the gray-white matter differentiation and sulcal effacement consistent with an acute infarct is seen.A second area of area of focal low density in the right frontal lobe posteriorly extending to the right precentral gyrus is seen. The overlying gray matter is preserved. There is no associated ex vacuo dilatation of the anterior horn of the right lateral ventricle and the age of this lesion is indeterminate. Overlay of an acute infarct in this region cannot be excluded on CT and MRI is more sensitive at detecting acute ischemia/infarct.There is no evidence of intracranial hemorrhage, hydrocephalus or midline shift. There are background changes of periventricular low attenuation consistent with chronic small vessel ischemic change. The ventricles and basal cisterns are normal in size and configuration.There is diffuse thickening of the calvarium particularly marked over the frontal bones and sphenoid wings. The skull base appears unremarkable and the visualized paranasal sinuses and mastoid air cells are normally pneumatized and clear.
*Probable acute infarct in the right occipital lobe.*There is a second area of low density in the right frontal lobe posteriorly, age is indeterminate. Overlay of an acute infarct in this region cannot be excluded on CT and MRI is more sensitive at detecting acute ischemia/infarct.*Mild chronic small vessel ischemic change is demonstrated.
