Female, 52 years old. Reason: hx of stroke in multiple territories, current headaches History: as above There is encephalomalacia involving the right frontal and left occipital lobes from chronic infarcts. These areas showed acute/subacute infarct on the prior study dated 11/2005. There is additional minimal scattered periventricular white matter FLAIR hyperintensity, without associated diffusion restriction. There is no evidence of acute infarct, intracranial hemorrhage, mass or edema. There is minimal ex vacuo dilatation of the frontal horn of the right lateral ventricle. Otherwise, the ventricles and basal cisterns are normal in size and configuration. No abnormal extra-axial fluid collection is identified. There is no midline shift or mass effect. The midline structures and craniocervical junction are within normal limits. Normal flow-voids are demonstrated in the major intracranial vascular structures. There is mild left maxillary sinus mucosal thickening. There is minimal scattered bilateral mastoid air cell opacification. The orbits are unremarkable.
Chronic encephalomalacia involving the right frontal and left occipital lobes, without evidence of acute infarct or other acute intracranial abnormality to account for the patient's symptoms.
