Reason: evaluate source of headache History: headache, nocardia pneumonia. There is no evidence of intracranial hemorrhage, mass, or acute infarct. Scattered periventricular and subcortical T2 hyperintensities without diffusion restriction or enhancement are nonspecific. A few scattered punctate foci of susceptibility are likely the result of chronic hypertension. Small left peripheral PICA territory focus of chronic ischemia is unchanged There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull and scalp soft tissues are grossly unremarkable. Mild bilateral mucosal thickening of the maxillary sinuses
1.Overall stable exam with a few scattered punctate foci of T2 hyperintensity which are nonspecific with differential including chronic small vessel ischemic disease, demyelinating disease, chronic migraine sequale and other inflammatory etiologies.2.Associated mild scattered foci of susceptibility are unchanged and likely the result of chronic hypertension.
