66-year-old female presents with a new onset headache, evaluate for space-occupying lesion. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild scattered periventricular and subcortical white matter T2 hyperintensity. There is mild diffuse cerebral volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. There is minimal mucosal thickening in the bilateral maxillary sinuses. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is left mastoid air cell fluid.
1. Nonspecific cerebral white matter abnormality may represent chronic small vessel ischemic disease. Otherwise, no evidence of intracranial hemorrhage, mass, or acute infarct. 2. Left mastoid air cell fluid may represent mastoiditis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
