69-year-old male with history of end-stage renal disease and hypertension presents with a new onset headache for three weeks. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are unchanged. There is mild to moderate periventricular and subcortical cerebral white matter T2 hyperintensity, which has slightly progressed. There is a persistent cavum septum pellucidum, a normal anatomic variant. There is no restricted diffusion. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, mastoid air cells, and scalp soft tissues are grossly unremarkable. There is deformity of the right lamina papyracea. There is a small retention cyst in the right maxillary sinus.
Nonspecific cerebral white matter abnormality may represent chronic small vessel ischemic disease. Otherwise, no evidence of intracranial hemorrhage, mass, or acute infarct. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
