Headache after trauma. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are scattered foci of cerebral white matter T2 hyperintensity. 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, paranasal sinuses, and scalp soft tissues are grossly unremarkable. There is fluid within the right mastoid air cells.
Scattered foci of cerebral white matter T2 hyperintensity are nonspecific, but may represent chronic small vessel ischemic disease. No evidence of acute intracranial hemorrhage, mass, or acute infarct. Fluid in the right mastoid air cells may indicate mastoiditis.
