Drop attacks, with seizure. There is a curvilinear area of susceptibility effect in the region of the right hippocampal tail and posterolateral thalamus. There are mild areas of cerebral white matter T2 hyperintensity bilaterally, predominantly in a periventricular distribution. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles and basal cisterns are normal in size and configuration, without evidence of colloid cyst. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is a left maxillary sinus retention cyst.
A curvilinear area of susceptibility effect in the region of the right hippocampal tail and posterolateral thalamus may represent prior hemorrhage. Areas of cerebral white matter T2 hyperintensity bilaterally, may represent chronic small vessel ischemic disease.
