Seizures, partial complex. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild scattered cerebral white matter T2 hyperintensity. The hippocampi are unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration, including a mild cavum septum pellucidum. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, mastoid air cells, and scalp soft tissues are grossly unremarkable. There is extensive mucosal thickening and secretions within the right maxillary and anterior ethmoid sinuses and to a lesser degree the left frontal and anterior ethmoid sinuses.
1. Nonspecific cerebral white matter lesions may represent chronic small vessel ischemic disease, demyelination, prior inflammation, for example. Otherwise, no evidence of intracranial hemorrhage, mass, or acute infarct. 2. Extensive right osteomeatal unit pattern of sinus disease.
