3 years, Male, new seizure with EEG abnormality. Seizure episode described as upper extremity shaking in patient's clinical notes. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. The sulci are normal in configuration, with no evidence of heterotopia. The hippocampi are symmetric. The corpus callosum is normal in appearance. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preservedThere are retained secretions within the mastoid air cells and middle ear, left greater than right. This results in asymmetry of blooming artifact on susceptibility weighted sequences at this level. Sella and orbits are grossly within normal limits. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No abnormality to account for seizure history.2. Significant left mastoid air cell and middle ear fluid opacification as compared to right, which is nonspecific. Please correlate clinically.
