 Again seen is an encephalomalacic cavity in the left frontal lobe with redemonstration of susceptibility signal consistent with hemosiderin deposition at the site of the previously known left anterior frontal hematoma. This is unchanged from the previous study and measures 27 x 9 mm.Multifocal punctate T2 high signal foci are seen in the periventricular white matter space consistent with mild nonspecific small vessel ischemic changes. Unchanged small right middle cranial fossa arachnoid cyst. No evidence of acute infarct. No new hemorrhage. No new mass or mass effect. No hydrocephalus. Major flow-voids are preserved. Trapped secretions again noted in the right petrous apex which is pneumatized. Left ethmoid sinus fluid noted.
1. Chronic hemorrhagic cavity in the left frontal lobe appears similar to prior. Mild chronic small vessel ischemic changes. No new infarct or hemorrhage. 2. If evaluation of the previously treated aneurysm is desired, an MRA or CTA can be considered.
