Status post aneurysm coiling, communicating hydrocephalus, VP shunt placement. Examination limited by susceptibility related to extracranial portion of the shunt catheter. Right temporal-parietal approach ventriculostomy catheter tip terminates in the midline right lateral ventricle, unchanged. The ventricles appear mildly dilated, but unchanged from the prior study. Chronic hemosiderin staining of the surface of the brain likely represents the sequelae from prior subarachnoid hemorrhage. Extensive white matter T2 hyperintensity is not significantly changed and most consistent with chronic small vessel ischemic disease. There is chronic dural thickening. The paranasal sinuses and mastoid air cells are unremarkable . Findings are seen status post stent assisted aneurysm coiling in the communicating segment of the right ICA. Decreased signal within the stented portion of the distal ICA is likely artifactual and is unchanged. There is no evidence for recurrent aneurysm. No significant stenosis is evident in the anterior or posterior intracranial arterial circulations.
1. Status post stent assisted aneurysm coiling in the communicating segment of the right ICA. No evidence of recurrent aneurysm is seen.2. Moderate-severe chronic small vessel ischemic changes without evidence of acute ischemia / infarction.3. Right temporal-parietal approach ventriculostomy catheter with stable ventriclar size.
