11 years Female (DOB:9/2/2005)Reason: AVM, history intracranial hemorrhage, resection and radiation, yearly follow up History: yearly surveillance.PROVIDER/ATTENDING NAME: DAVID M. FRIM DAVID M. FRIM MRI of the brainNo diffusion weighted abnormalities are appreciated.There are numerous flow voids present in the left parietal lobe. An area of encephalomalacia and gliosis is present in the left parietal lobe adjacent to the AVM. Patient status post left-sided craniotomy. The left middle, anterior and posterior cerebral artery vasculature appears larger than the right middle, anterior and posterior cerebral artery vasculature.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries. The left middle cerebral artery vasculature appears larger than the right middle cerebral artery vasculature. The left posterior cerebral artery vasculature appears larger than the right posterior cerebral artery vasculature. The left anterior cerebral artery vasculature appears larger than the right anterior cerebral artery vasculature. Venous drainage appears to be superficially draining.The prior exam was limited, however, based on the cerebral artery caliber and appearance, the AVM has not changed significantly.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified. The posterior communicating arteries are not readily identified. The vertebral arteries are similar in size.
1.Status post left parietal lobe surgery for arteriovenous malformation. There is persistence of arteriovenous malformation in the left parietal lobe. The prior exam was limited, however, based on the cerebral artery caliber and appearance, the AVM has not changed significantly. Follow-up surveillance exams inclusive of the entire head and possible with time resolved MRA would help further assess. 2.Status post left parietal surgery for AVM removal.3.Encephalomalacia adjacent to the AVM.
