14 years Female (DOB:12/17/2001)Reason: 14 yo F with hx cerebral AVM, s/p coil embolization and craniotomy, eval vasculature History: worsening HA and vomitingPROVIDER/ATTENDING NAME: SANGHYUN MARGARET PAIK STEPHEN THOMAS MRI of the brainThere is redemonstration of encephalomalacia involving the majority of the right frontal lobe. There is associated ex vacuo effect on the right lateral ventricle. There are some foci of susceptibility effect present within the right frontal lobe. Smaller focus of encephalomalacia is present along the medial aspect of the left frontal lobe anteriorly. This appears to have extended since the 6/27/2015 exam but not significantly changed since the 1/6/2016 CT of the head..The patient is status post right frontal craniotomy and embolization of a right frontal lobe vascular lesion.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.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.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified and is medium size. The posterior communicating arteries are intact. The vertebral arteries are similar in size.
1.Encephalomalacia involving large portion of the right frontal lobe and a small portion of the left frontal lobe. 2.No evidence for intracranial arteriovenous malformation.
