Clinical question: Evaluate for hemorrhage. Signs and symptoms: Headaches and dysarthria. CT of brain without infusion:High density material within the right internal carotid artery is consistent with prior embolization and coil placement.A slightly high density loculated and calcific tissue surrounding the basal cistern and within the cavernous sinuses is consistent with patient's known significant atherosclerotic disease with ectasia and tortuosity of the vasculature. These findings appear similar to prior CT and MRI examinations.Extensive areas of encephalomalacia of the right cerebral hemisphere with ex vacuo dilatation of the right lateral ventricle remain identical to prior studies. Few small foci of low-attenuation likely small vessel strokes in the left hemisphere are also noted and stable.No evidence of hemorrhage, edema, mass-effect, midline shift or hydrocephalus.
No evidence of acute findings and stable exam since prior study.
