44 year old female with stroke. Non-infused CT of brain.A focal area of lucency in the white matter of left frontal lobe extends from the level of floor of the anterior cranial fossa superiorly to the high convexity. This produces no definitive evidence of mass effect and is believed to represent an area of encephalomalacia. No definitive evidence of any cortical component is detected. There are no old films available for comparison. The size and distribution of this lesion is unusual for a subcortical stroke. Further evaluation with an MRI is recommended. CT examination of brain is otherwise unremarkable.CTA of the neck.There is good visualization of bilateral common carotid arteries, carotid bifurcations and bilateral internal carotid arteries in the cervical region. No evidence of any stenosis at any of these locations is detected.A dominant right vertebral artery and slightly smaller left vertebral artery is demonstrated and appear normal throughout their course and across the skull base. No pathology is Limited images of the aortic arch and the origins of the great vessels as well as the right brachia cephalic and bilateral subclavian arteries are unremarkable. The basilar artery and its branches are also visualized on reformatted coronal images and are within normal limits. Both supraclinoid internal carotid arteries and bilateral anterior cerebral arteries and middle cerebral arteries are also demonstrate no areas of a stenotic lesion.
