Reason: evaluate AVM and aneurysm (see former CTA and CTH reports done at UCM) History: headache The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a partially calcified 19 x 12 mm lesion located in the left inferior parietal lobule which is associated with larger flow voids in the left MCA territory.There is a moderate degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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.
1.Findings are suspicious for a small left inferior parietal AVM with suspected remote hemorrhage.2.Periventricular and subcortical white matter changes of a moderate degree are nonspecific. At this age they are most likely vascular related.
