Migraine, unspecified, without mention of intractable migraine without mention of status migrainosus [346.90], Reason for Study: ^Reason: Hx of migraine - but worsening headache. Check for mass lesion/AVM. Other test for MRA History: Headache No evidence of acute ischemic or hemorrhagic lesion on the scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. There is a developmental venous anomaly on the right basal ganglia draining through the caudate vein. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.There is no evidence of intracranial arterial aneurysm. There is no evidence of significant luminal stenosis or irregularity of intracranial arterial system.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Developmental venous anomaly on the right basal ganglia.3. No evidence of intracranial arterial aneurysm. No intracranial arterial luminal stenosis.
