Migraine without aura, not intractable, without status migrainosus [G43.009] / Benign neoplasm of cerebral meninges [D32.0], Reason for Study: ^Reason: Evaluate for structural lesions as etiology of Headaches, hx moya moya, hx dvt History: Headaches, hx Brain MRIAbout 8.5mm (RL) x 11mm (AP) x 12mm (CC) sized extra-axial homogeneously well enhancing mass on the left frontal operculum area with low signal intensity on T1 weighted image and low signal intensity on T2 weighted image. There is no evidence of mass effects against adjacent brain parenchyme. Most likely differential diagnosis is again meningioma.There is no evidence of another abnormal enhancing lesion. There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D 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.Brain MRV3D MRV brain non enhanced Phase Contrast with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus.
1. Left frontal operculum area extra axial mass, unchanged in terms of size and MR characteristics since prior scan.2. No evidence of acute ischemic or hemorrhagic lesion.3. Normal brain MRA.4. Normal brain MRV.
