 MRI brain: There are no areas of abnormal signal or pathological enhancement. There is no diffusion abnormality. The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. MRA brain: The intracranial internal carotid arteries are normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. There are bilateral small P-comm arteries. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.MRV brain: The left transverse sinus is somewhat hypoplastic. The superior sagittal sinus, inferior sagittal sinus, right transverse sinus, sigmoid sinuses, straight sinus, vein of Galen, internal cerebral veins, and several visualized cortical veins are patent. There is no evidence of venous thrombosis.
1. No evidence of acute ischemia, hemorrhage or mass.2. Unremarkable MRA brain.3. No evidence of deep venous thrombosis.
