 MRI: There is a masslike lesion in the right parietal lobe with moderate surrounding edema and regional mass effect. The lesion demonstrates very mild susceptibility, which could represent blood products or mineralization. The ventricles and sulci are within normal limits. The basal cisterns remain patent. There is no midline shift. 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: The intracranial internal carotid arteries are normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. 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: The superior sagittal sinus, inferior sagittal sinus, transverse sinuses, 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.Mass lesion in the right parietal lobe with moderate surrounding vasogenic edema and regional mass effect without significant midline shift or evidence of herniation.2.Unremarkable intracranial vasculature.Findings discussed with the ordering team. MRI with contrast/perfusion imaging to follow.
