Left parieto-occipital intracerebral hemorrhage. Possible diagnosis of arteriovenous malformation. There is a 37 mm x 26 mm x 41 mm sized left parieto-occipital intracerebral hemorrhage with the surrounding edema.There is a mass effect towards left lateral ventricle occipital horn, however, there is no evidence of midline shift or transtentorial herniation.There is no evidence of acute ischemic infarct.There is a prominent vascular structure arising from anterior superior aspect of the intracerebral hemorrhage, otherwise there is no evidence of significantly increased vascularity.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses are clear. There are fluid collections on the right mastoid air cells.3D MRV brain post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, left transverse sinuses, left sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus. Right transverse and right sigmoid sinus as well as right jugular bulb are not visualized on this MR venogram but prominent right occipital venous plexus which may indicate hypoplastic right side dural sinuses which is a normal variation..
1, Acute ICH with surrounding edema on the left parieto occipital lobe.2. A prominent vascular structure was seen on superior and anterior aspect of the ICH, otherwise no remarkable finding. 3. No other abnormal enhancing lesion.4. Normal MR venogram with hypoplastic right side transverse and sigmoid sinuses.
