Brain. There is a partially thrombosed 42 x34 x34 mm giant aneurysm at the distal left vertebral artery and vertebrobasilar junction. The LVA ends in the aneurysm. The RVA is contiguous with the aneurysm distally and at the V-B junction along its medial aspect along a 10 mm segment and openly communicates with the distal portion of the aneurysm. The LVA ends in the aneurysm but supplies the aneurysm through the thrombus. There is extracranial origin of the right and left PICAs. There is a 16 x21 x24 mm pseudoaneurysm along the left cervical internal carotid artery at the C1 vertebral body level along the lateral aspect of the left ICAThere is opacification of the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries. The anterior communicating artery is identified and is small in size. The posterior communicating arteries are intact and small. The CSF spaces are appropriate for the patients stated age with no midline shift. There is a 42 x34 x34 mm well circumscribed premedullary and prepontine mass with mixed hyperdensity within it. The brainstem is displaced and compressed posteriorly by the mass and drapes over the mass. The inferior aspect of the 4th ventricle is narrowed and the foramina of Luschka are distorted. There is peripheral wall calcification present. The vertebral arteries and basilar artery are contiguous with this mass. A similar signal characteristic well-circumscribe mass is present in the left upper carotid space measuring 16 x21 x24 mm without wall calcifications. The temporal horns of the lateral ventricles are dilated. Overall there is mild enlargement of the third ventricle and lateral ventricles. The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
