It abuts the temporal horn of the right lateral ventricle. It is not associated with any significant contrast enhancement. It follows spinal fluid on all pulse sequencesNo abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate scattered opacities. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
