Dizziness and giddiness BRAINThe CSF spaces are appropriate for the patient's stated age with no midline shift. There are calcifications present along the globus pallidiNo 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. There is an arachnoid granulation present along the junction of the right transverse sinus with the sigmoid sinus.The visualized portions of the paranasal sinuses demonstrate partial opacification of the left maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.IACNo abnormal foci of enhancement are appreciated within the internal auditory canals. The cochlea and semicircular canals appear intact. The cochlear nerve can be followed bilaterally tracking into the cochlea. The modiolus is well formed bilaterally.The left superior semicircular canal extends to the tegmen tympani. It is not clearly dehiscent on the basis of this exam.No abnormal enhancing lesions are appreciated at the cerebellopontine angle cisterns nor the internal auditory canals.
1.The left superior semicircular canal extends to the surface of the tegmen tympani. It is not clearly enhancement, however, CT temporal bones is more accurate in evaluating for this.2.No abnormal mass lesions are appreciated intracranially.
