55 years Female Reason: sudden hearing loss right ear History: eval for mass or other etiology Provider Name: MAUREEN CROWLEY MAUREEN CROWLEY BRAINThe CSF spaces are appropriate for the patient's stated age with no midline shift. No 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 redemonstration of a left temporal lobe developmental venous anomaly draining into the left basal vein of Rosenthal. No associated cerebral cavernous malformation or evidence for capillary telangiectasia is appreciated. There is redemonstration of asymmetry of the jugular bulbs and associated venous drainage with the right being significantly larger than the left. The left jugular bulb and associated venous drainage, as before, appears relatively small. There is redemonstration of an 8x11mm arachnoid granulation within the left transverse sinus.The visualized portions of the paranasal sinuses demonstrate mild mucosal thickening along the floor of the left maxillary sinus which is unchanged from the prior exam. 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.No abnormal enhancing lesions are appreciated at the cerebellopontine angle cisterns nor the internal auditory canals.
MRI of the brain and IACs are within normal limits.
