61 years Female (DOB:11/30/1954)Reason: Left hemi sensory disturbance and face pain History: abovePROVIDER/ATTENDING NAME: THOMAS J. KELLY THOMAS J. KELLY The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 22 x 15 mm axial dimension CSF collection adjacent to the right cerebellar hemisphere which could represent a small arachnoid cyst.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. The right vertebral artery is very small. There appears to be fetal origin of the right posterior cerebral artery.The cerebellar tonsils extend 1 mm below the level of the foramen magnum.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.
1.No intracranial lesions appreciated which can explain the patient's hemisensory disturbance. There is a small arachnoid cyst present in the posterior fossa.2.There is a small right-sided vertebral artery which could simply be congenital. If there is clinical concern for right vertebral artery disease, specific imaging of vertebral arteries may be of benefit.
