32 years Female (DOB:1/1/1984)Reason: Chiari with new vision changes and headaches/dizziness, sp decompression, please do with csf flow History: headache, dizziness and vision changesPROVIDER/ATTENDING NAME: DAVID M FRIM DAVID M FRIM MRI brain:The CSF spaces are appropriate for the patient's stated age with no midline shift. There appears to be some bidirectional flow at the level of foramen magnum.The patient status post suboccipital craniotomy and C1 posterior arch surgery for Chiari decompressionNo abnormal enhancing mass lesions are appreciated within the brain parenchyma. 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 a small mucous retention cyst. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRI orbits:The eyeballs are intact. No intraconal or extraconal space mass is identified. The extraocular muscles are intact. The lacrimal glands are symmetric and within normal limits in size and configuration. The suprasellar cistern is intact .
1.There is no evidence for an intraorbital mass.2.Some bidirectional flow present at the level of the foramen magnum which may suggest that there is some mild impedance to CSF flow at the level of the foramen magnum. There is no evidence for ventriculomegaly on this exam.3.Status post Chiari I decompression.
