22 years Female (DOB:3/2/1994)Reason: chiari malformation s/p decompression, post op follow up MRI , new symptoms after surgery, please do with csf flow study History: new neck pain after surgeryPROVIDER/ATTENDING NAME: DAVID M. FRIM DAVID M. FRIM MRI brain:The patient is status post suboccipital craniectomy and removal of the posterior arch of C1 for Chiari decompression.No abnormal 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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.The left vertebral artery ends in the left posterior inferior cerebellar artery which has a coarse echoes down to the C1-2 level.A normal biphasic flow is present at the level of foramen magnum.MRI cervical spine:The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. At C2-3 there is no significant compromise to the spinal canal or neural foramina.At C3-4 there is no significant compromise to the spinal canal or neural foramina.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.
1.Status post posterior fossa surgery and C1 surgery for Chiari decompression. There is no evidence for obstruction at the level of the foramen magnum. There is no syrinx or ventriculomegaly appreciated.2.Low-lying left posterior inferior cerebellar artery.
