Diagnosis: Compression of brainClinical question: Chiari malformation , no surgery, yearly follow up , please do with CSF flow study. The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology.The cerebellar tonsils are low lying and pointed. It extend approximately 11 mm below the level of the foramen magnum.CSF flow is mildly diminished at the level of the foramen magnum.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. There is a left lateral recess disk protrusion at this level associated with small uncovertebral osteophytes and encroachment of the left sided exiting nerve roots. This is stable compared to the prior exam.At C4-5 there is no significant compromise to the spinal canal. There are minor degenerative changes at the lateral recesses.At C5-6 there is no significant compromise to the spinal canal or the 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.Some scattered opacities are present in the mastoid air cells.
1.Findings are compatible with Chiari I malformation. CSF flow is mildly diminished at the level of the foramen magnum.2.There is no evidence for a syrinx.3.There are some degenerative changes present in the cervical spine with some encroachment of exiting nerve roots within the left neural foramen at C3-4. This is stable.
