Diagnosis: Compression of brainClinical question: eval postop changesSigns and Symptoms: s/p Chiari decompressionComments: Please also do CINE flow sequence. | The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. The patient is status post posterior fossa decompression since the prior exam. There are postsurgical changes present with blood products, air bubbles and fluid accumulating at the surgical site. There is some signal change present within the cerebellar tonsils associated with some blood products.CSF flow study indicates impeded flow through 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 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.The patient status post recent posterior fossa decompression for Chiari I malformation. There is some postoperative change present with fluid and edema accumulation at the surgical site. CSF flow study suggests impeded flow at the level of the foramen magnum.
