Cervical Myelopathy Due to Direct Cord Compression by Posterior Inferior Cerebellar Artery Associated with Aberrant Vertebral Artery.

Background: The effectiveness of surgical microvascular decompression (MVD) of the vertebral artery (VA) for treating conditions such as trigeminal neuralgia or hemifacial spasm is well known. However, the use of MVD for a case in which the posterior inferior cerebellar artery (PICA) is directly compressing the high cervical cord has not been reported.

Case Description: A 48-year-old male was diagnosed with a rare case of myelopathy due to the PICA directly compressing the high cervical cord.
