The nervus glossopharyngeus (CN IX), nervus vagus (CN X), nervus accessorius (CN XI), and posterior inferior cerebellar artery were viewed at the inferior compartment of CPA (Figure 3).
Special attention should be put on the anatomical proximity to nervus vagus, nervus glossopharyngeus, nervus hypoglossus, and nervus laryngeus superior as well as to arteria carotis interna [3-5].
Although the relationship between MRS and ARDS is unknown, in the patient with MRS, among the secondary symptoms of MRS (present in more than 80% of the cases), those derived from the involvement of other cranial nerves (olfactorius, vestibulocochlearis, glossopharyngeus, hypoglossus, and trigeminus) are more frequently found.
