We describe a rare case of neurovascular compression syndrome (NVCS) of the brain stem and opsoclonus-myoclonus syndrome (OMS) complicated with vestibular paroxysmia (VP) and autonomic symptoms. Moreover, we discuss the case with respect to the available information in medical literature. A 36-year-old man with vertigo and nausea had difficulty standing, and was transported by an ambulance to our hospital. He had VP, opsoclonus, cervical myoclonus, anxiety, and restless legs syndrome. Magnetic resonance imaging at hospitalization showed that the dolichoectatic vertebral artery was in contact with the postero-lateral side of the pontomedullary junction. He was diagnosed with NVCS of the brain stem (most likely of the input to the vestibular nucleus) associated with contact with the dolichoectatic vertebral artery. Combination therapy using multiple antiepileptic drugs, such as low-dose carbamazepine, clonazepam, and lacosamide, improved his clinical symptoms. He was finally able to walk and was discharged on day 42 after admission. He is being routinely followed-up since then. Further research is needed to confirm the validity of the combination therapy.
