Here, we report a case of vertebral artery aneurysm causing dysphagia in a 56-year-old man who had no remarkable past history. Two months before the first visit, he developed posterior neck pain followed by difficulty swallowing 1 month later. He was referred to our clinic because of gradually worsening dysphagia. Physical examination showed paralysis of cranial nerves IX, X, and XII; therefore, he was hospitalized. Because enhanced CT and MRI showed a partially thrombosed right vertebral artery aneurysm, he was transferred to the care of the Department of Neurosurgery. Parent artery occlusion of the right vertebral artery aneurysm was performed and it improved his symptoms. After regaining his ability to take in liquid food, he was transferred to another hospital for further rehabilitation. In this case, we attributed the dysphagia to aneurysmal compression of the roots of cranial nerves IX, X, and XII. A partially thrombosed cerebral artery aneurysm may often rupture and cause worsening of neurologic symptoms. The prognosis is generally poor because the rupture rate is extremely high especially with large or giant aneurysms. However, this case had a good clinical course owing to treatment by parent artery occlusion.
