Description
Summary:	To report isolated upgaze palsy in a patient with a dolichoectatic vertebrobasilar artery. We report a 48-year-old man who showed upgaze palsy and convergence insufficiency. The left vertebral artery and basilar artery were shown to be greatly expanded, elongated and tortuous in cranial magnetic resonance imaging (MRI). The vertebrobasilar artery runs along the sulcus basilaris superior to the pontomesencephalic junction. A dolichoectatic basilar artery may result in compression of midbrain structures related to vertical gaze.
