The cause of the arachnoiditis was subarachnoidal bleeding due to rupture of an internal carotid artery aneurysm. The aneurysm was clipped 5 years after the first episode of bleeding. The diagnosis of optochiasmatic arachnoiditis was confirmed during the operation. This case is presented in order to discuss the causes, the symptoms and the therapeutical possibilities of this rare condition.
