Optochiasmal arachnoiditis induced by muslin wrapping of intracranial aneurysms. A report of two cases and a review of the literature.

Muslin wrapping of intracranial aneurysms has been used for many years, but muslin-induced optochiasmal arachnoiditis was first reported only in 1978, as a complication with catastrophic loss of vision. In this study of 54 cases wrapped with muslin over the last six years, two cases of optochiasmal arachnoiditis occurred. Three patients had early rebleeding among the 27 who had wrapping as the only treatment of the aneurysm.
