Orbital pachymengitis secondary to Pseudomonas aeruginosa

Abstract

Pachymengitis is a very rare disorder that can present with multiple cranial neuropathies. The etiology can be inflammatory, infective or a combination of both, resulting in a thickening of the cranial dura and an obliteration of the individual layers of the meninges. We present a rare case of Pseudomonas aeruginosa pachymeningitis in the orbit that resulted in severe and permanent visual loss, in a patient after extensive sinus surgery.
