Bilateral papilloedema in Camurati-Engelmann disease

A 23-year-old woman presented with bilateral papilloedema in a setting of Camurati-Engelmann disease (CED). She was investigated with neuroimaging showing no optic nerve canal stenosis or jugular vein canal compromise. Her MRI venogram was normal. Her opening pressure at lumbar puncture and serum alkaline phosphatase were raised. Her papilloedema resolved with long-term use of acetazolamide. We believe that our patient suffered from raised intracranial pressure directly as a result of decreasing intracranial volume secondary to CED.
