Bilateral papilledema with normal CT-scan in neurosarcoidosis.

A 74-year-old woman was admitted with fever, muscle and joint pain and a mild hypercalcemia. Rather suddenly she turned unconscious and bilateral papilledema was found. A subsequent CT of the brain, however, did not disclose signs of space-occupying masses or increased intracranial pressure. She died two days later and at autopsy there were no signs of incarceration. Microscopic examination revealed non-caseating epithelioid granulomas throughout the meninges and brain consistent with sarcoidosis.
