Neuro-meningeal cryptococcal infection revealing a multiple myeloma.

Rare cases of Cryptococcus have been documented in patients living with multiple myeloma. To date there has been no documented evidence of cryptococcosis revealing multiple myeloma. We reported a 63-year-old man who had a 2-months history continuous holocranial headaches, morning vomiting, complaining of blurred vision and fever. The biologic and the imaging showed a Cryptococcus meningoencephalitis. The search for a cause of immunodeficiency revealed a multiple myeloma. The diagnosis for Cryptococcus was confirmed according to an India ink stain, blood and cerebrospinal fluid culture. The patient's treatment for multiple myeloma was initiated with a chemotherapy regimen. The evolution was good without complication. Cryptococcosis, especially in the neuro-meningeal form, is a serious, deadly opportunistic infection. The search of an underlining immunodeficiency must be systematic. In this case, it was associated with early stage multiple myeloma.
