[Cryptococcal meningitis disclosed by visual loss in HIV negative patient with ventriculo-atrial shunting]. / Cryptococcose neuroméningée révélée par une baisse de l'acuité visuelle chez un patient atteint de neurosarcoïdose et porteur d'une dérivation ventriculoatriale.

INTRODUCTION: HIV infection is the main cause of cryptococcal neuromeningitis but other diseases may be associated with this infection. CASE REPORT: We report a case of cryptococcal neuromeningitis in a patient with sarcoidosis and ventriculoatrial shunting. The patient was successfully treated by effective therapy without device withdrawal. CONCLUSION: The relationship between cryptococcosis and sarcoïdosis has been already described and may be not fortuitous. However it remains a very rare complication of sarcoidosis. Because of its potential severity (mortality rate of 40%), the diagnosis of cryptococcosis should be evoked as a differential diagnosis of neuro-sarcoidosis.
