Mould meningitis associated with intravenous drug use

Abstract

Fungal meningitis is most commonly causes by Cryptococcus species and dimorphic fungi. We present a rare case of mould meningitis, ventriculitis and subependymal nodules in an immunocompetent patient, having likely seeded the meninges and ventricular system through intravenous drug use. The causative mould remains undetermined. The case highlights the poor sensitivity of CSF culture and the need to consider surgical biopsy where there is diagnostic difficulty and fungal infection is being considered.
