Brainstem dysfunction heralding disseminated cryptococcosis

Abstract

Cryptococcal meningoencephalitis is one of the most common central nervous system infections affecting immunocompromised patients. However, brainstem involvement is extremely rare and may represent a diagnostic challenge to clinicians. We report a non-HIV infected, chronically immunosuppressed, patient with fatal disseminated cryptococcosis presented with subcutaneous masses at both thighs and progressive brainstem dysfunction. Magnetic resonance imaging demonstrated multiple brainstem infarcts likely derived from small vessel vasculopathy. Anti-fungal treatment led to partial neurologic improvement but the patient succumbed to a fatal sepsis from hospital-acquired pneumonia.
