Persistent neurological symptoms and elevated intracranial pressures in a previously healthy host with cryptococcal meningitis
© 2023. The Author(s)..
Cryptococcal meningoencephalitis can occur in both previously healthy and immunocompromised hosts. Here, we describe a 55 year-old HIV-negative male with no known prior medical problems, who presented with three months of worsening headaches, confusion, and memory changes without fever. Magnetic resonance imaging of the brain demonstrated bilateral enlargement/enhancement of the choroid plexi, with hydrocephalus, temporal and occipital horn entrapments, as well as marked periventricular transependymal cerebrospinal fluid (CSF) seepage. CSF analysis yielded a lymphocytic pleocytosis and cryptococcal antigen titer of 1:160 but sterile fungal cultures. Despite standard antifungal therapy and CSF drainage, the patient had worsening confusion and persistently elevated intracranial pressures. External ventricular drainage led to improved mental status but only with valve settings at negative values. Ventriculoperitoneal shunt placement could thus not be considered due to a requirement for drainage into the positive pressure venous system. Due to this persistent CSF inflammation and cerebral circulation obstruction, the patient required transfer to the National Institute of Health. He was treated for cryptococcal post-infectious inflammatory response syndrome with pulse-taper corticosteroid therapy, with resultant reductions in CSF pressures along with decreased protein and obstructive material, allowing successful shunt placement. After tapering of corticosteroids, the patient recovered without sequelae. This case highlights (1) the necessity to consider cryptococcal meningitis as a rare cause of neurological deterioration in the absence of fever even in apparently immunocompetent individuals and (2) the potential for obstructive phenomena from inflammatory sequelae and the prompt response to corticosteroid therapy.
