Abstract:
Cryptococcus is a cosmopolitan fungus with tropism for the nervous system and a higher prevalence of infection in immunosuppressed patients. Neurological compromise caused by this microorganism mainly debuts as a meningeal syndrome (headache, fever, neck stiffness) with predominant encephalic involvement. In this report we present the rare case of a non-HIV patient with flaccid paralysis and peripheral nerve involvement due to crytpococcal meningitis. This is a 53-years-old woman, with a past-medical history of diabetes, who presented with dysarthria, unilateral peripheral facial paralysis, asymmetric ascending quadriparesis, generalized hyporeflexia and urinary retention. Neuroimaging was initially reported as negative for vascular or demyelinating diseases. Electrophysiological studies were performed, and acute flaccid paralysis of undetermined etiology was defined as a temporal clinical diagnosis. Cerebrospinal fluid molecular analysis confirmed the presence of Cryptococcus neoformans var. gatti; posteriorly, antifungal treatment with amphotericin B and fluconazole was started. Polyneuroradiculopathy symptoms significantly improved over the in-hospital stay. In conclusion, spinal cord and peripheral nerve involvement by Cryptococcus is an infrequent cause of acute flaccid paralysis that should be considered in the differential diagnosis even in HIV-negative patients.
Insights
Cryptococcal meningitis, a fungal infection, can cause rare cases of acute flaccid paralysis and peripheral nerve issues, even in non-HIV patients. Early diagnosis and antifungal treatment are crucial for recovery.
Area of Science:
- Neurology
- Infectious Diseases
- Mycology
Background:
- Cryptococcus is a fungus known for nervous system infections, particularly in immunocompromised individuals.
- Neurological cryptococcosis typically presents as meningitis with headache, fever, and neck stiffness, often affecting the brain.
Observation:
- A rare case of a non-HIV, diabetic patient presenting with acute flaccid paralysis and peripheral nerve involvement is described.
- The patient exhibited symptoms including dysarthria, facial paralysis, ascending quadriparesis, hyporeflexia, and urinary retention.
- Initial neuroimaging was inconclusive for vascular or demyelinating causes, and electrophysiological studies suggested acute flaccid paralysis of unknown origin.
Findings:
- Cerebrospinal fluid analysis confirmed Cryptococcus neoformans var. gatti as the causative agent.
- The patient received antifungal treatment with amphotericin B and fluconazole.
- Significant improvement in polyneuroradiculopathy symptoms was observed during hospitalization.
Implications:
- This case highlights that spinal cord and peripheral nerve involvement by Cryptococcus can manifest as acute flaccid paralysis.
- Cryptococcal meningitis should be considered in the differential diagnosis of acute flaccid paralysis, even in HIV-negative individuals.
- Prompt diagnosis and appropriate antifungal therapy are essential for managing this rare neurological complication.
