Cryptococcus myelitis: atypical presentation of a common infection
1Department of Medicine, University of Zimbabwe Medical School, Harare, Zimbabwe. hutachiona@netscape.net
Abstract:
Cryptococcus neoformans is associated with as much as 45% of meningitis in patients admitted for hospital care in Zimbabwe, and it is an important opportunistic infection in patients infected with the human immunodeficiency virus. Cases of cryptococcosis presenting as a spinal cord syndrome have been reported from Zimbabwe and South Africa, but these were all cases of Cryptococcus vertebral osteomyelitis. We describe 3 unusual patients who presented with a myelitis-like syndrome without vertebral osteomyelitis.
Insights
Cryptococcus neoformans causes significant meningitis in Zimbabwe, especially in HIV patients. This study details three rare cases of myelitis-like syndromes caused by this fungus, without vertebral bone infection.
Area of Science:
- Infectious Diseases
- Neurology
- Mycology
Background:
- Cryptococcus neoformans is a major cause of meningitis, particularly in individuals with human immunodeficiency virus (HIV).
- In Southern Africa, cryptococcosis has been linked to spinal cord syndromes, typically due to vertebral osteomyelitis.
- The prevalence of cryptococcal meningitis in Zimbabwean hospitals reaches up to 45%.
Observation:
- Three patients presented with a myelitis-like syndrome.
- These patients did not exhibit signs of Cryptococcus vertebral osteomyelitis.
- The clinical presentation mimicked other causes of myelitis.
Findings:
- The study identifies unusual presentations of cryptococcosis.
- It highlights the potential for Cryptococcus neoformans to cause myelitis without vertebral involvement.
- Diagnostic challenges in differentiating fungal myelitis from other causes are implied.
Implications:
- This expands the spectrum of neurological complications associated with Cryptococcus neoformans.
- It suggests a need for heightened awareness and consideration of fungal infections in myelitis cases, even without bone lesions.
- Further research into the pathogenesis and diagnostic approaches for non-osteomyelitic spinal cryptococcosis is warranted.
