Abstract:
Severely immunocompromised patients such as those with haematological malignancies and haematopoietic stem cell transplant recipients are at an increased risk of acquiring invasive mould infections. Fusarium, a ubiquitous fungus, can cause potentially fatal infections in such hosts. It usually manifests as skin lesions, fevers and sino-pulmonary infections. Brain abscesses have been reported, but are relatively uncommon. We report a case of a 50-year-old patient with acute lymphocytic leukaemia and failed autologous peripheral stem cell transplant that presented with new onset seizures and was found to have Fusarium solani brain abscess. Nasal route was the presumed mode of entry of the fungus into the cerebrum. Treatment comprised surgical excision of the lesion, and antimycotic therapy with liposomal amphotericin B and voriconazole. Despite aggressive therapy, patient succumbed to the disease. We have provided an overview of infections secondary to Fusarium, along with a review of the central nervous system involvement by this pathogenic mould.
Insights
Fusarium solani can cause rare but fatal brain abscesses in immunocompromised patients, particularly those with leukaemia. Despite aggressive treatment including surgery and antifungals, the patient in this case succumbed to the infection.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Neuroscience
Background:
- Severely immunocompromised individuals, including those with hematological malignancies and hematopoietic stem cell transplant recipients, face a heightened risk of invasive fungal infections.
- Fusarium species, ubiquitous fungi, pose a significant threat, causing potentially fatal infections in these vulnerable populations.
Observation:
- A 50-year-old patient with acute lymphocytic leukemia and a history of failed autologous peripheral stem cell transplant presented with new-onset seizures.
- Diagnostic imaging revealed a brain abscess caused by Fusarium solani, with the nasal route presumed as the entry point into the cerebrum.
Findings:
- The case highlights the uncommon but severe neurological complication of Fusarium infection in immunocompromised hosts.
- Treatment involved surgical excision of the brain abscess and a combination of antifungal therapies, including liposomal amphotericin B and voriconazole.
Implications:
- This case underscores the critical need for prompt diagnosis and aggressive management of invasive Fusarium infections in immunocompromised patients.
- Further research into the pathogenesis and treatment strategies for central nervous system Fusarium infections is warranted to improve patient outcomes.
