Abstract:
A 51-year-old male was admitted in our institute following an episode of near-drowning. He later developed ventriculitis and cerebral ring-enhancing lesions. He died following a subarachnoid hemorrhage due to rupture of a mycotic aneurysm involving the right fetal posterior cerebral artery. Scedosporium apiospermum was isolated from the cerebrospinal fluid. Central nervous system invasion by S apiospermum may present insidiously in near-drowning patients and, therefore, requires a high index of suspicion. In cases with the characteristic cerebral ring-enhancing lesions and concomitant ventriculitis, treatment should be instituted while awaiting fungal culture. With this article we intend to alert neurologists, intensivists, and physicians to this near fatal infection, as early identification and prompt treatment with voriconazole may be life saving.
Insights
Near-drowning can lead to insidious Scedosporium apiospermum infections of the central nervous system, causing ventriculitis and ring-enhancing lesions. Prompt voriconazole treatment is crucial for survival.
Area of Science:
- Mycology
- Infectious Diseases
- Neurology
Background:
- Near-drowning incidents can precipitate serious medical complications.
- Fungal infections of the central nervous system (CNS) pose significant diagnostic and therapeutic challenges.
Observation:
- A 51-year-old male developed ventriculitis and cerebral ring-enhancing lesions after a near-drowning event.
- The patient experienced a fatal subarachnoid hemorrhage due to a ruptured mycotic aneurysm.
- Scedosporium apiospermum was identified in the cerebrospinal fluid.
Findings:
- Central nervous system invasion by Scedosporium apiospermum can present subtly in near-drowning survivors.
- Cerebral ring-enhancing lesions and ventriculitis are key indicators of this infection.
- Early initiation of antifungal therapy, even before definitive culture results, is critical.
Implications:
- Neurologists and intensivists must maintain a high index of suspicion for Scedosporium apiospermum in near-drowning patients with CNS symptoms.
- Prompt diagnosis and treatment with voriconazole can be life-saving.
- This case highlights the potential for rare fungal pathogens to cause severe neurological sequelae.
