Summary
Invasive sinus aspergillosis can be fatal in immunocompetent individuals. Early diagnosis and aggressive surgical resection are crucial for successful treatment of this serious fungal infection.
Area of Science:
- Infectious Diseases
- Mycology
- Otolaryngology
Background:
- Invasive sinus aspergillosis (ISA) is a severe fungal infection.
- While often associated with immunocompromised patients, ISA can affect immunocompetent hosts.
Observation:
- This study reviewed 29 cases of ISA in immunocompetent patients, including three new cases.
- Presenting symptoms and CT findings were non-specific, often delaying diagnosis.
- Histopathology and culture of sinus biopsies had limited diagnostic yield.
Findings:
- Fifty-nine percent of patients experienced treatment failure or mortality.
- Risk factors for poor prognosis included delayed diagnosis, intracranial extension, and vascular invasion.
- Complete surgical extirpation was the most critical factor for successful treatment, with antifungals playing a secondary role.
Implications:
- ISA carries a high risk of morbidity and mortality, even in immunocompetent individuals.
- Early recognition and aggressive surgical management are vital to prevent central nervous system or vascular invasion.
- Timely diagnosis and intervention can improve patient outcomes for this challenging infection.
