A Case of Chronic Invasive Fungal Sinusitis With Orbital Abscess

This case report describes a male patient with chronic invasive fungal sinusitis, mainly characterised by swelling of the eye. After a definitive diagnosis was made based on clinical symptoms and imaging studies, the patient received timely antimicrobial and symptomatic treatment, followed by functional endoscopic sinus surgery and orbital abscess drainage. The foci of infection in the sinuses were completely removed and adequate drainage of the sinuses was achieved, resulting in significant relief of the patient's symptoms. The follow-up examination 1 month after discharge showed a good recovery.
