Invasive fungal sinusitis by Scedosporium boydii in an immunocompromised patient. A case report.

Invasive fungal sinusitis by Scedosporium spp. is a rare but severe infection in immunocompromised patients. We report an 80-year-old woman with poorly controlled diabetes and chronic corticosteroid use who presented with headache, hearing loss, and facial paralysis. She was ultimately diagnosed with sphenoid sinusitis due to Scedosporium boydii. Management required surgical debridement and prolonged antifungal therapy complicated by drug-induced liver injury. Early diagnosis and multidisciplinary treatment are crucial to improve prognosis in these complex infections.
