Bilateral cellulitis caused by invasive aspergillosis associated with bilateral intraorbital abscesses: a case report

Background Orbital invasive aspergillosis infection is rare life-threatening infection, most commonly seen in immunocompromised patients and extremely rare in individuals without risk factors. Here we present a rare case of bilateral cellulitis caused by invasive aspergillosis associated with bilateral intraorbital abscesses in a female patient. Case presentation A 49-year-old woman presented with a 3-month history of painful proptosis and periorbital swelling of bilateral eyes. She was initially diagnosed as bilateral orbital cellulitis complicated with cavernous sinus thrombosis and was treated with antibiotic medication for 1 month, but her symptoms persisted. MRI demonstrated orbital masses behind both globes. The lesion in right orbit was biopsied with a diagnosis of orbital granulomatosis with invasive aspergillosis infection. The patient was healed after receiving antifungal treatment. Conclusions This is an unusual case about bilateral orbital abscesses with invasive fungal infection. Fungal infection of the orbit should be considered when patient does not respond to combination of anti-inflammatory and antibiotic therapies, even in some cases without any risk factors.
