Combination endoscopic surgical debridement and transcutaneous retrobulbar amphotericin B for acute rhino-orbital-cerebral aspergillosis

PURPOSE: To report a case of acute rhino-orbital-cerebral aspergillosis with aggressive intracranial and orbital extension co-managed medically and surgically with endoscopic sinus debridement and multiple retrobulbar injections of amphotericin B. OBSERVATIONS: A 70-year-old male patient presented via external transfer with headaches and left ophthalmoplegia concerning for severe complicated sinusitis with intracranial and left orbital spread. His history is notable for a simultaneous heart-kidney transplant three years prior on chronic immunosuppression. Ophthalmologic examination revealed complete ophthalmoplegia in the left eye with no light perception concerning for a left orbital apex syndrome. The patient was taken to the operating room twice for endoscopic sinus debridement and three separate retrobulbar injections of amphotericin B. Fungal cultures from surgical specimens grew isolated Aspergillus fumigatus. Patient's symptoms gradually improved and repeat MRI demonstrated resolution of pansinusitis, sparing left eye exenteration. CONCLUSIONS AND IMPORTANCE: Multidisciplinary management of invasive fungal rhinosinusitis in the setting of profound immunosuppression poses a significant challenge. While surgical debridement remains the cornerstone approach, the achievable reduction in disease burden may be augmented by targeted retrobulbar antimicrobials.
