Refractory rhino-orbito-cerebral mucormycosis treated with intraconal amphotericin B

We report the case of a 46-year-old diabetic man receiving treatment for rhino-orbital-cerebral mucormycosis with liposomal amphotericin B and surgical debridement. The patient's condition worsened clinically, accompanied by the loss of ocular motility and a visual acuity of absence of light perception. Radiological extension of the infection was evidenced, with invasion of the cavernous sinus. Based on ophthalmological findings, exenteration (a potentially disfiguring procedure) was indicated, but we opted for wide surgical debridement and administration of amphotericin B via intraconal catheter. Clinical improvement and resolution of inflammation occurred after 2 weeks of treatment. Thus, rhino-orbital-cerebral mucormycosis was effectively controlled through intraconal administration of amphotericin B, while avoiding exenteration. The intervention should be considered as an adjuvant treatment in selected rhino-orbital-cerebral mucormycosis cases before attempting exenteration.
