Rhino-cerebral fungal infections are rare and difficult disorders to cure. We report the case of a woman presenting a left trigeminal neuralgia complicated by ophthalmoplegia and blindness. MRI demonstrated a lesion of the left orbital apex with extension into the cavernous sinus. Fungal infiltration (aspergillosis or mucormycosis), was seen on biopsy. High-dose liposomal Amphotericin B (5mg/kg/day) for six weeks was unsuccessful. Adjunctant hyperbaric oxygen therapy led to clinical and radiological improvement. Hyperbaric oxygen therapy is discussed in the medical management of rhino-cerebral yeast abscesses.
