We report an autopsy case of 53-year-old male with poor controlled diabetes mellitus and hepatocellular carcinoma who developed rhino-orbito- cerebral mucormycosis. Initial complaints were epistaxis and headache followed by a sudden blindness, the 2nd through 7th cranial nerve palsy and diabetes insipidus. Laboratory data revealed that he had liver cirrhosis due to hepatitis C virus infection and diabetes mellitus. Head CT and MRI showed no significant findings. Eleven days after the onset, he died of subarachnoid hemorrhage. The postmortem examination revealed severe infiltration of numerous mucors in the sphenoid sinus, cavernous sinus and bilateral internal carotid arteries. Severe granulomatous vasculitis was seen in the cavernous portion of the bilateral internal carotid arteries. Thus, we considered that this case had been caused by the infiltration of mucors to the cavernous sinus, resulting in the obstruction of ophthalmic arteries. Rupture of the right internal carotid artery was seen at the branching portion of the ophthalmic artery, demonstrating the cause of his death. We would like to emphasize that rhino-orbito-cerebral mucormycosis should be ruled out if we examine a nondiagnostic case of diabetes mellitus or immunosuppressed disease associated with rapid multiple cranial nerve palsy following the orbital symptoms.
