Cranial nerve palsy: an unusual presentation of a fulminant fungal disease.

Mucormycosis is a rare and dramatic fungal disease with a high mortality rate. We report a case of rhino- orbital mucormycosis, which commenced as cranial nerve palsy, in a woman with ignored diabetes mellitus. Mucormycosis should therefore be taken into consideration during the differential diagnosis of cranial nerve palsy, especially in diabetic or immunocompromised patients.
