Abstract
A kidney transplant recipient with mucormycosis in the nose and paranasal sinuses which had occurred during a treatment by immunosuppressive agents is reported. Mucormycosis in this case was the type of nose-brain-eye and invaded the intra-cranial region rapidly. However, it was difficult to diagnose because of normal findings in X-ray study of the nose and skull before surgery, but MRI was one of suitable methods for diagnosis of the case. Usefulness of MRI for an early diagnosis of this disease should be confirmed in future. When some symptoms in the nose and/or eye appear in a patient with immunodeficiency we should pay attentions to this disease.
