A Case of Ethmoid Fibrous Dysplasia

A 36-year-old male with ethmoid fibrous dysplasia is reported. The tumor-like lesion was detected by chance with a CT scan when the patient was ill with a transient cerebral ischemic attack. The expansive tumor of the right ethmoid sinus was a non-homogenous high density image in the CT scan. Extirpation of the tumor-like lesion was performed by the extended Denker's method, revealing the red brown sherbet-like lesion. It was pathologically diagnosed as fibrous dysplasia.
