A Case of Chondromyxoid Fibroma in the Sphenoidal Sinus

抄録

Chondromyxoid fibroma is a rare cartilaginous tumor, accounting for only 1% of all bone tumors. In most cases, these tumors arise from the tubular bones, and cases of the tumor arising from the skull base are extremely rare.

In this paper, we report a case of chondromyxoid fibroma of the sphenoidal sinus. The patient was a 65-year-old woman who presented to us with a 1-year history of double vision. At first, based on the imaging findings, we suspected sinusitis with fungal infection of the sinus. Biopsy revealed chondromyxoid fibroma, and the patient was treated by radiotherapy. However, at present, 7 months after the treatment, the tumor remains unchanged, indicating the need for careful follow-up of the patient.
