We present the case of a 44-year-old woman with chondromyxoid fibroma of temporal bone origin. Since this is the least common bone tumor of cartilaginous origin, it is highly unusual to find this tumor in the skull. In fact, the literature describes 18 cases of this form of neoplasia arising in the skull, only 4 of these having originated in the temporal bone. To date, the radiological features of these tumors, and especially features detected using the latest imaging modalities, have not been described in detail. This report is unique in that it is the first to present a case of chondromyxoid fibroma of the temporal bone accompanied by detailed CT and MRI findings.

Rheumatoid arthritis is a systemic disease in which cerebral and eye involvement is neither common nor fully understood. Although it is rarely the cause of pachymeningitis and optic neuritis, rheumatoid arthritis should always be kept in mind in these two conditions. We present a 52-year-old male with an 8 month history of rheumatoid arthritis who was referred to the neurology department with headache and decreasing vision and was diagnosed as having rheumatoid pachymeningitis and optic neuritis on the basis of MRI findings.
