Multiple myeloma is a systemic disease with neoplastic proliferation of plasma cells. Cavernous sinus involvement is rare in multiple myeloma. The role of imaging with MRI to exclusion of involvement is great because the cavernous sinus can be evaluated very well by magnetic resonance imaging (MRI). Our case, a seventy seven-year-old female patient, applied to our policlinic with visual disturbance in the left eye. In the neurological examination of the patient; the left eye was inside in the primary position, bilateral external vision limitation was present marked in the left eye and downward vision limitation was present in the left eye. Patient's brain MRI showed patchy and nodal signals in the frontoparietal lob borderzone area may be compatible with heart attack and causing asymmetric enhancement of the left cavernous sinus and expanding soft tissue lesion was detected. The patient was evaluated as multiple myeloma-associated left cavernous sinus involvement and the patient was directed to the oncologic treatment center to re-evaluate any oncologic therapy. Since cavernous sinus involvement is rare in multiple myeloma, we found this patient worthy to present.
