Purpose: To describe a patient with mesenchymal chondrosarcoma of the orbit, review clinical, imaging and pathologic findings as well as treatment modalities. Case Report: A 59-year-old woman presented with a 2-month history of progressive proptosis. CT revealed a clearly outlined heterogeneous mass with calcified foci, whereas MRI showed an isointense signal to gray matter on T1 and T2-weighted images with gadolinium enhancement. Tumor excision was performed via lateral orbitotomy and pathologic examination showed mesenchymal chondrosarcoma of the orbit. After surgery, radiotherapy and exentration were suggested to the patient, she refused the recommendations due to good visual acuity. After 10 months of follow up there was no local recurrence or metastasis in examinatons. Conclusion: When we encounter calcified tumor, the orbit mesenchymal chondrosarcoma must be considered in differential diagnosis.
