title: Metastatic synovial sarcoma to the skull base and orbit.
abstract: OBJECTIVE
  To report a case of metastatic synovial sarcoma to the parasellar area and orbit.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 43-year-old woman with a history of a right forearm synovial sarcoma treated with excision, radiation, and chemotherapy 16 months previously presented with blurred vision of the right eye, pain with eye movement, epistaxis, and a right superior division cranial nerve III palsy. Magnetic resonance imaging showed a right parasellar and right orbital apex mass.
  
  
  RESULTS
  Pathologic examination of the parasellar biopsy revealed metastatic synovial sarcoma. At 6-month follow-up, the neuro-ophthalmic examination was unchanged, and repeat magnetic resonance imaging showed no recurrence of the tumor.
  
  
  CONCLUSIONS
  Metastatic synovial sarcoma should be added to the differential diagnosis of parasellar and orbital tumors.
