Introduction
Synovial sarcoma is the fourth most common sarcoma of the soft
tissue,following liposarcoma,fibrous histiocytoma and
rhabdomyosarcoma.With more prevelance in men than women.Most of the SS
cases are located in extrimities,predominantly lower extremites(1, 2).
especially near large joints around the knee and thigh(3). Synovial
sarcoma has an annual incidence of 2.5 per 100,000(4). Intracranial
synovial sarcoma is very uncommom and has been reported as a metastasis
lesion from synovial sarcoma in other parts of the body (3, 5-11).In
this study, We report a case with no obvious primary extracranial
pathology, with recurrent primary intracranial synovial sarcoma,which
has been very rarely reported in literature.
