Primary sarcomas of the central nervous system are rare. These tumors is rapid growth often produces mass effect on the brain. Diagnosis is rendered pathologically after resection. Surgical resection is the mainstay treatment and need the adjuvant therapy. We report a 44-year-old female with a meningeal sarcoma of frontal meninges. She complained headache for 2 months and palpable forehead mass for 3 weeks. Brain MRI demonstrated a soft tissue mass sized as 5.3×3.7×3.1 cm with well-defined osteolysis on the midline of the frontal bone. The mass attached to anterior falx without infiltration into the brain parenchyme. The tumor had extracranial and extraaxial extension with bone destruction. The tumor was totally removed with craniectomy and she had an adjuvant radiotherapy. However, an isolated subcutaneous metastasis developed at the both preauricular area of the scalp, originating from the scar which was remained the first surgery. After complete removal of this metastasis, she had an adjuvant radiotherapy in other hospital. However, she expired after six months after first surgery. We believe that the occurrence of tumor seeding at the site of incision in the scalp is related to using the fluid for irrigation after tumor resection and the same surgical instruments for the removal of the brain tumor.
