Background: Primary intracranial sarcoma is a rare disease. Due to the scarcity of evidence from randomized clinical trials, we follow the treatment guidelines of their extracranial counterparts or those published in case reports, while taking into consideration the specificity of radiotherapy within the brain, and the limit imposed on chemotherapy by the blood brain barrier. Nevertheless, surgery remains the golden standard of treatment for primary tumours, and also for recurrence. Even though there are usually narrow margins achieved in brain compared with the extracranial sarcomas. Despite significant effort, prognosis remains dismal. Case: We present a 69-year old woman who was investigated for psychoorganic syndrome and paresis of the left hand. Magnetic resonance imaging revealed a tumour expansion in her frontal lobe with collateral oedema. Surgical resection was indicated. Histology of the specimen suggested a myxoid meningeal sarcoma. Early disease recurrence 4 months after primary resection was treated by reresection and 50 Gy of adjuvant radiotherapy to the tumour bed. Similarly, another recurrence 19 months after the second surgery was treated using the same approach. Systemic treatment has not been indicated so far. At this time, the patient is without evidence of any disease recurrence and continues with regular follow-up. Conclusion: Myxoid meningeal sarcoma represents a rare disease with a high risk of recurrence. Unfortunately, there is no clear recommendation for treatment algorithm.
