Resumen

Background: Primary intracranial sarcoma is a very rare high-grade tumor. Scant reports exist on this malignancy in children, which limit the information about its imaging characteristics. Objective: We aimed to describe the main characteristics of primary intracranial sarcoma on MRI. Materials and methods: In this cross-sectional descriptive observational study, we reviewed 18 patients (aged 1–18 years) with primary intracranial sarcomas diagnosed between 2015 and 2021. Results: The main findings were contrast enhancement (100%), diffusion restriction (78%), hemorrhage (89%), meningeal extension (67%), necrosis (67%), and supratentorial location (72%). Conclusion: Primary intracranial sarcoma are typically supratentorial in location. MRI findings of primary intracranial sarcoma are similar to other intracranial malignancies.
