MRI findings of primary intracranial sarcomas in children

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.
