MRI findings of primary intracranial sarcomas in children.

Abstract

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. We aimed to describe the main characteristics of primary intracranial sarcoma on MRI. In this cross-sectional descriptive observational study, we reviewed 18 patients (aged 1-18years) with primary intracranial sarcomas diagnosed between 2015 and 2021. The main findings were contrast enhancement (100%), diffusion restriction (78%), hemorrhage (89%), meningeal extension (67%), necrosis (67%), and supratentorial location (72%). Primary intracranial sarcoma are typically supratentorial in location. MRI findings of primary intracranial sarcoma are similar to other intracranial malignancies.
