Insights
Primary intracranial sarcoma, a rare pediatric brain tumor, often shows contrast enhancement, diffusion restriction, and hemorrhage on MRI scans. These imaging features can help in diagnosis.
Area of Science:
- Pediatric neuro-oncology
- Neuroradiology
- Oncologic imaging
Background:
- Primary intracranial sarcoma is a rare, high-grade malignant brain tumor.
- Limited data exists on pediatric primary intracranial sarcoma, especially regarding imaging characteristics.
Approach:
- A cross-sectional descriptive observational study was conducted.
- MRI characteristics of 18 pediatric patients (aged 1-18 years) diagnosed with primary intracranial sarcoma between 2015 and 2021 were reviewed.
Key Points:
- 100% of cases showed contrast enhancement.
- Diffusion restriction (78%), hemorrhage (89%), meningeal extension (67%), and necrosis (67%) were common findings.
- The majority (72%) of tumors were supratentorial.
Conclusions:
- Primary intracranial sarcomas are typically supratentorial.
- MRI findings in pediatric primary intracranial sarcoma resemble those of other intracranial malignancies.
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.
