Summary
Primary meningeal sarcomas are rare, aggressive pediatric brain tumors. Early biopsy is crucial for diagnosis and treatment, as imaging alone is often insufficient.
Area of Science:
- Pediatric Oncology
- Neuro-oncology
- Pathology
Background:
- Primary meningeal sarcomas are rare and aggressive pediatric tumors.
- This study reviews two pediatric cases, discussing clinical, imaging, and histopathological features.
- It also examines the latest WHO classification of these rare tumors.
Observation:
- A 6-year-old girl presented with hemorrhage after head trauma, later developing a meningeal mass. A biopsy revealed polymorphocellular sarcoma.
- An 8-year-old girl experienced headaches and vomiting; MRI initially showed no abnormalities, but later revealed diffuse leptomeningeal enhancement, diagnosed as leptomeningeal sarcomatosis.
Findings:
- Computed tomography (CT) and magnetic resonance imaging (MRI) visualized tumor extent but lacked diagnostic specificity.
- Histopathological examination via brain biopsy was essential for definitive diagnosis in both cases.
- No specific imaging criteria exist to differentiate meningeal sarcoma from other brain tumors or meningeal diseases.
Implications:
- Early open brain biopsy or surgical resection is vital to prevent misdiagnosis and treatment delays for unclear brain masses.
- Accurate diagnosis of meningeal sarcoma requires histopathological confirmation.
- Further research is needed to understand the biological behavior and optimal clinical management of this rare tumor entity.
