Summary
Extraosseous Ewing's sarcoma rarely occurs in the brain, often mimicking meningioma on imaging. Early recognition is crucial, especially in young patients with solitary dural-based lesions.
Area of Science:
- Neuro-oncology
- Skeletal system oncology
Background:
- Extraosseous Ewing's sarcoma (EES) commonly affects the extremities, paravertebral, and retroperitoneal regions.
- Primary intracranial EES is rare and typically presents as an intraparenchymal tumor when supratentorial.
Observation:
- A case of a 20-year-old male presenting with neurological symptoms is described.
- Radiographic imaging revealed an epidural lesion mimicking a meningioma.
- Histopathological diagnosis confirmed the lesion as Ewing's sarcoma.
Findings:
- Intracranial extraosseous Ewing's sarcoma can present as an extra-axial epidural tumor.
- This rare presentation can radiographically mimic a meningioma.
Implications:
- Physicians should consider EES in the differential diagnosis of solitary, contrast-enhancing, dural-based lesions in young individuals.
- Awareness of this rare mimicry is vital for accurate diagnosis and timely treatment of intracranial Ewing's sarcoma.
