Summary
Extraskeletal Ewing's sarcoma rarely occurs in the neck, often infiltrating through neural foramina. Diagnosis relies on advanced imaging like CT and MRI, alongside histology, for effective management.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Extraskeletal Ewing's sarcoma (EES) is a rare mesenchymal tumor, histologically similar to its osseous counterpart.
- While commonly found in the lower limb and paravertebral regions, EES in the neck is exceptionally rare.
Observation:
- This case highlights EES presenting as a right-sided neck mass with vocal fold palsy and T1 nerve root involvement.
- Imaging revealed tumor infiltration through neural exit foramina of cervical nerve roots and vertebral artery encasement.
Findings:
- Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated characteristic features crucial for diagnosis.
- Histological analysis confirmed the diagnosis of extraskeletal Ewing's sarcoma.
Implications:
- EES has a predilection for paravertebral locations and can infiltrate neural exit foramina, even in the rare cervical presentation.
- CT and MRI are vital diagnostic tools for this rare tumor, guiding treatment strategies including chemotherapy and irradiation.
