Overview
MRI may be performed to detect metastases of epithelioid sarcoma and to determine anatomic boundaries.
Key Findings in Epithelioid sarcoma
- MRI is the diagnostic modality of choice for imaging prior to biopsy and pathologic diagnosis, with the primary role being the determination of anatomic boundaries.
- MRI helps to differentiate tumor recurrence from post-operative changes.[1]
- Findings include:
- On T2/fluid sequences, the mass is typically hyperintense with areas of central necrosis and surrounding edema.
- There is usually heterogeneous enhancement, often with areas of necrosis.
- A characteristic finding, is propagation along fascial planes, tendon sheaths and nerves.
