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.
