Presentation
Patient presented with left thigh painless swelling that increased over the last month. No history of previous trauma. No signs of inflammation.
Patient Data
Different MRI planes and pulse sequences without and with IV contrast of the left thigh showed a well-defined oval-shaped lesion located medial to the superficial part of the vastus medialis muscle and posterior to the sartorius muscle, eliciting a low T1 and high T2 signal with avid contrast enhancement measuring about 7.5 x 6.3 x 4 cm and no abnormal signal in the adjacent femur.
Case Discussion
Extraskeletal Ewing sarcoma is a relatively uncommon primary tumor of the soft tissues. Magnetic resonance imaging is the modality of choice for diagnostic imaging and local staging, while core-needle biopsy with pathological testing is used to obtain a definitive diagnosis.
