Soft-tissue lesions: when can we exclude sarcoma?

OBJECTIVE: A wide spectrum of space-occupying soft-tissue lesions may be discovered on MRI studies, either as incidental findings or as palpable or symptomatic masses. Characterization of a lesion as benign or indeterminate is the most important step toward optimal treatment and avoidance of unnecessary biopsy or surgical intervention. CONCLUSION: The systemic MRI interpretation approach presented in this article enables the identification of cases in which sarcoma can be excluded.
