Myxoinflammatory Fibroblastic Sarcoma: MR Appearance and Pathologic Correlation

The purpose of our study was to define the MR appearance of myxoinflammatory fibroblastic sarcoma of the soft tissues and to make correlations with the histopathologic features. Myxoinflammatory fibroblastic sarcoma is an uncommon malignancy that typically affects adult subjects, who present with painless swelling. This lesion manifests on MR images as a poorly circumscribed mass involving the underlying tendon sheath in the distal extremities.
