title: The Radiologic Features of Non-Neoplastic Tumors of Soft Tissue.
abstract: Neoplasms of the soft tissues cause localized swelling and a variable degree of tissue response on the part of the host; these features they share with many non-neoplastic disorders. A spectrum of lesions that may simulate soft tissue neoplasms are described, with their radiologic appearances. The cellular nature of the matrix of a lesion cannot be identified absolutely as neoplastic by current imaging methods. Although sonography and magnetic resonance imaging can each produce valuable diagnostic information hitherto not provided by imaging the soft tissues, they do not per se show evidence of neoplasia. The differentiation of the two types of tumor, neoplastic and non-neoplastic, can only be achieved by a combination of clinical, radiologic and histologic information. Ultimately, biopsy with histologic examination may be required for the definitive diagnosis.
