The differentialĭiagnosis will depend primarily on the anatomic location. Pelvic mass in a patient who is imaged for abdominal fullness or pain. The typical scenario is the discovery of a large abdominal or The presenting clinical manifestations and often the imaging findings of soft-tissue GIST gastrointestinal stromal tumor is also an important tumor for radiologists to recognize andĭifferentiate from other intra-abdominal and gastrointestinal malignancies because of Most important changes in the updated WHO World Health Organization classification ( Table 1) GIST gastrointestinal stromal tumor is included in this discussion because of its inclusion in the 2013 WHO World Health Organization classification of soft-tissue sarcomas this inclusion was one of the Stromal tumor (GIST gastrointestinal stromal tumor) is the most common gastrointestinal and intraperitoneal sarcoma.

In part 1 of this article, the most common soft-tissue Soft-tissue sarcomas, the anatomic locations where they occur, and theirĬross-sectional imaging features helps the radiologist establish the diagnosis orĭifferential diagnosis so that patients with soft-tissue sarcomas can receive optimal Knowledge of the classification and pathologic features of Any soft-tissue sarcoma can arise in theĪbdominal wall.
