Abstract/OtherAbstract:
Gastrointestinal stromal tumors (GIST) represent an extremely rare group of tumors, which are mostly of smooth muscle origin like leiomyomas, leiomyosarcomas and leiomyoblastomas. With the introduction of immunohistochemical analysis an epithelioid and an autonomic nerve variant can be distinguished. The purpose of this review is to demonstrate the image morphological appearance of these rare tumors together with the pathology based upon a retrospective analysis of five of our own cases since 1997. There are no pathognomonic imaging findings for characterizing a gastrointestinal stromal tumor; however, it should be included in the differential diagnosis if one or multiple large, round or oval, well-delineated gastrointestinal tumors occur in combination with central necrosis. Carney's syndrome is characterized by the syndromal association of a gastrointestinal stromal tumor (originally: gastric leiomyosarcoma) with an extra-adrenal paraganglioma and a pulmonary chondroma. In this rare syndrome, the radiological approach is important to diagnose or rule out the--simultaneous or consecutive--appearance of at least two of the three tumor entities (GIST, extra-adrenal paraganglioma, pulmonary chondroma).
