对42例经组织病理学确诊的胃肠道间质瘤（GIST）的影像学特征进行分析，观察其转移规律。就诊时，42 名患者中有 22 名 (52.3%) 显示转移。在随访过程中，另外三例病例在切除后一年内出现转移。肠系膜、大网膜和肝脏是最常见的转移部位。其他很少被报道涉及的部位由于生存时间较长而越来越多地被认为显示出转移。转移灶常表现出与原发性GIST类似的衰减和强化特征，并常表现为坏死、出血和钙化。
The imaging features of 42 histopathologically confirmed cases of Gastrointestinal Stromal Tumors (GIST) were analyzed, to observe the pattern of metastasis. At presentation 22 of 42 patients (52.3%) showed metastasis. During follow-up, three more cases developed metastasis, within one year of resection. Mesentery, omentum, and liver were the most frequent sites for metastasis. Other sites that were rarely reported to be involved were increasingly recognized to show metastasis due to longer survival. The metastasis often showed attenuation and enhancement characteristics, similar to primary GIST, and frequently showed necrosis, hemorrhage, and calcification.
