We present a case of duodenal leiomyosarcoma studied with computerized tomographic (CT) and magnetic resonance (MR) images. Some differential diagnostic remarks are mentioned. The topographic abilities of MR to determine the exact origin of the tumor are stressed. A stellar "scar", hypointense on T1 and hyperintense on T2-weighted images (1 Tesla) in association with gastrointestinal leiomyosarcoma was, at least to the best of our knowledge, never mentioned before in the literature.
我们报告一例经计算机断层扫描（CT）和磁共振（MR）成像研究的十二指肠平滑肌肉瘤病例。文中提及了一些鉴别诊断要点。强调了MR在确定肿瘤确切起源方面的定位能力。据我们所知，与胃肠道平滑肌肉瘤相关的一种星状“瘢痕”，在T1加权像上呈低信号、在T2加权像（1特斯拉）上呈高信号，此前在文献中从未被提及。
