胃肠道间质瘤(GIST)的特点是其分化潜能具有显著的差异性，但这些病变大多没有显示令人信服的平滑肌或神经元分化。起源于直肠或肛管的胃肠道间质瘤极为罕见。我们提出一例免疫组织化学证实的直肠GIST病例，在T2加权像上表现为均匀等信号的肿块，没有坏死或出血，在Gd增强扫描上有强化。
Gastrointestinal stromal tumors (GISTs) are characterized by remarkable variability in their differentiation potential, but most of these lesions do not display convincing smooth muscle or neuronal differentiation. The GISTs arising from the rectum or anal canal are extremely uncommon. We present a case of immunohistochemically proven GIST of the rectum, which was characterized by homogenous isointensity mass without necrosis or hemorrhage on T2-weighted image and by enhancement on gadolinium-enhanced study.
