Leiomyosarcoma of the stomach is a rare occurrence, amounting to only 0.5-3% of all stomach malignancies. Because of its extragastral growth, it produce clinical symptoms, mostly with bleeding, only at a late stage. The decisive method of examination is computed tomography which demonstrates the extraluminal tumor lying apparently in the mesenterium with contrast medium up-take at the borders and central necrosis. A secure differential diagnosis to leiomyoma is not possible by angiography or by computed tomography; this distinction is even difficult by histology.
胃平滑肌肉瘤是一种罕见的疾病，仅占所有胃恶性肿瘤的0.5%-3%。由于其向胃外生长，它仅在晚期才产生临床症状，主要是出血。决定性的检查方法是计算机断层扫描，它显示出位于肠系膜中的腔外肿瘤，边界有造影剂摄取且中央坏死。通过血管造影或计算机断层扫描无法对平滑肌瘤进行可靠的鉴别诊断；即使通过组织学进行这种区分也很困难。
