A gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. The tumor originates from Cajal cells, which generated peristaltic motion. Primary gastrointestinal stromal tumor of the liver is rare and should be considered in imaging diagnosis. We report a case of an 82-year-old female patient who represented with upper abdominal pain and poor appetite. Magnetic resonance imaging detected a large left lobe cystic lesion (10 × 15 cm). The tumor was resected. The histopathological and immunohistochemical results were of a primary gastrointestinal stromal tumor in the liver with cystic changes. On imaging, it is difficult to differentiate from other cystic lesions.
胃肠道间质瘤（GIST）是胃肠道最常见的间叶组织肿瘤。该肿瘤起源于产生蠕动的 Cajal 细胞。原发性肝脏胃肠道间质瘤罕见，在影像诊断中应予以考虑。我们报告一例 82 岁女性患者，表现为上腹部疼痛和食欲不佳。磁共振成像检测到左叶有一个大的囊性病变（10×15 厘米）。肿瘤被切除。组织病理学和免疫组化结果显示为肝脏原发性胃肠道间质瘤伴囊性变。在影像学上，它很难与其他囊性病变相鉴别。
