Gastrointestinal stromal tumors (GISTs) originate from the gastrointestinal tract. GISTs originate outside the gastrointestinal tract, referred to as extra GISTs, which is rare. Primary liver gastrointestinal stromal tumor (PLGIST) and liver metastasis of gastrointestinal stromal tumor (LMGIST) may present isolated liver lesion, making it difficult to determine their origin. A 38-year-old man who presented with isolated multiple giant cystic-solid liver lesions, ultimately diagnosed as liver GIST through CT-guided fine-needle aspiration. However, distinguishing between PLGIST and LMGIST in this case is challenging due to the absence of detailed medical records of emergency small intestine resection 5 years ago. Over 2-year follow-up period, the maximum lesion size increased from 16 to 21 cm, still, no extra liver lesions were observed. This study aims to provide a review to enhance understanding of this rare liver entity, aiding in tumor diagnosis and staging.
胃肠道间质瘤（GISTs）起源于胃肠道。起源于胃肠道外的 GIST 被称为外 GIST，较为罕见。原发性肝脏胃肠道间质瘤（PLGIST）和胃肠道间质瘤肝转移（LMGIST）可表现为孤立性肝脏病变，难以确定其来源。一位 38 岁男性，表现为孤立性多发巨大囊实性肝脏病变，最终通过 CT 引导下细针穿刺诊断为肝脏 GIST。然而，由于 5 年前急诊小肠切除术的详细病历缺失，区分 PLGIST 和 LMGIST 存在一定的挑战。在超过 2 年的随访期间，最大病变从 16cm 增大到 21cm，但未观察到其他肝脏病变。本研究旨在提供一个综述，以增强对这种罕见肝脏实体的认识，有助于肿瘤的诊断和分期。
