UNLABELLED

Liver metastases from neuroendocrine tumours frequently occur and significantly worsen their prognosis. Somatostatin receptor scintigraphy (SRS) is a valuable method for the detection of somatostatin receptor-positive lesions like gastrinoma. In this case report, the importance of SRS to localize the primary tumor and the spread of disease is emphasized in a patient with neuroendocrine liver metastases. A 45-year-old man was admitted to hospital with multiple liver metastasis of neuroendocrine carcinoma. Somatostatin receptor scintigraphy showed multiple intense radiotracer uptakes in the liver and a focal tracer uptake at the right side of the upper abdominal region corresponding to duodenum or pancreas. Elevated serum gastrin levels confirmed the gastrinoma diagnosis.

神经内分泌肿瘤的肝转移很常见，且会显著恶化其预后。生长抑素受体闪烁扫描术（SRS）是检测生长抑素受体阳性病变（如胃泌素瘤）的一种有价值的方法。在本病例报告中，强调了SRS对一名神经内分泌肝转移患者定位原发性肿瘤和疾病扩散的重要性。一名45岁男性因神经内分泌癌多发肝转移入院。生长抑素受体闪烁扫描术显示肝脏有多个放射性示踪剂浓聚摄取点，上腹部右侧对应十二指肠或胰腺处有一个局灶性示踪剂摄取点。血清胃泌素水平升高证实了胃泌素瘤的诊断。
