Abstract

A 55-year-old man was diagnosed with gastric adenocarcinoma. 18F-FDG PET/CT was performed, which detected an enlarged nodule with increased uptake located in the omentum between the transverse colon and liver, thus lymph node metastasis was under suspicion. The patient subsequently underwent 68Ga-FAPI PET/MRI clinical trial after signing the informed consent, which also revealed the abnormal focus with intense uptake. However, the histopathology of the nodule was unexpectedly diagnosed as fibrous hyperplasia after lymphadenectomy.

摘要

一位 55 岁男性被诊断为胃腺癌。进行了 18F-FDG PET/CT 检查，发现横结肠和肝脏之间的网膜上有一个增大的结节，摄取增加，因此怀疑淋巴结转移。患者在签署知情同意书后，随后进行了 68Ga-FAPI PET/MRI 临床试验，结果也显示异常焦点摄取明显增加。然而，淋巴结切除术后，该结节的组织病理学诊断出乎意料地为纤维增生。
