转移性乳腺癌的原发灶主要见于淋巴瘤和黑色素瘤,而胃癌转移至乳腺的发生率仅为0.5%~1.2%[1-2]。原发性胃癌仅伴乳腺及腋窝淋巴结转移在临床中罕见,且18F-FDG PET/CT影像学征象不典型,在临床中容易误诊。我们报道了1例胃腺癌乳腺转移18F-FDG PET/CT显像的病例,从临床表现、18F-FDG PET/CT影像学表现、病理诊断及鉴别诊断等方面分析了该病的特点,旨在拓宽临床实践中的经验,提高对此类疾病诊断的准确率。

摘要: 笔者报道了1例胃腺癌乳腺转移18F-氟脱氧葡萄糖(FDG)PET/CT显像的病例,从临床表现、18F-FDG PET/CT影像学表现、病理诊断及鉴别诊断等方面分析了该病的特点。胃腺癌乳腺转移在临床上罕见,临床表现缺乏特异性,易漏诊及误诊,确诊需经组织病理学检查。18F-FDG PET/CT检查可以早期筛查全身病灶,提高诊断的准确率。Abstract: The authors reported a case of breast metastasis of gastric adenocarcinoma with 18F-FDG PET/CT imaging, and analyzed the disease characteristics from clinical symptoms, manifestation of 18F-FDG PET/CT imaging, pathological diagnosis and differential diagnosis. As the breast metastasis of gastric adenocarcinoma was rare with a non-specific clinical manifestation, it is easy to be missed and misdiagnosed. The disease diagnosis depended on histopathological examination. 18F-FDG PET/CT imaging of total body can detect primary tumor and metastases in an early stage and improve the accuracy of diagnosis.
