We describe a case of reactive nodular fibrous pseudotumor (RNFP) misdiagnosed as lymph node metastasis after gastric cancer surgery. Additionally, we summarize the clinical and imaging characteristics of RNFP, combined with the literature, to improve the understanding of preoperative diagnosis. Radiological features of RNFP are a homogenous, isodense, solid mass with gradually mild enhancement on multiphasic abdominal computed tomography (CT), and slight F-FDG uptake by positron emission tomography/computed tomography (PET/CT). To the best of our knowledge, this is the first report in the English literature of a case of reactive nodular fibrous pseudotumor associated with gastric cancer and its appearance on PET/CT images.
我们描述了1例胃癌手术后被误诊为淋巴结转移的反应性结节性纤维假瘤（RNFP）病例。此外，我们结合文献总结了RNFP的临床和影像学特征，以提高对术前诊断的认识。RNFP的放射学特征为在多期腹部计算机断层扫描（CT）上呈均匀等密度实性肿块，强化逐渐轻微，在正电子发射断层扫描/计算机断层扫描（PET/CT）上有轻微的F-FDG摄取。据我们所知，这是英文文献中首例关于与胃癌相关的反应性结节性纤维假瘤病例及其在PET/CT图像上表现的报道。
