Inflammatory fibroid polyps (IFPs) are uncommon lesions of the gastrointestinal tract. Only scattered case reports have appeared in the radiology literature. The authors reviewed the cases of 33 patients (20 women and 13 men; average age, 45 years) to determine if these polyps had any distinctive diagnostic radiologic features. The IFPs were located in the stomach (n = 16), small bowel (n = 13), and colon (n = 4). The lesions originated in the submucosa and were composed of fibroblasts, inflammatory cells, and a network of blood vessels. Gastric IFPs were most often located in the antrum and were usually ulcerated. Most of the patients presented with clinical evidence of gastrointestinal blood loss. Small bowel polyps were usually located in the ileum, and patients were typically older women with intestinal obstruction due to intussusception. Most of the lesions appeared as large, intramural masses at radiologic examination. Some of the lesions were pedunculated, and all were solitary. There were no distinctive features to differentiate IFPs from other mural or intraluminal lesions of the gastrointestinal tract.
炎性纤维性息肉（IFP）是胃肠道的罕见病变。放射学文献中仅有零散的病例报告。作者回顾了33例患者（20名女性和13名男性；平均年龄45岁）的病例，以确定这些息肉是否具有任何独特的诊断性放射学特征。IFP位于胃（n = 16）、小肠（n = 13）和结肠（n = 4）。病变起源于黏膜下层，由成纤维细胞、炎性细胞和血管网络组成。胃IFP最常位于胃窦，且通常有溃疡形成。大多数患者有胃肠道失血的临床证据。小肠息肉通常位于回肠，患者通常为老年女性，因肠套叠导致肠梗阻。大多数病变在放射学检查中表现为大的壁内肿块。一些病变有蒂，且均为单发。IFP与胃肠道其他壁内或腔内病变之间没有可资鉴别的独特特征。
