Inflammatory fibroid polyp is a rare benign lesion originating from the submucosa of the gastrointestinal tract. Inflammatory fibroid polyp in the small bowel commonly presents with intussusception and bowel obstruction. We report two cases of inflammatory fibroid polyps as rare causes of intussusception in adult patients, and review the literature on imaging features of inflammatory fibroid polyps. Due to its well-defined and smooth outline as well as homogeneous appearance and low attenuation on computed tomography, diagnostic difficulty may be encountered as it can be easily missed for a complicated intussusception complex. Lead points must be carefully looked for in adult patients presenting with intussusception.

成人炎性纖維性息肉致腸套疊:兩宗病例報告和放射影像學特徵的文獻回顧

李芷茵、袁銘強

 

炎性纖維性息肉源自胃腸道的粘膜下層,是一種罕見的良性病變。小腸中的炎性纖維性息肉通常以腸套疊及腸梗阻起病。本文報告兩名病因為罕見的炎性纖維性息肉的腸套疊成人患者,並回顧炎性纖維性息肉影像學特徵的文獻。由於炎性纖維性息肉分界清晰、輪廓光整、電腦斷層掃描圖像性質均勻、低衰減,診斷可能有困難;而且可能因解剖輔助的腸套疊體部而漏診。診療腸套疊的成人患者必須仔細尋找導引點。
