Inflammatory myofibroblastic tumors (IMT) are an uncommon mesenchymal solid tumor commonly documented in children and young adults (Kim et al., 2012 [1]). Cecum is a rare location of this entity, may simulating a malignant tumor process.
A 71 year old patient was admitted for pain in the right iliac fossa with chronic constipation evolving for two months associated with weight loss. As a diagnosic step, an abdominal computed tomography (CT) scan was performed showing a thickening of the cecal wall. There was no regional or distant metastasis. During a colonoscopy, many biopsies have been returned to a non-specific chronic colitis; as a result, the IMT of the cecum was confirmed pathologically after ilio-coecal resection.
IMT is difined as a solid mesenchymal tumor basically affects the soft parts as well as the visceral organs. The litterature show that frequent localisations are pulmonary and intra-orbital (Krzysztof Siemion et al., 23 February 2022); therefore, the cecal location is very rare may mimic a malignant tumor (Mauricio Gonzalez-Urquijo et al., January 20, 2020), It is worth recalling that the imaging outcomes are polymorphic and inconclusive; in addition, Surgical excision is the treatment of choice for IMT (Alireza Mirshemirani et al., Dec 2011) and the histopathology is still required for the final diagnosis.
Radiologic features of IMT present a diagnostic challenge to the radiologist; also, mimic malignancy may lead to unnecessary investigations.
炎性肌纤维母细胞瘤(IMT)是一种罕见的间叶性实体肿瘤,常见于儿童和年轻人(Kim等人,2012 [1])。盲肠是该实体瘤的罕见发病部位,可能会模拟恶性肿瘤过程。
一名71岁患者因右下腹疼痛、慢性便秘持续两个月并伴有体重减轻入院。作为诊断步骤,进行了腹部计算机断层扫描(CT),显示盲肠壁增厚。无区域或远处转移。在结肠镜检查期间,多次活检结果均为非特异性慢性结肠炎;因此,在进行回盲部切除术后,病理证实为盲肠IMT。
IMT被定义为一种实体间叶性肿瘤,主要影响软组织和内脏器官。文献表明,常见的发病部位是肺部和眶内(Krzysztof Siemion等人,2022年2月23日);因此,盲肠部位非常罕见,可能会模仿恶性肿瘤(Mauricio Gonzalez-Urquijo等人,2020年1月20日)。值得一提的是,影像学表现具有多态性且无定论;此外,手术切除是IMT的首选治疗方法(Alireza Mirshemirani等人,2011年12月),最终诊断仍需组织病理学检查。
IMT的放射学特征给放射科医生带来了诊断挑战;此外,模仿恶性肿瘤可能导致不必要的检查。
