Inflammatory myofibroblastic tumor (IMT) is an intermediate tumor composed of differentiated myofibroblastic spindle cells with inflammatory cell infiltration. It can occur in all parts of the body, with the lungs being the most common, while the tissues outside the lungs, including the sigmoid colon, are rare. Herein, we present a case of a 10-year-old girl with sigmoid IMT who presented to our hospital with abdominal pain. An abdominal computed tomography (CT) revealed a well-defined, slightly low-density mass in her lower abdomen that was not clearly demarcated from the sigmoid colon. The mass showed significant uneven enhancement on contrast-enhanced CT and increased fluorine-18 fluorodeoxyglucose (F-FDG) uptake on positron emission tomography (PET). Moreover, a systematic review of the published literature on sigmoid IMT was conducted and its clinical and radiographic features were summarized to increase the understanding of this rare disease.
炎性肌成纤维细胞瘤（IMT）是一种由分化的肌成纤维细胞梭形细胞伴炎性细胞浸润组成的中间型肿瘤。它可发生于身体的各个部位，其中肺部最为常见，而肺外组织，包括乙状结肠则较为罕见。在此，我们报告一例10岁患有乙状结肠IMT的女孩，她因腹痛前来我院就诊。腹部计算机断层扫描（CT）显示其下腹部有一个边界清晰、密度略低的肿块，与乙状结肠分界不清。该肿块在增强CT上表现出明显不均匀强化，在正电子发射断层扫描（PET）上氟-18氟脱氧葡萄糖（F-FDG）摄取增加。此外，我们对已发表的关于乙状结肠IMT的文献进行了系统回顾，并总结了其临床和影像学特征，以增进对这种罕见疾病的了解。
