Inflammatory myofibroblastic tumors (IMT) of the urachus is a rare neoplastic condition characterized by proliferation of spindle cell, likely derived from myofibroblasts or fibroblasts, with acute and chronic inflammatory infiltrate. Urachal IMT present with abdominal/pelvic pain and urinary symptoms. These often manifest as abdominal mass involving adjacent structures. We describe a case of young female with urachal IMT that was excised with a wide margin to ensure complete removal of all adjacent affected tissue using robotic-assisted laparoscopic approach. Immunohistochemical evidence of ALK and ALK gene rearrangement were confirmed in this tumor which are diagnostic of IMT.
脐尿管炎性肌纤维母细胞瘤（IMT）是一种罕见的肿瘤性疾病，其特征为梭形细胞增殖，可能起源于肌成纤维细胞或成纤维细胞，并伴有急慢性炎症浸润。脐尿管IMT表现为腹部/盆腔疼痛和泌尿系统症状。这些症状常表现为累及相邻结构的腹部肿块。我们描述了一例年轻女性脐尿管IMT病例，采用机器人辅助腹腔镜手术，广泛切除肿瘤边缘以确保完全切除所有相邻的受累组织。该肿瘤经免疫组织化学证实存在ALK及ALK基因重排，这是IMT的诊断依据。
