Intussusception is the invagination of a segment of bowel (intussusceptum) into the lumen of an adjacent segment (intussuscipiens). Adult intussusception is rare and typically asymptomatic, although bowel obstruction can be a predominant symptom, making it difficult to diagnose. Splenosis is an uncommon and benign disease, arising from the self-implantation of splenic tissue elsewhere in the body after splenectomy or splenic trauma. Colocolic intussusception secondary to splenosis is rare. We report a case of colon intussusception with a mass in the intussusception detected by ultrasound. Abdominal ultrasound identified the intussusception location but failed to distinguish its pathological properties. Colonoscopy revealed the exudation of necrotic and fibrous tissue. Surgery was performed because of suspicions of a malignant tumor.
肠套叠是指一段肠管（套入部）嵌入相邻肠管的腔（套入肠）内。成人肠套叠罕见且通常无症状，尽管肠梗阻可能是主要症状，导致难以诊断。脾组织植入症是一种罕见的良性疾病，源于脾切除或脾外伤后脾组织在体内其他部位的自行植入。由脾组织植入症引起的结肠肠套叠则更为罕见。我们报告了一例超声检查发现肠套叠合并套叠内肿块的病例。腹部超声可确定肠套叠的位置，但无法区分其病理性质。结肠镜检查显示坏死和纤维组织渗出。由于怀疑为恶性肿瘤，因此进行了手术。
