Low-grade appendiceal mucinous neoplasm (LAMN) is rare disease, and the absence of characteristic clinical symptoms makes preoperative diagnosis difficult. The strategy of treatment for LAMN has not been established. Surgical approach and lymph node (LN) dissection are still controversial. We herein present a case of LAMN with difficulties in making the preoperative diagnosis, which exhibited invagination and was treated by laparoscopy-assisted ileocecal resection with LN dissection. When cystic mass is detected in the bowel, LAMN or mucinous adenocarcinoma should be considered as a different diagnosis. And the laparoscopy-assisted ileocecal resection is a feasible operation for LAMN with careful procedure.
低级别阑尾黏液性肿瘤（LAMN）是一种罕见疾病，缺乏特征性临床症状使得术前诊断困难。LAMN的治疗策略尚未确立。手术方式和淋巴结清扫仍存在争议。我们在此报告一例术前诊断困难的LAMN病例，该病例表现为肠套叠，通过腹腔镜辅助回盲部切除术加淋巴结清扫进行治疗。当在肠道中检测到囊性肿块时，应考虑LAMN或黏液腺癌作为鉴别诊断。对于LAMN，腹腔镜辅助回盲部切除术是一种可行的手术方式，手术过程需谨慎。
