摘要 BACKGROUND Low-grade appendiceal mucinous neoplasm(LAMN)is extremely rare and easily misdiagnosed before surgery.CASE SUMMARY We report the treatment of an asymptomatic case of LAMN diagnosed by magnetic resonance imaging(MRI)and surgical findings.A 70-year-old woman presented with an adnexal mass found by physical examination in July 2020.Gynecologic ultrasonography revealed a cystic mass in the right adnexa,and computed tomography showed a cystic mass in the pelvic cavity.All tumor markers were normal.A further MRI examination suggested mucinous neoplasm in the right pelvic cavity,excluding the possibility of adnexal cyst.Laparoscopic exploration found a huge cystic mass of about 10 cm×7 cm that originated from the apex of the appendix,with spontaneous rupture.LAMN was confirmed by pathological examination.As of May 2021,no disease recurrence occurred after an open appendectomy.CONCLUSION This case indicates that we should pay more attention to female patients who are clinically diagnosed with an adnexal mass at admission,.The physical examination should be done carefully,and the laboratory and imaging examination results should be comprehensively analyzed to avoid misdiagnosis and to ensure prompt diagnosis and treatment,and to improve prognosis.MRI may be a better option for the diagnosis of appendiceal mucinous neoplasm.
