Causes of Malformation of Uterine Appendage Misdiagnosed as Pelvic Mass
Objective To improve the understanding of accessory cavitated uterine malformation(ACUM)and to re-duce the misdiagnosis rate of ACUM.Methods The clinical data of an ACUM patient initially diagnosed with pelvic mass in April 2024 were retrospectively analyzed.Results A 37-year-old woman was admitted to the hospital due to small pelvic mass detected during physical examination in other hospitals,which was not paid attention to and left untreated.After regular follow-up,the mass was found to be gradually increasing.Considering the nature of pelvic masses to be unknown,laparoscopic exploration was performed after improving the preoperative examination to find the cavity and endometrioid tissue,and hyster-ectomy was given.Postoperative pathological examination revealed ACUM.The misdiagnosis lasted more than 1 year.After 4 months of follow-up,the patient recovered well and no other complications or discomfort were observed.Conclusion ACUM is a kind of disease with very low incidence that is prone to misdiagnosis and missed diagnosis,and there are no specific symp-toms in the early clinical stage.When receiving such patients,clinicians should timely broaden their diagnostic thinking and consider the possibilities of more diseases,so as to reduce the risk of misdiagnosis.
