Abstract:

Pelvic splenosis is a rare clinical phenomenon, usually caused by ectopic implantation of splenic tissue due to splenic trauma or surgery. Most patients with this disease have no obvious clinical symptoms and it is often incidentally detected during imaging examinations. Due to its special anatomical location and imaging features, it is very easy to be confused with ovarian tumors, resulting in a relatively high misdiagnosis rate. This paper reports a case where the preoperative ultrasound examination showed a solid mass in the adnexal area. Without considering the patient′s history of partial splenectomy, pelvic splenosis was misdiagnosed as an ovarian tumor. The aim is to improve the clinical physicians′ awareness of this disease, provide references for clinical diagnosis and differential diagnosis, and thus reduce the occurrence of misdiagnosis and mistreatment.
