Abdominal ectopic splenosis in pregnancy: A case report

Ectopic splenosis is a disorder caused by the overflow of splenic myeloid cells or intravascular migration after splenic trauma or splenectomy. It is often asymptomatic and detected incidentally during imaging evaluation. Splenosis lacks specificity on clinical imaging examinations such as ultrasound, computed tomography, and magnetic resonance imaging and is often confused with tumors. We report the case of a primigravida (G1P0) in her early 30s with multiple hypoechoic masses in her upper abdomen that were detected during routine prenatal ultrasound at 23 + 1 weeks of gestation, with a recommendation for follow-up monitoring. Tumor marker analysis showed normal results. The patient remained asymptomatic without abdominal pain or fever, and monitoring showed normal fetal heart rate. The patient was admitted to our hospital, and we conducted a multidisciplinary consultation. We used misoprostol and a Cook balloon to induce labor; the patient delivered vaginally successfully. In this case report, we aimed to highlight the significance of taking detailed medical history and using the "minimal intervention" approach for managing pregnancy-complicated splenosis, highlighting the pivotal role of multimodal imaging evaluation.
