Endometriosis is a well-described pathology, with anatomic location of endometrial cell implantation extending both intraperitoneal and rarely extraperitoneal. Interestingly, previous reports indicated that the spleen enjoys immunity to endometriosis. Here, we present a patient with unremitting abdominal pain who, upon further workup, revealed multicystic disease of the spleen. The patient underwent an open splenectomy with pathology revealing intraparenchymal endometriosis likely due to seeding from traumatic splenorrhaphy. Two-week follow-up demonstrated resolution of symptoms and a well-healing incision with no postoperative complications.
