A 43-year-old woman (gravida 2, para 1011) with a history of uterine leiomyomata and a Barnett colonic reservoir underwent a supracervical hysterectomy. Final pathology revealed Enterobius vermicularis within the myometrium and adnexal vasculature. Infection may have occurred through a modified mode given the presence of a Barnett colonic reservoir and absence of an anus.
