Enterobius vermicularis may invade female genital organs and become symptomatic when there is involvement of the fallopian tube and/or ovary.
Sites of involvement may include:
(1) endometrium
(2) fallopian tube
(3) ovary
(4) adjacent peritoneum
Clinical features may include:
(1) lower abdominal pain
(2) fever
(3) dyspareunia
(4) ectopic pregnancy
(5) peritonitis
Imaging studies may show an adnexal mass.
The diagnosis is usually made by demonstration of the egg or gravid female in histologic sections of a resected specimen. It often elicits a granulomatous response.
The presence of salpingitis, oorphoritis or tubo-ovarian abscess in a woman with known Enterobius salpingitis might suggest the diagnosis but would be insufficient to establish it.
