Adnexal fascioliasis masquerading as ovarian cancer.

BACKGROUND

Preoperative diagnosis of ovarian cancer is still problematic as multiple disease processes may present with pelvic mass. Fascioliasis is a parasitic disease producing unique clinical manifestations.

CASE REPORT: A 49-year-old female patient admitted to our hospital with the complaint of occasional abdominal pain. Pelvic examination revealed a right adnexal mass. Serum CA-125 level was elevated. Explorative laparotomy was performed with the initial diagnosis of ovarian tumor. Final diagnosis was adnexal fascioliasis.

CONCLUSION

In the setting of a newly diagnosed pelvic mass, care should be taken when interpreting an elevated CA-125 level. While ovarian cancer is high on the list of differential diagnoses, atypical clinical presentation of fasciola may give rise to a misdiagnosis of malignancy.
