Leiomyomas are benign tumors usually found in the uterus although other organs such as the vagina and the ovaries can be involved. The most common etiology of tubal disorders is infection, but tubal leiomyomas remain a rare possibility. We hereby present a case-report of fallopian tube leiomyoma undiagnosed preoperatively despite the technological progress in radiologic imaging. The diagnosis was only made at laparotomy. In this case report, diagnostic measures and the difficulties encountered are discussed.

KEY WORDS: Abdominal mass- Fallopian tube fibroid - Diagnosis.
