Primary hydatid cyst of the fallopian tube: A case report.

BACKGROUND

Human hydatid disease is caused by echinococcus granulosus and has a global distribution. It mainly affects the liver, but can involve other organs. In this paper, we present a case of a primary hydatid cyst of the fallopian tube.

CASE PRESENTATION: A 69-year-old (gravida 16, para 16 woman) with abdominal pain and urinary frequency was presented to the Gynecology Clinic of Imam Khomeini Hospital Sari, Iran, in September 2011. On physical examination, there was a nontender abdominal mass under umbilicus. The sonography of abdomen and pelvic showed a multiloculated mass with thick septation in right adnexa suggesting mucinous ovarian tumor, while the uterus, left adnex, liver, spleen and kidneys were all normal. The patient's chest x-ray was normal. Serum tumor markers including CEA, CA125, αFP and βHCG were negative. An exploratory laparotomy was performed. There was a 20 cm firm elastic mass in the anterior surface of uterus originated from the right fallopian tube and was removed. Hydatid cyst was confirmed by pathological examination.

CONCLUSION

Although primary hydatid cyst of genital tract is rare, in high prevalence countries it should be considered.
