Hydatid cyst of fallopian tube

A very rare case of echinococcus granulosus arising in the ovary and the uterus

Hydatidosis is a zoonosis caused by the larval form of a cestode of the species Echinococcus granulosus, the canine tapeworm. It can affect any organ of the human body except nails, hair, and cornea. It most often involves the liver, lungs, muscles, and bones. Involvement of organs in the small pelvis is extremely rare, mainly secondary to dissemination of hydatidosis from another organ, and the ovaries are most often involved, followed by the uterus. We present a 41-year-old Caucasian woman with complaints of mild pain, heaviness in the small pelvis, and a fibroid detected by ultrasound examination. She had reported for 2 previous operations for echinococcus cysts, and we found cystic formations in the liver and pelvis by computed tomography. It was decided that it is a recurrence of echinococcosis with a new cyst both in ovary and uterus. A hysterectomy with adnexectomy was performed, and one year later there is no evidence of recurrence of echinococcosis. In the presence of a formation in the small pelvis, one should always think about echinococcosis, especially if there is evidence of previous manifestations of the disease. Diagnosing this disease is extremely important for proper treatment. As rare as uterine involvement is, this possibility should not be overlooked.

Primary hydatic cyst of the fallopian tube

•Hydatid disease is an endemic infection in the Mediterranean region, and Tunisia is one of the most affected countries.

•The involvement of the female genital tract is uncommon, and the occurrence in the fallopian tube is extremely rare.

•In reproductive organs, the involvement is always secondary. Primary involvement of the fallopian tube is rarely reported.

Hydatid disease is endemic in Tunisia. The involvement of the female genital tract is uncommon, and the occurrence in the fallopian tube is exceptional. We present a case of a 42-year-old woman who had complained of a 4-month history of lower abdominal pain. The abdominal ultrasonography and CT scan showed a multiloculated cystic lesion in the left adnexa. The exploratory laparotomy found a cystic mass developing in the left fallopian tube. Left salpingectomy was performed. The pathological examination confirmed the diagnosis of hydatid cyst disease. No recurrence was detected at the 2-year follow-up. Tubal hydatid cyst is an extremely rare condition that should be considered in the differential diagnosis of any cystic lesion in patients from endemic areas.

Hydatid cyst of the fallopian tube; Case report with literature review

•

Hydatid disease rarely affect the female genital organs.

•

Most cases are seen in the liver and the lungs.

•

Surgery is the main form of treatment which can be done laparoscopically.

Introduction

Hydatid disease is a zoonotic disease which is caused by a parasite belonging to the Echinococcus species. It may affect all part of the body mostly the liver and the lungs, involvement of the fallopian tube is a very rare.

Case presentation

A 30-year-female presented with acute lower abdominal pain, fever and vomiting for 2 days. The past medical history was negative and she had history of surgery for hydatid cyst of the right lobe of liver 3 years before presentation. During examination there was tenderness at the right iliac fossa with guarding. Ultrasound of the pelvic organs showed a left adnexial cyst. During surgery there was an evidence of hydatid cyst involving the left fallopian tube. Left salpingectomy was performed with excision of the cyst. The patient remained three days in the hospital with no reported complication.

Conclusion

Hydatid cyst is one of the differential diagnoses of any cystic lesion in patients from an endemic areas of hydatid disease. Hydatid cysts of the female pelvic organs may be diagnosed initially as ovarian cyst, ovarian tumor, or pelvic infection. Most of the cases are diagnosed during surgery which is the main treatment modality; anthelminthic medications may help to decrease the recurrence rate.
