Mesenteric hydatid cyst: An unusual presentation

Abstract

Hydatidosis is a common zoonosis that affects a large number of humans and animals, especially in poorly developed countries. Mesenteric hydatid cysts are rare intra abdominal lesions with variable clinical symptoms and signs that make preoperative diagnosis diffi cult. The treatment is surgical excision followed by mebendazole for four months. We report this unusual case where preoperative diagnosis of right tubo-ovarian mass was made and the diagnosis of mesenteric hydatid cyst could be made only on laprotomy and microscopic examination after surgery.

Korean Society of Obstetrics and GynecologyHydatid disease is a zoonotic infection caused by larval stages of cestode Echinococcus granulosus (family taeniidae) and rarely by Echinococcus multilocularis. Dogs and other carnivores are defi nitive hosts where as sheep and ruminants are intermediate hosts.Man becomes an accidental host by consuming vegetables and water contaminated with hydatid ova. Although liver (75%) and lung (15%) are the most commonly involved organs, the disease can be seen anywhere in the body (10%) [1,2]. Bickers [3] after reviewing 532 cases of hydatid disease from an endemic area over a 20 year period recorded only 12 instances of hydatid cyst in pelvis. Case ReportA 35-year-old lady para two live two presented with pain lower abdomen for two years. The pain was dull in nature. There was no change in her bowel and bladder habits. She was para two live two and was using barrier contraceptive. Her menstrual cycle was regular. On physical examination vitals were stable. Her abdominal examination was unremarkable. On per speculum examination cervix and vagina was healthy. Per vaginum examination revealed normal size anteverted uterus deviated to left side. The mobility of the uterus was restricted. A large cystic mass measuring about 6×6 cm was palpable in the right fornix which was adherent to the uterus. Left adnexa were normal. On per rectal examination there was no nodularity in the pouch of Douglas and rectal mucosa was free. The routine laboratory investigations were within normal limits. X-ray chest and ultrasound (USG) upper abdomen was normal. USG lower abdomen and pelvis showed normal size uterus with a large multicystic septated mass in the right adnexa measuring 11×7 cm. Left adnexa was normal. Her CA-125 was normal. Diagnosis of right adnexal cyst was made and she was planned for exploratory laprotomy. Intra operatively a cyst measuring 10×6 cm was seen arising from the mesentery and was CASE REPORT Korean J Obstet Gynecol 2012;55(5):358-360 http://dx
