Background:hydatid disease (Echinococcus granulosus), is a parasite disease infestation in humans most commonly occurs in the liver. It has high recurrence rate. Surgery remains the mainstay of treatment for HD and aims to eliminate the parasite, promoting the rapid disappearance of any residual cavity and preventing complications and recurrence . Case study:our patient is a case of recurrent huge hydatid cyst which infested in the liver of 39-year-old female, medically free, in 2009 she underwent evacuation of hydatid cyst with partial removal of the cyst wall. 7 years later (2016) she presented to ER with abdominal mass increasing in size with time, associated with dull, aching pain and vomiting, with jaundice and itching, there was no fever, no change in bowel habit, no change in urine and stool color. A full investigation done, abdominal CT showed large oval shaped intraperitoneal cystic lesion with a diameter about 20 cm * 15 cm. The patient received anti-parasitic medications for 2 weeks before the operation. The operation of complete cyst excision (cystectomy) was done. We recommend a total or partial pericystectomy as the most appropriate procedure for the management of primary hydatid cyst and also for recurrent hydatid cyst with pre- and post-operative courses of anti-parasitic drugs should be considered which helped in reducing the intraoperative spillage of viable cysts and to decrease the recurrence rate post-operatively, and the patient has to avoid the risk factors and transmission ways of the parasite.
