Conclusion and Results
According to the present study, hydatid cysts of the peritoneum and omentum, despite considerably low prevalence, may occur in association with hydatid cysts in other regions of the body, including the liver and spleen. Although these cysts are usually a result of abdominal trauma or hydatid cyst surgery, they can also be caused by hematologic or lymphatic dissemination or by rupture of the cyst adventitia. CT scan still remains the best diagnostic method for hydatid cyst, but the appearance of peritoneal and omental hydatid cyst may be mistaken for malignant lesions and peritoneal seeding. This case is significant as misdiagnosis may delay treatment and lead to risks of rupture, peritonitis and anaphylactic shock and imminent death. Surgery and removal of the cyst along with anthelmintic treatment is the best method of treatment in these cases and can prevent the aforementioned complications and improve the survival of the patients.
