Primary or secondary it stills a rare localization, accounting for 1% of the thoracic locations. We report a case of a hydatid cyst of diaphragm in a 57 -year-old female who was admitted to our clinic for right basithoracic pain. CT reported a giant hydatid cyst including multiple vesicles at the right lower thoracic cavity. Surgical exploration revealed an independent giant diaphragmatic hydatid cyst. We performed cystotomy and more than 100 daughter vesicles were removed from the cyst. The rest of the giant cyst cavity was excised. Keywords: Multivesicular Hydatid Cyst, CT
