Abstract
Hydatid cyst of the breast is endemic in some areas like sheep-raising countries. The location of the disease is mostly in the liver and lungs. We presents a case of 66-year-old female with hydatid cyst of the breast diagnosed pre-operatively by core needle biopsy. Complete radiology workup are also provided which includes mammography, ultrasound, and computed tomography images. Hydatid cyst of the breast is extremely rare even in endemic areas, its only accounts for 0.27% of all cases. Only few reports are published in the literatures about breast hydatid cyst and majority of cases have been diagnosed post-operatively with no complete radiology workup.
