The hydatid cyst of the breast is a rare pathology even in countries endemic to tuberculosis, however there remains a differential diagnosis evoked in front of any breast tumor. the clinic, mammography and ultrasound sometimes allow us to suspect the hydatid nature of the lesion. The definitive diagnosis remains histological and the treatment is always surgical. We report an observation of a breast hydatid cyst discovered incidentally.
