Chassaignac bag

Chassaignac bursa or space is historically described but is rarely used in modern practice. It refers to the space containing only connective tissue and lying between the pectoralis fascia posteriorly and deep layer of superficial fascia anteriorly. 

Due to this space, the breast can move freely in relation to the chest wall. It is seen as lucency in the mammogram and its radiological significance lies in the fact that it must be seen in all optimally performed craniocaudal and mediolateral oblique mammograms.
