What is a "valley view" ?
It's there among the mammogram images, the 4th image along. It's a view to show the cleavage in clients who have large breasts. The view in the case very nicely shows the skin thickening associated with an inflammatory carcinoma compared with the normal skin of the contralateral breast.
Patchwork mammography of both breasts shows a suspicious lesion centrally in the right breast.
Diffuse skin thickening and subtle suspicious microcalcifications in the left breast.
