Swiss cheese sign (lungs)

A.Prof Frank Gaillard and Dr Ian Bickle et al.

The Swiss cheese sign has been used for the appearance on CT of fluid-containing pneumatocoeles, that typically occur following pulmonary lacerations 1.

The pneumatocoeles appear as 'holes' in the lung parenchyma and hence the description with respect to Swiss-style cheeses (e.g. Emmental), which contain multiple holes.

Other usage

It is sometimes used by pathologists to describe the gross pathological appearance in juvenile papillomatosis of the breast.
