The stag's antler sign, also known as the hands-up or inverted moustache sign, refers to upper lobe pulmonary venous diversion in pulmonary venous hypertension or pulmonary edema as seen on an erect frontal chest radiograph.

The prominence of upper lobe pulmonary veins resembles a stag's antlers. It is the earliest sign of pulmonary venous hypertension (grade 1 pulmonary edema).

Rarely a unilateral form has been described ⁵.

This is not to be confused with the antler sign described for lung torsion.
