In pulmonary venous hypertension, they become less prominent due to vasoconstriction in the lower zones so that there is a redistribution of pulmonary blood flow to the upper zones.<\/p>\n<p>Pulmonary venous hypertension is one of the important features of mitral stenosis which can be recognized on CXR. It can also occur in other conditions which cause elevation of left atrial pressure, which is directly transmitted to the pulmonary veins. Cephalization of pulmonary vascular marking can be a feature in heart failure.<\/p>\n<p>Antler has also been described in torsion of the lung, a rare condition [2]. Torsion of the lung can be either of the whole lung or a single lobe. It can occur spontaneously in association with other anomalies. Torsion of the lung may also occur after a traumatic pneumothorax or after thoracic surgery.<\/p>\n<p><strong><span style=\"color: #0000ff;\">References<\/span><\/strong><\/p>\n<ol>\n<li>Han J, Xiang H, Ridley WE, Ridley LJ.&nbsp;<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30309174\">Antler sign: Pulmonary venous hypertension<\/a>.&nbsp;J Med Imaging Radiat Oncol. 2018 Oct;62 Suppl 1:13.
