X-Ray Quiz – Discussion – antler sign and third mogul sign<\/em><\/strong><\/span><\/figcaption><\/figure>\n

The annotated image illustrates the salient features including antler sign<\/em> and third mogul sign<\/em>:<\/p>\n

    \n
  1. Upper lobe vessels are prominent, indicating pulmonary venous hypertension. The named signs for prominent upper lobe vessels are: redistribution<\/span>, antler sign<\/span>, upturned mustache sign<\/span> and cephalization<\/span>.<\/li>\n
  2. Right heart border three intercostal spaces and extends well into the right hemithorax, indicating right atrial enlargement. Normally right heart border is just outside the spinal column.<\/li>\n
  3. Prominent left atrial appendage is seen on the left heart border. This is known as third mogul sign<\/span>. First two moguls are aortic knuckle and main pulmonary artery.<\/li>\n
  4. Elevation of left bronchus air column indicating left atrial enlargement. This causes a widening of the carinal angle<\/span> [1].<\/li>\n<\/ol>\n

    A “third mogul” can also occur due to submitral aneurysms and post operative left ventricular pseudoaneurysm after mitral valve replacement [2].<\/p>\n
