Overview
The findings on chest radiography vary depending on the type of anatomic variant of total anomalous pulmonary venous connection (TAPVC). Snowman sign is considered pathognomonic for the diagnosis of total anomalous pulmonary venous connection.
X Ray
X-ray findings suggestive of the total anomalous pulmonary venous connection include:[1]
- Unobstructed:
- Snowman sign: A large supra cardiac shadow due to the anomalous pulmonary vein and persistent left superior vena cava can be seen, which together with normal cardiac shadow forms a snowman appearance.
- This x-ray finding is considered pathognomonic for the diagnosis of total anomalous pulmonary venous connection.
- Mild dilatation of the pulmonary arteries.
- Mild cardiomegaly
- Snowman sign: A large supra cardiac shadow due to the anomalous pulmonary vein and persistent left superior vena cava can be seen, which together with normal cardiac shadow forms a snowman appearance.
- Obstructed:
- Pulmonary vein congestion
- Dilatation of the pulmonary arteries
- Pulmonary edema
