Scimitar syndrome nominated by Neil et al. in 1960 is considered as one type of abnormal blood flow in the partial pulmonary vein which is caused by abnormal flow of right pulmonary venous blood into inferior vena cava. On a chest X-ray film, an abnormal shadow like crescent sward of the blood vessel, so called“scimitar sign”or“scimitar shadow”, which is due to abnormal flow of pulmonary vein, is observed over the right lung. In addition, shift and rotation of the heart to the right, hypoplasia of the right lung and abnormal invation of arteries of systemic circulation are often associated with the disease.
Recently, we have observed a case with hypoplasia of the right lung and a cardiac shadow on a chest X-ray film taken over his right thoratic cavity as well as an abnormal shadow, like crescent sward, running from the right of the cardiac shadow towards diaphragma. The observation will be reported in this paper.
