Scimitar syndrome in a four-month-old infant.

Unlabelled: The Scimitar syndrome or pulmonary venolobar syndrome is a rare, complex and variable congenital anomaly of cardiopulmonary development characterised by an abnormal right-sided pulmonary venous drainage in the inferior vena cava, malformation of the right lung, abnormal arterial supply and sometimes cardiac malformations. These serious anomalies notwithstanding, their presentation is varied, ranging from asymptomatic to severe symptoms, particularly in the neonatal and early infantile period. Some symptomatic cases are misdiagnosed as recurrent lower respiratory tract infections or as heart failure, missing the underlying congenital anomaly.
