Meandering pulmonary vein (MPV) is a rarely seen pulmonary vascular anomaly and confused with the scimitar syndrome
or solitary pulmonary nodules.
(SS) is also known as pulmonary venolobar syndrome or hypogenetic lung syndrome which is a rare congenital condition characterised by partial anomalous pulmonary venous connection of right lung to inferior vena cava, dextroposed heart, right lung hypoplasia.
The most common variant of PAPVC is the defect located in sinus venosus malformation i.e, superior caval atrial septal defect coexists with PAPVC.2,3 Other variants include right pulmonary vein draining into right atrium,4 connection of right pulmonary vein to IVC (scimitar syndrome
) and rarely right pulmonary vein connects to azygos vein or coronary sinus.5,6 Similarly, left pulmonary vein may connect to left brachiocephalic vein through an anomalous vertical vein.
The scimitar syndrome
confirmed by 320-slice computerized tomography.
is a partial anomalous venous return of the pulmonary vein to the inferior vena cava (IVC) rather than directly to the left atrium.
is a very rare pathology which occurs with a rate of 2/100 000 and which presents in the infancy, childhood or adulthood with a female/male ratio of 2/1.
Congenital heart defects that have been associated with UAPA are the followings; tetralogy of Fallot, ventricular septal defect (VSD), right aortic arch, truncus arteriosus, patent ductus arteriosus (PDA), CoA, subvalvular aortic stenosis, transposition of the great arteries and scimitar syndrome
(2, 3, 5).
(8) The term 'scimitar syndrome
' first appears in the 1960 article by Neill et al., referring to the combination of anomalous venous drainage of all or most of the right lung to the right atrium or IVC together with hypoplasia of the right lung and associated with systemic arterial collaterals.
6) confirmed the diagnosis of scimitar syndrome
, which is characterised by partially anomalous pulmonary venous drainage, pulmonary lobar hypogenesis and cardiac dextroposition.
