[Scimitar sign in a partially anomalous pulmonary venous drainage]. / Signo de la cimitarra en un drenaje venoso pulmonar anómalo parcial.

The scimitar sign is an uncommon finding, that shows an anomalous pulmonary vein coursing to the right cardiac border, that drains to the inferior vena cava. Usually it is associated to other cardiovascular or pulmonary anomalies, within the hypogenetic lung syndrome. We present a rare case of a few symptomatic man 46 years-old, with partial anomalous pulmonary venous drainage, diagnosed upon finding the scimitar sign in a roentgenogram of the chest, in absence of the hypogenetic lung syndrome. We comment the role of CT in the diagnosis.
