A 69 year old woman presented with septic shock secondary to a urinary tract infection. A chest radiograph (Figure 1) done after uneventful placement of a left internal jugular central line showed aberrant position of the catheter.
Review of a past contrast-enhanced CT chest (Figure 2) revealed an anomalous pulmonary venous return with a pulmonary vein draining to the brachiocephalic vein.
Partial anomalous pulmonary venous return (PAPVR) is a rare congenital defect which results in a left-to-right shunt. The prevalence was 0.1% in one retrospective study of 45,538 contrast-enhanced chest CT scans (1). Diagnosis can be made with echocardiography, angiography, right heart catheterization, or computed tomography. PAPVR is traditionally associated with atrial septal defects, and patients are often asymptomatic. Clinical manifestations occur when there is significant shunting and include syncope, right heart failure, and pulmonary hypertension (2).
