image Clinical Presentation


Asymptomatic 29-year-old woman


image Radiologic Findings


PA (Fig. 11.1) chest X-ray demonstrates a small right lung with ipsilateral mediastinal shift and arcuate tubular opacities that course toward the right cardiophrenic angle. Note that the right bronchus is hyparterial (Fig. 11.1). Contrast-enhanced chest CT (lung window) (Fig. 11.2) demonstrates the small volume of the bilobed right lung. Contrast-enhanced chest CT (mediastinal window) (Figs. 11.3, 11.4) demonstrates paired anomalous pulmonary veins (Fig. 11.3) that drain into the inferior vena cava (Fig. 11.4).
