Lesions Presenting with Diminished Pulmonary Vascularity

These are exceedingly rare in the adult patient and include patients with untreated Tetralogy of Fallot (see figure below) and Ebstein's anomaly (see previous). The former tend to have normal size hearts or mild cardiomegaly; the latter may have marked cardiomegaly if severe.
