Case 5 / 2017 - Scimitar Syndrome and Pulmonary Sequestration in Natural Progression in a 68-Year-Old Woman

Normal pulmonary trunk (22 mm). Dilated left pulmonary artery (27 mm) with increased pulmonary artery-to-bronchus ratio, which may indicate either redirection of the flow or increased pulmonary pressure. Right pulmonary artery was tortuous and hypoplastic, measuring 10 mm in its proximal portion and 9mm in its medial third (Figure 1D). Enlarged branch (13 x 13 mm) from the abdominal aorta at the level of the celiac trunk with ascending course to the posterior-inferior region of the right lung (“aneurysmatic” pulmonary sequestration). Hypoplastic right lung with compensation by the left lung. Posterolateral diaphragmatic discontinuity, suggestive of Bochdalek hernia.
