Fig. 1E. 54-year-old man referred for evaluation of tubular density on
chest radiograph. Three-dimensional volume-rendered CT was performed 7 years
after angiography in A-C. Left lateral oblique CT of thorax (D)
shows lingular vascular malformation (a) that drains by straight small vessel
(open arrow) to left superior pulmonary vein (curved arrow)
and by larger parallel vessel (arrowhead) to left pulmonary artery
(straight solid arrow). Superior view CT of lower thorax and upper
abdomen (E) shows large tortuous feeding systemic artery (thick
white arrow) in left upper abdomen arising from celiac axis (black
arrow) and feeding vascular malformation in lingula (thin white
arrow). Left lateral CT of thorax (F) shows second posterior chest
wall vascular malformation (a) fed by two small intercostal arteries
(small black arrows) and one large intercostal artery (long thin
black arrow) from descending thoracic aorta. Single straight vessel
(white arrows) drains to left lower lobe pulmonary artery (open
arrow).
