Figure 4b. (a) Selective left subclavian angiogram in a 41-year-old man with recurrent episodes of massive hemoptysis shows an enlarged and tortuous lateral thoracic artery (arrow) with shunting to pulmonary artery. Also note parenchymal destruction as a result of previous pulmonary tuberculosis. (b) Transverse 1.25-mm-thick CT image shows tortuous vascular structure (arrow) in subpleural fat with thickening of adjacent pleura (arrowhead). (c) Three-dimensional volume-rendered CT image shows a tortuous artery (arrow) arising from left subclavian artery (arrowhead).
