Figure 8. (A) Chest radiography combined with a schema showing increased vascularity. (B) Chest computed tomography (CT) shows treated pulmonary arteriovenous malformations at the left and right upper lobe (arrow). Two months after the initial embolization, chest CT shows a worsening infiltrating shadow in contact with the pleura in the left lung upper lobe (triangle). (C) Angiography shows proliferation of the bronchial artery, internal thoracic artery, and thyroid carotid artery flowing into the lesion. Four-dimensional CT also shows the dilated and tortuous left ITA flowing into the lesion. BA – bronchial artery; ITA – internal thoracic artery; TCA – thyroid carotid artery.
