Computed tomography images of the left lower lobe performed 1 month after starting anastrozole. Upper and lower columns show serial images of axial and coronal views, respectively. Continuity between a feeding artery (white arrow) and a draining vein (black arrow) via the sac (arrowhead).

Additionally, there were abnormal dilated vessels in the left lower lobe (segment 10) of the left lung (Fig. 1).

Postoperatively, the patient received adjuvant chemotherapy with adriamycin, cyclophosphamide, paclitaxel, and trastuzumab in combination with tangential radiation (Fig. 2).
Computed tomography images performed 5 months after starting exemestane. Upper and lower columns show serial images of axial and coronal views, respectively. The affected pulmonary artery (white arrow) and pulmonary vein (black arrow) are markedly decreased in size, which appear almost equal to those of normal vessels. The sac is also obviously shrunk and appears scar-like (arrowhead).

Contrast-enhanced CT was performed 5 months after starting exemestane for preoperative evaluation of embolotherapy, which showed that the affected vessels of the PAVM had obviously decreased in size, and the fistula had almost disappeared (Fig. 3).
