Preoperative computed tomography (CT), angiography before embolization, and plain CT after embolization with lipiodol and N-butyl-2-cyanoacrylate. (A), (B) Preoperative CT showed a giant pelvic mass lesion, measuring 30 × 25 × 19 cm. (C) Angiography of the left iliac artery revealed that the mass was mainly supplied by the left obturator artery (black arrow), left internal pudendal artery (white arrow), and left superior vesical artery (red arrow). (D), (E), (F) CT after embolization showed that lipiodol and N-butyl-2-cyanoacrylate were well distributed to the left obturator artery (black arrow), left internal pudendal artery (white arrow), and left superior vesical artery (red arrow), demonstrating successful embolization of the target vessels.
