Angiographic Findings in Patients with Hepatocellular Carcinoma Previously Treated Using Proton Beam Therapy

Figure 2

A 55-year-old man underwent proton beam therapy (PBT) for hepatocellular carcinoma (HCC) in S5 29 months before the angiography procedure (1). Dynamic computed tomography revealed local recurrence of the PBT-treated HCC (arrow) at the hepatic arterial phase (2). The recurrent HCC exhibited clear tumor staining during the procedure, with several tortuous vessels feeding the lesion (arrowhead), which made it technically difficult to perform selective catheterization (3).
