Hypertension in the liver clinic - polyarteritis nodosa in a patient with hepatitis B

Figure 1 Triple phase dynamic contrast enhanced computed tomography performed for the upper abdomen showed features of chronic liver disease, predominantly on the portal venous phase. A: Subtle sign of periportal space widening (white arrow) and few small collaterals in the peri-gastric location (blue arrow) suggesting features of chronic liver disease on computed tomography scan; B: Irregular liver margins seen better in the inter-lobar fissure (red arrow) with mild caudate enlargement (yellow arrow) and perigastric collaterals (white arrow).
