Fig. 1From: Partial hepatectomy for a patient with Rendu–Osler–Weber disease: a case reportPreoperative images. At the initial visit, CT showed multiple lesions of up to 75 mm in both lobes of the liver (arrows). In the arterial phase, the common and proper hepatic artery (arrowhead) was markedly dilated and tortuous. The lesions were slightly enhanced, and the liver parenchyma was strongly enhanced from the arterial phase and was very heterogeneous due to small telangiectasias (a). In the portal phase, the lesions showed delayed enhancement (b). MRI showed that lesions were enhanced in the hepatocellular phase. During 8 years of follow-up, the only lesion to increase in size was a segment 6 lesion (arrow); this tumor increased in diameter from 30 to 50 mm (c)Back to article page
