  14. 場景(2)：影像與專科檢查(1) • Chest X-ray: no active lesions are found in lungs, mediastinum, heart, airway, diaphragm and cheat wall • Abdominal ultrasound: coarse liver parenchyma, uneven surface, splenomegaly (splenic index 32 cm2), moderate ascites, a 2.5cm hypoechoic nodule at segment 5, normal gallbladder and biliary tracts, patent portal vein.

  15. 場景(2)：影像與專科檢查(2) • CT of liver (with and without contrast/dynamic study): a 2.8cm liver tumor with hyper-density in arterial phase and hypo-density in portal phase and delay phase, cirrhotic liver parenchyma, ascites and splenomegaly were also found • Esophago-gastro-duodenoscopy (EGD): Some form-1 blue color varices without red color sign at lower third of esophagus, no gastric varices, no peptic ulcer found
