Images in a 60–70-year-old sex "2". a There was a hypo-echoic lesion under the hepatic capsule in segment 3 of the liver with a size of 2.2 cm × 2.1 cm. No obvious blood flow signal was detected in the lesion. b No contrast agent filling was found in the arterial phase (timer, 00: 24), portal phase (timer, 01:47), and delayed phase (timer, 02: 26). There was no enhancement in all the three phases. c Enhanced CT showed no obvious enhancement in the lesions. d The resected section of the specimen showed that the lesion was yellow- white and the boundary was clear. A large area of necrotic tissue with surrounding focal inflammatory cell infiltration could be seen (hematoxylin and eosin, × 100)
