Images in a 40–50-year-old sex "2". a There were two hypo-echoic lesions in segment 7 of the liver which connected like a dumbbell. Normal hepatic blood vessels could be seen inside (the lesions connected portion) and around the lesions. b In the arterial phase (timer, 00:24), the lesions showed thin peripheral rim-like enhancement, and the thickness of the enhanced ring was 0.23 cm; this showed iso-enhancement in the portal phase (timer, 00: 57) and delayed phase (timer, 02: 03). There was no contrast agent filling in the interior of the lesions. c Enhanced CT showed no obvious enhancement in the lesions but showed enhanced blood vessels. d A large area of necrotic tissue with surrounding inflammatory cell infiltration could be seen (hematoxylin and eosin, × 100)
