Review to better understand the macroscopic subtypes and histogenesis of intrahepatic cholangiocarcinoma

Table 8 Radiologic studies of combined hepatocellular-cholangiocarcinoma

Ref.	n	Methods	Conclusion or findings
Ijichi et al[82]	3	FDG	(1) SUVmax value of three cHCC-CC cases: 9.9, 12.0, and 13
		-PET	(2) Median SUVmax value of poorly differentiated HCC: 5.7
			(1) 6/11 showed early ring enhancement with progressive enhancement in central portion.
			(2) 5/11 showed a diffuse heterogenous early enhancement.
de Campos et al[83]	11	MRI	Characteristics findings of cHCC-CC: irregular shape and strong rim enhancement during early phase; absence of target appearance on hepatobiliary-phase
Hwang et al[84]	20	MRI

cHCC-CC: Combined hepatocellular-cholangiocarcinoma; MRI: Magnetic resonance imaging; FDG-PET: ¹⁸F-fluorodeoxy glucose positron emission tomography.
