ABSTRACT
Objective To analyse the multi-slice spiral CT(MSCT) findings of small cholangiocarcinoma of common bile duct.Methods 15 cases with pathologically verified small cholangiocarcinoma of common bile duct were undergone unenhanced and three-phase contrast-enhanced MSCT scan.The entire morphologic changes of common bile duct were analysed with curved planar reformation(CPR).Results The attenuation of tumor relative to pancreas was iso-density in all cases at plain CT scan,hypo-density in 10 cases,iso-density in 3 cases and hyper-density in 2 cases at arterial phase,hypo-density in 1 case,iso-density in 3 cases and hyper-density in 11 cases at portal phase,iso-density in 5 caaes and hyper-density in 10 cases at delayed phase.The focal wall thickening of common bile duct appeared as circular or eccentric in 13 cases,intraluminal nodule in 2 cases,common bile duct was narrowing sharply in 11 cases and ending abruptly in 4 cases at obstructive level.Conclusion The small cholangiocarcinoma of common bile duct is of certain characteristics at unenhanced and three-phase contrast-enhanced CT scan.
