Intrabiliary growth of colorectal liver metastasis: spectrum of imaging findings and implications for surgical management.
OBJECTIVE
The propensity for colorectal liver metastasis to invade the biliary tree is increasingly recognized, placing particular emphasis on the risk of postoperative recurrence. This article illustrates the spectrum of imaging findings when colorectal metastasis invades the biliary tree.


CONCLUSIONS
Knowledge of the imaging features of intrabiliary invasion by colorectal liver metastasis improves the quality of preoperative staging and is crucial in an era in which nonanatomic wedge resection and radiofrequency ablation are routinely performed.
