Needle tract implantation of hepatocellular carcinoma (HCC) is a rare complication of percutaneous biopsy, and it is largely associated with end-cutting needles or aspiration biopsy. The CT findings that have been reported include oval or round soft tissue nodules with persistent contrast enhancement along the needle tract, mostly in the subcutaneous tissue or the intercostal muscle layers. In this report, we describe a case of needle tract implantation of HCC after US-guided percutaneous biopsy with an 18G tru-cut needle. (Korean J Hepatol 2006;12:439-443)
