| Research Abstract |
We evaluated the “periportal cancer spread pattern (PCSP)”by using multiplanar reformations of 1-mm slices on multidetector row CT (MDCT). Results show that nine (38%) out of 24 patients with intrahepatic and hilar cholangiocarcinomas were positive for PCSP, wherein those with hilar cholangiocarcinoma especially showed extensive PCSP from the subsegmental level to the extrahepatic periportal area. Regarding extrahepatic cholangiocarcinoma, the posterior hepatic plexuses which run from the periportal area to the right celiac ganglion assume a large role in PCSP detection, whereby MDCT reveals the increased attenuation of fat tissue along the nerve routes.
