RESUMO
BACKGROUND: For many years, peritoneal carcinomatosis (PC) entitled poor prognosis until the development of the cytoreductive surgery technique associated with hyperthermic intraperitoneal chemotherapy. Imaging of peritoneal carcinomatosis plays an essential role in the diagnosis and management of the patients being considered for cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC). MAIN BODY: The key role of imaging in patients with peritoneal malignancy is to aid surgical decision making. A standardized peritoneal magnetic resonance (MR) imaging protocol, including T2-weighted fat suppressed, diffusion-weighted and gadolinium-enhanced sequences, allows to detect small peritoneal tumours that are often missed on other imaging. A systematic approach to MR imaging and a close collaboration between the radiologist and the oncologic surgeon are key elements for an accurate evaluation of candidate patients for CRS and HIPEC. CONCLUSION: MR imaging provides a powerful tool for accurate preoperative imaging in patients considered for curative surgery and assists the surgeon in evaluating patients for CRS and HIPEC.

Macroscopic intrabiliary growth of liver metastases from colonic adenocarcinoma mimicking cholangiocarcinoma, a pattern of intrahepatic spread easily confused with primary neoplasia of the biliary tract, is extremely infrequent. Resection of liver metastases has a better prognosis than that of primary neoplasia of the biliary tract. We report a case of metastasis from adenocarcinoma of the colon that presented as a Klatskin tumor. The definitive diagnosis was established by immunostaining.
