The Role of Computed Tomography in the Acute Presentation of Colorectal Cancer

Patients affected by Colorectal cancer (CRC) can present acutely in a setting of occlusion, perforation, and lower gastrointestinal hemorrhage, which can all be life-threatening conditions. Traditional radiology is not sufficient for a complete clinical assessment. Computer Tomography (CT) is the most accurate diagnostic tool to evaluate the TNM staging, tumor side and potential complications. In stable patients without suspected perforation and with caution in occlusion, also Contrast Tomography Colo(CTC) can be useful.
