Abstract

Colorectal cancer is a major cause of morbidity and mortality in Western countries. Computed tomography (CT) colonography and conventional colonoscopy are the procedures of choice for the diagnosis. However, sonography, being the first imaging study in patients with aspecific abdominal symptoms, may detect unexpected abdominal tumors. The main sonographic features of colorectal cancer are a short segment with bowel wall thickening or a focal mass of the colon, usually with hypoechoic echo pattern and with irregular margins. The detection of these ultrasonographic signs can lead to prompt appropriate investigations and speedup the diagnostic process.
