Small bowel infarcts in Degos disease.

Degos disease is a rare idiopathic vasculopathy with multisystem involvement. We present a previously healthy 40-year-old woman who developed spontaneous small bowel infarctions and perforations 17 months after presentation with characteristic skin lesions. The abdominal CT findings of Degos disease, which have not been previously depicted in the radiology literature, are discussed.

An update on imaging of colorectal cancer.

Screening of asymptomatic average-risk patients for presence of colon cancer and early detection in precursor stages is of great interest to general population. Comprehensive evaluation of symptomatic or high-risk patients represents another important clinical focus. Available techniques for total colon imaging, rectal cancer staging and the role of positron emission tomography are discussed.
