Figure 8:

Images in a 68-year-old woman with relapsed small cell lung cancer (SCLC) after chemoradiotherapy for limited stage SCLC. The patient was treated with nivolumab and ipilimumab. (A, B) Axial (A) and coronal (B) CT images obtained 7 weeks after immune checkpoint inhibitor (ICI) therapy. Abdominal CT scans demonstrate diffuse wall thickening and increased mucosal enhancement of the ascending and transverse colon (arrows in A) and a fluid-filled lumen in the ascending colon (arrow in B), representing a characteristic appearance of ICI-related pancolitis.
