Vedolizumab-associated diffuse interstitial lung disease in patients with ulcerative colitis: A case report

Figure 1 High-resolution computed tomography of the patient before and after vedolizumab administration. A and B: The lung window of the patient in the high-resolution computed tomography (HRCT) before vedolizumab administration was basically normal except for some scattered miliary nodules and localized emphysema; C and D: the lung window of the patient in the HRCT after two doses of vedolizumab administration showed the new-onset severe diffuse infiltrates, interlobular thickening and fibrosis.
