Bowel inflammatory presentations on computed tomography in adult patients with severe aplastic anemia during flared inflammatory episodes

Figure 8 Characteristic images of case 7. A-F: Characteristic images of the ileocecal region and the large colon. The ileocecal valve was thickened and stratified (yellow arrow). The distal ileum was thickened and strictured (green arrows) with a large cluster of misty exudative lesions surrounding the cecum and distal ileum, and the proximal small intestine was liquid-filled with multiple gas-liquid levels. From the cecum to the distal descending colon, the mucosa and the villi were hyperdense, with several focally wall-thickened and stratified colonic segments (red arrows) and several inflamed diverticula (blue arrows). An obstructively thickened segment of the sigmoid colon (orange arrows) with prominent paracolonic hypervascular fat stranding was distal to the remarkably distended lumen and paper-thin bowel wall of the sigmoid colon (white arrows); G-I: Reconstructed images of the obstructively thickened sigmoid colon. From the reconstructed images, the obstructively thickened segment of the sigmoid colon (orange arrows) and the proximal distended sigmoid colon (white arrows) were better visualized. The misty exudative lesions and the surrounded cecum and distal ileum were also better visualized (green arrows).
