Timeline of chest CT and plain radiography findings. a Plain chest radiograph at the time of first admission showing reticular shadowing of both lower lung fields bilaterally. b High-resolution CT (HRCT) image of the chest at the time of first admission showing scattered reticular shadows. c HRCT image of the chest 2 months later showing exacerbation of the ground-glass opacities and thickening of the interlobular septa. d HRCT of the chest at the time of the second admission showing resolution of the ground-glass opacities.

Chest plain radiography revealed reticular shadowing in both lower lung fields (Fig. 1a), and chest CT demonstrated scattered reticular shadows (Fig. 1b). Chest CT demonstrated thickening of the interlobular septa and panlobular ground-glass opacities in both lungs (Fig. 1c). On admission, repeat chest CT was performed, demonstrating resolution of the previously observed pulmonary shadowing (Fig. 1d).
Timeline of abdominal CT and plain radiography findings. a Plain abdominal radiograph at the time of first admission showing linear calcification in the ascending colon (arrowheads). b CT of the abdomen at the time of first admission showing thickening of the ascending colon and calcification of the mesenteric vessels (arrowheads). The small intestines are seen to be dilated (arrows). c CT of the abdomen 2 months later showing thickening of the bowel walls from the ascending to the transverse colon and calcification of the mesenteric veins (arrowheads). The small intestine no longer appears dilated.

Abdominal plain radiography revealed linear calcification in the ascending colon (Fig. 2a). No findings suggesting portal hypertension were observed (Fig. 2b). Abdominal CT again revealed bowel wall thickening from the ascending to the transverse colon; however, the small intestine was no longer seen to be dilated (Fig. 2c).
Representative colonoscopy image at the time of first admission demonstrating the presence of dark purple edematous mucosa; this was seen to extend from the transverse colon to the cecum.

Colonoscopy showed dark purple edematous sclerotic mucosa from the transverse colon to the cecum (Fig. 3).
Representative microscopic examination image at the time of first admission demonstrating proliferation of collagen fibers and moderate hyalinization adjacent to capillaries.

We observed moderate hyalinization adjacent to capillaries (Fig. 4).
