A chest radiograph taken at admission demonstrates whitish patch consolidations on the right upper lung field suggesting pulmonary tuberculosis. The right middle and lower lung fields are also involved with patch consolidations but show much less whitish patches than those of the right upper lung field. Contrasting to the right lung field, the left lung field does not show abnormal findings. There are no vascular abnormalities and no bony thorax abnormalities.

A 74-year-old man was diagnosed with pulmonary tuberculosis via an abnormal chest X-ray and acid fast bacilli sputum smear (fig. 1).
a Sigmoidoscopy demonstrates multiple whitish to yellowish plaques, 5 to 8 mm in size. Many whitish to yellowish plaques are aggregated with much exudate and some fresh blood or scattered on the whole sigmoid colon. Multiple hyperemic erosive lesions are also scattered on the whole sigmoid colon with edematous mucosa. b Sigmoidoscopy, after 2 weeks of metronidazole treatment, shows that the multiple whitish to yellowish plaques and accompanied small erosions, responsible for bleeding, have disappeared completely. Pinkish mucosa with fine normal vascular patterns, which is not observed in a due to edema, is observed.

Sigmoidoscopy revealed multiple yellowish plaque lesions from the rectum to the sigmoid colon (fig. 2a), and mucosal biopsy from the sigmoid colon showed small collections of neutrophils between crypts at the summit of the mucosa with tufts of damaged surface epithelium (fig. 3). Follow-up sigmoidoscopy did not show any evidence of PMC (fig. 2b).
