TB infection and the chest X-ray findings. The abdominal scan did not reveal any significant findings apart from the presence of edema at the rectum (Figure 1).
The gallium-67 scintigraphy revealed persistent diffuse concentration of the gallium in the ascending colon at 24-hour imaging. Gallium-67 excreted into the bowel and laxatives are essential for the differential diagnosis between true positive increased bowel activity and false positive uptake due to bowel content.

The gallium-67 scintigraphy revealed persistent diffuse concentration of the gallium in the ascending colon (Figure 2) at 24-hour imaging, in discordance with the colonoscopy (no signs of active inflammation at the ascending colon).
After the use of laxatives, the gallium-67 diffuse uptake of the ascending colon not only remained stable but rather strengthened without any topographic change at the repeated 72-hour imaging, indicating active inflammation.

One month later, she was reevaluated with a gallium-67 scintigraphy, which was notably different, with total absence of gallium-67 concentration in the ascending colon (Figure 4).
