- An abnormally increased uptake of the bone-seeking agent is rarely
observed in structures other than the bone and urinary track on bone scintigraphy.
The general etiologies of soft tissue uptake can be explained by heterotopic
ossification or dystrophic and metastatic calcification. We report a
case of serendipitous visualization of the entire colon on bone scintigraphy.
Diffuse colonic uptake was detected on the whole-body bone scan in a patient
with biopsy-proven sigmoid colon cancer. Additional imaging studies clearly
showed direct bladder invasion of the sigmoid colon cancer. Imaging findings
with a brief review of the literature are presented in this article.
Key Words: bone scan, extraskeletal uptake, bowel visualization,
