Serendipity in scintigraphic gastrointestinal bleeding studies

Clin Nucl Med. 1983 Sep;8(9):396-9. doi: 10.1097/00003072-198309000-00002.


A retrospective review of 80 scintigraphic bleeding studies performed with Tc-99m sulfur colloid or Tc-99m labeled red blood cells showed five cases where there were abnormal findings not related to bleeding. In some cases, the abnormalities were initially confused with bleeding or could obscure an area of bleeding, while in other cases, the abnormalities represented additional clinical information. These included bone marrow replacement related to tumor and radiation therapy, hyperemia related to a uterine leiomyoma and a diverticular abscess, and a dilated abdominal aorta (aneurysm). Recognition of such abnormalities should prevent an erroneous diagnosis and the additional information may be of clinical value.
