Excerpt
Radionuclide-labeled leukocyte imaging is a useful method for assessing various aspects of inflammatory bowel disease. The accuracy of Tc-99m HMPAO–labeled leukocyte imaging has exceeded that of conventional radiologic and endoscopic techniques. The spleen, liver, bone marrow, kidneys, bowel, bladder, and major blood vessels are normally visualized on tagged leukocyte scintigraphy. The time to image Tc-99m HMPAO–labeled leukocytes depends, in part, on the type and location of possible infection. Four-hour imaging helps to differentiate physiologic early hepatic uptake from abnormally increased uptake seen with sepsis. Focal collections of inflamed peritoneal fluid or sites of focal bowel inflammation can be mistaken for abscess. The authors report excessive compensatory hypertrophy of the left lobe of the liver on ultrasonography, computed tomography, and labeled leukocyte scintigraphy. Scintigraphic findings could be confused with abdominal infection with possible inflammatory bowel disease.
