Intestinal uptake of (99m)Tc-MDP: a case report of protein-losing enteropathy correlated with pathology findings from autopsy.
We present a case of a 60-year-old man with a history of severe hypoproteinemia and constitutional syndrome, suspected to have protein-losing enteropathy (PLE). Bone scintigraphy ((99m)Tc-MDP) performed to rule out the presence of bone metastases incidentally showed abnormal uptake in abdominal soft tissue. The patient unexpectedly died of heart failure, and autopsy revealed microscopic alterations consistent with PLE exclusively in the right colon, corresponding to the area of abnormal uptake. Few similar cases have been published, but none of them reported correlative pathological findings affecting the area of abnormal tracer uptake. In this case of PLE, (99m)Tc-MDP scintigraphy was a useful imaging method for localizing the site of protein loss, showing a focal area of alteration in the right colon. This finding could also have been of great help in case that surgery had been finally performed to control the protein loss.
