Successful resection of localized intestinal lymphangiectasia post-Fontan: role of (99m)technetium-dextran scintigraphy.

Intestinal lymphangiectasia is a well-recognized complication of the Fontan procedure, occurring in up to 24% of patients. Because of the loss of chylous fluid into the gut lumen, protein-losing enteropathy results as well as lymphopenia and hypogammaglobulinaemia. In some cases, dilated lymphatics in the intestinal serosa or mesentery also rupture, causing chylous ascites.

Abnormal uptake of Technetium-99 m hydroxymethylene diphosphonate in the liver.

Diffuse liver uptake on bone scintigraphy is a rare occurrence with only a few reports in the literature. A case of diffusely increased uptake in a patient with acute hepatitis is presented.

Extrarenal uptake of 99mTc-DTPA at the site of bone marrow biopsy.

Unexpected iliac uptake of 99mTc-DTPA was noted in a 10-year old female referred for evaluation of renal function prior to receiving chemotherapy for relapsed acute lymphocytic leukemia. This scan finding corresponded to the site of a bone marrow biopsy performed five days earlier. X-ray of the area revealed no abnormality.
