Abstract
We reported 99m-Tc phytate accumulation in the pyelocalyceal system of the kidney in the lymphoscintigraphic images of a 3.5
months-old male infant with chylous ascites, which was mistaken with the site of lymph leakage. SPECT/CT localized activity
in the para-aortic region to the renal pelvis and on delayed images, this was disappeared. Our case illustrates the added value
of SPECT/CT for the differentiation of possible false-positive findings in lymphoscintigraphy.
