Antiseptic-Mediated Colloid Labeling as a Potential Source of Abnormal Liver and Spleen Uptake with ^99mTc-Dimercaptosuccinic Acid

(A and B) Anterior (A) and posterior (B) ^99mTc-DMSA images obtained in a 20-mo-old child showing a small left kidney with probable areas of superior and inferior pole scarring. A dromedary hump is also seen on the left kidney, and is most consistent with an anatomic variant based on correlation with ultrasound. (C and D) Anterior (C) and posterior (D) scintigraphic images obtained in the same patient at 13 y old, showing a similar appearing small left kidney, but now with mild diffuse radiotracer activity throughout the liver and spleen.
