Giant Liver Hemangioma Mimicking a Hydronephrotic Kidney on 99mTc-DTPA Scintigraphy

We report a case of a 56-year-old woman who underwent Tc-DTPA renal scintigraphy for the evaluation of a right pelviureteric junction calculi, which incidentally showed radiotracer uptake in a giant liver hemangioma. The initial scintigraphic images showed a large lobulated lesion with peripheral uptake of radiotracer at the right abdominal region, resembling a large hydronephrotic kidney. However, the pattern of progression of the radiotracer, coupled with the clinical history and available corresponding radiologic images, confirmed the uptake to be that of a giant liver hemangioma.
