title: Lung or liver: An imaging dilemma on Tc-99m macroaggregated albumin lung perfusion scintigraphy.
abstract: We present a 10-year-old boy having the bronchiectasis who was subjected to lung perfusion scintigraphy before lung resection surgery to assess the lung parenchymal function. It revealed unusual tracer distribution in right upper body that was mimicking to be liver. It was unusual unless there were some shunts bypassing the lung uptake or faulty radiopharmaceutical preparation. However by bringing down the image window, it became clear that radiopharmaceutical distribution was in thorax only correlating with lung uptake, and not in the liver. Corresponding X-ray chest and computed tomography thorax demonstrated multiple cystic lesions in left lung parenchyma.
