A 77-year-old male patient with given history of cancer colon with hepatic metastatic focal lesion under treatment. PET CT was done to evaluate therapeutic response. a Pre and b post treatment axial CT images of the liver revealed mild size progression of the deep parenchymal hypodense hepatic focal lesion seen at segment VI/VII in the current study measures 3 cm in diameter (red arrow) compared to 2.6 cm in the previous study (white arrow) this assume progressive course of the disease. c Pre and d post treatment axial PET images of the liver and e pre and f post treatment axial fused PET/CT images of the liver revealed mild size progression of the deep parenchymal hypodense hepatic focal lesion seen at segment VI/VII yet showed partial metabolic response with SUVmax 3.5 in the current study compared to SUVmax 4.5 in the previous study; so the patient actually running regressive course and this size progression attributed to breaking down
