case_images: CECT revealed large hypodense enhancing lesion involving the right lobe of the liver and FDG-PET-CT showed them to be hypermetabolic, suggesting to be of a metastatic disease [Figure 1a-c].
case_images: No abnormal rejection activity index accumulation noted in liver (a and b; anterior and posterior images, respectively)

case_images: I-131 whole body scan did not show any abnormal concentration in the liver [Figure 2a and b; anterior and posterior images, respectively]. In view of normal
case_images: The histopathology reveals neuroendocrine tumor cells (a and b), immunopositive for chromogranin and synaptophysin (c and d, respectively)

case_images: To confirm the diagnosis, a repeat liver biopsy was planned at our institute. The histopathology revealed neuroendocrine tumor (NET) cells [Figure 3a and b] which were immunopositive for chromogranin and synaptophysin [Figure 3c and d, respectively].
case_images: 68-Ga-DOTANOC positron emission tomography-computed tomography shows somatostatin receptor expressing tumor in both lobes of liver with extensive skeletal metastasis (a-c; transaxial computed tomography, positron emission tomography-computed tomography and maximum intensity projection images, respectively)
