Abstract

We present the case of a 37-years old male, who consulted for an extended history of intermittent nausea and vomiting. Laboratory tests showed moderate elevated bilirubin (1.30 mg/dL) and GGT (106 U/L). An abdominal CT scan performed showed a solid 18-centimetres (cm) mass located in the right liver lobe. A biopsy of the lesion was performed, revealing metastastic cells of a well-differentiated neuroendocrine tumour (NET, G3 (Ki-67: 25%). Further study was performed with MRI, and SPECT-CT, showing a 2-cm lesion in the pancreatic tail suggestive of being the primary NET. Chromogranin A levels were high (114.100 ng/ml). In our case, despite the large size of the liver metastasis a full resection of the tumours was achieved.
