case_images: (a) Initial MRI scans of the liver (T2, T1C+ and DWI) before surgery showing the extent of liver metastasis of the VIPoma. Multiple lesions can be seen in liver segments II, IVa, VII and VIII (yellow arrows). Lesions are best detectable in DWI sequences. (b) Postoperative MRI scans during surveillance for 6 months. The images show resection defects and remnants after RFA without any indication of tumour recurrence.

case_images: Magnetic resonance imaging (MRI) scans showing the extent of the liver metastasis are presented in Figure 1(a). The patient was still in good health, and MRI showed no change (Figure 1(b)).
case_images: Representative images of immunohistochemical staining of the tumour resected from the pancreatic tail (immunoperoxidase on paraffin sections). Strong expression of (a) chromogranin and (b) synaptophysin. The Ki67 labelling index was 6% ((c) original magnification x400; (d) original magnification x200).

case_images: Interestingly, the resected tumour showed no signs of regression in the histopathological work-up (Figure 2).
