Lebermetastasen neuroendokriner Tumoren

Appendiceal

metastatic neuroendocrine tumour. Coronal reconstructed CT image, acquired after contrast administration, shows the dilated and thickened appendix, with associated periappendiceal stranding. A heterogeneous, enhancing liver lesion is also present, with coarse calcifications.

Appendiceal

metastatic neuroendocrine tumour. Coronal contrast-enhanced reformatted CT shows a nodular soft tissue enhancing mass, located near the root of the mesentery. This lesion contained small calcifications (not shown). Two liver lesions are seen.

Appendiceal

metastatic neuroendocrine tumour. MRI (T2 weighted, T1 pre-contrast, T1 post-gadolinium in arterial and portal phases) show a heterogeneous, enhancing liver mass with low T1 signal and intermediate T2 signal.

Appendiceal

metastatic neuroendocrine tumour. Ocreotid labelled scintigraphy (ocreoscan), performed after appendicectomy, shows abnormal uptake in the liver, corresponding to the two liver lesions seen on CT, and on the nodular mesenteric lesion, confirming the diagnosis.
