There is an avidly enhancing ovoid shaped lesion in the small bowel mesentery in the right iliac fossa measuring 5 cm in length. A number of similarly enhancing lymph nodes are noted more proximally along the draining vascular pedicle. There is indrawing of distal small bowel loops around the lesion. Mural thickening, oedema and hyperenhancement of these small bowel loops is present. The proximal small bowel loops and the large bowel appear normal. On the post-contrast imaging, some target-shaped liver lesions can be appreciated but the diffusion weighted series confirms the presence of innumerable restricted lesions within the liver, as well as markedly restricted diffusion of the mesenteric mass.
Overall, the appearances are highly suggestive of a small bowel neuroendocrine metastatic (carcinoid) lesion with multiple liver metastases. The small bowel appearances are likely secondary to congestion and a degree of ischaemia secondary to vascular compression by the mesenteric mass.
