Case contributed by Dr Abdallah Alqudah

Presentation

Alteration in bowel habit and mass in the right lower abdomen.

Patient Data

Age: 55 years
Gender: Female
CT

There is a heterogeneously enhancing soft tissue mass lesion seen in the right iliac fossa, arising from the mesentery of small bowel. It contains areas of necrosis and foci of calcifications and causes a desmoplastic reaction.

Multiple adjacent ovoid-shaped enhancing regional lymph nodes are also present.

Multiple hypodense lesions seen scattered in the liver; the largest one is seen in segment IVa, concerning for metastases.

Multiple enhancing pathological lymph nodes are seen in the coeliac, preaortic, aortocaval, left and right para-aortic, peripancreatic regions and the mesentery.

Case Discussion

The diagnosis was suggested by the presence of a desmoid reaction in addition to the lab results.  Histology confirms the mass as a well-differentiated neuroendocrine tumour (carcinoid tumour).
