Terminal ileum carcinoid tumor

Case contributed by Dr Maxime St-Amant

Presentation

Acute abdominal pain

Patient Data

Age: 55
Gender: Male
Modality: CT

The main finding is an heterogeneous mass involving the terminal ileum with slight focal upstream dilatation of the bowel, highly suggestive of a carcinoid tumor. Moreover, there is some fat stranding involving the root of the mesentery as well as small lymph nodes. Mesenteric metastasis are not entirely excluded; fortuitous  mesenteric panniculitis seems more probable.

Noncaracterisable hepatic hypodensities are seen, as well as other less relevant findings.

Case Discussion

The histopathological diagnosis confirmed the carcinoid tumor. Mesenteric panniculitis is classically described in the differential diagnosis of carcinoid tumor, which can present as a mesenteric desmoplastic reaction with lymphadenopathy. However, in this case, mesenteric panniculitis was considered more probable.
