A “false positive” octreoscan in ileal Crohn’s disease

Figure 1 CT-scan showing thickening of the distal ileum (long arrow) with an adjacent solid mass (short arrow), suggesting a carcinoid tumour.

Figure 2 Octeotride-SPECT images showing pathological uptake in the ileal thickened loop at CT-scan.

Figure 3 CD showing marked transmural inflammatory changes (involving the walls of veins and arteries): edema, lymphatic dilatation, hyperplasia of the muscularis mucosae, fibrosis (“obliterative muscularization”), and epithelioid granuloma.
