We present a case report of a patient with a suspicious ileal carcinoid tumour. Clinical examination as well as computer tomograghy （CT） scan suggested a tumour. Octeotride scan showed uptake in the same bowel loop reported as pathological in CT. The patient underwent surgery and biopsy which reported Crohn’s disease （CD）. The interest in the case is due to the fact that this is, to the best of our knowledge, the second report of Crohn’sdisease as a cause of false positive octeotride scan. Unfortunately, no somatostatin recptors could be found in the sample, so further studies should be performed.
