Computed tomography of abdominal carcinoid tumour.

Ten patients with pathologically proven abdominal carcinoid tumour were assessed by computed tomography (CT). Post-mortem examination correlation was obtained in two cases. Computed tomography demonstrated the extent of intra-abdominal tumour well and is, therefore, a useful staging technique for patients being treated with adjuvant therapy. The appearances of metastatic carcinoid within the mesentery on CT are characteristic and can enable a pre-operative diagnosis to be made.
