    Notes: Abstract Carcinoid tumors are rare neuroendocrine neoplasms that belong to a more general category of tumor called the APUDomas. Ninety percent of carcinoid tumors are located in the gastrointestinal tract. Abdominal carcinoid tumors are categorized according to the division of the primitive gut from which they arise. Carcinoid tumors originating from the foregut develop in the gastric wall, duodenum, and pancreas; those originating from the midgut develop from the small bowel, appendix, and right colon; and those originating from the hindgut develop from the transverse or left colon or from the rectum. This report illustrates the computed tomographic appearance of primary and metastatic carcinoid tumors of the abdomen. Among the different organs that may be involved by metastases from carcinoid tumor, special emphasis is placed on the liver.

    Notes: Abstract. Because of improvement in survival rate of patients with abdominal cancer, gastrointestinal complications following external radiation therapy are becoming more frequent. Thus, an increased number of patients are commonly investigated with imaging because of suspected radiation-induced injury of the gastrointestinal tract. This pictorial review highlights the spectrum of CT and barium study manifestations of radiation-induced injury of the gastrointestinal tract. The major role of CT in the evaluation and management of patients with radiation injury of the gastrointestinal tract is highlighted. Emphasis is placed on CT imaging signs that may help in distinguishing between radiation-induced injury and recurrent disease.

    Notes: Abstract. We report a case of venous rupture complicating percutaneous transluminal angioplasty (PTA) applied on a failed dialysis vascular access (VA) in a patient on chronic steroid therapy. This complication resulted in a rapidly growing hematoma which was successfully controlled by a prolonged reinflation of the balloon catheter at the angioplasty site. The absence of oversizing of the balloon catheter and the low inflation pressure at which the perforation occurred suggest a vessel fragility which was probably induced by a long-standing steroid therapy. In dialysis patients in whom steroid therapy does not represent an infrequent therapeutic modality, this potential risk of vascular rupture should be carefully weighted while treating VA stenoses with the use of PTA.
