Intussusception in Adults: The Role of MDCT in the Identification of the Site and Cause of Obstruction.

Unlike pediatric intussusception, intestinal intussusception is infrequent in adults and it is often secondary to a pathological condition. The growing use of Multi-Detector Computed Tomography (MDCT) in abdominal imaging has increased the number of radiological diagnoses of intussusception, even in transient and nonobstructing cases. MDCT is well suited to delineate the presence of the disease and provides valuable information about several features, such as the site of intussusception, the intestinal segments involved, and the extent of the intussuscepted bowel.

Endovascular management of the rectus muscle hematoma.

Purpose: Non-traumatic spontaneous hematoma of the rectus abdominal muscle is not considered a critical condition. Nevertheless, it can be a serious complication in some patients due to continuous and/or consistent bleeding. The most frequent cause of spontaneous rectus muscle hematoma is the anticoagulation therapy.

Esophageal cancer staging: the role of radiology.

In esophageal cancer staging, the radiologic approach is represented by tumor identification, preoperative staging, and re-staging after neoadjuvant therapies. At present, while barium radiography shows a high sensitivity for early and advanced tumors, endoscopy is always necessary for confirmation. CT and MRI are the gold standard for preoperative staging of advanced (T4) esophageal cancer and for evaluation of distant metastasis; however they still show a low sensitivity in the study of possible regional lymph node involvement, in differentiating residual disease and scarring; in particular the esophageal wall cannot be carefully examined.
