Review Case Reports
US and CT diagnosis of complete cecocolic intussusception caused by an appendiceal mucocele.
Appendiceal mucoceles are found in only 0.2-0.3% of all appendectomy materials. Colocolic intussusception of the appendix is also very uncommon. ⋯ The full diagnosis was made preoperatively by ultrasound and confirmed by helical CT by means of unequivocal signs of intussusception associated with a very suggestive "cup-and-ball" aspect of the mucocele induced by a global mucinous cystadenoma of the appendix. A brief review of the available literature on mucocele is given.

Blunt traumatic aortic injuries are a major concern in the settings of high-speed deceleration accidents, since they are associated with a very high mortality rate; however, with prompt diagnosis and surgery, 70% of the patients with a blunt aortic lesion who reach the hospital alive will survive. This statement challenges the emergency radiologist in charge to evaluate the admission radiological survey in a severe chest trauma patient. ⋯ In unstable patients, trans-esophageal echography (TEE) plays a major diagnostic role. Knowledge of advantages and pitfalls of these imaging techniques, as reviewed in this article, will help the emergency radiologist to choose the appropriate algorithm in the diagnosis of traumatic aortic injury, for each trauma patient.
