Abdominal imaging
-
We report a case of an extensive intermittent sigmoidorectal intussusception due to an adenocarcinoma of the rectum in an adult. Abdominal multislice computed tomography with two-dimensional multiplanar reformatted images and three-dimensional volume rendering rapidly established the diagnosis preoperatively. The intussusception was confirmed by surgery.

Magnetic resonance angiography (MRA) has been used to image abdominal vessels less frequently than renal arteries. Until the use of fast contrast-enhanced (CE) techniques, an important limitation was the acquisition time of phase-contrast or time-of-flight imaging and, consequently, the creation of motion artifacts. Recent advances in MRA technology have shortened acquisition times, so it is now possible to obtain successive images in the arterial and then the portal phase. ⋯ CE-MRA is superior to DSA for the simultaneous exploration of the aorta, renal arteries, and iliac arteries, thereby providing a panoramic view of abdominal vascular involvement. MRA can be coupled with measurements of flow. With this functional approach, MRA is the only modality that can completely assess vascular diseases of the abdomen.

Case Reports
Inverted Meckel's diverticulum as a leading point for ileoileal intussusception in an adult: case report.
Intussusception due to an inverted Meckel's diverticulum is considered a rare occurrence. We present a case of a 37-year-old male with anemia and melena due to an inverted Meckel's diverticulum at the base of an ileoileal intussusception. To our knowledge, this is the first case in which small bowel enema, computed tomography, and magnetic resonance imaging showed the pathology.
