How would you describe intussusception on CT?
Manifestations of Intussusception It typically appears as a targetlike or sausage-shaped mass, depending on the axial projection (,9). Distinct anatomic features, including the entering wall, mesenteric fat and vessels, returning wall, and intraluminal space, can be clearly seen at CT (,Figs 1, ,2).
What is the sonographic appearance of intussusception?
An intussusception presents as a round mass with a target bowel-in-bowel appearance in the transverse plane, the classic finding on ultrasound (Figure 2). The features are unique in that they consist of concentric rings of bowel wall and internal hyperechoic mesenteric fat.
What is ILEO Ileocolic intussusception?
Ileocolic intussusceptions are defined as those in which ileum prolapses through the ileo-caecal valve into the colon, and these constitute 15% of all intussusceptions. The ileo-caecal valve and the appendix preserve their normal anatomical position, and the organic lesion is usually in the ileum [8.
What is Pneumatosis of the colon?
INTRODUCTION. Pneumatosis intestinalis (PI) refers to the presence of gas within the wall of the small or large intestine. Intramural gas can also affect the stomach, but this condition is referred to as gastric pneumatosis [1].
Is intussusception palpable?
The hallmark physical findings in intussusception are a right hypochondrium sausage-shaped mass and emptiness in the right lower quadrant (Dance sign). This mass is hard to detect and is best palpated between spasms of colic, when the infant is quiet.
What is a sausage shaped mass?
Further, a red, mucus or jelly-like stool is usually seen with intussusception. Physical examination may reveal a “sausage-shaped” mass felt upon palpation of the abdomen. Symptoms of intussusception may resemble other conditions or medical problems.
What is Enteroenteric intussusception?
Enteroenteric intussusceptions are much more common than gastric intussusception and result when one loop of small bowel invaginates into the adjacent small bowel. They can be categorized as duodenojejunal, jejunojejunal, or jejunoileal.
What is a lead point?
In some cases in adults, the telescoping is caused by an abnormal growth in the intestine, such as a polyp or a tumor (called a lead point). The normal wavelike contractions of the intestine grab this lead point and pull it and the lining of the intestine into the bowel ahead of it.
How do you know if your baby has intussusception?
The first sign of intussusception in an otherwise healthy infant may be sudden, loud crying caused by abdominal pain. Infants who have abdominal pain may pull their knees to their chests when they cry. The pain of intussusception comes and goes, usually every 15 to 20 minutes at first.
Why is there abdominal pain in intussusception?
Tissue death can lead to a tear (perforation) in the intestinal wall, which can cause an infection of the lining of the abdominal cavity (peritonitis). Peritonitis is a life-threatening condition that requires immediate medical attention. Signs and symptoms of peritonitis include: Abdominal pain.
