ileokolische Invagination

Ileozökale

Invagination und zweite kleine Dünndarminvagination im linken Oberbauch.

Infant with

abdominal pain and currant jelly stools and peritonitis. AXR supine (left) shows decompressed loops of bowel (presumed jejunum) in the left upper quadrant and multiple dilated loops of bowel (presumed ileum) in the right lower quadrant. AXR upright (right) shows multiple air-fluid levels.The diagnosis was distal small bowel obstruction with the patient going directly to the operating room due to the peritonitis where an ileocolic intussusception was encountered and reduced.

Toddler with

colicky abdominal pain. XR supine (upper left) shows a non-obstructive bowel gas pattern but suggests a soft tissue mass in the right lower quadrant. Transverse US of the right lower quadrant (upper middle) shows a soft tissue mass with a target sign measuring 3 cm in diameter while the longitudinal US (upper right) shows a pseudokidney sign. AP spot image from an air enema (bottom) shows a soft tissue mass being encountered in the cecum.The diagnosis was ileocolic intussusception which was successfully reduced.

Intussuscepted

Meckel diverticulum. Coronal reformatted CT, showed small bowel distention, and ileocolic intussusception with a central core of fat density suggesting an intussuscepted, inverted Meckel diverticulum.

Computed

tomography of complicated Meckel’s diverticulum in adults: a pictorial review. A 39-year-old woman with surgically proven ileal intussusception related to the Meckel’s diverticulum as the lead point. a Intravenous- and oral-enhanced CT scan shows the intussusception of the ileum (arrow) along with its mesentery (asterisk), creating the “target sign.” b Image at a lower level than a demonstrates the invaginated mesenteric fat (arrow), along with thickening of the intussuscepted ileum (arrowhead).
