Koloninvagination

Dünndarminvagination
in der Computertomographie: Axial typische kokardenartige Formation.

Dünndarminvagination
in der Computertomographie. Axial nur in der Bildfolge erkennbar, aber coronar gut sichtbar.

Colocolic
intussusception presenting as gastrointestinal bleeding. Coronal enhanced CT image - again the highly heterogenouns and enhancing intussusceptum and the \"sandwich sign\"

Adult
colocolic intussusception due to colonic mass. Axial CECT showing thickening and enhancement of ascending colon wall (22 mm thickening) with colocolic intussusception.

Retrograde
jejuno-gastric intussuception. Sequential axial CECT sections shows jejunal loop outlined by oral contrast (white arrow) along with its mesentry encroaching into the gastric lumen.

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.

Peutz-Jegers
Syndrome. A reduction with contrast was attempted, which was partially succesfull. During such reduction, you should keep in mind the “rule of threes”. Unsuccesfull reductions are often followed by a surgical intervention.

Peutz-Jegers
Syndrome. Subsequent CT of the abdomen. Axial and coronal reconstructions revealed an intussusception to be responsible for the soft tissue appearance on the conventional radiography. An apparent lead point could not be discerned.

Colocolic
intussusception presenting as gastrointestinal bleeding. Axial non-enhanced CT image - behold the smiley face! made from an intussusceptum and two lymph nodes is the center and the oedematous intussuscipiens at the periphery

Intussusception
of small intestine as complication of Peutz-Jeghers syndrome with surgical correlation. Image revealing a jejunal intussusception appearing target-like in its transverse section (arrow). There are concentric layers of high and low attenuation representing bowel wall and mesenteric fat.

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.

Kurzstreckige
temporäre Invagination des Jejunums bei einem Mann ohne diesbezügliche Symptome. Target-sign.

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.

An ultrasound
showing target sign which is a characteristic finding for intussusception on ultrasound, this ultrasound is for a 3 year old boy with intestinal intussusception. source:Radiopedia.org and case


Adult
colocolic intussusception due to colonic mass. Coronal CECT showing "target sign" in intussusception.
