Intraluminal duodenal diverticulum associated with trisomy 21

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Medical Imaging

Background:

• Intraluminal duodenal diverticulum is a rare congenital anomaly.
• Its exact cause is debated, but likely involves a congenital web or diaphragm.
• It can lead to intermittent duodenal obstruction.

Observation:

• The classic diagnostic sign is a "wind sock"-like barium-filled structure within the duodenum.
• This structure is typically surrounded by a radiolucent halo on imaging.
• An association with trisomy 21 has been noted.

Findings:

• The study describes the characteristic radiologic appearance of intraluminal duodenal diverticulum.
• It highlights the "wind sock" sign as diagnostic.
• The potential link to trisomy 21 is mentioned.

Implications:

• Understanding the pathogenesis aids in diagnosis and management.
• Radiologists should be aware of the classic imaging findings.
• The association with trisomy 21 may warrant genetic screening in affected infants.
