Please pair the following pediatric gastrointestinal conditions with their most characteristic radiological finding on diagnostic imaging.
- Midgut volvulusUpper gastrointestinal contrast series demonstrating a 'corkscrew' pattern of the duodenum
- IntussusceptionAbdominal ultrasound revealing a concentric 'target' or 'donut' sign in the right upper quadrant
- Hypertrophic pyloric stenosisAbdominal ultrasound demonstrating a thickened muscle layer greater than 4 mm and elongated canal
- Duodenal atresiaPlain abdominal radiograph showing a 'double bubble' sign with an absence of distal bowel gas
- Hirschsprung diseaseContrast enema depicting a clear transition zone between a narrowed rectosigmoid and dilated proximal colon
Answer
Midgut volvulus pairs with the 'corkscrew' pattern on upper GI series. Intussusception pairs with the 'target' sign on ultrasound. Hypertrophic pyloric stenosis pairs with the thickened muscle on ultrasound. Duodenal atresia pairs with the 'double bubble' sign on radiograph. Hirschsprung disease pairs with the transition zone on contrast enema.
Each pediatric gastrointestinal disorder produces a distinct structural abnormality that is best visualized using specific imaging modalities. Recognizing these classic radiological signs is crucial for prompt diagnosis and surgical or medical management.
