Difficulty: EasyPediatric Gastrointestinal Disorders

Match each classic clinical or imaging finding with its corresponding pediatric gastrointestinal diagnosis.

  • "Target sign" on abdominal ultrasoundIntussusception
  • "Double-bubble" sign on abdominal radiographyDuodenal atresia
  • Palpable "olive-like" mass in the right upper quadrantInfantile hypertrophic pyloric stenosis
  • Failure to pass meconium within the first 48 hours of lifeHirschsprung disease
  • Painless lower gastrointestinal bleeding in a toddlerMeckel diverticulum

Answer

The correct pairings are: 'Target sign' with Intussusception; 'Double-bubble' sign with Duodenal atresia; 'Olive-like' mass with Infantile hypertrophic pyloric stenosis; Failure to pass meconium with Hirschsprung disease; and Painless lower GI bleeding with Meckel diverticulum.
Each classic sign uniquely identifies its corresponding pediatric gastrointestinal pathology. Recognizing these pathognomonic buzzwords and their underlying pathophysiology is essential for the rapid diagnosis of pediatric GI emergencies and congenital anomalies.

Step-by-Step Solution

1
Evaluate the first finding: 'Target sign' on ultrasound.
Matches with Intussusception.
The 'target sign' indicates bowel telescoping, which defines intussusception.
2
Evaluate the second finding: 'Double-bubble' sign on X-ray.
Matches with Duodenal atresia.
This sign represents gas trapped in the stomach and proximal duodenum due to congenital atresia.
3
Evaluate the third finding: Palpable 'olive-like' mass.
Matches with Infantile hypertrophic pyloric stenosis.
The hypertrophied pylorus muscle is classically palpable as an 'olive' mass in the right upper quadrant.
4
Evaluate the fourth finding: Failure to pass meconium within 48 hours.
Matches with Hirschsprung disease.
Aganglionosis of the distal colon prevents normal meconium passage in the newborn.
5
Evaluate the fifth finding: Painless lower GI bleeding in a toddler.
Matches with Meckel diverticulum.
Ectopic gastric mucosa in the diverticulum causes mucosal ulceration and subsequent painless bleeding.
