Match each classic clinical presentation and associated diagnostic imaging finding with the most appropriate pediatric gastrointestinal diagnosis.
- A neonate evaluated on day two of life for recurrent green-colored vomiting; abdominal radiography shows a 'double bubble' sign.Duodenal atresia
- A one-month-old baby presenting with forceful, milk-colored emesis after feedings; upper gastrointestinal imaging reveals a 'string sign'.Hypertrophic pyloric stenosis
- A previously well three-day-old newborn who suddenly develops dark green vomiting; fluoroscopy demonstrates a 'corkscrew' duodenal configuration.Midgut volvulus
- An older infant in late infancy with episodes of severe crying, drawing up the legs, and bloody stools; sonography reveals a 'target sign'.Intussusception
Answer
The presentations correctly map to their diagnoses: the 'double bubble' sign indicates duodenal atresia; the 'string sign' indicates hypertrophic pyloric stenosis; the 'corkscrew' configuration indicates midgut volvulus; and the 'target sign' indicates intussusception.
Each clinical presentation contains a highly specific, pathognomonic imaging buzzword that directly points to a distinct pediatric gastrointestinal pathology. Recognizing these hallmark signs (double bubble, string sign, corkscrew, target sign) is critical for accurate diagnosis and prompt management.
