Insights
A rare congenital anomaly, a pyloric duplication cyst, was identified in a newborn. Surgical resection was successful, and the infant is recovering well.
Area of Science:
- Pediatric Surgery
- Congenital Anomalies
- Gastrointestinal Development
Background:
- Enteric duplication cysts (EDCs) are rare congenital gastrointestinal malformations.
- Most EDCs occur in the ileum; gastroduodenal EDCs are exceptionally rare, accounting for 5-7% of cases.
Observation:
- A 3-hour-old male infant presented with a cystic mass identified prenatally.
- Postnatal ultrasound revealed a mass with a probable trilaminar wall in the upper abdomen.
Findings:
- Surgical exploration confirmed the diagnosis of a pyloric duplication cyst.
- Histopathologic examination post-resection validated the diagnosis.
Implications:
- This case highlights the rarity of gastroduodenal enteric duplication cysts, specifically in the pylorus.
- Successful surgical management and recovery in neonates with this condition are possible.
Abstract:
An enteric duplication cyst (EDC) is a rare congenital anomaly. Although EDCs can occur at any point throughout the gastrointestinal tract, they are most commonly reported in the ileum and only around 5-7% are of gastroduodenal origin. We report a case of a pyloric duplication cyst in a 3 hour old male with prenatal ultrasound showing a cystic mass. The patient had an abdominal ultrasound after birth that showed a mass with probable trilaminar wall. The diagnosis of pyloric duplication cyst was made in surgery and confirmed with histopathologic examination following resection. The patient is doing well with appropriate weight gain at follow-up appointments.
