Summary
A new ultrasound finding, gallbladder hyperechogenicities, may indicate advanced neonatal necrotizing enterocolitis (NEC) in newborns. This pattern suggests disease spread to the perivesicular space, potentially via the lesser sac.
Area of Science:
- Neonatal imaging
- Pediatric gastroenterology
- Abdominal ultrasonography
Background:
- Neonatal necrotizing enterocolitis (NEC) is a serious gastrointestinal emergency.
- Early detection of NEC complications is crucial for timely intervention.
- Current sonographic markers for NEC may not capture all disease extensions.
Purpose of the Study:
- To describe a novel sonographic pattern associated with NEC.
- To investigate the potential significance of pericholecystic hyperechogenicities in NEC.
- To explore the anatomical pathways for disease extension in NEC.
Main Methods:
- Retrospective review of 5 neonatal cases with NEC.
- Detailed sonographic analysis focusing on the gallbladder and surrounding structures.
- Correlation of imaging findings with clinical data and outcomes.
Main Results:
- A consistent pattern of hyperechogenicities around the gallbladder was observed in NEC patients.
- This finding is hypothesized to represent extension of NEC to the perivesicular space.
- Possible routes of spread include the lesser sac and/or right gutter, potentially due to foamy infiltrates.
Conclusions:
- Pericholecystic hyperechogenicities represent a potential new sonographic sign of NEC.
- This sign may indicate advanced NEC with local spread.
- Further studies are warranted to confirm the diagnostic value of this finding.
