Summary
A pediatric brain injury case revealed unexpected ascites, likely due to central beta-sympathetic hyperactivity. This condition resolved spontaneously within weeks, highlighting a novel trauma complication.
Area of Science:
- Pediatric Traumatology
- Neurocritical Care
- Gastroenterology
Background:
- Traumatic brain injury (TBI) in pediatric patients can lead to complex systemic complications.
- Ascites, the accumulation of fluid in the peritoneal cavity, is an uncommon finding post-trauma.
Observation:
- An 11-month-old boy sustained a severe TBI with right frontal lobe contusion and bleeding after a fall.
- Ascites developed 6 days post-trauma, confirmed as transudative fluid via CT, with no identified abdominal lesions.
- The ascites resolved spontaneously by day 19 post-trauma.
Findings:
- The ascites was hypothesized to be mediated by beta-sympathetic hyperactivity originating from the central nervous system.
- This suggests a potential link between TBI severity and autonomic nervous system dysregulation affecting fluid balance.
- Sequential echography demonstrated progressive improvement and eventual resolution of the ascites.
Implications:
- This case highlights a rare, potentially overlooked complication of pediatric TBI.
- It underscores the importance of considering central nervous system-mediated autonomic dysfunction in unexplained post-traumatic ascites.
- Further research into the neuro-autonomic pathways involved in post-TBI fluid dysregulation is warranted.
