Hepatic necrosis masquerading as trauma

B Anderson1, A Cluroe, D Duncan

  • 1Department of Intensive Care, PICU, Children's Health South Pacific, Park Road, Auckland, New Zealand.

Summary

A child experienced liver dysfunction after a skull fracture, initially suspected as trauma. However, acetaminophen toxicity, exacerbated by ischemic hepatitis, was the actual cause of liver necrosis.

Area of Science:

  • Pediatric Medicine
  • Hepatology
  • Trauma Surgery

Background:

  • Skull fractures can lead to complex medical presentations.
  • Liver dysfunction following trauma requires careful differential diagnosis.
  • Acetaminophen (paracetamol) is a common analgesic with potential hepatotoxicity.

Observation:

  • A child presented with hepatic function deterioration 3 days post-depressed compound skull fracture and brain contusion.
  • Abdominal enhanced CT scan showed a wedge-shaped liver lesion and free intraperitoneal fluid.
  • Initial assessment suggested a traumatic liver injury.

Findings:

  • The liver lesion was ultimately attributed to acetaminophen toxicity, not direct trauma.
  • Ischemic hepatitis, potentially linked to the trauma, increased susceptibility to toxicity even at therapeutic acetaminophen doses.
  • Delayed CT imaging necessitated consideration of alternative diagnoses beyond trauma.

Implications:

  • Highlights the risk of acetaminophen toxicity in pediatric trauma patients with compromised liver perfusion.
  • Emphasizes the importance of considering non-traumatic causes of liver injury in post-trauma settings.
  • Suggests vigilance for acetaminophen-induced liver necrosis in cases of hepatic dysfunction following head injury.
