Insights
A rare genetic liver condition, progressive familial intrahepatic cholestasis type 2 (PFIC2), can cause severe vitamin K deficiency bleeding (VKDB) in infants. This case highlights the need for comprehensive diagnosis beyond abusive head trauma for intracranial hemorrhages.
Area of Science:
- Pediatrics
- Genetics
- Hematology
Background:
- Abusive head trauma (AHT) is a critical medical emergency requiring prompt identification to prevent further harm.
- Intracranial hemorrhage in infants necessitates a thorough diagnostic evaluation to rule out various underlying causes.
Observation:
- A 4-month-old infant presented with a severe subdural hematoma.
- Initial suspicion of AHT was raised.
- Testing revealed vitamin K deficiency bleeding (VKDB) despite prophylaxis.
- The infant was diagnosed with progressive familial intrahepatic cholestasis type 2 (PFIC2).
Findings:
- PFIC2, a rare genetic liver disorder, can lead to severe VKDB.
- This is the first reported case of PFIC2 causing intracranial hemorrhage due to VKDB.
Implications:
- Comprehensive workup is essential for intracranial bleeding in infants.
- Consider rare genetic conditions beyond AHT and standard VKDB.
- This case broadens the differential diagnosis for infantile intracranial hemorrhage.
Introduction:
Abusive head trauma is a serious, often fatal condition; early identification is important to prevent repeat episodes and/or injuries to siblings. This case emphasizes the importance of a thorough workup in cases of suspected abusive head trauma.
Case Presentation:
A 4-month-old infant was found to have a severe subdural hematoma requiring surgical evacuation. Initially, abusive head trauma was considered as a diagnosis. Testing revealed vitamin K deficiency bleeding (VKDB) despite prophylactic vitamin K administration at birth. The infant eventually was diagnosed with progressive familial Iintrahepatic cholestasis type 2 (PFIC2).
Discussion:
Although VKDB is a known cause of infantile intracranial hemorrhage, PFIC has not been previously reported to cause severe VKDB resulting in an intracranial hemorrhage.
Conclusion:
Our case illustrates the importance of a comprehensive systematic approach to investigate causes other than abusive head injury when intracranial bleeding is a significant finding.
