Abstract:
The deceased was a 6-month-old male infant who was transferred to the hospital due to jaundice and vomiting. During admission, subdural hemorrhage and retinal hemorrhage were observed; additionally, a rib fracture was identified on the previous radiography images, which had eventually healed by the time of the follow-up study. This case was reported to the police, alleging child abuse, which led to a medicolegal dispute between the hospital and the deceased's parents. In addition, bleeding tendency and coagulopathy related to vitamin K deficiency were also found. The past history revealed that the deceased had diarrhea, jaundice, and experienced several episodes of acholic stools, and low levels of vitamin D at birth. On postmortem examination, the brain already revealed liquefactive necrosis, but subdural hemorrhage was still observed. The optic nerves of both eyes revealed hemorrhage with focal retinal hemorrhage.No definite fracture was identified; however, osteopenia was observed in the long bones. The liver showed septal fibrosis and cholestasis which is nearly biliary cirrhosis, and mild dilation of the intrahepatic and extrahepatic bile ducts, suggesting a choledochal cyst. This case illustrates that subdural hemorrhage related to vitamin K deficiency could occur in an infant with a choledochal cyst.When subdural hemorrhage is encountered in a child with what is considered an intentional head injury, the possibility of spontaneous hemorrhage should be excluded.
