Abstract:
Objective: The objective of this study is to identify the
characteristic neuroimaging (namely brain CT) as well as
physical findings found in young children with nonaccidental traumatic brain injury (TBI) and to compare them with accident cases of the similar age group, in order to study the specific features of the former group more precisely. Materials and methods: A cross sectional study was done involving 92 children aged 3 years old and below who were admitted to the Kuala Lumpur Hospital with
diagnosis of moderate to severe traumatic brain injury from
period of June 2007 to September 2009. These children were
categorized into non-accidental and accidental TBI and their physical examination data, brain computed tomography and skeletal surveys were done within one week from the date of admission were compared. Results: There was a male
predominance in both non-accidental and accidental TBI
groups with male-to-female ratio of 2:1 and 3:1 respectively.
The majority of the non-accidental TBI cases presented with
no definite history of trauma (52.2%) while most of the
accidental TBI cases were caused by motor vehicle accidents
(69.9%). Subdural haematomas appeared to be significantly
the most common brain haematomas among the nonaccidental
TBI as compared to the accidental group while
extradural haematomas were only present in the accidental
TBI group. Cerebral edema was also significantly more
common in the non-accidental group. Signs of pre-existing
brain injury, including cerebral atrophy and subdural
hygroma/effusion were present in 23.9% and 19.6%
respectively among children with non-accidental TBI and in
none of the children with accidental TBI. None of the
children in the non-accidental group diagnosed to have
shear injury while 6 (13.0%) of the children in the accidental group was diagnosed with diffuse axonal injury. In our series, retinal haemorrhage was significantly more common in the non-accidental TBI group (93.5%) as opposed to only 4(8.7%) children noted to have retinal haemorrhage in the accidental group. Seizures also occurred significantly more often in children with non-accidental TBI. Depressed skull fractures were only found in the accidental TBI group (19.6%), while other types of skull fractures occur more or less similar in both groups. Bodily fractures were also more predominant among the accidental group of TBI. Bodily lacerations/abrasions were only found in the accidental group while findings of bodily bruises were quite equal in both groups.
