Perinatal Hypoxic Ischemic Injury (HII) has a higher prevalence in the developing world. One of the primary concepts for suggesting that an imaging pattern reflects a global insult to the brain is when the injury is noted to be bilateral and symmetric in distribution. In the context of HII in term neonates, this is either bilateral symmetric (a) peripheral/watershed injury (WS) or (b) bilateral symmetric Basal-ganglia-thalamus (BGT) pattern, often with the peri-Rolandic and hippocampal injury. Unilateral, asymmetric or unequal distribution of injury may therefore be misdiagnosed as perinatal arterial ischemic stroke. This has been previously reported in the typical distribution patterns, without a clear indication of the prevalence. We aimed to determine the prevalence of unilateral, asymmetric and unequal degree HII and to characterize the distribution on MRI in a large database of patients with Cerebral Palsy (CP) from South Africa.
