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.

Upper gastrointestinal studies are used for the diagnosis of intestinal malrotation, and the configuration of the duodenum and position of the DJ flexure are used for diagnosis. There are various challenges associated with diagnosing malrotation on the AP view, and obtaining a lateral view is recommended for diagnosis. To be useful, the lateral view must be of adequate quality. In addition, radiologists must be aware of the normal appearance and configuration of duodenal variants such as duodenum redundum, on the lateral view, as misdiagnosis of these may lead to unnecessary surgery. We aim to determine the proportion of lateral views considered of adequate quality for diagnosis, as well as the prevalence of a not previously described sign, the 'descending stair' and its correspondence to a diagnosis of duodenum redundum.
