Background:
In pediatric patients presenting with neurological deficit in emergency department, special attention should be given to identify the conditions that can mimic a stroke to avoiding unnecessary interventions. There are various pathologies in pediatric populations that can mimic stroke both clinically and radiologically. Radiologists, by identifying specific imaging patterns of classical stroke and also patterns of those stroke mimics, shall aid clinician in deciding treatment options in a timely manner.

Objectives:
In this educational poster we aims at,
1) Discussing typical imaging patterns of ischemic stroke.
2) Discussing common pathologies in pediatric age group which can mimic ischimic stroke and pose challenge to the clinicians as well as radiologists.
3) Describing various imaging findings of those stroke mimics that help to differentiate from ischemic stroke.

We discuss the imaging patterns of following pediatric stroke mimics:
- Infective pathologies, including HSV encephalitis
- Demyelinating lesions.
- Vasculitis
- Migraine.
- Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS).
- Hypoxic ischemic encephalopathy.
- Moya Moya disease.
- Posterior reversible encephalopathy syndrome.
- Drug related pathologies.
- Miscellaneous conditions.

Conclusion:
Differentiation of commonly seen stroke mimics from ischemic stroke in a timely manner helps clinician for proper management and unnecessary interventions. Read More

Asthma is a common childhood disorder characterized by chronic reversible hyperresponsiveness in the small airways, resulting in obstructive physiology. Asthma is diagnosed either clinically or with pulmonary function tests. Imaging is often unnecessary unless there is concern for superimposed pneumonia or a complication related to an acute asthma exacerbation. However, pediatricians must maintain a high degree of suspicion for non-asthma pathologies that present similarly to asthma and may require imaging to ensure an accurate diagnosis. This pediatric case series describes these pathologies and provides case examples from our institution of children that were initially misdiagnosed as having asthma until the proper imaging study was performed.

Ultrasonography (US) is an essential tool in pediatric imaging, particularly in the emergency setting. Although US is often the favored initial modality for abdominal imaging in children, it is a highly operator-dependent modality prone to misinterpretation which can lead to false positive or negative exams, or even a different, incorrect diagnosis. Conditions discussed in this series include ileocolic intussusception, hypertrophic pyloric stenosis, appendicitis, and foreign bodies. We will review diagnostic criteria, highlight crucial findings, as well as illustrate commonly-encountered difficulties and mimics. Read More
