Imaging of Suspected Stroke in Children, From the AJR Special Series on Emergency Radiology

Area of Science:

• Neurology
• Pediatric Medicine
• Medical Imaging

Background:

• Pediatric stroke, though uncommon, leads to significant short- and long-term adverse outcomes.
• Diagnostic delays in pediatric stroke are common due to overlapping symptoms with conditions like migraines and seizures.
• Accurate diagnosis relies on integrating clinical evaluation with advanced neuroimaging techniques.

Purpose of the Study:

• To review current neuroimaging protocols for diagnosing pediatric stroke in emergency settings.
• To compare the advantages and disadvantages of various neuroimaging modalities.
• To discuss predisposing conditions, stroke mimics, and age-specific diagnostic approaches.

Main Methods:

• Comprehensive review of neuroimaging workup for pediatric stroke.
• Analysis of different imaging modalities (e.g., MRI, CT) and their applications.
• Discussion of differential diagnoses, including stroke mimics.

Main Results:

• Neuroimaging is essential for confirming pediatric stroke and distinguishing it from mimics.
• Specific imaging techniques offer unique benefits and limitations in the pediatric population.
• Understanding predisposing factors and mimics aids in timely and accurate diagnosis.

Conclusions:

• Effective diagnosis of pediatric stroke requires a tailored neuroimaging strategy.
• Differentiating stroke from mimics is critical for appropriate management and improved outcomes.
• The approach to pediatric stroke diagnosis differs from that in adults.
