<b>Background:</b> 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. <b>Objectives:</b> 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. <u><b>We discuss the imaging patterns of following pediatric stroke mimics:</b></u> - 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. <b>Conclusion:</b> Differentiation of commonly seen stroke mimics from ischemic stroke in a timely manner helps clinician for proper management and unnecessary interventions.

Mitochondrial diseases are a heterogeneous group of disorders caused by defects in intracellular energy production. Due to this heterogeneity, it is not surprising that multiple systematic approaches to diagnosis exist; all of which use a combination of clinical, biochemical and structural criteria. Several distinct syndromes have been recognized with variable clinical and imaging phenotypes, including Leigh's syndrome, Kearns-Sayre syndrome (KSS), mitochondrial encephalopathy with lactic acidosis and strokelike episodes (MELAS). In this exhibit, we discuss imaging morphology of various mitochondrial disease with emphasis on imaging protocol and diagnostic approach. Read More

The inner ear anomalies are a complex group of disorders, the radiologic findings of which may be difficult to interpret. This exhibit details the basic embryology of inner ear with stress on correlation of timing of insult or arrest of development to patho-morphology, the classification schema of inner ear anomalies and various salient features aiding in accurate diagnosis.
