Sickle cell disease is a common inherited disorder due to a structural abnormality in hemoglobin affecting the shape of the red blood cells. There are a variety of manifestations of this disease affecting a multitude of different organ systems. Some of the complications with the highest morbidity are those involving the central nervous system, and thus, the radiologist plays a pivotal role in the clinical management of these patients. It is important for the radiologist to understand the disease process, the radiologic manifestations, and the screening modalities available. Read More

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.

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.

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

Review the causes of cerebral hemorrhage in the pediatric patient based on clinical cases.

Stroke is a major cause of morbidity and mortality in children worldwide. The reported annual incidence ranges from 2.3 to 13 per 100,000 children per year in developed countries. In contrast to the adult, in children, diagnosis is not as straightforward, because when children present with acute neurological deficits, stroke is often not the first diagnosis considered by the medical providers.

Neuroimaging is essential for diagnosis and differentiation of stroke from stroke mimics that can present similarly.

Stroke in children can be ischemic or hemorrhagic, referring to the term hemorrhagic stroke as a intracerebral hemorrhage that is nontraumatic and whose most common etiology is secondary to a vascular malformation (Arteriovenous Malformation (AVM), Dural/Pial Arteriovenous Fistula (Dural AVF/Pial AVF), Cavernous Malformation, Vein of Galen Aneurysmal Malformation (VGAM), Developmental Venous Anomaly (DVA), Capillary telangiectasia, Sinus Pericranii, Aneurysms).

The most commonly used classification of vascular malformation is based on angioarchitectural and histomorphological characteristics. To differentiate these classic types, in a first step, shunting lesions have to be discerned from nonshunting lesions, as well as other features of the vascular contribution that will be evaluated by image.

We cannot forget the hemorrhage associated with coagulopathy, haematological disorders, brain tumors and cerebral sinovenous thrombosis (CSVT) which in the latter case can be found as venous infarction or hemorrhage; and other less common causes of hemorraghe in pediatrics as the intracranial aneurysms, in 15% of all pediatric aneurysms are secondary to an infection (micotic aneurysm).

An acute stroke MRI protocol is used when a paediatric patient presents to the emergency department with stroke like symptoms. Rapid imaging is needed in order to ascertain the presence of stroke, exclude stroke mimics, the extent of the stroke, and exclude any complications, such as haemorrhage. An acute stroke protocol which consist only of a diffusion weighted sequence enables quick diagnosis and does not significantly delay treatment of the patient. Read More

Advanced neuroimaging techniques are increasingly being used in the assessment of pediatric stroke and pediatric neurovascular disease. There is mounting evidence that noncontrast brain perfusion, contrast brain perfusion, and vessel wall imaging provide added clinical value in pediatric cerebrovascular disease. This presentation will outline the current literature and demonstrate the utility of these techniques through a pictorial case review of applications in pediatric stroke and related neurovascular pathologies. Technical guidelines and recommendations for each imaging modality will also be discussed. We aim to demonstrate a role for these techniques in pediatric diagnostic algorithms and neuroimaging protocols. Read More

Congenital heart disease (CHD) is the most common type of birth defect; affecting ~1% of the births per year in the U.S. Advancements in medical and surgical treatment have markedly improved survival and even infants with complex CHD survive into adulthood. However, extracardiac complications in the newborn period can cause increased morbidity and mortality. These complications can relate to alteration in flow dynamics, treatment changes, and/or sequelae of associated syndromes (Trisomy 21, 22q deletion syndrome, Heterotaxy, PHACES). The purpose of this exhibit is to highlight extracardiac complications of CHD and to review their imaging findings. Imaging findings to be reviewed will include catheter thromboses, necrotizing enterocolitis, arterial ischemic strokes, infections, malrotation, pulmonary complications related to prematurity, prolonged intubations, and associated syndromes, and complications of extracorporeal membrane oxygenation. The goal of this exhibit is to familiarize radiologists with the multiplicity of extracardiac complications in infants with CHD and to review the common imaging findings. Read More
