Neonatal Central Nervous System Infection
No full textAbstractIn this review article, neuroimaging features of common bacterial, viral, fungal, and parasitic infections of the pediatric central nervous system (CNS) are discussed. Imaging modalities used by pediatric neuroradiologists include cranial ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). After a brief discussion of the clinical presentation of each disease entity, imaging strategies and findings are reviewed. The role of advanced neuroimaging techniques is discussed wherever appropriate.</jats:p
Imaging in Nontraumatic Pediatric Head and Neck Emergencies
No full textAbstractPediatric patients often present to the emergency department with a wide variety of infectious, inflammatory, and neoplastic lesions of the head and neck. Evaluation of pediatric patients in the emergency setting is complicated by limited history and physical examination. Imaging plays an important role in arriving at an accurate diagnosis. The fascial spaces and compartments of the neck provide an approach to differential diagnosis, and knowledge of the typical clinical and imaging manifestations of common pediatric head and neck emergencies allows the radiologist to identify the condition and associated complications that may require emergent surgical management. Computed tomography (CT) is the first-line imaging modality in the emergency setting; however, magnetic resonance imaging (MRI) plays an important secondary role.</jats:p

Preoperative Localization of Parathyroid Adenomas Using 4-Dimensional Computed Tomography: A Pictorial Essay
No full textAbstractAccurate preoperative localization is the key to successful parathyroid surgery in the era of minimally invasive parathyroid surgery. This article presents and discusses the embryologic basis of parathyroid gland and ectopic location and different imaging modalities helpful in diagnosing and localizing parathyroid adenomas and/or hyperplasia. We also aim to review the current surgical concepts in treatment of parathyroid adenomas and/or hyperplasia, the utility of 4-dimensional computed tomography for accurate preoperative localization of hyperfunctioning parathyroid glands, imaging classification of adenomas and/or hyperplasia, and, finally, present some of the limitations of 4-dimensional computed tomography
Prevalence of SLEC-negative spontaneous intracranial hypotension in patients with spinal nerve root sleeve diverticula on MRI.
No full textPURPOSE: While there is thought to be an association between spinal nerve root diverticula (NRD) and spontaneous intracranial hypotension (SIH) without a spinal longitudinal epidural collection (SLEC), it remains unclear what the overall prevalence of SLEC-negative SIH is in patients with NRD on MRI.
METHODS: Spine MRI imaging reports from our single institution were electronically screened for instances of NRD over a 9-year period (2016-2023). From these cases, patients with brain MRIs consistent with SIH were also identified. Subsequently, the overall proportion of SLEC-negative SIH was determined as a function of total cases with NRD based on spinal level.
RESULTS: In total, 83,843 patients with spinal MRIs were screened which identified 4174 (4.97%) with NRD. From these, there were 1203 cervical, 622 thoracic, and 2979 lumbosacral spine MRIs. In total, 16 patients (0.38%; Standard Error [SE]: 0.48%-0.28%) had a brain MRI compatible with SLEC-negative SIH and met ICHD-3 criteria. Patients with cervical NRD had SIH in 2 cases (0.16%; SE: 0.27%-0.05%). SLEC-negative SIH was present in 11 patients with lumbosacral NRD (0.34%; SE: 0.44%-0.24%). In patients with diverticula in the thoracic spine, 14 (2.3%; SE: 2.8%-1.8%) had SLEC-negative SIH. SLEC-negative SIH was significantly more prevalent in patients with thoracic diverticula compared to those with cervical (
CONCLUSION: In patients with spinal NRD, concurrent SLEC-negative SIH is present in approximately 0.38% of patients, suggesting that in the vast majority of cases, they are an incidental finding. However, SIH is present in approximately 2.3% of patients with thoracic NRD and may be more specific for leak localization
