Pediatric spinal trauma is unique. The developing pediatric spinal column and spinal cord deal with direct impact and indirect acceleration/deceleration or shear forces very different compared to adult patients. In addition children are exposed to different kind of traumas. ⋯ Magnetic resonance imaging is more sensitive for disco-ligamentous and spinal cord injuries. Depending on the clinical presentation and timing of trauma the various imaging modalities will be employed. In the current review article, a summary of the epidemiology and distribution of posttraumatic lesions is discussed in the context of the normal anatomical variations due to progressing development of the child.

The aim of this study is to explore the possible changed cerebral white matter regions in patients with temporal lobe epilepsy (TLE) using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS). ⋯ TLE is associated with widespread abnormalities in cerebral white matter tracts and these changes may have important clinical consequences.

Cardiac Echoscan is the simplified transthoracic echocardiogram focused on the main source of emboli detection in the acute stroke diagnosis (Stroke Echoscan). We describe the clinical impact related to the Stroke Echoscan protocol in our Center. ⋯ The Echoscan protocol was an accurate quick test, which reduced the length of stay and increased the percentage of severe AA plaque diagnosis.

Case Reports
Neurofibromatosis type 1 associated with vertebrobasilar dolichoectasia and pontine ischemic stroke.
Neurofibromatosis type 1 (NF1) is a heterogeneous, common, neurocutaneous disorder presenting different complications during a life span, including cerebrovascular dysplasia. To our knowledge this is the first reported case of NF1 associated with vertebrobasilar dolichoectasia and pontine ischemic stroke. We describe a 57-year-old man with NF1 who presented an acute onset right-sided facial palsy and hemiplegia, dysarthria, and gait imbalance. ⋯ Brain Computed Tomography Angiography revealed the occurrence of vertebrobasilar dolichoectasia. Co-occurrence of VBD and NF1 might not be merely casual and it may significantly heighten the mortality rate in this multisystem disorder. We suggest a possible role of VBD in the genesis of our patient's clinical-radiological features and prompt the early detection of asymptomatic arteriopathy in individuals with NF1 in order to ameliorate patients' quality of life and life expectancy.

The high variability of CSF volumes partly explains the inconsistency of anesthetic effects, but may also be due to image analysis itself. In this study, criteria for threshold selection are anatomically defined. ⋯ The estimation of a close range of CSF volumes which probably contains the real CSF volume value can be standardized and calculated prior to certain intrathecal procedures.
