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.

By pareidolically recognizing specific patterns indicative of particular diseases, neuroimagers reinforce their mnemonic strategies and improve their neuroimaging diagnostic skills. Joubert Syndrome (JS) is an autosomal recessive disorder characterized clinically by mental retardation, episodes of abnormal deep and rapid breathing, abnormal eye movements, and ataxia. Many neuroimaging signs characteristic of JS have been reported. ⋯ Neuroimaging diagnosis of JS, which already involves the pareidolical recognition of specific patterns indicative of the disease, can be improved by recognition of the shepherd's crook sign on MRI, CT, and cranial ultrasound.

Case Reports
Reversible cerebral periventricular white matter changes with corpus callosum involvement in acute toluene-poisoning.
Substance poisoning, such as toluene intoxication, has seldom been reported in the relevant literature. The documented cerebral neuroimaging has mostly described reversible symmetrical white matter changes in both the cerebral and cerebellar hemispheres. ⋯ We discussed the underlying neuropathological pathways in this article. Hopefully, these cases will provide first-line clinicians with some valuable information with regard to toluene intoxication and clinical neuroimaging presentations.

Randomized Controlled Trial Comparative Study
Relationship between Two Types of Coil Packing Densities Relative to Aneurysm Size.
Coil packing density (PD) can be calculated via a formula (PDF ) or software (PDS ). Two types of PD can be different from each other for same aneurysm. This study aimed to evaluate the interobserver agreement and relationships between the 2 types of PD relative to aneurysm size. ⋯ Interobserver agreement for PDF and PDS was excellent. However, PDF was overestimated in smaller aneurysms and converged to PDS as aneurysm size increased.
