The clinical significance of vertebral artery hypoplasia (VAH) and the possible pathomechanism of ischemic stroke in patients with VAH are still not completely clear. ⋯ In patients with VAH, the combination of several pathomechanisms of ischemic stroke and the contribution of several risk factors can cause the clinical manifestation of PCS.

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.

Vascular imaging before intravenous thrombolysis: consequences of in-hospital delay in applying two diagnostic procedures.
Vascular imaging is increasingly used for diagnosis of arterial occlusions in acute ischemic stroke (AIS) patients. Our aim was to determine whether computed tomography angiography (CTA) and Doppler/duplex ultrasound (DUS) before intravenous thrombolysis (IVT) is associated with a delay in time-to-treatment. ⋯ Performing CTA before IVT seems to increase door-to-needle time. Vascular imaging based on DUS should be considered only if this does not lead to in-hospital delay.

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.

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.
