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.

Observational Study
Diagnostic and Prognostic Impact of pc-ASPECTS Applied to Perfusion CT in the Basilar Artery International Cooperation Study.
The posterior circulation Acute Stroke Prognosis Early CT Score (pc-APECTS) applied to CT angiography source images (CTA-SI) predicts the functional outcome of patients in the Basilar Artery International Cooperation Study (BASICS). We assessed the diagnostic and prognostic impact of pc-ASPECTS applied to perfusion CT (CTP) in the BASICS registry population. ⋯ CTP was performed in a minority of the BASICS registry population. Perfusion disturbances in the posterior circulation were most pronounced on MTT parameter maps. CBV pc-ASPECTS < 8 may indicate patients with high case fatality.

Patients with triple-negative breast cancer (TNBC) are at increased risk of brain metastases (BMs). In this retrospective single-institutional study, we assessed the radiographic features from a cohort of breast cancer (BC) patients with confirmed BM. ⋯ Patients with BMs from TNBC have distinct MRI features helping the assessment of newly developed BM. A large confirmatory study with correlated histology in this unique patient population will be required.

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.

To develop a qualitative brain magnetic resonance imaging (MRI) scoring system for comatose cardiac arrest patients that can be used in clinical practice. ⋯ A qualitative MRI scoring system helps assess hypoxic-ischemic brain injury severity following cardiac arrest and may provide useful prognostic information in comatose cardiac arrest patients.
