Cortical Microinfarcts Detected by 3-Tesla Magnetic Resonance Imaging: Differentiation Between Cerebral Amyloid Angiopathy and Embolism.

Background and Purpose- Cortical microinfarcts (CMIs) are small ischemic lesions found in cerebral amyloid angiopathy (CAA) and embolic stroke. This study aimed to differentiate CMIs caused by CAA from those caused by microembolisms, using 3-Tesla magnetic resonance imaging. Methods- We retrospectively investigated 70 patients with at least 1 cortical infarct <10 mm on 3-dimensional double inversion recovery imaging.

MEFV gene mutations in neuro-Behçet's disease and neuro-Sweet disease.

Mediterranean fever (MEFV) gene mutations are associated with familial Mediterranean fever (FMF). Recent studies have suggested that MEFV gene mutations may act as disease modifiers in neuro-Behçet's (NBD) disease and neuro-Sweet disease (NSD). We investigated MEFV genes and clinical features in 17 patients with NBD or NSD.

Microbleeds after Carotid Artery Stenting: Small Embolism May Induce Cerebral Microbleeds.

Background: Since the advent of magnetic resonance imaging technology, cerebral microbleeds can be diagnosed in vivo. However, the underlying mechanism of cerebral microbleed formation is not fully understood.

Objectives: This study aimed to identify the factors associated with cerebral microbleeds after carotid artery stenting (CAS).

Small Cortical Infarcts Transformed to Lobar Cerebral Microbleeds: A Case Series.

Cerebral microbleeds (MBs) have been often observed due to the development of imaging devices, and are classified to deep and lobar MBs. Lobar MBs are strongly associated with cerebral amyloid angiopathy. Here, we report 3 cases of lobar MBs that developed after small cortical ischemic stroke.
