Small obliquely oriented cortical cerebellar infarctions are associated with cardioembolic stroke.

Background: A revised classification of cerebellar infarctions (CI) may uncover unrecognized associations with etiologic stroke subtypes. We hypothesized that obliquely oriented small cortical cerebellar infarction (SCCI) representing end zone infarctions on MRI would be associated with cardiac embolism.

Methods: We retrospectively analyzed consecutive stroke patients recruited between January-December 2016 in our center.

Subarachnoid extension of lobar hemorrhage on acute/subacute MRI is associated with cerebral amyloid angiopathy criteria.

Subarachnoid hemorrhage extension (SAHE) in the acute phase of cerebral amyloid angiopathy (CAA)-related lobar hemorrhage (LH) assessed by CT is very frequent. Recently, SAHE, together with finger-like projections on CT and ApoE4, has been used in a prediction model for histopathologically proven CAA showing excellent discrimination. Our aim was to analyze SAHE on MRI in the acute and subacute phase of LH in patients with and without associated hemorrhagic features supportive of CAA (i.

Anatomical relationship between carotid artery and styloid and hyoid bones in patients showing unintended head rotation on CTA.

Styloid process length and styloid/hyoid bone proximity to the internal carotid artery (ICA) have been implicated in certain carotid pathologies (e.g. carotid artery dissection).

Cerebral Amyloid Angiopathy and Cerebral Amyloid Angiopathy-Related Inflammation: Comparison of Hemorrhagic and DWI MRI Features.

Background: Cerebral amyloid angiopathy (CAA) can be associated with primary vasculitis of small/medium-sized leptomeningeal and cortical arteries, called CAA-related inflammation (CAA-ri).

Objective: To compare hemorrhagic and diffusion-weighted imaging (DWI) MRI features in CAA and CAA-ri.

Methods: We prospectively scored in a consecutive CAA and CAA-ri cohort: presence/number of chronic intracerebral hemorrhage (ICH), cerebral microbleeds (CMB), and cortical superficial siderosis (CSS) on initial T2*-weighted imaging, and DWI lesions on both initial and follow-up imaging.

Infratentorial Cerebral Microbleeds in Patients with Cerebral Amyloid Angiopathy.

Background: Cerebral microbleeds (CMBs) observed in hypertension-related arteriolosclerosis tend to occur in the supratentorial deep gray matter, whereas those in cerebral amyloid angiopathy (CAA) typically show a supratentorial lobar distribution. Recently, superficial spontaneous cerebellar intracerebral hemorrhage has been shown to be associated with strictly lobar CMBs. Few data exist on infratentorial CMBs in CAA.

Characterizing Deep White Matter Hyperintensities in Patients with Symptomatic Isolated Cortical Superficial Siderosis.

Background: In patient with cerebral amyloid angiopathy (CAA) presenting with lobar hemorrhage (LH), magnetic resonance imaging (MRI) white matter hyperintensities (WMH) tend to be predominant in posterior regions with the "multiple subcortical spots" WMH pattern as the most frequent topographical WMH pattern. Our aim was to analyze WMH severity and topographical distribution in patients with cortical superficial siderosis (CSS).

Methods: We retrospectively analyzed MRIs from consecutive symptomatic isolated (i.
