PURPOSE OF REVIEW: Cerebral microbleeds (CMBs) are a radiological marker of cerebral small vessel disease corresponding to small haemosiderin foci identified by blood-sensitive MRI. CMBs are common in older community populations, and in individuals with ischaemic stroke or transient ischaemic attack (TIA), and intracerebral haemorrhage (ICH). We summarize how CMBs might contribute to assessing the future risk of ischaemic stroke and ICH to inform antithrombotic (antiplatelet or anticoagulant) decisions...

INTRODUCTION: Brain perfusion single photon computed tomography (SPECT) is a functional imaging modality and has been widely utilized in evaluation of various kinds of neurological disorders. Easy z-score imaging system (eZIS) is a computer-assisted statistical analysis, based on the comparison with age-classified ethyl cysteinate dimer (ECD) normal database, which provides objectively interpretation of Tc-99m ECD brain perfusion SPECT.Here we presented a 64-year-old male with dizziness, spin sensation, nausea, and vomiting in the emergency room, and brain computed tomography scan showed only small hypodensity lesion in cerebellum...

We report a case of interhemispheric and bifrontal cortical superficial siderosis in association with two intracranial aneurysms. The patient had no clinical history suggestive of aneurysm rupture, no feature of amyloid angiopathy or other apparent etiology for cortical siderosis. We performed high resolution brain MRI with dark blood T1 sequences before and after IV contrast injection. An anterior communicating aneurysm showed partial wall enhancement on the posterior wall whereas a left posterior communicating aneurysm did not...

BACKGROUND AND PURPOSE: Early markers for cerebral amyloid angiopathy are largely unknown. We aimed to identify which magnetic resonance imaging (MRI) (performed at 7 and 3T) and cognitive markers are an early sign in (pre) symptomatic subjects with hereditary cerebral hemorrhage with amyloidosis-Dutch type. METHODS: Twenty-seven DNA-proven Dutch-type mutation carriers (15 symptomatic and 12 presymptomatic) (mean age of 45.9 years) and 33 controls (mean age of 45...

Herein, we describe a case of 69 year old man who presented with gradual bilateral hearing impairment and unsteadiness. Examination showed bilateral sensorineural deafness and cerebellar ataxia. Neuroimaging revealed a rim of hypointensity surrounding the brain stem, superficial cerebellar fissures and extending into the cervical spinal cord consistent with the diagnosis of superficial siderosis (SS). Investigations failed to identify any reversible cause for the condition.

BACKGROUND AND PURPOSE: Transient focal neurological episodes occur in cerebral amyloid angiopathy (CAA) and can mimic transient ischemic attack (TIA). Risk factors and outcomes of minor ischemic stroke or TIA might differ in patients with and without cerebral microbleeds (CMBs), including CAA-consistent lobar CMB. METHODS: Baseline magnetic resonance imaging (MRI) was analyzed for CMBs and cortical superficial siderosis in 416 patients in the prospective computed tomography and MRI in the CATCH study (Triage of TIA and Minor Cerebrovascular Events to Identify High Risk Patients)...

Superficial siderosis of the central nervous system(SSCNS) is a rare disease characterized by hemosiderin deposition on the surface of the central nervous system. We report a case of SSCNS originating from the thoracic spine, presenting with neurological deficits including, sensorineuronal hearing loss, ataxia, and corticospinal and dorsal column tract signs. The patient underwent dural repair with an artificial dural patch. Clinical findings were elicited by neurological examination, imaging studies, and intraoperative findings, and these were addressed through literature review...

BACKGROUND: There is no doubt that cerebral amyloid angiopathy (CAA) is a key risk factor for recurrent lobar ICH, however, the exact mechanism and interaction with MRI markers of disease severity are less well known. Centrum semiovale-perivascular spaces (CSO-PVS) have been suggested as adjunctive diagnostic criteria in order to enhance diagnostic power. The purposes of this study were to investigate the prevalence of CSO-PVS and its association with other imaging signatures {lobar microbleeds (CMB), cortical superficial siderosis (CSS), white matter hyperintensity (WMH)} in lobar ICH patients as well as recurrent lobar ICH risk, especially in patients taking antithrombotic agents...
