BACKGROUND: The association of a hemorrhagic tumor with secondary superficial siderosis (SS) is a relatively rare although well described phenomenon. CASE DESCRIPTION: We present the case report of a 35-year-old male with a history of drowsiness, hypoacusia, drop attacks, and multidirectional nystagmus during the last 2 months, who presented with acute obstructive hydrocephalus caused by a fourth ventricle mass displaying radiological signs of repeated intra and extratumoral hemorrhage with SS...

The risk of future symptomatic intracerebral haemorrhage (sICH) remains uncertain in patients with acute convexity subarachnoid haemorrhage (cSAH) associated with suspected cerebral amyloid angiopathy (CAA). We assessed the risk of future sICH in patients presenting to our comprehensive stroke service with acute non-traumatic cSAH due to suspected CAA, between 2011 and 2016. We conducted a systematic search and pooled analysis including our cohort and other published studies including similar cohorts. Our hospital cohort included 20 patients (mean age 69 years; 60% male); 12 (60%) had probable CAA, and 6 (30%) had possible CAA according to the modified Boston criteria; two did not meet CAA criteria because of age <55 years, but were judged likely to be due to CAA...

OBJECTIVE: Cerebral amyloid angiopathy (CAA) is a common age-related small vessel disease (SVD). Patients without intracerebral hemorrhage (ICH) typically present with transient focal neurologic episodes (TFNEs) or cognitive symptoms. We sought to determine if SVD lesion burden differed between patients with CAA first presenting with TFNEs vs cognitive symptoms. METHODS: A total of 647 patients presenting either to a stroke department (n = 205) or an outpatient memory clinic (n = 442) were screened for eligibility...

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...

Central nervous system infratentorial superficial siderosis (iSS) is increasingly detected by blood-sensitive magnetic resonance imaging (MRI) sequences. Despite this, there are no standardized diagnostic criteria, and the clinical-radiological spectrum, causes, and optimum investigation strategy are not established. We reviewed clinical and radiological details of patients with iSS assessed at a specialist neurological center during 2004-2016 using predefined standardized radiological criteria. All imaging findings were rated blinded to clinical details...

BACKGROUND: Sensorineural hearing impairment is a key symptom in patients with superficial siderosis of the central nervous system, a disease caused by chronic or intermittent haemorrhage into the subarachnoid space. We investigated the prevalence and risk factors of subjective hearing impairment after SAH. METHODS: We systematically interviewed all SAH patients admitted between June 2011 and December 2014, who were able to visit the SAH outpatient clinic six to eight weeks after hospital discharge...

OBJECTIVE: To investigate CSF biomarkers in presymptomatic and symptomatic mutation carriers with hereditary cerebral hemorrhage with amyloidosis-Dutch type (HCHWA-D), a model for sporadic cerebral amyloid angiopathy, and to determine the earliest deposited form of β-amyloid (Aβ). METHODS: HCHWA-D mutation carriers and controls were enrolled in the cross-sectional EDAN (Early Diagnosis of Amyloid Angiopathy Network) study. The HCHWA-D group was divided into symptomatic carriers with a previous intracerebral hemorrhage and presymptomatic carriers...

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...

Importance: Hematoma expansion is an important determinant of outcome in spontaneous intracerebral hemorrhage (ICH) due to small vessel disease (SVD), but the association between the severity of the underlying SVD and the extent of bleeding at the acute phase is unknown to date. Objective: To investigate the association between key magnetic resonance imaging (MRI) markers of SVD (as per the Standards for Reporting Vascular Changes on Neuroimaging [STRIVE] guidelines) and hematoma volume and expansion in patients with lobar or deep ICH...

BACKGROUND AND PURPOSE: Cerebral microbleeds (CMBs), cortical superficial siderosis, white matter lesions (WML), and cerebral atrophy may signify greater bleeding risk particularly in patients in whom anticoagulation is to be considered. We investigated their prevalence and associations with stroke type in patients with stroke and atrial fibrillation (AF). MATERIALS AND METHODS: Cross-sectional sample, Monash Medical Centre (Melbourne, Australia) between 2010 and 2013, with brain MRI...

OBJECTIVE: To identify predictors of early lobar intracerebral hemorrhage (ICH) recurrence, defined as a new ICH within 6 months of the index event, in patients with cerebral amyloid angiopathy (CAA). METHODS: Participants were consecutive survivors (age ≥55 years) of spontaneous symptomatic probable or possible CAA-related lobar ICH according to the Boston criteria, drawn from an ongoing single-center cohort study. Neuroimaging markers ascertained in CT or MRI included focal (≤3 sulci) or disseminated (>3 sulci) cortical superficial siderosis (cSS), acute convexity subarachnoid hemorrhage (cSAH), cerebral microbleeds, white matter hyperintensities burden and location, and baseline ICH volume...

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.
