Searching for Salvageable Brain: The Detection of Ischemic Penumbra Using Various Imaging Modalities?
Various imaging modalities are used to identify the ischemic penumbra in patients with acute ischemic stroke. Although single-photon emission computed tomography (CT), perfusion-weighted magnetic resonance imaging (MRI), and perfusion CT are used to evaluate residual cerebral blood flow in the ischemic area, validation of the perfusion threshold for the penumbra has not been established. The ischemic core corresponds generally to areas with early ischemic changes, such as parenchymal hypoattenuation on CT, restricted apparent diffusion coefficient on diffusion-weighted MRI, or very low cerebral blood volume on perfusion C...

Acute Foot Drop Syndrome Mimicking Peroneal Nerve Injury: An Atypical Presentation of Ischemic Stroke
We presented a 43-year-old man admitted to our hospital with acute weakness in the dorsiflexion of his right foot that appeared 3 days before admission. Brain magnetic resonance imaging diffusion-weighted sequence revealed a small area of restricted diffusion in the left frontal cortex. Three months later, his motor deficit had completely improved (modified Rankin scale score = 0). To our knowledge, this is the second report of sudden isolated foot drop caused by a cortical infarction.

Epileptic Seizure as a Precipitating Factor of Vascular Progressive Supranuclear Palsy: A Case Report
Conclusions: vPSP is a condition that should be considered when a patient presents with a gradually progressive clinical picture suggestive of idiopathic PSP associated with neuroimaging evidence of cerebrovascular disease. The occurrence of epileptic seizures has not been reported before in vPSP but they might trigger the onset or precipitate the course of the PSP-like disorders.

Meningeal Disease Masquerading as Transient Ischemic Attack
Conclusions: Our study confirmed that serious meningeal disease could present as TIA, but this disease was relatively uncommon among patients treated in a TIA clinic. The findings highlight the diagnostic value of MRI in patients with suspected TIA.

Diagnostic Accuracy and Risk Factors of the Different Lacunar Syndromes
Conclusions: The clinical diagnosis of patients with lacunar syndromes is inaccurate, especially among patients with sensorimotor syndrome. DWI is mandatory for obtaining an accurate diagnosis of the infarct.

Bilateral Anterior Choroidal Artery Infarction Presenting with Progressive Somnolence
A 55-year-old woman was admitted with a 3 days history of increasing lethargy with bradyphrenia and apathy. She progressively developed severe somnolence with marked abulia, right hemiparesis, right hemianopsia, and pseudobulbar palsy. Brain magnetic resonance imaging showed the rare image of bilateral acute anterior choroidal artery infarction. Pseudobulbar mutism and in rare cases abulia have been described in acute anterior choroidal artery infarction contralateral to an older lesion in mirror position. Although neurologic deterioration is not infrequent in anterior choroidal artery territory infarcts, the absence of f...

Prevalence and Clinicoradiological Analyses of Patients with Alzheimer Disease Coexisting Multiple Microbleeds
Conclusions: The present study indicated that the prevalence of multiple MBs was 17% in Japanese AD patients. The clinicoradiological profile suggested severe degree of CAA in patients with multiple L MBs (9%) and hypertension and aged changes in patients with multiple D/I MBs (8%). T2*-weighted imaging is a useful tool for evaluating degree of CAA and hypertensive vascular changes. We should pay more attention to management and care in AD patients with multiple MBs.

Relation between Cardiovascular Disease Risk Markers and Brain Infarcts Detected by Magnetic Resonance Imaging in an Elderly Population
Established cardiovascular risk markers, such as hypertension, are associated with increased risk of brain infarcts. The newer markers N-terminal pro-brain natriuretic peptide, troponin I, C-reactive protein, and cystatin C may affect the risk of cardiovascular events and potentially, thereby, also stroke. We investigated the association between established and new risk markers for cardiovascular disease and brain infarcts detected by magnetic resonance imaging (MRI) at age 75.

CADASIL with a Novel Mutation (Cys478Tyr)
Recently, an increasing number of NOTCH3 mutations have been described to cause cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Here, we report 2 CADASIL patients from a Japanese family, who were found to possess a novel NOTCH3 mutation. The proband only had chronic headache, and her mother had previously suffered a minor stroke. Although the patients' clinical symptoms were mild, their distinctive magnetic resonance imaging (MRI) features suggested CADASIL.

Utility of High-b-Value Diffusion-Weighted Magnetic Resonance Imaging in Evaluating Reversible Medial Longitudinal Fasciculus Syndrome Caused by Acute Brainstem Ischemia
Medial longitudinal fasciculus (MLF) syndrome refers to a gaze disorder characterized by impaired adduction on the ipsilateral side to the injured MLF, with dissociated nystagmus of the contralateral abducting eye. The most common cause of the MLF syndrome is ischemic stroke. However, acute ischemic change in the MLF may be undetectable even on diffusion-weighted magnetic resonance imaging (DW-MRI) partly because of its small size and specific brainstem location.

The 10-Second Stroke: A Case Report
Acute infarction is detected in a third of patients undergoing diffusion-weighted magnetic resonance imaging (DW-MRI) with clinically suspected transient ischemic attack. The longer symptoms are present, the more likely an infarct will be identified on DW-MRI. Events as short as 10 minutes have been reported in association with a DW-MRI lesion.

Stroke-Like Episodes Heralding a Reversible Encephalopathy: Microbleeds as the Key to the Diagnosis of Cerebral Amyloid Angiopathy–Related Inflammation—A Case Report and Literature Review
Cerebral amyloid angiopathy (CAA) is a common, often asymptomatic disease. Lobar intracerebral hemorrhage is the most frequent manifestation of CAA. Nevertheless, presentation of CAA with subacute cognitive decline, seizures, or headache with concomitant hyperintensities on T2-weighted magnetic resonance imaging (MRI) sequences and neuropathologic evidence of inflammation has been described. This disorder is known as CAA-related inflammation (CAA-ri).

Bilateral Medial Medullary Infarction with Nondominant Vertebral Artery Occlusion
Bilateral medial medullary infarction (MMI) is a rare stroke subtype. Here, we report a case with bilateral MMI caused by nondominant vertebral artery occlusion confirmed by brain digital subtraction angiography and magnetic resonance imaging basi-parallel-anatomical-scanning. We highlight that anterior spinal arteries could originate from a unilateral vertebral artery (VA). Radiologists and neurologists should pay attention to the nondominant VA as bilateral MMI may be induced by occlusion of nondominant VA that supplies the bilateral anteromedial territories of the medulla.

Limited versus Whole-Brain Perfusion for the Indication of Thrombolysis in the Extended Time Window of Acute Cerebral Ischemia
Perfusion computed tomography (PCT) has emerged as alternative to magnetic resonance imaging (MRI) for assessment of patients clinically qualifying for off-label thrombolysis within 4.5 to 9 hours after onset of ischemic stroke. However, disadvantage of PCT is its often limited anatomic coverage with only 2 or 3 slices when using a 4- to 64-section scanner. Our purpose was therefore to evaluate the value of 2- and 3-slice perfusion compared to whole-brain perfusion.
