Single Subcortical Infarct: Pathomechanism Assessed by Thin-Section Computed Tomography Perfusion
The pathomechanism of a single subcortical infarct (SSI) may be better determined by assessing the perfusion status between parent artery and ischemic lesion. We aimed to compare the classifications into branch atheromatous disease (BAD) versus non-BAD based on diffusion-weighted imaging (DWI) or computed tomography perfusion (CTP), and to test whether a CTP-based classification improves the predicting power for progression in SSI (PSSI) compared to that by DWI.

Paradoxical Embolism in a Girl with Atrial Septal Defect After Paroxysmal Supraventricular Tachycardia Ablation
Paradoxical embolism is a kind of important pathogenesis of cardiocerebrovascular diseases. In our case, radiofrequency current catheter ablation was accomplished successfully in a 15-year-old girl who had been experiencing supraventricular tachycardia for 6 months. She presented with abrupt onset of left hemiplegia and loss of consciousness on the first postoperative day. An urgent cerebral computed tomography showed a hyperdense right middle cerebral artery. Transthoracic echocardiogram examination revealed an atrial septal defect (ASD), with the diameter measuring 39 mm.

Lobar Hemorrhage Induced by Acquired Factor XIII Deficiency in a Patient with Cerebral Amyloid Angiopathy
A 68-year-old man presented with intracranial hemorrhage in the right frontal lobe, which rapidly increased the day after admission. We performed hematoma removal with a biopsy of the cortex around the hematoma. The day after the operation, a subcutaneous hematoma over the craniotomy appeared, and the computed tomography showed a recurrent hemorrhage with an acute subdural hematoma. We were aware of a bleeding tendency, and a detailed hematologic examination by hematologists revealed autoimmune acquired factor XIII deficiency due to an antifactor XIII antibody.

Case of 78-Year-Old Male with Cerebral Gas Embolism Associated with Combined Pulmonary Fibrosis and Emphysema
Cerebral gas embolism (CGE) from the thoracic cavity is commonly associated with invasive procedures, and cases of spontaneous CGE are rare. A 78-year-old man presented with severe spontaneous CGE associated with combined pulmonary fibrosis and emphysema (CPFE). To the best of our knowledge, the comorbidity of CGE in a CPFE patient has not been documented until now. The patient became unconscious with left hemiparesis at approximately 2 a.m. Computed tomography scan revealed minute air densities scattered in the deep white matter of the right frontal lobe.

Herniation despite Decompressive Hemicraniectomy in Large Hemispherical Ischemic Strokes
Despite decompressive hemicraniectomy (DHC), progressive herniation resulting in death has been reported following middle cerebral artery (MCA) strokes. We aimed to determine the surgical parameters measured on brain computed tomography (CT) scan that are associated with progressive herniation despite DHC in large MCA strokes.

Agenesis of the Left Internal Carotid Artery Associated with Dolichoectatic Intracranial Arteries
A 28-year-old man without a significant medical history visited our hospital complaining of a headache. Computed tomography (CT) demonstrated thick, calcified vertebral artery (VA) and basilar artery (BA), despite the patient being young. Magnetic resonance angiography demonstrated the absence of the left internal carotid artery (ICA). The right ICA, the bilateral VA, and the BA were well developed and dolichoectatic. CT revealed the absence of the carotid canal on the left side. The condition was diagnosed as congenital agenesis of the left ICA with dolichoectatic changes in 3 other arteries.

Cerebral Infarcts by Nonbacterial Thrombotic Endocarditis Associated with Adenomyosis: A Case Report
We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular territory infarctions involving the bilateral cerebellum and the right precentral gyrus. Magnetic resonance angiography was normal. d-Dimer, carbohydrate antigen (CA) 19-9, and CA125 levels were elevated. Abdominal and pelvic computed tomography with iodine contrast enhancement revealed a huge adenomyosis with left ovarian cyst.

Yield of Computed Tomography (CT) Angiography in Patients with Acute Headache, Normal Neurological Examination, and Normal Non Contrast CT: A Meta-Analysis
Patients with acute severe headache, normal neurological examination, and a normal noncontrast head computed tomography (NCCT) may still have subarachnoid hemorrhage, cerebral venous thrombosis (CVT), cervical arterial dissection, or reversible cerebral vasoconstriction syndrome (RCVS). Computed tomography angiography (CTA) is used increasingly in the emergency department for evaluating this, but its added value remains controversial.

Hyperperfusion after Clipping of Aneurysm: A Rare Entity
Cerebral vasospasm is an uncontrollable and sometimes fatal complication occurring after subarachnoid hemorrhage. However, cerebral hyperperfusion syndrome is a rare complication after subarachnoid hemorrhage. Although plain computed tomography of cerebral hyperperfusion syndrome looks similar to cerebral infarction induced by cerebral vasospasm, they should be distinguished from each other because they require completely different treatments.

Lenalidomide-Induced Ischemic Cerebrovascular Disease in Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Gammopathy, and Skin Changes Syndrome
We describe the case of a 34-year-old woman with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. She developed transient ischemic attack after the introduction of lenalidomide plus dexamethasone (Rd) therapy despite no vascular risk factors. Magnetic resonance and computed tomography angiographies showed bilateral internal carotid artery stenosis. Rd therapy was suspended because of its thromboembolic risk. She had been neurologically stable during the suspension of Rd therapy.

The Basilar Artery on Computed Tomography Angiography Score for Acute Basilar Artery Occlusion Treated with Mechanical Thrombectomy
Recently, the Basilar Artery on Computed Tomography Angiography (BATMAN) score predicts clinical outcome of acute basilar artery occlusion (BAO), yet there is no extensive external validation. The purpose of this study was to validate the prognostic value of BATMAN scoring system for the prediction of clinical outcome in patients with acute BAO treated with endovascular mechanical thrombectomy by using cerebral digital subtraction angiography (DSA).

Multiple Thrombi in the Heart in Trousseau Syndrome Caused by Pancreatic Carcinoma
A 65-year-old woman presented to our emergency room because of sudden onset of right hemiparesis with severe fatigue. Neurological examination revealed right hemiparesis with right facial numbness and an extensor planter response on the right side.Magnetic resonance imaging with diffusion-weighted imaging revealed multiple highintensity areas in both cerebral hemispheres and the right cerebellum. A diagnosis of acute stage of multiple brain infarctions caused by emboli was made. An abdominal computed tomography showed a pancreatic tumor with multiple liver metastases.
