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.

Acute Intracranial and Spinal Subdural Hematoma Associated with Vardenafil
A 28-year-old healthy man was admitted to our hospital because of right-sided headache, vomiting, and lower back pain after the administration of vardenafil. Computed tomography and magnetic resonance imaging of the brain showed a small, right-sided, subdural hematoma. A lumbar magnetic resonance imaging showed a longitudinally extended subdural hematoma. He had no history of trauma. We speculated that vardenafil might have had an association with the bleeding. Several reports have suggested a relationship between phosphodiesterase-5 inhibitors and intracerebral or subarachnoid hemorrhage.

Nonaneurysmal “Pseudo-Subarachnoid Hemorrhage” Computed Tomography Patterns: Challenges in an Acute Decision-Making Heuristics
Acute aneurysmal subarachnoid hemorrhage (SAH) is a medical and neurosurgical emergency from ruptured brain aneurysm. Aneurysmal SAH is identified on brain computed tomography (CT) as increased density of basal cisterns and subarachnoid spaces from acute blood products. Aneurysmal SAH-like pattern on CT appears as an optical illusion effect of hypodense brain parenchyma and/or hyperdense surrounding cerebral cisterns and blood vessels termed as “pseudo-subarachnoid hemorrhage” (pseudo-SAH).

Rectus Sheath Hematoma Following Intravenous Thrombolysis With Recombinant Tissue Plasminogen Activator for Cerebral Infarction: A Case Report
A 76-year-old Japanese man was admitted to our department because of aphasia and right hemiparesis. Brain magnetic resonance imaging showed cerebral infarction caused by occlusion of the left middle cerebral artery, and alteplase therapy was started. Thrombectomy was subsequently performed, resulting in recanalization. On day 4 after admission, he complained of epigastric pain when coughing. On day 8, contrast-enhanced computed tomography showed a left abdominal rectus sheath hematoma without extravasation.

Evaluation of a CTA-Triage Based Transient Ischemic Attack Service: A Retrospective Single Center Cohort Study
We designed a computed tomography angiography (CTA)-based algorithm for patients presenting to hospital with a transient ischemic attack (TIA) which identified high-risk patients, as well as inpatient versus semiurgent outpatient management following MRI, and we hypothesised that this would be effective.

Vernet's Syndrome Associated with Internal Jugular Vein Thrombosis
Our objective is to present a case of Vernet's syndrome (cranial nerve (CN) IX, X, and XI palsy) associated with cerebral venous thrombosis (CVT) in an internal jugular vein. The patient presented with acutely developed dysphagia. The weakness of the left sternocleidomastoid and trapezius muscles was observed. The initial magnetic resonance imaging and computed tomography (CT) with contrast enhancement showed contrast-filling defect in the left internal jugular vein inside the jugular foramen. The magnetic resonance venography with contrast enhancement revealed a partial filling defect in the left sigmoid sinus and total o...

A High Prevalence of Intracranial Stenosis in Patients with Coronary Artery Disease and the Diagnostic Value of Transcranial Duplex Sonography
Background: According to the data from the population-based Rotterdam study, intracranial carotid artery calcification detected by computed tomography is very common and contributed to 75% of all strokes. The aim of the present study was to estimate the prevalence of intracranial stenosis (IS) using noninvasive transcranial color-coded duplex sonography (TCCS) in neurologically asymptomatic patients with coronary artery disease (CAD). Methods: Three hundred and eighty-nine patients with angiographically-confirmed, severe CAD were included prospectively.

Progressive Cerebral Ischemia and Intracerebral Hemorrhage after Indirect Revascularization for a Patient with Cerebral Proliferative Angiopathy
We previously reported a patient with cerebral proliferative angiopathy (CPA) who showed cerebral ischemia in resting and acetazolamide-stressed N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography (123I-IMP-SPECT). At onset, the patient was treated conservatively. However, during the 2 years following initial onset, his hemiparesis and aphasia had gradually aggravated and his IQ scores were markedly decreased. MRI revealed progressive vascular proliferation and brain atrophy.

Anterior Choroidal Artery Infarction Evaluated with 123I-Imp Single-Photon Emission Computed Tomography and 7 Tesla Magnetic Resonance Imaging
Anterior choroidal artery (AchA) infarction remains a challenging diagnosis although it was first described almost 100 years prior. N-isopropyl-p-[123I]-iodoamphetamine single-photon emission computed tomography (123I-IMP SPECT) and 7 Tesla magnetic resonance angiography (7T-MRA) are not routinely performed in cases of AchA infarction. Therefore, the application of 123I-IMP SPECT and 7T-MRA for AchA infarction has not been reported previously. A 67-year-old man presented with disturbed consciousness, gaze preference to the left, aphasia, right homonymous hemianopia, and right hemiparesis.

Cortical Vein Opacification for Risk Stratification in Anterior Circulation Endovascular Thrombectomy
Introduction: There is continued interest in identifying factors that predict a favorable outcome after endovascular thrombectomy (EVT) for anterior circulation large vessel occlusion (ACLVO). We compared the predictive values of 2 different scoring systems for evaluating venous collateral circulation. Methods: A retrospective review of patients who underwent EVT for ACLVO at a single institution was performed. Those who underwent preprocedural computed tomography angiography (CTA) were selected.

T2*-Weighted MRI Detected Dilated Cerebral Veins in a Patient With Acute-Phase Cerebral Venous Sinus Thrombosis —A Case Report
We describe a 45-year-old man who presented with nausea, vomiting, and strong occipital headache on the right side. Although no abnormalities on neurological examination or computed tomography imaging were found on admission, peripheral blood cell counts showed polycythemia (hemoglobin 20.6 g/dL) and electrocardiography demonstrated atrial fibrillation. Therefore, anticoagulant treatment with heparin was started immediately. On the following day, the occipital headache continued. Brain T2*-weighted (T2*WI) magnetic resonance imaging (MRI) and, to a lesser extent, susceptibility-weighted imaging showed dilation of numerous ...

Blood Type O Predicts Hematoma Expansion in Patients With Intracerebral Hemorrhage
Background: Hematoma expansion after acute spontaneous intracerebral hemorrhage (ICH) is well established to result in poor prognosis. Recent studies have demonstrated that the ABO blood type system has potential implications on hemostatic properties. The purpose of this study was to explore the potential association of blood type O with hematoma expansion in patients with ICH and validate the usefulness in predicting early hematoma expansion. Methods: We retrospectively enrolled consecutive patients with ICH who underwent baseline computed tomographic (CT) scan within 6 hours after onset of symptoms.

Relationship Between Asymptomatic Intracranial Stenosis and Extracranial Arteriosclerotic Findings in Workplace Health Checkups: A Pilot Study
Background: Intracranial arteriosclerotic disease (ICAD) is common in Asians and has been presumed to be largely associated with metabolic syndrome (MetS), but the risks for asymptomatic ICAD detectable in examinations of the brain, among other tests, are not well known. The present study is aimed at identifying the risks for asymptomatic ICAD using data on risk factors obtained in health checkups, including data from magnetic resonance imaging (MRI), chest computed tomography (CT), and neck echography.
