Background and Purpose: Complex wide-neck intracranial aneurysms are challenging to treat. We report a multicenter experience using the LVIS Jr stent for "Y-stent"-assisted coiling embolization of wide-neck bifurcation aneurysms. Methods: Seven centers provided retrospective data on patients who underwent Y-stenting. Technical complications, immediate posttreatment angiographic results, clinical outcomes, and imaging follow-up were assessed. Results: Thirty patients/aneurysms were treated: 15 basilar tip, 8 middle cerebral artery, 4 anterior communicating artery, 1 pericallosal, and 2 posterior inferior cerebellar artery aneurysms...

Background: Too many patients, with or without significant cervical disease, unnecessarily undergo cervical epidural steroid injections (CESIs). These include interlaminar (ICESI) and transforaminal ESI (TF-CESI) injections that are not Food and Drug Administration (FDA) approved, have no documented long-term efficacy, and carry severe risks and complications. Methods: Here we reviewed recent reports of morbidity and mortality attributed to the various types of CESIS...

A 69-year-old man was admitted to the emergency department with headache and dizziness. He was submitted to brain computed tomography (CT) which showed a tumor in the right cerebellar hemisphere, findings which were subsequently confirmed with magnetic resonance imaging (MRI). He underwent a paramedian suboccipital craniotomy for removal of the mass. Histology confirmed the presence of a hemangiopericytoma. The patient was discharged 5 days postoperatively with improvement in his symptoms. Fifteen days later, he presented with gait difficulties...

Concomitant cerebral infarction developing soon after a parenchymal intracerebral hemorrhage is a rare occurrence. Usually, these remote site changes follow tumor decompression and are associated with hemorrhagic changes rather than infarcts. We report a case of a fatal malignant internal carotid territory infarct in a hospitalized patient being conservatively managed for a vermian hematoma and discuss the probable pathophysiology. Stroke physicians need to be aware that spontaneous intracerebral hematoma patients have a potential threat of developing large vessel occlusion with malignant cerebral infarcts, especially after surgical decompression...

BACKGROUND: Superficial temporal artery (STA) -to- superior cerebellar artery (SCA) bypass is associated with a relatively high risk of surgical complications, such as hematoma and/or edema caused by temporal lobe retraction. Therefore, the right side is typically used to avoid retraction of the left temporal lobe. In this report, we present a case of left STA-SCA bypass with anterior petrosectomy to avoid retraction of dominant side temporal lobe and describe the surgical technique in detail...

Background Acute ischemic stroke (AIS) more frequently develops in patients with intracranial vertebral artery dissection (VAD) than extracranial VAD, and is associated with possible poor clinical outcomes. The aim of this study is to compare high-resolution magnetic resonance imaging (HR-MRI) findings and clinical features of VAD with and without AIS. Methods Twenty-nine lesions from 27 patients (15 male and 12 female patients; age range = 28-73 years) who underwent diffusion MRI and 3T HR-MRI within seven days were included...

Background: Chronic subdural hematoma (CSDH) of the posterior fossa is uncommon in adults. Only a few cases have been reported, and most of these were secondary to head injury or anticoagulant therapy. We herein describe a case of successful surgical treatment of CSDH in the posterior fossa after surgical removal of a large supratentorial and infratentorial dermoid cyst. Case Description: A 71-year-old woman underwent removal of a left supratentorial and infratentorial dermoid cyst via a left transzygomatic approach...

BACKGROUND: Trastuzumab emtansine, an antibody-drug conjugate commonly abbreviated as T-DM1, is accepted as effective therapy for trastuzumab-resistant metastatic HER2-positive breast cancer. T-DM1 significantly increases progression-free and overall survival when compared with lapatinib plus capecitabine in patients with HER2-positive breast cancer previously treated with trastuzumab and a taxane. Among the common side effects related to T-DM1, thrombocytopenia and mucosal hemorrhage are seen, although they are infrequently judged to be clinically significant...

BACKGROUND AND PURPOSE: Spontaneous cerebellar intracerebral hemorrhage (ICH) has been reported to be mainly associated with vascular changes secondary to hypertension. However, a subgroup of cerebellar ICH seems related to vascular amyloid deposition (cerebral amyloid angiopathy). We sought to determine whether location of hematoma in the cerebellum (deep and superficial regions) was suggestive of a particular hemorrhage-prone small-vessel disease pathology (cerebral amyloid angiopathy or hypertensive vasculopathy)...

Objective: To observe the efficacy and safety of the novel oral anticoagulant Rivaroxaban for anticoagulation therapy in patients with nonvalvular atrial fibrillation (AF) during cryoablation. Methods: A total of 137 AF patients from October 2013 to December 2016 underwent cryoablation were divided into two groups according to the application of anticoagulant drugs: Rivaroxaban group (65 cases) and Heparin group (72 cases). Rivaroxaban group: oral administration of Rivaroxaban 20 mg, once a day, was started 3 days before the cryoablation, no anticoagulant was additionally added during cryoablation, the activated clotting time (ACT) was measured, and oral administration of Rivaroxaban was continued for 3 months after cryoablation...

BACKGROUND: An accurate diagnosis of isolated posterior inferior cerebellar artery dissection (iPICA-D) is difficult due to the limitation of spatial resolution on conventional magnetic resonance imaging (MRI) techniques to detect subtle vessel wall abnormalities. The recent development of MRI techniques, including high-resolution vessel wall imaging (HRVWI), has resulted in the improved diagnostic accuracy and efficiency of iPICA-D. In fact, T1-weighted HRVWI, which can reveal intramural hematomas in the posterior inferior cerebellar artery (PICA), is useful for the diagnosis of iPICA-D...

The incidence of spontaneous intracerebral hematoma (SICH) is even now high worldwide, especially higher in Japan than in Western countries, despite the development of advances in blood pressure (BP) management and food/alcohol intake education. Although mortality and morbidity for SICH are high, some controversies remain regarding the appropriate acute phase of treatment. Recent studies have revealed that BP lowering treatment than 140 mmHg resulted in better outcomes. However the efficacy of surgical treatment for SICH has not been well established, with the exception of that for cerebellar SICH over 3 cm in diameter and life-saving procedures, although many randomized control studies and systematic reviews focused on surgical treatment have been reported...

OBJECTIVE: Primary cerebellar hemorrhage accounts for 10% of all intracranial hemorrhages. Given the confined space of the posterior fossa, cerebellar hemorrhage management sometimes necessitates suboccipital decompression and hematoma evacuation. In this study, we examine outcomes after surgery for primary cerebellar hemorrhage and identify risk factors associated with adverse outcomes. METHODS: A retrospective review of the 2005-2014 American College of Surgeons-National Surgical Quality Improvement Program database was performed, with Current Procedural Terminology Code 61315 (suboccipital craniectomy or craniotomy for evacuation of cerebellar hemorrhage) queried between 2005 and 2014...

Metastatic brain tumor occasionally results in multiple cerebral hemorrhages. Here, we report a case of metastatic brain tumor complicated by multiple repeated cerebral hemorrhages. An 80-year-old man with a history of removal of lung cancer was admitted to our hospital because of disturbed consciousness following headache. A brain CT revealed a mass lesion of 40-mm diameter in the left cerebellum and a mass lesion of 2-mm diameter in the right temporal lobe. The cerebellar mass lesion showed homogeneous iso-density, indicating a subacute phase hemorrhage...

Cerebral venous thrombosis is a rare complication of intracranial hypotension. We describe 3 cases in which this phenomenon occurred, as a result of a lumbar puncture or due to a spontaneous cerebrospinal fluid leak. We emphasize the importance of early detection of the intracranial hypotension syndrome, the most common clinical manifestation being orthostatic headache. It is not an innocent condition as it is associated with other potential complications such as subdural hygroma/hematoma, cranial nerve palsies, cerebellar tonsillar descent, and even brainstem manifestations...

In 2010, a novel anti-neuronal autoantibody, termed anti-Ca, was described in a patient with subacute cerebellar ataxia, and Rho GTPase-activating protein 26 (ARHGAP26) was identified as the target antigen. Recently, three additional cases of anti-Ca-positive cerebellar ataxia have been published. In addition to ataxia, cognitive decline and depression have been observed in some patients. Here, we report two new cases of anti-Ca-associated autoimmune cerebellar ataxia. Patient 1 presented with dizziness and acute yet mild limb and gait ataxia...

We present a very rare variation of a persistent primitive hypoglossal artery (PPHA) arising from the internal carotid artery, detected during a diagnostic angiography. A 50-year-old female patient was admitted with an atypical intracranial hematoma in the left frontal lobe. Catheter angiography revealed intracranial vasculopathy with segmental stenoses, a small aneurysm of the right internal carotid artery bifurcation and a "string of beads" appearance of the left carotid artery, consistent with fibromuscular disease...
