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...

Among the intracranial hematomas, chronic subdural hematomas (CSDH) are the most benign with a mortality rate of 0.5-4.0%. The elderly and alcoholics are commonly affected by CSDH. Even though high percentage of CSDH patients improves after the evacuation, there are some unexpected potential complications altering the postoperative course with neurological deterioration. Poor outcome in postoperative period is due to complications like failure of brain to re-expand, recurrence of hematoma and tension pneumocephalus...

BACKGROUND AND IMPORTANCE: Formation of cavernous malformations (CMs) has been recognized to be associated with developmental venous anomaly (DVA) by many authors. Hemodynamic stress due to venous outflow restriction could be hypothesized as a cause. On the other hand, a rare subgroup of DVA with an arterial component has been reported as likely to hemorrhage or be symptomatic. Cases of arterialized DVAs reported previously have not been associated with the presence of CM. CLINICAL PRESENTATION: We present herein a case report of arterialized DVA in the brainstem with repeated cerebellar hemorrhage...

A man in his late forties had lived as a recluse for more than ten years. He was found dead in his room. At autopsy, subarachnoid hemorrhage (SAH) was detected at the base of the brain, which weighed 1333 g. The cerebellar tonsil was swollen. The cerebral ventricle was enlarged and filled with blood. A hematoma was observed in the upper part of the left side of the cerebellar hemisphere. The location and size of SAH in this case indicated that the rupture of a cerebral aneurysm (CA) had occurred; however, CA was not detected...

BACKGROUND Cerebellar hemorrhage (CH) has a quite different treatment strategy and prognostic factors compared with supratentorial intracerebral hemorrhage (ICH). The prognostic role of hyperglycemia has been discussed mainly in cases of supratentorial hemorrhage; it remains to be elucidated following CH. We aimed to determine the association of hyperglycemia on admission with 6-month functional outcome in CH patients. MATERIAL AND METHODS We retrospectively analyzed 77 patients with acute CH between September 2010 and April 2015 in West China Hospital...

REVIEW
Fei Yang, Jianning Zhao, Haidong Xu
Hemorrhagic stroke can occur after spine and joint surgeries such as laminectomy, lumbar spinal fusion, tumor resection, and total joint arthroplasty. Although this kind of stroke rarely happens, it may cause severe consequences and high mortality rates. Typical clinical symptoms of hemorrhagic stroke after spine and joint surgeries include headache, vomiting, consciousness disturbance, and mental disorders. It can happen several hours after surgeries. Most bleeding sites are located in cerebellar hemisphere and temporal lobe...
