Hayri Ogul, Mecit Kantarci
Cerebral arteriovenous malformation (AVM) is a common type of cerebral vascular malformation. The imaging findings are enlarged vessels, thrombosed sinuses, and hemorrhage or gliosis on adjacent brain parenchyma. Magnetic resonance (MR) imaging can be used safely for diagnosis. Chiari type I malformation is characterized by a caudal descent of the cerebellar tonsil. Coincidence of cerebral AVM and Chiari type I malformation is very rare. In this paper, the authors report MR imaging findings of a patient with coincidence of cerebral AVM and Chiari type I malformation...

BACKGROUND: Superior cerebellar artery (SCA) aneurysms are usually grouped with aneurysms that arise from the upper basilar artery or more broadly, the posterior circulation. However, the SCA aneurysm has distinctive anatomy that facilitates safe surgical management, notably few associated perforating arteries, and excellent exposure in the carotid-oculomotor triangle. OBJECTIVE: To demonstrate the outcomes of patients treated with microsurgery in a continuous surgical series...

Taste(gustation)is one of the five senses, and comprises the types: sweet, bitter, salty, sour, and umami. Taste disorders, such as dysgeusia and parageusia, are classified into 2 types: those with peripheral origin and those with central origin. The peripheral origin-type taste disorder is caused by zinc deficiency, mouth dryness, a side effect of radiotherapy or complication of systemic diseases such as, diabetes, hepatopathy, and nephropathy. The central origin-type taste disorder is reported to be caused due to demyelinating disease, pontine hemorrhage, pontine infarction, and thalamic infarction; it is very rarely caused by a brain tumor...

The authors report a case of a developmentally normal child with a congenital complex torcular dural arteriovenous fistula (DAVF) who later, in his teenage years, developed several vermian cavernomas within a large cerebellar developmental venous anomaly (DVA). The patient had initially presented with an abnormally large head circumference but no neurological deficits. He underwent several partial embolization procedures in an attempt to decrease the blood supply of the fistula over the course of 8 years. Nine years following initial presentation, he presented with a fourth ventricular hemorrhage, due to development of a new vermian cavernoma adjacent to a previously known vermian DVA and suffered subsequent mild left-sided hemiataxia from which he later recovered...

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...

BACKGROUND: Acute cerebrovascular accident (CVA) is a devastating cause of patient morbidity and mortality. Up to 10% of acute CVAs in young patients are caused by dissection of the vertebral or carotid artery. Wallenberg syndrome results from a CVA in the vertebral or posterior inferior artery of the cerebellum and manifests as various degrees of cerebellar dysfunction. The administration of a thrombolytic medication has been recommended in the treatment of patients with stroke caused by cervical artery dissection...

The claudin family comprises four-pass transmembrane proteins involved in the formation of tight junctions (TJs). Relatively recently, claudin domain containing (CLDND) 1, also known as claudin-25, was identified as a novel member of the claudin family. In the present study, we revealed that in the adult murine brain, CLDND1 is abundant in the cerebellum among common sites of intracerebral hemorrhage. Thus, the dynamics of CLDND1 after cerebellar hemorrhage were examined. Both CLDND1 mRNA and protein levels transiently decreased at 24 hr after hemorrhagic insult...

OBJECTIVE: Spontaneous cerebellar hemorrhages (SCH) can lead to life-threatening complications with high mortality rates of 20-50%. Although complications of SCH can be prevented by surgical therapy, there is a lack of consensus concerning the optimal surgical technique for evacuating SCH. METHODS: In this retrospective study 85 patients with SCH were divided into four treatment groups: (1) Decompression and Hematoma Evacuation via suboccipital craniectomy and removal of the posterior arch of C1 (DHE)...

OBJECTIVE: Many new endovascular devices have been used under the guidance of the International Subarachnoid Aneurysm Trial (ISAT). Clipping still offers higher occlusion rates, and its technique continues to evolve, resulting in smaller exposures and reduced manipulation to brain tissue. We sought to evaluate the routine use of the minisphenoidal approach to manage intracranial aneurysms in a high-volume institution. METHODS: We retrospectively reviewed our database of aneurysm patients from October 2013 to May 2016...

INTRODUCTION: We report the changes in cortical activity evaluated using functional near-infrared spectroscopy (fNIRS) in 2 cases with cerebellar stroke. METHODS: Using an fNIRS imaging system, changes in the oxygenated hemoglobin concentration (ΔOxy-Hb) from baseline were estimated. Design and verbal fluency tasks were conducted for evaluation of visuospatial and language functions, respectively. RESULTS: The contralateral prefrontal area showed limited activation compared with the ipsilateral one in the case with either cerebellar stroke...

OBJECTIVE: Randomized trials support carotid endarterectomy (CEA) in asymptomatic patients with ≥60% internal carotid artery (ICA) stenosis. The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Our goal was to determine the natural history stroke risk of asymptomatic patients who might have undergone CEA based on consensus statement PSV of ≥230 cm/s but instead were treated medically based on more conservative CDUS imaging criteria...

Most ischemic strokes are managed on the ward or on designated stroke units. A significant proportion of patients with ischemic stroke require more specialized care. Several studies have shown improved outcomes for patients with acute ischemic stroke when neurocritical care services are available. Features of acute ischemic stroke patients requiring intensive care unit-level care include airway or respiratory compromise; large cerebral or cerebellar hemisphere infarction with swelling; infarction with symptomatic hemorrhagic transformation; infarction complicated by seizures; and a large proportion of patients require close management of blood pressure after thrombolytics...

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...

Infratentorial cerebral hemorrhage due to a direct carotid-cavernous fistula (CCF) is very rare. To our knowledge, only four such cases have been reported. Cerebellar hemorrhage due to a direct CCF has not been reported. We describe a 63-year-old female who presented with reduced consciousness 3 days after undergoing a maxillectomy for maxillary cancer. Computed tomography showed a cerebellar hemorrhage. Magnetic resonance angiography showed a left-sided direct CCF draining into the left petrosal and cerebellar veins through the left superior petrosal sinus (SPS)...

BACKGROUND: Behcet's disease is a heterogeneous, multisystem, inflammatory disorder of unknown etiology. The classic triad of oral and genital ulcerations in conjunction with uveitis was originally described by the Turkish dermatologist Hulusi Behcet in 1937, but associated symptoms of the cardiovascular, central nervous, pulmonary, and gastrointestinal systems were later identified. In fact, Behcet's disease with neurological involvement (neuro-Behcet's disease) is not uncommon. Patients with neuro-Behcet's disease typically exhibit a diverse array of symptoms, most commonly in the brainstem and diencephalic regions...

RATIONALE: We examined injuries of the dentato-rubro-thalamic tract (DRTT), cortico-ponto-cerebellar tract (CPCT), dorsal spinocerebellar tract (SCT), and inferior cerebellar peduncle (ICP) in a patient with severe ataxia following bilateral tegmental pontine hemorrhage (PH), using diffusion tensor tractography (DTT). PATIENT CONCERNS: A 75-year-old female patient underwent conservative management for bilateral tegmental PH. She presented with moderate motor weakness, severe resting and intentional tremor on both hands, and severe truncal ataxia (Scale for Assessment and Rating of Ataxia [25 points/0-40 points: a higher score indicates a worse state]), and she was not able to sit independently...
