Objectives : To evaluate the association between body mass index (BMI) and hemorrhagic stroke. Methods : A case-control study was conducted on 2,712 persons (904 cases, 904 hospital controls, and 904 community controls) participating in an Acute Brain Bleeding Analysis study from October 2002 to March 2004. Two controls for each case were matched according to age and gender. The information was obtained by trained interviewers using standardized questionnaire. A conditional logistic regression model was used to estimate the association between BMI and the frequency of having a hemorrhagic stroke. Results : Obese men (25.0 $\leq$ BMI < $30.0\;kg/m^2$) had an odds ratios (OR) of 1.39 (95% CI 1.03 to 1.87) a hemorrhagic stroke, compared to men with a normal BMI (18.5 to $24.9\;kg/m^2$). Conversely, women with lower BMI had a higher risk of having hemorrhagic stroke. With respect to subtypes of hemorrahagic stroke, we observed about a three-fold increase in the risk of intracerebral hemorrhage (ICH) in the highly obese group. However, these trends were not significant in patients with subarachnoid hemorrhages. Conclusions : Obesity was identified as one of the risk factors in hemorrhagic stroke, in particular ICH. Conversely, in women, a lean body weight increases the risk of hemorrhagic stroke. Consequently, managing one's weight is essential to reduce the risks of hemorrhagic stroke.

Fever is an elevation of body temperature to a level above normal to greater than $37.2^{\circ}C$. Fever of Unknown Origin is usually defined in adults as continuous fever at least 3 weeks duration with daily temperature elevation above $101.5^{\circ}F(38.3^{\circ}C)$ and remaining undiagnosed after 1 week of intensive study in the hospital. Diagnoses for Fever of Unknown Origin fall into three general categories: infectious disease, connective tissue disease, neoplasm. We experienced a cases of Fever of Unknown Origin which occurred after subarachnoid hemorrhage and intracerebral hemorrhage. As for treatment, we used Cheongleejagamtang-gami(淸離滋坎湯加味). Fever of Unknown Origin was improved within 5 days of the admission.

Moyamoya disease is defined as the development of collateral pathways, associated with bilateral chronic progressive stenosis of the carotid fork. Persistent trigeminal artery is the vessel most frequently observed to persist into adult life among persistent carotid-basilar and carotid-vertebral anastomotic vessels. The authors present a man who had a sudden, severe headache and brain CT showed subarachnoid hemorrhage in left interpeduncular and prepontine cistern. Four-vessel angiogram revealed moyamoya disease associated with aneurysm arising from the junction of persistent trigeminal artery aneurysm and basilar artery. As a treatment, coil embolization was tried but it was failed because of anatomical difficulty of aneurysm. The aneurysm was successfully treated with clipping surgery 10 days later. To our knowledge, this is the first case being reported.

Objective : To investigate nationwide statistics on flow-diverting stent usage for cerebral aneurysm treatment and related mortality data. Methods : We requested data extraction from the National Health Insurance Service claims database using electronic data interchange codes (J3207064, J3207073). Patient and hospital information as well as death statistics were collected from the database. Results : A total of 169 procedures were performed using flow-diverting stents for cerebral aneurysm treatment from November 2014 to December 2016 in Korea. The majority of primary diagnosis was unruptured intracranial aneurysm. During the study period, nine subjects died, including one patient initially diagnosed with subarachnoid hemorrhage. The crude mortality rate was 5.3%. Five patients died within one month after the procedure; therefore, the estimated periprocedural mortality rate was $3.0{\pm}1.3%$. The mortality rate as of the last day of 2016 was $6.3{\pm}2.1%$. Conclusion : In a 171 person-year follow-up in a Korean series, nine deaths occurred after flow-diverting stent treatment. The crude mortality rate in Korea (5.3%) was higher than that reported in a previous meta-analysis (3.8%).

Granulomatous meningoencephalomyelitis (GME) is a sporadic, idiopathic, non suppurative inflammatory disease of the canine central nervous system. GME appears to have a worldwide distribution and to occur mostly in young to middle-age dogs of small breeds. A 6-year-old female mixed dog with wry neck, ataxia and rolling was submitted to the Cheju National University for diagnosis. Grossly, in the brain, cerebrospinal fluid was mildly increased and dilatation of the subarachnoid blood vessels was observed. Histopathologically, the lesions were characterized by perivascular cuffs of lymphocytes, various numbers of macrophages and plasma cells in the brainstem and cerebral white matter. Numerous granuloma composed of lymphocytes and histiocytes were scattered throughout the brainstem. Two malacic foci characterized by axonal swelling and gitter cell infiltration with hemorrhage were noted in the medulla oblongata and cerebellum. Special stains failed to demonstrate any infectious agents. Immunohistochemically, the infiltrated cells demonstrated strong positive reactions for CD3, a marker for T lymphocytes origin. Based on the clinical signs, histopathology, and immunohistochemistry, this case was diagnosed as GME in a mixed dog.

Systemic multiple aneurysms are rare, and an association between intracranial and visceral arterial or abdominal aortic aneurysm in the same patient is a very rare occurrence. We report herein three such cases. In one case, aneurysms of the right internal carotid artery(ICA) and the right middle cerebral arterial bifurcation(MCAB) coexisted with the inferior pancreaticoduodenal arterial pseudoaneurysm and two ileal arterial aneurysms. In another case, the patient had the A-com arterial aneurysm and the right renal arterial aneurysm. And in the other patient, he had the right vertebral artery dissecting aneurysm with the abdominal aortic aneurym. Initially, all patients were referred to our hospital with subarachnoid hemorrhage(SAH), and thereafter first two patients developed visceral arterial aneurysm rupture in the course of hospital stay and in the last patient, the abdominal aortic aneurysm was detected incidentally during carotid angiogram for Guglielmi detachable coil(GDC) embolization of vertebral dissecting aneurym. After thorough review of our cases together with pertinent literatures, we emphasize the possibility of underlying extracranial aneurysms in ruptured intracranial arterial aneurysm patient and it's uncommon but fatal complication.

We report an unusual case of lateral medullary infarction after successful embolization of the vertebral artery dissecting aneurysm (VADA). A 49-year-old man who had no noteworthy previous medical history was admitted to our hospital with a severe headache. Computed tomography (CT) revealed a subarachnoid hemorrhage, located in the basal cistern and posterior fossa. Cerebral angiography showed a VADA, that did not involve the origin of the posterior inferior cerebellar artery (PICA). We treated this aneurysm via endovascular trapping of the vertebral artery distal to the PICA. After operation, CT revealed post-hemorrhagic hydrocephalus, which we resolved with a permanent ventriculoperitoneal shunt procedure. Postoperatively, the patient experienced transient mild hoarsness and dysphagia. Magnetic resonance image (MRI) showed a small infarction in the right side of the medulla. The patient recovered well, though he still had some residual symptom of dysphagia at discharge. Such an event is uncommon but can be a major clinical concern. Further investigation to reveal risk factors and/or causative mechanisms for the medullary infarction after successful endovascular trapping of the VADA are sorely needed, to minimize such a complication.

Objective : Stent-assisted coiling on intracranial aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. To achieve reconstruction of intracranial vessels with preservation of parent artery the use of stents has the greatest potential for assisted coiling. We report the results of our experiences in ruptured wide-necked intracranial aneurysms using Y-stent coiling. Methods : From October 2003 to October 2011, 12 patients (3 men, 9 women; mean age, 62.6) harboring 12 complex ruptured aneurysms (3 middle cerebral artery, 9 basilar tip) were treated by Y-stent coiling by using self-expandable intracranial stents. Procedural complications, clinical outcome, and initial and midterm angiographic results were evaluated. The definition of broad-necked aneurysm is neck diameter over than 4 mm or an aneurysm with a neck diameter smaller than 4 mm in which the dome/neck ratio was less than 2. Results : In all patients, the aneurysm was successfully occluded with no apparent procedure-related complication. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. Follow-up studies showed stable and complete occlusion of the aneurysm in all patients with no neurologic deficits. Conclusion : The present study did show that the Y-stent coiling seemed to facilitate endovascular treatment of ruptured wide-necked intracranial aneurysms. More clinical data with longer follow-up are needed to establish the role of Y-stent coiling in ruptured aneurysms.

Objective : Aneurysms are very rarely encountered in the distal posterior inferior cerebellar artery (PICA). The authors experienced 5 cases with a distal PICA aneurysm among 368 cases of intracranial aneurysms during the period from January 2003 to January 2008. Here, the authors describe their clinical and surgical experiences and include a review of the relevant literature. Methods : Using radiologic findings and charts, we retrospectively reviewed the surgical results of 5 cases with a distal PICA aneurysm treated from January 2003 to January 2008. Results : The current five cases were composed of four cases of 'Good' and one case of 'Fair'. No postoperative complications occurred other than a ventriculo-peritoneal shunt due to hydrocephalus in Case 2. In all five cases, treatment was successful without neurological deficit. Conclusion : Surgical outcome of PICA aneurysms have been reported to be excellent because the amount of intraparenchymal injury is limited. More clinical experience, microsurgical technique developments, and endovascular surgery advancements are certain to improve treatment outcomes.

Accessory middle cerebral artery (MCA) is an infrequent vascular anomaly of the brain. Cerebral aneurysms associated with this anomalous artery are also very rare. To our knowledge, there have only been ten previous reports of an aneurysm associated with accessory MCA. The authors present two patients with accessory MCA-related aneurysms. A 38-year-old male and a 59-year-old female both presented with sudden-onset severe headache. In both patients, computed tomography (CT) scan revealed subarachnoid hemorrhage. A subsequent angiogram demonstrated an accessory MCA arising from the anterior cerebral artery (ACA) and a saccular aneurysm at the anterior communicating artery (ACoA) complex associated with an accessory MCA. Surgical clipping allowed for complete exclusion of the aneurysm from the arterial circulation. Based on our review of the ten cases of aneurysms associated with accessory MCA documented in the literature, we suggest that accessory MCA-related aneurysms can be classified according to whether the accessory MCA originates from the proximal A1 segment or from the ACoA complex. We also emphasize the importance of precise interpretation of preoperative angiograms and intraoperative precaution in determining the presence of this anomalous artery prior to temporary clip placement.
