Inflammatory pseudotumor is an uncommon lesion with unknown etiology characterized by sclerosing inflammation which clinically and radiographically mimics a neoplastic lesion. A 47-year-old man presented with sudden headache and dysarthria. Brain CT scan revealed a $2.6{\times}2.2\;cm$ sized, round, and hyperdense mass in the anterolateral wall of the left lateral ventricular trigone. On MR imaging studies, the mass showed low signal intensity in the wall of the trigone on T2-weighted image, central mixed (iso- and high-) signal intensity with peripheral low-signal intensity on T1-weighted image. Subtle staining of left choroid plexus with irregular shaped distal branch of anterior choroidal artery was found on the cerebral angiography. These findings suggested a small tumorous lesion originated from the left choroid plexus. During the hospital days, the mass manifested as repeated hemorrhages. The mass was successfully removed via left occipital transcortical approach. The histopathological report of the specimen was hemorrhage and fibrosis, with dense lymphoplasma cell infiltration, suggestive of an inflammatory pseudotumor.

Coarctation of the aorta is rare condition among the congenital cardiovascular defects in Korea. We experienced one case of coarctation of the aorta [postductal type], which was successfully corrected with Dacron graft. This 20 year old man was admitted to our hospital for evaluation of hypertension in the upper extremities and frequent occipital headache of 2 month duration. On physical examination, grade II systolic murmur was heard over the apex and mid back, but thrill was not palpable. Blood pressures were measured at both extremities, its values were 190/70mmHg. in the arms and 120/60mmHg in the legs. Routine chest roentgenogram showed the dilated left subclavian artery high on the left mediastinal border and associated with left ventricular prominence, but notchings of lower border of rib was not seen. Electrocardiogram also showed left ventricular hypertrophy. Final Pre-operative diagnosis was made by the aortic catheterization and aortography, which showed the typical configuration of postductal type of coarctation with poststenotic dilatation of aorta. Under the moderate hypothermia by surface cooling, coarcation was resected 3.5cm in length and then Dacron graft was inserted. After prosthetic correction, blood pressures were recorded 120/60mmHg in arms and 160/120mmHg in legs. The post-operative course was uneventful.

C1 lateral mass and C2 pedicle (C1LM-C2P) fixation is a relatively new technique for atlantoaxial stabilization. Complications from C1LM-C2P fixation have been rarely reported. The authors report unilateral rod migration into the posterior fossa as a rare complication after this posterior C1-C2 stabilization technique. A 23-year-old man suffered severe head trauma and cervical spine injury after vehicle accident. He was unconscious for 2 months and regained consciousness. He underwent C1LM-C2P fixation for stabilization of type II odontoid process fracture described by Harms. The patient recovered without a major complication. Twenty months after operation, brain computed tomogram performed at psychology department for disability evaluation showed rod migration into the right cerebellar hemisphere. The patient had mild occipital headache and dizziness only regarding the misplaced rod. He refused further operation for rod removal. To our knowledge, this complication is the first report regarding rod migration after Harms method. We should be kept in mind the possibility of rod migration, and C1LM-C2P fixation should be performed with meticulous technique and long-term follow-up.

A 34 year old male patient visited to our neuro-pain clinic with symtoms of a left frontal headache, eyeball throbbing and occipital pain. Two days after the first visit to our clinic. pain was aggrevated and the skin eruption appeared on the left forehead. He was diagnosed as raving Herpes Zoster Opthalmicus(HZO). We performed stellate ganglion block(SGB), but pain did not subsid. So a continuous cervical epidural block was perfomed(CCEB) and it could relieve the pain promptly. In this case, VAS(visual analogue scale) was diminished from 10 to 3 and the skin eruption was healed 24 days after the treatment with CCEB and SGB. We experienced that CCEB is more effective rather than intermittent SGB in intractable HZO. CCEB should be considered to the treatment of choice in patients with HZO.

We report a chronic cerebral paragonimiasis from a 41-year-old Korean man who complains a headache and weakness of left motor neuron components. Magnetic resonance images of the brain revealed conglomerates of multiple ring-like enhancements in tempore-occipital and frontal lobes of the right hemisphere. An intradermal test for paragonimiasis westermani was positive. The patient was born near an endemic area of paragonimiasis and used to eat boiled or grilled freshwater crayfish in his childhood. Nodules in the brain were resected through craniotomies. The eggs of P. westemani were identified pathologically and parasitologically in the calcified necrotic lesions. Examinations on sputum and fecal specimens for the eggs of P. westemani were shown to be negative and a chest radiograph was normal. It is presumed that the brain lesions were formed by P. westemani approximately 30 years ago.

Blunt cerebrovascular injury is defined as a vertebral or carotid arterial structural wall injury resulting from nonpenetrating trauma. Complete traumatic internal carotid artery occlusion is very rare condition accounting for 0.08~0.4 0f all trauma patients and believed to be associated with the greatest risk of ischemic stroke reported in 50~90% in a few small series. A 55-year-male was admitted with drowsy mentality and severe headache after a fall down accident. Brain computed tomography showed a subdural hematoma at the both frontal area with a fracture of the occipital skull bone. Two days after admission, he suddenly complained with a right side hemiparesis of motor grade 2. Brain magnetic resonance diffusion demonstrated multiple high flow signal changes from the left frontal and parietal lesion. Computed tomographic angiogram (CTA) revealed absence of the left ICA flow. Trans femoral cerebral angiography (TFCA) showed complete occlusion of the left internal carotid artery (ICA) at ophthalmic segment in the left ICA angiogram and flows on the left whole hemispheric lesions through the anterior communicating artery in the right ICA angiogram. We decided to conduct close observations as a treatment for the patient because of acute subdural hematoma and sufficient contralateral cerebral flow by perfusion SPECT scan. Two weeks after the accident, he was treated with heparin anticoagulation within INR 2~4 ranges. He recovered as the motor grade 4 without another neurologic deficit after 3 months.

Germinoma associated with chronic granulomatous inflammation of pineal gland has been rarely reported in the literature. The mechanism of chronic granulomatous inflammation is not understood well. We report a case of chronic granulomatous inflammation in pineal germinoma. In a 17 year-old male who suffered from headache and diplopia for six months, the mass of pineal gland was detected by brain MRI and removed through occipital transtentorial approach. The pathological specimen revealed the mass was predominantly composed of chronic granulomatous inflammation associated with small portion of germ cell tumor nests In the pathological interpretation of chronic granulomatous inflammation of pineal mass, it would be obliged to search for the presence of germ cell component.

가상현실 기술이 발전하면서 다양한 영역에서 여러 목적으로 활용되고 있다. 하지만 사용자로부터 메스꺼움, 어지러움 등과 같은 멀미 증상에 대한 부작용도 함께 보고되고 있다. 이런 멀미 증상을 사이버멀미라고 말하며, 사용자에게 불편을 야기시켜 불쾌감과 스트레스와 같은 부정적 영향을 줄 수 있으며, 현재 사이버멀미의 발생 원인과 해결책에 관한 공식적인 표준이 없다. 본 연구에서는 이런 한계점을 극복하기 위해 정량적, 객관적 사이버멀미 평가법을 제안하였다. 10명의 20대 남성 대상으로 이동과 회전을 하는 가상현실을 경험하게 하면서 128채널의 뇌파를 측정하였다. 11개 영역에서 Delta와 Alpha 상대 파워를 계산하고, ROC curve를 통해 area under the ROC curve (AUC)가 가장 높은 값을 가지는 다중회귀모형을 도출하였다. 이렇게 도출한 다중회귀모형은 11개의 설명변수로 피험자가 응답한 사이버멀미의 정도와 비교하여 95.1 % (AUC = 0.951)의 정확성으로 사이버멀미를 구분하는 것이 가능함을 알 수 있었다. 이러한 결과를 정리하면 본 연구에서는 128 채널의 뇌파를 통해 멀미에 대한 객관적 반응을 확인하였으며, 뇌의 특정부위에서 반응이 있는 것으로 나타났다. 본 연구 결과와 분석법을 활용하면 추후 사이버멀미 관련 연구에 도움이 될 수 있을 것으로 기대된다.
