Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source.

Clear cell ependymomas (CCEs) are rare variants of ependymomas. Tumors show anaplastic histological features and behave as an aggressive manner. CCEs have a predilection for extraneural metastases and early recurrence, and they demonstrate characteristic radiographic features. These tumors should be radiologically and pathologically differentiated from oligodendrogliomas. On microscopic examination, CCEs are composed of sheets of cells and resemble oligodendroglioma. However, upon closer examination, the nature of CCEs can be detected earlier, resulting in prompt treatment of the tumor. Although we report only one case, we emphasize the importance of early diagnosis and treatment. Future description of more cases of these rare cancers is necessary to aid in their diagnosis and treatment.

Lumbar spinal stenosis (LSS) is a common spinal disease in the elderly. The cardinal symptom of LSS is neurogenic claudication, but not all patients present with such typical symptom. The clinical symptoms are often confused with symptoms of peripheral neuropathy, musculo-skeletal disease and other medical conditions in elderly patients. In particular, LSS presenting with rapid progression of leg weakness must be distinguished from other combined diseases. We report a case of rapid progressive leg weakness in a patient with LSS and iatrogenic adrenal insufficiency that was induced by obscure health supplement.

Osteolipoma is an ossified lipoma with distinct components of fat and bone. We present a case of interhemispheric osteolipoma associated with total agenesis of the corpus callosum. A 20-year-old man complained of severe headache, nausea and vomiting. Brain computed tomography showed a low-density mass in an interhemispheric fissure, with high T1 and T2 magnetic resonance signals compatible with fat. The mass measured 4.9 x 2.9 cm in size and showed peripheral calcifications. There was another small piece of same signal mass within the lateral ventricular choroid plexus. The interhemispheric lesion was removed by an interhemispheric approach. Osteolipoma is rare in interhemispheric region, however, it should be a differential diagnosis of lesions with fat intensity mass and calcifications.

Arteriovenous malformations (AVM) are generally considered to be cured following angiographically proven complete resection. However, rare instances of AVM recurrence have been reported in both children and adults with negative findings on postoperative angiography. The authors present the case of a 12-year-old boy with recurrent AVM. The AVM was originally fed by the pericallosal arteries on both sides, and it showed changing patterns of supply at recurrence. The authors concluded that a negative postoperative angiogram is not necessarily indicative of a cure. Repeat angiography and regular follow-up examinations should be performed to exclude the possibility of recurrence, especially in children.

Langerhans' cell histiocytosis (LCH) is a rare immunologic disorder characterized by histiocyte proliferation in multiple organ systems. Eosinophilic granuloma, a benign bone lesion, represents a focal form of LCH. We experienced a case of Langerhans' cell histiocytosis in a patient who presented with intracranial epidural hematoma and cyst on the midline of the frontal skull. A 10-year-old boy presented with a rapidly growing large scalp mass on the midline frontal area after mild head trauma. The scalp mass was painless and immobile. Plain skull x-ray showed a punched-out bone lesion. Computed tomography and magnetic resonance imaging showed a non-enhancing osteolytic lesion presenting with an epidural hematoma and cyst on the midline of the frontal skull. The lesion of the skull was completely resected and the patient's recovery was uneventful. The acute presentation of a solitary eosinophilic granuloma of skull with an epidural hematoma has been described in only five cases in the literature and we report the first case of LCH presenting as an intracranial epidural hematoma on frontal area.

BACKGROUND: In Korea, cerebrovascular accident (CVA) is the most significant cause of death among older people, and the incidence of cerebral hemorrhage is much higher than that of developed countries. There have been many investigations about the risk factors for CVA in both Korea as well as developed countries. A few papers reported various risk factors for cerebral hemorrhage in developed countries:however, well-designed studies of risk factors for the various causes of CVA were rare in Korea. Therefore, the purpose of this study was to compare the risk factors for the various causes of CVA and to evaluate the risk factors compared with age- and sex-matched control groups. In addition, duplex sonographic findings of the carotid artery were evaluated in patients with cerebral infarction. METHODS: One hundred and sixty-four patients admitted to the hospital in 1996 were enrolled. The four groups were divided based on the following states: cerebral infarction (n-63), cerebral hemorrhage (n-64), cerebral infarction with atrial fibrillation (n-19), and lacunar infarction (n-18). Major risk factors were compared with age- and sex-matched control groups and among CVA groups. Duplex sonography of the carotid artery was done in 14 patients with cerebral infarction. RESULTS: In multiple logistic regression analysis, patients with cerebral infarction had higher prevalence of diabetes mellitus and lower high density lipoprotein-cholesterol level than the control group, and hypertension showed borderline significance. Patients with cerebral hemorrhage had higher prevalence of hypertension, higher high density lipoprotein-cholesterol level, and more frequent prevalence of smoking compared with the control group. Patients with cerebral infarction showed lower high density lipoprotein-cholesterol, higher low density lipoprotein-cholesterol levels, more frequent diabetes mellitus, lower prevalence of hypertension and older age than patients with cerebral hemorrhage. Patients with cerebral infarction and atrial fibrillation showed only older age than patients with cerebral infarction only. There were no differences in risk factors between patients with cerebral infarction and lacuna infarction. Atheromatous plaque was found in 71% of patients with cerebral infarction. CONCLUSION: Metabolic abnormalities played more important role in the development of cerebral infarction and hemodynamic abnormalities in cerebral infarction. Sonographic examination of the carotid artery may be useful for predicting the occurrence of cerebrovascular accident in high risk patients.

Embolization of intracranial arteriovenous malformations has been mainly used for palliation of symptom, for preoperative management, or for patients who have large sized AVM planned for radiosurgery. But, it can be used as a sole, effective treatment modality in some selected cases. However, there have been many controversies about its completeness. Over the past 10 years, the authors experienced two cases of patients who have suffered from a recurrences of AVMs after embolization. The authors reviewed the literatures concerning about the recurrence of AVM after embolization and postulated the causes for recurrences of our two cases. In our opinions, complete embolic obliteration of cerebral AVM is impossible in most cases and embolization must not be used as a sole treatment modality of cerebral AVM.
