Intracranial pial arteriovenous fistulas (AVFs) are rare cerebrovascular lesions. The authors report a case of pediatric AVF treated by direct disconnection with the aid indocyanine green (ICG) videoangiography. A 3-year-old girl presented developmental problems. Magnetic resonance imaging revealed brain atrophy and an anomalous left temporal vascular mass. Angiography showed high-flow in early arterial phase fed M1 portion middle cerebral artery draining into superficial sylvian vein...
Intracranial meningioma with intratumor metastasis have been occasionally reported. However, to our knowledge, there are almost no reports of malignant tumors initially discovered due meningioma. A 74-year-old woman presented amnesia. Magnetic resonance imaging showed a well-defined mass arising from falcotentorial junction and homogeneous enhancement. Histopathologic findings that the was meningothelial meningioma, majority tumor cells propagating in sheets, however, single area tissue...
Abstract The aim of this study was to assess clinical outcomes using linac-based, fractionated, stereotactic radiotherapy (fSRT) with a micro-multileaf collimator for large brain metastasis (LBM) unsuitable surgical resection. Between January 2009 and October 2018 we treated 21 patients LBM linac-based fSRT. defined as tumor ≥30 mm maximal diameter in gadolinium-enhanced magnetic resonance images. LBMs originated from the lung (n = 17, 81%), ovary 2, 9.5%), rectum 1, 4.8%) esophagus 4.8%)....
Purpose: As stereotactic radiotherapy (SRT) becomes widespread, precise information including number, location, and margin of lesions is required when magnetic resonance (MR) imaging brain metastasis performed. We compare methods using 2 separate injections a single injection for the administration double dose contrast medium contrastenhanced MR imaging.Materials Methods: divided 40 patients with into groups 20 patients. Group A received (0.2 + 0.2 mL/kg) (gadoteridol); B same total (0.4...
There has been a reluctance to perform percutaneous ethanol injection therapy on lesions located the surface of liver because possibility complications. We treated 16 in 14 patients by and evaluated complications efficacy. Bleeding seeding malignant cells did not occur any case. However, transient pain after was more intense these than those whose were liver. Histopathologic examinations, imaging findings, decrease serum alpha-fetoprotein levels showed that effective for tumors Our...
Abstract To investigate the changes in vegetation, soil profile morphology, and some chemical properties of soils under different conditions forest decline, six representative study sites were set up on Mt. Hirugatake, Tanzawa Mountains, Kanto district, Japan, where serious decline had been observed since 1970s for broadleaved deciduous trees. The selection degrees was based interpretation vegetation aerial photographs taken 1947, 1967, 1977, 1993, also surveys at around selected sites....
It is mandatory to develop microsurgery training methods for young neurosurgeons because the number of surgical cases has been decreasing due development alternative therapy neurovascular diseases such as radiosurgery, endovascular coil embolization, and stenting. Here we describe our microvascular anastomosis well senior staff with minimum cost maximum convenience. Our microsurgical system consists microanastomosis using an artificial tube actual microscope in operating room. The depth size...
Central neurocytomas (CNs) are rare intraventricular tumors that well demarcated and display neuronal differentiation. This tumor type is most frequently diagnosed in young adults typically located at the septum pellucidum fornix, presents with intracranial hypertension due to obstructive hydrocephalus. Extraventricular (EVNs) biological histopathological characteristics similar CNs, but which arise from extraventricular parenchymal tissue (Giangaspero et al., 1997) Giangaspero al. (1997)...
The authors report a rare case of an anterior sacral meningocele (ASM) associated with epidermoid cyst, manifesting as increasingly enlarged subcutaneous mass in the gluteal region. A 66-year-old male presented pygal lesion. Plain radiographs and three-dimensional computed tomography (CT) demonstrated scimitar defect sacrum. Magnetic resonance images (MRI) revealed two cystic components presacral region, which appeared to be continuous dural sac. Subsequent laminectomy, exploration ostium...
Surgical treatment of the cerebral arteriovenous malformations (AVMs) is one most difficult neurosurgical practices, because neurosurgeons may not get adequate practice operating on patients with AVMs and variation characteristics these lesions makes it to establish a standard technique skill effectively resect complicated vascular tangles in brain parenchyma. However, mandatory for any neurosurgeon manage AVM who present severe neurological deficits or moribund condition due hemorrhage....
sylvian fissureの十分な剝離は，未破裂脳動脈瘤を安全かつ確実にclipするために必要不可欠である．われわれは，特に吸引管による脳のretractionを意識しながらsylvian fissureの剝離を行っており，その方法を報告する．吸引管を脳のretractorとして使用する際にretractionする吸引管の強さ（tension）と方向（direction），つまりベクトル（vector）を意識することが重要である．吸引管を用いて脳を適切な強さ（tension）と方向（direction）〔適切なベクトル（vector）〕で圧排することにより，くも膜や微細な血管の視認性が高まりくも膜の切離を容易にすると同時に，脳圧排による挫傷や血管損傷を最小限にすることができる．sylvian fissureの十分な剝離は広い術野をつくり出し，結果的にclipping操作も行いやすくなると考える．
