Kimura's Disease of the Orbit Successfully Treated with Radiotherapy Alone: A Case Report.

We performed radiotherapy in a 28-year-old patient with Kimura's disease of the orbit. Irradiation with 21.6 Gy was administered to the tumor bed with a single dose of 1.

Prognostic significance of expression patterns of EGFR family, p21 and p27 in high-grade astrocytoma.

The goal of this study was to investigate the relationship among immunohistochemical expression of epithelial growth factor receptor (EGFR) family proteins, p21, p27 and prognosis in patients with high-grade astrocytoma. Expression of EGFR family proteins (c-erbB-1, c-erbB-2, c-erbB-3, c-erbB-4), p21 and p27 and Ki-67 labeling index (LI) were studied in 59 samples of high-grade astrocytoma. Expression of protein levels was analyzed by immunohistochemical staining of formalin-fixed and paraffin-embedded sections.

Cerebral sinovenous thrombosis after closed head injury.

Background: Cerebral sinovenous thrombosis (CSVT) after closed head injury is an uncommon but potentially serious complication. The aim of this study was to determine whether diffusion weighted imaging (DWI) provide predictive information regarding prognosis.

Methods: We retrospectively reviewed a series of 11 patients with CSVT after closed head injury.

Primary angiitis of the central nervous system mimicking dissemination from brainstem neoplasm: a case report.

Background: Diagnosis of PACNS is very difficult because of the variety of clinical manifestation, especially neurologic and MRI findings. We report the case of a 68-year-old woman with PACNS.

Case Description: Her clinical symptoms mimicked malignant brainstem neoplasm disseminated to third and fourth ventricles and cervical spinal cord.

Local administration of amphotericin B against aspergilloma in the prepontine cistern--case report.

A 21-year-old man presented with aspergilloma in the prepontine cistern that developed after treatment for cerebellar hematoma following rupture of an arteriovenous malformation. He became bedridden with neurological signs of tetraparesis, disturbed ocular movement, and bulbar palsy, despite alert consciousness. Repeat magnetic resonance imaging 1 year later revealed a space-occupying lesion in the prepontine cistern along the clivus.

[Strategy for the treatment of incidental meningiomas].

The authors report a retrospective review o f 70 patients followed up for the presence of incidental, asymptomatic meningiomas. A survey was conducted of primary intracranial tumors diagnosed in Hiroshima Prefectural Hospital between 1995 and 2004. The neuroradiological imaging and clinical studies for asymptomatic meningiomas were performed during the 57.

Multiple spontaneous dissecting aneurysms of the anterior cerebral and vertebral arteries.

A 50-year-old woman presented with rare multiple dissecting aneurysms that appeared first in the anterior cerebral artery (ACA) and shortly afterwards in the vertebral artery (VA). She initially suffered sudden motor weakness in the left lower limb due to acute brain infarction. Angiography revealed diffuse string sign in the right ACA.

Cerebral venous congestion following closed head injury in a child.

In pediatric patients with head injury, progressive hemispheric low density (HLD) on CT is a specific phenomenon although the underlying mechanism remains controversial. We used CT, MRI, diffusion weighted imaging (DWI), and perfusion weighted imaging (PWI) studies to identify pathophysiological patterns in a child. A 6-year-old boy sustained a left temporal head injury in a car accident.

[Four cases of the infectious cerebral aneurysms].

The authors evaluated various clinical courses of ruptured infectious cerebral aneurysms associated with infective endocarditis in 4 patients. The first case: A 60-year-old male, who had a large hematoma resulting from rupture of a distal anterior cerebral artery aneurysm at the left frontal lobe co-existing with cerebral infarction at the right temporo-occipital lobe, with complications of renal and liver embolisms and pyogenic spondylitis, was treated with antibiotic therapy. However, he died of rupture of another newly formed aneurysm 29 days after onset.

Arteriovenous malformation of the scalp: case report and review of the literature.

Background: Arteriovenous malformations (AVMs) of the scalp are relatively rare, and their precise natural course remains to be elucidated. We encountered a patient with a scalp AVM that progressively enlarged over the course of 3 years by capturing feeders from intracranial arteries. To our knowledge, ours is the first serial angiographic depiction of the growth of a scalp AVM and the development of a de novo aneurysm in the superior temporal artery (STA) that performed as a feeder.

Reversible posterior leukoencephalopathy in a patient with Wegener granulomatosis.

A 14-year-old girl with rapidly progressive glomerulonephritis was transferred to our hospital because of acute renal failure. A diagnosis of Wegener granulomatosis was made according to the symptom triad of a renal biopsy demonstrating crescentic glomerulonephritis, severe sinusitis, and serological findings of raised proteinase 3 anti-neutrophil cytoplasmic antibody level. In spite of combination therapy with methylprednisolone, cyclophosphamide, and plasma exchange, her renal function gradually deteriorated.

[Venous thromboembolism in neurosurgery].

Clinicopathological features of venous thromboembolism (VT), such as pulmonary embolism (PE) and deep venous thrombosis (DVT), associated with intracranial diseases has not been clarified sufficiently in Japan. We investigated the clinical characteristics of VT in consecutive 3,595 group of patients retrospectively, who had been admitted to our department. The occurrence rate of VT was 0.

[Cerebellar ganglioglioma associated with a huge cyst: case report].

Gangliogliomas represent approximately 0.2% of all the intracranial tumors. Ganglioglioma arising from the cerebellum is rare, with a rate of 1.
