OBJECT Direct delivery of chemotherapeutic agents for the treatment of brain tumors is an area of focus in the development of therapeutic paradigms because this method of delivery circumvents the blood-brain barrier without causing adverse systemic side effects. Few studies have investigated longitudinal tumor response to this type of therapy. In this(More)
PURPOSE Currently, there is no conclusive treatment for brainstem tumor. To facilitate the development of new treatments, it is essential to establish predictive preclinical in vivo models in which therapeutic modalities can be evaluated. Although a few rodent models have been reported, there is no novel approach that can monitor tumor response(More)
PURPOSE Local direct delivery of chemotherapeutic agents for the treatment of brain tumors is an area of focus in the development of new therapeutic paradigms. These techniques need improvement, especially in terms of drug retention in brain tissue. MATERIALS AND METHODS In this study, we used a rat glioma model to examine carboplatin distribution, as(More)
A 75-year-old male suffered sudden onset of retroorbital pain, visual loss, periorbital ecchymosis, and double vision without preceding trauma, paranasal sinus surgery, or infectious signs. Neuroophthalmological inspection also revealed marked restriction of the extraocular movements, visual defect, and exophthalmos on the affected side. Neuroimaging showed(More)
A 58-year-old male, with a past history of hypertensive thalamic hemorrhage 12 years before, presented with gradually exaggerating gait disturbance, memory disturbance, and urinary incontinence. On admission, he had gait disturbance represented by petit pas and anteropulsion in addition to significant recent memory disturbance. Cranial computed tomography(More)
Prenatal ultrasonography of a 17-year-old pregnant female detected ventriculomegaly of the fetus at 31 weeks of gestation. Her medical and family histories were unremarkable. Fetal magnetic resonance imaging taken at 33 weeks of gestation showed a tumorous lesion with ventriculomegaly. A male baby was delivered by cesarean section at 36 weeks of gestation.(More)
A 36-year-old man with no history of immunosuppression presented with diabetes insipidus, but no other hormonal disturbances. Magnetic resonance imaging of the brain revealed an enhanced mass in the pituitary stalk appearing as a thickened pituitary stalk. The mass lesion was completely removed through the right optico-carotid space. Histological(More)
INTRODUCTION Myelomeningocele is one of the major congenital malformations involving the central nervous system. It is caused by a disruption of the neural tube closure, which is completed at 3-4 weeks of gestation. DISCUSSION Multidisciplinary approach is necessary to treat and support this malformation which is a huge burden to the patient, family, and(More)
We present detailed ophthalmic findings in a case of tuberculum sellae meningioma with acute visual symptoms due to optic canal involvement. A 62-year-old Japanese woman reported a 1-week history of headaches and blurred vision in her left eye. Her visual acuity was 0.3 in the left eye with no ophthalmoscopic abnormalities. A relative afferent pupillary(More)
BACKGROUND It is extremely rare to see cerebrospinal fluid dissemination of intraventricular meningioma, particularly with the development of acute, progressive brainstem/cerebellar dysfunction with an absence of mass formation in the corresponding anatomical sites. CASE PRESENTATION An 81-year-old man was admitted because of double vision, right facial(More)
