Superficial siderosis.
Case 1 An elderly patient presented with insidious onset of sensorineural hearing loss. The past history was unremarkable except for insidious onset of weakness of left lower limb. Physical examination revealed left hemiparesis with upgoing left plantar. Magnetic resonance imaging (MRI) of brain revealed a large flow void in the interpeduncular cistern suggestive of aneurysm arising from the to...
متن کاملImpaired Neurodevelopmental Outcome After Mild Germinal Matrix-Intraventricular Hemorrhage.
Germinal matrix–intraventricular hemorrhage (GMH-IVH) is a common and characteristic form of intracranial hemorrhage occurring in the premature infant. The hemorrhage originates in small blood vessels in the subependymal germinal matrix (also termed the ganglionic eminence) and may disrupt the ependymal lining and extend into the lateral ventricle. Severe IVH consists of large amounts of intrav...
متن کاملSuperficial cortical siderosis.
Cerebrovascular deposition of amyloid (cerebral amyloid angiopathy CAA) is most commonly recognized as a cause of spontaneous lobar intracerebral hemorrhage. On the basis of the noninvasive new MR imaging we would propose superficial cortical hemosiderosis and subarachnoid hemosiderosis as potentially useful new criteria to facilitate the diagnosis of CAA.
متن کاملGerminal matrix hemorrhage-intraventricular hemorrhage: pathogenesis and outcomes
Germinal matrix hemorrhage-intraventricular hemorrhage (GMH-IVH) is one of the CNS injuries affecting preterm infants occurring in about 15%–20% of subjects weighing less than 1500 g. Currently, using ultrasonography, we recognize three grades of GMH-IVH. Grade I involving the subependymal parenchyma and/or extending in less than 10% of the ventricle, grade II with intraventricular bleeding not...
متن کاملVestibular function in superficial siderosis
BACKGROUND Superficial siderosis (SS) is caused by repeated or continuous bleeding into the subarachnoid space that results in iron from hemoglobin (hemosiderin) being deposited on the surface of the brain. Clinically, the condition is characterized by sensorineural deafness, ataxia, and pyramidal signs. However the mechanism of peripheral vestibular disturbance was not revealed. We show the ve...
