Superficial cortical siderosis.

چکیده
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.

Diagnostic Significance of Cortical Superficial Siderosis for Alzheimer Disease in Patients with Cognitive Impairment.
BACKGROUND AND PURPOSE Because the diagnostic significance of cortical superficial siderosis for Alzheimer disease and the association between cortical superficial siderosis and the topographic distribution of cerebral microbleeds have been unclear, we investigated the association between cortical superficial siderosis and clinicoradiologic characteristics of patients with cognitive impairment....
متن کاملSuperficial siderosis: a potential diagnostic marker of cerebral amyloid angiopathy in Alzheimer disease.
BACKGROUND AND PURPOSE Superficial siderosis of the central nervous system results from chronic bleeding in the superficial layers of the cortex and spinal cord. In cerebral amyloid angiopathy (CAA), there is amyloid deposition in meningeal and meningo-cortical arteries and capillaries, predisposing them to rupture. CAA is frequently associated with Alzheimer disease (AD). METHODS We report a...
متن کاملA patient with superficial siderosis, intraspinal cyst, low-pressure headache and low-lying cord.
Superficial siderosis is a rare condition caused by deposition of hemosiderin in the central nervous system. In recent years, it has been used to identify dural defects connecting the intrathecal space with the intraspinal fluid-filled collection seen in patients with superficial siderosis. However rare reports describe the association of low-lying cord in superficial siderosis patients. We pre...
متن کاملSuperficial siderosis of the central nervous system.
We report five cases of superficial siderosis of the central nervous system. All patients developed progressive deafness and cerebellar ataxia associated with pyramidal tract signs or mental deterioration. The cerebrospinal fluid examinations usually revealed an elevated protein level, without other abnormalities. Magnetic resonance imaging typically showed a hypointense rim around the cerebral...

Superficial Siderosis (SS) is a rare neurological condition which results from hemosiderin deposition on the leptomeninges, subpial and ependymal surfaces of the central nervous system (CNS). Patients commonly present with the classic triad of hearing loss, cerebellar ataxia and pyramidal signs. We report clinical, radiological and pathological findings in a patient with SS due to chronic haemo...
