Neuropathology of cerebral arteriovenous malformations in children.
نویسندگان
چکیده
Neuropathological findings in children who had died of cerebral arteriovenous malformation under 6 years of age were contrasted with those of children aged 6 to 15 years. In all subjects, the abnormalities were more marked in the shunting vessels and veins distal to the arteriovenous shunt than in the arteries. Fibrous thickening, calcification an adherent thrombus of vessel wall, and gliosis and haemosiderin in contiguous neural tissue were more common in the older than the younger children. Children less than 1 week old with vein of Galen malformations presented with congestive heart failure and "watershed" cerebral infarction; most of those over one week old had hydrocephalus and venous thrombosis with haemorrhagic infarction.

متن کاملMolecular neuropathology of epilepsy-associated glioneuronal malformations.
Glioneuronal malformations (malformations of cortical development [MCD]) include focal cortical dysplasias (FCD) as well as highly differentiated glioneuronal tumors (i.e. gangliogliomas) and constitute frequent findings in patients with pharmacoresistent focal epilepsies. Tailored resection strategies evolved as promising treatment options and allow a systematic neuropathologic and molecular b...
متن کاملDiffuse Pulmonary Arteriovenous Malformation in Children: Essential Value of Contrast Echocardiography in Diagnosis
Pulmonary arteriovenous malformations (PAVM) are abnormal communications between pulmonary arteries and pulmonary veins, and most commonly congenital in nature. Although rare, it is an important consideration in cyanotic patients of unknown cause. We report 3 cases with diffuse PAVM in children with different clinical manifestations and initial diagnosis was made by transthoracic contrast echoc...
متن کاملRecurrent cerebral arteriovenous malformation in a child : case report and review of the literature.
Arteriovenous malformations (AVM) are generally considered to be cured following angiographically proven complete resection. However, rare instances of AVM recurrence have been reported in both children and adults with negative findings on postoperative angiography. The authors present the case of a 12-year-old boy with recurrent AVM. The AVM was originally fed by the pericallosal arteries on b...
