“…Secondly, the size of AVM may be such as to exert pressure upon certain parts of the brain (mass eff ect). Finally, a large volume of blood shunted through the AVM may result in so-called 'steal phenomenon' that leads to temporary or permanent ischemia of neuronal structures 17,18,32 . Th e concept of 'steal phenomenon' has been recently challenged 29 .…”

“…In two patients, the presence of AVM was detected just after its rupture and subsequent subarachnoid hemorrhage. Selective embolization was performed in one patient with tremor, but without clinical improvement 17 . Krauss et al report on six patients, of which one had hemidystonia caused by AVM in the contralateral frontoparietal lobe.…”

SUMMARY -Chorea is a movement disorder that can be caused by a large range of degenerative, vascular, metabolic and toxic disorders in basal ganglia. Arteriovenous malformations are rare vascular malformations the clinical presentation of which depends on the malformation characteristics and localization. Th ey are most commonly presented with intracranial hemorrhage, while focal neurological defi cit is the rarest presentation. A case is reported of a 64-year-old female patient presented with hemichorea. Magnetic resonance imaging and digital subtraction angiography revealed the presence of arteriovenous malformation in the right temporal lobe.

“…A distonia e outros distúrbios do movimento associadas à MAV, apesar de raros, têm sido descritos. Lobo-Antunes et al 7 descreveram quatro pacientes com distonia associada à MAV, tendo as seguintes distribuições: braço (1 caso), pescoço (2 casos) e mão esquerda (1 caso). Shaw et al 8 citaram um paciente com acometimento do pescoço.…”

Rodrigues 4RESUMO -A distonia é uma síndrome neurológica cuja etiologia costuma não ser bem definida. Relatamos caso de uma paciente que apresentou aos 16 anos de idade dificuldade para tocar piano, havendo um comprometimento progressivo da mão, antebraço e braço esquerdo que posteriormente evoluiu com crises de ausência e cefaléia. Realizou exames de imagem que evidenciaram angioma cavernoso na região temporal profunda direita (ínsula). É rara a associação entre essas duas enfermidades, não havendo na literatura relato de distonia segmentar associada a crises de pseudoausência e cefaléia com características migranosas secundária ao angioma cavernoso. Vinte e cinco por cento das distonias são secundárias, o que nos faz sugerir uma investigação mínima em neuroimagem.PALAVRAS-CHAVE: distonia segmentar, angioma cavernoso, mal formação arteriovenosa.Segmental dystonia as manifestation of cavernous angioma: case report ABSTRACT -Dystonia is a neurologic syndrome whose ethiology is not well recognized. We report a sixteen year old patient with difficulty in playing piano, with disability of the left hand, forearm and arm. Short after, she underwent absence crises and headache. Neuroradiological exams showed a deep temporal lobe cavernous angioma. It is a rare association between both diseases and there are no reports about segmental dystonia associated to pseudoabsence epilepsy and sporadic migrane secondary to cavernous angioma. Twenty five per cent of dystonias have a secondary cause and we suggest a neuroradiologic investigation. A distonia é uma síndrome neurológica caracterizada por contrações involuntárias, sustentadas, padronizadas e em sua maioria, repetitivas, com antagonismo muscular causando torção, movimentos esporádicos ou posturas anormais. Pode ser classificada de acordo com a intensidade, características clínicas, distribuição, idade de início e etiologia. Quanto à classificação por distribuição, existem as distonias focal, segmentar, multifocal, generalizada e hemidistonia. Em setenta e cinco por cento dos casos não possui um substrato anatomopatológico e etiológico bem definidos. Por conta disso, é considerada muitas vezes como manifestação primária do sistema nervoso central. Inúmeras causas têm sido atribuídas às distonias, entre elas: lesão perinatal, lesões cerebrais focais (tumor, vascular, infecciosa), processos neurodegenerativos, distúrbios metabóli-cos, drogas e outros agentes químicos 1-2 . Considerando-se as causas vasculares, existem poucos trabalhos sobre a mal-formação arteriovenosa e os distúrbios do movimento. Não há relato na literatura da associação entre distonia segmentar e angioma cavernoso como aqui descrevemos. CASOPaciente feminina, 27 anos, negra, natural do Estado do Rio de Janeiro, professora.

“…In a recent review of 1,000 cases reported by vari ous workers, Lobo-Antones et al (1974) cite only 6 cases in whom such movements were present. In 1 patient with an unspecified deepseated malformation (Patterson and McKissock, 1956) they were hemilateral athetoid move ments; in the case of Shaw et al (1972), a malformation supplied by the middle cerebral artery gave rise to spastic torticollis; the other 4 cases were observed and carefully studied by Lobo- Antones et al (1974). The first, with a malformation fed by the anterior choroid ar tery and by the perforating branches of the posterior communicating artery and posterior cerebral artery, presented athetoid-type move ments of the contralateral upper limb followed some time later by tremor and dystonia.…”

“…2 of the 4 cases (first and second) observed by Lobo-Antones et al (1974) had acute hem orrhages, which called for angiographic study. In all cases except the third, the hyperkinesias were accompanied by other neurological signs (pyramidal signs, paralysis of the oculomotor or other cranial nerves, disturbed coordination of movement) which worsened after the acute episodes.…”

Intention and Action Myoclonus from Thalamic Angioma

Clinical electrophysiological and neuroradiological examination of a case of unilateral intention and action myoclonus is reported. Brachial arteriography revealed an angioma located mainly in the lateral portion of the right posterior thalamus. Clinical and electrophysiological findings suggesting involvement of nonthalamic structures were absent. Our case, together with some cases previously described, raises the possibility that volitional myoclonus may be related to a relatively circumscribed damage of some diencephalic and/or mesencephalic structures. The rare occurrence of a hyperkinetic syndrome as principal symptom of a cerebral vascular malformation should be borne in mind in view of the potential risk of a stereotactic surgical procedure designated to alleviate the involuntary movements.
