ABSTRACT

OBJECTIVE:

Report our experience with trigone ventricular meningiomas and review the surgical approaches to the trigone.

METHOD:

From 1989 to 2006, six patients with meningiomas of the trigone of the lateral ventricles underwent microsurgical resection. Their clinical features, image, follow up, and surgical approaches were retrospectively analyzed.

RESULTS:

Five patients presented with large and one with small volume meningioma. Unspecific symptoms occurred in three patients; intracranial hypertension detected in three patients; homonymous hemianopsy in three; and motor deficit present in one patient. Three patients were operated by transparietal transcortical approach, two by middle temporal gyrus approach, and one by parieto-occipital interhemispheric precuneus approach. Total resection was achieved in all patients without additional deficits.

CONCLUSION:

Judicious preoperative plan, adequate knowledge of anatomy, and use of correct microsurgical techniques are fundamental in achieving complete resection of trigone meningioma with low morbidity.
RESUMO

OBJETIVO:

Relatar a experiência com seis meningiomas do trígono ventricular e discutir as várias vias de abordagem para o trígono descritos na literatura.

MÉTODO:

Seis pacientes com meningiomas do trígono ventricular operados entre 1989 e 2006 foram analisados quanto às suas características clínicas, de imagem, evolução e às vias de abordagem.

RESULTADOS:

Cinco pacientes apresentaram meningiomas de grande volume e um pequeno. Sintomas inespecíficos ocorreram em três pacientes, hipertensão intracraniana em outros três pacientes; hemianopsia homônima em três e déficit motor em um paciente. Três pacientes foram operados por via transcortical transparietal, dois através do giro temporal médio, e um por abordagem interhemisférica precuneus. A ressecção total foi possível em todos os pacientes, sem défices adicionais.

CONCLUSÃO:

Planejamento operatório cuidadoso aliado ao uso de técnicas microcirúrgicas são fundamentais na ressecção completa dos meningiomas do trígono com baixa morbidade.
