Abstracts

Two patients with cerebellopontine angle (CPA) lipoma were studied. They were submitted to surgical treatment. Available literature was reviewed and 29 cases with same lesion were identified which had been treated by surgery. Clinical manifestations, possibility of diagnostic methods, surgical indications and treatment strategies are discussed. Attention is called to the peculiarities of CPA lipomas and the doubtful vality of attempting complete excision in all cases.

RESUMO

São estudados dois pacientes com lipoma no ângulo pontocerebelar (APC), submetidos a tratamento cirúrgico. A literatura disponível foi revisada, tendo sido identificados 29 casos submetidos a tratamento cirúrgico, com a mesma lesão. As manifestações clínicas, possibilidades dos métodos diagnósticos, indicações cirúrgicas e estratégicas operatórias são discutidas. Chama-se a atenção para as peculiaridades dos lipomas do APC e a discutível validade da tentativa de remoção completa em todos os casos.

Palavras-chave: ângulo pontocerebelar, lipoma, cirurgia.
