Abstract

Schwannomas of peripheral nerves are the most common benign tumors in this location; it has specific radiologic and histologic features that enable its fundamental distinction of neurofibromas. Given its importance in neurosurgical practice, known radiologic and histologic criteria must be updated regarding this disease entity, as well as its therapeutic strategy and results obtained with it. This article reviews this subject, followed by a case report considered out of the ordinary, in which the tumor was located in the sciatic nerve in a patient with neurofibromatosis type 1, treated by microsurgical resection, which evolved favorably.

Resumo

Os schwannomas dos nervos periféricos são os tumores benignos mais comuns nesta localização. Apresentam características radiológicas e histológicas específicas que possibilitam a sua fundamental distinção dos neurofibromas. Dada a sua importância na prática neurocirúrgica, devem ser conhecidos os critérios radiológicos e histológicos atualizados à respeito desta entidade nosológica, bem como sua estratégia terapêutica e o resultado com ela obtido. Neste artigo, é feita uma revisão do tema, seguido do relato de um caso considerado fora do habitual, no qual o tumor localizava-se no nervo ciático, em uma paciente portadora de neurofibromatose tipo 1, tratada por meio de ressecção microcirúrgica, que evoluiu de forma favorável.
