Análise retrospectiva de 20 pacientes acometidos por schwannoma nos membros superior e inferior

Abstract: Resumo Objetivo Analisar o perfil epidemiológico e a evolução de 20 pacientes diagnosticados com schwannoma nos membros superiores e inferiores. Métodos Definiu-se um grupo de pacientes para avaliação retrospectiva, compreendendo o período entre fevereiro de 2002 e junho de 2018, no qual foram estudados e avaliados 20 prontuários de pacientes submetidos a procedimento cirúrgico devido a schwannoma; a confirmação diagnóstica foi feita pelo exame anatomopatológico. Resultados Tanto … Show more

“…Furthermore, in cases when a schwannoma affects the upper limbs, it has been reported to prefer the anterior surface of the forearm due to the high concentration of nerve fibers, of which the ulnar and median nerves are the most affected. 3 In the case of this patient, radiography was requested for differential diagnosis, and electroneuromyography for confirmation. As there was no palpable mass, imaging tests such as ultrasound (US) or magnetic resonance imaging (MRI) were not requested, since the motor alteration was already triggered.…”

“…As there was no palpable mass, imaging tests such as ultrasound (US) or magnetic resonance imaging (MRI) were not requested, since the motor alteration was already triggered. However, some authors, such as Galbiatti et al 3 and Wheeler and DeCastro 4 believe that, although the clinical examination is paramount, an image exam such as US or MRI should be requested for differential diagnosis of soft tissues.…”

“…Recurrence is extremely rare (less than 1%) unless tumor tissue is removed improperly. 5,8,9 Given that the symptoms in this type of lesion are often mild or may not even exist, the delay in diagnosis is frequent in cases of lower limb schwannoma, and there are even reports of cases where it took approximately 15 years to get the proper diagnosis. Therefore, rigorous clinical examination, associated with MRI scans and histological evaluation, allow for adequate diagnosis and the exclusion of other pathologies with similar clinical presentation.…”
