“…Previously described variations within the posterior cord include differences in the nerve composition of the posterior cord, such as only receiving contributions from the middle and inferior trunks with no superior trunk, or being formed by the superior and middle trunks alone with no inferior trunk [ 22 , 23 ]. An accessory branch of the posterior cord was noted in a case report by Banik et al (2022), in which an additional branch arose from the posterior cord and supplied the triceps muscle [ 24 ]. Another notable anomaly is the split posterior cord, in which the posterior cord was formed normally by the superior, middle, and inferior trunks, but splits to give off 2 separate branches, one giving off the axillary nerve and another gave off the radial nerve [ 3 ].…”

“…While posterior cord anomalies are common, awareness of these anomalies is important to avoid injury to variant posterior cords and terminal branches during neck and axillary dissection [ 24 ]. The spread of anesthesia is also impacted with cord variations, which may cause undesirable nerve blockades and the inability to predict the dissemination of local anesthetics [ 22 , 25 ].…”

“…Para além disso, é muito importante enfatizar que, na prática clínica, é frequentemente desafiador distinguir entre Schwannomas do plexo braquial e linfonodos patológicos, pois estes últimos, seja como metástase ou linfoma, também podem exibir características intrínsecas como perda do hilo gorduroso normal, hipoecogenicidade e tendência à multiplicidade, bilateralidade e alterações nodais ou perinodais. Tais aspectos podem servir como pontos de referência radiológica para o diagnóstico diferencial (BANIK, et al, 2021).…”

“…Ademais Banik et al (2021), ao submeter amostras de tumores benignos ao exame anatomopatológico, evidenciou a presença de células tumorais que estavam dispostas em fascículos curtos, tendo um núcleo vesicular alongado e citoplasma fibrilar moderado. Nenhuma atividade mitótica foi observada.…”
