Schwannoma de la cadena simpática cervical asociado a adenoma paratiroideo

Abstract

Schwannoma is a rare benign tumor derived from nerve sheaths. When derived from the cervical sympathetic chain, it usually presents itself as an asymptomatic mass located in the posterior cervical region, at paravertebral level. Its diagnosis is not easy, usually requiring multiple imaging tests. Its differential diagnosis includes parathyroid adenoma.
