ABSTRACT
Schwannomas are tumors originating from Schwann cells, about 45% of them are located in the head and neck region, including the parapharyngeal space (PFS). Vagus nerve schwannomas (VS) and cervical sympathetic chain schwannomas (CSCS) are most commonly found in this region. We present a case of CSCS located in the PFS of a middle-aged female patient who had surgery with the endoscopic endonasal approach (EEA). There have been no earlier reports of CSCS resection utilizing EEA, according to our literature search. To our knowledge, there is no scientific record of CSCS resection using EEA.
ABSTRACT
Somente 1% de todas as cirurgias hipofisárias são realizadas para tratar tumores metastáticos desta região. Os focos primários mais comuns são respectivamente mama e pulmão. Neste artigo, descrevemos uma paciente com antecedente de adenocarcinoma mamário, que se apresenta com paralisia oculomotora súbita à direita. O objetivo do trabalho é descrever um caso de metástase mamária para a região selar, evidenciando dados clínicos e radiológicos que tornam tal diagnóstico plausível.
Only 1% of all pituitary surgeries are performed to treat metastatic tumors in this region. The most common primary sites are breast and lung respectively. In this article we describe a patient with previous breast adenocarcinoma presenting with oculomotor palsy sudden right. The objective is to describe a case of breast metastasis to the sellar region, showing clinical and radiological findings that make this plausible diagnosis.
