The present report is about a 25-year-old woman who had a motorcycle accident with brain trauma injury. Although she was admitted at another institution disoriented but alert, she progressively evolved to an altered level of consciousness and required orotracheal intubation. She was then transferred to our hospital sedated, and the admission head computed tomography showed signs of posterior fossa ischemia. The angiography demonstrated a vertebral artery dissection with subsequent embolization to the basilar artery, which provoked its complete occlusion. After drug withdrawal, the patient recovered level of consciousness but was aphasic and did not exhibit purpose movements apart from eye blinking, as expected in patients with locked-in syndrome.
ResumoSarcoidose é uma doença sistêmica caracterizada por inflamação granulomatosa em que o envolvimento pulmonar e linfático é comum. Apresentamos um relato de caso raro de envolvimento do sistema nervoso central com acometimento ocular mimetizando meningioma da bainha do nervo óptico. Relatamos uma paciente de 79 anos, do sexo feminino, com diminuição visual progressiva com evolução de 4 anos. A ressonância magnética do crânio com gadolínio, através de intenso realce homogêneo pelo meio de contraste, evidenciou uma lesão expansiva no nervo óptico direito, na altura do canal óptico. A paciente foi submetida à abordagem neurocirúrgica com biópsia de lesão, que evidenciou sarcoidose do sistema nervoso central. Devido à raridade do acometimento do sistema nervoso central, o diagnóstico dessa patologia pode ser, infelizmente, postergado. O presente artigo tem como objetivo elucidar a patologia como diagnóstico diferencial dos tumores retro-orbitários. Keywords ► sarcoidosis ► ocular sarcoidosis AbstractSarcoidosis is a systemic disease characterized by granulomatous inflammation. Pulmonary and lymphatic granulomatous involvement are common. We present a rare case report of involvement of the central nervous system with ocular involvement mimicking optic nerve sheath meningioma. We report a 79-year-old female patient with progressive visual impairment with an evolution of 4 years. The magnetic resonance imaging of the cranium with gadolinium and intense homogeneous contrast enhancement revealed an expansive lesion in the right optic nerve, at the height of the optic canal. The patient was submitted to the neurosurgical approach with lesion biopsy, which showed sarcoidosis of the central nervous system. Due to the rarity of central nervous system involvement, the diagnosis of this pathology may unfortunately be postponed. This article aims to elucidate this pathology as a differential diagnosis of retro-orbital tumors.
