We present a case of sarcoidosis in a 14-year-old girl who presented with a short history of visual disturbance. Computed tomography and magnetic resonance imaging (MRI) demonstrated enlargement of the optic chiasm and prechiasmic optic nerves. Post-contrast MRI showed marginal enhancement of the affected areas of the optic pathways. A diagnosis of optic nerve glioma and arachnoid gliomatosis was made; surgical confirmation was not sought due to the risk to vision associated with biopsy. A rapid clinical deterioration led to repeat MRI which demonstrated extensive enhancing soft tissue throughout the basal cisterns with extension into the brain. Biopsy confirmed a diagnosis of sarcoidosis.
我们报告一例14岁患有结节病的女孩，其有短暂视力障碍病史。计算机断层扫描和磁共振成像（MRI）显示视交叉和视交叉前视神经增粗。增强MRI显示视路受累区域边缘强化。诊断为视神经胶质瘤和蛛网膜胶质瘤；由于活检存在视力风险，未寻求手术确诊。临床迅速恶化促使再次进行MRI检查，结果显示整个脑基底池有广泛强化的软组织，并延伸至脑内。活检确诊为结节病。
