Ganglioneuroblastoma is usually located in the adrenal gland, retroperitoneal ganglia, or posterior mediastinum, but rarely occurs in the parapharyngeal space.
A 4-year-old girl presented with complaint of progressive inspiratory dyspnea and dysphagia, accompanying left-side Horner's syndrome.
Computed tomography (CT) scan revealed a giant mass with irregular low density in left oropharyngeal and posterior pharyngeal wall. The left carotid artery sheath was pushed to the right. After enhancement, the central part of the mass was strengthened, and the surrounding bones structures appeard normal. Magnetic resonance imaging (MRI) showed a solid mass in the left parapharyngeal space displacing the left carotid sheath posteriorly and laterally. A ganglioneuroblastoma was diagnosed.
The girl was treated by surgery.
The postoperative course was uneventful. There was no recurrence was observed during the 1-year follow-up.
The primary cervical ganglioneuroblastoma is rare, we recommended the ganglioneuroblastoma should be considered in the differential diagnosis of a child presenting with a parapharyngeal space mass.
神经节神经母细胞瘤通常位于肾上腺、腹膜后神经节或后纵隔，但很少发生于咽旁间隙。
一名4岁女孩因进行性吸气性呼吸困难和吞咽困难就诊，并伴有左侧霍纳综合征。
计算机断层扫描（CT）显示左侧口咽和咽后壁有一个巨大的不规则低密度肿块。左侧颈动脉鞘被推向右方。增强后，肿块中央部分强化，周围骨骼结构正常。磁共振成像（MRI）显示左侧咽旁间隙有一个实性肿块，将左侧颈动脉鞘向后外侧推移。诊断为神经节神经母细胞瘤。
该女孩接受了手术治疗。
术后过程顺利。在1年的随访中未观察到复发。
原发性颈部神经节神经母细胞瘤罕见，对于出现咽旁间隙肿块的儿童，我们建议在鉴别诊断中考虑神经节神经母细胞瘤。
