Parapharyngeal space (PPS) tumors are extremely rare in the pediatric population, accounting for a small fraction of all head and neck neoplasms. The majority of neoplasms in the PPS are benign tumors. We present a case of an eight-year-old male with a large PPS ganglioneuroma, who presented with a neck mass that had been progressing over five years with no symptoms of dysphasia. Diagnostic imaging, including computed tomography scan and magnetic resonance imaging with contrast, revealed a large, heterogeneously enhancing mass, measuring about 4.47 × 6.49 × 2.56 cm in size, in the right poststyloid PPS. The tumor extended closely from the common carotid artery bifurcation to the skull base, without intracranial extension. A transcervical surgical approach enabled complete tumor excision without complications. Postoperative histopathology confirmed the diagnosis of ganglioneuroma, a very rare case in pediatric PPS tumors. No postoperative complications were noted, and follow-up over two years revealed no signs of recurrence.
咽旁间隙（PPS）肿瘤在儿科人群中极为罕见，仅占所有头颈部肿瘤的一小部分。PPS中的大多数肿瘤为良性肿瘤。我们报告一例8岁男性患有巨大PPS神经节细胞瘤，该患者颈部肿块已持续进展5年，无吞咽困难症状。诊断性影像学检查，包括计算机断层扫描和增强磁共振成像，显示右侧茎突后PPS有一个巨大的、不均匀强化的肿块，大小约为4.47×6.49×2.56 cm。肿瘤从颈总动脉分叉处紧密延伸至颅底，无颅内延伸。经颈手术入路实现了肿瘤的完整切除且无并发症。术后组织病理学确诊为神经节细胞瘤，这在儿科PPS肿瘤中是非常罕见的病例。未观察到术后并发症，两年的随访未发现复发迹象。
