Parapharyngeal neuroglial heterotopia is a rare entity, and the specific radiographical findings are unclear. We present a case of parapharyngeal neuroglial heterotopia examined with proton magnetic resonance spectroscopy (H-MRS) and F-fluorodesoxyglucose positron emission tomography (F-FDG PET). Our neonate patient presented with neck mass and polyhydramnios during gestation. Computed tomography and magnetic resonance imaging demonstrated the morphological characteristics, but failed to establish the diagnosis. H-MRS showed a non-malignant pattern, but F-FDG PET demonstrated high glucose metabolism. Complete resection was achieved and the histopathological diagnosis was neuroglial heterotopia. Assessment of biological activity may be useful for both preoperative diagnosis and postoperative evaluation of residual lesions.
咽旁神经胶质异位是一种罕见的病症，其具体的影像学表现尚不清楚。我们报告一例经质子磁共振波谱（H-MRS）和F-氟脱氧葡萄糖正电子发射断层扫描（F-FDG PET）检查的咽旁神经胶质异位病例。我们的新生儿患者在孕期出现颈部肿块和羊水过多。计算机断层扫描和磁共振成像显示了形态特征，但未能确诊。H-MRS显示为非恶性模式，但F-FDG PET显示高糖代谢。手术完整切除，组织病理学诊断为神经胶质异位。评估生物学活性可能对术前诊断和术后残余病变评估均有用。
