Parapharyngeal neuroglial heterotopia appearing as high uptake on 18 F–FDG PET: case report and literature review of radiographical findings

Abstract

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 (¹H–MRS) and ¹⁸F–fluorodesoxyglucose positron emission tomography (¹⁸F–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. ¹H–MRS showed a non-malignant pattern, but ¹⁸F–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.
