Abstract

Oropharyngeal neuroglial choristomas are exceptionally rare head and neck tumours that contain mature neuroglial tissue. We report a case of neuroglial choristoma centred in the oropharynx and extending into the parapharyngeal space that, to the best of our knowledge, is the only case whose appearance simulated brain cortical gyri with an apparent differentiation between white and grey matter. We illustrate and detail the magnetic imaging findings of oropharyngeal choristoma that might help to establish a correct preoperative diagnosis.

摘要

口咽神经胶质迷离瘤是极为罕见的头颈部肿瘤，包含成熟的神经胶质组织。我们报告一例以口咽为中心并延伸至咽旁间隙的神经胶质迷离瘤，据我们所知，这是唯一一例其外观模拟脑皮质脑回且白质和灰质有明显分化的病例。我们展示并详细描述了口咽迷离瘤的磁共振成像表现，这可能有助于术前做出正确诊断。
