Heterotopic central Nervous tissue - nasal glioma : A case report

An unusual presentation of neuroglial heterotopia: case report

We report a rare case of nasopharyngeal neuroglial heterotopia in a 16-year-old girl who presented with sore throat and feeling of a lump in her throat. Neuroglial heterotopia is a mass composed of misplaced neural tissue during embryonic development which has lost its intracranial connection. A careful review of literature in PUBMED shows most of the previously reported cases of nasopharyngeal glial heterotopia presented during neonatal or infancy period with symptoms of respiratory distress or airway obstruction. Our case caused a diagnostic dilemma due to late presentation and atypical radiological findings. Imaging, especially MRI, is vital for evaluating such nasopharyngeal masses in children for pre-surgical planning and more importantly to rule out any intracranial communication. Treatment is surgical resection by endoscopic or external approach, with a rare possibility of recurrence.
