Heterotopic neuroglial tissue causing upper airway obstruction in a newborn.

Heterotopic neuroglial tissue, composed of differentiated neuroectodermal tissue, represents developmental heterotopia of neuroglial tissue rather than true neoplasm. Herein, we present a patient with nasopharyngeal heterotopic neuroglial tissue who presented with respiratory distress and feeding difficulty in early days after birth. Magnetic resonance imaging showed a cystic lesion measuring about 3 x 1.5 cm in the nasopharynx near the uvula. The lesion was resected and confirmed histologically as a heterotopic neuroglial tissue.
