Bilateral cystic pulmonary glial heterotopia and palatinal teratoma causing respiratory distress in an infant

We report on a male infant with extensive, bilateral cystic and solid lung lesions who presented postnatally with respiratory distress caused by bilateral cystic lung lesions.Parenchyma-sparing resections were performed. Histology revealed the presence of neuroglial cell-lined cysts and glial nodules. In addition, a neural element containing palatinal teratoma was detected and excised. Based on previously published cases, the pathogenesis and clinical features of pulmonary neuroglial heterotopia are discussed.
