Complete laryngotracheoesophageal cleft: CT diagnosis and associated abnormalities.

A case of complete laryngotracheoesophageal cleft is described in a male infant in which bronchoscopy could not be performed due to a narrow tracheal orifice. CT scan of the thorax demonstrated a common tracheal and oesophageal lumen extending inferiorly to the carina, with hypoplasia of the right lung and cardiac dextroposition. Contrast studies demonstrated a hypoplastic intrathoracic stomach. Chromosome analysis revealed satellites on the Y chromosome with karyotype 46XYqs.
