An infant boy known to have a secondary cleft palate presented with apneic episodes and sternal retractions. He had been delivered vaginally at term, with the pregnancy complicated by preeclampsia and oligohydraminos.
On examination there was a 3-cm, smooth, whitish tan mass emanating from the right lateral pharyngeal wall (Figure, A) and protruding down through the secondary cleft palate. A contrast-enhanced maxillofacial computed tomographic (CT) scan was obtained. This revealed a well-defined, round heterogeneous, midline mass obstructing the oropharynx and posterior nasopharynx (Figure, B-D). The mass had a mildly enhancing thick wall with a central focus of decreased enhancement, with attenuation similar to fluid. No discrete foci of calcification or fat were identified.
