Congenital Hairy Polyp of the Palatopharyngeus Muscle
Figure 1
Sagittal short tau inversion recovery (STIR) (a) and sagittal T1-weighted (b) images of the nasopharynx show an oval, well-circumscribed mass (arrows) that is intimately related to the posterior aspect of the soft palate, but separate from it. The lesion is predominantly hyperintense on T1-weighted images and moderately and heterogeneously hyperintense on the T2-weighted images, features suggestive of fat content. Note the normal T1-weighted hyperintensity of the anterior pituitary (pit) in a newborn, presumably related to hypertrophy of the gland due to circulating maternal hormones.
