Background
Hairy polyps are the most common congenital deformity of the oral-nasopharynx/oral cavity in infants, which may lead to severe complications in the newborns. However, few studies have been published with respect to their radiological features, and most are case reports.
Objective
This study aimed to analyze radiological features of the oral‑nasopharyngeal hairy polyps and to identify the radiological features with the highest diagnostic value.
Materials and methods
From 2014 to 2019, pediatric cases pathologically diagnosed as hairy polyps and having received radiological examination at the Children’s Hospital Affiliated to Zhejiang University were retrospectively analyzed. Radiological evaluations were conducted on tumor size, location, morphology, density or signal features as well as the enhancement pattern.
Results
A total of six infants were recruited. Clinical features observed in these cases included choking on milk with cyanosis, intermittent dyspnea, oropharyngeal mass, and snoring. Lesions were derived from the left tubal torus in three out of six cases, from the left lateral aspect of soft palate in one, from the left lateral pharyngeal wall in one, and from the right tubal torus in one. They were shown as pedicled polyp-like well-circumscribed mass with fat density or signal as well as a stalk on CT or MRI. In the contrast-enhanced scan, the fat components were not enhanced, while the stalk was mildly enhanced.
Conclusion
Hairy polyps had typical radiological features. Hairy polyps should be considered for pedicled polyp-like well-circumscribed mass in the oral-nasopharynx of infants with fat density or signal as well as a stalk.
