Paediatric parapharyngeal ganglioneuroma

A 17-year-old man initially presented to his primary care physician with throat pain for 1 week and was started on amoxicillin. After four additional days of ongoing pain and difficulty swallowing with decreased oral intake, he presented to the emergency department. Exam showed fullness to the right posterior oropharynx and palpable mass in the right neck without stridor. Initial imaging was soft tissue neck CT with contrast, which showed cystic 8 cm mass in the parapharyngeal space. Patient additionally underwent MRI, which showed an 8.6 cm mass in the right posterior oropharynx with obliteration of the vallecula. Differential diagnosis included abscess; therefore, ear, nose, and throat (ENT) specialist was consulted for possible drainage. Intraoperatively, there was no abscess; alternatively a biopsy was obtained, which was identified by pathology as a ganglioneuroma. Patient was referred to paediatric ENT specialist, underwent extensive resection confirming diagnosis of ganglioneuroma and did well postoperatively.
