Abstract
Background
A 5-month-old girl with an asymptomatic left-sided neck mass was demonstrated by ultrasound and upper gastrointestinal series (UGI), and confirmed at surgery, to have a congenital piriform fossa sinus tract (CPFST) that communicated with an intrathyroidal cyst.
Objective
To demonstrate a case of CPFST presenting as an asymptomatic neck mass. Nearly all cases of CPFST present with infection or pain, making this case unique.
Materials and methods
Case report and review of the literature.
Conclusions
CPFST with an associated cyst should be added to the differential diagnosis of asymptomatic cystic neck masses in infants, especially if the cyst is intrathyroidal by ultrasound.
