Abstract:
This article reported a case of fetal congenital pyriform sinus fistula (CPSF) diagnosed by prenatal ultrasound. An oval cystic mass in the left side of the fetal neck was detected during routine prenatal ultrasonography at 17 +2 weeks of gestation, which was also found in the systemic ultrasound screening at 23 weeks. Besides, a narrow fistula between the cyst and pharynx was observed in the coronal view of the neck, raising the suspicion of CPSF. On day 21 after birth, the cystic mass bulged out of the neck and the neonate started choking and coughing during feeding alongside wheezing respiration. Ultrasound examination showed a strong gas echo in the cystic mass, which was also confirmed by CT scan on day 25. On day 26, cystectomy, ligation of high fistula, and fistulectomy were performed, and the diagnosis of CPSF was confirmed. The baby recovered after the operation and was healthy during follow-up till three months.
