title: Suspicion of prenatal pyriform sinus cyst and fistula: a case report.
abstract: There has been no report describing suspected prenatal pyriform sinus (PS) cyst and fistula. We report a case suspected by prenatal ultrasonography and fetal MRI. A large cystic mass was found in the left neck of the fetus. After the baby was born, preoperative laryngoscopic catheterization of the fistula tract was used to confirm the diagnosis and greatly facilitated the identification and excision of the PS cyst and fistula.
