PURPOSE: In neonates, pyriform sinus fistulas and lymphangiomas require different early treatment, such as surgical resection or sclerosing therapy, respectively. We aimed to evaluate the use of sonographic findings for differentiating between pyriform sinus fistulas and lymphangiomas in neonates with a lateral cervical cystic mass.
METHODS: Sixteen cases diagnosed with pyriform sinus fistulas (n = 7) or lymphangiomas (n = 9) were included. Sonographic findings, including fistulas from the pyriform sinus, air-containing cysts, abnormal thyroid parenchyma echogenicity, internal septae within the cyst and spread to the opposite cervical site, were compared between neonates with pyriform sinus fistulas and those with lymphangiomas. Fisher's exact was used for statistical comparisons.
RESULTS: A significant difference was observed between cases with and without air-containing cysts (present/absent in neonate with pyriform sinus fistula vs lymphangioma: 5/2 vs. 0/9; p = 0.005), abnormal thyroid parenchyma echogenicity (present/absent: 4/3 vs. 0/9; p = 0.019), and internal septae within the cysts (present/absent: 2/7 vs. 9/9; p = 0.005). No significant differences were observed between cases with or without a fistula from the pyriform sinus (present/absent: 2/5 vs. 9/0; p = 0.175) and spread to the opposite cervical site (present/absent: 4/3 vs. 4/5; p = 0.500).
CONCLUSIONS: Ultrasound can differentiate pyriform sinus fistulas from lymphangiomas in neonates. In our small cohort, if they exhibited the respective sonographic findings; fistula from pyriform sinus, air-containing cysts or abnormal thyroid parenchyma echogenicity, patients were diagnosed as cases of pyriform sinus fistula. These diagnoses are critical for pediatric surgeons or otolaryngologists in surgical planning.
