Abstract: Objective To probe the cause,clinical and imaging findings of children's congenital pyriform sinus fistula (CPSF). Methods Clinical and radiographic data in 23 patients with children’s CPSF were analyzed retrospectively which were confirmed by pathology.Results 1 6 patients represented repeated swelling and pain in left anterior neck,6 of whom were misdiagnosed as thyroid abscess and suffered surgery.7 patients represented masses in left anterior neck.Ultrasound showed all patients with diffuse en-larged thyroid gland with uneven mass and separated liquid dark space or infection in deep neck soft tissue,and no CPSF was identi-fied.The subsequent esophageal barium meal confirmed the fistula in 8 patients,and other patients underwent further CT scan with image post-processing.CT showed clear fistula in 4,suspicious fistula in 7 and no fistula in 4,All fistulas were confirmed by the pa-thology.Conclusion The combination of ultrasound,esophagogram and CT with image post-processing can improve the diagnostic sensitivity and accuracy of CPSF.
