梨状窝瘘(PSF)是一种起源于咽袋的先天性畸形。PSF最初被认为是胎儿颈部的囊肿，但对这种疾病的准确产前诊断是具有挑战性的。我们的目标是报告准确地将PSF与其他鉴别诊断相区别的关键发现和技巧，从而能够检测到颈部囊肿和咽部的交通。以会厌为标志，发现咽部单叶囊肿1例。结论超声检查是PSF产前诊断的有力工具，尤其是在妊娠早期。通过对会厌的检测，可以定位颈部囊肿与咽部的交通，从而对PSF做出准确的诊断。
ObjectivePyriform sinus fistula (PSF) is a congenital anomaly which originates from the pharyngeal pouch. PSF is initially recognized as a cyst around the fetal neck, but accurate prenatal diagnosis of the disease is challenging. We aimed to report the key findings and tips in accurately distinguishing PSF from other differential diagnosis by which enables detection of the communication of the nuchal cyst and the pharynx.Case reportWe report a case in which we were able to diagnose PSF as early as 18 weeks of gestation with ultrasonography. We used epiglottis as a landmark, and detected an unilobular cyst arising from the pharynx.ConclusionUltrasonography is a powerful tool in prenatal diagnosis of PSF especially at early stage of pregnancy. By detecting the epiglottis, it can locate the communication of the nuchal cyst and the pharynx, and thereby enables an accurate diagnosis of PSF.
