Background. Teratomas are the most common tumors. They are usually localized in the sacrococcygeal area, while the pharyngeal localization is very rare. The number of cases of stomatopharyngeal teratomas detected prenatally via sonography is very small. Case Report. We present the case of a 24-year-old primipara at 18 weeks' gestation, that at the routine ultrasound scan, the fetus was found with an echogenic mass, filling the stomatopharyngeal cavity and protruding from the mouth. Other abnormalities were not found. Termination of pregnancy was achieved using misoprostol. A female stillborn fetus with a weight of 250 g and length of 25.5 cm was delivered. The postmortem and pathologic examination confirmed the diagnosis. Conclusion. Pharyngeal teratomas can be diagnosed with the use of ultrasounds in utero facilitating parents' counseling in early time.
背景。畸胎瘤是最常见的肿瘤。它们通常位于骶尾部区域，而咽部定位非常罕见。产前通过超声检查发现的口咽畸胎瘤病例数量非常少。病例报告。我们报告一例24岁初产妇，妊娠18周，在常规超声检查时，发现胎儿有一个回声团块，充满口咽腔并从口腔突出。未发现其他异常。使用米索前列醇终止妊娠。分娩出一名体重250克、身长25.5厘米的女死胎。尸检和病理检查确诊。结论。子宫内超声检查可诊断咽部畸胎瘤，有助于早期为父母提供咨询。
