Prenatally detected abdominal and pelvic masses are commonly cystic in morphology and usually seen on mid-trimester sonography. Sonography is the favored imaging modality for the postnatal evaluation of these lesions in newborns, given its availability, low cost, lack of ionizing radiation, lack of sedation, and high spatial resolution in small patients. The differential diagnosis of abdominopelvic cystic masses in newborns is broad given that they can arise from many organs and may have overlapping features on imaging. This article illustrates an approach to the postnatal sonographic evaluation of prenatally detected cystic abdominal and pelvic masses based on their anatomic location and distinctive sonographic characteristics, which can aid in an accurate diagnosis and guide appropriate management.
产前检测到的腹部和盆腔肿块在形态上通常为囊性，且常在孕中期超声检查时发现。超声检查因其可及性、低成本、无电离辐射、无需镇静以及对小儿患者的高空间分辨率，成为新生儿这些病变产后评估中首选的成像方式。鉴于新生儿腹盆腔囊性肿块可起源于多个器官且在影像学上可能有重叠特征，其鉴别诊断范围很广。本文阐述了一种基于产前检测到的囊性腹部和盆腔肿块的解剖位置及独特超声特征进行产后超声评估的方法，这有助于准确诊断并指导恰当的处理。
