Nevus sebaceous is a congenital hamartomatous skin lesion that is commonly associated with other abnormalities and is most frequently located on the face and head. To our knowledge, there are no previous reports of the ultrasonographic appearance of nevus sebaceous or of an association with cystic adenomatoid malformation of the lung.
A patient was referred at 25 weeks' gestation with multiple fetal anomalies, including echogenic soft-tissue structures external to the cranium and face, a large right-side intrathoracic mass, and abdominal ascites. After a preterm delivery, nevus sebaceous and a congenital cystic adenomatoid malformation of the lung were diagnosed. Neonatal death occurred secondary to pulmonary hypoplasia.
Nevus sebaceous should be considered in the differential diagnosis when echogenic soft-tissue structures are seen on prenatal ultrasound. A detailed ultrasound examination is warranted to rule out other associated abnormalities.
皮脂腺痣是一种先天性错构瘤性皮肤病变，通常与其他异常相关，最常见于面部和头部。据我们所知，以前没有关于皮脂腺痣超声表现或与肺囊性腺样畸形关联的报道。
一名患者在妊娠25周时因多种胎儿异常前来就诊，包括颅骨和面部外部的高回声软组织结构、右侧胸腔内大肿块以及腹水。早产分娩后，诊断出皮脂腺痣和先天性肺囊性腺样畸形。新生儿因肺发育不全继发死亡。
产前超声检查发现高回声软组织结构时，鉴别诊断应考虑皮脂腺痣。有必要进行详细的超声检查以排除其他相关异常。
