Dacryocystocele (mucocele, amniocele) is a relatively rare variant of nasolacrimal duct obstruction which refers to the cystic dilatation of lacrimal pathway above and below the lacrimal sac. It is a benign pathology and can be treated successfully after birth, but its prenatal detection is important, because it may be seen in numerous syndromes and may serve as their marker. Bilateral cysts have the possibility for intranasal extension and an obstruction to the nasal passages may result in neonatal respiratory distress requiring surgical intervention Unilateral cases are important for the differential diagnosis with serious facial abnormalities. We present a case of early prenatal detection of a 28 year-old G: 1 P: 0 pregnant woman with bilateral dacryocystocele. She presented a live, normally developed singleton fetus on sonographic examination at 12, 16 and 22 weeks. At 25(th) weeks, we diagnosed a hypoechogenic mass, that was situated inferomedially to the eyes in the fetal face with 2 and 3-D ultrasound. A 3850-g live female infant was delivered by Cesarean section due to breech presentation at 39 weeks following preterm rupture of membranes. We report the case with intranasal components studied during fetal life by 2 and 3-D ultrasound and magnetic resonance (MR) imaging.
泪囊膨出（黏液囊肿、羊膜囊肿）是鼻泪管阻塞的一种相对罕见的变异形式，指泪囊上下泪道的囊性扩张。它是一种良性病变，出生后可成功治疗，但其产前检测很重要，因为它可能见于多种综合征并可作为其标志物。双侧囊肿有可能向鼻内扩展，鼻道阻塞可能导致新生儿呼吸窘迫，需要手术干预。单侧病例对于与严重面部畸形的鉴别诊断很重要。我们报告一例28岁、孕1产0的孕妇双侧泪囊膨出的早期产前检测病例。在孕12周、16周和22周的超声检查中，她的胎儿存活且发育正常。在孕25周时，我们通过二维和三维超声在胎儿面部双眼内下方诊断出一个低回声团块。孕39周时，因胎膜早破臀位，经剖宫产娩出一名体重3850克的活产女婴。我们报告该病例，其鼻内成分在胎儿期通过二维和三维超声及磁共振成像进行了研究。
