“Double eyes” sign of congenital bilateral dacryocystoceles

Abstract

Dacryocystocele is caused by nasolacrimal duct obstruction and results in cystic dilatation of the proximal part of the nasolacrimal duct, which is located inferomedial to the orbit, leading to fluid accumulation. It is important to consider that persistent congenital bilateral dacryocystoceles may cause neonatal nasal obstruction resulting in respiratory difficulty, and large dacryocystoceles may require surgical drainage. Ultrasonography demonstrates that congenital bilateral dacryocystoceles and normal eyeballs prenatally resemble two pairs of cystic "lesions" of different sizes. We herein present a case of prenatally diagnosed isolated congenital bilateral dacryocystoceles and propose the new name of "double eyes" sign for this rare condition to create an impact on medical students and residents.

Is congenital dacryocystocele a benign, self‐limited disorder? A review of the literature with four new cases

“…Out of the 125 unilateral cases, 70 were right-sided, whereas 55 were leftsided. Seven of the studies reported 21 nonisolated cases including 15 major abnormalities such as central nervous system (CNS) anomalies, cardiac anomalies, renal anomalies, CDH, preaxial polydactyly, and six minor anomalies including mild ventriculomegaly, pyelectasis, and hypertelorism (Table 2).…”
