Dacryocystocele is an uncommon condition presenting at birth as a bluish swelling approximately 1 cm in diameter located below and nasal to the medial canthus. It represents a cystic swelling of the lacrimal sac due to obstruction of the lacrimal drainage system both above and below the sac. The average age when the lacrimal duct becomes patent is the eighth intrauterine month. If this does not occur, a dacryocystocele can result. Dacryocystocele is also referred to in the literature as mucocele, dacryocele, and amniocele of the lacrimal sac. We report a case of a dacryocystocele detected sonographically during pregnancy.
泪囊膨出是一种罕见的出生时即出现的病症，表现为在内眦下方和鼻侧有一个直径约1厘米的蓝色肿胀。它代表泪囊因泪道引流系统在泪囊上方和下方均受阻而出现的囊性肿胀。泪道通常在子宫内第八个月时开通。如果未开通，则可能导致泪囊膨出。泪囊膨出在文献中也被称为泪囊黏液囊肿、泪囊肿和泪囊羊膜囊肿。我们报告一例在孕期经超声检查发现的泪囊膨出病例。
