A 5-day-old male infant was referred to us due to the observation of a dark-blue soft mass in the region of his left lacrimal sac (Figure 1).
Computed tomography scan images showing the dacryocystocele (arrows) in patient 1. The dacryocystocele formed consecutive nasal cysts (asterisks), which occluded the left inferior nasal meatus.
