Congenital dacryocystocele with significant enlargement of the nasolacrimal duct diagnosed with computed tomography dacryocystography.

The authors successfully assessed the lacrimal systems of two patients with dacryocystocele based on dacryocystographic observations using computed tomographic scanning. The results showed that both the lacrimal sac and the nasolacrimal duct were largely distended, and the duct terminated in a closed cyst in the nasal cavity.
