Special Sono-Case: High-frequency ultrasound evaluation of a neonatal medial canthal mass suspicious for dacryocystocele.

Why this case matters

A dacryocystocele has a characteristic location but must be differentiated from vascular, inflammatory, encephalocele-related, and other congenital masses. Intranasal extension may also affect neonatal breathing.

The case covers

• Small-footprint high-frequency technique
• Relationship to the lacrimal sac and nasolacrimal duct
• Color Doppler and compression precautions
• Complications, differential diagnosis, and reporting
