Respiratory distress associated with bilateral nasolacrimal duct cysts.

Nasolacrimal duct system cysts with intranasal extension is a rarely reported cause of respiratory distress in the newborn. Nine often previously reported patients have demonstrated a paranasal mass on examination. Most of these patients have been female and most have required surgical intervention to relieve the obstruction. We present a case of a male newborn with bilateral NLDS cysts with intranasal extension causing respiratory distress, and no evidence of paranasal mass on examination. Nasal endoscopy is essential in the work-up of all patients with nasal obstruction and respiratory distress. The MRI scan was used in the diagnostic work-up to further evaluate the condition. The NLDS cysts with nasal extension resolved spontaneously.
