Obstructive neonatal respiratory distress: infected pyriform sinus cyst.
Infected lateral cervical cysts in newborn are rare. We present the case of a baby born at 41 weeks of gestation. At day 3, persistent cyanosis was noted, and a mass appeared in the left cervical region next to the sternocleidomastoid muscle. No cutaneous sinus was visible. Ultrasound imaging showed no sign of blood flow within the mass and no septae. The mass extended down to the aortic arch and pushed the trachea to the right. A cervical lymphangioma was first suspected. Puncture of the mass evacuated 80 mL of pus, and a drain was put in place. Opacification through the drain showed a tract originating from the left pyriform fossa. Preoperative laryngoscopy and catheterization of the fistula tract confirmed the diagnosis. The cyst was totally excised up to the sinus with the assistance of a guidewire inserted orally through a rigid laryngoscope. This is a rare case of an infected pyriform sinus cyst in the neonatal period.
