We report a case of a newborn with unilateral laryngeal paralysis due to congenital varicella syndrome. The patient needed neonatal resuscitation with positive pressure ventilation for severe respiratory failure. Fiberoptic bronchoscopy showed left unilateral laryngeal paralysis. From the first week of life he presented left Horner's syndrome and difficult swallowing. He was hospitalised during the first 3 months of life for recurrent aspiration pneumonia and failure to thrive. At 11 months an ophthalmic evaluation with Ret-Cam showed a chorioretinal scar in the macular region that allowed the final diagnosis.
