Further evaluation revealed a right-sided cervicothoracic lymphatic malformation. At 13 weeks of age, the child underwent percutaneous intracystic sclerotherapy with a mixture of sodium tetradecyl sulphate and ethanol. Twenty-one weeks after initial treatment, ophthalmic examination showed complete resolution of the blepharoptosis and pupillary miosis. Percutaneous sclerotherapy not only effectively treated the space-occupying lymphatic malformation but also reversed the Horner syndrome that was presumably induced by neural tension (more likely) or compression.
