We present a case of non-involuting congenital haemangioma (NICH) of the right eyelid which was present at birth as a purpuric macule but increased in size to cause significant obstruction of vision. At four years of age the lesion was treated with fluroscopic ultrasound-guided sclerotherapy using 0.5% sodium tetradecyl suphate foam and surgically debulked 16 days later. Histopathology was negative for glucose transporter-1 stain confirming the diagnosis. The residual segments were subsequently treated in three further sessions of sclerotherapy in the ensuing three years. This treatment approach resulted in a good cosmetic and functional outcome with no associated complications. To our knowledge, this is the first published case of a histologically confirmed NICH treated primarily with sclerotherapy.
