Gall stones in children have been commonly described in hereditary spherocytosis and sickle cell anaemia. In North India thalassemia is the commonest haemolytic anaemia. We studied the incidence of gall stones sonographically in children with thalassemia major. Of the 64 multitransfused children with thalassemia major studied (age range 5-20 years) none had symptoms of biliary colic or evidence of gall stones on sonography. The study has demonstrated that patients with thalassemia major are not prone to develop gall stones.
