Hypocholesterolaemia in a child with familial hypercholesterolaemia.

A boy in early childhood with genetically confirmed familial hypercholesterolaemia was found to have an unusually low low-density lipoprotein cholesterol level. He had undergone a distal ileal resection and right hemicolectomy for ileal atresia and microcolon in the neonatal period. This case serves as a reminder of the surgical interventions sometimes used to treat severe hypercholesterolaemia in the pre-statin era.
