Regression of the radiological changes of Gaucher's disease following bone marrow transplantation

Seven children with Type I Gaucher's disease have been treated with bone marrow transplantation (BMT). One patient died from the complications of BMT. In five patients computed tomography (CT) of the femora showed initially high attenuation in the marrow, returning towards normal after successful BMT. One of these patients also showed clearing of pulmonary infiltrates following treatment. In the first patient in the series no pre-transplant CT measurements were carried out but plain radiographs have demonstrated a return to normal shape of her femora 21/2 years after BMT. It is hoped that CT of the marrow cavities may provide a simple, non-invasive method for monitoring progress following BMT.
