Lumbar epidural lipomatosis causing neurogenic claudication in two obese patients

Two obese patients suffering from neurogenic claudication caused by lumbar epidural lipomatosis are described. Although lumbar epidural lipomatosis is most often related to prolonged use of steroid drugs, obesity has also been reported as a possible cause. Both CT and MRI can demonstrate excess epidural fat; because of the possibility of sagittal views MRI is to be preferred. In one of our patient with neurogenic claudication the excess epidural fat normalised completely after considerable weight reduction and symptoms resolved. Therefore weight reduction might be the initial therapy in an obese patient with symptomatic epidural lipomatosis. When weight reduction fails or when there are urgent clinical reasons, surgical removal of the excess amount of epidural fat should be considered.
