[Epidural lipomatosis].

Abstract

UNLABELLED:

ONSET: Epidural lipomatosis is a rare disorder defined as a pathological overgrowth of normal epidural fat. It is more often associated with administration of exogenous steroid with variable duration and doses. Furthermore, it may occur in some patients in the absence of exposure to steroids but generally associated with obesity. Whatever the predisposing factor, the majority of these patients are men. The causal effect of epidural lipomatosis in the development of spinal cord or radicular compression is generally well accepted.

DIAGNOSIS:

The diagnosis of epidural lipomatosis can be established by melography, computed tomography (CT) and magnetic resonance imaging (MRI). MRI is considered the imaging procedure of choice, allowing an assessment of the extent of lipomatosis and, as well as CT, an identification of the lipomatous tissue. Most cases of epidural lipomatosis with corticosteroid use occur in the thoracic region, while most idiopathic cases occur in the lumbar region.

TREATMENT:

Management of treatment depends on the severity of the neurological signs and the patient's background. The most common treatment for epidural lipomatosis with corticosteroid use consists in surgical decompression but with a high risk of postoperative mortality. In some cases however, medical treatment includes corticosteroid withdrawal or reduction and calorie restriction, leading to clinical improvement. Treatment for idiopathic epidural lipomatosis is more often medical, based on weight loss and physical therapy with generally successful outcome. The pathogenesis of epidural lipomatosis remains unknown but different suggested hypotheses may lead to a metabolic disorder as the underlying cause.
