[Bourneville's disease of the bones or metastasis? Apropos of a case].

Tuberous sclerosis or Bourneville's disease is a phakomatosis with common but paucisymptomatic bone localisations. Some osseous lesions, of osteosclerotic type, can be radiologically diagnosed as primary or secondary malignant disorders. We describe a case of Bourneville's disease with bone involvement, radiologically characterized by osteosclerosis areas of the spine and the pelvis. Interestingly, bone scintiscan was normal. The absence of primary malignancy, the stability of control bone X-ray films, the clinical status and the family history, together with the pathognomonic radiological feature of the hands support the diagnosis of tuberous sclerosis with bone involvement.
