title: [2 benign bone lesions in a tubular bone: misinterpretation of clinical and radiological findings].
abstract: BACKGROUND
  Bone lesions are common at puberty. Most of them are detected by chance at examination for other reasons. The nonossifying fibroma does not produce any clinical symptoms and normally is diagnosed by chance. A spontaneous healing is discussed. The osteoid osteoma is characterized by its nocturnal pain and relief of pain at therapy with salicylates. Operative procedures are indicated for healing.
  
  
  METHODS
  A 12-year-old girl presented with radiological signs of a nonossifying fibroma. Because of local radionuclid uptake and clinical symptoms an operative procedure was carried out. Postoperative remaining pain resulted in radiological detection of a nearby osteoid osteoma and local operative therapy.
  
  
  CONCLUSIONS
  Two benign bone lesions at one tubular bone are an extremely rare situation. The clinical symptoms and the radionuclid uptake are misinterpretated and falsely assigned to the nonossifying fibroma. All clinical symptoms and radiological signs have to be correlate correctly with the diagnosis and consecutive therapy in order to avoid a misinterpretation of obvious clear radiological results.
