Osteoid osteoma of the neck of the femur simulating the lumboradicular syndrome (2 case reports).
Two cases are described of patients aged 17 and 19 years who presented with symptoms suggesting a lumboradicular syndrome. Many radiographs had been negative during the 3 years since symptoms appeared. Small osteoid osteomas were found in the neck of the femur with very little surrounding sclerosis. Clinical examination of the hips was normal. Removal of the tumours cured the symptoms. It is suggested that the numerous non-myelinated nerve fibres in the "nidus" of the tumours could have been responsible for this unusual clinical picture.
