title: Benign tumors and tumorlike conditions of the spine. Radiological features, treatment, and results.
abstract: A series of 44 benign tumors and tumorlike conditions of the spine treated surgically between 1952 and 1982 is reported. We have focused on their radiodiagnosis, treatment, and long-term results. The radiologic features considered pathognomonic of skeletal tumors, and frequently found in tumors outside the spine, are less common in the spinal variety. In fact, the radiologic findings in spinal tumors are, as a rule, nonspecific. The long-term results in this series are considered satisfactory, despite two recurrences of a giant cell tumor and late malignant degeneration of an osteochondroma. The prognosis was good, and recurrence rare even after conservative excision of the lesion. More aggressive treatment is nonetheless recommended nowadays for giant cell tumors and osteoblastomas, even if vertebral stability has to be sacrificed and fusion performed, as this affords the best chance of permanent cure. Conservative excision without radiotherapy remains the treatment of choice for other benign tumors. Spinal instability is a serious risk especially in younger patients who have undergone radiotherapy and have residual neurological deficits. Provision should be made against this risk by planning a fixation procedure either in the same operation as ablative surgery or at a later stage.
