Solitary involvement of the fourth thoracic vertebral body with eosinophilic granuloma and development of incomplete paraparesis.

This is a report of the case of a 9-year-old boy with solitary involvement of the fourth thoracic vertebral body with eosinophilic granuloma and development of neurologic deficits. Ventral decompression of the spinal cord, removal of the tumor tissue, and anterior arthrodesis succeeded in preventing an increase of the kyphotic deformity of the vertebral body. Complete reversal of the neurologic deficits was seen in the further course.
