Back pain caused by benign tumors and tumor-like lesions of the thoracolumbar spine.
Twenty-two patients with benign tumors or tumor-like lesions of the spine (vertebral echinococcal cysts, eosinophilic granuloma) presented with back pain and deformity. The duration of pain ranged from 1 to 6 years. Five patients had incomplete paraplegia at admission. Spine deformity was observed in patients with osteoid osteoma, osteoblastoma, hemangioma, and vertebral echinococcal involvement. All patients underwent clinical evaluation, laboratory studies, and histologic studies. Electromyogram studies were performed in patients who had a neurologic deficit or nerve root irritation. Imaging evaluation consisted of plain films, bone scans, computed tomography scans, and magnetic resonance imaging scans. Fifteen patients had lumbar involvement; 7 had thoracic involvement. For 18 patients, management included tumor excision and thorough debridement of the lesion. Spinal instrumentation and fusion were used to correct the deformity and treat the instability in 5 patients. Patients were followed for 1 to 8 years. Of the 5 patients with incomplete paraplegia, 4 recovered completely, and the fifth (who had spinal cord hemangioma) improved 2 grades on Frankel's scale. The remaining patients were disease free and returned to routine daily activities. Benign tumors or tumor-like lesions of the thoracolumbar or lumbar spine are very rare and easily misdiagnosed in patients with persistent back pain. Patients whose symptoms progress or fail to respond over an appropriate period of time should be evaluated further. Complete excision of the tumor followed by spinal instrumentation in the presence of deformity or instability is the treatment of choice.
