RESUMEN
The authors report a rare and difficult case of hydatic cyst. The case was rare due to the location of the hydatic disease in the upper mediastinum and because of the onset of the disease with a complication: a spinal cord compression syndrome produced by the migration of the hydatic cyst into the spinal channel. The case was difficult because of the diagnostic problems--especially to establish the topography of the lesion and surgical management.

The mesenchymal repair process of the connective tissue in the surgical wound following lumbar laminectomy presents three aspects: postoperative epidural scar, heterotopic bone formation in the epidural scar and vertebral hyperostosis around laminectomy. Twelve cases of lumbar spine hyperostosis consecutive to laminectomy, confirmed by x-ray findings and surgery are presented. The main symptom at presentation was a recurrent sciatic neuritis. Lumbo-sacral spine films showed a "bright" focal condensation in the previous surgical. Lamina inferior and superior and the articular facets were hypertrophic. Surgery confirmed the hyperostosis and compressive lumbar spine stenosis or foramen stenosis.
