[Spinal cord compression disclosing rib hydatidosis].

The authors report an exceptional case of spinal compression following an isolate rib hydatidosis. The CT scan has suspected the diagnosis. The authors recall the anatomoclinic features and specify the radiologic aspects of the osseous hydatidosis, especially the rib's localization which is very rare. MR imaging in addition of its diagnosis role showing a very evocative cyst images, is the exam of choice in order to appreciate the disease's extent and the degree of medular sufferance.

[Granulocytic sarcoma presenting as an epidural mass with spinal cord compression].

A 73-year-old man was admitted because of back pain and paralysis of the lower extremities. Magnetic resonance imaging of the spine at the Th4-6 level, obtained after gadolinium injection, demonstrated abnormal signal intensity within the Th5-6 vertebral bodies and an extradural soft-tissue mass on the right posterior side of the spinal canal, compressing the thecal sac. The patient underwent prompt decompression with laminectomy, but this was unsuccessful. A biopsy sample of the mass revealed the histological features of granulocytic sarcoma, including diffuse infiltration of numerous cells containing cytoplasmic granules and immunohistochemical positivity for myeloperoxidase. Two months later, a subcutaneous soft-tissue mass appeared at the anterior chest wall, and this was confirmed to be granulocytic sarcoma by microscopic examination. Both of these tumors were radiosensitive, but the patient died of septic shock. Granulocytic sarcoma usually occurs in association with leukemia or other myeloproliferative disorders. However, it is rarely found before leukemia becomes evident in the peripheral blood or bone marrow; only eight such instances have been reported previously.

Spinal cord compression caused by extradural arachnoid cysts. Clinical examples and review.

Most spinal arachnoid cysts are asymptomatic and detected incidentally during magnetic resonance imaging or myelography. The etiology of intraspinal arachnoid cyst is not yet clear. We present two children with three spinal extradural arachnoid cysts and each cyst protruded from a separate dura defect. In both patients, plain radiographs demonstrated widening of the interpedicular distance, which suggested progressive widening of the spinal bony canal. Limited laminectomy was performed to remove the intraspinal cysts. Separate dura defects, the apparent predisposing factors, were also found and repaired. The patients completely recovered neurologically. Radical cyst removal and dura defect closure are the surgical intervention of choice in patients with symptomatic extradural arachnoid cyst.

Multiple vertebral hemangiomas resembling metastases with spinal cord compression.

A 58-year-old woman with spastic paraparesis had bony hemangiomas involving the spine, sacrum, and skull. Multiple bony lesions, paravertebral mass, abnormal serum protein levels, and myelopathy suggested multiple myeloma or metastatic neoplasm. Decompressive laminectomy demonstrated a benign capillary hemangioma.

Spinal cord compression due to carcinoid metastasis.

A case of cord compression secondary to the carcinoid syndrome is reported. The patient made an excellent response to surgical treatment, emphasizing that active management of this unusual complication should be considered.

LacZ-expressing olfactory ensheathing cells do not associate with myelinated axons after implantation into the compressed spinal cord.

Studies have shown that implanting olfactory ensheathing cells (OECs) may be a promising therapeutic strategy to promote functional recovery after spinal cord injury. Several fundamental questions remain, however, regarding their in vivo interactions in the damaged spinal cord. We have induced a clip compression injury at the T10 level of the spinal cord in adult rats. After a delay of 1 week, OECs isolated from embryonic day 18 rats were implanted into the cystic cavity that had formed at the site of injury. Before implantation, OECs were infected with a LacZ-expressing retrovirus. At 3 weeks after implantation, LacZ-expressing OECs survived the implantation procedure and remained localized to the cystic cavity. At the electron microscopic level, the cystic cavity had clusters of LacZ-expressing OECs and numerous Schwann cells lacking LacZ expression. Although labeled OECs made no direct contact with axons, unlabeled Schwann cells were associated with either a single myelinated axon or multiple unmyelinated axons. Positively labeled OEC processes often enveloped multiple Schwann cell-axon units. These observations suggest that the role of OECs as the primary mediators of the beneficial effects on axon growth, myelination, and functional recovery after spinal cord injury may require re-evaluation.

Thoracic spinal cord compression caused by diffuse idiopathic skeletal hyperostosis (DISH).

Diffuse idiopathic skeletal hyperostosis (DISH) is now recognized with increasing frequency in the elderly population. Whilst usually a relatively asymptomatic process, serious neurological sequelae have been reported. A previously unreported complication, severe focal thoracic canal stenosis, is presented. Attention is drawn to the need for full assessment of the whole spine by CT myelography in patients presenting with evidence of myelopathy.
