Radiation Induced

✓ Malignant triton tumor (MTT) is a variant of malignant peripheral nerve sheath tumors. The authors report a case of radiation-induced MTT in a patient with severe cervicothoracic cord compression and review the related literature. This 36-year-old man presented with pain and weakness in his left arm. His medical history was significant for a biopsy procedure involving the sampling of an aneurysmal bone cyst located at T1–3 near the left lung apex; this was performed 6 years prior to presentation and was followed by radiotherapy. Neurological examination demonstrated radicular findings involving the left C-8 and T-1 nerve roots. Neuroimaging studies revealed a large mass lesion extending from C-6 to T-2 along the vertebral column, invading the upper thoracic cavity and the adjacent lung apex, and infiltrating the paravertebral muscles. A subtotal resection was performed, but the tumor regrew extensively within a short time. It invaded the spinal canal and caused significant cord compression. The patient underwent surgery two more times for tumor debulking and to relieve progressive airway and spinal canal compromise. He eventually became quadriplegic, however, and died 13 months after diagnosis of MTT. This is the seventh case of radiation-induced MTT and the fifth of MTT with spinal canal involvement to be reported in the literature.

✓ Articular cysts of the atlantoaxial joint are infrequently described and probably an underreported cause of upper cervical spinal cord compression. The authors report on two patients with cysts located posteriorly of the dens in whom a C-1 and partial C-2 hemilaminectomy with subtotal resection of the cyst provided adequate and stable decompression 1 year postoperatively. The clinical and magnetic resonance imaging features and the surgical approach are discussed after a review of the literature.

✓ The author reports the successful treatment of a case of irreducile atlantoaxial dislocation due to separation of the dens and secondary arthritic changes causing sagittal narrowing of the atlanto-axial spinal canal to 3 mm. Complete myelography obstruction was present. A one-stage posterior decompression of the foramen magnum and atlas was performed and occipito-cervical fixation accomplished by wire encased in acrylic plastic.

Preoperative Examination

Neurological symptoms in Scheuermann’s disease are very rare, only a few dozen cases have been described. The main causes of spinal cord compression with the development of neurological symptoms in spinal deformities due to Scheuermann’s disease are compression by the anterior wall of the spinal canal, together with the dorsal leaflet of the dura mater, intervertebral hernia, and extradural bone cyst. The review provides a description of 38 clinical observations found in the literature. Compressing factors can also be spinal epidural lipomatosis and a displaced fragment of the annular apophysis. Scheuermann’s disease can be combined with syringomyelia. The magnitude of the kyphotic deformity does not correlate with the severity of neurological symptoms. Preoperative examination of a patient with Scheuermann’s disease should include methods that allow visualizing the condition of the spinal canal and its contents.

✓ Computerized tomography metrizamide myelography was performed in 46 patients with acute, nonpenetrating cervical spinal cord injuries. By visualizing the spinal canal, spinal cord, and any compressive lesion, the study proved valuable in the decision as to whether surgical decompression was indicated and what approach should be used. Eleven patients were found to have significant spinal cord compression, 10 of whom were treated surgically. The technique, results, and complications resulting from the study are discussed.

Object. It is known that the spinal cord can sustain traumatic injury without associated injury of the spinal column in some conditions, such as a flexible spinal column or preexisting narrowed spinal canal. The purpose of this study was to characterize the clinical features and to understand the mechanisms in cases of acute cervical cord injury in which fracture or dislocation of the cervical spine has not occurred. Methods. Eighty-nine patients who sustained an acute cervical cord injury were treated in our hospitals between 1990 and 1998. In 42 patients (47%) no bone injuries of the cervical spine were demonstrated, and this group was retrospectively analyzed. There were 35 men and seven women, aged 19 to 81 years (mean 58.9 years). The initial neurological examination indicated complete injury in five patients, whereas incomplete injury was demonstrated in 37. In the majority of the patients (90%) the authors found degenerative changes of the cervical spine such as spondylosis (22 cases) or ossification of the posterior longitudinal ligament (16 cases). The mean sagittal diameter of the cervical spinal canal, as measured on computerized tomography scans, was significantly narrower than that obtained in the control patients. Magnetic resonance (MR) imaging revealed spinal cord compression in 93% and paravertebral soft-tissue injuries in 58% of the patients. Conclusions. Degenerative changes of the cervical spine and developmental narrowing of the spinal canal are important preexisting factors. In the acute stage MR imaging is useful to understand the level and mechanisms of spinal cord injury. The fact that a significant number of the patients were found to have spinal cord compression despite the absence of bone injuries of the spinal column indicates that future investigations into surgical treatment of this type of injury are necessary.

Good Agreement

✓ A method is presented for measuring the true sagittal diameter of the cervical spinal canal on routine lateral radiograms by the use of a midline perforated ruler. Sagittal measurements were made in 92 normal adults to establish a range of normal values. The lower and upper limits were 10 mm and 17 mm, respectively, at the levels of C-3 to C-7. Comparison of the results with the anatomical measurements of dried specimens showed good agreement. Four cases of cord compression were presented and the diagnostic significance of the method in cervical myelopathy was discussed.

✓ Long-term survivors of Hodgkin disease may develop second primary tumors caused by the mutagenic effects of radio- and chemotherapy. The authors describe the case of a 35-year-old woman who presented with an unusual meningioma of the cervical spine 9 years after undergoing combined-modality treatment for Hodgkin disease. To the authors' knowledge, this is the first report of spinal meningioma as a complication of such therapy. Whereas radiation-induced intracranial meningiomas are well described in the literature, treatment-induced meningiomas of the spine have not been widely recognized.
