1/143. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/143. A single case report of healing through specific martial art therapy: comparison of MRI to clinical resolution in severe cervical stenosis: a case report.OBJECTIVES: A 76-year-old patient with chronic and severe spinal cord compression secondary to cervical stenosis, a cervical osteophyte, and a herniated intervertebral cervical disk had lasting resolution of symptoms after completing a specific, martial art-based, physical therapy program. We wanted to determine if there were structural changes in the cervical spine that could account for the prompt resolution of symptoms. DESIGN: A 76-year-old female completed 8 weeks of a specific, martial art-based, physical therapy. The pretherapy and posttherapy cervical magnetic resonance images (MRIs) were compared. A follow-up evaluation was done at 1 year. RESULTS: The patient was symptom-free within 8 weeks of the start of therapy. She remained symptom-free at 1 year follow-up evaluation. There were no obvious structural differences in the pretherapy and posttherapy MRI studies. CONCLUSIONS: Resolution of symptoms was directly related to the specific martial art therapy. However, there were no changes in the pretherapy and posttherapy MRI studies, suggesting a significant adaptation to the spinal compression had occurred. These data suggest a viable option to surgery in elderly patients with chronic and severe cervical spinal stenosis.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
3/143. Gz associated stenosis of the cervical spinal canal in fighter pilots.Previous magnetic resonance imaging (MRI) studies have shown that repeated exposure to Gz forces can cause premature degenerative changes of the cervical spine (i.e. a work-related disease). This paper reports on two clinical cases of Gz-associated degenerative cervical spinal stenosis caused by dorsal osteophytes in fighter pilots. Conventional x-rays and MRI were used to demonstrate narrowing of the cervical spinal canal. The first case was complicated by a C6-7 intervertebral disk prolapse and a congenitally narrow spinal canal. The second case involved progressive degenerative spinal stenosis in the C5-6 disk space which required surgery. The findings in this case were confirmed by surgery which showed posterior osteophytes and thickened ligaments compressing the cervical medulla. These two cases suggest that Gz forces can cause degenerative spinal stenosis of the cervical spine. Flight safety may be jeopardized if symptoms and signs of medullar compression occur during high Gz stress. It is recommended that student fighter pilots undergo conventional x-rays and MRI studies in order to screen out and reject candidates with a congenitally narrow spinal canal. These examination methods might be useful in fighter pilots' periodic medical check-ups in order to reveal acquired degenerative spinal stenosis.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
4/143. Symptomatic spinal epidural lipomatosis after local epidural corticosteroid injections: case report.OBJECTIVE AND IMPORTANCE: Spinal epidural lipomatosis, which causes symptomatic compression of neural elements, is a well known but uncommon complication of Cushing's syndrome. Spinal epidural lipomatosis has been reported frequently in association with chronic systemic corticosteroid therapy, but thus far only one case has been attributed to local epidural corticosteroid injections. CLINICAL PRESENTATION: We report another case of symptomatic spinal epidural lipomatosis after epidural corticosteroid injections. This is the first such case documented by magnetic resonance imaging and confirmed with surgical exploration. INTERVENTION: The patient's symptoms of neurogenic claudication resolved after lumbar laminectomy in the region of previous corticosteroid injections and the removal of epidural fat, which was compressing the thecal sac. CONCLUSION: This case should alert clinicians that epidural lipomatosis, which causes symptomatic thecal sac compression, is a possible complication, not only of systemic glucocorticoid therapy, but also of local epidural corticosteroid injections.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
5/143. ligamentum flavum hematoma in the lumbar spine.A patient who presented with symptoms suggestive of nerve root compression secondary to an extradural mass was found to have a hematoma in the ligamentum flavum. Pathological examination of surgical specimens revealed an old hemorrhage, and hemosiderin deposits around organized granulation tissue within the ligamentum flavum. Vessels within the ligamentum flavum had, presumably, ruptured during minor trauma when the patient stood up.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
6/143. Circumferential cervical surgery for spondylostenosis with kyphosis in two patients with athetoid cerebral palsy.BACKGROUND: patients with athetoid cerebral palsy may develop severe degenerative changes in the cervical spine decades earlier than their normal counterparts due to abnormal cervical motion. methods: Two patients, 48 and 52 years of age, presented with moderate to severe myelopathy (Nurick Grades IV and V). MR and 3-dimensional CT studies demonstrated severe spondylostenosis with kyphosis in both patients. This necessitated multilevel anterior corpectomy with fusion (C2-C7, C3-C7) using fibula and iliac crest autograft and Orion plating, followed by posterior wiring, fusion using Songer cables, and halo placement. RESULTS: Postoperatively, both patients improved, demonstrating only mild or mild to moderate (Nurick Grades II and III) residual myelopathy. Although both fused posteriorly within 3.5 months, the patient with the fibula graft developed a fracture of the anterior C7 body with mild anterior graft migration, and inferior plate extrusion into the C7-T1 interspace. However, because he has remained asymptomatic for 9 months postoperatively, without dysphagia, removal of the plate has not yet been necessary. CONCLUSIONS: patients with athetoid cerebral palsy should undergo early prospective cervical evaluations looking for impending cord compromise. When surgery is indicated, circumferential surgery offers the maximal degree of cord decompression and stabilization with the highest rate of fusion.- - - - - - - - - - ranking = 1.2067089778013keywords = compression, fracture (Clic here for more details about this article) |
7/143. Unilateral thoracic canal stenosis.Two unusual cases of thoracic spinal canal stenosis are reported. The cord compression was a result of unilateral hypertrophy of the lamina and facet joint.

10/143. Atlantal stenosis: a rare cause of quadriparesis in a child. Case report.The authors report the case of a 3-year-old boy who suffered from quadriparesis and respiratory distress after failing to execute a somersault properly. neuroimaging revealed spinal cord contusion with marked spinal canal stenosis at the level of the atlas. No subtle instability, occult fracture, or other congenital abnormalities were confirmed. Spinal cord contusion with marked canal stenosis is rare, and only several adult cases have been reported. Severe stenosis at the level of the atlas may predispose individuals to severe spinal cord contusion, as occurred in our patient after sustaining trivial trauma.- - - - - - - - - - ranking = 0.20670897780133keywords = fracture (Clic here for more details about this article) |
