1/360. 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. ( info)

2/360. Laser-assisted diskectomy performed by an internist resulting in cauda equina syndrome.

    An internist performed percutaneous laser-assisted diskectomies (PLADs) on a patient with a sequestrated disc and stenosis. Subspecialists who perform PLADs should be trained in patient selection and lumbar diskectomy techniques. chymopapain, percutaneous nucleotome-assisted diskectomy, and PLADs are alternatives to microdiskectomy for the management of lumbar disc herniations. PLADs were performed at the L4-5/L5-S1 levels in a 38-year-old woman with magnetic resonance (MR)-documented L4-5 stenosis and disc disease. After PLADs, she developed a subacute cauda equina syndrome. Two months later, a neurosurgeon performed an L4-5 coronal hemilaminectomy with diskectomy. Within 6 postoperative weeks, she was neurologically intact. Only specialists trained in the selection, neurodiagnostic, and surgical management of lumbar disc disease should perform PLADs. ( info)

3/360. 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. ( info)

4/360. clostridium perfringens: a rare cause of postoperative spinal surgery meningitis.

    BACKGROUND: clostridium perfringens is a rare cause of central nervous system infections, particularly meningitis. The case of a 76-year-old man who developed fatal C. perfringens meningitis after routine decompressive laminectomy for spinal stenosis is described. CASE REPORT: Twelve days after surgery the patient presented with pain and serosangiunous drainage from the surgical incision site. A swab of the drainage revealed Gram-positive bacilli; MRI of the lumbosacral spine showed the appearance of air around the laminectomy site. The patient died within 6 hours of presentation. autopsy revealed acute cranial and spinal meningitis and choroid plexitis with organisms consistent with C. perfringens. CONCLUSION: No significant enteral pathology or source of endogenous infection was determined, suggesting postoperative wound contamination and meningeal seeding with this ubiquitous organism. Clostridial infection, although rare, should be considered in any patient with meningitis with a history of surgical intervention. survival with minimal neurological deficits was achieved in half of the previously reported cases.

5/360. A case of cervical myelopathy with developmental canal stenosis at the level of the atlas. A case report.

    The craniocervical junction is one of the most common sites of malformations. Only three cases of myelopathy due to hypoplasia of atlas have been reported previously. Among these malformations, the hypoplasia of atlas was first described by Wackenheim in 1974. Although developmental canal stenosis due to the hypoplasia of atlas seems to have a tendency of causing the cervical myelopathy, only three cases of cervical myelopathy due to this condition have been reported previously. A 77-year-old man with severe canal stenosis at the level of the atlas is reported. The clinical manifestations were 20-year history of progressive gait disturbance and paresis of both upper and lower extremities. The spinal cord was markedly compressed at the level of the atlas. The clinical manifestations improved after a resection of posterior arch of the atlas. ( info)

6/360. 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. ( info)

7/360. Nerve root herniation secondary to lumbar puncture in the patient with lumbar canal stenosis. A case report.

    STUDY DESIGN: A very rare case of nerve root herniation secondary to lumbar puncture is reported. OBJECTIVE: To describe the characteristic clinical features of this case and to discuss a mechanism of the nerve root herniation. SUMMARY OF BACKGROUND DATA: There has been no previous report of nerve root herniation secondary to lumbar puncture. methods: A 66-year-old woman who experienced intermittent claudication as a result of sciatic pain on her right side was evaluated by radiography and magnetic resonance imaging, the results of which demonstrated central-type canal stenosis at L4-L5. The right sciatic pain was exacerbated after lumbar puncture. myelography and subsequent computed tomography showed marked stenosis of the thecal sac that was eccentric to the left, unlike the previous magnetic resonance imaging finding. RESULTS: At surgery, a herniated nerve root was found through a small rent of the dorsocentral portion of the thecal sac at L4-L5, presenting a loop with epineural bleeding. The herniated nerve root was put back into the intrathecal space, and the dural tear was repaired. CONCLUSION: Lumbar puncture can be a cause of nerve root herniation in cases of lumbar canal stenosis. The puncture should not be carried out at an area of stenosis. ( info)

8/360. The effect of Lipo prostaglandin E1 on cauda equina blood flow in patients with lumbar spinal canal stenosis: myeloscopic observation.

    STUDY DESIGN: Myeloscopic examination was performed to observe the cauda equina in patients with lumbar spinal canal stenosis before and after treatment with Lipo prostaglandin E1, a strong peripheral vasodilator. OBJECTIVES: The purpose of this study was to clarify the effects of Lipo prostaglandin E1 on blood flow in the cauda equina in patients with lumbar spinal canal stenosis. SETTING: japan, Kagoshima methods: We performed myeloscopic observations of morphological changes in blood vessels running along the cauda equina in 11 patients with lumbar spinal canal stenosis before and after treatment with Lipo prostaglandin E1. RESULTS: In six of these patients, dilation of the running blood vessels was observed immediately after administration. In all of the patients who exhibited a dilation of vessels on the surface of the cauda equina, intermittent claudication and lower extremity pain and/or numbness lessened immediately after examination. However, none of the patients who exhibited no morphological changes in the vessels along the cauda equina after administration of Lipo prostaglandin E1 experienced any improvement of symptoms at the time of examination. CONCLUSION: Results of this study suggest that Lipo prostaglandin E1 may enhance blood flow in the cauda equina and improve clinical symptoms in some patients with lumbar spinal stenosis. ( info)

9/360. 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.

10/360. Anomaly of the axis causing cervical myelopathy. Case report.

    Although the craniovertebral junction is one of the most common sites at which anomalies develop, spina bifida occulta of the axis (C-2) associated with cervical myelopathy is extremely rare. The authors present the case of a 46-year-old man who developed progressive tetraparesis caused by a cervical canal stenosis at the level of the axis. The spinal cord was compressed by an invaginated bifid lamina of the axis. The patient made a remarkable recovery after undergoing decompressive laminectomy of C-3 and removal of the bifid posterior arch of the axis. ( info)
