1/212. Spinal subdural hematoma: a rare complication of lumbar puncture. Case report and review of the literature.Spinal subdural hematoma, though rare, is an established complication of lumbar puncture. A young man with persistent back and neck pain after a traumatic lumbar puncture for the diagnosis of lymphocytic meningitis is presented. A diagnosis of spinal subdural hematoma at T2 to T8 levels without significant spinal cord compression was confirmed by magnetic resonance imaging. Symptoms resolved after one month of analgesics and muscle relaxants.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
2/212. The longer term effect of pulsed radiofrequency for neuropathic pain.pulse radiofrequency has been recently described as a technique to apply a relatively high voltage near a nerve but without the usual effects of a rise in temperature or subsequent nerve injury. In this set of case reports, the effect of pulsed radiofrequency (PRF) is described in patients with neuropathic pain syndromes which have been poorly controlled with other oral and invasive treatments. Whilst anecdotal, the results have been remarkable and should encourage further research into this technique. Observations from the basic science tend to support the concept that PRF may induce some sort of long-term depression in the spinal cord.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
3/212. Idiopathic localized hydromyelia: dilatation of the central canal of the spinal cord of probable congenital origin.Three adult patients are reported with asymptomatic localized widening of the central canal of the spinal cord. These patients were followed for a period of 24 years by imaging and/or clinical history and physical examination without evidence of signs or symptoms related to the spinal cord. This condition probably represents persistence into adult life of a fetal configuration of the central canal of the spinal cord. This process may be termed "idiopathic localized hydromyelia" to distinguish it from syringomyelia secondary to such causes as Chiari malformation, trauma, infection, or neoplasm.- - - - - - - - - - ranking = 3.5678185555456keywords = spinal, canal (Clic here for more details about this article) |
4/212. back pain and collapse associated with receding subarachnoid blockade.PURPOSE: back pain and sudden loss of consciousness during recovery from spinal anesthesia are rare. Severe pain may raise fears of serious neurological damage and result in inappropriate management. Bladder distention may present in this way and clinicians should be alert to this possibility and communicate this to nursing staff. CLINICAL FEATURES: A lumbar spinal anesthetic was performed during a volunteer study, using 15 mg hyperbaric bupivacaine in a healthy 31 yr old man. During recovery, five hours later, as the block regressed to the L1-2 level, he complained of acute, severe back pain and briefly lost consciousness secondary to profound bradycardia. Bladder cathetherization yielded 900 mL urine with immediate and complete relief of symptoms. CONCLUSION: Severe pain secondary to bladder overdistention in the presence of neuroaxial blockade may be referred to the thoracolumbar area, mediated by intact sympathetic afferents. As the saccral parasympathetic supply remains paralyzed, there is no subjective sensation of bladder stretching. If untreated, bladder distention can lead to excessive supraspinal parasympathetic outflow resulting in vasovagal syncope.- - - - - - - - - - ranking = 1.5keywords = spinal (Clic here for more details about this article) |
5/212. A 15-year-old with back pain, fever, and leg numbness.Spinal epidural abscess (SEA) is an uncommon entity. We report an adolescent presenting with fever and back pain beginning 3 months after a leg abscess. This case highlights several important aspects of the diagnosis and care of patients with SEA. As illustrated by this case, plain radiographs and computed tomography of the spine can miss the diagnosis, thus when spinal epidural abscess is suspected, magnetic resonance imaging is the imaging modality of choice. Epidural abscesses most commonly arise from hematological dissemination, with staphylococcus aureus being the most often cultured organism. Surgical intervention early combined with the administration of proper antibiotics leads to the best outcome.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
6/212. Spinal epidural abscess complicating chronic epidural analgesia in 11 cancer patients: clinical findings and magnetic resonance imaging.We reviewed the records of all patients who had received an epidural catheter for management of chronic cancer pain in a 3-year period (1993-1996). patients with nervous system infections were identified, and pertinent clinical, radiological (magnetic resonance imaging), and bacteriological data were analyzed. We identified 11 patients who developed spinal epidural abscess (SEA). All of these had back pain; radicular signs occurred in seven patients and spinal cord compression in two patients. magnetic resonance imaging revealed SEA in all 11 patients. SEA was iso- to hypointense on T1-weighted images and hyperintense on T2-weighted images relative to spinal cord. After gadolinium administration seven lesions showed characteristic rim enhancement while three showed minimal enhancement. No signs of diskitis or osteomyelitis were present, and the abscess was always localized to the posterior epidural space. Cultures were positive in all cases and revealed staphylococcus epidermidis in eight and S. aureus in three. All patients were treated with intravenous antibiotics, and four had an additional decompressive laminectomy. Two patients died within 1 week of diagnosis from overwhelming septicemia despite apparently adequate antibiotic treatment. Within 4 weeks after diagnosis of SEA two patients died from widely metastatic disease, although infection may have contributed. One patient developed septicemia while receiving appropriate antibiotics and underwent emergency laminectomy. The neurological deficits recovered in all patients who survived the acute infectious episode. We conclude that patients with chronic epidural catheters for cancer pain require prompt neurological evaluation and magnetic resonance imaging when SEA is suspected. Early evaluation and treatment may lead to full recovery.- - - - - - - - - - ranking = 1.5keywords = spinal (Clic here for more details about this article) |
7/212. Cranial nerve palsy and intracranial subdural hematoma following implantation of intrathecal drug delivery device.BACKGROUND AND OBJECTIVES: Complications related to cerebrospinal fluid (CSF) leak and low CSF pressure can occur following placement of an intrathecal drug delivery device. methods: A 58-year-old man with chronic, intractable lower back pain underwent implantation of an intrathecal drug delivery device. On the fourth postoperative day, he developed a postural headache and diplopia with findings compatible with left sixth cranial nerve palsy. The headache subsequently became constant and nonpostural. Cranial magnetic resonance imaging was obtained that showed the presence of a posterior subdural intracranial hematoma. Conservative treatment for postdural puncture headache did not improve the symptomatology. Therefore, an epidural blood patch was performed that produced rapid improvement and eventual resolution of symptoms. CONCLUSIONS: Intrathecal catheter implantation can result in CSF loss that might not resolve promptly with conservative therapy. In this case, epidural blood patch proved to be a safe and effective form of treatment.- - - - - - - - - - ranking = 0.5keywords = spinal (Clic here for more details about this article) |
8/212. A child with neurofibromatosis-1 and a lumbar epidural arteriovenous malformation.A 10-year-old child with neurofibromatosis-1 was evaluated for progressive lumbar scoliosis, back pain, and foot numbness. magnetic resonance imaging showed several lumbar intraspinal and extraspinal masses consistent with neurofibromas. The mass at L3-L5 compressed the thecal sac and was thought to be the source of the symptoms. On operative exploration, a lumbar epidural arteriovenous malformation was found, which was removed in its entirety. The child's back pain and foot numbness resolved. Epidural arteriovenous malformations in patients with neurofibromatosis-1 are rare and have been reported only in the cervical spine. Our finding of a lumbar epidural arteriovenous malformation in a child with neurofibromatosis-1 demonstrates that vascular anomalies can be present throughout the spine of patients with neurofibromatosis-1 and should be considered in the differential diagnosis of any neurofibromatosis-1-related epidural mass.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
9/212. Persistent or severe back pain and stiffness are ominous symptoms requiring prompt attention.BACKGROUND: Children with severe or persistent back pain and stiffness often have an underlying organic cause but there is a large differential diagnosis, examination may be difficult and the problem is relatively rare in general paediatric practice. These difficulties appeared to lead to delays in diagnosis and management of children with this problem. OBJECTIVES: To provide an approach to the diagnosis and management children with severe or persistent back pain or stiffness based on our clinical experience and the literature. METHODOLOGY: The case histories of 10 children with severe back pain seen by the authors over a 5-year period were reviewed. They were chosen as illustrative examples of the diagnostic and management problems and did not represent a systematic review of all cases seen by the authors over that time. RESULTS: Underlying causes included infection, inflammation, neoplasm, trauma and vascular malformation. Four of the children had spinal cord compression which required urgent decompression. There was one child with a conversion disorder but three children with organic disease were initially felt to have a conversion disorder. Investigations generally proceeded relatively slowly and the problem was not regarded as a semi-urgent situation carrying the risk of permanent paraplegia. magnetic resonance imaging (MRI) scan of the spine was the investigation of choice. CONCLUSION: Children with severe or persistent back pain and stiffness have a wide variety of underlying causes. The possibility of underlying spinal cord compression should always be considered in children with this presentation. If the diagnosis is not obvious, MRI scan of the spine should be arranged without delay.- - - - - - - - - - ranking = 1keywords = spinal (Clic here for more details about this article) |
10/212. Postoperative synergistic gangrene after spinal fusion.STUDY DESIGN: A case of synergistic necrotizing gangrenous fasciitis after spinal surgery is reported. OBJECTIVES: To describe this unusual complication, explain the rationale of treatment, and increase awareness of this serious postoperative complication. SUMMARY OF BACKGROUND DATA: Although several cases of postoperative synergistic necrotizing fasciitis have been reported, there are no previously reported cases of this condition after spinal surgery. methods: A rapidly progressive necrotizing spinal wound infection after fusion for degenerative disc disease was treated in a 39-year-old man. RESULTS: The infection was successfully treated with serial debridements, appropriate antibiotics, and hyperbaric wound oxygenation. CONCLUSIONS: The authors suggest adherence to the fundamental principles of treatment including radical surgical debridement and appropriate antibiosis for necrotizing gangrene after spinal surgery. In evaluation of aggressive spinal wound infections, diagnosis of synergistic necrotizing fasciitis should be kept in mind. Although hyperbaric wound oxygenation was implemented as an adjunct and appeared to aid in controlling the infection, its effect on outcome is not clear.- - - - - - - - - - ranking = 4.5keywords = spinal (Clic here for more details about this article) |
