Whether a history of headache or "early" versus "late" ambulation (no bed rest or bed rest for 24 h) influence the occurrence of headache after lumbar iohexol myelography was studied by blinded interviews in 158 consecutive patients referred for elective lumbar myelography (LM) because of suspected lumbar disc prolapse or spinal stenosis. Headache after LM occurred more often in patients with a history of headache (57%) than in patients without such a history (29%), P < 0.001. Patients with normal myelographic findings complained of headache after LM more often (55%) than patients with abnormal myelograms (31%), P < 0.008. No difference in the incidence of headache after LM was demonstrated in early versus late ambulation.

Two hundred one consecutive patients with cancer pain who received intrathecal pain treatment between 1985 and 1993 were included in this retrospective study undertaken to test the hypothesis that epidural metastasis is a common cause of "refractory" cancer pain and that its presence may affect the efficacy and the complication rates of intraspinal pain treatment. Fifty-seven (approximately 28%) patients were investigated by metrizamide myelography, computerized tomography (CT), magnetic resonance imaging (MRI), laminectomy, or neurohistopathology. Epidural metastases were found in 40 (70%) and spinal stenosis in 33 (approximately 58%); 7 patients with total and 26 with partial occlusion of the spinal canal. Presence of epidural metastasis affected catheter insertion complications, daily dosages, and complications of the intrathecal pain treatment only when it was associated with spinal canal stenosis (partial or total). During the period of the intrathecal treatment, the patients with confirmed epidural metastasis and total spinal canal stenosis needed significantly (P < 0.05) higher daily doses of opioid (means = 77 +/- 103 versus 22 +/- 29 mg) and intrathecal bupivacaine (means = 65 +/- 44 versus 33 +/- 20 mg) and had significantly (P < 0.05) higher rates (14% versus 0%) of radicular pain at injection and poor distribution of analgesia than those without epidural metastasis and spinal canal stenosis. In contrast, the rate of occurrence of post-dural puncture headache was significantly (P < 0.05) lower in patients with partial (4%) and total (14%) spinal stenosis than in those without (29%). Unexpected paraplegia occurred in four patients and was due to accidental injury during attempted dural puncture (N = 1) and collapse (due to cerebrospinal fluid leakage leading to "medullary coning" of an unknown epidural metastasis (N = 3).

Paget's disease of bone is associated with involvement of the central and peripheral nervous system. The brain, spinal cord, cauda equina, spinal roots, and cranial nerves can be affected in Paget's disease due to their anatomic relationship to bone. Neurologic syndromes are uncommon but include headache, dementia, brain stem and cerebellar dysfunction, cranial neuropathies, myelopathy, cauda equina syndrome, and radiculopathies. The central complications result from pagetic involvement of the skull. Expansion of diseased bone can result in compression of cranial nerves as they exit their bony foramina. Softening of the skull leads to basilar invagination with compression of the brain stem, cerebellum, and lower cranial nerves. Brain stem compression can cause hydrocephalus. Rarely, there is direct compression of the brain from acute epidural hematoma or hypertrophy of the calvarium. Myelopathy, cauda equina syndrome, and radiculopathies most commonly result from hypertrophy of the spine with direct compression. Spinal stenosis can also result from ossification of extradural structures or pathologic fractures. Ischemia from vascular compression or a steal syndrome has also been described. Neurologic complications rarely occur due to sarcomatous transformation of pagetic bone. Magnetic resonance imaging (MRI), computerized tomography (CT)-myelography, and bone X-rays are helpful to localize the lesion and direct therapy. Treatment options include surgical decompression, ventricular shunt placement, and medical management with calcitonin and/or the bisphosphonates. The selection of treatment will vary depending upon the rate of progression and the severity of the neurologic deficit.

Chronic axial neck pain and cervicogenic headache are common problems, and there have been significant advances in the understanding of the etiology and treatment of each. The severity and duration of pain drives the process. For patients who have had slight to moderate pain that has been present for less than 6 months and have no significant motor loss, strength training of anterior, posterior, and interscapular muscle groups coupled with body mechanics training is prescribed. After 8 weeks, if the patient is better, exercises are continued at home or in a gym. If the patient is not better, physical therapy is continued for up to 8 more weeks. In patients with motor loss or severe pain, radiographs and magnetic resonance imaging (MRI) should be ordered at the initial visit. In patients with slight to moderate pain who are not better by 4 to 6 months, plain radiographs of the neck and MRI should be ordered. Based on the results, a spinal injection is usually prescribed. If MRI reveals spinal stenosis of the central or lateral canal, or a disc herniation, an epidural corticosteroid injection should be ordered. If the epidural provides good relief, the patient can be referred for more aggressive physical therapy and repeat the epidural as needed up to a maximum of three times. If there is no pathology within the canal, medial branch blocks and intra-articular steroid injections can be ordered based on the joints that are most tender or where disc space narrowing is greatest, or MRI or radiographs are recommended. If there is excellent relief from the medial branch block and joint injections, repeat when the steroids wear off. If there is good relief again, but pain recurs, medial branch radiofrequency neurotomy is recommended. For patients with one or two level disc degeneration that has not responded, a psychologic evaluation and discography is recommended. If there are no significant psychologic abnormalities, and one or two (rarely three) painful discs, surgical consultation is recommended. Adjunctive low-dose opioid analgesics, nonsteroidal anti-inflammatory drugs, and perhaps tricyclic antidepressants are used to supplement the program at mid- and late stages.

Recent reports indicate that cerebellar hemorrhage after spinal surgery is infrequent, but it is an important and preventable problem. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanisms are unknown. This report details the case of a 48-year-old woman who developed remote cerebellar hemorrhage after spinal surgery. The patient presented with a herniated lumbar disc, spinal stenosis, and spondylolisthesis, and underwent multiple-level laminectomy, discectomy, and transpedicular fixation. The dura mater was opened accidentally during the operation. There were no neurologic deficits in the early postoperative period; however, 12 h postsurgery the patient complained of headache. This became more severe, and developed progressive dysarthria and vomiting as well. Computed tomography demonstrated small sites of remote cerebellar hemorrhage in both cerebellar hemispheres. The patient was treated medically, and was discharged in good condition. At 6 months after surgery, she was neurologically normal. The case is discussed in relation to the ten previous cases of remote cerebellar hemorrhage documented in the literature. The only possible etiological factors identified in the reported case were opening of the dura and large-volume cerebrospinal fluid loss.

Congenital lumbar spinal stenosis is an uncommon condition that is often asymptomatic in young adults. Herein, we document the first reported occurrence of acute radicular back pain and associated congenital lumbar spinal stenosis in a healthy 24-year-old woman undergoing an epidural blood patch for treatment of a post-dural puncture headache related to an accidental dural puncture sustained during placement of a labor epidural catheter. The acute pain symptoms were elicited twice with injection of less than 1 mL of fluid into the epidural space during the fluoroscopically assisted epidural blood patch. Subsequent magnetic resonance imaging of the lumbar spine demonstrated shortened pedicle length consistent with severe congenital lumbar spinal stenosis and prominent epidural fat. We speculate that the transient increase in pressure within the epidural compartment following injection of a small amount of fluid could have compressed neural structures resulting in severe radicular pain. The prominent epidural fat could have prevented rapid disbursement of the injected fluid which could have further served to propagate the pressure increase throughout the epidural compartment. The unique radiographic features of congenital spinal stenosis could predispose some patients with this unrecognized condition to develop acute pain upon injection of a small amount of fluid into the epidural compartment. Unrecognized congenital lumbar spinal stenosis is an important addition to the differential diagnosis of acute radicular pain elicited during an epidural blood patch in previously asymptomatic patients.

3 women aged 75, 75 and 65 years, respectively, were referred to an outpatient clinic for medically unexplained symptoms (MUS). These cases illustrate the heterogeneity and complexity of MUS in elderly patients, which requires broad, multidisciplinary clinical examination by a geriatrician, psychiatrist and psychologist. The first patient presented with persistent pain in the lower back and legs. Examination revealed a spinal stenosis, which was treated surgically; symptoms subsequently resolved. The second patient had chronic abdominal pain and constipation in combination with depression. She was diagnosed with a severe depressive disorder. After adequate drug treatment, her mood improved and the somatic symptoms disappeared. The third patient complained of headache and feared that she may have a brain tumour. There was no somatic diagnosis. She underwent cognitive behavioural group therapy, which substantially improved her functioning. These cases illustrate the diversity and complexity of MUS in elderly patients and underscore the diagnostic appropriateness of the biopsychosocial paradigm. A specialised multidisciplinary examination ensures accurate diagnosis and cognitive behavioural therapy.

Back pain is one of the most common patient complaints brought forth to physicians. Mechanical back pain accounts for 97% of cases, arising from spinal structures such as bone, ligaments, discs, joints, nerves, and meninges. Acute back pain in the absence of progressive neurologic deficits and other underlying nonmechanical causes may be treated conservatively, with specific emphasis on maintaining activity levels and function. Mechanical back pain persisting for more than 4 to 6 weeks may warrant further diagnostic testing and imaging. Common causes of mechanical back pain include spinal stenosis, herniated discs, zygapophysial joint pain, discogenic pain, vertebral fractures, sacroiliac joint pain, and myofascial pain. A wide variety of treatments are available, with different treatments specifically targeted toward different causes. A balanced approach, which takes into account patient psychosocial factors and incorporates multidisciplinary care, increases the likelihood of success from back pain interventions.

The common etiologies of pneumocephalus, presence of air in the intracranial cavity, are trauma and cranial surgery. Pneumocephalus after spinal surgery is an unusual postoperative complication. We report the case of a male 59-year-old man who developed a pneumacephalus after posterior lumbar surgery for spinal stenosis. Intraoperatively, a cerebrospinal fluid leak following a dural tear was noted and immediately repaired. The next day, the patient complained of headache and dizziness. Head and lumbar computed tomography scans revealed significant air in the frontal region, several cisterns, intraventricle, and extra-dural area in the spine canal. Symptoms were spontaneously resolved within 2 weeks with conservative management.

Posterior reversible encephalopathy syndrome (PRES) is an unfamiliar term to anesthesiologists, and this is characterized by neurologic symptoms that include mental change, headache, seizure and visual disturbance and also abnormal neuroimaging finding. A 71-year-old female patient was operated on for posterior decompression and total laminectomy under general anesthesia for the spinal stenosis. After the operation, she developed generalized tonic-clonic seizure and a stuporous mentality in the recovery room. The magnetic resonance imaging (MRI) revealed swelling and increased signal intensity at the deep gray nuclei, cerebral cortex and cerebellum. After one week, she returned to an alert mentality and then she was diagnosed with PRES. She was discharged without any neurologic deficit on postoperative day 20. This report describes our experience with PRES after spinal surgery was performed under general anesthesia on a suspected untreated hypertensive patient.
