1/21. Presentation of intravascular lymphomatosis as lumbosacral polyradiculopathy.

    A 53-year-old man developed progressive sensory disturbance and weakness in the legs, sphincter disturbance, back pain, systemic symptoms, and pancytopenia. Electrophysiological tests indicated a widespread lumbosacral polyradiculopathy. Spinal magnetic resonance imaging and routine cerebrospinal fluid analysis showed minor nonspecific abnormalities. bone marrow and liver biopsies showed hemophagocytosis; and polymerase chain reaction of cerebrospinal fluid, bone marrow, and serum suggested active infection with human herpesvirus-6. autopsy revealed that his neurological symptoms resulted from intravascular lymphomatosis (angiotropic large cell lymphoma), a rare variant of lymphoma with predilection for the nervous system.

2/21. cauda equina syndrome secondary to idiopathic spinal epidural lipomatosis.

    STUDY DESIGN: Three cases of idiopathic epidural lipomatosis are reported. OBJECTIVES: Description of the relationship between spinal pathologic overgrowth of fat tissue and neurologic symptoms. SUMMARY OF BACKGROUND DATA: Idiopathic epidural lipomatosis is a very rare condition; it is usually secondary to chronic steroid therapy or endocrinopathic diseases. methods: Three men with a mean age of 58.5 years, who experienced intermittent claudication, bilateral radicular pain in both legs, and urinary dysfunction with hypoesthesia in the perineal region, were evaluated by plain radiography and magnetic resonance imaging, the results of which demonstrated a pathologic overgrowth of fat tissue in the spinal canal with a marked impingement of the dural sac. obesity, endocrinopathic diseases, and chronic steroid therapy were excluded for all patients. Surgical treatment was performed by wide multilevel laminectomies, fat debulking, and instrumented posterolateral fusion. RESULTS: After surgery there was a gradual improvement in symptoms and signs so that 2 years later the patients returned to daily activities and were neurologically normal. CONCLUSIONS: Spinal epidural lipomatosis can be a cause of back pain but rarely radicular impingement. magnetic resonance imaging is the procedure of choice. The treatment must be performed early by wide surgical decompression.

3/21. Posterior epidural migration of a lumbar disc fragment causing cauda equina syndrome: case report and review of the relevant literature.

    Posterior epidural migration (PEM) of free disc fragments is rare, and reported PEM patients usually presented with radicular signs. An uncommon case involving a patient with cauda equina syndrome due to PEM of a lumbar disc fragment is reported with a review of the literature. The patient described in this report presented with an acute cauda equina syndrome resulting from disc fragment migration at the L3-L4 level that occurred after traction therapy for his lower back pain. The radiological characteristics of the disc fragment were the posterior epidural location and the ring enhancement. A fenestration was performed and histologically confirmed sequestered disc material was removed. An early postoperative examination revealed that motor, sensory, urological, and sexual functions had been recovered. At late follow-up, the patient was doing well after 18 months. Sequestered disc fragments may occasionally migrate to the posterior epidural space of the dural sac. Definite diagnosis of posteriorly located disc fragments is difficult because the radiological images of disc fragments may mimic those of other more common posterior epidural lesions.

4/21. cauda equina syndrome in ankylosing spondylitis (the CES-AS syndrome): meta-analysis of outcomes after medical and surgical treatments.

    The cauda equina syndrome in ankylosing spondylitis (the CES-AS syndrome) is marked by slow, insidious progression and a high incidence of dural ectasia in the lumbosacral spine. A high index of suspicion for this problem must be maintained when evaluating the patient with ankylosing spondylitis with a history of incontinence and neurologic deficit on examination. There has been disagreement in the literature as to whether surgical treatment is warranted for this condition. A meta-analysis was thus performed comparing outcomes with treatment regimens. Our results suggest that leaving these patients untreated or treating with steroids alone is inappropriate. Nonsteroidal antiinflammatory drugs may improve back pain but do not improve neurologic deficit. Surgical treatment of the dural ectasia, either by lumboperitoneal shunting or laminectomy, may improve neurologic dysfunction or halt the progression of neurologic deficit.

5/21. Rapid, symptomatic enlargement of a lumbar juxtafacet cyst: case report.

    STUDY DESIGN: A case is reported in which a 45-year-old man developed cauda equina syndrome caused by enlargement of an L4-L5 juxtafacet cyst diagnosed 4 months earlier. OBJECTIVES: To highlight the short interval that can elapse between the discovery of a juxtafacet cyst and its remarkable progression. SUMMARY OF BACKGROUND DATA: Although juxtafacet cysts are acquired lesions, how long they take to develop remains unclear. hemorrhage is a well-known cause of rapid or even dramatic cyst enlargement. This is the first report providing magnetic resonance imaging evidence of rapid, remarkable enlargement of a nonhemorrhagic juxtafacet cyst. methods: The patient underwent conservative treatment for an L4-L5 right juxtafacet cyst diagnosed by magnetic resonance imaging during evaluation of posttraumatic lower back pain. Four months later, the patient presented with severe pain radiating down the right lateral leg, urinary retention, and impaired dorsal flexion of the right foot. Repeat magnetic resonance imaging showed the cyst now markedly enlarged and occupying almost the entire width of the canal. RESULTS: The cyst was removed, and the patient's symptoms abated. At 15 months after surgery, he is symptom-free. CONCLUSIONS: Juxtafacet cyst may occasionally enlarge and cause severe symptoms within months.

6/21. Primary spinal extradural hydatid cyst in a child: case report and review of the literature.

    Spinal hydatid cyst is a rare but serious condition. An 8-year-old boy presented with back pain, progressive weakness and numbness in both legs. magnetic resonance imaging (MRI) of the lumbar region showed a cystic lesion with regular contour located in extradural space. There was cerebrospinal fluid- (CSF-) like signal intensity on T1- and T2-weighted images. The lesion had excessively compressed the dural sac and caudal roots, and expanded to the L3 and L4 neural foramina. The case was explored with L2, L3, L4 laminectomy and the hydatid cyst was removed totally. The clinical presentation, diagnosis and surgical treatment of this rare case of spinal hydatid disease is discussed, and all available cases of primary extradural hydatid cyst reported in the literature are presented.

7/21. cauda equina syndrome following traction for acute sciatica.

    A case report of a patient who developed cauda equina syndrome following pelvic traction for acute sciatica is presented. A good outcome was obtained with prompt surgical decompression. This case illustrates the potential dangers of traction, which is frequently employed in the management of acute back pain.

8/21. chondroblastoma of the lumbar spine with cauda equina syndrome.

    STUDY DESIGN: Case report. OBJECTIVE: To describe the clinical presentations, radiological features and clinical progress of a rare case of chondroblastoma of the lumbar spine. SETTING: Regional Hospital, hong kong, china. METHOD: A 54-year-old male patient presented with low back pain and left sciatica. X-ray and MRI revealed tumour infiltration of the fifth lumbar vertebrae and left paraspinal muscles, which was found to be a chondroblastoma by repeated open biopsies. The tumour was removed surgically by combined anterior and posterior approaches, followed by spinal fusion and instrumentation. RESULTS: The anterior tricortical bone graft was complicated with fracture and nonunion. Surgical re-exploration confirmed local recurrence of tumour macroscopically and histologically. The patient developed symptoms and signs of cauda equina syndrome gradually despite repeated surgery and irradiation. The patient eventually died of complications of local recurrence and neurological deficit at 3 years and 8 months after the first operation. CONCLUSION: This is the first case report of chondroblastoma of the lumbar spine. The clinical profile of this patient and the evidence from the literature review suggests that spinal chondroblastoma has a very aggressive behaviour with high recurrence and mortality rate.

9/21. cauda equina syndrome in patients with low lumbar fractures.

    OBJECT: Symptoms of cauda equina syndrome (CES) can include low-back pain, sciatica, lower-extremity weakness, sensory deficit, perineal hypesthesia or anesthesia, and loss of bowel or bladder function. Several causes of the syndrome are recognized, but its optimal treatment remains controversial and has been broadly based on data gathered from series involving herniated discs. Information on the treatment of CES caused by low lumbar traumatic injuries has not been well documented. methods: Between January 2000 and December 2003, 17 consecutive cases of CES caused by low lumbar traumatic injuries at L2-5 were identified. The traumatic injuries consisted of gun shot wound in two cases, motor vehicle accident in 11, and a fall from height in four. Conus medullaris injuries causing CES were excluded from this review. Presenting symptoms, mechanisms of injury, radiographic images, timing of surgery, surgical approaches, and neurological status at the final follow up were documented. All patients underwent follow up of at least 12 months. Fourteen of 17 patients had satisfactory outcomes. Despite undergoing surgery within the first 24 hours postinjury, three patients had what was classified as a poor outcome given their residual deficits and included two cases with gunshot injuries. Recovery of leg weakness occurred within 4 months, whereas bladder and bowel function recovered within 3 months. All patients in this series underwent decompression within less than 48 hours after syndrome onset. overall, the authors found no difference regarding timing of surgery between patients in the satisfactory outcome group and those in the poor outcome group. CONCLUSIONS: Based on the evidence in this study, the severity of a patient's condition on initial presentation is the most crucial factor in predicting outcome following CES due to low lumbar injuries. Although the matter of the timing of surgery remains controversial, the authors of this study recommend that surgery be performed within 48 hours of syndrome onset.

10/21. Facet joint cysts causing cauda equina compression.

    Facet joint cysts are commonest at the L4-L5 level and are associated with facet joint degeneration and type III (degenerative) spondylolisthesis. It is extremely rare for facet joint cysts to cause symptomatic cauda equina compression. Three elderly patients presented to us with significant cauda equina compression caused by facet joint cysts. One presented with classic symptoms and signs of a cauda equina syndrome, a second with bilateral lower limb neurologic loss associated with uncontrolled epilepsy, and the third with bilateral leg symptoms as well as an upper limb tremor and fasciculation. The diagnosis was easily made after magnetic resonance scanning in two patients, although in one patient, it was significantly delayed because of his confounding neurologic picture. Lumbar spine surgery (decompression and cyst resection) was successful in resolving symptoms in all three, even though two patients had significant neurologic compromise before surgery. The occurrence of facet joint cysts in older patients can be associated with other degenerative neurologic conditions, and the diagnosis might not be apparent early. We suggest that in older patients who have a mixed picture of central and peripheral neurologic compromise, this diagnosis should be considered and investigation of the whole of the spine, not just the brain and spinal cord, should be undertaken.
