1/57. 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.

2/57. Atypical infective endocarditis.

    BACKGROUND: Although infective endocarditis has changed in the recent past as a result of microbiologic and risk factors, it continues to be clinically challenging. The disease is characterized by the formation of septic masses of platelets on the surfaces of heart valves. Several mechanisms can cause or contribute to the development of endocarditis. Although risk factors for infective endocarditis are well known, patients with atypical signs and symptoms continue to challenge us. methods: We describe a case report of a patient admitted to our inpatient service with back pain and presumed pyelonephritis. A medline literature search was conducted, using the key words "endocarditis," "back pain," and "bacterial," for the years 1986 to the present. RESULTS AND CONCLUSIONS: A 42-year-old woman with a history of intravenous drug abuse was admitted to the family practice service with back pain and pyelonephritis. She developed hypoxia and a new heart murmur and had continued fevers. blood cultures drawn in the emergency department grew methicillin-resistant staphylococcus aureus. A bone scan and magnetic resonance imaging led to the diagnosis of epidural abscess. What appeared to be a simple case of pyelonephritis with back pain became a case of infective endocarditis complicated by an epidural abscess.

3/57. epidural abscess in an obstetric patient.

    epidural abscess is a rare complication of epidural block and occasionally presents in the post partum period. A case is described where a thoracolumbar abscess presented with backache and headache 10 days after an apparently uneventful block for labour and caesarean section. The abscess was treated medically with a satisfactory outcome. The literature is reviewed in order to assess several recent reports of infectious complications of epidural block in obstetric patients.

4/57. Aggressive thoracic actinomycosis complicated by vertebral osteomyelitis and epidural abscess leading to spinal cord compression.

    STUDY DESIGN: Report of a successfully diagnosed and treated case of spinal cord compression due to epidural actinomycosis. OBJECTIVE: To illustrate that proper use of imaging strategy can greatly facilitate diagnosis and management of this rare condition. SUMMARY OF BACKGROUND DATA: Spinal actinomycosis causing epidural abscess and significant spinal cord compression is an uncommon condition. Although diagnosis is difficult, favorable results are widely reported when specific therapy is instituted. methods: A 32-year-old Chinese man had extensive dorsal thoracic soft tissue swelling and lower limb weakness. Collapse of the T5 vertebral body was found on plain radiographs with mediastinal infiltrates on chest radiograph. It took magnetic resonance imaging (MRI) to fully delineate the epidural abscess and dorsal muscular abscesses, which were not depicted by computed tomographic (CT) scan. diagnosis was made by examination of CT-guided aspirate and tissue recovered during surgery by a microbiologist. The patient received high-dose intravenous penicillin and prompt spinal decompression once diagnosis of actinomycosis was confirmed. RESULTS: The dorsal muscular abscesses and upper thoracic epidural abscess resolved rapidly after intravenous antibiotics and surgical drainage. This was well documented by follow-up MRI and the full recovery of motor power and lower limb sensation in the patient. CONCLUSIONS: High clinical suspicion and proper use of imaging data led to timely diagnosis of this rare case of mediastinal, epidural, and intramuscular thoracic actinomycosis. Specific antibiotic therapy and timely, well-targeted surgical intervention greatly improve the outcome of this condition.

5/57. Enlargement of a chronic aseptic lumbar epidural abscess by intraspinal injections--a rare cause of progressive paraparesis.

    The frequent use of invasive procedures at the spinal cord such as epidural injections has led to an increased incidence of iatrogenic abscesses. We report the case of a patient who suffered from low back pain. During epidural lumbar injections of steroids the patient developed severe radicular symptoms, resulting in severe paraparesis. We demonstrate the rare cause of this progressive deterioration, being a combination of a preexisting chronic aseptic epidural abscess and an iatrogenic enlargement by repeated epidural injections. MR-Scans demonstrated a mass lesion at the L4/5 vertebral level, which was surgically removed. Histological evaluation revealed the presence of a chronic aseptic spinal epidural abscess with acute bleedings. histology and MR-Data disclosed multiple deposits of the applied drug within the abscess and in the surrounding paravertebral soft tissue. The authors prove that the cause of the neurological deterioration was due to epidural injections into a preexisting lumbar chronic aseptic epidural abscess. Harmful and unpleasant complications may occur following epidural injections. Though we present a very rare cause of such complications, a careful monitoring of the neurological status of the patient is necessary as well as the early application of MR imaging in the case of deterioration.

6/57. Acute neurologic deterioration following lumbar puncture in an epidural abscess occurring 14 months after epidural catheter placement.

    We report the case of a 19-year-old girl admitted to the hospital with a 2-month history of back pain and a 1-week history of severe weakness, who underwent a diagnostic lumbar puncture which was swiftly followed by acute neurologic deterioration requiring ventilation. She was subsequently shown to have an epidural abscess extending from the second cervical to the fifth lumbar vertebrae. She had received uneventful epidural analgesia for childbirth 14 months previously. The case is unusual in both the acute deterioration following lumbar puncture, and also in the length of time from epidural siting to abscess formation, if this were indeed the source of the infection.

7/57. Inappropriate medical management of spinal epidural abscess.

    A 67 year old man with longstanding rheumatoid disease was referred to the regional spinal surgery unit with acute onset of paraparesis due to an extensive spinal epidural abscess of the lumbar spine. Ten months previously, he had started antibiotic treatment at another hospital for an epidural abscess arising at the level of the L2-3 disc space. Despite completing seven months of medical treatment with appropriate antibiotics, he had a recrudescence of acute back pain shortly after restarting methotrexate treatment. Urgent anterior spinal decompression with excision of the necrotic vertebral bodies of L1-3 was performed. The indications for the surgical management of spinal epidural abscess are reviewed.

8/57. Septic arthritis of a lumbar facet joint due to pyonex.

    We present a case of septic arthritis of a lumbar facet joint with an associated epidural abscess. A 13-year-old boy was hospitalized with acute severe back pain and fever after pyonex was done. The infection was precisely localized with magnetic resonance imaging, bone and gallium scintigraphy. He responded to antibiotic therapy. We suppose that the infection was caused by pyonex because the blood cultures were negative, and the patient had an abrupt onset of severe pain and fever 24 h after the acupuncture.

9/57. Case report: catheter-related epidural abscess.

    INTRODUCTION: Catheter-related spinal epidural abscesses are rare but increasing in incidence. CLINICAL PICTURE: An elderly gentleman received 4 days of continuous epidural analgesia following multiple traumatic rib fractures. Five days subsequently, he developed an extensive epidural abscess accompanied by backache, lower limb weakness, fever, leukocytosis and Staphylococcal bacteraemia. TREATMENT: He received appropriate intravenous antibiotics and underwent an emergent decompressive laminectomy. OUTCOME: A good outcome was achieved because of prompt diagnosis, appropriate intravenous antibiotics and timely surgical intervention. CONCLUSIONS: It is important to be vigilant and continue to maintain good clinical practice and a high index of suspicion for this procedural-related complication.

10/57. Hematogenous pyogenic facet joint infection of the subaxial cervical spine. A report of two cases and review of the literature.

    Two cases of hematogenous, pyogenic, subaxial cervical facet joint infection are reported, and the literature is reviewed. infection of the cervical facet joint is a rarely diagnosed condition; only one case has been reported in the literature. Lumbar facet joint infections are also rare but more commonly reported. Approximately one fourth of facet joint infections in the lumbar spine are complicated by epidural abscess formation, which can lead to a neurological deficit. Because of the paucity of reports on cervical facet joint infections, the clinical characteristics of this entity are not well known. Both patients presented with an acute onset of unilateral neck pain that radiated into the ipsilateral shoulder. Frank radicular pain was initially absent. Unilateral upper-extremity motor weakness that was attributed to associated epidural abscess or granulation tissue formation was also demonstrated in both patients. leukocyte count and erythrocyte sedimentation rate were elevated in both cases. magnetic resonance imaging was necessary to obtain an accurate diagnosis. Staphylococcus aureus was identified as the offending pathogen in both cases. Decompressive surgery and antibiotic therapy were required to cure the condition. One patient recovered completely and the other sustained a permanent motor deficit. Hematogenous cervical facet joint infection is a rare clinical entity that has many characteristics in common with the more-common lumbar homolog. All three reported cases, however, have been complicated by epidural abscess or granulation tissue formation that has led to a neurological deficit. This finding suggests that a facet joint infection in the cervical spine may have a less benign clinical course than that in the lumbar spine.
