ABSTRACT

Spinal subdural abscesses (SSA) are very rare disease. The etiologies of SSA are hematogenous spread, iatrogenic contamination, and local extension. Elevated WBC counts, ESR, and C-reactive protein are usually found in laboratory tests. But they are not sensitive indicators of SSA, especially chronic abscesses patient tend to have a less specific characteristic. We report the case of a healthy man with chronic subdural abscess referred to our hospital as an intradural-extramedullary (IDEM) tumor. The patient presented with voiding difficulty and pain in the back and left leg. In a contrast MRI scan, a rim-enhanced mass-like lesion was seen at the L5/S1 level. But adjacent ill-defined epidural fat enhancement that are unusual imaging manifestation for IDEM tumors was seen. He had no fever and normal WBC, ESR, and CRP. In addition, the patient had no previous infection history or other disease, but he did have an epidural block for back pain at another hospital 2 years previously. So, we repeated the MRI with a high-resolution 3-T scanner. The newly taken MR images in our hospital revealed a clear enlargement of lesion size compared to the previous MRI taken 1 week before in other hospital. We suspected a chronic spinal subdural abscess with recent aggravation and immediately performed surgical evacuation. In the surgical field, tensed dura was observed and pus was identified after opening the abscess capsule. Because chronic spinal subdural abscesses are difficult to diagnose, we could differentiate with IDEM tumor exactly and an exact history taking, contrast MRI are required.

ABSTRACT

STUDY DESIGN: Case report and review of relevant literature. OBJECTIVE: To report a rare case of a thoracolumbosacral spinal subdural abscess (SSA) and highlight the magnetic resonance imaging (MRI) appearance and surgical management. SUMMARY OF BACKGROUND DATA: SSA is rare, as most intraspinal abscesses are epidural in location. Extensive thoracolumbosacral SSA has only rarely been reported. The MRI features and options for limited surgical management are not well described. METHODS: A case report of SSA is presented and relevant literature is reviewed. RESULTS: An elderly female presented with worsening back pain and sepsis. MRI demonstrated an extensive intraspinal abscess, extending from the upper thoracic spine to the sacrum. Both axial and sagittal images demonstrated a subdural location of the collection, with preservation of the dorsal epidural fat and mass effect on the spinal cord. Cord compression was most marked at the T8 level. Limited midthoracic laminectomies were performed. The epidural space seemed normal intraoperatively. A limited longitudinal durotomy yielded purulent fluid. After intraoperative irrigation, primary dural repair was performed. At 2-year follow-up, the patient had no clinical, radiographical, or laboratory evidence of residual or recurrent spinal infection. CONCLUSION: Careful review of MRI can localize an intraspinal abscess to the subdural space. Even for extensive subdural collections, limited operative management can achieve excellent clinical outcome. LEVEL OF EVIDENCE: N/A.

ABSTRACT

INTRODUCTION: Positioned anatomically between the spinal epidural space and the intramedullary compartment, the spinal subdural space remains the least common area of localized infection in the central nervous system. Infectious processes of the subdural spinal space include subdural spinal empyema, subdural spinal abscess, infected spinal subdural cyst, and infectious spinal subdural cyst. To date, there has been no systematic review of these entities in children, with the cumulative knowledge of the pathophysiologic, microbiologic, and demographic characteristics of these infections relegated solely to few small series and case reports. METHODS: A series of 11 recent cases culled from the collaboration of international authors are presented. In addition, an exhaustive MEDLINE search and manual review of the international literature was performed, identifying a total of 73 cases of spinal subdural infections in patients under the age of 21. Data of interest include the age, sex, signs, and symptoms at presentation, spinal location of infection, presence of spinal dysraphism, and other comorbidities, offending organism, treatment, outcome, and follow-up. RESULTS: Patients ages ranged from 4 weeks to 20 years (mean, 6.5 years). Males outnumbered females by a ratio of 2:1. Over half (53 %) of spinal subdural infections in children were associated with spinal dysraphism or other congenital abnormalities of the spine. The commonest organism to infect the spinal subdural space in children is mycobacterium tuberculosis and the thoracic spinal region was most commonly infected. CONCLUSIONS: The disease is usually treated surgically, although a more expectant approach consisting of antibiotics and observation has also been proposed.

ABSTRACT

OBJECT: Parafalcine subdural empyema and those along the superior and inferior surface of the tentorium are rare entities. We present a series of 10 patients where we have attempted to describe the pathophysiology, clinical features, and management of subdural empyema. METHODS: The study group included 10 cases of falcotentorial subdural empyemas managed between 2004 and 2010. The mean age group was 14.4 years. Seven patients had empyema along the falx or superior surface of tent, and the remaining three had empyema along the inferior surface of tent. Fever, raised intracranial pressure symptoms, falx syndrome, and seizures were the usual presenting features. These patients had an indolent presentation as compared to convexity subdural empyemas. The diagnosis was made based on radiology. Chronic suppurative otitis media was a causative factor in five patients; in the remaining patients, the source was ascribed to be hematogenous. All patients were treated with antibiotic therapy (6 weeks) ± surgery. Two patients were treated conservatively, and the remaining eight patients underwent definitive surgery in the form of craniotomy (supratentorial)/craniectomy (infratentorial) and evacuation of pus. The pus was limited within two leaves, one adherent to the falx/tent and the other one to the pia-arachnoid of adjacent parenchyma. The wall along the falx or tent could be peeled off easily and was excised in all cases to lay open the cavity widely. The wall along pia-arachnoid was left as it is. Pus culture was positive in four and blood culture positive in two cases. There was only a single mortality in our series. The outcome was assessed by the Glasgow Outcome Scale. The mean duration of follow-up was for 18.8 months, and all patients who survived had a good outcome. CONCLUSION: Falcotentorial empyema remains a rare entity. The presentation is indolent as compared to convexity subdural empyemas, possibly due to its limitation secondary to arachnoid adhesions at the junction of falx, tent, and convexity dura. The main stay of management remains craniotomy, evacuation, and partial excision of the wall, laying it completely open, unless it is extremely thin. With appropriate surgery and antibiotic therapy, a good outcome can be expected.

ABSTRACT

Spinal sepsis (spinal epidural or subdural abscess) is a rare condition, which, if not diagnosed rapidly, can lead to paralysis or death. It is difficult to diagnose in its early stages as the symptoms are as yet non-specific. We aimed to identify predisposing factors and presenting symptoms that might aid in the early diagnosis of spinal sepsis. A case-control study was performed with non-pediatric patients who had been diagnosed with spinal sepsis from 1998 to 2007. Our control group comprised 80 randomly selected patients who had presented to the emergency department with back pain. We identified 72 patients with spinal sepsis. A multivariate analysis revealed that obesity (adjusted odds ratio [aOR] 21.4; 95% confidence interval [CI] 1.8-257.5) and alcoholism (aOR 6.5; 95% CI 1.3-32.8) were important predictive factors for spinal sepsis. To our knowledge, this is the first report that associates obesity and alcoholism with spinal sepsis.

ABSTRACT

STUDY DESIGN: We retrospectively analyzed spinal infection (SpI), in a teaching Hospital, in Central Greece. OBJECTIVE: To study presentation, etiology, and outcome of SpI in Central Greece. SUMMARY OF BACKGROUND DATA: SpI most frequently involves the intervertebral disc and adjacent vertebral bodies and can cause neurologic impairment. METHODS: Thirty three patients (23 men; age [mean +/- standard deviation], 60.6 +/- 11.3 years; disease duration, 44.5 [+/-54.7] days) hospitalized with SpI between January 2000 and December 2007 were included in the study. All patients had magnetic resonance imaging of the spine. RESULTS: Nineteen patients had pyogenic SpI (57.6%) and 14 patients had granulomatous SpI, 11 due to Brucella spp (34.4%), 3 due to Mycobacterium tuberculosis (9.4%). Staphylococcus aureus was the most frequent cause of pyogenic SpI, and spondylodiscitis (SpD) was the most frequent localization. Epidural entension was found in 8 of 17 pyogenic SpD and in 2 of 11 brucellar SpD patients. Subdural extension was detected in 3 patients with pyogenic SpD. Blood cultures were positive in 17 of 19 patients with pyogenic SpI. Two patients had concomitant endocarditis (staphylococcal 1, enterococcal 1). The most common associated disease was diabetes mellitus. All but 2 patients received medical treatment alone. Two patients died of uncontrollable sepsis. CONCLUSION: Back pain in presence of fever, constitutional symptoms, and/or high inflammation markers should alert physicians for spinal infection. In endemic areas, Brucella is a frequent cause of SpI.

ABSTRACT

BACKGROUND: Infratentorial empyema is an uncommon complication of bacterial meningitis. Very little is known about its recognition and appropriate management. METHOD: We present a patient with infratentorial subdural empyema and compare findings with 41 cases with infratentorial empyema reported in the literature. RESULTS: Many patients with infratentorial empyema presented as subacute meningitis with neck stiffness and decreased consciousness. Diagnosis was often delayed. The minority had cerebellar findings and cranial nerve deficits. Clues to the diagnosis were presence of otitis, sinusitis, or mastoiditis and recent surgery for these disorders. The majority of patients underwent craniotomy; conservative treatment with antibiotics was associated with relapse of symptoms. The mortality rate was high especially in those with subdural empyema. CT failed to clearly visualize infratentorial subdural empyema in several reported cases. CONCLUSIONS: Infratentorial empyema is a life-threatening rare complication of bacterial meningitis. MRI, including diffusion-weighted imaging, is the preferred imaging technique in patients with suspected or proven bacterial meningitis and associated ear-nose-throat infection with deterioration in consciousness and neurologic signs that suggest a posterior fossa lesion. Neurosurgery should be regarded as first choice therapy.

ABSTRACT

Papilledema is an uncommon presentation of spinal cord processes. Spinal subdural abscess (SSA) is a rare site of post-operative infection. We report a patient who developed papilledema as the primary manifestation of a post-operative lumbar subdural abscess. A spinal abscess should be considered in the post-operative spinal surgery patient who develops papilledema in the setting of persistent back pain. The increased intracranial pressure associated with lumbar spinal cord abscess most likely results from a markedly elevated cerebrospinal fluid (CSF) protein or the disruption of CSF flow in the spinal cul-de-sac.

ABSTRACT

A 71-year-old man developed a large multi-loculated subdural empyema following the evacuation of a chronic subdural haematoma. The pockets of pus were successfully evacuated endoscopically via the burr holes resulting in good recovery and no re-accumulation. The advantages of this technique and the difficulties encountered during this procedure are discussed.

ABSTRACT

Subdural empyema is an intracranial infection that has remained difficult to diagnose and to treat. Seventeen patients with this infection, treated between 1967 and 1974, are analyzed and compared to published series with particular regard to diagnosis using newer procedures and treatment, considering the primary focus of infection. The infection is usually located in the supratentorial spaces, is often bilateral, and results most often from para-nasal sinusitis (single most common cause), otitis, neurosurgical operative infections, and meningitis in infants. Patients suffering from subdural empyema generally present with rapid onset of depressed sensorium, seizures, focal neurological deficits, and signs of increased intracranial pressure, following a period of days to weeks characterized by headache and fever. All 17 of our patients demonstrated localizing neurological signs and 16 manifested either fever or leukocytosis. Diagnostic studies, except for cerebral arteriography, do not reliably corroborate or exclude the diagnosis. Cerebral arteriography established the diagnosis and defined the location and extent of the empyema in all of our cases. The EEG and brain scan produced frequent false-negative and/or non-localizing results in 10 and 8 patients, respectively. The cerebrospinal fluid was abnormal from all 15 patients examined by lumbar puncture, but the findings were similar to those in other infectious and non-infectious central nervous system diseases. Signs of transtentorial herniation developed within eight hours following lumbar puncture in three of seven patients who had exhibited signs of increased intracranial pressure before the procedure was performed. Bacterial cultures were positive in 13 of our cases. A review of our data and that of other studies indicates that the organisms associated with subdural empyema are consistent with those expected from infections of the primary site; e.g. sinusitis, otitis, meningitis, site of prior neurosurgery. A therapeutic approach is suggested which emphasizes specific antibiotic regimens appropriate to the primary site of infection and prompt neurosurgical intervention with evacuation of the subdural spaces bilaterally. In general, combination antimicrobial therapy employing high parenteral doses of penicillin G, a semi-synthetic penicillinase-resistant penicillin and chloramphenicol is recommended.

ABSTRACT

Anaerobic bacteria were isolated from the subdural space in all four cases of subdural empyema encountered over a 2 and a half year period. Only one aerobe was isolated in these cases. The bacteriology of subdural empyema was further analyzed from a review of 327 cases reported in the English literature. Anaerobes accounted for 12 per cent of 234 cases; In addition, 27 per cent of cases were reportedly "sterile." These data support our finding that anaerobic bacteria may play a far more important role in subdural empyema than was previously appreciated.
