Neurological and behavioral sequelae in children operated on for brain abscess.

In order to characterize neurological, intellectual and behavioral sequelae better after surgical treatment of brain abscess in childhood, 32 children were studied over a 10-year time span after treatment of a brain abscess. Depending on the clinical condition, surgical treatment consisted of simple aspiration through a burr hole or of total excision after craniotomy. There were only 3 postoperative deaths (9%). The scheduled time for long-term follow-up was 3 years after surgery. The patient assessment included information concerning the presence of seizures, accurate neurological examination, an EEG, and a battery of intellectual tests to evaluate the presence of behavioral-mental deficits. Late seizures developed in 7 of the 29 survivors. Five patients presented permanent hemiparesis after surgical treatment. It is noteworthy that the intellectual impairment observed was more severe in younger patients, while the behavioral disturbances were more marked in school-age children.

Nonsurgical management of neonatal multiple brain abscesses due to Proteus mirabilis.

A newborn infant with Proteus mirabilis meningitis developed multiple brain abscesses with diameters ranging from 2 to 4 cm. Intravenous antibiotic therapy alone without surgical intervention led to the complete resolution of this complication. The case supports that this may be an acceptable treatment of multiple brain abscesses in neonates. However, the clinical outcome was relatively poor, since a porencephalic cyst, hypodense areas in CT scan, and psychomotor retardation were found at one year of age.

[Computerized tomography, radionuclide gamma-topography and angiography in the diagnosis of brain abscesses of rhinosinusogenic origin].

X-ray and other methods were used to examine 21 patients with brain abscesses of rhinosinusogenic origin. The diagnostic methods including computer tomography, brain gamma-topography and cerebral angiography yielded objective information about the localization, size, distribution and multiplicity of brain abscesses. They were displayed as doughnuts or rings on computer tomograms and as pies on gamma-topograms. The noninvasive methods such as computer tomography or gamma-topography proved very helpful for assessing the efficacy of surgical intervention at an early postoperative stage.

[Aspiration and drainage for brain abscess causing massive bleeding from abscess capsule: case report].

The authors report a rare complication during aspiration of a brain abscess. A 23 year-old man who had undergone surgery for empyema two months previously presented himself at our hospital complaining of headache, deterioration of activity and conscious level. An emergency computed tomography demonstrated a left frontal brain abscess. Aspiration and drainage were performed. However, this resulted in massive hematoma in and around the abscess capsule. Following craniotomy and excision of the abscess, the patient was cured. Microscopic examination of the abscess revealed the formation of a complete capsule consisting of fibroblasts and collagen fiber. In addition to this, significant neovascularization with inflammatory cells was apparent around the capsule. These findings suggest that profuse hemorrhage may occur in aspiration and drainage surgery.

Nocardial brain abscess: observation of treatment strategies and outcome in Switzerland from 1992 to 1999.

BACKGROUND: Brain abscesses caused by Nocardia spp. are rare, but life-threatening infections that are notoriously difficult to diagnose and treat and which occur mainly in immunocompromised patients. Standard treatment guidelines are not available. METHODS: A systematic search for nocardial brain abscesses from 1992 to 1999 was conducted in Switzerland for the comparison of clinical presentation, treatment strategies and outcome. RESULTS: Seven cases were found, for which data of six were available. In 4/6 patients antimicrobial therapy led to a decrease in the size of abscesses. Four of six patients died. The cause of death was likely due to underlying co-morbidities, rather than the nocardial infection. CONCLUSION: The finding that treatment was different in each case underscores the lack of therapeutic guidelines.

Brain abscess following transorbital penetrating injury due to bamboo fragments--case report.

A 56-year-old female presented with transorbital penetrating injury caused by bamboo fragments, which resulted in brain abscess 2 weeks after the injury. Initial computed tomography (CT) of the head did not reveal the foreign bodies. However, follow-up CT demonstrated a well-defined hyperdense abnormality of 1.0 cm length in the left orbit and brain abscess in the left temporal lobe. The lesion corresponding to the hyperdense abnormality on CT appeared isointense on T1-weighted magnetic resonance (MR) imaging and hypointense on T2-weighted MR imaging. The bamboo fragments were surgically removed, and aspiration and continuous drainage were performed for the brain abscess. The postoperative course was uneventful and the patient was transferred to a local hospital with minor neurological deficits. Bamboo foreign bodies may show changes in properties on CT and MR imaging in the subacute stage. Careful radiological examination and follow-up monitoring are required for the correct diagnosis and treatment of such injuries.

Brain abscess in children.

During that last 6 years, 100 children have been treated for brain abscess at the National Institute of Mental Health and Neurosciences (NIMHANS), Bangalore. Of these, 69 abscesses were otogenic. The treatment included aspiration of the abscess (84% of cases) and antibiotic therapy. CT scan as a diagnostic tool was available only for a few cases in the last year. In 16% of the cases the abscess was excised. The overall mortality was 21%. Of the surviving children, 76% recovered totally. Epilepsy as a sequel occurred in 21% of the cases. The fact that mortality continues to be high is attributed to the degree of impairment of consciousness of the children at the time of admission. Early detection and successful treatment of brain abscess in children still remain a clinical challenge.

Gemella morbillorum deep brain abscess successfully treated with combined stereotactic, medical, and imaging approach.

A rare case of brain abscess due to Gemella morbillorum, a normal inhabitant of the oral cavity, is presented. The aim of this report is to draw the attention of radiology literature readers to this little known pathogen, which caused a potentially life-threatening condition in an immunocompetent young man, and to emphasise the usefulness of a combined stereotactic, medical, and imaging approach to deep-located brain abscesses.

[Brain abscess developed five years after splenectomy in a patient with idiopathic thrombocytopenic purpura].

The increased susceptibility to infection following splenectomy has been well documented. We report here, a case of brain abscess developed five years after splenectomy in a patient with idiopathic thrombocytopenic purpura (ITP). A 65-year-old woman was admitted to our hospital because of fever, mental disorientation, and weakness in August, 1999. She had been followed with diagnoses of essential hypertension and type 2 diabetes mellitus (DM) since 1988. The patient was diagnosed as having ITP in 1992, and then underwent splenectomy in 1994. Monoclonal gammopathy of undetermined significance (MGUS) of IgG, lambda type was found in February 1999. Though high grade fever persisted after admission, blood cultures were negative. Antibiotics were given without a satisfactory effect. Right hemiparesis and worsening of consciousness developed subsequently. Contrast enhanced cranial computed tomography (CT) disclosed a ringed enhanced low density mass in the left parieto-occipital lobe compatible with a diagnosis of brain abscess. Surgical drainage was performed and 20 ml of pus was obtained. No primary infectious focus of the brain abscess was detected with intensive examinations.

[Experiences with oto-rhinogenous brain abscesses (author's transl)].

The results and conclusions of 43 surgical interventions performed on account of oto-rhinogenous brain abscess are reported. In these patients the infection of brain substance occurred in two ways: 1 by contact propagation and 2. per venous reflux, associated with thrombosinusitis. In the 1. the brain abscess was accompanied by purulent meningitis and the majority of the patients died during the postoperative period. In the 2, the patients operated on account of cerebral abscess developed per venous reflux, improved and became health. In order to get more exact localisation of the abscess there are different radiological auxiliary methods available: in supratentorial abscesses exact informations can be obtained by carotid angiography, while in the cases of infratentorial abscesses the pneumography is helpful, notwithstanding the latter is not fully harmless. As the ideal operative solution the total exstirpation of the abscess with undamaged capsule can be proposed.

Bilophila wadsworthiain brain abscess: case report.

A case of a patient with a 20-year history of chronic otitis media complicated by cholesteatoma and brain abscess is described. A CT scan with contrast material showed three abscess cavities in the right cerebellar hemisphere. A culture from a specimen of the cholesteatoma yielded a significant amount of growth of Bilophila wadsworthia, Bacteroides fragilis and Prevotella oris and a moderate growth of alpha-streptococci and Staphylococcus simulans. From the pus of the brain abscess we also isolated numerous Bilophila wadsworthia, Bacteroides fragilis and Prevotella oris and some Prevotella buccae and Peptostreptococcus anaerobius. No aerobes were present. The patient underwent a craniotomy and the biggest abscess was removed together with the capsule. The antimicrobial therapy included penicillin plus metronidazole and later augmentin. The result of the treatment was a complete cure and total recovery of the patient. This is the first documentation of isolation of B. wadsworthia in chronic otitis media and in brain abscess.

Discordance between F-18 fluorodeoxyglucose uptake and contrast enhancement in a brain abscess.

A 29-year-old human immunodeficiency virus-negative intravenous drug abuser with a right hemispheric staphylococcal brain abscess underwent PET imaging of 18F-fluorodeoxyglucose (FDG) brain uptake. Diffuse right cortical hypometabolism was noted, as well as crossed cerebellar diaschisis. Unlike previous PET findings on FDG uptake in a brain abscess, however, the most intense uptake of FDG was found within the abscess and not in the contrast-enhancing walls.

Brain abscess due to Gordona terrae in an immunocompromised child: case report and review of infections caused by G. terrae.

A brain abscess complicated antineoplastic chemotherapy for a primary cerebral rhabdoid tumor in an immunocompromised boy. Culture of purulent exudate obtained by surgical puncture of an intracranial hematoma yielded a gram-positive microorganism initially identified as a Rhodococcus species by conventional biochemical analysis; however, the isolate was subsequently identified as Gordona terrae by ribosomal DNA analysis. To our knowledge, this is the third case of human infection caused by G. terrae and the first case of a brain abscess due to this organism. As this case demonstrates, this species may cause opportunistic invasive infection in severely immunocompromised patients. The identity of clinical isolates believed to be G. terrae should be confirmed by molecular methods until better species-specific phenotypic markers become available.

Sonographic detection of multiple brain abscesses in a newborn with IgA deficiency.

We report the case of a neonate with selective IgA deficiency and multiple brain abscesses diagnosed with sonography. Brain sonography revealed multiple abscesses in the left hemisphere; the abscesses ranged from 10 to 20 mm. Cultures obtained from the cerebrospinal fluid and blood were positive for Proteus mirabilis. The neonate responded promptly to broad-spectrum antibiotic therapy and had no neurologic sequelae. Because IgA deficiency is associated with infections, we believe it was a predisposing factor for the brain abscesses.

Brain abscess caused by Streptococcus intermedius: two case reports.

BACKGROUND: Although Streptococcus intermedius has been recognized as an important pathogen for abscess formation outside the central nervous System, the Streptococcus milleri group, of which it is a member, has not been recognized as a specific pathogen for brain abscess, often thought to be caused by Streptococcus viridans, which includes other streptococcal species. CASE DESCRIPTION: Two cases of brain abscess in the left frontal lobe caused by S. intermedius, which responded well to antimicrobial treatment combined with needle aspiration, are presented. In the first patient, the predisposing disease was paranasal sinusitis of the frontal and ethmoid sinuses. In the second patient, the source of the pathogen was not detected despite extensive examination. The patients underwent aspiration of pus under ultrasound guidance in the first patient, and via a computed tomography-guided stereotactic procedure in the second patient. They subsequently received appropriate antimicrobial therapy against S. intermedius isolated from the pus culture. Both patients were discharged without any neurological deficits. CONCLUSION: It is important to recognize S. intermedius as a pathogen of brain abscess, and to be aware of its predisposing factors, i.e., mucosal disturbance and liver abscess.
