1/44. Vascular changes in tuberculous meningoencephalitis.Our report refers two cases of tuberculous encephalomeningitis which differ in the course and pathological changes. In case 1 blood vessels showed features of peri, endo-, or panvasculites. In some vessels endothelium proliferation leading to the stenosis or obliteration of the vascular lumen was observed. necrosis was an effect of vessels occlusion. In case 2 many fewer vessel were involved in onflammation process. Vascular changes were also less extensive and were observed more rarely. Tuberculous infection often caused less tissue lesions than vascular changes. Different pathological changes probably depend on the type and virulence of Myobacterium tuberculosis and on the host immune response to the infection.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
2/44. enterobacter sakazakii brain abscess in the neonate: the importance of neuroradiologic imaging.BACKGROUND: enterobacter sakazakii is a rare but important cause of life-threatening neonatal sepsis and meningitis complicated by the development of brain abscess. OBJECTIVE: Given the neurotropic qualities of this organism, early diagnosis and treatment are crucial as a poor prognosis follows brain abscess formation. MATERIALS AND methods: Cross-sectional imaging (CT and MRI) play an important role in the diagnostic work-up. CONCLUSION: A biopsy-proven case of E. sakazakii brain abscess, which was diagnosed on MR images, is presented, and the importance of prompt radiologic imaging of the central nervous system in the work-up of patients with this life-threatening disease is discussed.- - - - - - - - - - ranking = 2keywords = life (Clic here for more details about this article) |
3/44. Otogenic brain abscess--a case report.brain abscess is one of the life-threatening complications of otitis media. mortality and morbidity have decreased with the advent of antibiotic therapy. More frequently encountered in cases of acute otitis media in the preantibiotic era, in recent years otogenic brain abscess was noticed almost only in patients of chronic otitis media with cholesteatoma. A case of brain abscess in a 49-year-old female was initially diagnosed as a headache. A high resolution computed tomography (HRCT) scan of the temporal bones later revealed that there were two abscesses over the right side temporal lobe. A modified radical mastoidectomy was performed. Cultures of the middle ear cholesteatoma later grew pseudomonas aeruginosa and Strenotrophomonas maltophilia. Antibiotic therapy was carried on for three months postoperatively. The patient improved but retained a conductive hearing loss.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
4/44. Quantitative proton magnetic resonance spectroscopy of focal brain lesions.The diagnostic value of single-voxel proton magnetic resonance spectroscopy (2 T, stimulated echo acquisition mode, TR = 6,000 ms, TE = 20 ms, 4-5 mL volumes-of-interest) was assessed for a differentiation of focal brain lesions of unknown etiology in 17 patients 1-14 years of age. Absolute metabolite concentrations were compared with age-matched control subjects and an individual control region. Most of the brain tumors were characterized by strongly reduced total N-acetylaspartyl compounds and marked increases of myo-inositol and choline-containing compounds, consistent with a lack of neuroaxonal tissue and a proliferation of glial cells. Lactate was elevated in only four patients. When using this pattern for a metabolic discrimination of brain tumors from other focal lesions, proton spectroscopy correctly identified 14 of 17 abnormalities, as confirmed by histologic examination after neurosurgical intervention. One false-positive tumor diagnosis was a severe reactive gliosis mimicking a typical tumor spectrum. Two inconclusive cases comprised an astrocytoma with moderately elevated myo-inositol but reduced choline-containing compounds and a patient with an abscess leading to a marked reduction of all metabolites but strong contributions from mobile lipids. In summary, quantitative proton spectroscopy has considerable clinical value for preoperative characterization of focal brain lesions.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
5/44. brain abscess related to metal fragments 47 years after head injury. Case report.The authors report a case of symptomatic brain abscess in a 51-year-old man who presented with personality changes and generalized seizures. He had survived a grenade explosion injury during the korean war 47 years previously. Computerized tomography scanning revealed multiple conglomerate rim-enhancing lesions and metallic foreign bodies in the right frontal lobe. The mass was totally removed and pseudomonas aeruginosa was isolated from microbial cultures. Retained foreign bodies in the brain, whether bone or metal, should be removed at the time of injury if at all possible. If this cannot be accomplished, patients with such retained foreign bodies should be carefully monitored for life.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
6/44. brain abscess by citrobacter diversus in infancy: case report.citrobacter diversus is closely related to brain abscess in newborn infants.

7/44. Ramichloridium mackenziei brain abscess: report of two cases and review of the literature.We report two cases of brain abscesses caused by Ramichloridium mackenziei, a neurotropic dematiaceous fungus that seems to be geographically restricted to the middle east. One of the patients had chronic myelomonocytic leukemia but did not receive any chemotherapeutic agents. The other patient was a normal host. Both cases had a fatal outcome despite aggressive antifungal therapy and surgical intervention. Herein, we review all previously described cases in the literature, and discuss the epidemiology, mycology and histopathology of this life-threatening organism.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
8/44. Successful therapy combined with surgery for severe post-transplant nocardiosis.We report a case of a 35-year-old man with nocardiosis infection involving soft tissue and the central nervous system who had received a cadaveric donor kidney. The patient was admitted with fever, malaise and right shoulder pain. Soft tissue abscess was seen on ultrasound examination. It was presumed due to gram ( ) microorganisms, so 4 g day (IV) ampicillin/sulbactam was started empirically once the abscess was drained. nocardia asteroides was found in the pus specimen. On the second day in hospital, severe headache, ataxia and signs of meningeal irritation appeared. The cranial CT showed two intracranial abscesses in the frontal lobe and cerebellum. We assumed nocardia asteroides was the infective agent for the cerebral abscesses, so antibiotic therapy was switched to trimethoprim-sulphamethox-asole (3x160/800 mg/d). nausea and vomiting occurred on the fifth day of therapy, improving after drainage from the frontal abscess. However, these complaints recurred five days later. CT showed cerebellar abscess had become bigger. The patient's complaints improved after the second surgical drainage. N. asteroides was again grown in the aspiration fluids of both cerebral abscesses. Complete regression of the abscesses was seen in the CT after two months. Co-trimoxazole was continued for six months then withdrawn. Graft dysfunction was not observed. Early medical and surgical interventions may be life-saving in this potentially lethal disease.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
9/44. Intracranial abscess as a complication of subperiosteal abscess of the orbit.PURPOSE: To describe the potential complication of intracranial abscess in the setting of orbital abscess. methods: We retrospectively reviewed case reports and the literature. Three patients were found to have pansinusitis progressing to subperiosteal abscess of the orbit and subsequent intracranial abscess. RESULTS: Three patients, ages 14, 26, and 57 years, with concurrent pansinusitis, subperiosteal abscess of the orbit, and intracranial abscess were treated with intravenous antibiotics and surgical drainage of the orbital abscess and sinuses. Two of the three patients required drainage of the intracranial abscess. CONCLUSIONS: Although rare, intracranial abscess is a life-threatening complication of orbital abscess. It requires aggressive intervention by a multidisciplinary team.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
10/44. 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.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
