11/897. Respiratory foreign bodies and eikenella corrodens brain abscess in two children.We report the coexistence of aspirated foreign bodies and brain abscess in two boys. One child had aspirated a metallic needle, and in the other boy partially embedded sunflower seeds were found in the bronchial wall. Both patients had growth of eikenella corrodens (oral gram-negative flora) from the abscess. Aspirated foreign body in the respiratory tract should be one of the diagnostic considerations if any of the normal oropharyngeal organisms such as E. corrodens is the causative organism of brain abscess.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
12/897. Nocardial infection in a renal transplant recipient on tacrolimus and mycophenolate mofetil.Infection with nocardia spp. is an uncommon but important cause of morbidity and mortality in organ transplant recipients. Cotrimoxazole prophylaxis against urinary tract infection and pneumocystis carinii pneumonia in these patients usually prevents nocardial infection also. We report the case of a patient on tacrolimus and mycophenolate mofetil who developed drug-induced diabetes mellitus followed by nocardial brain infection. This infection occurred despite conventional cotrimoxazole prophylaxis. physicians should be aware that newer, more potent and more diabetogenic immunosuppressive regimens may increase the risk of opportunistic infections such as nocardiosis, even in the presence of "adequate" antimicrobial preventive measures.- - - - - - - - - - ranking = 0.16666666666667keywords = brain (Clic here for more details about this article) |
13/897. In vivo proton MR spectroscopy of untreated and treated brain abscesses.MR spectroscopy was performed in three patients with brain abscesses. In two patients, MR spectroscopy revealed end-products of bacterial breakdown (acetate, succinate, amino acids, lactate) in the abscess cysts. In one of these, the spectrum was reversed to a single lactate peak after treatment. In the third patient, MR spectroscopy was performed only after treatment and showed a single nonspecific lactate peak. MR spectroscopy is a potential tool for noninvasive diagnosis of brain abscess and might be useful for evaluating changes after treatment.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
14/897. Group A streptococcal brain abscess.A 48-y-old woman with an acute Group A streptococcal brain abscess is described. The abscess enlarged rapidly with neurological deterioration and required open drainage and excision. The patient was treated with antibiotics for 6 weeks and recovered completely. Group A streptococcus is a rare cause of brain abscess in the antibiotic era and may require urgent neurosurgical intervention.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
15/897. Use of diffusion-weighted MR imaging in differential diagnosis between intracerebral necrotic tumors and cerebral abscesses.The differential diagnosis between intracerebral necrotic tumors and cerebral abscesses is frequently impossible with conventional MR imaging. We report two cases of cerebral abscesses that showed high signal on diffusion-weighted echo planar imaging and a strongly reduced apparent diffusion coefficient. This appearance was not present in our cases of necrotic/cystic gliomas (eight cases) and necrotic metastases (two cases). We believe that diffusion-weighted MR imaging may be a diagnostic clue in cases of cerebral "ring-enhancing" masses.- - - - - - - - - - ranking = 0.83668601309628keywords = cerebral, intracerebral (Clic here for more details about this article) |
16/897. neuroimaging findings of the development and resolution of solitary brainstem abscess: characteristics of neuroimagings in the early stage of brainstem abscess and importance of surgical management for brainstem abscess--case report.A 64-year-old female presented with a solitary brainstem abscess. magnetic resonance imaging and computed tomography demonstrated the development and resolution of the brainstem abscess with an unusual and fluctuating clinical course over several months. Serial neuroimaging examinations are required to detect a brainstem abscess in the early stage to establish the optimum treatment.- - - - - - - - - - ranking = 2.5keywords = brain (Clic here for more details about this article) |
17/897. Fungus-like hyphochytrids associated with human disease.We report two cases, with liver and brain abscess, respectively, where fungus-like organisms belonging to the Hyphochytriomycota were found at the site of inflammation together with peptococcus in the first and cysticercus cellulosae in the second case. This is the first time these groups of organisms have been reported in human material. The role of hyphochytrids in human pathology remained uncertain as they were found together with already known human pathogens.- - - - - - - - - - ranking = 0.16666666666667keywords = brain (Clic here for more details about this article) |
18/897. Successful treatment of cerebral aspergillosis with a high oral dose of itraconazole after excisional surgery.We report a case of cerebral aspergillosis which originated from the sphenoid sinus, and involved a progressive decrease of visual acuity. The neurological signs indicated a cavernous sinus invasion. After extensive intracranial surgery we treated the residual aspergillosis with a high oral dose of itraconazole (800 mg/d for 4 months, followed by 400 mg/d for 5 months). The neurological impairments of the patient gradually subsided with the resolution of the fungal lesion shown on MRI. The successful therapy indicated that itraconazole has a significant role in the treatment of advanced cerebral aspergillosis if it is used in high doses (16 mg/kg/d for adults).- - - - - - - - - - ranking = 0.37571136497344keywords = cerebral (Clic here for more details about this article) |
19/897. Brain abscesses associated with pulmonary arteriovenous malformations.We present three patients with brain abscesses who also had pulmonary arteriovenous malformations (AVMs). All patients had hereditary haemorrhagic telangiectasia (Osler's disease). It is probable that the lung AVMs contributed to the development of the brain abscesses by allowing bacteria easier access to the systemic circulation through a right to left pulmonary vascular shunt, bypassing the filtering action of the pulmonary capillaries. In addition, one patient required a period of postoperative ventilation using PEEP, which may have exacerbated the shunt through the lung AVM and led to difficulty in weaning her from the ventilator.- - - - - - - - - - ranking = 0.33333333333333keywords = brain (Clic here for more details about this article) |
20/897. magnetic resonance imaging and angiography in cerebral fungal vasculitis.We report on an 11-year old girl treated for leukemia who developed infarcts in the right lentiform nucleus and temporal lobe. magnetic resonance angiography (MRA) showed mild intraluminal irregularities in the right carotid syphon and stenosis of the right proximal middle cerebral artery, suggesting vasculitis. magnetic resonance imaging (MRI) follow-up showed evolution of the initial infarct into an abscess. Stereotactic biopsy disclosed filaments of aspergillus. This report emphasizes the fact that cerebral aspergillosis should be considered if MRA and MRI are indicative of vasculitis and cerebral infarction in immunosuppressed children.- - - - - - - - - - ranking = 0.43832992580235keywords = cerebral (Clic here for more details about this article) |
