1/183. Delayed recurrence of cerebellar abscess 20 years after excision of dermoid cyst and sinus.A patient is described who suffered a greatly delayed reappearance of a cerebellar abscess, 20 years after excision, in childhood, of a midline dermoid cyst with associated abscess formation. A similar organism was cultured on both occasions.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/183. actinomycosis of the central nervous system: surgical treatment of three cases.Three cases of actinomycotic brain infection are described, 2 of which manifested as cerebral abscess, the third as epidural empyema. Complete resolution of the infection was always achieved by means of surgical treatment and prolonged antibiotic therapy. The cases reported emphasize the importance of a combined approach in the treatment of this unusual cause of brain infection.- - - - - - - - - - ranking = 126.19906720312keywords = central nervous system, nervous system (Clic here for more details about this article) |
3/183. role of stereotactic aspiration in the management of tuberculous brain abscess.BACKGROUND: Intracranial tuberculous abscesses are uncommon clinical entities, even in countries where tuberculosis is endemic. Surgical excision and antituberculous treatment is the treatment of choice. The role of stereotactic aspiration in the management of these lesions is highlighted in this communication. methods: Three patients, all receiving treatment for pulmonary tuberculosis, presented with symptoms of raised intracranial pressure and neurological deficits. Computed tomography (CT) scans revealed cystic lesions with enhancing rim in the thalamus in two patients and multiple coalescing cystic lesions in the deep temporal region in another. RESULTS: Stereotactic aspiration of the cyst and biopsy of the cyst wall were performed in all. In two, the pus revealed acid fast bacilli (AFB). In another, though the pus did not reveal any AFB, the wall showed tuberculous granuloma. Antituberculous treatment was continued in all the patients. Follow-up CT revealed resolution of the lesions in all patients. CONCLUSION: Stereotactic aspiration is an useful alternative modality of management of tuberculous abscesses in a selected group of patients.- - - - - - - - - - ranking = 0.8keywords = cyst (Clic here for more details about this article) |
4/183. brain abscess caused by cladosporium trichoides (Bantianum): a case with paranasal sinus involvement.Dematiacious fungi (ie, fungi with dark hyphae) are a rare and usually fatal cause of central nervous system infection. cladosporium trichoides has been implicated most frequently. documentation of extra-CNS involvement has been rare. Our patient had a brain abscess and paranasal sinus infection due to C trichoides. The organism was sensitive to less than or equal 2mug/ml of flucytosine. Although our patient did not receive flucytosine, it is possible that this drug, because of its excellent penetration into the cerebrospinal fluid, may be a useful therapeutic agent in cerebral cladosporiosis.- - - - - - - - - - ranking = 31.549766800779keywords = central nervous system, nervous system (Clic here for more details about this article) |
5/183. 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 = 0.2keywords = cyst (Clic here for more details about this article) |
6/183. 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 = 0.2keywords = cyst (Clic here for more details about this article) |
7/183. 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 = 0.2keywords = cyst (Clic here for more details about this article) |
8/183. Successful treatment of brainstem abscess with stereotactic aspiration.BACKGROUND: Brainstem abscess is an uncommon condition associated with a high mortality. We report a case of brainstem abscess in a 51-year-old female with a pulmonary arteriovenous fistula that was cured after appropriate antibiotic therapy following stereotactic aspiration. The value of stereotactic aspiration in the management of brainstem abscess is documented with a review of the relevant literature. CASE REPORT: A 51-year-old female with a pulmonary arteriovenous fistula suffered fever, diplopia and weakness on the right side. Magnetic resonance (MR) imaging of the brain showed a large cystic mass with ring-like enhancement in the brainstem. A diagnosis of brainstem abscess as a complication of pulmonary arteriovenous fistula was made. MR imaging-guided stereotactic exploration was carried out via the suboccipital transcerebellar approach and the pathogen of the brainstem abscess was identified. The brainstem abscess was cured after treatment employing antibiotics to which the pathogen was sensitive. CONCLUSIONS: Stereotactic aspiration is an effective procedure for brainstem abscesses. This procedure is less invasive than open surgery and can be performed even in patients in poor general condition.- - - - - - - - - - ranking = 0.2keywords = cyst (Clic here for more details about this article) |
9/183. 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 = 31.549766800779keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/183. Management and outcome of brain abscess in renal transplant recipients.Although infection is the commonest central nervous system complication following renal transplantation, brain abscess is uncommon. Over the last 11 years, five renal transplant recipients who had brain abscesses were treated by computed tomography (CT)-guided stereotactic aspiration. Three patients had a fungal abscess, one a tuberculous abscess and the other had a methicillin-resistant staphylococcus aureus abscess. One patient required a craniotomy for the excision of a fungal abscess which was persistent after two CT-guided stereotactic aspirations. The survivors in this group are the patient with a tuberculous abscess who is alive and well 5 years after diagnosis, and another with a dematiaceous fungal abscess (phaeohyphomycosis). CT-guided stereotactic surgery is minimally invasive, and can safely be performed in these patients. It often leads to an aetiological diagnosis in renal transplant recipients with brain abscesses. Specific antibiotic management directed towards the causative organism rather than empirical treatment can be instituted following the procedure. Although the ultimate prognosis in these patients is bleak even with specific antibiotic therapy, an occasional patient might have a good outcome with prompt and appropriate therapy.- - - - - - - - - - ranking = 31.549766800779keywords = central nervous system, nervous system (Clic here for more details about this article) |
