1/14. Primary CNS lymphoma associated with streptococcal abscess: an autopsy case.This report describes a case of streptococcal abscess in the nodules of a primary central nervous system (CNS) lymphoma. magnetic resonance imaging (MRI) of the brain revealed multiple lesions with ringlike enhancement over the bilateral frontal, right temporal, and left parietal lobes. On admission, acute brain edema occurred following angiography, which resulted in respiratory arrest. autopsy findings showed that the ringlike enhanced lesions on MRI were streptococcal abscesses localized in the lymphoma nodules. The lymphoma was classified as non-Hodgkin, diffuse large cells of B-cell lineage. No other lymphoma mass was found extracranially. An immunohistochemical study showed that the lymphoma cells were positive for leukocyte common antigen, Epstein-Barr virus, bax. and bcl-XL, and negative for L-26 and bcl-2. This case demonstrated that an opportunistic streptococcal abscess developed in primary CNS lymphoma in a patient without acquired immunodeficiency syndrome (AIDS), though a few similar cases have been reported in patients with AIDS.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
2/14. Toxoplasmic encephalitis in patients with acquired immunodeficiency syndrome--four case reports.Four patients, all males aged 40-64 years, presented with toxoplasmic encephalitis associated with human immunodeficiency virus (hiv) infection manifesting as nonspecific neurological deficits such as epilepsy or hemiparesis. magnetic resonance imaging showed single or multiple lesions with ring enhancement, mimicking metastatic brain tumor or brain abscess. Marked eosinophilia was noted in three patients. Two patients who received anti-toxoplasma chemotherapy in the early stage had a good outcome. However, the other two patients suffered rapid neurological deterioration and needed decompressive surgery, resulting in a poor outcome. toxoplasma diffusely infects the whole central nervous system from the early stage. The outcome for patients who needed emergency surgery was poor. Therefore, this rare but increasingly common infectious disease must be considered in the differential diagnosis of a patient with neuroimaging findings similar to those of metastatic tumor or brain abscess. Appropriate chemotherapy should be started immediately after hiv-positive reaction is identified in patients with single or multiple mass lesions with ring enhancement.- - - - - - - - - - ranking = 0.28571428571429keywords = abscess (Clic here for more details about this article) |
3/14. Pituitary abscess presenting with cranial nerve paresis. Case report and review of literature.Non-adenomatosus lesions of the pituitary represent a small part of the intrasellar processes and they have heterogeneous presentation. Making a precise diagnosis is of great importance, as it may lead to more efficient management. A 65-year-old man was admitted to the hospital because of headache and right cranial nerve III palsy. Basic laboratory work-up was normal whereas endocrinological assessment revealed hypopituitarism without diabetes insipidus. Plain radiography showed an enlarged sella and frontal and paranasal sinusitis. Computed tomography (CT) and magnetic resonance imaging (MRI) of the sella revealed an intrasellar lesion with extension to the sphenoid and cavernous sinuses as well as the suprasellar region, exerting pressure on the optic chiasm. On T1-weighted images the mass had a low-intensity signal with a smooth enhancing rim with bright signal. Given the presence of multiple sinusitis and imaging characteristics a pre-operative diagnosis of pituitary abscess was made. The patient was operated via transphenoidal route and purulent material was drained out. Cultures of the material were positive for staphylococcus aureus. Antibiotics as well as cortisol replacement therapy were given. Three months later hypopituitarism persisted but there was significant improvement in the neurological findings. We report a case of an unusual presentation of a pituitary abscess. High index of suspicion, the presence of associated conditions such as pituitary tumors, meningitis or sinusitis, as well as diabetes insipidus and specific imaging features are the main diagnostic clues. Pre-operative diagnosis, which will lead to prompt antibiotic therapy and transphenoidal drainage, can decrease high mortality and morbidity associated with this disease.- - - - - - - - - - ranking = 0.85714285714286keywords = abscess (Clic here for more details about this article) |
4/14. brain abscess complicating cerebral infarct.PRESENTATION: We report a case of a 68-year-old man who suffered ischemic strokes in the left middle cerebral artery territory and three months later, following urosepsis, developed a cerebral abscess in the infarcted area. DISCUSSION: A literature search found only eight other cases. We discuss herein the common clinical aspects of brain abscess complicating strokes, the co-existent diseases, and point out the possibility of underreporting this rare but treatable complication. CONCLUSION: Cerebral abscess should be suspected in patients with a previous brain infarction or haemorrhage, who develop bacteremia and impaired consciousness without a clear explanation to their condition. Advanced age, and medical conditions known adversely to affect immunological competence reinforce the clinical suspicion.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
5/14. Intraventricular rupture of Nocardia brain abscess--case report.A 71-year-old male presented with left hemiparesis and confused conversation. Computed tomography showed a mass lesion with rim enhancement in the right parietal lobe. He developed meningeal irritation the day after admission. Emergent fluid-attenuated inversion recovery (FLAIR) magnetic resonance (MR) imaging revealed a clear hyperintense component in the right lateral ventricle and niveau formation inside the intracerebral lesion, indicating intraventricular rupture of the brain abscess. The patient underwent aspiration of the abscess and ventricular drainage with antibiotic administration. nocardia asteroides was isolated from the aspirated pus, so systemic and direct administration of effective antibiotics was subsequently commenced. These procedures resulted in gradual improvement of his clinical course, and he left our hospital. Several days after discharge, he developed acute pan-peritonitis due to malignant lymphoma. He appeared to be progressively deteriorating after an exploratory laparotomy, and died on the 17th day after the laparotomy. Intraventricular rupture of nocardia brain abscess can be successfully treated after early definitive diagnosis with FLAIR MR imaging.- - - - - - - - - - ranking = 1keywords = abscess (Clic here for more details about this article) |
6/14. Intracerebral pneumocephalus and hemiparesis as a complication of a halo vest in a patient with multiple myeloma. Case report.A halo orthosis is often used to immobilize the cervical spine after severe injury in patients who cannot tolerate surgery. Although complications such as pin loosening or brain abscess have been reported, there are no reported cases of hemiparesis following pneumocephalus associated with halo use. The authors report the case of a 77-year-old man with multiple myeloma who, after undergoing halo vest therapy and chemotherapy, suddenly developed hemiparesis and speech disturbance. Diagnostic neuroimaging demonstrated penetration of the inner table at the right posterior pin site and intracerebral pneumocephalus at the parietal lobe. Intraoperative inspection revealed only air and no purulent materials or cerebrospinal fluid in the cystic lesion. When a halo device is used, attention to detail in pin application, maintenance, and proper pin-site care must be undertaken to minimize complications. The tightening of the pin in cases in which late-onset loosening has occurred should not be performed. Additionally, because late loosening of the pin and pin-site infection increase the risks of complications, a halo vest should be used only as a short-term treatment, and the clinician should be aware of the possible increased risk of serious complications such as pneumocephalus or subdural abscess formation.- - - - - - - - - - ranking = 0.28571428571429keywords = abscess (Clic here for more details about this article) |
7/14. Cerebral actinomycosis before adolescence.In a 10-year-old boy presenting with focal seizures and 6 months later with acute right-sided hemiparesis, the diagnosis of a cerebral abscess due to actinomyces israelii was established. The immunocompetent child suffered from a complex congenital heart disease with pulmonary arteriovenous shunts and pulmonary hypertension causing mild cyanosis. His parents had been reluctant to agree to neuroimaging investigations resulting in a delayed diagnosis. Despite the long interval between first symptoms and commencement of treatment including neurosurgical excision of the abscess followed by a 4-week course of ceftriaxone, a complete recovery of the hemiparesis was observed. This patient is the first case with cerebral actinomycosis before adolescence reported so far.- - - - - - - - - - ranking = 0.28571428571429keywords = abscess (Clic here for more details about this article) |

9/14. Symptomatic hematoma of cervical ligamentum flavum: case report.STUDY DESIGN: A case of symptomatic hematoma of cervical ligamentum flavum. OBJECTIVE: To report the first ligamentum flavum hematoma in the cervical spine and review the reported cases. SUMMARY OF BACKGROUND DATA: A herniated nucleus pulposis, spondylosis, epidural hematoma or abscess, neoplasm, or some pathology of the ligamentum flavum, such as hypertrophy, ossification, or calcification, are the most common causes of spinal cord and nerve root compression. A ligamentum flavum hematoma has also been reported as a cause of compression of the cauda equina and lumbar nerve roots but has never been found in the cervical spine. methods: A 72-year-old man presented with left upper arm pain and left hemiparesis following traditional massage therapy. Admission magnetic resonance images showed a posterior oval-shaped mass that was continuous with the ligamentum flavum at C3-C4 level. RESULTS: A C3-C4 laminectomy for decompression and resection of the lesion was performed. One year after surgery, the patient remained neurologically intact and symptom-free. CONCLUSIONS: hematoma of the ligamentum flavum occurring in the cervical spine has never been reported previously. Repeated trivial injury on a degenerative ligamentum flavum might be the leading predisposing factor. spine surgeons should be aware of a hematoma in the ligamentum flavum as a possible cause of spinal cord or root compression, especially in the mobile cervical and lumbar spine.- - - - - - - - - - ranking = 0.14285714285714keywords = abscess (Clic here for more details about this article) |
