1/9. Hypertrophic chronic pachymeningitis associated with chronic otitis media and mastoiditis.We describe the case history of a 70-year-old female patient presenting with bilateral hearing disturbance, facial paralysis, and vertigo. Radiological tests of temporal bone revealed soft tissue in the mastoid and tympanic cavities, and T1 weighted MRI revealed prominent Gd enhancement of the middle skull basal meninges. Middle ear inflammation appeared to induce pachymeningitis and to exacerbate associated symptoms, leading to a decline in the patient's overall condition. Bilateral mastoidectomies were effective in improving her general condition. Her hearing improved only on the right side because ossiculoplasty was performed only on that side. Her facial movement progressively improved and pachymeningitis diminished over time. We speculate that removal of the infectious granulation within the middle ears and mastoids ameliorated the acute inflammation. The etiology remains unknown in this case.- - - - - - - - - - ranking = 1keywords = pachymeningitis, meningitis (Clic here for more details about this article) |
2/9. spinal cord compression and bilateral sensory neural hearing loss: an unusual manifestation of neurocysticercosis.neurocysticercosis is the most common parasitic infestation involving the central nervous system in tropical countries. Common presentations are seizure, meningitis and increased intracranial pressure. The authors report a case of a 52-year-old woman with racemose neurocysticercosis in the subarachnoid space at the cistern of the brain through the lumbar cistern. She presented with progressive paraparesis due to spinal cord compression and finally had progressive bilateral sensori-neural hearing loss. MRI brain and the whole spinal cord revealed numerous rim-enhancing cystic lesions at the basal cistern, prepontine cistern, bilateral cerebellopontine angle, internal acoustic canals, intramedullary lesion at the 5th cervical spinal level, lumbar cistern lesions and secondary syringomyelia at the thoracic spinal cord. The histopathologic examination confirmed cysticercosis. After treatment by albendazole and surgical removal, she still developed recurrent spinal compression at a higher level and obstructive hydrocephalus. Finally, she died from status epilepticus and septic shock.- - - - - - - - - - ranking = 0.0078509887435688keywords = meningitis (Clic here for more details about this article) |
3/9. Auditory brainstem implantation to rehabilitate profound hearing loss with totally ossified cochleae induced by pneumococcal meningitis.Hearing rehabilitation by cochlear implantation is not always possible in case of total ossification after pneumococcal meningitis. We report 3 cases of postmeningitis profound hearing loss with total cochlear ossification in adults who underwent auditory brainstem implantation (Nucleus 22, Cochlear Inc., Lane Cove, australia) between 1999 and 2004. The postoperative follow-up period ranged from 1 to 6 years. Eleven to 15 out of 22 electrodes were activated. All patients had significant speech discrimination in the sound-only mode and an enhanced lip-reading performance with the implant. Auditory brainstem implants are an efficient means of auditory rehabilitation and may be considered in selected cases of bilateral profound hearing loss with the impossibility of cochlear implantation.- - - - - - - - - - ranking = 0.047105932461413keywords = meningitis (Clic here for more details about this article) |
4/9. Audiological characteristics of hearing loss following meningitis.meningitis is one of the leading causes of acquired sensorineural hearing loss in childhood, and many retrospective and prospective studies and case reports have been published. However, they have seldom discussed the nature of postmeningitic hearing loss from the audiological point of view. This study reports the results of audiological examinations performed on 5 patients suffering from hearing loss following meningitis. Extremely poor word discrimination scores as compared with pure-tone audiograms were common in all 5 cases. Type IV Bekesy tracings were observed in 2 cases. Discrepancies between pure-tone audiograms and subjective hearing sensation and between pure-tone audiograms and ABR recordings were noted in 2 cases. These results suggest that varying degrees of retrocochlear involvement complicating the inner ear damage are the audiological characteristics of hearing loss following meningitis.- - - - - - - - - - ranking = 0.047105932461413keywords = meningitis (Clic here for more details about this article) |
5/9. The pattern and stability of postmeningitic hearing loss in children.Following meningitis, 280 children (168 boys, 112 girls) had audiological assessment, and 87 (31%) were initially found to have a sensorineural hearing loss in one or both ears. Twenty-three children were followed elsewhere. Of 64 children followed for an average of 3.46 years, 55 (86%) exhibited stable auditory thresholds over time, most commonly (24) bilateral, profound/anacusic losses. One moderate and four severe losses were identified, but no bilateral, mild losses. Nineteen children had asymmetric losses with varied audiometric configurations. Seven children presented with a unilateral hearing loss, again with a range of configurations. Auditory thresholds changed over time in nine children, either improving, declining, or fluctuating, over a variable interval ranging from 1 month to 12 years.- - - - - - - - - - ranking = 0.0078509887435688keywords = meningitis (Clic here for more details about this article) |
6/9. temporal bone histopathology in deafness due to cryptococcal meningitis.This paper reports on a patient who survived an attack of cryptococcal meningitis eight years prior to his death. A bilateral sensorineural hearing loss had been noted a short time before the patient was admitted to the hospital, and was the only complication after he recovered from the disease. Histopathologic study of the temporal bones showed a similar pattern of pathology in both ears, the most striking finding being a severe loss of spiral ganglion cells in Rosenthal's canal, and of cochlear nerve fibers in the osseous spiral lamina and internal auditory meatus. The vestibular nerve was mostly free from pathology. The organ of corti was atrophic but the hair cell population appeared to be almost normal. A slight number of cryptococci were observed in limited areas of the cochlear and the saccular nerves in the internal auditory meatus. The severe pathology of the cochlear nerve was compatible with audiologic evaluations, which pointed to a retrocochlear lesion. Thus, this case demonstrates some characteristic aspects of cryptococcal infection of the temporal bone: The primary site of invasion was the cochlear nerve in the internal auditory meatus and the modiolus, leading to the loss of ganglion cells and nerve fibers, while the vestibular nerve appears to have been resistant to infection.- - - - - - - - - - ranking = 0.039254943717844keywords = meningitis (Clic here for more details about this article) |
7/9. Meniere's disease in infants.We described 3 patients who, from early infancy, evidenced attacks of vomiting associated with fluctuating hearing loss, culminating in bilateral severe sensorineural hearing loss. The patients suffered from Meniere's disease, according to all clinical yardsticks. The patients described by us were at first diagnosed and treated for gastroenteritis or meningitis. Meniere's disease was not suspected. We want to point out that Meniere's disease, though usually presenting itself at middle age, may well start in childhood as well as in infancy, and should be suspected whenever vomiting, without diarrhea, is associated with some hearing loss at any age--no matter how young the patient is. It is also possible that some sensorineural hearing losses in late childhood or adulthood are in effect the end result of burnt-out Meniere's disease--as our second case presented himself.- - - - - - - - - - ranking = 0.0078509887435688keywords = meningitis (Clic here for more details about this article) |
8/9. Sudden bilateral hearing loss and meningitis in adults.Sudden profound bilateral sensorineural hearing loss is a serious complication of bacterial meningitis. With high dosage dexamethasone it is possible to halt, and, in some instances, to reverse the progression of the hearing loss. The efficacy of treatment depends upon early diagnosis. Hearing may worsen upon steroid cessation and low dosage oral steroid may be required for several months. The eventual hearing loss may be considerably worse than anticipated. Two cases illustrating differing aspects of the disease are described.- - - - - - - - - - ranking = 0.039254943717844keywords = meningitis (Clic here for more details about this article) |
9/9. Cryptococcal meningitis with severe visual and hearing loss and radiculopathy in a patient without immunodeficiency.cryptococcosis is an important cause of lymphocytic meningitis, especially but not necessarily in immunocompromised patients. We present the case of a 23-year-old man with a severe and rapid course of a cryptococcal meningoencephalitis, which led to visual and hearing loss, psychotic illness and radiculopathy. There was no evidence of immunodeficiency. Treatment with amphotericin b and flucytosine led to improvement of the symptoms but did not eradicate the micro-organisms from the cerebrospinal fluid (CSF). maintenance therapy with fluconazole was necessary and led to improvement of the CSF pathology.- - - - - - - - - - ranking = 0.039254943717844keywords = meningitis (Clic here for more details about this article) |
