1/14. Hearing preservation mastoidectomy in otogenic meningitis secondary to an enlarged vestibular aqueduct. Case report.In pyogenic meningitis resulting from a life-threatening ear infection, mastoidectomy is performed as part of the management of the disorder. A dilemma arises when the active ear is the only hearing ear. An active unsafe ear can lead to sensorineural hearing loss whereas ear surgery carries the risk of inner ear damage. We present the case of a 40-year-old woman admitted for severe purulent meningitis and sub-coma secondary to a left mastoiditis with mixed hearing loss on the left side and complete deafness on the right side. The study of this case shows that the intracranial complication was secondary to an abnormally enlarged left vestibular aqueduct. Because of the failure to control meningitis with medical treatment using highly specific antibiotherapy for two weeks, we proceeded with a left side mastoidectomy and closure of the external aperture of the vestibular aqueduct with a muscle graft. This surgery saved the patient's life, cured the meningitis and brought a recovery of a near normal hearing to the only hearing ear. Although demonstrating a rare etiology of intracranial complication, this case confirms that mastoidectomy, even on the only hearing ear, has to be done as early as possible to remove the source of infection, to prevent further intracranial complication, to arrest the progress of the ear disease and preserve or even recover almost normal hearing.- - - - - - - - - - ranking = 1keywords = meningitis (Clic here for more details about this article) |
2/14. Isolated monolateral neurosensory hearing loss as a rare sign of neuroborreliosis.lyme disease, or borreliosis, is a zoonosis transmitted by borrelia burgdorferi which also involves the central nervous system (CNS), in 15% of affected individuals, with the occurrence of aseptic meningitis, fluctuating meningoencephalitis, or neuropathy of cranial and peripheral nerves. Encephalopathy with white matter lesions revealed by magnetic resonance imaging (MRI) scans in late, persistent stages of lyme disease has been described. In this report, we describe a patient with few clinical manifestations involving exclusively the eighth cranial nerve, monolaterally and diffuse bilateral alterations of the white matter, particularly in the subcortical periventricular regions at cerebral MRI. This single patient study shows that the search for antibodies against Borrelia burgdoferi should always be performed when we face a leukoencephalopathy of unknown origin. An isolated lesion of the eighth cranial nerve can be the only neurologic sign in patients with leukoencephalopathy complicating lyme disease.- - - - - - - - - - ranking = 0.125keywords = meningitis (Clic here for more details about this article) |
3/14. hearing loss after discontinuing secondary prophylaxis for cryptococcal meningitis: relapse or immune reconstitution?Relapse and immune reconstitution syndrome are difficult to distinguish in hiv-infected patients treated with antiretroviral therapy (art). We report on a 26-year-old hiv-infected male (CDC C3) with hearing loss on the right side 2 months after discontinuing secondary prophylaxis for cryptococcal meningitis. CD4 cell counts had increased from 32/microl to stable counts > 200/microl for the preceding 6 months on art but hiv replication was not fully suppressed (7,000 copies/ml). magnetic resonance imaging identified lesions at the origin of the right cranial nerve VIII. Lumbar puncture revealed monocytic pleocytosis, slightly increased protein, but normal glucose and lactate levels, negative microbiological studies. fluconazole was restarted and a new art regimen was started in order to fully suppress hiv replication. Clinical and radiological signs were reversible during follow-up, and secondary prophylaxis was stopped after 6 months without adverse events. We review 26 published cases of cryptococcal infections with immune reconstitution syndrome and highlight the distinguishing features.- - - - - - - - - - ranking = 0.625keywords = meningitis (Clic here for more details about this article) |
4/14. meningitis with papillitis, choroiditis, and hearing loss: an unusual presentation of cryptococcosis in hiv infection.cryptococcosis is a common opportunistic infection in immunosuppressed patients. We present a case of cryptococcal meningitis with bilateral papillitis, multifocal choroiditis, and sensorineural hearing loss. The ocular manifestations present in this patient were unusual. The management of such cases poses a challenge because blindness and deafness can be the morbid sequelae.- - - - - - - - - - ranking = 0.125keywords = meningitis (Clic here for more details about this article) |
5/14. Sudden hearing loss due to AIDS-related cryptococcal meningitis--a temporal bone study.We have presented the clinical history and temporal bone findings in a patient who manifested sudden hearing loss, and who subsequently was found to have cryptococcal meningitis associated with AIDS. The histopathologic findings are similar to earlier reports in patients without AIDS. Because cryptococcal infection is so much more common in AIDS patients than in the general population, it must be considered a causative factor when presented with an AIDS patient with progressive or sudden hearing loss. This offers the patient a chance for timely and effective treatment.- - - - - - - - - - ranking = 0.625keywords = meningitis (Clic here for more details about this article) |
6/14. meningitis caused by streptococcus suis type II.A 49 year old head porter developed meningitis shown to be caused by streptococcus suis type II. The rare human infections with the organism, a pathogen of pigs, usually occur in those employed handling pig meat and are associated with auditory or vestibular dysfunction.- - - - - - - - - - ranking = 0.125keywords = meningitis (Clic here for more details about this article) |
7/14. Labyrinthine ossification: etiologies and CT findings.Ossification of the membranous labyrinth (labyrinthitis ossificans) develops as the final result of many inflammatory processes, for example, meningitis, blood-borne septic emboli, middle ear infection, and cholesteatoma. Labyrinthine ossification may also occur as a result of previous labyrinthectomy or secondary to trauma. Seven cases of labyrinthine ossification accompanied by severe vertigo and total hearing loss in the affected ear are discussed. The computed tomographic appearance of varying degrees of ossification, the clinical and surgical circumstances from which this disorder may develop, and the various approaches to labyrinthectomy are described.- - - - - - - - - - ranking = 0.125keywords = meningitis (Clic here for more details about this article) |
8/14. 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 = 0.625keywords = meningitis (Clic here for more details about this article) |
9/14. The temporal bone as route of infection in recurrent meningitis.Three successive episodes of recurrent meningitis in connection with an infection of the upper respiratory tract appeared to be related to a congenital idiopathic oval window CSF leak. An inner ear dysplasia was the underlying factor and accounted for the deafness and for the absence of signs of acute labyrinthis during these infectious episodes.- - - - - - - - - - ranking = 0.625keywords = meningitis (Clic here for more details about this article) |
10/14. Hearing alterations following meningitis. 1. Hearing improvement.In ten patients suffering from hearing loss following meningitis or meningoencephalitis, hearing recovery was observed. Eight of the cases had suffered from purulent meningitis, five cases had haemophilus influenzae meningitis, 1 had coli meningitis, and 1 had meningococcal meningitis. In one case, the ethiologic agent remained unknown. Two other cases had suffered from viral meningoencephalitis. Postmeningitis hearing loss was observed in 19 ears. In eight ears, the hearing loss was profound, and in eleven, it was slight to moderate. Recovery of hearing occurred in 16 ears and was complete in eight ears and partial in eight ears. Approximately one-fourth of all patients with meningitis hearing loss do recover partially or completely in both ears or only in one ear.- - - - - - - - - - ranking = 1.375keywords = meningitis (Clic here for more details about this article) |
