BACKGROUND
The pathogenesis of hearing loss caused by cerebellopontine angle tumors such as acoustic neuromas is unknown. The lack of loudness recruitment is thought to be one of the features of retrocochlear hearing impairment. In contrast to conventional suprathreshold tests, the categorial
We report the case of a 60-year-old woman in whom migraine with typical aura heralded the presence of an occipital lobe tumor. Her headache was characterized by recurrent episodes of visual aura confined to the left visual field followed by right hemicranial throbbing headaches accompanied by
OBJECTIVE
To highlight the importance of a broad differential and histopathologic confirmation in patients with newly diagnosed cancer with brain lesions atypical for CNS metastasis.
METHODS
We report 2 cases of biopsy-proven CNS vasculitis in patients undergoing treatment for a newly diagnosed
Inner ear damage can lead to hearing disorders, including tinnitus, hyperacusis, and hearing loss. We measured the effects of severe inner ear damage, produced by cochlear ablation, on the levels and distributions of amino acids in the first brain center of the auditory system, the cochlear nucleus.
Pilomyxoid astrocytomas have been identified as a variant of pilocytic astrocytoma. They are listed as a novel clinico-pathological entity in the 2007 World Health Organisation (WHO) classification of tumours of the central nervous system. This tumour corresponds to a WHO grade II neoplasm whereas
BACKGROUND
Neurofibromas are benign nerve sheath tumors that usually affect peripheral nerves and are related to neurofibromatosis type 1; however, they have not been described as a cause of intraparenchymal brain tumor.

Of the 150 patients admitted in 2001 to the Tinnitus Center located at the Nofer Institute of Occupational Medicine, Łódź, Poland, 80 were subjected to complex examinations consisted of standardized questionnaire on medical history, psychological tests and audiological assessment. The diagnostic
Meningoencephalitis is an acute inflammation of the brain and spinal cord & their covering protective membranes. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency. The commonest
There are three times as many outer hair cells (OHC) as inner hair cells (IHC), yet IHC transmit virtually all acoustic information to the brain as they synapse with 90-95% of type I auditory nerve fibers. Here we review a comprehensive series of experiments aimed at determining how loss of the
Tinnitus is one of the most common hearing disorders, with wide-ranging risk factors including age, hearing loss, noise exposure, inflammatory diseases or tumors of the ear, ototoxic drugs, head or cervical vertebra trauma, and psychological disorders (e.g., anxiety and depression). Tinnitus can be
