A case report: The cerebral metabolic rate of oxygen evaluated by 15O positron emission tomography may predict the recovery of cortical deafness due to bilateral cerebral hemorrhage.
Cortical deafness is a rare central auditory disorder resulting in severe hearing loss. It is caused by bilateral damage to the auditory cortex, auditory radiation, or medial geniculate body. We herein report a case of cortical deafness recovery caused by left thalamic hemorrhage following right putaminal hemorrhage. The evaluation of the cerebral metabolic rate of oxygen (CMRO2) using 15O positron emission tomography (15O-PET) at the onset helped predict the functional outcomes. A CMRO2 evaluation using 15O-PET was valuable for predicting the outcome of cortical deafness. We should remain aware of the possibility of cortical deafness in stroke patients with bilateral temporal lobe lesions, basal ganglia lesions near auditory tracts, or brainstem lesions, including those with preexisting lesions.
期刊介绍：
eNeurologicalSci provides a medium for the prompt publication of original articles in neurology and neuroscience from around the world. eNS places special emphasis on articles that: 1) provide guidance to clinicians around the world (Best Practices, Global Neurology); 2) report cutting-edge science related to neurology (Basic and Translational Sciences); 3) educate readers about relevant and practical clinical outcomes in neurology (Outcomes Research); and 4) summarize or editorialize the current state of the literature (Reviews, Commentaries, and Editorials). eNS accepts most types of manuscripts for consideration including original research papers, short communications, reviews, book reviews, letters to the Editor, opinions and editorials. Topics considered will be from neurology-related fields that are of interest to practicing physicians around the world. Examples include neuromuscular diseases, demyelination, atrophies, dementia, neoplasms, infections, epilepsies, disturbances of consciousness, stroke and cerebral circulation, growth and development, plasticity and intermediary metabolism. The fields covered may include neuroanatomy, neurochemistry, neuroendocrinology, neuroepidemiology, neurogenetics, neuroimmunology, neuroophthalmology, neuropathology, neuropharmacology, neurophysiology, neuropsychology, neuroradiology, neurosurgery, neurooncology, neurotoxicology, restorative neurology, and tropical neurology.
