A Case of Intravestibular Lipoma Presenting with Sudden Hearing Loss / 대한이비인후과학회지

ABSTRACT

Intracranial lipomas are unfrequent tumors developed from mesenchymatous cells. The corpus callosum is the most frequent location (50%) in the intracranial regions, and these tumors are rarely present in the cerebellopontine angle, the internal acoustic meatus, or intravestibular lesions. With a review of literature, authors report a rare case of the left-sided intravestibular lipoma presented as sudden hearing loss in 17-year-old female. Furthermore, differential diagnostic magnetic resonance imaging characteristics of lipomas are discussed in detail.
