Abstract

Intralabyrinthine schwannomas (ILS) are rare benign tumors, often responsible for hearing loss. MRI is important in establishing the diagnosis. We present the example of a 48-year-old lady who reported a 3-years history of right-sided sensorineural deafness. MRI demonstrated a loss of the normal hypersignal of the second turn of the right cochlea compatible with intracochlear schwannoma.

摘要

碱性神经鞘瘤（ILS）是罕见的良性肿瘤，通常负责听力损失。MRI对建立诊断具有重要意义。我们介绍了一位48岁的女士的例子，她报告了3年的右侧感音神经性耳聋病史。MRI显示与耳蜗内神经鞘瘤相容的右耳蜗第二转弯的正常超信号丢失。
