Intracochlear schwannoma is a rare, treatable, cause of unilateral hearing loss. Due to the small size, position, and variable clinical and imaging features, diagnosis presents a significant challenge and is often delayed. We present a case of a patient with an intracochlear schwannoma presenting as a diffuse enhancement of the cochlea, mimicking an infectious or inflammatory process. The absence of focal nodularity in this lesion on multiple high-resolution MRI examinations led to a delay of over 3 years from the patient's initial presentation to surgical diagnosis. Clinical history and examination, imaging features, pathologic findings, and surgical management options are described.
耳蜗神经鞘瘤是一种罕见的、可治疗的单侧听力损失的原因。由于肿瘤体积小、位置深、临床表现和影像学特征多变，诊断极具挑战性，常常会被延误。我们报告了一例以耳蜗弥漫性强化为表现的耳蜗神经鞘瘤患者，这种表现类似于感染或炎症过程。由于该病变在多次高分辨率 MRI 检查中均未见局灶性结节，导致从患者初次就诊到手术诊断的时间延误了 3 年以上。本文介绍了该病例的临床病史和检查、影像学特征、病理结果以及手术治疗选择。
