Intracranial lipoma is an uncommon entity. A rare type of tumor in the internal auditory canal (IAC) and the cerebellopontine angle (CPA) is lipoma. There are a few case reports in the literature related to intravestibular lipoma. Herein, we report a case of lipomas within the cerebellopontine angle and vestibule of the inner ear in a patient with tinnitus and dizziness. The patient was evaluated with a 1.5 T magnetic resonance imaging (MRI) system. MRI and CT showed the masses in the left CPA and the left IAC. These lesions were hyperintense on both T1- and T2 weighted images and showed no enhancement after gadolinium administration. Conservative management was suggested. Histopathological diagnosis is rarely necessary with the widespread use of magnetic resonance imaging. Considering significant morbidity during resection, conservative follow-up is the best approach for CPA and IAC lipoma.
颅内脂肪瘤是一种罕见的疾病。脂肪瘤是内耳道（IAC）和桥小脑角（CPA）中一种罕见的肿瘤类型。文献中有几例关于前庭内脂肪瘤的病例报告。在此，我们报告一例患有耳鸣和头晕的患者，其桥小脑角和内耳前庭存在脂肪瘤。患者接受了1.5 T磁共振成像（MRI）系统检查。MRI和CT显示左侧CPA和左侧IAC有肿块。这些病变在T1加权像和T2加权像上均呈高信号，钆剂注射后无强化。建议采取保守治疗。随着磁共振成像的广泛应用，组织病理学诊断很少有必要。考虑到切除过程中会有显著的发病率，对于CPA和IAC脂肪瘤，保守随访是最佳方法。
