A cerebellopontine angle (CPA) lipoma in a 17 year-old woman is reported. The patient was admitted for evaluation of episodic vertigo, preauricolar pain and progressive hearing loss on the right ear. Auditory brain stem evoked potentials revealed an interwave latency increase on the right ear. Computerized Tomography and Magnetic Resonance Imaging showed a low density lesion and high intensity signal, respectively, in the right CPA. Reports of surgically treated lipomas of the CPA are extremely rare. Our patient underwent a right lateral suboccipital craniotomy and a subtotal resection of the lesion. Histological examination revealed a richely vascularized lipomatous tissue traversed by nerve fibers. The surgical indication for such rare lesion is discussed.
报告了一名17岁女性的桥小脑角（CPA）脂肪瘤。该患者因发作性眩晕、耳前疼痛和右耳进行性听力损失入院评估。听觉脑干诱发电位显示右耳波间期潜伏期延长。计算机断层扫描和磁共振成像分别显示右CPA区有低密度病变和高强度信号。关于CPA脂肪瘤手术治疗的报道极为罕见。我们的患者接受了右枕下外侧开颅手术和病变次全切除术。组织学检查显示富含血管的脂肪组织中有神经纤维穿过。讨论了这种罕见病变的手术指征。
