Lipoma of the cerebellopontine angle is a very rare tumor. We report the case of a 14-years-old female, with left side deafness during three years, associated with headache. CT scan showed an hypodense mass, without enhancement at the cerebellopontine angle. The patient was treated surgically by left retrosigmoid approach. The lesion involved the eighth and seventh cranial nerves and only a partial removal was performed. The postoperative course was uneventful. She had no more headache; the deafness of the left side remained unchanged. Asymptomatic lipoma of the cerebellopontine angle can be treated conservatively, although those with progressive symptoms should be treated surgically, with total or partial remove based on their neurovascular involvement.
桥小脑角脂肪瘤是一种非常罕见的肿瘤。我们报告一例14岁女性病例,其三年来左侧耳聋并伴有头痛。CT扫描显示桥小脑角有一低密度肿块,无强化。患者通过左侧乙状窦后入路接受手术治疗。病变累及第八和第七颅神经,仅进行了部分切除。术后过程顺利。她不再头痛;左侧耳聋情况未变。无症状的桥小脑角脂肪瘤可保守治疗,不过有进行性症状的患者应接受手术治疗,根据其神经血管受累情况进行全切或部分切除。
