Papilar adenocarcinoma of endolymphatic sac is related with Von Hippel Lindau disease at 15% of cases, has a slow growing with a high local aggressiveness, and doesn't metastasize. It causes symptoms of Meniere's syndrome due to the compression that produces at endolymphatic duct. When it presents with hearing loss is usually sudden and irreversible manner. The diagnostic is made with image tests and analysis of its structure with immunohistochemical tests. The elective treatment is surgical remove, and its main complication the perioperative bleeding it can be avoided with preoperative embolization or stereotactic radiation.
A case of endolymphatic sac tumour is presented, in a 17-years-old male with unilateral deafness and crisis of rotate vertigo, with family history of Von Hippel-Lindau disease. Perceptive deafness and right vestibular arreflexia are detected at technical exploration. In a petrous bone computer tomography appears a mass at vestibular aqueduct. We performed a petrosectomy with presigmoidal approach and saving of inner ear. Pathological analysis revealed an endolymphatic sac tumour.
In patients with a family history of Von Hippel Lindau disease and clinical symptoms of vertigo and normal hearing or with slight hearing loss we should suspect the presence of endolymphatic sac tumor. The clinical presentation of hearing loss can be sudden and irreversible even with negative or inconclusive images. Therefore, a quick action is important for the preservation of this function.
内淋巴囊乳头状腺癌在15%的病例中与冯·希佩尔-林道病相关,生长缓慢但局部侵袭性高,且不发生转移。它因对内淋巴管产生压迫而导致梅尼埃综合征症状。当出现听力损失时,通常呈突然且不可逆的方式。诊断通过影像检查以及利用免疫组织化学检查分析其结构来进行。首选治疗方法是手术切除,其主要并发症是围手术期出血,术前栓塞或立体定向放射可避免这种情况。
呈现一例内淋巴囊肿瘤病例,患者为一名17岁男性,有单侧耳聋和旋转性眩晕发作史,有冯·希佩尔-林道病家族史。专科检查发现感音神经性耳聋和右侧前庭反射消失。在岩骨计算机断层扫描中,前庭导水管处出现一个肿块。我们采用乙状窦前入路并保留内耳进行了岩骨切除术。病理分析显示为内淋巴囊肿瘤。
对于有冯·希佩尔-林道病家族史且有眩晕临床症状以及听力正常或轻度听力损失的患者,我们应怀疑存在内淋巴囊肿瘤。即使影像检查结果为阴性或不确定,听力损失的临床表现也可能是突然且不可逆的。因此,迅速采取行动对于保留该功能很重要。
