A 21-kg, seven-year-old, male, mixed-breed Labrador retriever was admitted for incoordination and a head tilt of approximately three months' duration. Ataxia was noted of the trunk and limbs, and there was a head tilt to the right side. Conscious proprioceptive deficits were present in the left thoracic and pelvic limbs (i.e., hemiparesis). These abnormalities were consistent with paradoxical vestibular syndrome and a lesion involving the caudal cerebellar peduncle. A mass lesion consisting primarily of fluid was present on magnetic resonance imaging and at craniectomy. Histopathological diagnosis was a cystic meningioma. Based upon previous reports and experience, the location of this tumor was unusual.
一只21千克、7岁的雄性混种拉布拉多猎犬因共济失调和头部倾斜约三个月而入院。发现躯干和四肢共济失调，头部向右侧倾斜。左胸肢和盆腔肢存在意识性本体感觉障碍（即偏瘫）。这些异常与反常性前庭综合征及涉及小脑尾侧脚的病变相符。磁共振成像及颅骨切除术显示存在一个主要由液体组成的肿块病变。组织病理学诊断为囊性脑膜瘤。根据既往报告和经验，该肿瘤的位置不寻常。
