BACKGROUND
This case report describes the clinical presentation, magnetic resonance imaging (MRI) as well as the histopathological findings in an elderly cat with an intracranial cholesterol granuloma.
CASE PRESENTATION
An 11.5-year-old, male neutered cat was presented at the emergency service with deteriorating behavioral changes including aggression, and progressive generalized ataxia. Magnetic resonance imaging (MRI) of the brain revealed a large, well demarcated, inhomogeneous and contrast enhancing mass in the lateral ventricles with marked mass effect. Due to a poor clinical prognosis, the cat was euthanized. Histological examination identified the mass as a bilateral cholesterol granuloma in the choroid plexus of the lateral ventricles.
CONCLUSIONS
Although plexus cholesterol granulomas are rarely seen in cats, they should be considered as a differential diagnosis in elderly patients with neurological signs such as behavioral changes.
背景
本病例报告描述了一只老年猫颅内胆固醇肉芽肿的临床症状、磁共振成像（MRI）以及组织病理学发现。
病例介绍
一只 11.5 岁的雄性去势猫因行为改变（包括攻击性和进行性全身性共济失调）而在急诊就诊。脑部磁共振成像（MRI）显示侧脑室有一个大的、边界清楚的、不均匀的、增强的肿块，伴有明显的肿块效应。由于临床预后不佳，这只猫被安乐死了。组织学检查发现，该肿块是侧脑室脉络丛的双侧胆固醇肉芽肿。
结论
虽然猫的脉络丛胆固醇肉芽肿很少见，但对于有行为改变等神经症状的老年患者，应将其作为鉴别诊断之一。
