A 10-year-old, spayed female, Irish water spaniel was presented with a 2-week history of anisocoria characterized by mydriasis of the right eye compared to the left eye in ambient light. Ophthalmic and neurological examinations, combined with pharmacological testing, identified a disease process affecting the right parasympathetic nucleus of cranial nerve 3 (CN III) and/or the parasympathetic component of CN III. Magnetic resonance imaging (MRI) identified a mass involving the right midbrain and extending caudally to the rostral border of the medulla oblongata. The dog became comatose within 12 h following MRI and was euthanized. Histopathology identified the intracranial mass as a meningioma.
一只10岁已绝育的雌性爱尔兰水猎犬，出现了为期2周的瞳孔不等大症状，在环境光下右眼相较于左眼呈现瞳孔散大。眼科和神经学检查，结合药理学测试，确定了一个影响右侧动眼神经（CN III）副交感神经核和/或CN III副交感神经成分的疾病过程。磁共振成像（MRI）发现一个肿块，累及右中脑并向尾侧延伸至延髓头端边界。这只狗在MRI检查后12小时内陷入昏迷，随后实施了安乐死。组织病理学检查确定颅内肿块为脑膜瘤。
