A 4-year-old female Chihuahua was presented with progressive seizures, blindness and lethargy. Neurolocalisation was consistent with a diffuse brain lesion affecting the forebrain and cerebellum. MRI demonstrated dilation of the subarachnoid space dorsolaterally surrounding the cerebrum, filled with cerebrospinal fluid (CSF). Ventricular system size was normal, but mild cerebral atrophy was suspected. There was pachymeningeal contrast enhancement, but CSF analysis was unremarkable. This lesion was interpreted to be an external hydrocephalus of suspected congenital origin.
一只4岁雌性吉娃娃犬出现进行性癫痫发作、失明和嗜睡症状。神经定位结果与影响前脑和小脑的弥漫性脑损伤一致。磁共振成像（MRI）显示大脑背外侧蛛网膜下腔扩张，充满脑脊液（CSF）。脑室系统大小正常，但怀疑有轻度脑萎缩。有硬脑膜对比增强，但脑脊液分析无异常。该病变被解释为疑似先天性起源的外部脑积水。
