An aged Connemara mare had a neurological illness lasting 3 weeks and characterised by episodes of dullness, head-pressing, staggering gait and hyperexcitability. The signs recurred at intervals of 3 to 4 days, with intervening periods of apparent normality. Post-mortem examination revealed an epidermoid cyst on the dorsal surface of the occipital lobe of the left cerebral hemisphere. The cyst was lined by stratified squamous epithelium and contained desquamated keratinised material and blood. The lesion is considered to be a congenital malformation which enlarges and produces space-occupying signs.
一匹老龄康尼马拉母马患有一种持续3周的神经系统疾病，其特征为精神沉郁、头顶按压、步态蹒跚和过度兴奋发作。这些症状每隔3至4天复发一次，其间有明显正常的间歇期。尸检发现左大脑半球枕叶背侧有一个表皮样囊肿。囊肿内衬复层鳞状上皮，含有脱落的角质化物质和血液。该病变被认为是一种先天性畸形，会不断扩大并产生占位性体征。
