Coenurosis is a disease of the central nervous system in sheep, caused by Coenurus cerebralis, the larval stage of Taenia multiceps, a tapeworm, which infests the small intestine of carnivores. In 80-90% of cases, the cyst is located in one cerebral hemisphere, whilst in 5-10% of cases, it is localised in the cerebellum; rarely it involves two sites in the brain of the affected animal. Listeriosis, louping-ill, sarcocystosis and polioencephalomalacia and brain abscessation should be considered when formulating a diagnosis of acute coenurosis. In all cases, it is essential to carefully examine the animal and not simply rely on results of ancillary tests (mainly of cerebrospinal fluid examination), as disorders other than coenurosis can be responsible for changes in the results of these tests. Treatment is based on surgical removal of the coenurus cyst after general anaesthesia of the animal; the approach has a very good success rate, especially after accurate localisation of the lesion. Despite that, many farmers may choose to slaughter those sheep fit for marketing for economic reasons and euthanise those in poor condition.
多头蚴病是一种绵羊中枢神经系统疾病，由多头绦虫的幼虫 Coenurus cerebralis 引起，该绦虫寄生在肉食动物的小肠中。在 80-90%的病例中，囊肿位于一个大脑半球，而在 5-10%的病例中，囊肿位于小脑；在极少数情况下，它会累及受影响动物的两个大脑部位。在制定急性多头蚴病的诊断时，应考虑李斯特菌病、鹿蝇病、肉孢子虫病和脑灰质软化症和脑脓肿。在所有情况下，仔细检查动物都是必不可少的，而不能仅仅依靠辅助检查（主要是脑脊液检查）的结果，因为除多头蚴病以外的疾病也可能导致这些检查结果的变化。治疗基于在动物全身麻醉下切除多头蚴囊肿；该方法的成功率非常高，尤其是在准确定位病变后。尽管如此，许多农民出于经济原因可能会选择宰杀那些适合上市的绵羊，而对那些状况不佳的绵羊进行安乐死。
