Cerebral coenurosis is the intermediary larval stage of Taenia multiceps, which affects intermediate hosts, particularly sheep and goats. In this report, gross and microscopic features of three scarce natural coenurosis cases, a one-year-old ram and two lambs of 7 month old from a flock are explained. At necropsy, numerous small cysts measuring 5 to 10 mm in diameter were observed on both cerebrum and cerebellum surfaces, likewise multiple deep parts of which. In histopathological examination of the neural tissue, severe tissue destruction, a distinct layer of Gitter cells formation around the cysts, neuronophagia, gliosis and perivascular infiltration of lymphocytes were observed. In this early stage of parasite life cycle, larval migration and destruction of tissue, also aggregation of glial cells around the cysts cause a loose connection between cysts and neural tissue.
脑多头蚴病是多头绦虫的中间幼虫阶段，可感染中间宿主，尤其是绵羊和山羊。在本报告中，解释了来自一群羊的1只1岁公羊和2只7月龄羔羊这3例罕见的自然多头蚴病病例的大体和微观特征。尸检时，在大脑和小脑表面以及深部均观察到大量直径为5至10毫米的小囊肿。在神经组织的组织病理学检查中，观察到严重的组织破坏、囊肿周围形成明显的格子细胞层、噬神经细胞现象、胶质细胞增生以及淋巴细胞血管周围浸润。在寄生虫生命周期的这个早期阶段，幼虫迁移和组织破坏，以及囊肿周围神经胶质细胞的聚集导致囊肿与神经组织之间的连接松散。
