What is your diagnosis? Cerebrospinal fluid from a sheep

In May 2011, 2 Sarda breed sheep (ID569 and ID622) from a livestock facility in the province of Nuoro (Sardinia, Italy) affected with chronic coenurosis were presented to the Veterinary Clinical Laboratory of the University of Sassari. The animals were included in a study conducted to investigate potential alterations of the brain and skull in 24 sheep with chronic coenurosis by magnetic resonance imaging (MRI). The MRI detected the presence of one cyst in the medial cerebral hemisphere of sheep ID569, and 2 cysts in the left cerebral hemisphere of sheep ID622. Definitive diagnosis of chronic coenurosis was made by macroscopic and morphologic identification of T multiceps cyst after surgical extraction. Both animals manifested depression, disorientation, and alterations of postural reactions. Sheep ID569 revealed bilateral menace deficit while sheep ID622 showed a unilateral menace deficit. Complete resolution of neurologic signs was observed in both sheep within 7 days after removal of cysts
