This paper reports the first case of coenurosis in the State of Mato Grosso do Sul, Brazil. This disease is caused by the larval stage of the tapeworm Taenia multiceps (Leske, 1780). The animal in which the disease was diagnosed was an 18-month-old ewe from an endemic area of Southern Brazil as an imported animal among a group of 30 sheep. The clinic-pathological condition was that commonly found in herbivores affected by the disease, especially sheep. Apathy, nystagmus, intermittent blindness, circling and pressing head against obstacles were the neurological signs reported. The necropsy showed that a brain lesion in the subcortex of the right hemisphere was a bladder-like cyst measuring 4 cm in diameter filled with a translucent fluid with a large number of white spherules (protoscolices) floating. In addition to the identification of the Coenurus cerebralis protoscolices, the brain tissue lesion was histopathologically described.
