Coenurosis is a central nervous system disease of wild and domestic ruminants caused by Coenurus cerebralis, a bladder worm stage of Taenia multiceps). Even in Sardinia island, this metacestode seems to be widespread in sheep (Scala et al. Vet Parasitol 143(3–4):294–298, 2007) where coenurosis is an important health problem (Varcasia et al. Parasitol Res 99(5):622–626, 2006) the last and unique report of coenurosis in cattle was in 1990 (Cubeddu et al. 1990). In the present paper, a case of bovine coenurosis in Sardinia was described 22 years after the first report with a morphological a biomolecular characterization. A 2-year-old Limousine bull was euthanized in the Bolotana (NU) municipality (Central Sardinia). The remote anamnesis achieved from the farmer reporting that the bull showed neurological symptoms from 1 year of age previously classified as nutritional problems by the farm’s veterinary. The breeder also says that the bull have by self-produced the skull fracture by hitting a gaff in the farm. The skull was opened and the brain removed and carefully examined showing two coenurus cysts containing clear fluid with numerous scoleces both in the right hemisphere. Morphological features of the cysts and mt-DNA sequencing confirm that the parasites were T. multiceps Coenuri.
