Coenurus cerebralis in a bul in Northeastern Turkey clinical and pathological observations

In this case report, the pathological and clinical symptoms of Coenurosis-which was diagnosed on a simmental bull at the age of two from the region of Erzurum, brought to the clinic with the complaint of neurological symptoms- are aimed to investigate. During anamnesis, we reached the information of the implementations like injections of antibiotic (florfenicol), vitamin-B1 (thiamine) and glucocorticoid (dexamethasone), but these injections were not resulted as expected. In physical examination, neurological symptoms like rotating around itself, leaning the head to the left side, incoordination and ataxia were detected. During hematological investigation, stress leukogram depending on the injection of dexamethasone was observed. A transparent 7x5 cm sized cyst in the ventral region of brain’s left hemisphere was observed during necropsy. After the dissection of this cyst, there was a grey-white fluid including protoscolex and the formation of atrophy in brain due to this cyst was detected. During the histopathological examination, a severe level of neural necrosis and gliosis, a milder level of hyperemia in vessels and infiltration of perivascular mononuclear cell and the infiltration of eosinophil leukocyte and mononuclear cell in the close regions of the wall of the cyst were observed. As a result, although clinical coenurosis is quite rare in cattle, in this report coenurosis is detected in a bull. Therefore, veterinarians should consider the possibility of encountering this illness in feeder cattle, too.
