Bir Buzağıda Vertebral Malformasyon ve Siringomiyeli

Holstein ırkı, bir aylık dişi bir buzağı doğuştan arka ayakları üzerinde duramama şikayeti ile kliniklerimi-ze getirildi. Buzağının vital parametreleri normaldi ancak ayakta duramamaktaydı (astazi). Palpasyonda, colum-na vertebralisin T10-L2 arasındaki prosesus spinosusları düzensiz hissedildi. Nörolojik olarak, bilateral duyusal tepkiler vardı ancak motor refleksler bilateral azalmıştı. Radyolojik muayenede, T10-L2 vertebral segmentlerin intervertebral aralıklarında düzensizlik, prosesus spinosuslarda sinostoz ve vertebral skoliyoz tespit edildi. Prog-nozun olumsuz olduğu düşüncesi hasta sahibine aktarılarak alınan izin sonrası buzağının ötenazisi gerçekleştiril-di. Nekropside T10-L2 vertebral segmentlerin processus spinosuslarında skoliyoz ve sinostoz ile birlikte kavitas-yon belirlendi. Spinal kanalda yaklaşık 6 cm’lik bir transversal genişleme ve kollaps görüldü. Bu bölgenin enine kesitinde 1cm genişliğinde kistik kavitasyon görüldü. Mikroskopik olarak foramen centrale bu kavitasyondan ayrıydı. Kavitasyonun iç yüzeyinde belirgin hücre yapısı ve yangısal infiltrasyon da yoktu. Klinik, radyolojik ve patolojik incelemeler sonucu olgumuzda spinal malformasyon ve siyringomiyeli tanısı konuldu.

Spinal Malformation and Syringomyelia in a Calf

A Holstein breed, female, one-month-old calf was presented to our clinic with the complaint of con-genital astasia on the hind limbs. The vital parameters of the calf were normal, but she was not standing steadily. In palpation, spinal processes of T10-L2 vertebral segments were felt as deformed. Neurologically, there were sensible reflexes, but motor responses were weak bilaterally. In the radiological examination, the irregular inter-vertebral areas, synostosis on the spinal process and vertebral scoliosis were remarked between T10-L2 segments. Informing the weak prognosis of the calf to the patient owner, she was euthanized after permission. At necropsy, synostosis together with mild scoliosis, and cavitation placed was observed in the spinal process of T10-L2. About 6cm a transversal enlargement and collapse were seen in the spinal canal. A cystic cavitation about 1 cm in width was identified in the trans-section of this area.Microscopically, foramen centrale was separated from this cavitation. There was no distinctive cell forming and inflammatory infiltrations in the internal surface of the cavitation. As a result of clinical, radiological and patho-logic examinations, spinal malformation and syringomyelia were diagnosed.
