The pupillary light reflex and menace response in neonatal calves: the role of environmental isolation on development of the menace response. Clinical examination of the ruminant nervous system. Imaging diagnosis-Ultrasonographic diagnosis of diplomyelia in a calf. Testoni S, Grandis A, Diana A, Dalla Pria A, Cipone M, Bevilacqua D, et al. Congenital diplomyelia and hydromyelia in two calves. Hut P, Vos P, Hooijer G, de Neck S, Jurgens B. The aetiology of diplomyelia in calves remains unclear.Ītaxia & Pollakiuria Bunny-hop Calf Congenital diplomyelia Myelodysplasia Schmallenberg virus. This case report is of clinical and scientific importance as it demonstrates the possibility of a focal microscopic diplomyelia, which would not be evident by gross examination alone, as a cause of hind-limb ataxia. In particular, a 'bunny-hop' gait of the pelvic limbs is thought to be a specific clinical symptom of diplomyelia. This type of lesion should be included in the differential diagnoses when a calf is presented with a general proprioceptive ataxia of the hind limbs. To find out more, read our cookie policy.

This case report adds value to future clinical practice, as it provides a clear description of focal diplomyelia as a previously unreported lesion and details its diagnosis using advanced imaging and histology.

The calf tested positive for Schmallenberg virus antibodies, however this is not considered to be part of the pathogenesis of the diplomyelia. By means of histology, the calf was diagnosed with focal diplomyelia at the level of the fourth lumbar vertebra, a rare congenital malformation of the spinal cord. MRI revealed a focal dilated central canal, and mid-sagittal T2 hyperintense band in the dorsal part of the spinal cord at the level of the third to fourth lumbar vertebra. Prominent clinical findings included general proprioceptive ataxia with paraparesis, pathological spinal reflexes of the pelvic limbs and pollakiuria. The calf was presented to the Farm Animal Health clinic, Faculty of Veterinary Medicine, Utrecht University, with an abnormal, stiff, 'bunny-hop' gait of the pelvic limbs.
This case differs from previously reported cases in terms of localization and minimal extent of the congenital anomaly, clinical symptoms and findings during further examinations. Magnetic resonance imaging (MRI) images and histological findings of the affected spinal cord are included in this case report. This case report describes the clinical signs of a calf with focal diplomyelia at the level of the fourth lumbar vertebra.
