In this study population, RDW did not seem to be associated with the presence of heart failure or CDVD.

We describe the ultrasonographic diagnosis of diplomyelia in a 40-day-old calf. The acoustic window was the lumbosacral junction, which, in cattle, corresponds to the L6-S1 intervertebral space and enables the evaluation of approximately 1 cm of the length of the spinal cord. Despite this limited length, this acoustic window yields good anatomic details and can be helpful in assessing anomalies of the caudal aspect of the spinal cord.

Herein, we describe a calf affected by cerebellar displacement and spina bifida, diagnosed by ultrasonography. A full-term, newborn female calf with paralysis of the pelvic limbs was examined. The dorsal skin at the sacral level contained a circular defect; this was subsequently diagnosed as spina bifida. Cerebellar displacement into the cervical vertebral canal was suspected because of the frequent association of these anomalies. Spinal ultrasound examination carried out at the level of the craniocervical junction allowed identification of herniation of the cerebellum, the caudal part of brain stem, and part of an occipital lobe into the cervical vertebral canal. The ultrasonographic diagnosis was confirmed as post mortem examination. This type of brain defect, associated with spina bifida, resembles the Arnold-Chiari malformation in humans. r
