Abstract

The present case report describes the workup of unilateral fibular-nerve-paresis in a female neonatal Fleckvieh calf. The calf was admitted to the Clinic for Ruminants with Ambulatory and Herd Health Services, Ludwig-Maximilians-University Munich as part of an investigation into a herd problem. The herd problem was presented as movement disorder in neonatal calves with an incidence of 10%. A physical, hematological, and musculoskeletal, as well as neurological examination was performed, and a diagnosis of a left-sided paresis of the fibular-nerve (N. fibularis) was made. Further special examinations including sonography, magnetic resonance tomography and muscle, lymph node, and nerve biopsies of the affected limb of the calf were also carried out. Advanced imaging examinations suggested the presence of inflammatory changes caudal to the left stifle joint in the region of the fibular nerve. Histopathological examination of the nerve biopsy confirmed the presence of a fibular-nerve-neuritis. Inflammatory changes in the ischiocrural-muscles were most likely injection-induced, consistent with the history of the veterinary practitioner and the examination results.
