Meningoencephalocele and supernumerary ectopic limb arising from the occipital bone in a Jacob sheep lamb.

This report describes the clinical, computed tomography, and magnetic resonance imaging findings for a Jacob sheep lamb diagnosed with meningoencephalocele and supernumerary ectopic limb. Key clinical message: This case demonstrates the utility of tomographic imaging in diagnosing congenital malformations in sheep and can be used to assess the extent of the lesion. This may help to determine any viable treatment, or, as in the case presented here, determine that the extent of the lesion precludes surgical intervention.
