Abstract

Summary

This case report describes the diagnosis and management of primary femoral nerve sheath tumours in two dogs. Both of the tumours were localised by electromyography (EMG) and magnetic resonance imaging (MRI), and were then surgically resected using a novel approach to the iliopsoas muscle via osteotomy of the ventral ilial wing. This approach should be considered when attempting surgical treatment of conditions affecting the iliopsoas muscle or the femoral nerve because it provides excellent exposure of these structures.
