Preserved limb function following subtotal iliopsoas muscle and femoral nerve resection in a dog with low grade intramuscular chondrosarcoma.

Abstract

A 9-year-old spayed female Labrador retriever dog was diagnosed with a grade 1 chondrosarcoma associated with the right iliopsoas muscle. A computed tomography scan of the patient revealed the mass to begin at the level of L5, continuing to the insertion of the iliopsoas muscle on the femur. Surgery was performed to remove the mass. The femoral nerve was encased within the mass and the nerve was transected and removed, along with the iliopsoas muscle, with minimal intraoperative complications. With regular physiotherapy, the patient was able to independently walk, run, and jump, with mild functional lameness after 6 months.
