Femoral neuropathy in a dog with iliopsoas muscle injury.

OBJECTIVE

To report femoral nerve dysfunction caused by focal iliopsoas muscle injury and treated by performing tenectomy of the muscle insertion.

STUDY DESIGN

Case report.

ANIMALS

A 4-year-old, castrated male, English Mastiff.

RESULTS

Iliopsoas muscle injury caused femoral nerve deficits and severe pain. Focal injury was not detected by ultrasonography or computed tomography but was visible on magnetic resonance (MRI) images. Tenectomy of the insertion of the iliopsoas muscle relieved signs of pain.

CONCLUSIONS

Femoral nerve dysfunction may occur with iliopsoas muscle injury.

CLINICAL RELEVANCE

Iliopsoas muscle injury should be considered in patients with hip pain and MRI is a useful test for diagnosis. Tenectomy may be indicated for relief of chronic iliopsoas muscle pain.
