Sonographic findings in the anterior interosseous nerve syndrome.
This report details previously undescribed sonographic findings in the anterior interosseous nerve syndrome. Loss of muscle bulk, increased reflectivity, reduced perfusion on Doppler sonography, and lack of active contraction of the affected muscles were observed. These findings can aid in the localization of the pathologic process and in the exclusion of tendon rupture. Dynamic observation of muscle function and Doppler changes after exercise can also help identify the muscles involved. Both sonography and MRI may be useful in the evaluation of patients with the anterior interosseous nerve syndrome and other peripheral neuropathies.
