Abstract

The standard diagnostic method of anterior interosseous nerve syndrome is the nerve conduction test. This method is sometimes impossible to perform because it is an invasive method making it overly painful for patients. Authors report a case of anterior interosseous nerve syndrome which was detectable with sonography and MR imaging. Loss of muscle bulk, increased reflectivity, and lack of active contraction of the affected muscles were observed in sonography. In MR imaging, the volume of affected muscles was reduced and the signal intensity of the muscles was increased in T2WI and STIR. These findings are helpful not only for localizing the affected muscles but also for excluding the tendon rupture. Both sonography and MR imaging may be useful alteratives for diagnosing anterior interosseous nerve syndrome.
