ABSTRACT
Compression of the radial branch of the median nerve due to an anomalous muscle belly of the first lumbrical is a new diagnostic entity. We found this in the case of a 12-year-old girl with intermittent pain, weakness and paresthesias in the right hand. Provocative signs and symptoms in the distribution of only the radial branch of the median nerve are the most important signs distinguishing this case from carpal tunnel syndrome.
