Posterior interosseous nerve (PIN) compression syndrome is a condition resulting from the compression of the deep branch of the radial nerve, which may lead to paresis or paralysis of the fingers and thumb. Anatomically, there are five potential sites for nerve compression in its course along the radial tunnel, the “Arcade of Fröhse” being the most usual. Clinically, patients start feeling pain in the lateral aspect of the elbow, which may be confused in the initial clinical diagnosis with lateral epicondylitis. The aim of this study is to present the case of a patient with clinical posterior interosseous nerve compression syndrome and to demonstrate that imaging studies can be used to localize and distinguish compressive neuropathy from other possible causes.
