Magnetic resonance imaging plays a relevant role in the assessment of patients with pain on the dorsal aspect of the distal forearm and wrist. Among the causes of pain, intersection syndrome is highlighted, corresponding to an inflammatory process affecting the tendons of the second compartment of the forearm extensor (extensor carpi radialis brevis and extensor carpi radialis longus), usually caused by direct trauma or repetitive activities requiring wrist flexion and extension. The present essay is aimed at illustrating the typical findings in intersection syndrome of the forearm and discuss the main differential diagnoses.
