MRI features of intersection syndrome of the forearm.
OBJECTIVE
The purpose of this original report is to describe the MRI findings in patients with intersection syndrome of the forearm.


CONCLUSIONS
Intersection syndrome is an overuse disorder of the dorsal distal forearm, presenting with particular symptoms and signs that may be clinically misdiagnosed. MRI can perform an important role in establishing the diagnosis. Peritendinous edema (peritendinitis) around the first and second extensor compartment tendons, extending proximally from the crossover point, is the most characteristic finding that should suggest a diagnosis of intersection syndrome. Chronic cases may be subtle and not show substantial MRI findings likely reflecting the development of a stenosing tenosynovitis.
