Madelung's deformity (MD) is frequently associated with Leri-Weill's dyschondrosteosis (LWD) even if the primary isolated form (PI-MD) is much more common. Recent studies pointed out how two abnormal ligaments, the Vickers ligament (VL) and the radiotriquetral ligament (RTL), are defining traits of MD. To date, in PI-MD, both VL and RTL have been reported. In MD associated with LWD (LWD-MD), the VL is also present, but the RTL has never been reported. We herein report the first case of MD associated with a genetically confirmed LDW with an RTL, detected on MRI. This report describes the MRI imaging features of MD-LWD, which have not been adequately characterized in previous literature.
