[Post-traumatic osteolysis of the distal end of the clavicle. Contribution of MRI]

The authors describe a case of post-traumatic osteolysis of the clavicle. The clinical and roentgenographic aspects are well known. But regarding the lytic X ray aspect, another diagnosis, particularly a tumor may be evoked. Scintigraphy and computed tomograms can take a part in the diagnosis. But scanograms are uneasy to do in this region. The MRI allows to delimit the lesion, and the hypointense signal in T1 and T2 weighted sequences directs to a fibrosis in the area between the end of the clavicle and the acromion. In this case report, the relation between the MRI findings and the pathological aspects was good.
