Une malformation artério-veineuse, une exostose bi-condylienne et un kyste synovial calcifié du coude : association ou coïncidence ?

Arteriovenous malformations of the upper limb are rare. Their usual location near the joints and their random association of anatomical variations and structural abnormalities make their surgery extremely difficult. Esthetic risks and functional requirements of surgical resections require a special management by an experienced surgeon. We report the case of a 20-year-old athlete, who had an original association or coincidence of an arteriovenous malformation located on the elbow and the forearm with an epicondylar and an epitrochlear exostosis associated with a calcified synovial cyst of the elbow. A surgical excision in two stages was undertaken with a good functional outcome and no significant disfigurement.
