the synovial manifestation of osteopoikilosis (synosteopoikilosis). To our knowledge the combination of the two entities has received little attention in literature, although several case reports have described osteopoikilosis and its associations, synovial osteochondromatosis is also an association to bear in mind when evaluating intra articular and juxta articular calcifcations. As reported by Havitcioglu, (15) when osteopoikilosis is detected or suspected, lesions of fibroproliferative origin, should also be sought. When evaluating intraosseous and extraosseous calcifcations, synovial osteochondromatosis with osteopoikilosis is an association to bear in mind. When osteopoikilosis is detected or suspected, lesions of fibroproliferative origin should also be sought.
