We present a rare osteochondroma, which instead of being the usual exophytic growth outside bone, grew inward into the medullary cavity of distal femur in a patient with prior trauma to his knee. Except for its intramedullary location, the benign tumor had all the classic radiographic and pathologic features of typical osteochondroma.
我们呈现了一例罕见的骨软骨瘤，它不是通常在骨外的外生性生长，而是在一位膝关节既往外伤的患者的股骨远端髓腔内向内生长。除了其位于髓腔内的位置，该良性肿瘤具有典型骨软骨瘤的所有典型放射学和病理学特征。
