  • Figure 1
    Radiographs of the right wrist
     

    Frontal view of the right wrist: on the distal epiphysis of the radius, scaphoid, trapezium, and proximal epiphysis of the first metacarpal bone several irregular ossified lesions are seen (see arrows).

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: Plain radiographic studies; Procedure: Diagnostic procedure; Special Focus: Dysplasias;

    Lateral view of the right wrist: also depicts the continuity of the epiphyseal and carpal lesions with the underlying bones (see arrows). Notice that the scaphoid and the trapezium are enlarged.

  • Figure 2
    MR of the right wrist
     

    T1-WI (coronal plane): in correspondence with the ossified excrescences demonstrated radiographically, several irregular lesions continuous with the bone marrow and cortex of the corresponding bones are shown (see...

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias;

    T1-WI (sagittal plane): the excrescences are made up of a osseous and a cartilaginous part (see arrows), the T1-WI adequately demonstrate the osseous component and the continuity with the underlying bone.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias;

    T2-WI (sagittal plane): the cartilaginous component of the lesions is hyperintense in T2 and is better depicted in this sequence (see arrows).

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias;

    T2-WI (axial plane): the osteocartilaginous carpal excrescences project to the joint and are associated with a small joint effusion (see arrow).
