Digital radiographs showed a mobile, irregular, calcific opacity over the elbow joint (Figure 1A, Figure 1B).
Lateral digital radiograph shows a faint, mobile, irregular, calcific opacity superior to the coronoid process (arrow). [Powerpoint Slide]

Axial and coronal T2-weighted Fast Spin Echo images demonstrated an irregular low signal intensity anterior to the coronoid fossa and surrounded by fluid (Figure 2A, Figure 2B).
Axial T2-weighted fast spin echo (FSE) MR image demonstrates a focus of irregular low signal intensity (arrow) anterior to the coronoid fossa, representing an intra-articular body. This is made more conspicuous by the small joint effusion surrounding the loose body. [Powerpoint Slide]

The loose body is not as conspicuous on T1-weighted images (Figure 3A, Figure 3B), but these images do provide some supportive information as to the calcific nature of the loose body.
Coronal T2-weighted fast spin echo (FSE) MR image demonstrates a focus of irregular low signal intensity (arrow) anterior to the coronoid fossa, representing an intra-articular body. This is made more conspicuous by the small joint effusion surrounding the loose body. [Powerpoint Slide]
