The anterior inferior iliac spine and rectus femoris tendon appear rib-shaped with abnormal ossification and calcification of the right rectus femoris muscle tendon, representing anterior inferior iliac spine and rectus femoris tendon ossification.
Case Discussion
Ossification of the proximal origin of the right rectus femoris muscle from the anterior inferior iliac spine is suggestive of chronic tendinopathy or prior injury. If it is surrounding the joint it can cause a range of arthropathy, e.g. subspine impingement.
