case_images: At his second clinic visit at the age of 6, subtle symptoms consisting of swelling of interphalangeal, metacarpophalangeal and knee joints without stiffness observed (Figures 4G and H). The radiological findings were an increased anteroposterior diameter of the vertebral bodies, irregular vertebral end-plates and a slight enlargement of the metaphyses in the distal femurs, proximal tibiae, phalanges and metacarpals (Figures 4I-K).
