We describe the imaging procedures for the diagnosis of manubriosternal joi
nt arthritis in a 64 years old man with psoriatic arthritis. Involvement of
the manubriosternal joint (synchondrosis sternalis) in psoriatic arthritis
is a rare manifestation. The findings of bone-scintigraphy, conventional r
adiography and arthrosonography of the manubriosternal joint arthritis are
compared and discussed.
