Question

question 14 (mandatory) (1 point) listen which finding best differentiates hydroxyapatite deposition disease (hadd) from calcium pyrophosphate deposition (cppd) on imaging? a) hadd produces amorphous, cloud - like calcifications adjacent to tendons b) hadd typically involves the articular cartilage c) cppd deposits appear as dense, cloud - like periarticular calcifications d) cppd is most often extra - articular

Explanation:

• Hydroxyapatite deposition disease (HADD) is characterized by amorphous, cloud - like calcifications adjacent to tendons.
• Calcium pyrophosphate deposition (CPPD) typically involves articular cartilage (so B is wrong for HADD). CPPD deposits are usually more linear (not cloud - like as in C) and CPPD is often intra - articular (so D is wrong).

Answer:

A. HADD produces amorphous, cloud - like calcifications adjacent to tendons
