1. Core Imaging Pattern

• Osteoarthritis-like changes in atypical joints
• Symmetric distribution
• Non–weight-bearing joint predominance
• Frequent involvement of fibrocartilage and ligaments
• Calcification within cartilage or fibrocartilage (not on the surface)

---

 

2. Radiography / CT (Key Diagnostic Modalities)

• Chondrocalcinosis
• Joint space narrowing
• Osteophytes
• Subchondral changes
• CT

Wrist & Hand (Classic CPPD Pattern)

• Radiocarpal and scapholunate joints
• TFCC chondrocalcinosis
• Lunotriquetral ligament calcification
• Stepladder pattern of joint space narrowing
• STT (scaphotrapeziotrapezoid) arthropathy
• Advanced cases:

---

 

Knee (Most Common Site)

• Medial meniscus chondrocalcinosis
• Patellofemoral joint involvement
• Anterior femoral cortex scalloping at patellar level
• Osteoarthritis pattern disproportionate to age or loading

Radiologist’s Take-Home Message

CPPD arthropathy is a pattern diagnosis.
Calcification location, joint selection, and symmetry matter more than crystal visibility alone.
