Differential Considerations
Osteoarthritis:
- Pyrophosphate arthropathy most commonly presents with imaging characteristics similar to OA with a specific distribution.
- Subchondral cysts in CPPD CDD are generally larger.
- OA in an atypical location (i.e.
radiocarpal joint,
elbow,
patellofemoral joint),
consider CPPD—even in the absence of chondrocalcinosis.
Septic arthritis and gout:
- Clinically,
this can be a difficult differentiation from pseudogout attack.
- Patients can present with fever and increased erythrocyte sedimentation rate in any of these processes.
- Joint aspiration with evaluation for crystals and bacteria is recommended.
