Objective:
The objective of our article was to highlight the important clinical and radiographic features of camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome. In particular, we emphasize those features that allow differentiation of CACP syndrome from juvenile idiopathic arthropathy.
Conclusion:
CACP syndrome should be considered in all patients who present with a noninflammatory arthropathy or with "atypical juvenile idiopathic arthritis," particularly if radiographs reveal an absence of erosions. In the correct clinical setting, large acetabular cysts on pelvic radiographs may be considered pathognomonic of CACP syndrome.
