CTICasesTophaceous Gout on Chest CT
Imaging findings
Chest CT shows abundant amorphous periarticular calcium about the sternoclavicular and glenohumeral joints, with classic periarticular erosions and gouty tophi, along with chondrocalcinosis. The hands show obvious severe gout.
Key takeaways
Florid tophaceous gout can be diagnosed incidentally on chest CT by amorphous periarticular deposits with classic well-corticated erosions and tophi at the sternoclavicular and glenohumeral joints. The distribution and appearance help distinguish it from mimics such as SAPHO syndrome, which affects the sternoclavicular joints but does not typically produce this degree of periarticular deposit.
