📌 Acute Gouty Arthritis vs. Septic Arthritis

 

• Septic arthritis and crystal-induced arthritis can both result in a painful, swollen peripheral joint. 
• Acute gout can cause a high fever and leukocytosis and may be difficult to distinguish from acute septic arthritis.

 

✅ Septic Arthritis

It is difficult to differentiate gouty arthritis from septic arthritis based on imaging findings. 

However, lamellated synovial thickening patterns, bone marrow edema, and soft tissue abscess formation are more commonly observed in patients with septic arthritis than in those with gouty arthritis.

 

✅ Gouty Arthritis

• Even though the MR imaging findings of acute gouty arthritis are nonspecific, it should be considered as a possible diagnosis. 
• This is especially true when a large amount of joint effusion, irregular and nodular synovial thickening, and soft tissue edema are present. 
• Notably, these findings should be without subchondral bone erosion, bone marrow edema, or soft tissue abscess in the knee or ankle joint.
