Horseshoe abscess of the hand with rice bodies secondary to mycobacterium avium intracellulare infection

We present a case of an 80-year-old woman with rheumatoid arthritis who presented with 6  months of right hand and wrist soft tissue swelling, initially treated as a rheumatoid arthritis flare. MRI demonstrates the horseshoe abscess and after surgical irrigation and debridement with synovectomy, cultures demonstrated infection with mycobacterium avium intracellulare (MAI).
