Dynamic gadolinium-enhanced fat-suppressed T1-weighted MRI (chemical shift selective images) for remitting seronegative symmetrical synovitis with pitting edema.
A 75-year-old man suddenly suffered from polyarthralgia and pitting edema in his distal extremities. Laboratory tests revealed inflammation, negative rheumatoid factor, and positive B7 human leukocyte antigen typing. Severe synovitis was observed in dynamic gadolinium-enhanced fat-suppressed (DGEFS) T1-weighted images of his right hand. Our diagnosis was remitting seronegative symmetrical synovitis with pitting edema (RS(3)PE syndrome). He responded dramatically to low-dose corticosteroids, after which his synovitis remarkably improved as observed with DGEFS imaging. DGEFS imaging is useful for distribution of synovitis in patients with RS(3)PE syndrome as well as assessing the efficacy of treatment.
