Figure 6.5.4 Synovitis (Feline) MR
5y MC Domestic Mediumhair with right tho-
racic limb lameness. On radiographs of the
elbow (a,b), there is mild osteophyte forma-
tion (b: small arrow) and medial joint space
widening (b: open arrowhead), which is most
apparent on the craniocaudal projection. There
is marked distension of the elbow joint on MR
images (c–f). The synovial component of the
joint distension is predominant on enhanced
images (e: arrow), with the central low signal
representing joint effusion (e: arrowhead).
STIR hyperintensity is present in the distal
humerus (f: open arrow). A diagnosis of lym-
phoplasmacytic synovitis and synovial cell
(a) DX, LAT (b) DX, CC hyperplasia associated with degenerative joint
disease was made on biopsy.
