The above images show the superficial and deep digital flexor tendons, inferior check ligament, and suspensory ligament. The sonogram is consistent with chronic tenosynovitis of the digital sheath with two villonodular masses in the distal meacarpal region. This projection is 22-30 cm distal to the accessory carpal bone of the left forelimb.

Ultrasound

Ultrasonographic examination of the proximal suspensory region of both forelimbs was carried out.

Right forelimb A sonogram of the right foreleg revealed normal superficial and deep digital flexor tendons, and inferior check ligament. The mid and distal portion of the suspensory ligament (interosseous muscle) body had a decreased echogenicity and some short random fiber alignment consisten with a mild chronic, mostly inactive desmitis.

The medial suspensory ligament branch showed mild enlargement, particularly at its insertion with a mild decrease in echogenicity throughout the length of the branch and short randomly aligned echoes scattered through the branch along with a fair amount of hypoechoic periligamentous soft tissue. The lateral branch was also somewhat hypoechoic with some short random fibers along the palmar aspect of the branch, again consistent with mild chronic inactive desmitis.

Left forelimb: A sonogram of the left foreleg revealed normal superficial and deep digital flexor tendons, inferior check ligament, and suspensory ligament body and branches. The digital sheath was moderately thickened in the palmar aspect of the distal metacarpal region and it had two hypoechoic villonodular masses, on the medial and lateral aspects of the leg. The superficial digital flexor tendon was slightly misshapened by the thickened digital sheath; howerver there were no adhesions between the superficial digital flexor tendon and the digital sheath.
