Abstract
This case report describes a dog with an infiltrative intramuscular lipoma in the
antebrachium, presenting with chronic left forelimb lameness and altered posture of
the digits. Computed tomography showed a fat-attenuating mass displacing the flexor
tendons. The mass was surgically excised along with the affected muscle belly and
tendon; histopathological examination revealed infiltration of adipose tissue cells
within the muscle belly and tendon sheath of the deep digital flexor muscle. After
removal of the lipoma, lameness resolved, full ambulatory function returned, without
recurrence at 1 year follow-up.
