Plain-English summary
A 6-year-old spayed female Rottweiler weighing 43 kg was brought to the vet because she had been limping on her left back leg for a month. During the exam, the vet noticed swelling in her left knee joint and some instability. X-rays showed fluid in the joint and changes to the knee structure, along with an enlarged lymph node behind the knee. Surgery revealed thickening of the joint lining, and tests confirmed she had T-cell lymphoma, a type of cancer affecting the tissue around the joint. It's important to note that limping can sometimes be the only sign of lymphoma in dogs.
Abstract
A 6-year-old, 43-kg, spayed female rottweiler was presented for a 1-month history of progressive, left hind-limb lameness. Upon physical examination, a cranial drawer sign and joint distention were present in the left stifle. Radiographically, the stifle had evidence of effusion, remodeling of the patella, and an enlarged popliteal lymph node. Marked synovial thickening and an intact cranial cruciate ligament were noted during surgery. Despite finding a nonspecific, mixed inflammatory response on joint fluid cytopathology, histopathology demonstrated T-cell lymphoma of the synovium. Lameness may be the sole presenting clinical sign in canine lymphoma.
