Resumo: 	5 歳6 カ月齢ホルスタイン種乳牛が，後躯麻痺による起立不能を呈した．浅頸リンパ節の腫大と直腸検査による腫瘤 の触知から牛白血病を疑ったが，血液検査とリンパ節の針吸引生検では確定診断できなかった．剖検では，60 × 40 × 20cm 大の多結節性腫瘤が背側の腹腔壁に接して存在していた．腫瘍組織は腸腰筋に浸潤し，一部は第5 および第6 腰 椎椎間孔より脊柱管内に連続的に波及し，脊髄および脊髄神経根を圧迫していた．腫瘍はCD3 陽性のT細胞性リンパ 腫で，牛白血病ウイルス抗体陰性であったため，散発型牛白血病と診断された． A Holstein cow (5 years and 3 months old) presented with hind limb paresis and was unable to stand. Bovine leukosis was suspected given the enlargement of cervical lymph nodes and existence of an abdominal mass detected by rectal palpation; however，it could not be confirmed by blood examination and fine needle aspiration of cervical lymph nodes. Pathological examination revealed a mu1tinodular mass (60 x 40 x 20 cm) on the dorsal abdomen that was invasive into the iliopsoas muscle. A portion of the mass invaded the vertebral canal between the 5th and 6th intervertebral foramina and compressed the spinal cord and nerves. Histopathological examination revealed the mass to be T-cell lymphoma based on CD3 positivity. Given that antibodies against bovine leukemia virus were not detected，the case was diagnosed as sporadic type bovine leukosis.
