An 8-month-old German Shepherd dog was presented for investigation of pelvic limb gait abnormality. Neurolocalization indicated a T3-L3 spinal cord lesion. The myelographic appearance was of an intramedullary lesion at T9/10, but upon subsequent magnetic resonance imaging it was determined that the mass was extramedullary. A diagnosis of nephroblastoma was made on histological examination. The imaging features of this rare tumor and the differentiation of intradural-extramedullary and intramedullary masses are discussed.
一只8个月大的德国牧羊犬因后肢步态异常前来接受检查。神经定位显示为T3-L3脊髓病变。脊髓造影显示T9/10水平有髓内病变，但后续磁共振成像确定肿块为髓外病变。经组织学检查诊断为肾母细胞瘤。本文讨论了这种罕见肿瘤的影像学特征以及硬膜内髓外和髓内肿块的鉴别。
