A 12-year-old female spayed, Silken Windhound dog was presented with a 3-month history of lethargy and cervical and lumbosacral spinal pain. No significant abnormalities were noted on CBC or serum biochemical assays. Magnetic resonance imaging of the spine demonstrated a soft tissue mass within the ventral and right epidural space at the level of the L7 vertebra. During surgery, a pale brown mass was identified within the epidural fat. Cytologic and histopathologic examinations demonstrated that the mass was composed of adipose tissue and hematopoietic elements, consistent with a myelolipoma. The lumbosacral spinal pain resolved after surgery. Epidural myelolipomas are rarely reported in the human and veterinary literature.
一只 12 岁已绝育的雌性丝毛犬因嗜睡以及颈、腰荐部脊柱疼痛就诊，病程 3 个月。全血细胞计数和血清生化检查未见明显异常。脊柱磁共振成像显示 L7 椎体水平的腹侧和右侧硬脊膜外腔有软组织肿块。术中发现硬脊膜外脂肪内有一个浅棕色肿块。细胞学和组织病理学检查显示肿块由脂肪组织和造血细胞组成，符合骨髓脂肪瘤的特征。手术后腰荐部脊柱疼痛缓解。硬脊膜外骨髓脂肪瘤在人类和兽医文献中鲜有报道。
