Open spina bifida is an uncommon malformation in animals, and there is a lack of imaging, clinical, and pathological characterisation of this condition in dogs.
Open spina bifida is rarely observed in animals due to high levels of perinatal mortality and frequent euthanasia. To the best of our knowledge, we present the first case of spina bifida in a dog was diagnosed in-utero and then followed post-partum.
A 3-year-old Poodle was presented with twin pregnancy. Radiographic and ultrasonographic findings were suggestive of vertebral malformation and open spina bifida with myelomeningocele in one foetus. Conservative treatment was given but the puppy died 3 days after birth. Thereafter, anatomical and histopathological analysis of several organs was performed to characterise the disease.
When the twins were born, one puppy had a linear dorsal midline cutaneous defect extending from the level of vertebrae L2-L6. R Radiographic examination showed several congenital vertebral malformations involving the thoracic segment, lumbar segment, sacrum and scapula. Histopathological examinations confirmed the presence of open spina bifida and identified additional abnormalities in several internal organs.
This case presents a complete characterisation of open spina bifida, before birth and after death, using imaging and histopathology techniques.
开放性脊柱裂在动物中较为少见,目前有关犬开放性脊柱裂的影像学、临床和病理学特征的研究较少。
由于围产期死亡率高和频繁安乐死,开放性脊柱裂在动物中很少被观察到。据我们所知,我们首次报道了一例在犬子宫内诊断出的并随后在产后进行随访的脊柱裂病例。
一只 3 岁的贵宾犬被诊断为怀有双胞胎。放射学和超声检查结果提示一只胎儿存在椎体畸形和开放性脊柱裂伴脊髓脊膜膨出。给予保守治疗,但幼犬在出生后 3 天死亡。随后,对多个器官进行解剖和组织病理学分析以对疾病进行特征描述。
当双胞胎出生时,一只幼犬背部有一条从第 2-6 腰椎水平延伸的线性中线皮肤缺损。放射学检查显示多个涉及胸段、腰段、骶骨和肩胛骨的先天性椎体畸形。组织病理学检查证实存在开放性脊柱裂,并在多个内部器官中发现了其他异常。
本病例通过影像学和组织病理学技术,在出生前和死后对开放性脊柱裂进行了全面的特征描述。
