Cervical meningomyelocele, spina bifida, and hydrocephalus were diagnosed in a newborn miniature colt that was unable to stand and had a cystic mass in the caudal portion of the dorsal cervical region. Results of physical examination and ultrasonographic imaging of the brain supported the diagnosis of hydrocephalus. Results of radiographic evaluation of the vertebral column were consistent with spina bifida at C5-C6. Fluid aspirated from the cervical mass resembled CSF. Radiography of the cervical region after injection of iohexol into the mass revealed herniation of the spinal cord through a large bony defect, supporting the diagnosis of spina bifida and meningomyelocele. Meningomyelocele, spina bifida, and hydrocephalus are interrelated congenital anomalies in other species. Meningomyelocele should be suspected in foals that have neurologic abnormalities, especially if they have other congenital anomalies and a fluid-filled mass along the dorsal midline.
在一匹新生的小型马驹中诊断出颈椎脊膜脊髓膨出、脊柱裂和脑积水，该马驹无法站立，在颈背区域尾部有一个囊性肿块。体格检查和脑部超声成像结果支持脑积水的诊断。脊柱X线评估结果与C5 - C6处的脊柱裂一致。从颈部肿块抽出的液体类似于脑脊液。向肿块内注射碘海醇后进行的颈部X线检查显示脊髓通过一个大的骨缺损突出，支持脊柱裂和脊膜脊髓膨出的诊断。在其他物种中，脊膜脊髓膨出、脊柱裂和脑积水是相互关联的先天性异常。对于有神经功能异常的马驹，尤其是有其他先天性异常且沿背中线有充满液体的肿块的马驹，应怀疑患有脊膜脊髓膨出。
