Abstract

A 15 wk old male unilateral cryptorchid German shepherd dog weighing 18 kg was referred for a nonhealing cutaneous lesion dorsally at the level of the sacrum, urinary incontinence, and a deviated tail. MRI revealed spina bifida and meningomyelocele continuous with the skin surface. Surgical correction of the meningomyelocele involved closure of the open meningeal defect, transection of the abnormal spinal nerves to the skin surface, and closure of the skin defect with a good outcome. Histopathology confirmed a meningomyelocele. This case report describes the MRI findings, surgical procedure, and proposed pathogenesis of spina bifida and meningomyelocele in a dog.

摘要

一只15周龄、体重18千克的单侧隐睾德国牧羊犬雄性幼犬，因骶部水平背部皮肤损伤不愈合、尿失禁和尾巴偏斜前来就诊。磁共振成像（MRI）显示脊柱裂和脊髓脊膜膨出，并与皮肤表面相连。脊髓脊膜膨出的手术矫正包括封闭开放的脑膜缺损、切断通向皮肤表面的异常脊神经，以及封闭皮肤缺损，预后良好。组织病理学证实为脊髓脊膜膨出。本病例报告描述了一只犬脊柱裂和脊髓脊膜膨出的MRI表现、手术过程及推测的发病机制。
