Summary:A 3-year-old female miniature dachshund presented with acute astasia for which magnetic resonance imaging(MRI) was performed. On neurological examination, the postural response and spinal reflex in the fourlimbs were abnormal. MRI revealed a mass in the C4-5 dorsal spinal region with hypointensity on T2-weightedimages and isointensity on T1-weighted images. After gadolinium enhancement, the mass was enhancedin the shape of a ring. Moreover, the mass extended to the surface of the body. Surgical resection of the masswas performed and its histological diagnosis was a dermoid sinus. From these findings, this case was diagnosedas a type Ⅳ dermoid sinus. This is the first report of a type Ⅳ dermoid sinus in a miniature dachshund.
