A six-year-old American Staffordshire terrier with proprioceptive deficits of the right thoracicand pelvic limb was referred for further work-up. Cervical computed tomography (CT)and magnetic resonance imaging (MRI) revealed a triple cervical canal stenosis with dorsal spinalcord compression and concomitant compressive myelopathy caused by vertebral arch andligamentum flavum proliferation and hypertrophy. Vacuum phenomena were noticed within theligamentum flavum tissue, a previously unreported location for vacuum phenomena, which areprimarily reported within degenerative joints and intervertebral discs. Decompressive surgeryand rehabilitation resulted in a complete clinical recovery.
