Ventral Slot Surgery for Management of Ganglioneuroma and IVDD in a Cat

Abstract

Abstract A Shorthair castrated 8-year-old tomcat was brought to a veterinary hospital for slowly progressive onset of tetraplegia developing within last 14 days. The clinical and blood examinations at admission showed no abnormalities, the neurological examination showed severe cervical pain and tetraplegia with lower motor neuron deficits on thoracic limbs and normal withdrawal with increased patellar reflexes on pelvic limbs. Deep pain perception was present on all four limbs. The neuroanatomic localisation was C6-T2 lesion. Magnetic resonance imaging of the cervical spine demonstrated severe spondylosis deformans, degeneration of multiple IVD, and ventral extradural right sided spinal cord compression at the level C7-T1. Mildly hyperintense on T2-weighted and STIR, mildly hypointense on T1-weighted pre-contrast, and homogeneously contrast-enhancing mass on T1-weighted post-contrast images was observed at this area. This article describes an interesting case of a tumor in a cat localised in the cervicothoracic spinal segment extradurally compressing the spinal cord and causing severe neurological dysfunction. These clinical symptoms were successfully treated through a ventral slot surgery, the tumor was well circumscribed and comfortably removable through this approach. This rare tumor is considered benign and prognosis is favourable after surgical removal due to its non-invasive growth pattern. After surgery, the cat was observed continuously for a few months and the recovery was sufficient with no recurrence of neurological symptoms by now. This case is worth attention mainly because, despite the serious clinical presentation, it has a good long term prognosis and does not require a complex surgical approach.
