A 9-year-old neutered male Wire Fox Terrier presented with an 1-month history of hindlimb paresis. Magnetic resonance imaging revealed a contrast-enhanced mass at the level of the L2 vertebral canal. The dog became paraplegic with no deep perception of the hindlimbs, and the mass was surgically removed. The histopathological diagnosis was of a malignant peripheral nerve sheath tumor (MPNST). The dog suffered a relapse of right hindlimb ataxia at 225 days after the surgery. The dog died 434 days after the surgery. Necropsy found a large mass in the abdominal cavity invading from the L2-nerve. This is the first report of MPNST invading the abdominal cavity through the nerve root.

A 7-year-old cat was referred with pelvic limb ataxia. Radiography and CT revealed bone resorption of the L1 vertebral arch, and myelography identified a compressive extradural lesion. The mass was surgically removed and histopathologically diagnosed as giant cell osteosarcoma. Three years later, the recurrent tumor resection and vertebral fixation were performed. Six months later, vertebrectomy was performed to radically excise the recurrent mass and a titanium spinal cage was placed. The cat is alive approximately 5 years after the first surgery. This case report describes vertebrectomy and vertebral body replacement as a radical treatment for feline vertebral osteosarcoma.

An intact, male mixed-breed cat approximately 3 months of age was referred to Iwate University Veterinary Teaching Hospital with dysuria that developed after a traffic accident. At the initial visit, a cystostomy tube was placed as a temporal urinary diversion. Antegrade urethrography revealed severe stenosis of the intrapelvic urethra. A prepubic urethrostomy (PPU) with formation of a convex urethral stoma was performed 22 days after the first visit. Twenty-four months after surgery, the cat could urinate smoothly in a standing position, although a small amount of intermittent leakage was observed immediately after getting up. There was no evidence of peristomal dermatitis. Therefore, the formation of a convex urethral stoma may effectively prevent peristomal dermatitis in cats who undergo PPU.

Thoracolumbar intervertebral disk herniation (TL-IVDH) with caudal articular process anomalies has been reported in Pugs. It currently remains unclear whether congenital caudal articular process aplasia/hypoplasia predisposes to the development of TL-IVDH. However, there are difficulties in proving the causal relationship between caudal articular process anomalies and TL-IVDH. The aim of this study was to describe the prevalence of TL-IVDH at the vertebral space containing anomalous and normal caudal articular processes in Pugs. Fifty-seven pugs were eligible to be included in this study. Caudal articular process aplasia/hypoplasia affected 52/57 (91.2%) dogs. The caudal articular process anomalies were most frequently located between T10 and T13. Colocalization of caudal articular process aplasia/hypoplasia and TL-IVDH was detected in 11 dogs (19.3%). The prevalence of TL-IVDH at vertebral spaces containing abnormal caudal articular processes was 12.3%, whereas the prevalence of TL-IVDH at vertebral spaces containing normal articular processes was 2.4%. With the increase in the number of vertebrae with caudal articular process anomalies, the prevalence of TL-IVDH also increased. The results of this study suggested the prevalence of caudal articular process anomalies was high in Pugs. The caudal articular process anomalies could be associated with TL-IVDH. A large cohort is needed to prove the causal relationship between caudal articular process anomalies and TL-IVDH.
