This retrospective study describes the MRI features of extradural spinal neoplasia in 60 dogs and seven cats to identify potential distinguishing features between tumor classes and individual tumor types within each class. In dogs, mesenchymal tumors were most common (48%), with undifferentiated...

Background: Carcinomas are aggressive and invasive malignancies that originate from any type of epithelial cell and are responsible for many deaths in dogs. Carcinoma metastases occur primarily via the lymphatic route; however, they can occur by blood flow, thus reaching bone structures. In dogs,...

The aim of the study was to describe the signalment, clinical presentation and presumptive or final diagnoses of dogs with cranial thoracic spinal cord lesions identified on advanced imaging. Retrospective evaluation of the databases of three veterinary specialty centres, between 2009 and 2021, was ...

Background: The most common location of malignant tumors of the peripheral nerve sheath in the spinal cord is the intradural-extramedullary region, and is rare in the spinal nerve roots in the lumbar region. They mainly affect large female dogs over 6 years of age. Imaging tests assist in the...

Background: Intramedullary neoplasms of the canine spinal cord are infrequently reported. Objective: To describe distribution, clinicopathologic characteristics, radiographic findings, and clinical features of canine intramedullary spinal tumors. Methods: Retrospective series of histologically...

An 11-year-old spayed female Toy Poodle presented with acute tetraparesis. A small subcutaneous mass was found in the right trunk region, and the magnetic resonance revealed a compressive spinal cord lesion due to an irregular bone proliferation at the third cervical vertebra. After surgical...

The most common neurological spinal cord injury in dogs is between the third thoracic and third lumbar vertebrae (T3-L3). Using the PubMed database, a systematic review was designed to develop a diagnostic algorithm for the most frequent pathologies in this segment. The algorithm was created by...

An 8-year-old, Staffordshire bull terrier was referred for a progressive 8-week history of left pelvic limb paresis, postural reaction deficits, perineal hypoalgesia and lumbosacral pain. Magnetic resonance imaging revealed a L5-Cd1 circumferential T1-weighted isointense, T2-weighted/short Tau...

Meningiomas in dogs occur more commonly in the brain than in the cranial spinal cord. Intramedullary spinal cord tumours in dogs are described infrequently and present a diagnostic and therapeutic challenge. A nine-year-old Beagle dog was referred because of tetraparesis of a 20-day duration. The...

Various diseases can cause spinal cord disorders in dogs, including neoplasia of the nervous system, which are more common in mature and older animals. Some breeds, including brachycephalics, are more predisposed for certain types of tumours. Spinal neoplasia can be categorized as primary or...
