Use of a telovelar approach for complete resection of a choroid plexus tumor in a dog.

Objective: To describe a telovelar approach to the fourth ventricle for excision of a choroid plexus tumor within the ventricle.

Animal: A 3-year-old entire male Chihuahua.

Study Design: Case report METHODS: A 3-year-old dog with two-month history of progressive vestibular signs and subdued mentation was diagnosed with a fourth ventricle tumor.

Evaluation of concurrent analysis of cerebrospinal fluid samples collected from the cerebellomedullary cistern and lumbar subarachnoid space for the diagnosis of steroid-responsive meningitis arteritis in dogs.

Objective: To evaluate whether concurrent analysis of CSF samples from 2 collection sites (cerebellomedullary cistern [CMC] and lumbar subarachnoid space [LSS]) versus only 1 site could improve the diagnostic sensitivity of CSF analysis for dogs with suspected steroid-responsive meningitis arteritis (SRMA).

Animals: 111 client-owned dogs with SRMA diagnosed at 3 veterinary referral hospitals between 2011 and 2017.

Procedures: Only dogs with CSF collected from both sites (CMC and LSS) and with no previous history of corticosteroid administration were included.

Thoracic vertebral canal stenosis due to articular process hypertrophy in two cats treated by hemilaminectomy with partial osteotomy of the spinous process.

Case Summary: A 9-year-old neutered female British Shorthair cat (case 1) and a 13-year-old neutered male domestic shorthair cat (case 2) showed signs of chronic T3-L3 myelopathy, which progressed over 6 and 12 months, respectively. On presentation, case 1 had moderate pelvic limb proprioceptive ataxia and ambulatory paraparesis, and case 2 was non-ambulatory paraparetic and had urinary incontinence. Bilateral enlargement of the articular process joints at T11-T12 in case 1 and T3-T4 in case 2 causing dorsolateral extradural spinal cord compression was shown on MRI.

Uncommon acute neurologic presentation of canine distemper in 4 adult dogs.

Four uncommon cases of canine distemper (CD) were diagnosed in vaccinated adult dogs. All dogs had acute onset of neurologic signs, including seizures, abnormal mentation, ataxia, and proprioceptive deficits. Polymerase chain reaction for CD virus was positive on cerebrospinal fluid in 2 cases.
