Use of 1% polidocanol and pre- and post-computed tomography for treatment of a suspected nasolacrimal duct cyst in a dog.

Objective: To describe the efficacy of the sclerosing agent 1% polidocanol in the treatment of a suspected nasolacrimal duct cyst in a dog.

Animal Studied: A 5-year-old castrated male Golden Retriever with chronic epiphora of the right eye.

Procedures: Ocular examination revealed epiphora and a negative Jones test of the right eye and was otherwise normal.

Intradural Dirofilariasis in a Dog with Chronic Cervical Pain.

A 7 yr old female spayed Yorkshire terrier was referred to the author's institute for a 5 mo history of recurrent cervical spinal pain. Neurologic examination did not reveal any deficits. Hematologic and serum analyses were within normal limits.

Magnetic resonance imaging, treatment and outcome of canine vertebral chondrosarcomas. Six cases.

Objectives: To report the clinical presentation, magnetic resonance imaging features, treatments and outcomes of canine vertebral chondrosarcoma.

Materials And Methods: Retrospective review of medical records of dogs with confirmed vertebral chondrosarcoma and magnetic resonance imaging of the lesions, from four different veterinary referral institutions.

Results: A total of six dogs were included in this report.

Ventricular pneumocephalus, cervical subarachnoid pneumorrhachis, and meningoencephalitis in a dog following rhinotomy for chronic fungal rhinitis.

Case Description: A 5-year-old 35.8-kg (78.8-lb) neutered male Labrador Retriever was evaluated for chronic nasal discharge associated with a fungal infection.

Comparative evaluation of the liver in dogs with a splenic mass by using ultrasonography and contrast-enhanced computed tomography.

Evaluation of dogs with splenic masses to better educate owners as to the extent of the disease is a goal of many research studies. We compared the use of ultrasonography (US) and contrast-enhanced computed tomography (CT) to evaluate the accuracy of detecting hepatic neoplasia in dogs with splenic masses, independently, in series, or in parallel. No significant difference was found between US and CT.

Clinical signs and results of treatment in cats with patellar luxation: 42 cases (1992-2002).

Objective: To describe clinical signs and results of treatment in cats with patellar luxation.

Design: Retrospective case series.

Animals: 42 cats in which patellar luxation had been diagnosed on the basis of results of palpation of the stifle joints.

Use of computed tomography for evaluation of lung lesions associated with spontaneous pneumothorax in dogs: 12 cases (1999-2002).

Objective: To evaluate use of computed tomography (CT) of the lungs, compared with conventional radiography, for detection of blebs and bullae associated with spontaneous pneumothorax in dogs.

Design: Retrospective case series.

Animals: 12 dogs with spontaneous pneumothorax.

Foramen magnum decompression for treatment of caudal occipital malformation syndrome in dogs.

A method for foramen magnum decompression (FMD) in dogs with caudal occipital malformation syndrome (COMS) and results for 16 dogs are described. In brief, a dorsal approach to the caudal portion of the occiput and arch of the atlas was made, and a high-speed drill was used to remove a portion of the occiput in the region of the foramen magnum and the dorsal aspect of C1. The meninges that were exposed were removed or marsupialized to surrounding tissues.

Four cats with fungal rhinitis.

Fungal rhinitis is uncommon in the cat and cases of nasal aspergillosis-penicilliosis have been rarely reported. Signs of fungal rhinitis include epistaxis, sneezing, mucopurulent nasal discharge and exophthalmos. Brachycephalic feline breeds seem to be at increased risk for development of nasal aspergillosis-penicilliosis.

External hydrocephalus in two cats.

External hydrocephalus describes an accumulation of cerebrospinal fluid (CSF) between the cerebral hemispheres and the overlying arachnoid membrane, rather than within the lateral ventricles. Two young cats with encephalopathic signs were diagnosed with external hydrocephalus, one via magnetic resonance imaging and one via computed tomography. Both cats had abnormally large, broad heads, with no evidence of open fontanelles.

Clinical evaluation and long-term follow-up of dogs having coronoidectomy for elbow incongruity.

A retrospective study was performed describing the clinical presentations, radiographic findings, and surgical outcomes of 17 dogs (18 elbows) following medial coronoidectomy for the treatment of elbow joint incongruity as a sole disease entity. Complete resolution of lameness was achieved in 100% of the cases. The mean radiographic arthrosis grade progressed in 70% of the cases.

Ultrasound evaluation of the parathyroid glands in two hypercalcemic cats.

Two parathyroid masses were identified using ultrasound in two hypercalcemic cats. The masses were identified as parathyroid adenomas on surgical biopsy. Both parathyroid masses contained hypoechoic regions with distal acoustic enhancement.

Radiographic findings in dogs with naturally-occurring primary hypoadrenocorticism.

Survey radiographs often are obtained in dogs with primary hypoadrenocorticism in adrenal crisis as part of the routine evaluation of a critically ill dog. In this study, standardized methods of cardiac, pulmonary vasculature, and vena cava mensuration were used in 22 dogs with naturally-occurring primary hypoadrenocorticism, and the findings were compared with those in 22 breed-matched, clinically normal dogs. Most (81.

Evaluation of dogs with digit masses: 117 cases (1981-1991).

Medical records of 117 dogs with digit masses were reviewed. Of 124 digit masses, 76 (61%) were malignant neoplasms, 25 (20%) were benign neoplasms, and 23 (19%) were pyogranulomatous inflammation. Of 29 digits with radiographic evidence of bone lysis, 24 (83%) were affected by malignant masses, whereas only 5 of 29 (17%) digits with radiographic evidence of bone lysis were affected by benign or pyogranulomatous masses.

Contrast-enhanced computed tomography and myelography in six horses with cervical stenotic myelopathy.

The cervical spines of 6 horses with cervical stenotic myelopathy (CSM) were examined using myelography and contrast-enhanced computed tomography (CECT). Histopathology of the spinal cord of these horses identified 10 neurologically significant compressive lesions. Myelography and CECT were both able to demonstrate all 10 spinal cord compressive lesions, but myelography falsely identified 2 sites and CECT falsely identified 1 site as compressive lesions of the spinal cord which were not supported by histopathology.
