Polyostotic lymphoma with vertebral involvement and spinal extradural compression in a dog.

A 10-year-old, male, mixed-breed dog that developed cervical pain and neurological deficits was diagnosed with primary lymphoma of the second cervical vertebra. The cervical lesion was not surgically resectable. A dorsal cervical hemilaminectomy was performed to provide temporary decompression. The dog had complete pain relief after surgery but was euthanized 6 weeks later with recurrent clinical signs and evidence of lymphoma in the right femur.

Isolated lepromatous conjunctivo-corneal granuloma in a cat from Italy

OBJECTIVE To describe a case of a conjunctivo-corneal mass in a cat associated with acid-fast bacilli. METHODS A 2-year-old female black European Short-Hair cat, living outdoors in a suburban environment in Italy, was referred for evaluation of a nodular, vascularized mass of 2 weeks duration. The mass involved the dorsal bulbar conjunctiva at the temporal canthus of OS and invaded the sclera and cornea. Routine ophthalmic and systemic examination, serologic testing, cytology and histology of the mass were performed. Mycobacterium specific polymerase chain reaction (PCR) of variable regions 1, 2 and 3 of the 16S ribosomal RNA (rRNA) gene was also performed. RESULTS Neutrophils, lymphocytes, macrophages and giant cells with intracytoplasmic acid-fast bacilli were seen on cytological examination. The histological examination confirmed the presence of a granulomatous lesion with acid-fast bacilli within macrophages. Bacteriological culture of the material from the lesion was negative for Mycobacterium spp. Mycobacterium 16S rRNA gene specific PCR was positive. A diagnosis of feline leprosy was made. The owners refused any treatment, and 1 year later the lesion was still present. CONCLUSIONS Veterinary ophthalmologists should be aware of conjunctivo-corneal leproma as an unusual symptom of leprosy.

Lateral patellar luxation in nine small breed dogs

The objective of this paper was to describe the clinical features, the management and the outcome of nine small breed dogs affected with lateral patella luxation referred during the period between January 2010 and December 2014. Patellar luxations were classified according to: breed, age, sex, weight, and grade of patellar luxation, as well as if unilateral or bilateral, and concurrent cranial cruciate ligament lesion. In affected dogs, surgical correction consisted in the combination of tibial tuberosity transposition and soft tissue procedure. Adjunctive condroplasty or trochleoplasty was performed as needing. The outcome was found positive after surgical management with low complication rate and complications have been easily managed with high success rate.

Dacryocystography in a cat with orbital pneumatosis.

A 2-year-old neutered male European short-haired cat was presented for a persistent discharge from the scar of previous left eye enucleation, performed 6 months prior by the referring veterinarian. A surgical exploration of the orbit was performed and retained nictitating membrane glandular and conjunctival tissues were removed. Eleven days later, the cat developed an orbital pneumatosis caused by retrograde movement of air through a patent nasolacrimal system and diagnosed by survey radiographic examination of the skull. Nasolacrimal system patency was assessed by dacryocystography performed by injection of iodinated contrast medium under pressure into the orbital cavity. Computed tomography dacryocystography confirmed the radiographic findings. The condition resolved following dacryocystography, possibly as an inflammatory response to the contrast medium. To our knowledge, this is the first case of orbital pneumatosis reported in a cat.

Percutaneous transilial pinning for treatment of seventh lumbar vertebral body fracture. A retrospective analysis of 17 cases.

OBJECTIVE To evaluate outcomes after percutaneous application of transilial pinning in dogs with seventh lumbar vertebral body fracture with concurrent lumbosacral luxation. METHODS We reviewed the medical records of dogs with seventh lumbar vertebral body fracture stabilized with percutaneous transilial pinning that were treated at our hospital between January 2000 and March 2014. Radiographic measurements were used for comparing craniocaudal and ventrodorsal displacement pre- and postoperatively. RESULTS Seventeen dogs met the inclusion criteria. The neurological status of the majority of treated dogs improved quickly, with immediate pain reduction after surgery. Implants were well tolerated throughout the application period and were removed at a mean time of 54.4 ± 9.2 days. One dog experienced a major complication (implant failure) and required surgical revision a week after the initial procedure. Minor complications included pin-tract inflammation, signs of back pain lasting five weeks and acute lameness after implant removal. Postoperative radiographic measurements showed shortening of the vertebral body and residual dorsoventral dislocation. Otherwise, functional recovery was good (5 of 17 dogs) to excellent (10 of 17 dogs) in the majority of the patients. CLINICAL RELEVANCE The use of two percutaneous transilial pins can be considered as treatment for the management of seventh lumbar fracture-luxation in dogs. Our modified stabilization technique is relatively easy to perform; less invasive on the soft tissues; and uses implants that are versatile, modifiable, and easily removable.

Congenital deformity of the distal extremities in three dogs.

Congenital limb deformities are very rare conditions and the knowledge about etiology, pathogenesis, clinical presentation and treatment is still poor. Moreover, many defects are still not reported in veterinary literature. This report documents clinical and radiographic findings in three dogs with congenital deformity involving the distal extremities. Case 1 was affected with bilateral aphalangia of the pedes, case 2 presented a combination of brachydactyly and syndactyly, whereas in case 3 a unilateral ectrodactyly was observed. To the authors’ knowledge, brachydactyly, as well as aphalangia, are very uncommon anomalies and have been rarely documented. Moreover, association between syndactyly and brachydactyly has still not been reported.
