Sixty cases of diaphragmatic hernia in dogs and cats were radiologically reviewed and categorized by their characteristic radiographic signs. Any particular predilection for age, sex, or breed was not observed. Liver, stomach and small intestine were more commonly herniated. At least two radiographs, at different angles, were required for a valid diagnosis, because some radiographic signs were not visible in a single radiographic view and more clearly detectable in two radiographic views. In addition to previously reported radiographic signs for diaphragmatic hernia, we found that the location of the stomach axis and the displacement of tracheal and bronchial segments were also useful radiographic signs.

The development of veterinary dentistry has substantially improved the ability to diagnose canine and feline dental abnormalities. Consequently, examinations previously performed only on humans are now available for small animals, thus improving the diagnostic quality. This has increased the need for technical qualification of veterinary professionals and increased technological investments. This study evaluated the use of cone beam computed tomography and intraoral radiography as complementary exams for diagnosing dental abnormalities in dogs and cats. Cone beam computed tomography was provided faster image acquisition with high image quality, was associated with low ionizing radiation levels, enabled image editing, and reduced the exam duration. Our results showed that radiography was an effective method for dental radiographic examination with low cost and fast execution times, and can be performed during surgical procedures.

The presence of a malignant mixed tumor, also known as a carcinosarcoma, in the salivary gland is very rare. Such mors, which are typically aggressive, are characterized by the presence of carcinomatous and sarcomatous components. 9-year-old neutered female domestic short-haired cat presented with swelling in the right mandibular lesion that had rapidly enlarged over the previous 3 weeks. Physical examination revealed a large, fluctuated and painless subcutaneous swelling that was associated with a firm mass. Radiographs of the head revealed a soft-tissue density that involved faint circular calcific opacity. Contrast-enhanced computed tomography revealed that the peripheral capsulated cystic area had a contrast enhanced region without bone lysis. The cat received a total excision of the mass and postoperative radiotherapy. Histopathological analysis of the mass revealed that it was a malignant mixed tumor. Metastasis to the lung was discovered 7 weeks later, at which time treatment was stopped.

This report explains typical radiographic features ofScottish Fold osteochondrodysplasia. Three Scottish Foldcats suffering from lameness were referred to theVeterinary Medical Teaching Hospital, Seoul NationalUniversity, Korea. Based on the breed predisposition,history, clinical signs, physical examination, and radiographicfindings, Scottish Fold osteochondrodysplasia was confirmedin three cases. Radiographic changes mainly includedexostosis and secondary arthritis around affected jointlesions, and defective conformation in the phalanges andcaudal vertebrae. The oral chondroprotective agents suchas glucosamine and chondroitin sulfate make the patientsalleviate their pain without adverse effects.
