Bilateral salivary adenocarcinoma with multiple metastases in a cat
Salivary gland tumors sometimes occur in dogs but they are very rare in cats. The patient described in this case report was presented with very unspecific clinical signs like coughing and dysphagia so that the diagnosis was difficult to do. Very informative case report from Italy.

A 9-year-old neutered male domestic shorthair cat was presented because of coughing, dysphagia, and prostration. Examination revealed firm bilateral anterocervical swellings extensively adhered to the surrounding tissues.

Anisocoria with left-side miosis was also evident.

X-ray and ultrasound examinations along with a fine-needle aspiration biopsy were performed.

Slides were stained with May-Grunwald Giemsa, and a diagnosis of salivary gland carcinoma was made. At surgery, the tumor was found to involve both submandibular salivary glands as well as adjacent lymph nodes and surrounding tissues.

The cat was euthanized and necropsy was performed.

The majority of tissues and organs examined histologically, including mandibular and retropharyngeal lymph nodes, soft palate, laryngopharynx and lungs, contained neoplastic cells whose appearance was consistent with adenocarcinoma.

Bilateral salivary adenocarcinoma has not previously been reported in cats, and extensive metastases are rare.

SMALL ANIMAL PRACTICE

Sonography vs percutaneous palpation to identify targeted thoracolumbar intervertebral disc spacesmembers
During minimally invasive spinal surgery, correct identification of the affected intervertebral disc space is critical. Percutaneous palpation is commonly used, but results may be unreliable. Fluoroscopy is the gold standard but can be cumbersome and exposes operators to ionizing radiation. Spinal ultrasound has been described in veterinary medicine and could be a feasible alternative. This prospective, methods comparison study mimicked a minimally invasive spinal surgery in 10 canine cadavers and compared the accuracy of ultrasound and percutaneous palpation for thoracolumbar intervertebral disc space identification, using fluoroscopy as the reference standard.
