Clinical and radiological features of anterior mediastinal lymphosarcoma in the cat: a reveiw of 30 cases.

The clinical and radiological features of 30 cases of anterior mediastinal lymphosarcoma in the cat are described; they represented 48 per cent of all cases of lymphosarcoma recorded at the University of Bristol Veterinary School between 1972 and 1977. The condition principally affected young cats and there was a predisposition in oriental breeds. Dyspnoea and regurgitation were the two most common major presenting signs. Diagnosis was made in most cases on the basis of radiological examination, but in some cytological examination of the thoracic fluid was necessary for confirmation.
