Changes

For other types of lymphoma affecting dogs the clinical signs will demonstrate the anatomical site affected.

For other types of lymphoma affecting dogs the clinical signs will demonstrate the anatomical site affected.

'''Mediastinal''' forms will present with dyspnoea due to compression of the trachea and upper respiratory tract. Dysphagia may also be present due to compression of the oespohagus. Dogs with mediastinal lymphoma can also have pitting [[Oedema|oedema]] of the head and neck due to compression of the cranial vena cava. Reduced ‘rib-spring’ or compliance of the cranial thorax may be evident. On ausculatation there is often an absence of lung sounds cranially, and dullness on percussion of the cranial thorax and caudal displacement of the normal cardiac sounds. Polyuria and polydypsia may be present due to paraneoplastic hyperlcalcaemia.

Polyuria and polydypsia may be present due to paraneoplastic hyperlcalcaemia. Differential diagnoses for a cranial mediastinal mass are: thymoma, thyroid adenocarcinoma, a mediastinal abscess, or a branchial cyst.

'''Alimentary''' forms will present with signs of obstruction such as [[Vomiting|vomiting]], [[Diarrhoea|diarrhoea]], anorexia and thickened loops of intestine on abdominal palpation.

'''Alimentary''' cats will present with vomiting, diarrhoea, weight loss and anorexia.

'''Alimentary''' cats will present with vomiting, diarrhoea, weight loss and anorexia.

'''Mediastinal''' cats will present with respiratory signs and may be in respiratory distress. In general the same clinical signs as those of the dog with mediastinal lymphoma will be present.  

'''Mediastinal''' cats will present with signs of compression of structures in the cranial thorax. These include dyspnoea, coughing and tachypnoea due to compression of the trachea. Weight loss and regurgitation may also occur secondary to compression of the oesophagus. On auscultation lung sounds are displaced caudally and lung sounds are decreased ventrally. There may be a loss of compressability ('rib spring') over the cranial thorax. There may be pleural effusion present. Differential diagnoses for a cranial mediastinal mass are: thymoma, thyroid adenocarcinoma, a mediastinal abscess, or a branchial cyst.

'''Renal''' lymphoma also occurs in cats and affected animals will present with signs similar to [[:Category:Renal Failure|renal failure]].
