A presumed primary pericardial lymphoma was diagnosed in seven cats. Clinical findings at presentation included poor body condition, dehydration and dyspnoea. Thoracic diagnostic imaging was performed in six cases and revealed pleural effusion and a diffuse thickening of the pericardium. A cytological diagnosis of lymphoma was obtained in six cases; in four cases the diagnosis was confirmed at necropsy. Immunophenotyping was performed in six cases: three cases were classified as T-cell and three as B-cell lymphoma. Four cats did not receive any treatment. One cat received only prednisone and two cats received chemotherapy. Six cats lived 7-11 days, except for one cat that received a multi-drug chemotherapy protocol and was still alive at the time of writing (750 days after diagnosis). Primary pericardial lymphoma is a rare extranodal feline lymphoma that has never been described previously.
