title: Radiographic abnormalities in canine multicentric lymphoma: a review of 84 cases.
abstract: The thoracic and abdominal radiographs of 84 dogs with multicentric lymphoma were examined to identify the radiological abnormalities. The frequency of occurrence of individual changes, role of radiography in diagnosis, relationship of radiographic changes to hypercalcaemia and prognostic relevance of radiographic findings were assessed. Multiple abnormalities were more commonly seen than solitary changes. No radiographic abnormalities were seen in approximately one quarter of thoracic radiographs and one fifth of abdominal radiographs. Lymphoma could not be diagnosed on the basis of radiographs alone. Many of the features of lymphoma were non-specific, having numerous possible causes. Cranial mediastinal disease was neither a prerequisite for, nor a disproportionately common finding in, hypercalcaemic patients. The absence of radiological abnormalities may be a positive prognostic indicator for the individual patient. The differential diagnoses for the radiographic abnormalities seen in lymphoma are discussed.
