Signs of metastatic disease on thoracic radiographs of dogs suffering from mammary gland tumours: a retrospective study (1990–1998)

Abstract: A mammary gland tumour (MGT) was clinically diagnosed in 136 dogs. Histologically 71% were malignant and 29% benign. Intrathoracic metastatic disease was noted or suspected radiographically in 13.5% of the dogs with malignant and in 2.5% of the dogs with benign MGT. Six dogs with malignant MGT were necropsied, 5 had pulmonary metastases but only 1 had radiographic signs of intrathoracic metastatic disease. We conclude that radiographs are not very sensitive for detection of early intrathoracic metastatic disea… Show more

“…CT allowed detection of metastases in two cases in the present study, thus showing greater precision than the plain radiographic examination that it is considered less sensitive for detection of small lesions [7,8,16,27]. In a retrospective study of 18 dogs with pulmonary metastatic neoplasia, the smallest size to detect pulmonary nodules on CT images was 1 mm, compared with 7-9 mm on radiographs [8].…”
