Computed tomography of thoracic lymph nodes in 100 dogs with no abnormalitiesin the dominated area

摘要

In dogs, reports on thoracic lymph nodes are lacking compared to abdominal lymph nodes.This report analyzed the position, number, size, shape, and homogeneity of thoracic lymphnodes (cranial sternal, cranial mediastinal, tracheobronchial, aortic thoracic, andpulmonary lymph nodes) using thoracic computed tomography (CT) images of 100 dogs withoutany lesions in the dominated areas of thoracic lymph nodes. The position and number ofintrathoracic lymph nodes could be observed in CT, consistent with macroscopic anatomicalstudies. It was difficult to set a clinical index associated with size using CT scans.Image findings that indicated abnormalities, such as circular shapes and non-uniform, maybe routinely found in dogs and may not be considered abnormal on CT scans.
