Vingt-deux chiens avec un adénocarcinome des glandes anales ou un lymphome furent inclus prospectivement, avec 16/22 ayant des SLN augmentés lors de l’échographie. L’échographie fut utilisée pour déterminer la taille des SLN. Le but de la présente étude était d’évaluer des radiographies pour détecter l’augmentation de taille des ganglions sub-lombaires (SLN). Évaluation de radiographies pour la détection de lymphadénopathie sub-lombaire chez des chiens. Additional imaging such as ultrasound or computed tomography remains important to confirm or exclude sublumbar lymphadenopathy. Radiographic visualization should raise suspicion of neoplastic infiltration of SLN but lack of visualization does not exclude mild to moderate enlargement. Ventral displacement of the colon, a soft tissue opacity in the caudal retroperitoneal space and loss of conspicuity of the ventral margin of the iliopsoas muscle were radiographic findings significantly associated with identification ( P-values 21.5 mm) were consistently detected radiographically by observers with specialist imaging training. Sensitivity and specificity of radiographs for the detection of SLN enlargement were 81%/70%, 94%/81%, and 75%/100% for a general practitioner, imaging resident, and radiologist, respectively. Three blinded observers evaluated 43 right lateral abdominal radiographs for the presence of SLN enlargement. Twenty-one dogs without enlargement were retrospectively included as controls. Twenty-two dogs with anal gland adenocarcinoma or lymphoma were prospectively included, with 16/22 having SLN enlargement on ultrasound. Ultrasound was used to determine SLN size. The purpose of this study was to evaluate radiographs for the detection of sublumbar lymph node (SLN) enlargement.
