title: B-mode and contrast-enhanced sonographic assessment of accessory spleen in the dog.
abstract: Four dogs with an accessory spleen are described. The accessory spleens appeared as a round-to-triangular structure located in the perisplenic area. They were homogeneous and isoechoic with the adjacent spleen. Contrast-enhanced ultrasound was performed using a second generation microbubble contrast medium (sulfur hexafluoride). The type and timing of enhancement of the accessory spleen was similar to that of the parent spleen. Contrast-enhanced ultrasound is a noninvasive modality useful in distinguishing an accessory spleen from a mass of another origin.
