Radiographic Interpretation (Yanik DACVR, Illumipet.com): Abdominal study: Images 1 & 2: Marked splenomegaly strongly suspected to be secondary to torsion. Accompanying infiltrative or neoplastic pathology cannot be ruled out. Small volume of peritoneal effusion and/or inflammation likely secondary to the splenic pathology. Thoracic study: Images 3 & 4: Mild microcardia and underperfused pulmonary vasculature support of hypovolemia. Atypical intrathoracic fat distribution, which is consider incidental. Multiple hemivertebrae.

(Yanik DACVR/Lindquist DABVP): Images 5 & 6 demonstrate a canine spleen with mildly heteroechoic, moderately hypoechoic parenchyma, echogenic vascular walls, scalloping capsular contour and increased pericapsular fat echogenicity. Image 7 demonstrates complete lack of blood flow in the hilar vessels given the lack of color flow uptake over the anechoic vessel. Image 8 demonstrates minimal power Doppler uptake over the coarse and micronodular splenic parenchyma. Image 9: The free fluid associated with this presentation indicates either hemorrhage or transudate deriving from an infiltrative process. The video (Image 10) demonstrates a dilated splenic vessel with echogenic content in the far field likely indicating thrombosis given the complete lack of power flow uptake neither within the vessel nor the parenchyma.
