Ultrasonography of sclerosing angiomatoid nodular transformation in the spleen

Figure 3 Conventional ultrasonography and contrast-enhanced ultrasonography findings of sclerosing angiomatoid nodular transformation in a 39-year-old man. A: A hypoechoic lesion (arrow) in the spleen; B and C: Color Doppler flow imaging shows branch-shaped and wire-like blood-flow signals inside and spot-shaped blood-flow signals in the periphery of the lesion; D: The lesion was enhanced in the branch-shaped diffuse pattern (15 s after injection); E: It presented heterogeneous lobular appearance when reaching its peak enhancement; F: Lots of septa inside the lesion; G: Surface of the lesion found during the operation.
