Variable ultrasonographic presentation of splenic lesions in VL. (A,B): large lesions with more clearly defined borders when compared to the surrounding healthy parenchyma. (C,D): small lesions that appear mildly hypoechoic in comparison to the surrounding parenchyma. (A,C) were taken with a convex probe, which is useful to better identify spleen dimensions and bigger lesions. (B,D) were taken with high-frequency linear probes, which are crucial, especially in the case of smaller lesions (D) that have a less defined echotexture, for which these probes offer increased detection sensitivity.
