Diagnostic ultrasonography (A–D) shows an eccentric perivascular infiltration (arrowhead) at the level of bifurcation, with a soft intimal plaque (arrow) and a mild lumen narrowing without a hemodynamic change in Doppler mode. Follow-up ultrasonography (E) shows a marked decrease in the perivascular infiltration (arrowhead) and complete disappearance of the soft intimal plaque.
