Figure 1 Four-phase computed tomography images. A: Computed tomography on arterial phase performed in May 2012 showing a 2.0-cm mass with central necrosis and peripheral solid portions; B: Computed tomography on arterial phase performed in November 2015 showing a partial response of the mass.

Figure 2 A chromosome study and fluorescence in situ hybridization study. A: Giemsa-banding karyogram at initial diagnosis: 46, XX, t(11;19)(q23;p13.1). The arrows indicate the involved chromosomes; B: Metaphase fluorescence in situ hybridization with the KMT2A probe revealed a red signal on the derivative chromosome 19, a green signal on the derivative chromosome 11, and a fusion signal on the normal chromosome 11.
