Computed axial tomography (contrast phase). (a) Sagittal section shows an increase in soft tissue volume in the mammary region of the L4 vertebral body. A hypodense lesion with continuity loss is seen at the posterior vertebra wall suggestive of erosive injury (arrow). (b) Cross section at the abdomen shows the spleen with granular characteristics and heterogeneity of its content. (c) In the thorax, abundant granular tissue is observed not only at the rib cage but also in the anterior and posterior mediastinum, secondary to the substance dissemination and infiltration.
