SANT on the imaging. (a) CT: hypodense lesion with a 77 mm maximum diameter and calcifications in the context. (b) CT: centimetric accessory spleen. (c) MRI: lesion (6.3 cm x 8.2 cm) characterized by heterogeneous intensity, iso-hypointense in T1. (d) MRI: a signal hypointense of the lesion in T2 with a centrally scattered hyperintense signal on the fat saturated precontrast phase.

Computed tomography scan confirmed the hypodense lesion presence, with a 77 mm maximum diameter, and calcifications in the context (Figure 1(a)). In addition, a centimetric accessory spleen adjacent to the lower pole was detected (Figure 1(b)). T1 (Figure 1(c)), predominantly hypointense in T2 with a centrally scattered hyperintense signal on the fat saturated precontrast phase (Figure1(d)). The early arterial phase evidenced peripheral enhancement with central radial progression, on the late phase images.
