The left kidney was compressed and displaced to the inferolateral position (Figure 1). 
Axial CT with oral and IV contrast shows an unenhanced hypodense mass with well-defined borders in the anterior part of the spleen. Multiple round daughter cysts are seen peripherally within the lesion.

It had well-defined borders and contained multiple, round, daughter cysts in the periphery of the lesion (Figure 2).
Axial noncontrast T1-weighted MRI shows multivesicular splenic cyst with low-signal-intensity.

T2-weighted MRI revealed a multiseptated cystic mass in the spleen which had a well-defined capsule, the mass showing no significant contrast enhancement, except some vague signal increase in the septal parts (Figures 3, 4, and 5). The hypointense rim sign, characteristic of hydatic cyst, was best seen in the T2-weighted sequence (Figure 5).
Axial contrast-enhanced T1-weighted MRI shows hypointense multivesicular splenic cyst showing no significant contrast enhancement, except some vague signal increase in the septal parts.

T2-weighted MRI revealed a multiseptated cystic mass in the spleen which had a well-defined capsule, the mass showing no significant contrast enhancement, except some vague signal increase in the septal parts (Figures 3, 4, and 5). The hypointense rim sign, characteristic of hydatic cyst, was best seen in the T2-weighted sequence (Figure 5).
Coronal T2-weighted MRI shows multivesicular cystic lesion located in the middle and lower pole of the spleen, containing hypointense rim and septae.
