case_images: It measured around 12.8cm x 7.7cm along the major transverse, anteroposterior and longitudinal axes, respectively (Figures 1 and 2), without any abnormalities in the abdominal cavity.  
case_images: The MRI show the extensive lobulated cystic components of the mass with low signal on T1WI (A) and high signal intensity on T2WI (B-D). Axial post-contrast image showed the solid septal component was significantly enhanced.
