There is a large well defined encapsulated mixed density (fat, fluid and dentiform calcification) midline retroperitoneal mass displaced pancreases anteriorly and inferiorly with encasement both of celiac trunk and SMA with no gross vascular invasion, the mass exert pressure effect on distal CBD with upstream dilation of both intra and extra-hepatic bile ducts, the mass shows no significant enhancement in postcontrast study.
Both kidneys and adrenal glands look normal to suggest fatty containing angiomyolipoma or adrenal myelolipoma respectively.
Uterine congestion and distended left gonadal vein are noted due to mass effect of the mass.
