Patient Data

Age: 50
Gender: Female

The liver is enlarged and has diffuse fatty infiltration with a well-circumscribed hepatic dome subcaspular nodule measuring about 13x10x6 mm, displaying a fat density with internal tiny soft tissue densities without post contrast enhancement consistent with pseudolipoma of Glisson capsule. Right renal simple cyst  ( Bosniak I) is also noted.

 

Case Discussion

Pseudolipoma of the Glisson Capsule was initially described by Rolleston in 1891. Pseudolipoma refers to an encapsulated lesion containing degenerated fat that is enveloped by a liver capsule. It is thought to represent a detached colonic epiploic appendix that develops a fibrous capsule and lodges in the peritoneal cavity. When this lesion is in proximity to the liver, it may become attached to the liver capsule. .
