Positional Change of Hepatic Pseudolipoma: a Case Report

Abstract

Pseudolipoma of Glisson’s capsule is a rare benign fatty mass that develops in the subcapsular space of the liver, typically at the interface between the diaphragm and the liver. Histologically, it resembles an epiploic appendage. This report describes a case in which a newly formed hepatic pseudolipoma migrated during follow-up. Positional changes in pseudolipomas are exceedingly rare, with only one other case documented in the literature. This case supports the hypothesis that a lipomatous mass originating from an epiploic appendage can migrate between the serosa of the liver and Glisson’s capsule, eventually forming a pseudolipoma. We present this case to provide valuable insights into the limited literature on this rare phenomenon.
