Pseudolipoma of the Glisson capsule

Last revised by Henry Knipe on 30 Nov 2022

Pseudolipomas of the Glisson capsule are an uncommon developmental anomaly where a piece of colonic epiploic fat becomes ectopically located within the liver capsule.

Radiographic features

CT
  • well-circumscribed fat attenuation (-20 to -70 HU) nodule at the liver surface

  • it can sometimes have soft tissue attenuation and can have a small peripheral calcification 3

MRI
  • well-circumscribed nodule at the liver surface that follows fat signal intensity on all sequences and suppresses with fat saturation

Differential diagnosis

They might be mistaken by peripheral intra-hepatic fat-containing lesions and, therefore, the differential diagnosis would include:

Other differentials considerations include:
