Pseudolipoma of the Glisson capsule is an uncommon developmental anomaly in which 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:
- hepatic lipoma
- hepatic adenoma
- focal hepatic steatosis
- hepatocellular carcinoma
- metastases from lipid-containing tumors like a liposarcoma
- lipopeliosis
- pseudocyst of the Glisson capsule
Other differentials considerations include:
