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:
metastases from lipid-containing tumors like a liposarcoma
Other differentials considerations include:
