Learning objectives
Retroperitoneal liposarcoma:teaching points.
Learning the different imaging findings of retroperitoneal liposarcoma and their pathological correlation.
Background
Introduction
Primary retroperitoneal sarcomas represent a diverse,
rare entity,
of which liposarcoma is the most common,
1,2,3,4,5 representing approximately 35% of malignant retroperitoneal tumors in adults.
one
Liposarcoma is defined as a malignant retroperitoneal primary tumor derived from various elements of the primitive mesenchyme,
urogenital crest,
and embryonic remnants that may originate in any region that contains fatty tissue.1,2,3,5,6
Symptoms
The symptoms are related to the location and size of the tumor depending on the structures underlying it.

Clinical presentation
The usual age of...
Findings and procedure details
We present three patients with diagnosis of probable liposarcoma per image,
which was later confirmed by biopsy.
Conclusion
The retroperitoneal liposarcomas represent a varied entity with different forms of clinical and radiological presentation that sometimes delays the diagnosis and at the same time decreases the possibility to carry out the treatment of choice,
which alters the survival of the patient.
