This case study highlights retroperitoneal lipomas, benign tumors of fat cells, found incidentally during routine follow-up for chronic lymphatic leukemia. Ultrasonography proved effective for monitoring these slow-growing masses.

Area of Science:

Oncology
Radiology
Gastroenterology

Background:

Lipomas are benign mesenchymal tumors originating from adipocytes.
Retroperitoneal lipomas are rare and often asymptomatic.
Patients with chronic lymphatic leukemia may have an increased risk of developing lipomas.

Purpose of the Study:

To describe a case of retroperitoneal lipomas in a patient with chronic lymphatic leukemia.
To evaluate the role of ultrasonography in the follow-up of retroperitoneal lipomas.
To discuss the diagnostic imaging modalities for retroperitoneal lipomas.

Main Methods:

Case report of a patient with chronic lymphatic leukemia undergoing routine sonography.
Detailed sonographic examination including color Doppler imaging.

Keywords:

Lipomas Retroperitoneal masses Ultrasonography

Retrospective review of CT scans and confirmation with MRI.

Main Results:

Two well-defined, hyperechoic, oval-shaped retroperitoneal masses were identified.
No intralesional vascularization was observed on color Doppler.
Lesions showed slow growth over 4 years, consistent with lipomas.

Conclusions:

Retroperitoneal lipomas can be incidentally discovered in patients with chronic lymphatic leukemia.
Ultrasonography is a cost-effective and repeatable imaging modality for follow-up of retroperitoneal lipomas.
CT and MRI are essential for initial diagnosis, while ultrasound aids in monitoring.
