Omental Well-Differentiated Liposarcoma: US, CT and MR Findings

Francesco Meloni et al. Int J Biomed Sci. 2009 Sep.

Abstract

Liposarcomas are the most common of sarcoma tumours, they are usually located in the lower limbs, retroperitoneum, or abdominal cavity; up to date, only a few cases of omental liposarcoma with different histotype have been described. We present a case of omental well-differentiated liposarcoma and discuss imaging findings on ultrasound, computed tomography, and magnetic resonance to differentiate omental liposarcomas from other abdominal tumour entities.

Keywords: computed tomography; liposarcoma; magnetic resonance; omentum; ultrasound.

Figure 1
Abdominal US scan revealed a hypomesogastric mass, characterized by two components: a solid portion and a second portion formed by multiple cystoid cavities.
Figure 2
Figure 2
CT scan showed an abdominal mass extended from the hepatic hilus to the pelvis; it was composed of fatty areas (−85HU) near the mesentery and a hyperdense (32HU) portion located dorsally.
Figure 3
Figure 3
MR examination performed before (A) and after (B) contrast administration with T1- and T2-weighted images and suppression of fatty tissue (C) confirmed an abdominal mass with a dorsally located multicystoid area surrounded by fat.
