Aims and objectives
To illustrate multiple lipomatousmasses using MRI and CT imaging modalities,
pointing out the meaning of the nonlipomatous components in order to differentiate between lipoma and adipocytic tumors. To determine the significant findings in patients with lipomatous tumors and help to clarify the best features to indicate prognosis in cases with adverse clinical behavior.
Methods and materials
The authors review the radiological spectrum of fat-containing tissue masses,
with emphasis on computed tomography,
magnetic resonance imaging with pathologic correlation and monitoring of clinical behavior. We retrospectively examined a database of CT and MRI examinations of performed studies in our institution over a period of 4 years.
In these review,
78 patients with lipomatous masses where found. CT and MRI interpretations with their corresponding pathology reports were correlated. We...
Conventional lipomas may contain a few thin septa.
they are homogeneously fatty masses (fig.
Bands of muscle fibers are also acceptable components of intramuscular lipomas.
Thickened or nodular septa (generally > 3 mm),
associated nonadipose masses,
prominent foci of high T2 signal,
and prominent areas of enhancement are all associated with increased risk of well-differentiated liposarcoma (fig.
2). A well-differentiated liposarcoma produces an image of a predominantly fatty...
Regarding the differences in treatment,
and long term follow-up,
it will be of major importance to distinguishconventional lipomas from well-differentiated liposarcomas.
Imaging plays an important role in the diagnosis,
and response assessment of liposarcoma.
It will also be significant to remember that if the malignancy of the lession can not bedismissedby imaging techniques,
a biopsy should be performed.
