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 use the World Health Organization (WHO) classification for the soft tissue tumors (2013),
which divides lipomatous tumors into benign,
intermediate (locally aggressive) and malignant (table 1).
The MRI protocol included T1-weighted,
T2-weighted,
fat-suppressed/fluid-sensitive sequences and T1-weighted images after injection of contrast agent (Gadolinium) with and without fat suppression.
The images were assessed for the number,
site,
size and margin of the lesions,
as well as the signal intensity,
the internal architecture,
the effect on the surrounding tissue (edema,
neurovascular involvement) and the enhancement pattern.
When a fat-containing tissue mass does not satisfy the radiologic critera for lipoma,
there is a wide range of differential diagnosis,
including histological subtypes.
