Presentation
Mobile painless mass of the upper dorsal region.
Patient Data
There is a well-encapsulated soft tissue mass (4 x 8 x12 cm) of the upper dorsal region from D1 to D5 levels.
It displays a high signal intensity on both T1WI/T2WI, attenuated on suppressed fat sequences (T1 fat sat and T2 fat supressed sequence), containing multiple thin fibrous septations within (< 2 mm) without obvious enhancement seen on postcontrast sequences.
Case Discussion
MRI features of an upper dorsal region soft tissue lipoma. Differential diagnoses should include normal adipose tissue ( usually non-encapsulated fatty mass, indistinguishable from the adjacent subcutaneous fatty tissue) and liposarcoma (thick enhanced septa or local invasion of the adjacent structures).
