Most lipomatous lesions do not present any particular diagnostic problems; nevertheless, a group of fatty tumors, including infiltrating lipoma, pleomorphic lipoma, spindle cell lipoma, and lipoblastoma, may cause considerable diagnostic difficulties and may be mistaken for liposarcoma 2. Infiltrating lipoma is an uncommon mesenchymal neoplasm that characteristically infiltrates adjacent tissues and tends to recur after excision.
The gross appearance of the mass is that of an irregular, lobulated, firm fatty lesion with no evidence of encapsulation.
Consequently, the imaging features can be easily differentiated from those of fatty benign lesions but not from those of many types of soft-tissue sarcoma. American Journal of Neuroradiology Feb24 2. Myxoid liposarcomas, the most common variety of liposarcoma, and especially pleomorphic or round cell or dedifferentiated liposarcomas, contain little or no fat. Diffuse infiltration of entrapped striated muscles can be seen; no evidence of lipoblasts, cellular atypism, or mitoses indicating liposarcoma is seen.
