Imaging of a Rare Case of Gluteal Myxoid Liposarcoma

Myxoid liposarcoma is a distinct subtype of soft tissue sarcoma, characterized by a myxoid stroma, delicate capillary networks, and scattered lipoblasts. It has demonstrated a notable pattern of spread to soft tissue and bony structures. MRI examination is a highly reliable method in the diagnosis of these tumors. We report the case of a 61-year-old patient with a history of intra-abdominal liposarcoma of the right iliac fossa, surgically treated three years prior, who presented with a slowly enlarging, painless right gluteal mass evolving over one year, in whom magnetic resonance imaging played a pivotal role in the detection and characterization of the lesion, highlighting some imaging features of myxoid liposarcoma. Through this rare case, we review the imaging findings of myxoid liposarcoma and emphasize the value of MRI in the evaluation of soft tissue sarcomas.
