Diagnosis
Pre-sacral Liposarcoma
Note
45-year-old female presenting for chronic pelvic pain. There is a heterogeneously enhancing well circumscribed T1 hyper- and hypointense ovoid lesion arising in the pre-sacral space with regions of the lesion demonstrating loss of signal on the out of phase images, diffusion restriction, and heterogeneously enhancing. Imaging findings are compatible with a liposarcoma. Other fat containing pre-sacral lesions include peripheral nerve sheath tumor and dermoid. This lesion was surgically resected and found to be a liposarcoma. Liposarcoma typically arise in adults between the ages of the 40 and 60 years. Typical locations include the extremities or retroperitoneum. Primary surgical treatment is with wide local excision.
