Findings:

XRAY:
There is a soft tissue mass noted in the right hemipelvis.  Note the radiolucency within the soft tissue mass consistent with a fat/adipose.


MRI:
A large mass within the right gluteal musculature posterior and lateral to the right hip. This mass measures approximately 16.8 cm in height x 11.5 cm in width x 12.8 cm in depth. It is well marginated and shows high intensity T1, high intensity T2, and low intensity T2 and proton density fat sat characteristics. Thus, this is indicative of an adipose-based neoplasm. The postcontrast images show mild amount of peripheral enhancement surrounding the lesion and small amount of intrinsic enhancement of its blood vessels, but the actual tissue does not enhance.

Diagnosis:

Large fat based mass noted on xray and MRI consistent with a large LIPOMA.
