MR and CT findings in a case of hibernoma of the thigh extending into the pelvis

Eur Radiol. 1998;8(3):476-8. doi: 10.1007/s003300050419.


Review of the literature shows no report of hibernoma of the thigh extending into the pelvis. Herein we report a case of hibernoma which appeared on CT and MR as a well-defined pelvic mass with contrast enhancement extending through the obturator foramen into the thigh. Fat was demonstrated by CT, whereas MR, using multiplanar sections, better analyzes the extension of the mass. This case demonstrates that hibernoma as liposarcoma can extend through the obturator foramen. However, no definite diagnosis could be made by CT or MR and the tumor must be considered as a "potential" malignant liposarcoma.
