Purpose:
The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of hibernoma.
Materials And Methods:
We retrospectively evaluated imaging findings of CT and MR examinations of six patients (three men and three woman, aged 27-48 years) with histopathological diagnosis of hibernoma.
Results:
On CT examination, the lesions were slightly hyperdense, and on T1- and T2-weighted MR images, they were isointense or slightly hypointense compared to the subcutaneous fat. All of these lesions showed contrast enhancement and one out of the six lesions had internal linear septations.
Conclusion:
Hibernoma has a wide spectrum of CT and MR imaging findings, which should be considered in differential diagnosis, especially with other lipomatous lesions.
