Background: Hibernomas are rare benign soft-tissue tumours arising from brown fat tissue. Although imaging
characteristics are not specific certain imaging features, common locations and patient demographics may suggest
hibernoma as a differential diagnosis.
Case presentation: We report on two 48-year-old male patients with hibernoma. The tumour presented with local
swelling of the inguinal region in the first patient and was an incidental imaging finding in the second patient. Imaging
included magnetic resonance imaging in both patients and computed tomography as well as 18 F-fluorodeoxyglucose
positron emission tomography-computed tomography in the second patient. In both cases histological diagnosis was
initially based on excisional and needle core biopsy, respectively. Complete surgical resection confirmed the diagnosis
of hibernoma thereafter.
Conclusion: In soft tissue tumours with fatty components hibernoma may be included into the differential diagnosis.
Because of the risk of sampling errors in hibernoma-like tissue components of myxoid and well-differentiated liposarcoma,
complete resection is mandatory. This article also reviews the current imaging literature of hibernomas.
