Hibernoma is an uncommon lipomatous tumor composed of brown adipose cells that until recently has only ever been described in soft tissue locations. This report describes the histological features of a discrete lesion in the sacrum of an 84-year-old lady. Biopsy of this lesion demonstrated that it consisted predominantly of multivacuolated lipocytes with a morphological and immunohistochemical profile consistent with brown fat cells. The lesion was diagnosed as an intraosseous hibernoma. This is the 16th report in the English literature of a hibernoma occurring outside of a soft tissue location.

Lipomas of the talus are rare benign bone lesions. They are usually atraumatic in aetiology with a male preponderance and generally occur between the third and sixth decades of life. We report the case of a man in his 30s who had presented with pain and swelling in the posteromedial aspect of his left ankle of 6 months' duration, associated with functional restrictions, and was diagnosed as a case of intraosseous lipoma involving the talus.

Article Synopsis
- * An MRI showed specific signal characteristics in the lesion, initially suggesting it was an aneurysmal bone cyst.
- * A follow-up MRI conducted 3 years later indicated that the lesion had changed to predominantly contain fat, highlighting the transformation of an intraosseous lipoma over time.

Article Synopsis
- Intraosseous lipoma of the calcaneum is a rare condition that can cause significant heel pain, particularly in younger adults, with limited published cases.
- A 35-year-old woman experienced worsening left heel pain for a year, which was severe enough to impact her daily activities; she underwent surgery involving curettage and bone cement filling.
- Post-surgery follow-up showed no residual pain after 2.5 years, highlighting the need for orthopedic surgeons to consider this uncommon diagnosis and the effectiveness of surgical treatment when conservative methods fail.
