Sacral intraosseous lipoma: a case report.

Sacral tumors are one of the most challenging lesions of the spine to study and manage. Surgical resection techniques are often difficult due to the regional anatomy, in addition to tumor involvement of neural and structural elements. The surgical goals are influenced by tumor pathology but this can be made more complicated by a difficult diagnostic process. The authors present the rare entity of a sacral lipoma and the radiological and histological features which highlight this condition.
