Intraosseous lipoma of the body of the sphenoid bone.

A case of intraosseous lipoma arising from the body of the sphenoid bone with intrasellar and suprasellar components is reported. This is the first report of this uncommon tumour occurring in an atypical intracranial site, producing the locally invasive and pressure effects of visual failure and hypopituitarism. The diagnosis was based on computed tomographic (CT) and magnetic resonance (MR) imaging with histological confirmation following frontal craniotomy.
