SUPRASELLAR OSTEOLIPOMA - CASE-REPORT

BACKGROUND Osteolipomas are distinguished from other intracranial lipo mas by their arrangement of central adipose and peripheral osseous tis sues and by characteristically arising in the suprasellar/interpeduncu lar region. METHODS We report computed tomography (CT), magnetic reson ance imaging (MRI), and pathology findings from this 34-year-old man w ho underwent surgical removal of this benign lesion. RESULTS This case displays the distinctive histopathology that has been reported in 13 of 31 (42%) lipomas in this region. In contrast, ossification of lipom as at other intracranial sites is relatively rare. CONCLUSIONS Ossific ation should be expected in many suprasellar/interpeduncular lipomas, and osteolipoma should be included in the radiologic differential diag nosis of fat-intensity masses with calcification in this region.
