Osteolipomas, a type of intracranial lipoma with bone and fat tissue, commonly occur in the suprasellar region. Ossification is a frequent finding in these tumors, aiding in diagnosis.

Area of Science:

  • Neuropathology
  • Neuroradiology
  • Oncology

Background:

  • Osteolipomas are rare intracranial tumors characterized by central adipose and peripheral osseous tissues.
  • They typically arise in the suprasellar/interpeduncular region, distinguishing them from other lipomas.
  • Understanding their unique histology is crucial for accurate diagnosis.

Observation:

  • A case of a 34-year-old male with an osteolipoma is presented.
  • Diagnostic imaging included computed tomography (CT) and magnetic resonance imaging (MRI).
  • Surgical removal of the benign lesion was performed.

Findings:

  • The histopathology confirmed the characteristic features of an osteolipoma.
  • Ossification was noted, consistent with 42% of reported lipomas in this region.

  • Intracranial lipomas at other sites rarely exhibit ossification.

    • Implications:

    • Ossification is a common feature of suprasellar/interpeduncular lipomas.
    • Osteolipoma should be considered in the differential diagnosis of fat-intensity masses with calcification in this area.
    • Radiological and pathological correlation is essential for definitive diagnosis.
