A rare lipoblastic meningioma, a brain tumor with fat differentiation, presented atypically on CT scans. Histopathology confirmed this unusual meningothelial neoplasia, challenging initial diagnosis.

Area of Science:

  • Neuro-oncology
  • Pathology
  • Radiology

Background:

  • Meningiomas are typically slow-growing tumors arising from the meninges.
  • Adipose differentiation is an extremely rare feature in meningiomas.
  • Accurate preoperative diagnosis of rare meningioma subtypes can be challenging.

Observation:

  • A patient presented with a right parietal mass lesion.
  • Computed tomography revealed heterogeneous characteristics, including hyperdense contrast-enhancing and hypodense fat-density areas.
  • The lesion's unusual imaging features hindered definitive preoperative and intraoperative diagnosis.

Findings:

  • Histopathological examination was crucial for diagnosis.
  • The lesion was identified as a meningothelial neoplasia with adipose differentiation.

  • This specific subtype was characterized as a lipoblastic meningioma.

    • Implications:

    • Highlights the importance of histopathological confirmation for rare tumor variants.
    • Suggests that unusual imaging findings in meningiomas warrant consideration of rare subtypes.
    • Contributes to the understanding of meningioma heterogeneity and diagnostic challenges.
