Intracerebral fibroma: light and electron microscopic study

Area of Science:

• Neuropathology
• Surgical Pathology
• Electron Microscopy

Background:

• Intracerebral masses require accurate histopathological diagnosis for appropriate management.
• Distinguishing between neoplastic and non-neoplastic lesions is crucial.
• Rare tumors pose diagnostic challenges, necessitating advanced techniques.

Observation:

• A surgically excised intracerebral mass was analyzed using light and electron microscopy.
• Initial intraoperative diagnosis suggested meningioma.
• Ultrastructural examination provided critical diagnostic information.

Findings:

• Electron microscopy definitively excluded meningioma and intracerebral schwannoma.
• The findings substantiated a rare diagnosis of intracerebral fibroma.
• This case adds to the limited literature on true intracerebral fibromas.

Implications:

• Highlights the importance of ultrastructural analysis in diagnosing rare brain tumors.
• Emphasizes the need to consider uncommon diagnoses even when initial findings suggest otherwise.
• Contributes to the understanding and classification of rare central nervous system neoplasms.
