Pineal region meningiomas without dural attachment
Surgical Neurology
|February 1, 1982
Abstract:
A rare case of meningioma in the pineal region without dural attachment, which was successfully removed through an infratentorial supracerebellar approach, is presented. The preoperative diagnosis was made by means of computed tomography together with histographic analysis. We review similar cases reported in the literature and discuss the clinical feature, diagnostic aspects, and surgical management.
Insights
A rare pineal region meningioma, lacking dural attachment, was successfully removed using an infratentorial supracerebellar approach. This case highlights diagnostic and surgical considerations for atypical brain tumors.
Area of Science:
- Neurosurgery
- Neuropathology
- Neuroradiology
Background:
- Pineal region tumors are rare and challenging to manage.
- Meningiomas typically arise from the dura mater, making a non-dural attachment unusual.
- Accurate preoperative diagnosis is crucial for surgical planning.
Observation:
- A rare meningioma was identified in the pineal region without dural attachment.
- Computed tomography (CT) and histographic analysis were used for preoperative diagnosis.
- The tumor was surgically removed via an infratentorial supracerebellar approach.
Findings:
- Successful resection of a non-dural-based pineal region meningioma.
- Demonstration of the infratentorial supracerebellar approach as a viable surgical option.
- Correlation of imaging findings with histopathological analysis.
Implications:
- This case expands the understanding of meningioma presentation and surgical possibilities.
- Highlights the importance of advanced imaging in diagnosing rare intracranial lesions.
- Provides insights into the surgical management of challenging pineal region tumors.
