Insights
This case report details a rare co-occurrence of Burkitt-type lymphoma and meningioma in a patient with a cerebral aneurysm. The findings highlight the diagnostic and therapeutic challenges of multiple brain pathologies.
Area of Science:
- Neurology
- Oncology
- Neurosurgery
Background:
- Meningiomas and lymphomas are distinct primary brain tumors.
- Cerebral aneurysms present a significant vascular risk.
- Coexistence of these pathologies is exceptionally rare.
Observation:
- A 49-year-old male presented with headache and right hemiparesis.
- Neuroradiology identified a left frontal mass and an unruptured middle cerebral artery aneurysm.
- Initial surgery debulked a meningioma; a second surgery revealed Burkitt-type lymphoma.
Findings:
- Histopathology confirmed a benign meningioma and a subsequent Burkitt-type lymphoma.
- The lymphoma's origin may relate to the meningioma's irritative effect.
- The cerebral aneurysm was deemed an independent, coincidental finding.
Implications:
- This case underscores the importance of comprehensive diagnostic evaluation in complex neurological presentations.
- Management requires a multidisciplinary approach for coexisting neoplastic and vascular lesions.
- Further research may explore potential links between different tumor types and vascular anomalies.
Abstract:
A rare case of coexistent Burkitt-type lymphoma and meningioma associated with an unruptured cerebral aneurysm is presented. A 49-year-old male complaining of headache and right hemiparesis was admitted to our hospital. Neuroradiological examination revealed a multinodular mass in the left frontal convexity and an unruptured cerebral aneurysm at the M1 portion of the left middle cerebral artery. He underwent an operation for tumor removal and aneurysm clipping. Histological examination revealed the tumor to be a typical meningotheliomatous meningioma without malignancy. However, a second operation was necessary for another tumor invading into the left frontal lobe, which proved to be a Burkitt-type lymphoma. The second tumor may have been resulted from irritative effect of the first tumor, but the aneurysm was considered purely coincidental.
