To report a rare case of primary CNS MALT lymphoma in the right lateral ventricle, emphasizing its rarity, and review existing literature on similar cases.
Key Findings:
The case expands the anatomical spectrum of CNS MALT lymphoma.
Only eight cases of ventricular MALT lymphoma have been reported, often misdiagnosed as other conditions.
Postoperative treatment included ifosfamide and a BTK inhibitor, with no recurrence observed at follow-up, indicating a favorable prognosis.
Interpretation:
The findings suggest that MALT lymphoma should be considered in the differential diagnosis of intraventricular lesions, particularly when imaging suggests meningioma or metastasis, to avoid misdiagnosis.
Limitations:
Limited number of reported cases makes it difficult to draw broad conclusions.
Potential infectious or inflammatory triggers for ventricular MALT lymphoma remain unclear, and biases in literature review may affect findings.
Conclusion:
This case underscores the importance of considering MALT lymphoma in the differential diagnosis of intraventricular masses and contributes to the understanding of its clinical presentation and management, highlighting the need for clinician awareness.
