    Primary CNS MALT lymphoma is a rare, low-grade B-cell lymphoma, with this case occurring in the right lateral ventricle of a 62-year-old man.

  • 2

    The patient underwent gross total resection followed by ifosfamide and a BTK inhibitor, with no evidence of recurrence at the latest follow-up.

  • 3

    Only eight previous cases of ventricular MALT lymphoma have been reported, often misdiagnosed as meningioma or metastasis.

  • 4

    Chronic inflammation may be linked to MALT lymphomas, but infectious triggers in ventricular cases remain unclear.

  • 5

    This case suggests that lateral ventricular tumors may originate from pia mater folds of the choroid plexus, warranting consideration in differential diagnoses.
