Mucosa‑associated lymphoid tissue in the central nervous system presenting as meningioma: A case report.

Mucosa-associated lymphoid tissue (MALT) lymphoma involving meningeal tissue is rare condition, easily mistaken for meningiomas upon imaging. In this report, a case of primary left temporal lobe MALT lymphoma that was initially misdiagnosed as temporal meningioma is presented, with subsequent investigation into the mechanism and treatments. Clinically, MALT lymphomas can be easily confused with meningiomas based solely on imaging and clinical manifestations. MALT lymphomas are indolent, localized lesions that can be cured through surgical resection and radiotherapy. Currently, radiotherapy is the most commonly used treatment; however, the patient in the present report did not receive any chemotherapy or radiotherapy after surgery, and recent related examinations revealed a recurrence of lymphomas that had metastasized throughout the body. As a result, future patients may benefit from chemotherapy or radiotherapy, and clinicians should be more meticulous regarding patient follow-up.
