Abstract
BACKGROUND
Primary non-dural central nervous system mucosa-associated lymphoid tissue (MALT) lymphoma is a rare indolent B-cell lymphoma, with only a few reported cases worldwide.
CASE SUMMARY
A 33-year-old man presented with a 5-mo history of left blepharoptosis and a 4-mo history of right limb numbness and weakness. Magnetic resonance imaging showed a significantly enhanced mass in the left midbrain. Subsequent positron emission tomography revealed that the lesion had increased glucose uptake. A stereotactic robotic biopsy supported a diagnosis of MALT lymphoma. Then he was treated with radiation therapy (30Gy/15F), which resulted in complete remission. We also review the literature on brain parenchymal-based MALT lymphoma, including the clinical presentation, treatment options, and outcomes.
CONCLUSION
Although there is no consensus on the optimal treatment for this rare disease, patients can respond well when treated with radiotherapy alone.
Core Tip: Primary central nervous system mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease, especially in the brain parenchyma. A clear diagnosis is important because it can be cured. This report presents the treatment of MALT lymphoma developing in the midbrain. The patient received local radiotherapy and was in complete remission without apparent adverse effects.
