Abstract

|
Lymphoplasmacyte-rich meningioma is a rare WHO Grade I subtype of meningioma. The lymphoplasmacyte-rich meningioma does not have typical imaging features of a meningioma so it can mimic intracranial inflammatory condition or brain neoplasm. We report the clinicopathologic features of lymphoplasmacyte-rich meningioma in a 35-year-old woman. She suffered from progressive headache, dizziness and tinnitus over two years. The tumor exhibited atypical neuroimaging features, including obvious peritumoral edema and irregular enhancing components. She underwent total resection and histologic examination revealed a meningioma with numerous plasma cells. Her symptoms have since resolved and there has been no evidence of tumor recurrence after one year of follow-up.
