Imaging Findings and Clinical Features of Intracal Lymphoplasmacyte-Rich Meningioma

Abstract

Lymphoplasmacyte-rich meningioma is a seldom-seen subtype meningioma of WHO grade I, often accompanying anemia or polyclonal immunoglobulin hyperplasia, which can recover to normal state after removing the masses. The masses showed higher density and without clear boundary in plain CT scan, and most of the tumors appear with irregular shape, obvious edema, and significant enhancement in the MRI scan. The prognosis is favorable after surgical resection and the recurrence rate is low.
