Lymphoplasmacyte-rich meningioma
Updates to Case Attributes
Lymphoplasmacyte-rich meningiomas are rare histological variants of benign (WHO grade I) meningiomas, characterised by prominent lymphoplasmacytic infiltrates into the tumour, sometimes rendering the underlying meningothelial component inconspicuous.
Clinical features include a predilection for relatively young patients, often with secondary hypergammaglobulinemia and anemia.
Typically, the tumor is hyperdense on non-contrast CT and iso- to hypointense on T1-weighted images. T2-weighted images show mixed hyper- to iso-intensity more often than iso- to hypointensity. Diffusion restriction can be seen.Post-contrast MR images show strong and homogeneous enhancement.Cyst formation can be detected in 30 % and peritumoral brain edema in nearly 100 % of the cases.
