Abstract:
Objective To investigate the MRI features of intracranial lymphoplasmacyte-rich meningioma and the corelation between the MRI features and pathologic findings. Methods The MRI and pathologic data of 7 patients with lymphoplasmacyte-rich meningioma were reviewed retrospectively. All cases were proved by surgery and pathological examinations. Results All lesions were solitary. The tumors crawled along meninges in 6 cases and in 5 cases the tumors did not appear as mass lesions. In 2 cases, the tumors appeared as half-moon. The boundary of all of the tumors was unclear, accompanying heavy peritumoral brain edema. The brain invasion can be seen in 7 cases. The lesions showed hypo-isointense signal on T1 WI in 7 cases, hyper-isointense signal in 5 cases and hypo-isointense in 2 cases on T2 WI.Enhancement scan demonstrated marked enhancement in 7 cases. Extensive thickening of the meninges was observed in 6 cases. Pathological results showed that the cells were abundant and diversified, with a great quantity of lymphoplasmacytes, and there were typical meningeal epithelial cells area in the surgical specimen. Conclusion The MRI findings of lymphoplasmacyte-rich meningioma show some features different from other common meningiomas, which would be helpful to the diagnosis and differential diagnosis.
