Lymphoplasmacyte-rich meningioma (LPRM), the most rare variant of meningiomas, features extensive lymphoplasmacytic infiltrates. Although the jugular foramen (JF) is occasionally involved by several types of tumor, such as paragangliomas and schwannomas, meningioma in the JF is an infrequent disease. Here we present an extremely rare case of LPRM found in the JF. A 55-year-old woman complained of paresis in her right eyelid and palsy in the right side of her lip. Hoarseness and dysphagia also occurred in the following month. Radiologic examinations disclosed a mass lesion in the right JF, and the tumor was operatively removed. Microscopically, the tumor was composed of extensive lymphoplasmacytic infiltration with mild vascular proliferation and scattered sheets of epithelioid cells with plump cytoplasm. Although the obvious whorl formation or psammoma bodies were not observed, by immunochemistry the epithelioid cells were positive for epithelial membrane antigen and also progesterone receptor, indicating a meningothelial cell origin. Considering the histological and radiologic findings, we finally diagnosed the case as LPRM, making this the second reported case of LPRM in the JF.
