Meningiomas are tumors that most likely originate from arachnoid cap cells and account for 13–26%  of all intracranial tumors.[13] According to the World Health Organization, they are subclassified as benign (grade I), atypical (grade II), or anaplastic (grade III).[10] The vast majority of meningiomas are benign, with only 1.0–2.8%  being malignant.[13] However, the malignant meningiomas represent a particularly aggressive tumor entity and have a reported 5-year survival rate of 32–64% .[18] An even smaller percentage of malignant meningiomas metastasize, about 0.1%  of all meningiomas.[7] The most common site are the lungs, but liver, bone, skin, subcutaneous tissue as well as locations along the craniospinal axis have also been repeatedly reported as sites of metastases.[3] Metastases to the parotid gland are very rare. In the reviewed literature on PubMed with the search terms “parotid gland” and “meningioma”, only 4 cases are described.[1] [5] [20] [22]
