Abstract

CNS mesenchymal, non-meningothelial tumors arise from craniospinal meninges, supporting tissues, vasculature, or surrounding osseous structures, representing the homologous of neoplasms encountered far more frequently in the somatic soft tissues or bones. These neoplasms can occur in patients of any age and may arise anywhere along the neuroaxis and its coverings, with tumors arising in meninges more common than ones originating within CNS parenchyma or in choroid plexus. This chapter primarily emphasizes the cytomorphologic features and differential diagnosis of the most common CNS mesenchymal tumors (hemangioblastoma and solitary fibrous tumor/hemangiopericytoma) but also includes the cytomorphology of lipoma, rhabdomyosarcoma, Ewing sarcoma, fibrosarcoma, chordoma, and osteosarcoma involving the CNS.
