Anaplastic astrocytoma and glioblastoma account for approximately 38% of primary brain<unk> ; meningiomas and other mesenchymal<unk>  account for approximately 27%. Other less common primary brain<unk>  include pituitary<unk> , schwannomas, CNS lymphomas, oligodendrogliomas, ependymomas, low-grade astrocytomas, and medulloblastomas, in decreasing order of frequency. Schwannomas, meningiomas, and ependymomas account for as much as 79% of primary spinal<unk> . Other less common primary spinal<unk>  include sarcomas, astrocytomas, vascular<unk> , and chordomas, in decreasing order of frequency. The familial<unk> syndromes (and respective chromosomal abnormalities that are associated with CNS neoplasms) include neurofibromatosis type I (17q11), neurofibromatosis type II (22q12), von Hippel-Lindau disease (3p25-26), tuberous sclerosis (9q34, 16p13), Li-Fraumeni syndrome (17p13), Turcot syndrome type 1 (3p21, 7p22), Turcot syndrome type 2 (5q21), and nevoid basal cell carcinoma syndrome (9q22.3).
