C69-C72: Malignant neoplasms of eye, brain and other parts of central nervous system

C70: Malignant neoplasm of meninges

A malignant neoplasm of the meninges represents a group of conditions characterized by the uncontrolled growth of harmful or cancerous cells within the meninges, the protective membranes that surround the brain and spinal cord. These conditions may be caused by different factors, including exposure to certain chemicals or radiation, inherited genetic disorders, and history of other brain or spinal cord cancers. Symptoms commonly include persistent headaches, nausea, vomiting, and changes in behavior or personality. Progressive growth of the tumor can lead to more serious complications such as neurological deficits, seizures, and eventually escalation to a life-threatening condition. These diseases predominantly affect the nervous system, leading to a range of neurological problems.
