C79.3

Clinical Causes: Spread of primary cancers from organs such as the lungs, breasts, skin (melanoma), kidneys, or gastrointestinal tract to the brain and meninges. Cancer cells traveling through blood vessels or lymphatic channels from the original site to the brain. Advanced stages of systemic cancers that have disseminated beyond their primary location.

Key Symptoms: Headaches that may worsen over time or occur suddenly. Seizures or convulsions. Cognitive changes such as memory loss, confusion, or difficulty concentrating. Weakness or numbness in limbs or facial muscles. Visual disturbances like blurred vision or loss of vision. Nausea and vomiting, especially in the context of increased intracranial pressure. Balance problems or difficulty walking.

Diagnosis Path: Diagnosis typically involves a comprehensive approach including medical history, physical and neurological examinations, and imaging studies such as MRI or CT scans of the brain. Biopsy procedures may be performed to confirm the diagnosis and determine the characteristics of the metastatic tumor. Additional tests might include cerebrospinal fluid analysis and advanced imaging to identify the primary site of cancer.

Treatment Protocols: Management of secondary malignant brain and meninges tumors is tailored to the individual's overall health, location and size of metastases, and the primary cancer type. Common treatment options include: - Surgery: To remove accessible tumors and relieve pressure. - Radiation therapy: Focused or whole-brain radiation to target metastatic sites. - Chemotherapy: Systemic treatments to control tumor growth, depending on the primary cancer's sensitivity. - Targeted therapies and immunotherapy: Emerging options for specific cancer types with molecular targets. - Supportive care: Managing symptoms such as pain, swelling, seizures, and neurological deficits. Multidisciplinary teams aim to optimize quality of life, symptom control, and, when possible, prolong survival.
