Symptoms of leptomeningeal metastasis from lung cancer

Symptoms of leptomeningeal metastasis from lung cancer may include headache, vision loss, syncope, and others. Specific symptoms vary among individuals and are associated with multiple factors such as the affected areas of the brain and pathological stage. A detailed analysis is as follows:

1. Headache

After lung cancer cells metastasize to the brain, they not only damage brain tissue but also cause persistent leakage of blood vessels and cerebrospinal fluid. This leads to sustained intracranial hypertension, resulting in chronic or persistent headaches and dizziness.

2. Vision Loss

When cancer infiltrates and damages functional central nerves controlling vision, hearing, smell, and other senses, it can impair or reduce sensory functions such as vision, hearing, and olfaction. This results in a series of secondary symptoms including decreased vision, hearing loss, and reduced sense of smell.

3. Syncope

This symptom typically occurs in the late stages of cancer and is caused by a combination of factors such as intracranial hypertension syndrome and damage to cranial nerves. Patients may experience sudden episodes of fainting or even fall into a deep coma.

In addition to the above symptoms, patients may also develop other signs such as difficulty breathing. If any of these adverse symptoms occur, prompt medical evaluation is essential to alleviate symptom severity and prolong patient survival.
