Introduction
Patients with meningeal metastases and elevated intracranial pressure should prioritize rest and avoid strenuous physical activity. Diet should be light and low in salt. Under a physician’s guidance, patients may receive medications to reduce intracranial pressure—such as osmotic diuretics—or other diuretic agents. In cases of severe symptoms, surgical interventions may be considered, including emergency lateral ventricular puncture or external ventricular drainage.
Increased intracranial pressure (ICP) due to leptomeningeal metastasis can be managed through general supportive measures, pharmacological therapy, or surgical intervention.
1. General Supportive Measures
Patients with leptomeningeal metastasis and elevated ICP should prioritize rest and avoid strenuous physical activity. For bedridden patients, elevating the head of the bed by approximately 30° is recommended. A light, low-sodium diet is advised, and patients should ensure adequate sleep to maintain mental relaxation.
2. Pharmacological Therapy
Under physician guidance, patients may receive osmotic diuretics to reduce ICP. Commonly used agents include glycerol fructose and mannitol. Alternatively, loop or thiazide diuretics—such as torasemide or hydrochlorothiazide—may be administered to rapidly lower ICP and alleviate associated pain.
3. Surgical Intervention
In cases of severe symptoms unresponsive to medical therapy, surgical management may be necessary. Procedures such as emergency lateral ventricular puncture or external ventricular drainage (EVD) can be performed. Delay in surgical intervention may pose a life-threatening risk to the patient.
