Introduction
If a patient's cyst is small and grows slowly without noticeable enlargement over a long period, regular follow-up examinations at the hospital are sufficient, and it may never require treatment. However, if the arachnoid cyst is large or growing rapidly, and no active treatment is pursued, symptoms such as dizziness, headache, vomiting, and impaired consciousness may develop, necessitating medical treatment at a hospital.
If a patient's arachnoid cyst is small and grows slowly, it usually requires no intervention throughout life—regular follow-up examinations are sufficient. However, if the cyst is large or growing rapidly, medical attention is necessary.
Arachnoid cysts result from abnormal splitting of the arachnoid membrane during development. The cyst wall is typically composed of arachnoid tissue, glial tissue, and pia mater, and the cyst contains cerebrospinal fluid-like liquid. These cysts are commonly located on the brain surface, within cerebral fissures, or in cisterns. Most are solitary, though a few cases may be multiple. Generally, arachnoid cysts are congenital benign brain lesions. If the cyst is small and shows slow or no growth over time, regular hospital check-ups are adequate, and often no treatment is needed for the entire lifetime. However, if the arachnoid cyst is large or growing quickly, and left untreated, patients may develop symptoms such as dizziness, headache, vomiting, and impaired consciousness. In such cases, surgical removal of the lesion at a hospital is required.
Patients should develop healthy lifestyle habits, maintain a light diet, and consume moderate amounts of fresh fruits and vegetables, such as apples and tomatoes. They should go to bed early, rise early, ensure sufficient sleep, and avoid staying up late.
