Arachnoid Cysts
Arachnoid Cysts are fluid-filled sacs that develop within the arachnoid membrane, a thin layer surrounding the brain and spinal cord. Although most Arachnoid Cysts are congenital and present at birth, they can also occur later in life due to trauma or injury.
Symptoms of Arachnoid Cyst
The symptoms of Arachnoid Cysts can vary depending on their size, location, and the pressure they exert on nearby brain structures. Common symptoms may include:
Headaches: Recurring headaches that may worsen over time.
Seizures: Unexplained seizures or episodes of altered consciousness.
Nausea and vomiting: Persistent nausea and vomiting, especially in the morning.
Developmental delays: Delays in reaching developmental milestones, particularly in infants and young children.
Vision problems: Blurred vision, double vision, or other visual disturbances.
Balance and coordination difficulties: Problems with balance, coordination, or gait.
Causes of Arachnoid Cysts
The exact cause of Arachnoid Cysts is not fully understood. However, researchers believe that they may develop due to a combination of genetic factors and disruptions in the development of the central nervous system during fetal development. Trauma or injury to the head or spine can also contribute to the formation of Arachnoid Cysts later in life.
Treatment Options for Arachnoid Cysts
The treatment of Arachnoid Cysts depends on several factors, including the size, location, and symptoms they cause. Treatment options may include:
Observation: Small, asymptomatic cysts may be monitored closely without immediate intervention.
Medications: Medications may be prescribed to manage symptoms such as headaches or seizures.
Surgical intervention: Surgical treatment may be necessary if the cyst is causing significant symptoms or if it poses a risk of complications. The surgical options include cyst drainage, cyst removal, or placement of a shunt to divert the fluid.
