Arachnoid Cysts

Arachnoid cysts (ACs) are pouches of cerebrospinal fluid surrounded by a membrane of arachnoid cells and collagen. ACs are typically found on the surface of the brain or spinal cord, and constitute about 1% of intracranial masses. Though most cases begin during infancy, many patients are not diagnosed until much later in life.

Despite being relatively common, the severity of AC symptoms remains poorly understood. Some ACs remain asymptomatic for a patient’s entire life. Others may present with serious neurological symptoms such as seizures, developmental delays, and altered mental status. Though they can be caused by injury or infection, most ACs are present from birth. Despite this, the genetic cause of congenital ACs is relatively unknown. Our team is leading the field of AC research as we work to discover the genetic mechanisms underlying this disease.

We are continuously recruiting patients with diagnoses of congenital arachnoid cysts in support of this effort. Affected individuals and their families are welcomed and encouraged to participate!
