Overview

Subependymal giant cell astrocytoma is the most common central nervous system tumor in patients with tuberous sclerosis complex. Approximately 10-20% of patients with tuberous sclerosis develop subependymal giant cell astrocytoma. It is a disease that tends to commonly affect the pediatric population with males being more affected than females.

Epidemiology and Demographics

Incidence

  • The incidence of subependymal giant cell astrocytoma is approximately 0.027 per 100,000 person-years.[1]

Prevalence

Age

  • Subependymal giant cell astrocytoma is a disease that tends to affect the pediatric, adolescent, and young adult population.[4]
  • The mean age at diagnosis is 13 years.[5]
  • It commonly presents in the first two decades of life.[6]
  • It becomes symptomatic, clinically and pathologically, between 8 to 19 years of age.[2]

Race

  • There is no racial predilection to subependymal giant cell astrocytoma.

Gender

  • Males are more commonly affected with subependymal giant cell astrocytoma than females.[2][4][7]
