Screening
Parents of a child with TSC should be evaluated for the disease. Asymptomatic siblings should be evaluated if the parents are not available or if the possibility exists of one of the parents having TSC.[1]
Prenatal ultrasound at 18 to 20 weeks can identify major structural anomalies in about 60% of patients evaluated, including fetal cardiac rhabdomyomas, polycystic kidney disease, or central nervous system lesions.[46] When a fetal structural anomaly is identified, referral to an appropriate tertiary ultrasound unit is suggested. Further evaluation of the fetus and parents may be indicated to aid in the identification of underlying TSC.[47]
