These findings with features of tuberous sclerosis suggest the diagnosis, which can be confirmed by echocardiography or angiocardiography. Surgical treatment of multiple nodules is usually ineffective, and the prognosis is poor beyond the first year of life. Teratomas of the pericardium, often attached to the base of the great vessels, are rarer than cysts or lipomas. These tumors usually occur in infants. Generally asymptomatic, they are often discovered on routine chest x-ray.
Surgery is necessary only to rule out more serious tumors.
