On follow-up assessment of the patient at month 3, echocardiography showed significant regression of rhabdomyomas, and ECG and 24-hour Holter examination revealed sinus rhythm without WPW syndrome (Fig.
Cardiac rhabdomyoma is characterized by large glycogen containing vacuolated cells and is also referred to as rhabdomyomatosis, congenital glycogen tumor, circumscribed glycogen storage disease, nodular glycogen degeneration, nodular glycogen, and nodular glycogen infiltration (KIZAWA et al., 2002).
In terms of prevalence, hypomelanotic macules and tubers or other cortical dysplasias were the most prevalent TSC features, both of which occurred at a rate of 94%; the next most common features were subependymal nodules (SENs), which were seen in 90% of cases, and cardiac rhabdomyomas, seen in 82%.
In more than 75% of cases, intracardiac tumours are benign and are represented especially by myxoma (50%) and rhabdomyoma (20%).
