Dystrophic calcification of the fetal myocardium

Intramural cardiac masses were detected antenatally in three fetuses by ech ocardiography. The masses were initially thought to be rhabdomyomas. All th ree pregnancies were terminated and histology showed dystrophic calcificati on in all, with no evidence of tumour. Therefore, dystrophic calcification of the fetal myocardium may have a similar appearance to single or multiple rhabdomyomas. This should be considered when counselling parents after det ection of masses in the fetal heart, particularly when considering the risk of associated tuberous sclerosis.
