Mesenchymal Hamartoma : Prenatal and Postnatal Diagnosis by Imaging

Abstract EN

We present a case of a twin pregnancy in which one fetus developed a rapidly growing unilateral intrathoracic tumor.

While a cystic adenomatoid malformation was suspected in the ultrasound scan, the magnetic resonance scan suggested a pulmonary blastoma or a bronchioalveolar carcinoma.

Postnatal chest radiography and contrast-enhanced computed tomography of the affected newborn were performed, and it was ruled out the possibility of malignant origin.

Finally, the anatomopathologic exam revealed the presence of a mesenchymal hamartoma in the chest wall.

Nevertheless, parents refused any treatment for the newborn.
