Tumours of the fetal body are rare, but lesions have been reported in all spaces, especially in the mediastinum, the pericardial space, the adrenals, the kidney, and the liver. Lymphangioma and teratoma are the commonest histological types encountered, followed by cardiac rhabdomyoma. Adrenal neuroblastoma is the commonest malignant tumour. Imaging plays an essential role in the detection and work-up of these tumours. In addition to assisting clinicians it also helps in counselling parents. Most tumours are detected by antenatal US, but fetal MRI is increasingly used as it brings significant additional information in terms of tumour extent, composition and complications.
