In the same foetus at 21 weeks gestation, described in Fig. 6, there were several intracranial abnormalities. Post-mortem ultrasound images of the brain in axial plane (a) and the cervical spine in sagittal plane (b) are matched with corresponding T2-weighted post-mortem MRI images (c, d). Both imaging modalities were acquired 7 days after delivery. This infiltrating intracranial mass affecting the brainstem and both temporal lobes was also a teratoma. The lesion is mostly echogenic on ultrasound but of heterogenous signal intensity on MRI
