From: Perinatal post-mortem ultrasound (PMUS): radiological-pathological correlation
Post-mortem cranial ultrasound images (top row), with matched unenhanced post-mortem CT images (bottom row) of a fourteen day old term neonate who died from a metastatic fibrosarcoma affecting the right thigh. Both imaging modalities were performed 3 days after death. The coronal (a, c) and sagittal (b, d) images demonstrate bilateral lateral ventricular dilatation with several hyperechoic and hyperdense metastatic deposits within the cerebellum (white arrows) and along the falx (dashed arrow). There is loss of grey white matter differentiation with poorly defined ventricles on the CT compared to ultrasound, given the significant underlying cerebral oedema
