a–c Klippel-Trenaunay syndrome in a foetus at 22 weeks gestation, following termination of pregnancy. The external photograph of the lower limbs at autopsy (a), seen from behind, reveals an enlarged right leg with discoloured red and purple overlying skin. The post-mortem lateral radiograph of this right limb (b) reveals numerous small hyperdense foci within the soft tissues which are tiny phleboliths. At post-mortem ultrasound of the right thigh (c), obtained in axial plane 1 day after delivery, the small phleboliths were well seen with posterior acoustic shadowing. One of these is demonstrated with a solid arrow, the dotted arrow represents the right femur. At autopsy, extensive ectatic thin-walled vessels containing thrombus were seen in the right leg and in keeping with a vascular malformation. Due to lack of circulation and small diameter of vessels, this vascular anomaly could not be well depicted on ultrasound
