Scabies is a cutaneous infestation caused by Sarcoptes scabiei var. hominis, a small mite that performs its whole life cycle within the epidermis. In this case report, we provide images of the sonographic signs of scabies. We found that the adult mite can be seen as a hyperechoic well-defined ovoid area within the epidermal layer at the end of the hypoechoic burrow, while the eggs correspond to tiny heteroechoic dots along the burrow. In conclusion, ultrasound may prove useful to differentiate between inhabited vs non-inhabited scabiotic burrows.
疥疮是由人疥螨引起的皮肤寄生虫病,这种小螨在表皮内完成其整个生命周期。在本病例报告中,我们提供了疥疮的超声征象图像。我们发现,在低回声隧道末端的表皮层内,可以看到成虫呈高回声、界限清楚的卵圆形区域,而卵则对应于沿隧道的微小异回声小点。总之,超声检查可能有助于区分有螨虫和无螨虫的疥疮隧道。
