A case of a heavily calcified, mature placenta simulating the appearance of a fetus papyraceus is presented. Calcification surrounding the more sonolucent cotyledons simulated the body and limbs of a dead fetus. Awareness of the morphologic alterations which occur as the placenta matures should prevent confusion of normal placental changes with a pathologic entity.
本文报告一例高度钙化的成熟胎盘，其外观类似纸样胎儿。围绕着透声性较好的小叶的钙化模拟了死胎的身体和四肢。了解胎盘成熟时发生的形态学改变，应可避免将正常胎盘变化与病理实体相混淆。
