Fetal Gastric Pseudomass: Case Report

摘要

Second trimester fetal ultrasonography and, less frequently third trimester fetal scan, can reveal an intragastric well-defined, not vascularized, echogenic image, that spontaneously disappears in most cases. This image, called Fetal Gastric Pseudomass, seems to be the result of a still inadequate gastric peristalsis and / or an aggregation of epidermal, urothelial, amniotic cells, blood and fluff swallowed by the fetus. A careful fetal abdominal ultrasonography, can show the difference between the Fetal Gastric Pseudomass and pathological neoformations of the stomach and adjacent organs. Moreover, the exam can recognize any pathological pictures of the placenta too, eventually related to the FGP formation. This report shows an echographic image referred to a Fetal Gastric Pseudomass, suspected to be due to a previous endo-amniotic bleeding occurred between the 31st week and the 34th week, not clinically detected during pregnancy.
