Infection during pregnancy is usually mild (2). The risk is highest in the third trimester with increased hospital admission rates and maternal and fetal compromise (3). Post-COVID placentitis is uncommon but the effect on the placenta and the fetus is extensive (4). We present a case correlating clinical, imaging, and pathological findings. Case Report: A 29-year-old para 2 gravida 1, with a normal fetal anomaly scan at 22 weeks gestational age (GA) contracted COVID at 24 weeks gestation. Fully recovered but reported reduced fetal movements at 27 weeks and 1\u2009day. Imaging: US scan showed bright echoes within the brain, small lungs, and oligohydramnios. MRI showed abnormal brain signals, small lungs, and oligohydramnios but also a very abnormal placenta. Reduced and heterogeneous T2 signal and a marked reduction in the DWI signal intensity. The placental size was markedly reduced (volume 785.6\u2009cm3 expected for GA is 5604.8\u20135952.4\u2009cm<jats:sup>3<\/jats:sup>. The surface area of attachment was 3220\u2009mm<jats:sup>2<\/jats:sup>, expected 22180.4\u201329293.2\u2009mm<jats:sup>2<\/jats:sup>). Pathology: The placenta was small (fifth centile) with massive perivillous fibrin deposition and multifocal chronic deciduitis. Histology revealed placental chorionic villi showing diffuse sclerotic changes surrounded by perivillous fibrin deposition in the intervillous space. The basal plate revealed multifocal chronic deciduitis. When imaging the fetus, it is important to examine the placenta and correlate any abnormalities. The placenta is a forgotten organ and should be routinely included and assessed to allow the detection of important abnormalities. <\/jats:p>","DOI":"10.1259\/bjrcr.20220132","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T13:49:03Z","timestamp":1673531343000},"source":"Crossref","is-referenced-by-count":0,"title":["MRI features of perifibrinous deposits in the placenta due to COVID-19"],"prefix":"10.1093","volume":"9","author":[{"given":"Hiba","family":"Alessa","sequence":"first","affiliation":[{"name":"Reproductive and Developmental Medicine, University of Sheffield, Sheffield, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Cesar","family":"Peres","sequence":"additional","affiliation":[{"name":"Sheffield Children\u2019s Hospital, Sheffield, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emma","family":"Ferriman","sequence":"additional","affiliation":[{"name":"Sheffield Teaching Hospitals NHS Foundation Trust, Sheffield, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Fry","sequence":"additional","affiliation":[{"name":"Sheffield Teaching Hospitals NHS Foundation Trust, Sheffield, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elspeth","family":"Whitby","sequence":"additional","affiliation":[{"name":"Reproductive and Developmental Medicine, University of Sheffield, Sheffield, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","reference":[{"key":"b1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.7233"},{"key":"b2","doi-asserted-by":"crossref","DOI":"10.1136\/bmj.m2107","volume":"369","author":"Knight M","year":"2020","journal-title":"BMJ"},{"key":"b3","doi-asserted-by":"publisher","DOI":"10.1186\/s12916-020-01798-1"},{"key":"b4","doi-asserted-by":"publisher","DOI":"10.1016\/j.placenta.2021.01.012"},{"key":"b5","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2022-0029-SA"},{"key":"b6","doi-asserted-by":"publisher","DOI":"10.3389\/fmed.2021.677001"},{"key":"b7","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2012.10.002"},{"key":"b8","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2021-0586-SA"},{"key":"b9","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.mm7047e1"},{"key":"b10","doi-asserted-by":"publisher","DOI":"10.18632\/aging.104015"}],"container-title":["BJR|case reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.birpublications.org\/doi\/pdf\/10.1259\/bjrcr.20220132","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T15:51:55Z","timestamp":1705074715000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/bjrcr\/article\/7279144"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2023,1]]}},"alternative-id":["10.1259\/bjrcr.20220132"],"URL":"https:\/\/doi.org\/10.1259\/bjrcr.20220132","relation":{},"ISSN":["2055-7159"],"issn-type":[{"type":"electronic","value":"2055-7159"}],"subject":[],"published":{"date-parts":[[2023,1]]},"article-number":"20220132"}}
