“…However, the majority of cases involving CB disappear in the second trimester, which is consistent with the findings of earlier researches [1,2,3,4] , and raises the notion that the body can reabsorb the underlying hematoma. Fang, Yunjing, et al's findings differ from those of Hisham M. et al, who reported CB in the third trimester that continues to report a CB until delivery [11,12] .…”

Objective:The purpose of this study is to provide some insight on our practical contact of the chorionic bump in upper Egypt, including its prevalence, subsequent prenatal course, and pregnancy outcome. Patients and Methods: All referred pregnant ladies to our specialized feto-maternal clinic at at Sohag, Aswan and Asuit governorate were offered ultrasound in early pregnancy to confirm pregnancy, diagnosis of PUL, determination of viability, suspected partial mole, and vaginal bleeding. The preceding LMP or conception date were used to estimate gestational age. all patients were asked for infertility treatment, previous obstetric history, coagulopathy or aspirin intake. Transvaginal ultrasound was done using Philips ClearVue 650. The appearance or lack of a chorionic bump was verified by two expert examiners differently. and documented for number of the CB, its position, appearance of yolk sac, fetal heart rate, then the size of the chorionic bump was measured in three dimensions and volume of the bump was calculated by this formula (length × width × height/2), 3D TVS was offered to all the patients follow up was done over next 2 weeks. the sonographic difference was compared. Results: Throughout span of a 4-year studies from June 2019 to December 2022, The incidence of chorionic bump in our study was 0.45%, with 12 patients diagnosed after examination of 2610 patients aged 19 -41 years old. Presentation of the cases were variable, with PUL (8.3%), determining viability (16.7%), and checking for suspected partial moles (25%) faced in most the cases. The identification of a chorionic bump made when a ultrasound revealed an irregular, convex protrusion from the choriodecidual surface into the first-trimester gestational sac (GS). The lesion's dimensions ranged from 0.05 to 10.8 cm3, and also its average diameter was around 0.6 and 3.4 cm. Twelve individuals were detected with chorionic bumps; nine (75%) had a single bump, three (25%) had two bumps, and in this latter group all pregnancies ended in demise (100%) as a consequence. 3 of the twelve patients with chorionic bump were wrongly diagnosed as partial moles. The size of CB and pregnancy outcome were not strongly linked. Overall, (8/12) (66.6%) showed live birth; one was Preterm delivery admitted to NICU then discharged. (33.3%) experienced fetal demise; three of them were aborted at the time of CB diagnosis. Interestingly, the time period required for the disappearance of CB varied, but most cases experienced disappearance during the next visit; over 2weeks suggesting absorption of the pathology i.e. hematoma. Finally, in none of the cases there were any possible long-term defects. Conclusion: Our research has revealed that the chorionic pump is uncommon finding that may have misdiagnosed during first trimester screening, almost always, it is slowly fading away over time. representing its pathology as a hematoma, and it doesn't considerably increase the likelihood of miscarriage in the first trimester unless it is multiple. Despite this, obstetricians and radi...

“…Fo r these reasons, def initive surgical treatment with dilation and curettage was decided, sending the tissue collected f rom the curettage procedure f or complementary histopathological study. It was expected that the results would show sections or cystic-based areas in the histopathological study with the possibility of f inding f ibrin tissue and/or scattered chorionic villi covered by cytotrophoblasts and syncytiotrophoblasts, as has been seen in other publications (10) . However, in our histopathological analysis report, it showed: abundant ovulodecidual remains, various f ragments of irregular tissue which together measure 7x4.5x2cm, with areas of a light brown membranous appearance, alternating areas of a hairy, light and dark brown appearance, the tissue presents data of non-specific moderate acute deciduitis with f ocal microabscess in addition to f irst trimester chorionic villi and Arias-Stella reaction.…”

“…However, adequate surveillance should be carried out in this type of case, since some authors have postulated that large subamniotic hematomas may be associated with fetal growth restriction and/or early embryonic death (6) . An additional associated risk is related to its location; if they are close to the umbilical cord insertion site, and especially if they are large, they can compress the placental vessels and the umbilical cord, leading to adverse f etal outcome (10) .…”

Background: Chorionic bump involves the gestational sac and can be visualized in first trimester ultrasound. It is described as an irregular convexity that protrudes towards the gestational sac and corresponds to the formation of a hematoma on choriodecidual surface. Objective: This is a clinical case reported in a second level hospital. An updated search was carried out on the topic of timely diagnosis of chorionic bump. Case Report: A round echogenic mass protruding from the choriodecidual surface, measuring 17.3 x 16.5 x 19.1mm, was identified during a transvaginal examination at 8 weeks' gestation. Uterine cavity with an irregular Gestational Sac with a mean diameter of 29.9mm with poor decidual reaction, observing the amnion inside without evidence of an embryonic pole and a 2.3mm yolk sac. The pregnancy was not viable. Discussion: Etiopathogenesis remains unclear. This case demonstrates that a chorionic bump can be considered a poor prognostic finding in ecosonogram. Conclusion: "Chorionic Bump" is a phenomenon little investigated in ultrasound. The etiology is still unknown. When it is identified, it can be associated with a poor prognostic finding. The most important task for the sonographer is to know how to identify and differentiate it correctly from an early embryonic death.

New insight on etiology: A chorionic bump with partial mole pregnancy case report from Syria

This case report presents the association of a chorionic bump with a partial mole pregnancy in a 37‐year‐old G3P2 woman. The differential diagnosis of a partial mole was considered after transvaginal ultrasonography revealed a chorionic bump. Subsequent pathological analysis confirmed the diagnosis. While the etiology of the chorionic bump remains dubious, we hypothesize an alternative explanation for chorionic bump formation based on the presence of three unique pathological features: necrosis, edema, and hemorrhage.
