“…Another characteristic feature of PMD is aneurismal and varicose dilation of fetal chorionic vessels. Of the 110 cases reviewed, 48 cases of PMD presented data of dilation of fetal chorionic vessels [2,3,9,11,12,13,14,15,17,18,20,21,22,23,24,26,34,35,36,40,41,44,45,46,47,48].

Placental mesenchymal dysplasia (PMD) is characterized by multiple hypoechoic vesicles which are similar to molar changes in the placenta; however, the process of such morphological changes of PMD during pregnancy has not been fully understood. We performed a review of all PMD cases published in English and identified 49 articles including 110 cases. With regard to the gestational age at which the multicystic pattern was seen,approximately 70% of cases were diagnosed at 13-20 weeks of gestation. Another characteristic feature of PMD is varicose dilation of fetal chorionic vessels. As many as 90% of cases were diagnosed as placenta with dilated fetal chorionic vessels in the third trimester. We also report a case of PMD which was found at 10 weeks of gestation according to ultrasonic molar patterns. Serial observations of the placenta using ultrasound and magnetic resonance imaging revealed that multicystic lesions became smaller after 23 weeks. In contrast, dilated placental vessels on the fetal side became apparent at 38 weeks. The present review highlights that placental vesicular lesions of PMD may precede dilation of fetal chorionic vessels during pregnancy. It also indicates the potential of a gradual reduction in size of PMD's placental vesicular lesions by serial study of placental images.

Aim: The study aimed to describe prenatal diagnosis and the outcome of complete hydatidiform mole and coexistent normal fetus (CHMCF). Methods: This was a retrospective case series of 13 patients with CHMCF. Prenatal diagnosis, outcome and development of gestational trophoblastic neoplasia (GTN) were reviewed. Results: Ultrasound diagnosis was carried out in 12 of 13 cases at 17 ± 2.7 weeks of gestation (mean ± SD). Six patients showed abnormalities suggestive of subchorionic hematoma on first trimester ultrasonography (US). Prenatal invasive procedures were performed in 8 of 13 cases (62%). Two women decided to terminate their pregnancies. Four ended in late miscarriages (36%, 4 of 11) between 13 and 21 weeks, and early neonatal death occurred in 1 case (9%, 1 of 11); 5 women delivered a live baby with a mean gestational age of 31 weeks (range 26-37 weeks) with an overall neonatal survival of 45% (5 of 11). GTN occurred in 31% of cases (4 of 13). Conclusions: The first trimester US features of CHMCF are not well-documented. Our series showed that abnormalities of CHMCF could be misdiagnosed as subchorionic hematoma in the early first trimester. When CHMCF is confirmed by expert US, prenatal invasive procedures should be carefully evaluated depending on the associated US findings and exhaustive counseling should be performed.

Placental mesenchymal dysplasia associated with spontaneous ovarian hyperstimulation syndrome

Placental mesenchymal dysplasia (PMD) is a rare disorder of unknown aetiology characterised by placentomegaly, serpiginous surface blood vessels and large cystic villi. Although a mimic of molar pregnancies and other entities, it can be distinguished from them by its association with intrauterine growth restriction or death of a relatively normal fetus and its characteristic histopathology. We report the case of a 20-year-old primigravida who presented at 16 weeks with heavy clotty vaginal bleeding and subsequent miscarriage. The placenta was grossly abnormal and resembled a partial molar pregnancy. PMD was confirmed by microscopic examination. Postmiscarriage, ultrasound revealed enlarged and multicystic ovaries similar to those seen in ovarian hyperstimulation syndrome (OHSS), which returned to normal a few weeks after miscarriage. This is the first report of PMD associated with OHSS, and we hypothesise that the most likely pathogenesis is ovarian stimulation from PMD-derived vascular endothelial growth factor.
